MINING.COM’s most popular stories of 2020

Even setting aside the disruptions and uncertainty created by the pandemic, 2020 was a tumultuous year on mining and metals markets. After the depths of March and April the industry entered the final stretch amid talk of the return of the commodity supercycle and the brightest prospects in more than a decade. 

MINING.COM’s growing community – more than seven million readers during the year – is also an indication of how mining is growing in importance within the broader world as green energy, and with it, copper and battery metals play an ever more central role in our lives.

Bullion off with a bang 

In January, the top five most read articles were about the gold price rally with Iran standing down drops gold price by most in six years scoring nearly 100,000 views. It’s an almost forgotten incident today given interceding events, but geopolitical strife always plays a role in burnishing gold’s safe haven credentials – especially when it comes to nuclear weapons and the Middle East. 

MINING.COM’s readers also flocked to this gold story which summed up the sentiment on bullion boards at the beginning of the year: Gold price rally surprised even world’s top 30 analysts

Gold topped $1,600 an ounce for the first time since 2013 in February and stunningly, predictions of a rise to above $2,000 made at the time panned out just five months later as central banks globally began flooding markets with cheap money to counteract the economic impacts of covid-19. 

 V is for V-shaped

While gold bugs were vindicated, the devastating impact of coronavirus became evident in other markets – dropping an iron ore shipping gauge by 99.9% and a copper price plunge sinking mining stocks

While iron ore prices remained resilient in March at the height of the pandemic panic, copper dipped below $2.00 a pound for the first time since the global financial crisis. 

But even at the time there were first signs of a V-shaped recovery on metals markets with a   40-year cost curve chart showing the copper rout was likely over and China’s $570 billion stimulus raising hopes for copper, iron ore

We’re motoring, what’s your price 

At the beginning of March we launched an EV Metals Index to track the value of battery metals – lithium, cobalt, nickel and graphite – in electric vehicles sold around the world with data going back to the beginning of 2017. 

By May this year, the index had fallen to a 28-month low with empty dealership showrooms around the world only to rocket in October to an all-time high.   

Another green energy milestone was reached in April with renewables overtaking coal-fired power generation for the first time but the pain for the beleaguered US coal industry had been evident for a long time.

Rocks down to electric avenue

While pandemic related stories dominated MINING.COM’s news coverage in the early part of the year, readers were also closely following the emerging mining and electric vehicle narrative: Tesla’s China surprise for cobalt and nickel bulls and boost for rare earths garnered over 50,000 views (and some fierce disagreement).

With predictions that EVs will be $350 billion market in just 15 years and Tesla’s move into mining, news about battery metals ranked highly throughout the year. 

While hard rock lithium miners in particular were struggling in 2020, interest in battery nickel was sparked by Elon Musk’s offer of “giant contracts” to responsible nickel miners despite warnings that the automaker is going to have a hard time finding clean nickel and the launch of a new nickel price as attention shifts to green supply.

Two honks for the muskmobile 

2020 was still early days for mining and electric cars and automakers appear to have a blind spot when it comes to the likely direction of lithium, cobalt and nickel prices. 

Our most discussed article of the year was an opinion on Tesla’s much anticipated Battery Day. Mines are the biggest holes in Tesla’s $25,000 car plans may be only the first clash between big tech and big mining as a 100%-EV world approaches.

Not sitting on a gold mine

2020 was also the year short sellers went after two of the biggest gold projects in the world, both located in Alaska. In July, JCap, a firm famous for exposing overvalued Shanghai stocks, accused Northern Dynasty of “gaslighting investors” about its Pebble project and said Novagold’s Donlin is “a stock promote, not a mining plan.”  

Novagold shot back, saying JCap wove “a tapestry of deceit” and followed up with a lawsuit. Northern Dynasty also engaged lawyers after calling the report “fatuous and flimsy”, but the project suffered a setback in November when the US Army Corps of Engineers denied a key permit.  Northern Dynasty is fighting on to build the giant copper and gold mine. 

In September, Barrick’s controversial Pascua-Lama project on the border between Argentina and Chile, received a court order for “total and definitive” closure.

Sitting on a gold mine

The rally in gold and silver prices remained at the top of the news, but away from financial markets gold was also a point of discussion with  Papua New Guinea’s row with Barrick Gold over the Porgera mine breaking in April and remaining a contentious topic throughout the year. 

Whether the deal struck in October, giving the government a large stake in the mine brings finality to the dispute remains to be seen.

Canada advanced in the race to become the world’s top gold producer in July after the approval of Iamgold’s Côté project in July while Pure Gold’s Ontario mine poured first gold this week. But Russia seems more likely to overtake China particularly if Polyus gives final approval for Sukhoi Log which could become a 2.3 million ounce per year mine

You’re fired! You’re hired! 

The beginning of June saw the news about Rio Tinto destroying a 46,000 Aboriginal cultural site that led to the ousting of top executives including CEO Jean-Sébastien Jacques in September. 

While Rio is rebuilding ties with indigenous Australians the destruction of Juukan Gorge in Western Australia will likely reverberate in the mining industry for years to come.

In contrast, Glencore CEO Ivan Glasenberg’s departure was signposted well in advance with insider Gary Nagle, head of its coal division, tapped to set the Swiss company’s strategy to cut emissions by 40% in 15 years.

Watch a 400,000-tonne ship sink to the bottom of the ocean

Amid stiff competition, the iron ore spectacular run to near-decade highs is one of the biggest stories of the year, but in June visitors to MINING.COM were more interested in watching a 400,000-tonne ore carrier sink to the bottom of the ocean, reading about how the moon is richer in metals than previously thought and a gold discovery in Egypt that received a combined 200,000 visits.

Diamonds in the rough, and in batteries

Making news early in the year was a slump in the diamond market and Rio Tinto’s decision to end production at the Argyle mine in Western Australia, with the iconic producer of pink diamonds officially shutting its doors after 37 years and 865 million carats in November

MINING.COM’s readers also sought out lighter fare as the pandemic raged – Ritchie Bros. sells Volvo ‘Gold Rush’ excavator for $290,000 was a favorite while a story about Roman-era warships found at a Serbian coal mine also provided a diversion.

With 204,000 readers, our second most popular story of the year – NASA finds rare metal asteroid worth more than global economy  – appeared at the end of October, one of many science and technology stories that caught the attention this year including: Gold, vanadium, europium reveal the existence of mysterious particle and Nano-diamond battery that lasts for 28,000 years closer to becoming commercial product.

Bad bullion news sells

In August, the gold price reached a new all-time high above $2,000 as investors piled into ETFs in record numbers. The precious metal went into correction mode over the following months and one of the articles covering the decline ended up as MINING.COM’s most popular story of the year, with 415,000 reads. 

The future of the gold industry was under discussion the entire year amid countervailing warnings that we’re a long, long way from running out of gold and that the industry is facing a reserves crisis needing $37 billion worth of projects by 2025.

Supercycle recycle

While gold was retreating, De Beers had some good news for the suffering diamond market, saying that prices had bottomed out and towards the end of the year – and after many wild swings – copper and iron ore prices (joined by zinc and nickel) were setting multiyear highs as China sucked up the world’s excess metal and the incoming US administration promised infrastructure spending, green stimulus and support for domestic battery metal mining.

Court orders renew of Montagne d’Or concessions

Orea Mining (OREA: TSX) announced on Thursday that the French court ordered the renewal of the Montagne d’Or mining concessions within six months.

Located in French Guiana, the open pit gold mining project hosts Proven Mineral Reserves of 8.25 Mt at 1.99 g/t (530,000 oz) and Probable Mineral Reserves of 45.87 Mt at 1.50 g/t (2.2 Moz).

The Montagne d’Or joint-venture (owned 44.99% by Orea and 55.01% by Nord Gold SE) submitted renewal applications for a 25-year period for two core mining concessions in December 2016. In the absence of a decision from the Minister of Economy the JV filed proceedings in February and March 2019 in the Administrative Court of Cayenne in French Guiana to invalidate any implicit refusal.

Midday Thursday, Orea’s stock was up 35% on the TSE

The Court ordered the state to extend the mining concessions and to set the duration of the extensions within a period of six months from the notification of the court judgment. The Minister of Economy will have two months to appeal the decision.

“The Court also noted the completeness of the applications and the JV’s financial and technical capabilities to develop the project. Now that the mine redesign is essentially complete, culminating in years of outstanding work by the JV to make this project technically and environmentally exemplary, we now see a clear path for the development of one of the best grade open pit gold deposits in the Guiana Shield” said Rock Lefrancois, President and CEO of Orea. 

According to the company, the current schedule is to finalize the environmental and mining authorization applications in the first quarter of 2021.

Midday Thursday, Orea’s stock was up 35% on the TSE. The company has a C$37 million market capitalization.

McEwen completes feasibility for Fenix

A feasibility study has outlined a nine and a half year mine life for McEwen Mining’s (TSX: MUX; NYSE: MUX) 100%-owned Fenix project in Sinaloa state, Mexico.

The Fenix project is a proposed redevelopment plan for the company’s El Gallo complex, and involves building a mill at the existing mine site that initially will reprocess the existing heap leach material, and then transition to process ore from open pits at the El Gallo Silver, Palmarito, Carrisalejo and El Encuentro deposits.

The feasibility – published on the final day of 2020 – envisioned average annual production of 26,000 oz. gold in Phase 1 (years one to six) and 4.2 million oz. silver-equivalent in Phase 2 (years seven to nine and a half).

Company is targeting annual production of 300,000 gold-equivalent ounces in 2025

Using base case prices of $1,500 per oz. gold and $17 per oz. silver, the feasibility estimated an after-tax net present value at an 8% discount rate of $32 million and post-tax internal rate of return of 28%. Those numbers rise to an NPV of $98 million and IRR of 55% at $1,900 per oz. gold and $25 per oz. silver.

The study estimated initial capex in the first phase of $42 million and a further $24 million of incremental capex in year six. Using the base case, the after-tax payback period is 3.6 years and drops to 2.8 years at higher metal prices.

During the first phase in years one through six, cash costs are estimated to run to $1,035 per oz. gold and all-in sustaining costs to $1,042 per ounce gold. During the second phase in years seven through to the end of the mine life, cash costs are forecast to be $14.20 per oz. silver-equivalent and AISCs will come in at $14.28 per silver-equivalent ounce.

The company will store tailings in a mined-out open pit at the El Gallo gold mine, which it says “creates multiple benefits, most importantly a secure containment of tailings enabling better reclamation results.”

“The critical path environmental permits are in hand for the first phase of production,” Rob McEwen, the company’s chairman and chief owner stated in a press release. “Our next steps will involve detailed engineering, assessment of procurement options, and the evaluation of financing alternatives.”

The current operation at the El Gallo gold mine is a fully permitted site. SEMARNAT, Mexico’s Federal Environmental Authority, granted a permit in September 2019 for Phase 1, which allows the company to add a mill and leach circuit near the existing facilities to reprocess material from the heap leach pad. The permit amendment also covered the backfilling of a previously mined pit with mill tailings, as part of a concurrent closure plan for the El Gallo gold mine.

Permits for Phase 2 are required to expand the footprint of the process plant, and the haul road, and to augment the tailings volume allowed in the depleted pit.

According to the company’s Nov-Dec. 2020 presentation, management is targeting annual production of 300,000 gold-equivalent ounces in 2025, up from 160,000 to 170,000 gold-equivalent ounces in 2021. Production will come from El Gallo, its Fox complex in Timmins, Ontario, Gold Bar in Nevada, and San Jose in Santa Cruz, Argentina.

McEwen is the company’s top shareholder with 20% (82.2 million shares), followed by Van Eck Associations (18 million), BlackRock (10.2 million); and Mirae Asset Global Investments (8.2 million).

Over the last year, McEwen Mining has traded in a range of 76¢ and $2.02 per share. At presstime in Toronto the company was trading at C$1.27 per share. The miner has about 409 million common shares outstanding for a market cap of about C$519.2 million.

Gold price heads for largest yearly gain in a decade

Gold prices are set for their biggest annual advance in a decade after a tumultuous year, with the economic impact brought by the coronavirus pandemic playing a key role in support of the haven metal.

Bullion hit a record high earlier in August as investors feared an unprecedented wave of stimulus by central banks and governments would lead to currency debasement and inflation. Holdings in gold-backed exchange-traded funds also set an all-time high in October.

While prices ebbed as the roll-out of vaccines injected optimism into financial markets, the dollar’s continued weakness has helped support gold into the year-end. This week, the greenback dropped to its lowest since April 2018.

Looking ahead, there is little consensus from Wall Street’s biggest names on bullion’s direction. Morgan Stanley sees gold and other precious metals coming under pressure as financial markets normalize and longer maturity bond yields rise. On the opposite end, HSBC Holdings Plc expects gold to climb higher on growing economic uncertainty.

Much of gold’s performance next year will depend on whether the eventual return to normality is outweighed by ongoing stimulative policies. Led by Chair Jerome Powell, the US Federal Reserve has signaled that its ultra-easy monetary conditions will last throughout 2021. Meanwhile, efforts to pass further fiscal stimulus through the Senate have hit another roadblock.

“Gold’s main drivers — weaker US dollar and low real interest rates — are likely to provide support even as vaccines are distributed around the world,” said Vasu Menon, executive director, investment strategy, at Singapore-based Oversea-Chinese Banking Corp. “With the lower-for-longer Fed, it is too early to throw in the towel on gold,” he said in an email to Bloomberg.

The Fed will remain “extraordinarily accommodative” through 2022 and an increasingly progressive Democratic Party is looking to borrow and spend aggressively, said Tai Wong, head of base and precious metals derivatives trading at BMO.

“Based on that, the US dollar has been slumping badly and can’t manage any rally, which is bullish gold,” he said. “However, if the vaccine really is effective and we have the pandemic beat by summer, that may limit gold gains.”

Spot gold edged 0.1% higher to $1,897.70 per ounce by 11:45 a.m. EST Thursday. US gold futures advanced 0.4% to $1,901.40 per ounce on the Comex.

IAMGOLD, AngloGold Ashanti close Mali mine sale

IAMGOLD C(TSX: IMG) (NYSE: IAG) and joint venture partner AngloGold Ashanti announced Wednesday that they completed the sale of their collective interests in Société d’Exploitation des Mines d’Or de Sadiola S.A. to Allied Gold Corp. (TSE: ALG)

SEMOS’ principal asset is the Sadiola gold mine, in the Kayes region of Western Mali. Sadiola, one of the three assets AngloGold Ashanti put on the chopping block this year and IAMGOLD’s founding asset, is also owned by Mali’s government, which has an 18% interest.

The $150 million deal was first announced in December 2019 but delayed in August over a coup, which was Mali’s second in less than ten years.

The $150 million deal was first announced in December 2019 but delayed in August over a coup, which was Mali’s second in less than ten years

The coup capped weeks of protests demanding that Malian President Ibrahim Boubacar Keita step down. Keita faced opposition criticism for alleged corruption and nepotism within his administration, and the mishandling of an escalating Islamist insurgency in the West African nation.

B2Gold, Resolute Mining, AngloGold Ashanti, Hummingbird Resources, Roscan and Cora Gold said operations and staff were unaffected, but traders sold shares because of increased political risk.

Immediately prior to the transaction, the companies said, a dividend of $20 million was declared and paid by SEMOS pro-rata to its shareholders. IAMGOLD and AngloGold Ashanti each received a cash dividend of $8.2 million and the Republic of Mali received a cash dividend of $3.6 million.

“We are pleased to complete this transaction, which underpins our commitment and focus on a prudent capital allocation strategy as we embark on a transformational path with the execution on our growth pipeline,” IAMGOLD CEO Gordon Stothart said in a press release.

“The Sadiola mine was the founding cornerstone asset and building block of our company, and we would like to recognize the Sadiola team, surrounding communities and all stakeholders for their valued support over more than twenty years.”

Minnova closer to restarting PL mine in Manitoba

Toronto-based Minnova Corp. (TSXV: MCI) announced that it is advancing its plans to restart the past-producing PL Mine, located in the Flin Flon – Snow Lake Greenstone Belt of Central Manitoba, Canada.

In a press release, the miner said despite having conducted a relatively modest work program that included 13-hole step-out drilling, field mapping and prospecting, it made significant advances at PL in 2020.

Among such positive results that put the company one step closer to restarting the mine is the extension of the strike length of the FW Tonalite, a major lithology that occurs in the footwall to the PL deposit resource, which is currently defined over a strike length of 1.2 kilometers and is still open on strike.

The past-producing PL Mine is located in the Flin Flon – Snow Lake Greenstone Belt of Central Manitoba

Minnova reported that it also identified a number of previously unmapped high angle structures in the FW Tonalite, some of which are associated with anomalous gold mineralization. In consequence, the FW tonalite is now considered a prospective target for hosting gold mineralized structures.

The miner also discovered high-grade mineralization at surface on the permitted mining lease that will be targeted for infill drilling and possibly a surface bulk sample in 2021 and identified high priority targets located off the mining lease, which will be also targeted for drilling in the new year.

“The culmination of this work is the development of a new geological model that will improve our infill and step-out drilling planned for current PL deposit mineralized trends and new high angle structures,” the company said.

“We will continue our discussions with various contractors to optimize the 2017 feasibility study restart plan with updated capex and opex cost estimates.”

The restart of PL forecasts an average annual production rate of 46,493 ounces over at least five years.  

According to Minnova, the PL gold mine has a relatively short pre-production timeline forecast at 15 months, benefits from a valid underground mining permit, an existing processing plant and over 7,000 meters of developed underground ramp to -135 meters depth.

Gold price higher as dollar hits multiyear low

Gold prices edged higher on Wednesday, as the prospect of increased fiscal aid pushed the US dollar to another multiyear low. However, the ongoing covid-19 vaccine rollouts and increased risk appetite limited bullion’s gains.

Spot gold advanced 0.4% to $1,885.05 per ounce by 11:35 a.m. EST, while US gold futures rose 0.3% to $1,889.30 per ounce in New York.

On Wednesday, the dollar index fell to its lowest since April 2018 following US Senate Majority Leader Mitch McConnell’s decision to delay a vote on increasing covid-19 relief checks to $2,000.

This worked in favour of bullion, though only slightly, as investors’ risk appetite remains high, which is evident in the equities market.

US stocks rose once again on hopes of additional fiscal stimulus and on optimism over vaccine rollouts, as Britain became the first country to approve a vaccine developed by AstraZeneca and Oxford University.

“The bigger picture is that gold is still holding up incredibly well at these price levels and the fiscal and monetary stimulus will still be there in 2021 as the pandemic is hitting hard in the US, Europe,” Bank of China International analyst Xiao Fu told Reuters.

Investors now await the January 5 Georgia runoff elections that will determine which political party will control the US Senate, with expectations for more stimulus under a Democrat-controlled Senate and House.

2021 outlook

In anticipation of further stimulus measures, many analysts expect the US dollar to continue its downward trend heading into the new year, thus elevating the status of gold.

In its recent 2021 outlook report, JP Morgan wrote:

“We expect the US dollar to weaken modestly as the global economy continues to heal. Investors should consider diversifying their portfolios to gain exposure to assets denominated in other currencies.”

In November, analysts at Goldman Sachs said they expect gold to soar through 2021 “as the coronavirus recession gives way to higher inflation.” As a result, they see gold prices reaching as high as $2,300 an ounce.

Exploring for pegmatite-bound commodities without drilling, blasting

A project put together by 13 institutions from five EU member states, the UK and Norway was awarded €8.3 million in funding to work on improving access to, and quality of, geological and geophysical data to stimulate investors to explore Europe for clean energy metals and minerals.

The project is called Greenpeg and it has developed two toolsets for the exploration of buried LCT and NYF pegmatites. These toolsets include three new instrumental techniques and devices, namely, a piezoelectric sensor, a helicopter-complementary nose stinger magnetometer, and a drone-borne hyperspectral imaging system. 

According to its creators, the use of a modular sequence of optimized exploration methods from ground, air and space-based information decreases exploration costs because there is no need for drilling and blasting which, in turn, dramatically reduces emissions. 

Greenpeg has developed two toolsets for the exploration of buried LCT and NYF pegmatites

“Innovation needs raw materials from mining. The economic value chain depends on a secure raw materials supply. Europe’s ambitious e-mobility plan will rely on both,” the initiative’s website states. “Increasing requirements for responsible sourcing in the raw materials value chain, have put pressure on the industry to engage in responsible sourcing and responsible business conduct and to perform relevant due diligence that goes beyond legislative obligations. This starts upstream with exploration.”

Greenpeg’s approach focuses on designing a strategy based on the specific characteristics of the target pegmatite ores. At present, this strategy is concentrating on ores that present low contrast of petrophysical properties compared with their wall rocks; high mineralogical variability in different pegmatite types; relatively small orebody volumes (0.01 to 5 million m³) and lateral extent; pegmatites in clusters (fields); and Li, B, F, Cs, Be, Ta and Sn halos (10 to 100 m scale) around the bodies.

The methodology testing and optimization are being performed in three European demonstration sites: in Wolfsberg, Austria; south Leinster, Ireland; and Tysfjord, Norway. Field-testing approaches have been divided into three investigation scales: (1) province scale (500 – 10000 km²); (2) district scale (50 – 500 km²); and (3) prospect scale (<50 km²). 

“Resource inventories have become an important measure in raw materials policy-making. Greenpeg technology will broaden our knowledge bases of industrial minerals and critical raw materials,” project creators say. “This in turn will help feed the resource base for green technology ‘Made in Europe’.”

Education for a more sustainable mining future

“…the objectives of an observation give meaning to what defines sustainable mining. Thus, the observations of host local communities in terms of cultural values and economic livelihood, which is linked to environmental endowments, inform their perceptions of sustainable mining. The profit and revenue interests of both governments and industry players inform their definitions of what sustainable mining pertains. In this regard, building consensus on what sustainable mining pertains requires a dispassionate academic analysis and model building.” [Horowitz, L. Section 2: Mining and sustainable development. J. Clean. Prod. 2006, 3, 307–308]​

That’s the ‘why’. ‘How’ we get to the point where there is real consensus around sustainable mining development is going to take commitment, hard work, and probably just a few mindset changes. After all, there’s far more to sustainable mining than just the mineral extraction process. We touched on some of the ‘must haves’ when it comes to creating consensus for building a more sustainable mining industry in a previous article.

Ultimately, sustainable mining is about encouraging balance between all involved stakeholders across social, environmental, economic and governance factors. Reaching that goal though demands educated and impartial analysis of all these areas followed by equally as impartial model building based on those analytics.

Ultimately, sustainable mining is about encouraging balance between all involved stakeholders across social, environmental, economic and governance factors


​One proposed framework ​for developing project-specific background understanding of sustainable mining advocates the use of assessment tools built on ‘community engagement’ across a range of metrics. These metrics include research, economic valuations, and environmental monitoring. However, the model presupposes a certain degree of local experience and expertise in research and environmental monitoring, which may not always be available. It is a start in the right direction though.

Is improved environmental literacy the answer?

Given that the health of the environment plays a pivotal role in the both the social and economic health of local communities, it makes a lot of sense to think that improving environmental literacy is at least part of the answer! There are parts of the world where a lack of skills in this area is contributing to unsustainable development with serious implications for affected communities.

Therefore, developing education programs to create / improve community environmental literacy, particularly in countries that rely heavily on mineral resources, are definitely a good idea. The SPEAK program in Afghanistan is one such initiative implemented by the UN.

To work effectively though any environmental literacy program must be both local and regional in scope to ensure the policies that evolve from them are broad and sustainable in the wider context. Some of the topics that ideally should be incorporated into these programs include education about:

  • Links between geology and human health – the field of medical geology ​is attracting a lot of interest as we strive to better understand the effects of the geology of our natural surroundings on human and animal health. For example, some types of health issues attributed to mining activities are also indicative of the local geology. Those same activities in a completely different geological setting may not cause the same problems, or not to the same extent.
  • Successful agricultural rehabilitation of old mines and waste areas
  • Development / reestablishment of viable livestock grazing land post mining

The latter two are particularly valuable because they’ll help create sustainable livelihoods for communities once mining operations cease.

Ideally, environmental literacy training will involve relevant case studies and active hands on problem-solving scenarios that strengthen local capacity for both planning and protecting their own ecosystems. Ultimately, the more the locals understand what they’re dealing with, and the repercussions for their social, environmental and economic systems, the better equipped they are to bring valid, and valuable, contributions to the consensus discussion table.


The development of livestock grazing land, for instance, may involve grazing trials on recently reclaimed land to ensure adequate grazing and nutrition for the stock and, importantly, measure levels of mining chemicals in the products produced from the livestock. This type of first-hand exposure to cause and effect links between mining and local ecosystems will help educate and motivate local communities to play a more educated role in decisions about mining activities that affect them.,

Pathways to community environmental learning

There’s no doubt that modern diagnostic technologies like earth observatory satellite systems and geographic information systems are making their presence felt via dispassionate assessments of mining’s footprints across local landscapes. These and other similar technologies have already been used in studies (some community initiated) to assess how local land use is being affected by large-scale surface mining in countries like Ghana and Tanzania. When combined with local knowledge and perceptions, the result is a powerful tool that can be used to improve:

  • the mining sector’s performance across environmental, social and economic sustainability metrics,
  • how local communities contribute to discussions about sustainable mining operations around these same metrics,
  • overall stakeholder motivation for building cohesive agreement about sustainable mining

Using environmental technology effectively requires training. Working on the premise that environmental literacy programs can be established, they should include training around topics like:

  • Understanding geographic information
  • Digital data management
  • Deployment and operation of drones
  • GPS use
  • Mobile communications
  • Spectral signatures of relevant chemicals, minerals, and environmental characteristics

This would equip communities with the skill sets to proactively get involved in monitoring and assessing local mining activities. If companies know that locals can, and will be, keeping a technologically watchful eye out for environmental irregularities on or around their operations, they’re far more likely to ‘care’ about what they’re doing. Indeed, mining companies should be welcoming this interaction because it will act as a back up to their own environmental monitoring systems!

Involving the education system

Getting academic institutions on board is a logical way to help ensure this happens in a systematic and effective manner, especially if mandated by official government policy. It also complies with UNESCO’s ESD program, which recognises the need for people to be educated in specific competencies that lead them to a greater understanding and awareness of sustainability,

Currently, most tertiary institutions that offer mining degrees provide minimal training in sustainable mining, or none at all

To this end, places of learning in countries with active mining industries must develop basic courses within their syllabus that train people in the collation, use, and understanding of environmental technologies and geographic information. Further, the course content must be presented in ways that teach students to actually think and behave in sustainable ways. This may be through workshops, observation assignments, case studies, hypothetical scenarios, and the like.

Why get the training?

This type of training is essential for future mining industry employees, interested community members, and government employees.

Future mining employees, once trained to be more ‘sustainability sensitive’, can become information contacts and liaison officers between mining companies and local communities and thus facilitate meaningful dialogues between affected stakeholders. They can also perform their jobs within the industry with an increased awareness of the sustainability aspects of policy decisions, and development and operational processes.

Community member graduates could get involved in independent advisory groups dedicated to sustainable mining development that provide advice to stakeholders and keep local communities ‘in the loop’. They could also bring local (indigenous) knowledge to the negotiation table, bridge the divide between mining companies and communities, and get involved in SLO’s (social licence to operate).

Likewise, government employees tasked with the responsibility of overseeing mining operations would understand the technologies involved and the information they produce. This would help create greater awareness of sustainability and environmental accountability at bureaucracy level, leading to more environmentally, socially, and economically responsible policy decisions.

Further to these educational initiatives, governments must consider formalising ie legislating requirements for mining companies to share the geographic information they collect with primary and secondary stakeholders. These stakeholders can then use the information both to further their understanding of a project’s sustainability and to monitor its environmental impact (which is where training to be able to do this is essential). Mining jurisdictions that allow mining companies to keep this type of pivotal information ‘out of the public eye’ are paving the way for secrecy, misinformation, cover-ups, and potential disaster.

The current situation

Currently, most tertiary institutions that offer mining degrees provide minimal training in sustainable mining, or none at all. This is particularly the case in developing countries that ironically rely heavily on their resource sector. However, if we’re to change the future, we must change the way we do things in the present. At present, the way we’re doing things on the education front is not significantly contributing to the development of future generations that can ‘think and behave in sustainable ways’ in relation to mining.

Metso Outotec to deliver processing technology to Russia copper concentrator

Metso Outotec has signed a contract for the delivery of key minerals processing technology to a new high-capacity copper concentrator in Russia. 

The customer and the contract value are not disclosed. However, deliveries with similar scope typically exceed 100 million euroes, the company said. 

The order is booked in Metso Outotec’s fourth quarter 2020 orders received. In June 2020, the company received an 23 million euro order for two primary crushing stations for the same concentrator plant.

The concentrator will have four production lines with a total processing capacity of at least 80 million tonnes of ore per annum. Metso Outotec will deliver the main process equipment for grinding, flotation and dewatering.

These include grinding mills, TankCell® flotation cells in different sizes between 30 and 630 cubic meters, pressure filters, on-line sampling and analyzing system, field instrumentation and Proscon® automation for the whole concentrator plant. Equipment deliveries will take place during 2022 and 2023.

“We are extremely pleased about this order. The new concentrator, based on Metso Outotec’s proven proprietary technology, will enable our customer to build and develop their operations in a sustainable way and get the best value from their assets,” Stephan Kirsch, president of the minerals business area at Metso Outotec, stated in a press release.

Brazil, Australia iron ore shipments set record high

The total volume of iron ore dispatched to global destinations from Australia and Brazil was 29.7 million tonnes from December 21-27, the highest since June 2019, according to a survey from Mysteel.

Over the survey period, Australian iron ore shipments from its ten ports bound for global destinations hit 21.7 million tonnes, and the tonnage shipped from Brazil’s nine ports reached 8 million tonnes.

Prices for iron ore have more than doubled in 2020

Iron ore outperformed all commodities in 2020, more than doubling to record highs on strong Chinese steel demand.

As the world’s largest producer of steel at 1.1 billion tonnes in 2020, China imports 60% of its iron ore from Australia. Bilateral relations between the two countries soured earlier this year after Australia supported a growing call for an international inquiry into China’s handling of the coronavirus pandemic. The ongoing tensions haven’t had a big impact on the iron ore trade so far.

Australia’s government said it foresees China’s pull on Australian iron ore exports remaining strong in the next few years.

“Mining exports are expected to fall by 0.5 per cent in 2020-2021 and grow by 5 per cent in 2021-2022,” it said in its mid-year economic report.

Rally

Prices for iron ore have more than doubled in 2020, putting the steelmaking raw material on track to be the top-performing major commodity globally for a second straight year as speculative money floods in and Chinese demand holds firm.

The most active iron ore futures on the Dalian Commodity Exchange have gained 37.8% this quarter and 21.5% in December alone.

Some market analysts, however, expect prices to moderate over the next two years. 

S&P Global Ratings said in a report on Vale it expects iron ore prices to average $85 per tonne in 2021, and $70 per tonne in 2022.

Commonwealth Bank of Australia said in a report that iron ore prices could slip below $100 per tonne next year.

Nevada Copper marks construction milestone at Pumpkin Hollow

Nevada Copper (TSX: NCU) announced on Tuesday it has completed the underground materials handling system of the main shaft at its Pumpkin Hollow underground mine in Yerington, Nevada.

Completion of the materials handling system represents a “significant milestone” in the construction of the underground project, the company said. The entire project included sinking the vent shaft, sinking the main shaft and construction of the processing plant.

Pumpkin Hollow was the first US copper mine to come on line over the past decade

The materials handling system would result in a significant increase in hoisting rates, from currently 1,000 tpd to ultimately 5,000 tpd once commissioning and ramp-up are completed. This is expected to enable the underground mine to deliver substantially higher volumes of ore directly from the mine to the processing plant.

“With the completion of the materials handling system, we can now utilize the full hoisting capacity of the main shaft as we ramp up the mine towards full production,” CEO Mike Ciricillo said in a press release.

Earlier this month, Nevada Copper received a financing package including $31 million in cash for completing the ramp-up of the underground project.

Pumpkin Hollow was the first US copper mine to come on line over the past decade. The underground mine is capable of producing 50 million pounds of copper during a 13.5-year mine life.

Shares of Nevada Copper gained 6.2% by 12:10 p.m. in Toronto. The copper miner has a C$189.7 million market capitalization.

Newcrest goes ahead with Gorbea project in Chile

Mirasol Resources (TSX-V: MRZ) announced that Newcrest (TSE:NCM) has exercised its option to enter the farm-in phase of its joint venture to develop the Gorbea gold project in Chile by making a $500,000 payment to Mirasol.

To date, Newcrest has completed 5,426m of drilling and spent more than $9 million on the project, exceeding the minimums required under the option phase. The drilling highlights include 0.52 g/t Au and 6.81 g/t Ag over 164m (from 372m) at hole ATL-DDH-001A and 0.54 g/t Au and 2.65 g/t Ag over 129m (from 363m) at hole ATL-DDH-010.

The Gorbea package was optioned to Yamana Gold from 2015 to 2018. During this period, Yamana spent more than C$10m on exploration expenditures

To complete the first farm-in phase and vest an initial 51% in the Gorbea project, Newcrest is now required to complete at least $15 million in exploration expenditures over 4.5 years and drill a minimum of 8,000m.

The first 2,000m of drilling is to be completed before the end of 2021 and the additional 6,000m must be completed before the end of 2022.

The Gorbea package was optioned to Yamana Gold from 2015 to 2018. During this period, Yamana spent more than C$10m on exploration expenditures and drilled more than 11,000m.

In early 2019, Mirasol entered into a new agreement with Newcrest to further advance exploration.

Ares to provide fluorspar for breakthrough technology

Ares Strategic Mining (TSXV: ARS), the Canadian company that owns the only permitted and producing fluorspar mine in the US, received this week technology commitments that enable it to manufacture a fluorspar product not previously anticipated at its Utah operation.

According to Ares, its manufacturing partner, the Mujim Group, has developed a new technology able to produce fluorspar lumps from material that was previously unsuitable for their manufacture. 

Fluorspar lumps are used in the ceramic, fiberglass, and glass industries, as they reduce the refractory melting point, promote the flow of slag, and enable the separation of slag and metal. The product also assists with desulfurization and dephosphorization during the smelting process and acts to enhance the tensile strength of forged metals.

Fluorspar lumps are used in the ceramic, fiberglass, and glass industries, as they reduce the refractory melting point, promote the flow of slag, and enable the separation of slag and metal

The lumps, however, are rare and even though the United States classified fluorspar as a critical material in 2018, the country still imports most of the fluorspar it consumes.

Given this context, Ares said that it may be possible for the company to become the first vertically integrated lumps manufacturer in America. 

“This new technology potentially opens a whole new product line to us, which would run alongside our currently anticipated acidspar and metspar products,” James Walker, the firm’s president and CEO, said in a media statement. “We anticipate concluding a joint venture agreement to use this technology, so we can complement our manufacturing industrial reach and operating flexibility.”

At present, the Mujim Group -which operates several fluorspar mines in Thailand and Laos- is supporting Ares in the expansion project of its 1,447-acre Lost Sheep mine, located in Juab County, Utah.

The Canadian miner is currently in the process of ramping up production through new equipment, designing a new plant tailored to the mine’s ore, engaging new staff and strategic partners, and building a global customer base. 

“We have ambitions to create a large mining operation, capable of producing industry-grade metspar and acidspar for the world markets,” Walker said.

Cobalt may substitute platinum in fuel cells

A team led by researchers at the Pacific Northwest National Laboratory in the US designed a highly active catalyst that contains cobalt interspersed with nitrogen and carbon and, thus, doesn’t rely on platinum to spur the necessary chemical reaction.

In a paper published in the journal Nature Catalysis, the scientists explain that their invention is four times more durable than similarly structured catalysts made from iron —another platinum substitute. 

In their view, their findings show promise for fuel cells in transportation as proton exchange membrane fuel cells paired with hydrogen require very active catalysts for the chemical reaction —the oxygen reduction reaction that makes a fuel cell efficiently function— to take place.

The researchers started looking at cobalt because, even though PGM tends to be the most common catalyst material for PEM fuel cells, it is very expensive, while other options such as transition metals quickly degrade in the acidic proton exchange membrane fuel cell environment.

The researchers achieved the highest activity in fuel cells reported for non-iron, platinum group metal-free catalysts to date

“We knew that the configuration of cobalt with nitrogen and carbon was key to how effectively the catalyst reacts and that the active site density was critically important for performance,” Yuyan Shao, lead author of the study, said in a media statement. “Our goal was to really improve the reaction activity of cobalt-based catalysts.”

Shao explained that he and his team immobilized cobalt-based molecules in the micropores of zeolitic imidazolate frameworks, which served as protective fences to decrease the cobalt atoms’ mobility and prevent them from clustering together. They then used high-temperature pyrolysis to convert the atoms to catalytically active sites within the framework.

Within this structure, they discovered that the density of the active sites significantly increased, in turn raising the reaction activity. This achieved the highest activity in fuel cells reported for non-iron, platinum group metal-free catalysts to date.

The team also discovered, for the first time, significant differences in demetallation, where metal ions are leached out of the catalyst and that catalyst then loses activity. They also found that oxygen radicals from hydrogen peroxide, a byproduct of oxygen reduction in fuel cells, attack the catalysts and cause performance loss.

“In the end, we were able to not only improve the activity of the cobalt-based catalyst, but we significantly improved the durability,” Shao said. “Our further investigation led us to discover the mechanisms that typically degrade these types of catalysts.”

US Gold Corp’s shares up on Wyoming project drill results

U.S. Gold Corp. (NASDAQ: USAU) announced Monday additional results of the recent 29 hole drilling program for its CK Gold Project, an advanced stage gold and copper exploration project located near Cheyenne, Wyoming.

The CK Gold Project deposit is a development stage, large-tonnage, gold-copper deposit with high-grade mineralization exposed at the surface surrounded by a large, low-grade zone with potential for expanding resources. The project’s main zone deposit provides a NI 43-101 compliant resource at 926,000 Measured and Indicated oz Au and 223mm lbs Cu and 174,000 Inferred oz Au, 62.5mm lbs Cu.

The miner reported 176.8 meters (600 feet) of continuous gold, copper and silver mineralization with an average gold equivalent grade of 1.003 g/t.

Hole CK20-02c shows continuous gold and copper grades for the length of the hole with better grades near surface than the neighboring hole, the company said.

“With hole CK20-02c, the second of seven holes within the resource designed to collect metallurgical samples, again we confirm two key aspects of the CK Gold resource,” George Bee, U.S. Gold Corp CEO said in a media release.

Firstly, the continuous nature of the mineralization with attractive grades starting at surface. Secondly, looking towards project development if our PFS and FS show promise, a project that we believe should produce payable material at the start of mine operations without the common delays and up-front costs associated with pre-stripping waste,” Bee said.

“This has a very beneficial effect on project economics compared to most other projects where significant costs are incurred pre-stripping waste material.”

U.S Gold Corp’s shares were up 4.5% at Monday’s close. The company has a $79 million market capitalization.

Major milestone for Mason Graphite at Lac Gueret

Mason Graphite (TSXV: LLG; US-OTC; MGPHF) has reported that testing of lithium-ion batteries containing graphite from its 100%-owned Lac Gueret project in Quebec, 660 km north of Montreal, has reached a key milestone for potential electric vehicle application.

The lithium-ion batteries, which contained anodes made from coated spherical graphite (SPG) manufactured from graphite flake concentrates mined at Lac Gueret, achieved 500 charging/discharging cycles while maintaining 85% of the battery’s original capacity, bettering the minimum industry requirements of 80%.

“This is the culmination of five years of hard work to arrive at a product that has credibility in the market,” Jean L’Heureux, Mason Graphite’s chief operating officer, said in an interview. “The 500 cycles target is considered to be a significant milestone in the battery industry, and we were also able to demonstrate that it is repeatable.”

During the battery charging cycle, the SPG acts as a host for lithium ions that migrate through the electrolyte from the cathode (usually made from lithium metal oxide) to the anode, where they attract electrons from an external circuit and are stored as lithium in the anode’s graphite structure.

Conversely, during discharge, lithium ions are released from the anode as they give up electrons to the external circuit, move to the cathode, and are again stored as lithium.

“This is the culmination of five years of hard work to arrive at a product that has credibility in the market”

Jean L’Heureux, chief operating officer, MASON GRAPHITE

To produce SPG grains for use in the battery’s anode, the graphite flakes must first be reduced to about 40 microns in size and then rounded to produce SPG grains of between five and 20 microns. These micronized and spherical graphite structures, which resemble a clenched fist, are then purified using sulphuric acid. 

“The higher the purity of the SPG, the better it is at storing the maximum amount of energy and maintaining the reversible capacity of the battery,” said Henri Wilhelm, the company’s advanced applications and product specialist. “The SPG particle grain size and shape are also important, as the micron-sized rounded particles allow for a thin and densely packed anode.”

The company has been able to produce SPG grains of 99.95% purity with an average grain size of 20 microns, he said.

The final stage involves coating the graphite with a carbonaceous precursor and baking it at over 1,000 degrees Celsius, which produces a hard, thin carbon shell that “smoothens” and reduces the grain’s surface area, improving the battery’s cycling efficiency and energy storage capacity. 

The coating also prevents the graphite from reacting with the battery’s electrolyte, which reduces the battery capacity and life.

Graphite was first discovered at Lac Gueret in 2001 by Exploration Esbec Inc., a mineral exploration and production company based out of Sept-Iles, Quebec. The following year, Quinto Mining Corp. optioned a block of claims from Exploration Esbec, which now constitute the core of the current property.

Quinto conducted sporadic exploration of the property between 2002 and 2007, including trench and geological mapping, channel sampling, geophysical surveys, and drilling. However, very little work was carried out to develop the project.

In 2008, Quinto was acquired by Thompson Iron Mines and, in 2011, Cleveland-Cliffs (NYSE: CLF), then called Cliffs Natural Resources Inc., acquired Thompson.

Mason acquired the property from Cleveland-Cliffs in 2012.

That same year the company completed a 163-hole infill drill program and then tested its first laboratory-scale concentration process on mineralised samples from the project.

From 2013-2014, Mason completed an 86-hole 13,418-metre drilling campaign.

Mason Graphite conducted additional metallurgical work on core samples from 2014-2015, with the first pilot test performed on a bulk sample in 2014.

In 2015, Mason started its “first transformation” by developing the deposit and mine concentrator.

Detailed engineering work for the mine was started in 2017, and the company purchased the main processing equipment for the concentrator, located in Baie-Comeau, 285 km to the south of Lac Gueret, in 2018.

Although the detailed engineering design work is 75% complete, said L’Heureux, it has been put on hold due to the currently oversupplied market of cheap graphite from China.

But he is optimistic, like many industry analysts, that the price of graphite will increase over the next few years as the use of energy storage technologies ramps-up and the demand for graphite outstrips current supply.

In 2018, the company released an updated feasibility study (FS), which outlined an open-pit mine producing 51,900 tones of graphite concentrate a year over a mine life of 25 years.

The study pegged capital costs at C$258.2 million with an after-tax payback period of about four and a half years. Operating costs were estimated to be C$627.3 million over the life of the mine for an average production cost of C$483.77 per tonne of graphite concentrate.

The FS, which used an average graphite concentrate price of $1,933 per tonne, forecast an after-tax net present value of C$278 million, at an 8% discount rate, and an after-tax rate of return of 21.7%.

The study was based on an updated mineral resource estimate for the project of 65.5 million measured and indicated tonnes grading 17.2% graphite for 11.2 million tonnes contained graphite. Inferred resources total 17.6 million tonnes grading 17.3% graphite for three million tonnes graphite.

“The high production grade of the ore means the production and operating costs are low,” L’Heureux said. “Even though the project would be profitable at the current market prices, at the moment, however, it is not enough to attract investors.”

The unfavourable market conditions, he said, have had a direct impact on the company’s share price, making it very difficult to develop the mine and concentrator without significant dilution. 

Until the graphite markets picks-up, the company is focusing on the “second transformation” in the process by developing value-added products using graphite purchased from the market for a range of applications, including insulation, carbon brushes, brake pads, and clutch facings in cars, flame retardants, paints, and lubricants.

“We are also continuing to optimise the coating process to improve yield further, improve product quality, and adapt the process to uncoated spherical graphite coming from external sources of graphite,” he said.

World Economic Forum tests blockchain for tracking carbon emissions

Most estimates of the carbon footprint of the mining industry’s value chain are currently based on industry benchmarks or non-standard unverifiable sensors, says Jorgen Sandstrom, World Economic Forum’s (WEF) head of mining and metals.

“This limits the [organisation’s] control and ability to improve the footprint,” he explained in an email to The Northern Miner. “Our vision is to enable verifiable visibility of the embedded emissions from the mine to the market, and the COT is a big step forward in delivering this vision.”

The COT, he said, is focusing on tracing carbon emission in the copper value chain and tracks GHG emissions from the mine to the smelter, and finally to the original equipment manufacturers. The platform, he said, has created a blueprint to track all essential metals from mine to market and back via recycling.

Developed in collaboration with industry experts and supported by Dutch blockchain technology company Kryha (or Holland-based instead of Dutch-based) and MMBI project manager and adviser Susan Joseph, the COT uses a distributed ledger technology to track carbon emissions, ensuring traceability of emissions from the mine to the final product, with a focus on end-to-end traceability.

The distributed nature of blockchain technology enables cross-enterprise collaboration, making it the ultimate networked technology.

“The COT demonstrates that participants within and across the value chains can collaborate and test practical solutions to sustainability issues that cannot be resolved by individual companies,” Sandstrom said.

“Having an industry approach enables us to focus on practical and viable ways to deliver on our vision,” he said. “We’re also exploring how to best work with other groups such as standards and assurance groups.”

The work follows the formation of the MMBI in October 2019, which was created in response to demands from stakeholders to develop mine-to-market visibility and accountability.

The MMBI is a collaboration between the WEF and mining and metals companies, including Anglo American (LSE: AAL), Antofagasta Minerals (LSE: ANTO; US-OTC: ANFGY), Eurasian Resources Group (TSXV: EMX; NYSE: EMXX), Glencore (LSE: GLEN), Klockner & Co, and Minsur.

The initiative aims to build responsible sourcing and sustainability practices into the industry by accelerating an industry solution for supply chain visibility and promote environmental, social, and governance requirements that use blockchain.

Commenting on the COT, Benedikt Sobotka, CEO of Eurasian Resources Group and co-chair of the Global Battery Alliance, said: “We believe that enhanced collaboration around blockchain technology is necessary to improve supply chain transparency and reporting on carbon emissions.

“The MMBI’s custom-built blockchain solution will allow customers to verify the environmental impact of the products they use, and we are excited to have entered the next phase of the platform’s development,” he added.

The consortium is currently testing several hypotheses about the future of the platform, Sandstrom said.

“Feedback sessions with industry stakeholders will be scheduled in early 2021,” he said. “Those sessions will help the group refine the vision and set the framework for the next phase.”

Anti-mining activists attack Curimining worker in Ecuador

A group of anti-mining activists attacked a worker that leads community relations for Curimining, the Ecuadorian company in charge of developing the Curipamba copper-gold project, held by Canada’s Adventus Mining (TSX-V: ADZN) and Salazar Resources (TSX-V: SRL).

The worker was attacked as he was entering the Las Naves Municipal Council, where he was to present documentation related to Curimining’s activities in this region of central Ecuador. The Council was to debate a new land use development plan.

Ministry of Energy and Nonrenewable Resources issued a communiqué deeming the violent actions as “politically motivated”

The incident took place on December 24, but was made public a few days later when the Ministry of Energy and Nonrenewable Resources issued a communiqué informing of the situation, deeming the violent actions as “politically motivated” and asking those who oppose mining projects to engage in peaceful dialogue. 

“It is important to point out that national and foreign mining companies operate under a mining title in Ecuador. Besides, the National Government works incessantly, in an inter-institutional fashion, in the development of a responsible mining sector that is compliant with the law and that sanctions illegal activities,” the Ministry’s statement reads. 

Curimining used social media to express the company’s position regarding the attack.

“We are deeply sorry that our coworkers had to go through this shameful experience, exposing their lives in front of a group of people that claim to defend Pachamama while fearlessly attacking human lives,” Curimining’s release reads.

Besides carrying out activities with the local communities, Curimining is also in charge of exploration and project development at Curipamba, a property that covers 21,537 hectares and includes the advanced high-grade copper-gold El Domo deposit. 

El Domo is a flat-lying tabular shaped VMS deposit, with mineralization beginning at 30 metres from surface and dimensions of approximately 800 x 400 metres. 

In 2020, Adventus acquired surface rights covering 100% of the land overlying the estimated mineral resources and proposed open-pit and underground mines.

As of June 2020, the Toronto-based miner had funded over $20 million in exploration and project development activities towards the earn-in requirement it signed with Salazar in 2017. 

A feasibility study for Curipamba is expected to be completed by the fourth quarter of 2021.
