Far North Snapshot: Eight companies venturing into the remote north for minerals

Although there are many examples of fabulously rich gold, diamond and base metals mines that have been developed in the Far North, the mineral potential of the northern reaches of Canada, the U.S., and Europe remains largely untapped. Here are eight exploration, development and mining companies active in the Arctic and near-Arctic.

BMC Minerals

Vancouver-headquartered BMC Minerals, wholly owned by privately held, U.K.-based BMC Ltd., is developing the Kudz Ze Kayah base metals project in southeast Yukon. The polymetallic project was recognized by BMC as a development opportunity in 2014 and acquired the following year from Teck Resources (TSX: TECK.A/TECK.B; NYSE: TECK).

The region is known to contain significant volcanogenic massive sulphide deposits and large sections of ground within the property remain underexplored. The company is mainly focused on the ABM Zone, which hosts probable reserves of 15.7 million tonnes grading 5.8% zinc, 1.7% lead, 0.9% copper, 138 grams silver per tonne and 1.3 grams gold.

Mining of the ABM deposit is anticipated primarily by open pit methods with a small underground mine proposed to exploit the deeper section of the Krakatoa Zone, which was discovered by BMC during field work following the acquisition of the property.

A low strip ratio of 6:1 in initial open pit mining will facilitate rapid capital payback in the early stages of the nine-year mine life, while an average 10:1 strip ratio is anticipated for the life-of-mine operation.

A prefeasibility study (PFS) completed in 2017 confirmed that Kudz Ze Kayah is technically and economically viable. The PFS was followed up by a feasibility study that was completed in June 2019 and updated in November 2020.

The Yukon Environmental and Socio-Economic Assessment Board (YESAB) issued a final screening report for the project in October 2020, which was positive, but listed 30 mitigation measures and six monitoring measures. Both levels of government have been consulting with the Kaska First Nation on the terms and conditions. Once a decision document from the federal and Yukon governments is in hand, the company will start the permitting and licensing process, which it anticipates will take two years.

BMC plans to produce three concentrates to be transported using an existing 905-km road network from the mine site to the port of Stewart, British Columbia, for sale and transport to Canadian and export markets. The peak construction workforce is estimated to number 670 with 320 employed once the mine is in operation.

According to the updated feasibility, the project carries a preproduction capital cost of $376 million and will produce 7.8 million oz. of silver, 56,500 oz. of gold, 235 million lb. of zinc, 32 million lb. of copper and 56 million lb. of lead each year in concentrate during steady-state operations. The study estimated Kudz Ze Kayah’s after-tax net present value at $617 million, based on a 7% discount rate, and its internal rate of return at 45.9%.

Mawson Gold

Mawson Gold (TSX: MAW; US-OTC: MWSNF) is a Vancouver-based exploration company with properties in Finland and Australia. The company’s 100%-owned Rajapalot gold-cobalt project covering 179.9 sq. km, is located just south of the Arctic Circle in Finland’s Lapland region.

In August 2021, the company reported an inferred mineral resource of 10.9 million tonnes grading 2.5 grams gold per tonne and 443 ppm cobalt (or 3 grams gold equivalent) for 887,000 oz. of gold (1 million oz. of gold equivalent). The updated resource estimate increased the project’s gold grade by 19% and contained gold ounces by 47% compared to a previous September 2020 estimate.

The Rajapalot project forms part of Mawson Gold’s larger 100%-owned, 100-sq.-km Rompas-Rajapalot Finnish project area.

Mawson’s 2021 winter exploration program included 84,507 metres of drilling at Rajapalot with an average depth of 155 metres. The updated resource was based on a total of 330 holes totalling 72.8 km and drilled to an average depth of 250 metres. (The 2020 resource estimate was based on 257 holes totalling 53.8 km at an average depth of 209 metres).

Mawson is working on its first-ever preliminary economic assessment for Rajapalot, which is due out in the third quarter.

“The commencement of a maiden PEA marks an important step towards Rajapalot joining its developer peers,” said Mawson Gold CEO Ivan Fairhall in a release. “This is the first time the favourable geology, metallurgy and location of our million-ounce Rajapalot inferred mineral resource estimate will be articulated to the market as a coherent business case.”

Mawson’s wholly-owned Finnish subsidiary, Mawson Oy, has received two rounds of funding from the Finnish consortium’s BATCircle program aimed at promoting the discovery and development of battery metals. The company was granted €500,000 ($527,000) as part of BATCircle1.0 and an additional €795,000 ($838,000) in funding as part of BATCircle2.0 to further study cobalt extraction, marketing and residues management.

The company has engaged SRK Consulting Finland to develop open pit and underground designs and schedules, as well as mine infrastructure and associated cost estimates.

Mawson has an interest in several properties in Australia through Southern Cross Gold, a company it incorporated in July 2021 and that it plans to list on the Australian Securities Exchange this year.

Nighthawk Gold

Nighthawk Gold (TSX: NHK, US-OTC: MIMZF) is a Canadian-based gold exploration company that holds more than 930 sq. km of a district-scale land position within the Indin Lake Greenstone Belt, located approximately 200 km north of Yellowknife in the Northwest Territories.

The land package lies along the West Bay-Indin Lake Fault Zone, a regional structure that extends over 200 km from Great Slave Lake to areas north of the Indin Lake Greenstone Belt. The fault zone hosts the Giant and Con gold mines that produced 13 million oz. of gold, and the Colomac mine that produced 527,908 oz. gold. Company management likens the potential of the structure to other fault zones such as the Destor-Porcupine Fault in the Timmins camp.

The Colomac Main Deposit, one of the historic open pit gold mines within the property, was acquired by Nighthawk in 2012. Nighthawk has advanced Colomac Main, four other adjacent deposits and four other higher-grade satellite deposits – Kim, Cass, Damoti and Treasure Island – that lie between 11 and 28 km from Colomac Main.

In March, the company reported an updated resource estimate that increased open pit indicated resources by 121% to 2.1 million oz. of gold in 46.4 million tonnes averaging 1.38 grams gold per tonne. The open pit inferred resource climbed by 1,400% to 601,000 oz. gold in 7.8 million tonnes grading 2.39 grams gold.

A 2022 exploration drilling program set to begin in May will focus on expanding near-surface, high-grade open pit mineralization at the Kim, Cass, Damoti, Treasure Island and other targets. Nighthawk’s camp is capable of accommodating up to seven drills and can be accessed by ice road and a 5,000-ft. airstrip.

The company has a current market cap of approximately $10.8 million.

Sabina Gold & Silver

Vancouver-based Sabina Gold & Silver (TSX: SBB; US-OTC: SGSVF) is advancing its 100%-owned Back River gold project, an 80-km long belt with a series of gold deposits in banded iron formation located in southwestern Nunavut, approximately 520 km northeast of Yellowknife. The project was purchased from Dundee Precious Metals (TSX: DPM) in 2009.

According to an updated feasibility study completed in 2021, the company’s Goose project, the first mine it hopes to develop in the district, will generate an after-tax internal rate of return of 27.7% and a net present value (at a 5% discount rate) of $860 million. A rapid payback of 2.3 years is expected, based on a gold price of $1,600 per oz. The initial capital requirement was estimated at $610 million, with life of mine sustaining capital and closure costs at $326 million.

The updated feasibility study was based on an initial processing rate of 3,000 tonnes per day with an expansion to 4,000 tonnes per day by the end of year two. The mine plan envisions average gold production of 287,000 oz. gold per year for the first five years and 223,000 oz. gold per year over a 15-year mine life at a cash cost of $679 per oz. gold and all-in sustaining costs of $775 per ounce. Approximately half of the mine production is expected to come from open pits with underground production scheduled each year of operation.

A total of 18.7 million tonnes are to be milled over 15 years for a total of 3.3 million oz. gold with a life-of-mine average grade of 6 grams gold per tonne and average metallurgical recovery of 93.4%.

Open pit and underground proven reserves at the Goose, Echo, Umwelt and Llama deposits total 8 million tonnes at 5.54 grams gold per tonne, with probable reserves at 10.7 million tonnes grading 6.29 grams gold. Cut-off grades range between 1.6 g/t gold and 4.1 g/t gold.

Sabina reports comprehensive project financing of more than $550 million is in place, consisting of a senior secured debt facility, a gold prepay facility and a private placement from Orion Mine Finance and a gold stream arrangement and private placement with Wheaton Precious Metals (TSX: WPM).

The project is in receipt of all major permits and authorizations for construction and operations. The company has signed a 20-year renewable land use agreement with the Kitikmeot Inuit Association and has committed to employment and business opportunities with its Inuit stakeholders. A 3,500-metre surface exploration drill program was conducted in March and April.

“We look froward to receiving the results of this spring’s drilling program as we continue to evolve and develop the resource potential at the 8 km long Goose Gold Complex,” said Bruce McLeod, president and CEO. “As we have demonstrated in past drilling campaigns, the gold endowment at Goose is exceptional and we remain committed to an exploration and resource growth and optimization strategy that we believe will add considerable value to the project as we progress towards production.”

Sabina Gold & Silver has a market cap of $623 million.

Trilogy Metals

Vancouver-based Trilogy Metals (TSX: TMQ; NYSE-AM: TMQ) is a 50% owner of the Upper Kobuk Mineral Projects (UKMP) consisting of a 1,814-sq.-km land package in the Ambler Mining District of northwest Alaska. In February 2020, a 50:50 joint venture was concluded with South32 Ltd. (LSE: S32; ASX: S32), a global diversified metals and mining company with a market cap of $10 billion that was spun off from BHP (NYSE: BHP; LSE: BHP) in 2015. Trilogy contributed all of its UKMP-associated assets to the jointly-owned Ambler Metals LLC while South32 contributed $145 million.

The UKMP hosts the feasibility-stage Arctic copper-zinc-lead-gold-silver volcanogenic massive sulphide project, described as one of the highest-grade copper deposits in the world with an average grade of 5% copper equivalent. It also hosts the Bornite copper-cobalt carbonate replacement project, located 25 km southwest of the Arctic project.

A February 2020 feasibility study on the Arctic project, located 470 km northwest of Fairbanks, Alaska, reported a base case after-tax net present value at an 8% discount rate of $860 million and an internal rate of return of 27.1%.

The initial capex for the open pit, 10,000-tonne-per-day operation was estimated at $704 million with sustaining capital of $88.5 million for total capital expenditures of $860 million over a 12-year mine life.

The study projected average annual payable production of more than 155 million lb. of copper, 192 million lb. of zinc, 32 million lb. of lead, 32,000 oz. of gold and 3.4 million oz. of silver.

The less-advanced Bornite deposit hosts an indicated resource of 955 million lb. of copper in 41.7 million tonnes grading 1.04% copper. Inferred resources include 5.3 billion lb. of copper in 144.1 million tonnes grading 1.68% copper, and 88 million lb. of cobalt in 185.8 million tonnes at 0.021% cobalt.

The JV is seeking approval for a 340-km industrial access road to the site, which would connect the project with existing road and rail infrastructure for the transport of concentrate to the Port of Anchorage, Alaska. In March, the right of way permits previously issued to the Alaska Industrial Development and Export Authority (AIDEA) for the project were suspended by the U.S. Department of the Interior, which wants additional work completed on the Final Environmental Impact Assessment. While it awaits a judge’s decision on the permitting, the company says it will go ahead with a $27 million, 10,000 metre drill program this summer at Arctic.

Victoria Gold

Victoria Gold (TSX: VGCX; US-OTC: VITFF) is the 100% owner of the Eagle gold mine in central Yukon. The open pit, heap-leach operation is located on the company’s 555-sq.-km Dublin Gulch property in the Tintina Gold Belt, 85 km by road northeast of Mayo and 491 km north of Whitehorse.

The company acquired the property in 2009, beginning drilling and other exploration work the same year. First gold was poured in the third quarter of 2019 and commercial production was declared July 1, 2020.

The company reported annual gold production of 164,220 oz. of gold in 2021, an increase of more than 40% over 2020 production. It aims to increase production to 250,000 oz. in 2023. Victoria Gold reported revenue of $276 million and net income of $84 million for 2021.

The Eagle mine has grid hydro power, year-round road access and a 300-person, all-season, well-equipped camp. Mine employees work a fly-in/fly-out rotation using a commercial air strip 80 km away, near the village of Mayo.

The Dublin Gulch property also hosts several other targets, including the Raven deposit for which Victoria Gold has budgeted $15.5 million for 25,000 metres of exploration drilling this year.

The Eagle and nearby Olive deposits contain proven and probable reserves of 2.7 million oz. of gold in 123 million tonnes of ore grading 0.67 gram gold per tonne. Measured and indicated resources are estimated at 191 million tonnes averaging 0.65 gram gold containing 4 million oz., inclusive of proven and probable reserves. Inferred resources add 24 million tonnes averaging 0.61 gram gold per tonne for 500,000 ounces.

Victoria Gold president and CEO John McConnell and the Victoria Gold team were the recipients of the Association for Mineral Exploration’s (AME) 2021 E.A. Scholz Award for excellence in mine development in British Columbia and the Yukon Territory.

Victoria Gold has a market cap of $746 million.

Western Copper and Gold

Western Copper and Gold (TSX: WRN; NYSE: WRN) is developing the Casino project, a porphyry copper-gold-molybdenum deposit located in west-central Yukon, 300 km northwest of Whitehorse. The property lies within the Whitehorse Mining District and consists of 1,136 full and partial quartz claims covering an area of 211.3 sq. km, and 55 placer claims encompassing 4.9 sq. km. Rio Tinto (NYSE: RIO; LSE: RIO) has a 7.8% stake in the company, which it acquired last year via a $19.9 million investment.

Based on a 2021 preliminary economic assessment, an open pit mine at Casino could feed a 120,000-tonne-per-day concentrator, and a 25,000-tonne-per-day gold heap leach facility for 25 years with a preproduction capital investment of $2.5 billion. The study projected a $2.2-billion after-tax net present value (using an 8% discount rate) and a 19.5% internal rate of return.

On-site processing facilities will produce a copper-gold concentrate, a molybdenum concentrate and gold and silver doré bars. A conventional open pit, truck and shovel operation is proposed with processing primarily by conventional milling to produce a concentrate. Some ore will be heap leached for gold recovery. Concentrate will be shipped to the Alaskan port of Skagway, 560 km from the mine site. An environmental and socio-economic project proposal was submitted for Casino in January 2014.

In February 2016, the Yukon Environmental Socio-economic Assessment Board determined that the project requires a panel review. A feasibility study is expected to be submitted by June of this year and an environmental and socio-economic statement is scheduled for submission in the second quarter of 2023. Since an initial feasibility study in 2013, changes have been made to the project to reduce the amount of water that would be held in the tailings impoundment to alleviate concerns about the size of the tailings impoundment and any potential failure.

Western Copper and Gold reports a resource of 7.6 billion lb. of copper and 14.5 million oz of gold in the measured and indicated category in 2.4 billion tonnes grading 0.14% copper and 0.19 gram gold per tonne. Inferred resources add 3.3 billion lb. copper and 6.6 million oz. of gold in 1.5 billion tonnes at 0.1% copper and 0.14 gram gold.

Western Copper and Gold has a market cap of $342.8 million.

White Gold Corp.

White Gold Corp. (TSXV: WGO; US-OTC: WHGOF) is a Canadian gold exploration company operating in the prolific White Gold District south of Dawson City in northwest Yukon, site of the historic Klondike Gold Rush. The district is an emerging gold camp with more than 20 million oz. of historic placer gold production and 20 million oz. of defined gold resources.

White Gold owns a portfolio of 21,111 quartz claims across 31 properties covering more than 4,200 sq. km, accounting for 40% of the district. Its flagship Golden Saddle and ARC deposits collectively contain indicated resources of 1.1 million oz. within 15.6 million tonnes averaging 2.28 grams gold per tonne, and inferred resources of 402,100 oz. within 9 million tonnes at 1.39 grams gold with mineralization remaining open along strike, down-dip and down-plunge. Its VG deposit, acquired in March 2019, contains an inferred resource of 267,000 oz. gold in 5.3 million tonnes grading 1.62 grams. Most of its resources are near surface and, therefore, conducive to open pit mining.

Exploration highlights include multiple high-grade gold intervals such as: 72.81 grams gold per tonne over 6.1 metres from 10.7 metres depth, including 136 grams gold over 3.1 metres; and 23.44 grams gold over 24.4 metres from surface.

Regional exploration work has produced several new discoveries and prospective targets on the company’s claim packages, including its Ryan Surprise, Betty Ford and Ulli’s Ridge targets. Nearby gold projects include Newmont’s Coffee gold project and Western Copper and Gold’s Casino copper project.

Strategic shareholders include Kinross Gold (TSX: K; NYSE: KGC) with 17% ownership, and Agnico Eagle Mines (TSX: AEM; NYSE: AEM) with 19.9% ownership following the closing in December 2021 of a non-brokered private placement for aggregate gross proceeds of $7 million. The company is planning its 2022 drill program, which will be 100% funded by its partners.

“We are very grateful for the continued support of Agnico and our other shareholders and are now fully financed for what we expect to be another exciting and impactful exploration program in 2022,” said White Gold CEO David D’Onofrio. The company was co-founded by prospector Shawn Ryan, who made the Coffee discovery.

White Gold has a market cap of $64.6 million.

Apple, Tesla, Intel could be using conflict minerals due to faulty scheme

Several of the world’s largest companies including Apple, Tesla and Intel may be using conflict minerals from the Democratic Republic of Congo (DRC) in their products as they rely on a certification scheme accused of helping “launder” irresponsibly mined metals.

According to the latest report of Global Witness, an international non-profit that challenges power abuses, several firms that use the International Tin Association’s Tin Supply Chain Initiative (ITSCI) scheme are allegedly at fault of fuelling conflicts.

The ITSCI program, launched after the 2010 Dodd Frank legislation, requires US companies to vet their supply chains to avoid using minerals tied to human rights abuse and guerillas.

Global Witness’ report suggests the scheme is not fulfilling its mission as its researchers gathered “compelling evidence” of ITSCI enabling the laundering of ore from mines controlled by militia or using child labour.

The same certification has allowed the trafficking of conflict minerals, used to finance armed clashes, according to Global Witness.

In one mining area, the investigation found that up to 90% of minerals introduced into ITSCI during the first quarter of 2021 did not come from operations certified as meeting security and human rights standards.

Worsening the situation, Global Witness said, a significant portion of those minerals were linked to conflict and human rights abuses. A similar situation was detected at another ten locations.

The evidence suggests that the scheme many global companies rely on to stop conflict minerals from entering their supply chains is “failing spectacularly”, Alex Kopp, campaigner at Global Witness, said in a statement.

The report claims ITSCI a has downplayed and ignored these issues, as it is run by two powerful tin and tantalum associations — the International Tin Association (ITA) and the Tantalum-Niobium International Study Center (TIC).

Both organizations represent many of the major buyers of the “3T” minerals — tin, tantalum and tungsten in the region, the study says.

“As long as ITSCI is overseen by those who stand to gain from access to tin, tantalum or tungsten, it will continue to fail,” Kopp said.

This is not the first time top tech companies are said to be linked to conflict minerals. Five of the world’s largest — Tesla, Apple, Alphabet, Microsoft and Dell — were singled out in December in a lawsuit accusing them of being complicit in the death of children in Africa forced to mine cobalt.

More than 40 million people have been estimated to be captive in modern slavery, which includes forced labor and forced marriage, according to Walk Free and the International Labour Organization.

In response to questions from Global Witness, ITSCI denied any supply contamination as well as links to armed conflict and child labour.

Electric vehicles giant Tesla and other market actors are involved in testing alternative schemes, such as Re|Source, a solution to trace responsibly produced minerals from mine to EVs. Volkswagen is also working on improving working conditions in the mines in the DRC.

Trading house Trafigura inked last year a supply deal with Entreprise Générale du Cobalt (EGC), a new DRC-owned company, created to help control artisanal supplies and boost government revenue through price controls.

Time to dig deeper

Evidence gathered by Global Witness also suggests that Swiss businessman Chris Huber, who is under criminal investigation for war crimes in DRC, used the ITSCI scheme to launder smuggled minerals through at least three companies based in Rwanda.

Business linked to him and his partner, former TIC president John Crawley, also appear to profit from hundreds of tonnes of trafficked coltan, which are likely laundered through ITSCI in Rubaya area in the DRC, the report says.

Over the past two years, some mining companies have abandoned ITSCI and joined other certification schemes, such as the Better Sourcing programme, which was implemented by responsible-sourcing group RCS Global.

When leaving ITSCI in 2019, Congolese coltan miner Société Minière de Bisunzu (SMB) complained about ITSCI raising costs.

Other companies have also complained about the scheme’s increasingly burdensome costs, but haven’t abandoned it as they worry they will not be able to sell their minerals without the certification.

Pressure on ITSCI to lower costs has increased in the past two years with the surge of responsible sourcing alternatives seek to use blockchain, the technology behind cryptocurrency bitcoin, to help to track minerals and guarantee they are clean.

The extraction of other metals, particularly of cobalt, in the DRC has been linked to human rights abuses, corruption, environmental destruction and child labour.

As cyber threats rise, how vulnerable are mining companies?

Rising geopolitical risks ever since Russia launched its attack on Ukraine, combined with a massive digital transformation in the mining sector in recent years to boost efficiency, has vastly increased the need for companies to update and invest in their cyber security systems, analysts and mining executives say.

Victoria Gold (TSXV: GCX) warned investors in its annual report last month that the military invasion of Ukraine could lead to “heightened cybersecurity disruptions and threats” in 2022, even though the company doesn’t have any operations in Russia or Ukraine.

In the same month, Endeavour Mining (TSX: EDV; LSE: EDV) listed cyber security as one of its principal risks and said that companies were becoming “more vulnerable to cyber threats” due to the increasing reliance on digital technology.

“Although Endeavour invests heavily to monitor, maintain, and regularly upgrade its systems, there remains a risk that we may be unable to prevent, detect, and respond to cyber-attacks in a timely manner,” it said in its annual report.

According to Ernst & Young’s Global Information Security Survey published in mid-2021, about 55% of mining executives are worried about their ability to manage a cyber threat with nearly 70% witnessing an increase in the number of disruptive attacks in the previous 12 months. Almost half of the respondents said that the industrial control systems were most frequently attacked.

Analysts say that the impacts of these attacks can range from company stocks being shorted or the lives of workers being put in danger when crucial operating systems are hacked to something as simple as assay results getting delayed.

For instance, in the last five months British Columbia-based PJX Resources (TSXV: PJX) and Getchell Gold (US-OTC: GGLDF) in Nevada reported delays in receiving their assays as the Bureau Veritas Laboratory in Nevada was recovering from a cyber-attack that hit the company in November last year.

Nadine Miller, an engineer who has worked in mining for over two decades and is currently vice-president of project development at JDS Energy & Mining, notes that the industry has a tradition of being late adaptors to new technologies and is now also lagging behind in cyber security.

“We are always in a race to be the first ones to be last in new technologies,” Miller told The Northern Miner, adding that mining companies generally don’t want to be early adaptors of any technology. “There are a few that will do it,” she said, adding they are usually larger companies.

Miller says that while the mining industry has done a good job in securing its information technology (IT) systems, which include network infrastructures, file shares or employee laptops and computers, the operational technology (OT) – which, for example, involves systems responsible for process plants, refineries, heating or ventilation in underground mines – are not secure.

Bryan Tan, an Associate partner at EY’s cyber security practice says that ransomware, a type of malicious software designed to block access to a computer system until a sum of money is paid, is one of the “key threats” in the industry right now.

“A lot of organizations… put the OT systems on the same network as the IT systems,” he told The Northern Miner. “That starts to spread on the environment in the IT side, but because it can touch the OT systems, it can potentially impact those as well. From more of a business impact, your OT comes to a standstill and that may lead to life-threatening issues as well,” he explained.

AI technology

To tackle OT-related issues, JDS and Miller are promoting a new technology, based on artificial intelligence machine learning (AI/ML), that they say can detect abnormalities in industrial control systems.

Miller’s JDS colleague Joe Weiss, a global expert on industrial control systems, says that mining companies, like firms from other industries, depend upon sensors to run their operations. These can be hacked when connected to the web, a network, Bluetooth access via mobile devices, or simply a handheld calibration unit, and end up providing faulty signals that could, for instance, overheat or cool systems and damage them.

“The JDS technology can tell you if the sensors are not doing exactly what they should be or if they are inoperable,” explains Weiss. “The sensors are the input to everything you do… the technology is making sure that the input going to the brain, is actually coming from the sensors and that we know how good the sensors are. And if (they’re) not, when we need to do maintenance for the sensors.”

To further explain the role that sensors play, Miller and Weiss referred to the Taum Sauk Hydroelectric Power Station in the United States which overtopped in 2005 when water continued to be pumped from the lower reservoir even after the upper reservoir was full. While no deaths were reported during the event that wasn’t related to cyber-threat, the flood destroyed many structures in a park.

According to Weiss, the attachments holding the sensors at Taum Sauk dam failed. Although they were detached from the wall and ended up at a different location, they continued to work. “They inadvertently told the system that the level was low,” said Weiss. As a result, the pumps were instructed to fill the reservoir. The JDS technology would have noted the change in the level and instructed the operator to check the problem, which is what makes the tool unique, he added.

The technology was installed in a refinery project this year, Miller said (the name of the company was not disclosed). Aside from providing protection against hacking, it also helped in detecting operational anomalies once the AI/ML went live, she said.

“While the AI was learning their system, one of their engineers figured out that the controllers in the circuit was not working. We weren’t monitoring the controllers. But he realized that there was a problem with the controllers because the AI/ML was learning and the AI was flagging anomaly in the data,” said Miller.

Investment needed

EY’s Tan believes that the mining industry has “moved forward” and is a lot more willing than before to improve its cyber security environment. But he also says that the industry needs to put more money into these initiatives and ensure that IT teams build stronger relationships with different parts of the business.

According to EY’s survey, cybersecurity teams are struggling to build close relationships across the business — especially with teams that oversee the most critical systems and operational data.

“The problem is that many chief information security officers came up through IT and, today, there is a paradigm clash between IT and OT,” the survey said. “On one hand, you’ve got engineers focused on availability and safety, on systems that are potentially decades old. On the other, you’ve got a CISO (chief information security officer) urging them to patch the system straight away because of confidentiality and integrity concerns.”

Waybridge and the Port of Panama City partner to automate and digitize bills of lading

Waybridge, the supply chain operating system for raw materials, has announced an engagement with the Port of Panama City, one of the nation’s most critical gateways for the importation of metals. Situated on the Gulf Intracoastal Waterway the port has, since 2003, imported millions of tonnes of metals, primarily from Chile and Peru.

This collaboration is Waybridge’s first port engagement and will grant the port and its customers access to technology for added efficiency, transparency, and resiliency in their operations, the company said in a media release.

Through the electronic creation of bills of lading, Waybridge will digitize the process, unlocking the tracking of truck and rail shipments from port to final destinations, all within one interconnected, cloud-based platform.

Suppliers that ship material through the Port of Panama City will get access to shipping information as soon as a truck or rail car is loaded so they know instantly what has been picked up and can inform their customers as needed.

Port customers will also have the opportunity to track inbound truck and rail shipments after they leave the port, Waybridge said, and access shipping information prior to arrival to improve their planning and receiving processes.

The port will deliver a modern customer service experience to suppliers, consumers, and carriers, and create a more efficient operation by replacing manual document management with automated, digital communication to its customers.

Upgrading from siloed paper bills of lading to electronic bills of lading on an interconnected platform is beneficial for both suppliers and customers, allowing shipment information to be viewed by all parties in real-time on the Waybridge platform.

“With so much of the world’s copper traveling through the Port of Panama City each year, the impact this engagement will have on copper suppliers and customers across North and South America, as well as the entirety of the supply chain, is monumental,” Scott Evans, Waybridge CEO said in the statement.

“We see this as the first iteration of a long and fruitful relationship with the port as we continue to transform these previously fragmented tracking processes into a digitized, centralized system.”

Metso Outotec to install 100th anode casting system at Indonesian copper smelter

Metso Outotec will deliver its 100^th anode casting system to PT Smelting’s (PTS) copper smelter in Gresik, East Java, in Indonesia. Metso Outotec has been a frontrunner in the development of anode casting technology for several decades. Today, most of the world’s copper anodes are produced with Metso Outotec’s proprietary anode casting technology.

“The Gresik project marks a true milestone for us. The system to be delivered to PTS is one of the world’s largest twin-wheel anode casting shops with a guaranteed capacity of 120 t/h,” explains Sami Maaniittu, director of anode casting at Metso Outotec.

“We started the development and testing of automatic anode casting already in 1969 in Harjavalta, Finland. Before that, castings were made manually with controlled ladle tilting. The first anode weighing and casting machine was delivered to the U.S. in 1972, and a year later, the first complete anode casting shop was installed at the Harjavalta Smelter in Finland,” Maaniittu says.

Metso Outotec’s twin-wheel casting concept, paving the way for today’s industry standard, was developed in the 1990s. The optimized equipment design significantly improves casting capacity and provides more efficient use of floor space. The wheels are supported on large centre bearings and driven by double drive systems developed to eliminate the backlash effect in the wheel movement and to ensure even quality. The first twin-wheel anode casting systems were delivered in 1997. Since then, the twin-wheel has become the first choice of high-capacity anode casting shops.

Today, most of the anode casting shops supplied by Metso Outotec are fully electric without any hydraulic systems. Their high level of automation ensures premium anode quality with excellent weight accuracy and low reject rate combined with high capacity and availability.

In addition to full anode casting systems, Metso Outotec offers a variety of modular updates for the existing installations, including automation and services.

New copper-nickel ink for printed electronics resists oxidation

Japan’s National Institute for Materials Science (NIMS) has developed a new conductive ink for use in printed electronics with significantly improved resistance to oxidation.

In a paper published in the journal ACS Applied Materials & Interfaces, the researchers behind the development explain that after this ink is printed, it self-organizes into a conductive pattern with a copper core–nickel shell nanostructure.

According to the scientists, even though silver nanoparticle inks are currently the most commonly used in printed electronics, these inks are expensive and poorly compatible with soldering. Copper nanoparticle inks, on the other hand, are considered a viable, cheaper alternative but the issue with them is that they are extremely susceptible to oxidation, making them unsuitable for use in printed electronics.

Knowing this, the NIMS materials experts decided to conduct research on inks composed of complexes of organic amine ligands with a central metallic ion; these inks are stable in the air.

The team subsequently discovered that inks containing a mixture of different metallic complexes are capable of converting into different types of printed metallic patterns, including multilayered core-shell nanostructures and alloys, depending on the ink’s composition and other conditions.

Based on these findings, they created the new ink, which is composed of a mixture of copper and nickel complexes able to self-organize into a copper core–nickel shell nanostructure. Because its outer nickel layer is resistant to oxidation, this printed pattern is significantly more resistant to oxidation than patterns printed using conventional copper inks.

The new ink is also cheaper than the currently available silver nanoparticle inks. Moreover, the electrical resistivity of conductive patterns printed using this ink was no more than 19 μΩ·cm, indicating that the conductivity of these patterns is comparable to patterns printed using conventional metallic inks.

The scientists believe that the addition of fine copper powder to this ink will increase its ability to form thicker layers. Thus, they are currently designing this new ink formulation in collaboration with the developers of the copper powder: Sumitomo Metal Mining and Priways, which plan to release sample ink products in the near future.

SQM unveils largest electric fleet in Chilean mining industry

The largest electric fleet in the Chilean mining industry has been unveiled in Antofagasta by SQM in partnership with transport companies Viggo GrandLeasing, Transportes CVU and Andes Motor, as part of their sustainability plans to reduce their CO2 emissions.

Consisting of 34 fully electric vehicles, the fleet includes passenger buses, minibuses, vans, mobile solar checkpoints, and Chile’s first high-tonnage electric truck, making it the most diverse electric fleet in use across an entire mining operation in Chile.

With the launch of the new fleet, SQM said it is on track to achieve carbon neutrality in all its products by 2040 and follows up from the company’s announcement at the end of 2021 that it was joining the UN’s Race to Zero program.

SQM had already introduced Chile’s first high-tonnage electric truck to be used in large-scale mining onto an 86-kilometer route from the company’s Coya Sur plant in María Elena to the port of Tocopilla, saving approximately 3,840 tonnes of CO2 per year.

The vehicles were presented on the esplanade of the Huanchaca Ruins in Antofagasta, at an event that was attended by regional and community leaders.

“As a company we are proud to launch this fleet, contributing to the development of national electromobility and promoting the use of electric vehicles in the north of Chile, covering the regions of Antofagasta and Tarapacá, focusing on operational areas of our sites and on the transfer of all workers of SQM who live throughout the national territory,” said José Miguel Berguño, SQM VP, corporate services. “It is one more step in our robust Sustainability Plan that reaffirms our commitment to the environment, the communities surrounding our operations, and the environment.”

Lithium prices pause in April, but not a sign of “wider market correction”

Surging lithium carbonate and hydroxide prices in China took a breather in April, according to Benchmark Mineral Intelligence, but for chemical processors and battery manufacturers struggling to deal with prices doubling so far in 2022 the lull is unlikely to last.

The mid-April assessment by the London-HQed battery supply chain researcher and price reporting agency shows battery grade lithium carbonate (EXW China, ≥99.5% Li₂CO₃) down just under 1% over two weeks, but still within shouting distance of $80,000 a tonne. In April last year it was trading around $15,000.

Prices for lithium hydroxide, used in batteries with high-nickel cathodes, continued to rise in the first half of April. Hydroxide historically trades at a premium to carbonate and has been playing catch up – the gap is now down to around $400 a tonne, from a nearly $10,000 discount in February.

Benchmark says the slight downtrend in carbonate pricing “was not indicative of a wider market correction, but rather a temporary pause as a result of covid lockdowns in China, with expectations that prices will continue to increase in May if virus measures are eased.”

Evolving mining technology and the growing need to attract talent to the industry

With advancements in technology, an influx of new competitors within the mining technology space and an increase in large acquisitions globally, undoubtedly, it’s an exciting time to work within the mining industry.

Recent reports suggest a marked increase in the number of job postings within the mining sector, with significant growth predominantly in North America, Middle East and Africa. There have been rapid developments within mining and as a result, there’s a growing need to attract new talent and a variety of different skillsets to facilitate innovation and move towards a greener, safer, and more sustainable future in mining.

We spoke with Edward Bardo, Global Sales Director, Mining, Minerals and Metals – Aspen Technology who shared his thoughts on the impact of mining technology on the industry.

“The importance of sustainability in the mining industry is increasing. Mining isn’t something that is optional, it is something that must be done. If something is not farmed, it is mined, so driving a better image of sustainability in the industry is important and can be done through the implementation of digital technology across mining processes.”

Technology developments within mining

The mining industry has experienced huge developments contributing to increased efficiencies, production, and more sustainable processes predominantly down to the advancement of new mining technology. At CSG Talent we work with clients operating in the mining technology space with a wide range of automated and intelligent technologies readily available. The three predominant areas within mining technology with an increased need for talent are fleet management systems, mine planning software and drones.

Fleet management systems

Implementing fleet management software enables fleet managers within the mining sector to monitor their vehicles, equipment, and drivers, all from a remote location offsite. Utilising this type of software is hugely beneficial within mining as it allows businesses to locate and monitor the performance of vehicles, while also reducing the risk of accidents. With the opportunity for this software to be controlled remotely, it has a huge impact on productivity and safety due to less physical presence of staff on site. Leaders in fleet management systems include Modular and Hexagon, both of which are innovative and forward thinking organisations to work for.

Mine Planning Software

Mine planning software allows mining operators the opportunity to utilise fast, accurate and cost-effective tools in an efficient way. Mining software can be utilised remotely, allowing every element of mining to be managed and controlled from anywhere across the globe, making mining processes more efficient and allowing mining operators to add significantly more value. Some of the key players in this space are Datamine, Deswik, Micromine and Maptek who are leading the way with their mine planning software.

Drones

Large drones are used in mining for 3D terrain mapping, surveying, and inspection on site at mines. Drones have a great impact on increased safety on site, where previously, staff could be exposed to a potentially dangerous environment. The drones can carry out a risk assessment onsite, prior to any further action. Underground mines which historically had limitations with access and GPS are now being reached by drones which naturally expands materials available. A great example by Flyability, demonstrating the capability and effectiveness of utilising drones to inspect a high altitude mine is the Elios 2 inspecting a mine in the Andes Mountains.

Talent attraction challenges in mining technology

The global skills shortage is impacting the mining technology industry with organisations experiencing challenge attracting talent. There is a significant lack of awareness of the opportunities available within mining technology and the career paths available. There are also added concerns and preconceptions around the nature and safety of the work which can impact talent attraction.

Perceptions of a traditional industry and lack of awareness of opportunities

Lack of awareness of technology focused roles available within the mining industry means candidates have little exposure to potential roles and are not actively seeking opportunities. There is huge competition from global companies such as Google, Amazon, Tesla where tech-savvy professionals are inclined to reach out to or apply for tech roles. The mining industry is predominantly thought of as a labour intensive, hands-on role working in the mines so many companies are having to focus on their branding, image as an employer and how they are perceived to potential candidates.

Henrique Silva is a Senior Consultant Mining Engineer at Datamine, he shared his thoughts with us on perceptions of the mining industry:

“The interest from younger generations is not strong in geology and mining. The stigma that the mining industry is a ‘dirty industry’ which is not environmentally friendly needs to be changed. As an industry, we need to communicate the technical advancements better to attract more talent to the industry”

Lack of training and development opportunities

Many mining technology companies fail to offer adequate and appealing training and development opportunities for both new and existing staff. By investing in the resources that will support ongoing development of staff and the key skills needed to drive new technology, businesses will see the results across their organisation.

Increased competition attracting talent

With new mining technology organisations continually coming to market and companies looking to expand the spectrum of technology they offer, there is increased competition to attract talent with the right level of skills and experience. Historically, there would be one candidate with one potential job opportunity in the pipeline. In today’s candidate driven market there is now one candidate with on average six potential job opportunities available to them. This allows candidates the luxury of deciding which company is right for them and supporting their career goals.

Eddie Geisel, Founder of Prana Global Sales shared his thoughts on the impact of mining technology and the challenges this poses with talent attraction:

“Mining technology has allowed miners to have access to data in real time they previously didn’t have had access to, which empowers them to make data-driven decisions almost immediately. This leads to higher operating efficiency, less mistakes, and lower operating costs.

One of the biggest challenges is finding people who understand the mining domain and the specific problems that miners experience between different phases of the mining value chain, and how technology can help them solve these problems.

The industry is gearing towards automation; however, this transition will take time. A fundamental change in the industry is mining technology companies consulting with mines to decide where to start on their journey towards automation. Technology companies will need to position their sales teams to effectively define the mining challenges of their clients to ensure new mining technology can truly add value to the mining operation.”

Companies are crying out for a new type of skill set in the mining industry, candidates who can operate, understand, and interpret the advanced technology available.

Attracting new talent to mining technology

Widen the pool of candidates

Organisations need to ensure they are proactive in sourcing and attracting technology skilled candidates who have little exposure to the industry. Many roles within mining technology can operate remotely; for example, a truck digging in a mine in Chile, can be operated by staff based in Canada. The scope for remote operation continues as mining technology advances and this is hugely exciting for candidates in this field. Geography constraints and small candidate pools can be eradicated as an issue for many mining technology roles, with the possibility of expanding the talent pool globally for roles that can be carried out remotely. This allows organisations access to more skilled candidates than might be possible in a commutable distance to a mine.

Employer branding and appeal

Focus on the development of employer brand and raise awareness of the types of career options available within mining and mining technology. Evaluate your culture, benefits packages and your full hiring and attraction processes. Consider alternative means to attract the skilled talent within technology to appeal more than the competition. At CSG Talent we work closely with clients for talent and market mapping to allow them to build knowledge of the competition, brand perceptions and explore ways to enhance their employer brand.

Working with an expert recruiter in mining technology

At CSG Talent we are focused on building strong, long-lasting relationships with both our clients and candidates within mining technology. We have regular communications, a huge network of experts in this field and keep abreast of latest developments and market insights. This enables us to effectively guide, advise and support clients with their business growth and talent attraction strategies.

We focus on latest trends, overcoming challenge, and ensuring clients appeal to candidate needs and motivations. In today’s market, facilitating a positive candidate experience is essential. CSG Talent work in partnership with our clients to ensure a seamless and effective hiring process, managing the expectations of all parties and ultimately acting as a brand ambassador and extension of the business.

Christina Theoklitou-Panagiotou, Managing Consultant and Expert Recruiter in OEMs, Mining Technology and Processing shares her thoughts:

“Now more than ever we need to focus our efforts on attracting talent to the industry, and the use of specialist head-hunters is going to be vital to that. Here at CSG Talent, partnered with our specialist consultants we work collaboratively with our mining dedicated research team who not only support our headhunting offering but also lead our Talent Strategy Service. This includes talent mapping & pipelining, salary benchmarking, and branding, this improves our service offering to both clients and candidates which will result in meeting recruitment plans, both long and short term. “

Mining is the industry most at risk for fraud – report

The mining industry has seen the biggest overall increase in fraud cases, climbing 30% over the last 4 years, from 20 cases to 26, a new report reveals.

The research, conducted by SEON, reviewed the Association of Certified Fraud Examiner’s Report to the Nations and compared the figures to the report 4 years prior, to identify which industries have suffered the largest increase in fraud.

The mining industry also suffered the largest median loss —$475,000 — of all the industries examined. Despite the increases in fraud cases in the industry, this median financial loss has decreased by 5% in the last four years, SEON reported.

Fraud in the mining industry can take many forms, from inventory theft to improper asset evaluations. The four main types of mining fraud are: environmental, forestry, occupational and reserves or resources reporting.

SEON reported that despite the increase in reported fraud cases and the large median financial loss, the median financial loss in mining fraud has decreased in the last four years – by 5%.
