Glencore postpones dividend payment decision due to covid-19 related risks
Miner and commodities trader Glencore (LON: GLEN) has deferred making a decision on whether to go ahead with the proposed 2020 cash distribution as risks associated to a global recession and massive demand shock looms.
The Swiss-based company had announced plans to reward investors with $2.6 billion in cash distribution this year, or $0.20 per share. Instead, it said it was taking “prudent” action to protect and strengthen its capital structure amid the current period of heightened uncertainty.
Glencore warned that, while there were currently no risks of material production disruption owing to the coronavirus pandemic, the situation could rapidly change due to uncertainties.
The firm also extended its current credit facilities to protect its capital structure and generate free cash flow.
Today’s announcement makes of Glencore the first major diversified miner to take such a step in respect of capital returns. Others such as BHP, Rio Tinto and Anglo American, have not commented on changes to dividends or disruption to other kinds of capital return.
A decision on resuming the payout would be made later in the year, Glencore said.
The news come at a difficult time for the company. It reported in February its first annual net loss since 2015, as it had to take a $2.8 billion impairment charge to reflect the closure of its African copper business.
It also follows an audit overview of the firm’s 2019 annual report in with examiners found potentially “relevant facts” that may help authorities progress on the multiple, but separate alleged corruption and bribery investigations targeting the Swiss company.
Last week, it halted a number of smaller mines due to government restrictions to curb the spread of the coronavirus
While today’s announcement will be painful for investors, analysts believe it reflects a situation that is not nearly as bad as 2015, when top miners, particularly Glencore and Anglo American, were frantically trying to pay down debt and their share prices nosedived.

Mining Association applauds 75% wage subsidy announced by Canadian government
The Mining Association of Canada issued a statement praising the federal government’s decision to include businesses of all sizes in its wage subsidy, a component of a package of reforms designed to help businesses keep workers employed as the economy transitions through the COVID-19 pandemic.
“As the employer of 626,000 individuals across Canada, accounting for one in every 30 jobs across the country, the newly announced wage subsidy will play a significant role in providing much-needed support to Canada’s mining industry,” the communiqué reads.
“The support being offered through this new program will enable mining companies to retain their workforces in the face of significant economic hardship brought on by the COVID-19 pandemic” – MAC’s CEO
According to the MAC, as is the case with many sectors, mining has been heavily impacted by COVID-19, with multiple companies reducing or suspending operations at mines, smelters and refineries across the country, which has resulted in hundreds of layoffs of direct and indirect employees.
“The wage subsidy will help prevent further layoffs, thus minimizing both the scale and extent of disruption to both businesses, employees and contractors and better position the mining sector to resume operations and support the many thousands of individuals who depend on it for employment,” the president of the industry group, Pierre Gratton, said in the brief.
The wage subsidy will see 75% of an employee’s salary up to $58,700 temporarily covered by the government to prevent layoffs and the disruption to both businesses and employees associated with such actions.
The benefit will be backdated to March 15, 2020, and businesses and nonprofit organizations seeing a drop of at least 30% in revenue due to COVID-19 will be eligible for the program.

Premier offers Centerra $205m for contentious Ontario project
Premier Gold Mines (TSX: PG) made an offer to Centerra Gold (TSX: CG) to acquire the remaining 50% interest in the Greenstone Gold Mines Partnership for a total consideration of $205 million.
The offer consists of a $175-million cash payment and the assumption of all Centerra’s obligations under the partnership agreement, including the remaining earn-in obligation of approximately $30 million.
It is estimated that the open-pit gold mine could provide nearly 1,000 jobs during construction and pre-production, and 450 workers would be employed full-time during Hardrock’s 15-year mine life span
In a press release, Premier said the acquiring party will be another company that is an assignee of its rights under the offer letter. The proposed assignee has the financial capacity to both acquire Centerra’s 50% interest and advance the Hardrock mine project through construction. It also intends to work with Premier to assist in securing the financial resources required for Premier to fund its 50% share of related mine construction costs.
Hardrock is the Greenstone Gold Mines Partnership’s principal asset and it is located on the Trans-Canada Highway near Geraldton, Ontario.
According to the miners involved in the transaction, Hardrock is one of the most significant large-scale, near permitted, mine development projects in North America.
“This offer should be viewed favourably by Centerra as we believe that it represents a substantial premium to the median of current analyst consensus valuations attributed to Centerra’s 50% interest in GGM, full recovery of their total investment in GGM to date, and aligns with Centerra’s stated focus of maximizing the value of its existing operating assets over new-build opportunities,” Ewan Downie, Premier’s president and CEO, said in the media brief. “The value of the offer is in excess of Premier’s market capitalization, especially when you consider the company’s considerable cash position.”
Hardrock has been a contentious project for both Premier and Centerra, with the latter filing a lawsuit over a project update made in December by Greenstone Gold Mines which Centerra argues should not be considered a “Feasibility Study,” and Premier filing a counterclaim in response.

Harmony Gold curbs output as it shuts nine underground mines
South Africa’s Harmony Gold (JSE: HAR) (NYSE: HMY) has temporarily shutter the nine underground mines it has in the home country to comply with the 21-day lockdown imposed by the government in the wake of the fast-spreading coronavirus.
The company, however, is keeping Kalgold open-pit mine in the North West Province as well as surface treatment plants and retreatment operations in operations.
Harmony is keeping its Kalgold open-pit mine and surface retreatment operations in South Africa open for now.
Harmony’s Hidden Valley gold mine in Papua New Guinea also remains open, but subject to any directive issued in line with the south-western Pacific country’s pandemic response.
As a result of the measures, the Randfontein-based miner expects to only produce between 650kg to 700kg of gold in South Africa during the lockdown.
With governments from Africa to Latin America issuing lockdown orders, disruptions to operations and supply chains are affecting the outlook for industrial and precious metals.
Work is grinding to a halt and operations at mines are being temporarily suspended as companies move to enact measures to protect against the spread of covid-19.
South Africa accounts for 75% of the world’s platinum and 38% of palladium supply, and also produces minerals from gold and manganese to chrome and iron ore.

Excellon, Otis Gold get proxy firm backing for merger
Independent proxy advisory firms Institutional Shareholder Services (ISS) and Glass Lewis & Co. have each recommended that shareholders of Excellon Resources (TSX: EXN) and Otis Gold (TSXV: OOO) approve the proposed merger between the companies.
In February, Excellon announced its intention to acquire fellow Canadian precious metals miner Otis Gold in an all-share deal worth approximately $32.3 million.
ISS and Glass Lewis said that the proposed transaction makes sense for Excellon shareholders as the combined entity would have a more diversified portfolio of assets, consisting of Excellon’s high-grade Platosa silver mine in Mexico and Otis’ Kilgore gold development project in Idaho.
The proxy firms also stated that the combined entity would have more diversification across metals types, geographies, project type and project stage, with $10 million in cash and available funds to deploy.
For Otis shareholders, the arrangement “makes strategic sense” given the significant implied premium and the going concern risk facing the company. Moreover, ISS and Glass Lewis noted that shareholders can still participate in potential upside developments and future growth opportunities of the combined business by receiving Excellon shares.

Pandemic may be final nail in US coal industry’s coffin
The fast-spreading coronavirus pandemic may too heavy of a burden for the already struggling coal miners in the United States, with three companies announcing operations halts due to measures to contain the spread of the disease.
Australia’s Coronado Global Resources (ASX: CRN) announced on Sunday it had idled its US thermal and metallurgical coal mines due to covid-19-induced global economic downturn.
The company, which operates the Buchanan, Logan and Greenbrier mine complexes in Virginia and West Virginia, will keep its Curragh mine in Australia open.
At least three major coal miners have halted operations as covid-19 has rapidly expanded across the US, where the death toll is now expected to reach at least 100,000 people this week.
The operation, which accounts for 65% of Coronado’s output and earnings, will accommodate metallurgical coal export requirements of the miner’s key customers in India and the Asia Pacific, as well as to the Stanwell Power Station, a Queensland government owned entity
Given the significant stockpile of US inventories and continued production from Curragh, operating cash flows are expected to remain positive, Coronado said.
The miner also noted that its US operations will be maintained for immediate restart when market conditions improve and that shipments to Europe, Brazil and the US itself will continue.
Pennsylvania-based Consol Energy (NYSE: CEIX) said on Monday that it was it is temporarily curtailing production at its Bailey coal mine in Pennsylvania for two weeks after two employees tested positive for the coronavirus.
The miner said it’s keeping its Pennsylvania Complex, including the Enlow Fork and Harvey mines, in operations.
The complex has the capacity to produce 28.5 million tonnes of coal a year, while the halted Bailey mine accounts for 11.5 million annual tonnes of the total capacity.
Alliance Resource Partners (NASDAQ: ARLP) said Monday it would temporarily stop producing coal at all its Illinois basin mines as global measures to combat the virus had crushed demand for energy. In addition, the price war initiated by Saudi Arabia and Russia had lowered oil prices even more, it noted.
The miner also said it was withdrawing its initial 2020 operating and financial guidance provided in January, which did not reflect the impact of the covid-19.
“Although we are suspending formal guidance, we currently anticipate ARLP’s total sales tons for 2020 will be approximately 25% below our initial expectations,” president and chief executive, Joseph Craft, said in the statement.
The operations halt is scheduled to last through April 15, though the coal miner said resuming of production could be accelerated or extended, based on business needs of its customers.
“It is important to note that approximately 75% of our domestic sales are targeted to states that depend on coal, more than any other fuel, to generate electricity,” Craft said.
The announcements come as the pandemic has rapidly expanded across the US, where the death toll is now expected to reach at least 100,000 people this week.
Industry decline
Moody’s Investor Services said on Thursday it expected further closures and bankruptcies within the US coal industry as domestic demand for coal was set to drop in the near-term due to the country’s economy shut-down to try reducing the numbers of coronavirus patients.
A slower economic activity is also cutting down US electricity demand, which together with stronger environmental, social and governance concerns could represent “an unprecedented shock” to the coal industry.
“Before the intensification of the coronavirus pandemic in the US, we expected that coal production would fall by15%-20% in the US, to about 550 million st-600 million st,” Moody’s said. “We now expect that the industry conditions will worsen beyond this forecast,” the ratings agency said.
The volume of coal mined in the US has been declining for the past decade, although burning the fuel still accounts for almost one-quarter of all the country’s electricity generation.
Jobs in the sector also continue to shrink. While there are over 129 million people employed by businesses in the US, there are only about 50,000 coal miners, or 0.04% of the country’s total number of people working, employed by the industry.
The latest jobs report, published in early March, shows that there are fewer people employed by the coal sector now (50,600 as of February) than three years ago (50,900 in January 2017). This compares to over 6.4 million jobs being added in the past three years.

De Beers scraps diamond sales event due to coronavirus lockdowns
De Beers, the world’s largest diamond producer by value, has cancelled its third sales event as lockdowns to contain the spread of the novel coronavirus in Botswana, South Africa and India made it impossible for buyers to attend.
The Anglo American unit sells diamonds to a handpicked group of about 80 buyers 10 times a year at events called sights. The third one this year was scheduled to take place from March 30 to April 3.
In February, the diamond giant reported its worst set of earnings since Anglo American (LON:AAL) acquired it in 2012.
De Beers is enabling customers to defer 100% of their sight 3 allocations to later in the year, and said it would continue to seek innovative ways to meet its sightholders supply needs in the coming weeks.
Russia’s Alrosa, the world’s No.1 producer of rough diamonds by carats, said earlier this month that it was studying options for online trade as global travel restrictions make traditional physical inspection of gemstones almost impossible.
The pandemic has placed new worries on the diamond industry, which was finally beginning to show signs of recovery, following a disastrous 2019.

Global demand and prices for all types of diamonds has steadily fallen since last 2018, affecting small stones producers the most, due to an oversupply in that segment that dragged prices down.
The glut of rough and polished stones destroyed margins for the industry’s crucial middlemen who cut, polish and trade them.
Increasing demand for synthetic diamonds also weighed on the market. Man-made stones require less investment than mined ones and can offer more attractive margins.

EMX acquires 18 Chilean royalties from Revelo
Revelo Resources (TSX-V: RVL) finalized the sale to EMX Royalty (TSX-V: EMX) of 18 generative net smelter return royalty interests over exploration properties in Chile for a cash total of $1.16 million.
In a press release, the companies explained that of that amount, $369,907 were applied to fully repay EMX for an outstanding loan due from Revelo.
Revelo said that subsequent to the completion of the transaction, it plans to implement other corporate initiatives to put the company onto a firm basis for future activities.
Among the properties included in the transaction are the 14,000-hectare Arrieros project, which hosts copper, molybdenum and gold; the 10,000-hectare Block 3 project, which hosts molybdenum and gold; the 7,700-hectare Cerro Buenos Aires project, which hosts copper, molybdenum, gold and silver, among others.
Revelo’s total exposure to mineral tenements in northern Chile, either wholly-owned or through royalty interests, is around 200,000 hectares.

BHP commits $8-million to support Chile’s battle against COVID-19
Global miner BHP Group (ASX, LON, NYSE: BHP) launched an $8-million plan focused on helping mitigate the spread of COVID-19 in Chile.
BHP operates the Escondida copper mine, which is the world’s largest, and the Pampa Norte mine, which consists of two operations, Spence and Cerro Colorado. Both complexes are in the northern Atacama Desert but Escondida and Spence are located in the Antofagasta region while Cerro Colorado is in the Tarapacá region.
Just a week ago, the company announced that it decided to exclude contractors from its Chilean operations for 15 days, in an effort to curb the spread of coronavirus.
Efforts will be focused on the southeast area of Santiago’s Metropolitan Region, Antofagasta and Tarapacá
But as the number of confirmed cases continues to grow, now reaching 2139 including seven deaths, BHP decided to join efforts with the Medical Faculty at the Catholic University with the goal of raising the testing capacity of family healthcare centres located in the southeast area of Santiago’s Metropolitan Region, as well as in Antofagasta and Tarapacá.
In a media statement, the miner said the plan involves an early detection program that includes 150.000 rapid tests able to provide results in 24 hours, 10 units for sampling and mobile tents and permanent units; the expansion of laboratory capacity, including the purchasing of new analysis equipment to maximize the speed for processing tests; community surveillance for cases that test positive and their contacts, something that will be done through primary attention centres and telemedicine; and a 24/7 call centre for identifying potential cases.
“In addition, BHP will implement a program to support communities and high-risk, vulnerable groups in the regions where the company operates, Antofagasta and Tarapacá,” the communiqué reads. “This will allow the delivery of supplies, sanitization of public areas, areas for the isolation of potential cases and support to the state network to increase medical rounds, supplies and treatment for high-risk people.”

Corriente Resources’ mining camp in Ecuador set on fire
The Esperanza camp, which is part of the San Carlos Panantza mining complex in Ecuador, was intentionally set on fire and destroyed this weekend, according to information made public by the Ministry of Energy and Natural Non-Renewable Resources.
The copper project, located in the southeastern province of Morona Santiago, is operated by Explorcobres S.A.(EXSA), a subsidiary of Chinese-owned, Canada-based Corriente Resources.
According to the ministry, the arsonists also stole valuable objects from the camp.
San Carlos Panantza has seen its fair share of conflict since the early 2000s, as it is opposed by the Shuar First Nation, in whose ancestral territory the project sits
“We reject these acts of vandalism and the destruction of the property that belongs to the San Carlos Panantza mining project,” the department said in a statement. “We also reject the fact that the decree of state of emergency was violated.”
Two weeks ago, Ecuador declared a state of emergency to deal with the growing number of COVID-19 infections. As of Sunday, the country had registered 1,835 confirmed cases and 48 deaths.
Besides pointing out the fact that the vandals violated the mandatory curfew that goes from 2 p.m. to 5 a.m., the Ministry of Energy also insinuated that police didn’t do their job as they are mandated to guarantee the safety of mining operations.
“We demand that authorities investigate this incident so that those responsible for the fire can be held accountable,” the communiqué reads.
San Carlos Panantza is an advanced-stage project whose reserves have been estimated at 6.6 million tonnes of copper. The 41.760- hectare property is set to host an open-pit operation expected to be active for at least 25 years.

Tiny electronics can still rely on gold
A research paper published in Physical Review Letters reveals that gold can stand up to the strain of the next-generation data processing in electronic devices.
The study was carried out because engineers were starting to worry about the possibility of the tiny gold wires that are used in electronics behaving more like a liquid than a solid as circuits shrink to the nanoscale.
To run this experiment, the researchers figured out how to pressurize gold particles just 4 nanometers in length — the smallest particles ever measured
Thus, a research team at Stanford University, Korea Advanced Institute of Science and Technology and Trinity College conducted an experiment in which they used a device known as a diamond anvil cell, normally employed to compress gold. The idea was to put tiny gold particles under extreme pressure, while simultaneously measuring how much that pressure damaged gold’s atomic structure.
The anvil’s pressure dislodged some atoms from the crystal and created tiny defects in the gold. According to the study’s lead scientist, Wendy Gu, such a reaction was expected because a nanoparticle of gold is built like a skyscraper with atoms forming a crystalline lattice of neat rows and columns.
Since the gold particles were only four nanometers in length, to detect the defects Gu and her team shined X-rays through the diamond onto the gold. Defects in the crystal caused the X-rays to reflect at different angles than they would on uncompressed gold.
By measuring variations in the angles at which the X-rays bounced off the particles before and after pressure was applied, the team was able to tell whether the particles retained the deformations or reverted to their original state when pressure was lifted.
“The defects remain after pressure was removed, which told us that gold behaves like a solid even at such scales,” Gu said in a media statement. “For the foreseeable future, gold’s luster will not fade.”
In summary, the findings mean that chipmakers can know with certainty that they’ll be able to design stable nanodevices using gold for years to come.

Mistango to become one of the largest landowners in Kirkland Lake
Hinterland Metals entered into a mining property acquisition agreement with Mistango River Resources (CSE: MIS) to sell its non-core asset, the Teck property, located in the Kirkland Lake Gold Camp in Ontario, Canada.
According to Hinterland, the 2,105-hectare property has been inactive for several years.
The expanded land package is contiguous to Kirkland Lake Gold’s Macassa mine, one of the worlds highest-grade gold mines, and gives Mistango one of the largest land positions in the Kirkland Lake district
The deal entails that Mistango has to pay C$15,000 as well as issue 1,500,000 common shares to Hinterland in exchange for the transfer of 47 mining claims, 22 mining patents, and two mining licenses of occupation, all situated in the Eby, Teck and Grenfell Townships, together with all exploration data and technical information associated with claims.
The additional claims bring Mistango’s adjacent Eby-Baldwin property to a total of 4,300 hectares, which makes the Toronto-based miner one of the largest landowners in the Kirkland Lake camp.
“This acquisition establishes Mistango as a major landholder in Kirkland Lake, particularly along with the western extension of the Amalgamated and Main breaks which hosts excellent geology but has seen substantially less exploration due to its fragmented ownership,” Mistango’s director, Stephen Stewart, said in a media statement. “This Teck-Kirkland acquisition gives us additional coverage along the intersections of the major breaks in the area including the Amalgamated, Main, Cadillac and Kirana faults. The focus of our exploration going forward will be where these major structures crosscut.”

Gap between No. 1 and 2 copper miners widens as Codelco output drops 5.3%
Chile’s Codelco, the world’s second largest copper miner, has fallen further behind BHP (ASX: BHP) in the top producers of the metal’s rank, after reporting that its output for 2019 had fallen by 5.3% to 1.588 million tonnes.
BHP, the world’s biggest mining company, churned out last year 1.749 million tonnes of copper and expects to produce between 1.705 million and 1.820 million tonnes in 2020.
The Chilean miner, which hands all its revenue over to the state, attributed the drop in production to unusual bad weather in the first half of the year, strikes at its Chuquicamata mine and operational issues.
Profit for the year fell 17% compared to 2018 to $1.34 billion, while direct cash costs increased 1.8%.
Company blamed unusual bad weather in the first half of the year, strikes at its Chuquicamata mine and operational issues for the production drop.
Codelco said the poor financial results were a combination lower gross margins, the downward tendency of copper prices, a reduction in physical sales of the metal and molybdenum and weak results obtained from associated investments,
Colin Hamilton, managing director of commodities research at BMO Capital Markets, had anticipated earlier this week that the copper company would soon have to sell non-core assets.
“Any thoughts of shutting unprofitable operations, however, are off the agenda for now given the need to ensure employment,” he wrote in a note to investors.
Hamilton also noted that Codelco was looking increasingly unlikely to be the world’s largest copper miner from this year forward, as depletion and restrictions prove to be headwinds that are too strong.
The escalating number of Chileans infected with the novel coronavirus forced the company on Wednesday to suspend some key projects, including work being carried out to finish transforming Chuquicamata into an underground mine, and early stage projects at Rajo Inca and Traspaso Andina.
The halted projects are part of a 10-year, $40 billion ongoing plan to upgrade its aging mines and keep up production rates. The scheme, however, could further jeopardized by the effects of the measures taken to deal with the global pandemic crisis.
“Although the country’s government has taken proactive measures to contain the economic and health impacts of the covid-19, the ripple effects of a copper supply shock remain to be seen,” Mariano Pablo Machado, senior Americas analyst at global risk consultancy Verisk Maplecroft, said this week.
Codelco operates seven mines and four smelters, all in Chile. Its assets account for 10% of the world’s known proven and probable reserves and about 11% of the global annual copper output.

Giyani gets approval for Lobatse environmental plan
Giyani Metals (TSXV:EMM) has received final approval from the Department of Environmental Affairs (DEA) in Botswana for its Lobatse manganese project’s environmental management plan (EMP).
The environmental framework required to proceed with exploration activities at Lobatse is now in place, the company says.
The final approval was granted after the customary one-month public review process during which the company was required to advertise the details of the EMP in the Government Gazette and local newspapers. During the period of review, there were no concerns raised by any stakeholders, and as a result, the DEA issued an official acceptance letter last week.
“This is another great example of Botswana’s dedication to supporting its mining industry, especially as the country has introduced its own in-country restrictions following the covid-19 global pandemic,” CEO Robin Birchall stated in a media release.
This approval was the last of the three that the company has received across its K.Hill, Lobatse and Otse project sites.
Shares of Giyani Metals rose more than 9% at Friday’s open. The Oakville, Ontario-based manganese explorer has a market capitalization of C$10.25 million.

Petra Diamonds halts 2020 production target on covid-19
Struggling Petra Diamonds (LON:PDL) has had to halt its production outlook for fiscal 2020 as is closing its mines in South Africa for a mandatory 21-day lockdown aimed at tackling the worsening coronavirus pandemic.
The scaled-back operations will be monitored and managed according to the new procedures put in place to protect the health and safety of all staff, it said.
Petra noted that after the lockdown period is up, it would be possible to ramp operations to steady-state production levels within a relatively short timeframe.
Petra had been already hit by weak diamond market conditions and power issues in South Africa, where it has two of its three mines.
The company, which had been already hit by weak diamond market conditions and power emergencies in the home country, had said in July it expected to produce 3.8 million carats during fiscal 2020.
Petra Diamonds also said it was in “active talks” with a South African lender for near-term financing.
The company has tried to turn around its fortunes after piling up debt to expand its flagship Cullinan mine in South Africa, where the world’s largest-ever diamond was found in 1905. The renowned open-pit mine produces about a quarter of the world’s gem quality diamonds, and the vast majority of blue stones.
The company’s share price collapsed to a record low amid falling diamond prices that forced it to write down the value of its mines in September by almost $250 million.
The financial struggles prompted the miner to launch a restructuring that ended in November with a number of organizational changes.
Petra also owns the Koffiefontein diamond mine in South Africa and Williamson in Tanzania, which remains in full operations.

South Africa’s lockdown to hit Anglo American output
Diversified miner Anglo American (LON: AAL) said on Friday that South Africa’s 21-day lockdown to slow down the spread of the novel coronavirus will impact its iron ore and coal guidance the most.
The company, founded in South Africa more than 100 years ago, said production at its Kumba Iron Ore mine will drop by up to 3 million tonnes this year, while thermal coal output will be reduced by 1.5 to 2 million tonnes.
It noted that the rail and port logistics infrastructure to support the export of both commodities is expected to continue to service the operations during the three-week period.
Production at the company’s Kumba Iron Ore mine will drop by up to 3 million tonnes this year.
Anglo also lowered output of platinum and diamonds, but the National Union of Mineworkers (NUM) told Business Maverik the fact the company is keeping its mines open, though with less employees, was a “reckless and inhuman” pursuit of profit.
Venetia diamond mine, run by the group’s subsidiary De Beers, will operate with staff levels cut to 25%. Mogalakwena, the world’s largest palladium mine outside Russia, and Mototolo platinum mine continue to operate with a reduced workforce and production, subject to further planning, Anglo said.
Three platinum operations — Amandelbult, Modikwa and Kroondal —as well as the Mortimer and Waterfall smelters, are being placed onto care and maintenance, it said.
Anglo American said most of its major operations in other countries had so far not been materially impacted. However, it has extended a slowdown in construction at its Quellaveco copper mine in Peru and paused work in its recently acquired Woodsmith polyhalite project in Britain.
With governments from Africa to Latin America issuing lockdown orders, disruptions to operations and supply chains are affecting the outlook for industrial and precious metals.
Work is grinding to a halt and operations at mines are being temporarily suspended as companies move to enact measures to protect against the spread of covid-19.

Australian gas companies to explore renewable hydrogen market
The Australian Gas Infrastructure Group AGIG, Jemena Gas Networks, AusNet and Evoenergy have collaboratively released an expression of interest to have companies and organizations in the international hydrogen supply chain approach them with proposals on how to deliver Australia’s low carbon vision through hydrogen.
According to the firms involved in this initiative, the first step for them is to seek information on the cost of deploying renewable hydrogen at scale.
Together, AGIG, Jemena Gas Networks, AusNet and Evoenergy represent the largest gas networks, customer base and gas consumption levels in Australia, supplying to more than 10 million people
“Through this expression of interest process, suppliers of key inputs to the international hydrogen supply chain are invited to comment on the feasibility, approach and cost of achieving 10% renewable hydrogen by volume across gas networks in the eastern and southern states of Australia,” AGIG’s CEO, Ben Wilson, said in a media statement. “We believe this objective is achievable by 2030.”
According to Wilson, with their customers’ needs in mind, AGIG, Jemena, AusNet and Evoenergy believe the gas sector shares a common vision for a low carbon future enabled by renewable hydrogen.
The executive said that a document released in 2017, titled ‘Gas Vision 2050,’ sets the trajectory for decarbonising Australia’s gas supply into the future through hydrogen and other renewable sources.
Wilson acknowledged that, beyond the four firms’ individual commitments, Australia has a National Hydrogen Strategy that has prompted significant work towards lowering carbon initiatives using hydrogen. The Strategy also proposes hydrogen blending across towns and cities at volumes of up to 10% into gas networks.

Barrick unveils 10-year plan to become world’s most valued gold miner
Barrick Gold (TSX: ABX) (NYSE: GOLD), the world’s second largest gold miner, has unveiled a 10-year production plan aimed at becoming the most valued bullion company.
The strategy, outlined in its first annual report since its merger with Randgold Resources, includes boosting Barrick’s production to about 5 million ounces of gold a year, with the bulk coming from its North American operations.
President and chief executive officer, Mark Bristow, said Nevada Gold Mines — its recent joint venture with Newmont (NYSE: NEM) — would be the “value foundation” of its business moving forward.
“Already the world’s largest gold mining complex, it holds enormous potential for growth,” he said.
Bristow warned the new guidance might be impacted if operations were disrupted due to efforts to slow the spread of the covid-19. He called the pandemic “a global disaster which is changing the way we work and live in a radically disruptive process with currently no clear end in sight”.
In the past year, Barrick has been focusing on its tier one assets and has reported strong performance across the group, particularly at Cortez mine in Nevada and Veladero in Argentina.
It has also boosted production at Kibali, Congo’s biggest gold mine, which last year beat its production guidance of 750,000 ounces of gold by a substantial margin, delivering a new record of 814,027 ounces.
Porgera in Papua New Guinea has tier one potential but faces many challenges in the form of legacy issues and an unruly neighbourhood,” Bristow said, adding the mine had exceeded guidance and the company continued to negotiate a 20-year lease extension with the government.
The executive, who took the helm in January 2019, said the work done over the past year had equipped Barrick to move to the next level.
“All in all, I am confident that we are more than capable of delivering on our promise: to build the world’s most valued gold company,” he said. Bristow noted that Barrick’s definition of value was more wide-ranging and included factors such as economic benefits, the care with which it treated its people, communities and environments, its strategic focus on long-term sustainability and returns for investors.

Tudor has enough cash for 2020 drilling campaign at Treaty Creek project
Tudor Gold (TSXV: TUD) announced that it is fully funded to execute a significantly larger drilling and exploration program compared to the campaign that was carried out in 2019 at its Treaty Creek project in British Columbia, western Canada.
Tudor has reported that the southern half of the system contains 188m oz gold, 1.2 bn oz silver, 55bn lbs. copper in resources all categories included. In proven and probable reserves, the numbers are 47m oz gold, 214m oz silver, and 10bn lbs copper
Back in December, Tudor raised enough capital which, combined with warrants recently exercised, provided enough cash to execute a fully funded and ambitious drill campaign.
“The Goldstorm system is currently open at depth and along the northeast axis of the mineralized body. The drill program is designed to extend and to explore the limits of the Goldstorm system to the southeast as well as to the northeast and to depth,” Tudor’s VP of project development, Ken Konkin, said in a media statement. “We anticipate drilling approximately 18,000 to 20,000 metres of HQ and NQ diameter core from 7-10 drill platforms with four diamond drill rigs. Compared to the drill program last year (14 diamond drill holes over 9,781.8 meters), the planned 2020 drill program will be much larger.”
According to Konkin, the current known length of the northeast axis of the Goldstorm System is over 850 metres long and the southeast axis is at least 600 metres across, while the system remains open in all directions and to depth.
The executive also said that the best mineralization encountered to date is from the two consecutive 150-metre step-out holes to the northeast: GS-19-42 yielded 0.849 g/t Au Eq over 780 metres with 1.275 g/t Au Eq over 370.5m and GS-19-47 yielded 0.697 g/t Au Eq over 1,081.5 metres with 0.867 g/t Au Eq over 301.5 metres.
Treaty Creek is located 70 kilometres north of the town of Stewart and only 10 kilometres from the former Eskay Creek mine. The property is 60% owned and operated by Tudor Gold, while American Creek and Teuton Resources each have a 20% share.

Sumitomo halts mines in Bolivia, Madagascar
Japan’s Sumitomo Corp. became on Thursday the latest major diversified miner to temporarily suspend operations at some of its mines to prevent the spread of the novel coronavirus.
The measure affects the company’s San Cristobal silver-zinc-lead mine in Bolivia and Ambatovy nickel mine in Madagascar, as all-day or night curfews have been imposed in those countries.
It excludes any facilities that require continuous operation, such as power plants.
Bolivia declared on Wednesday a national health emergency and extended its borders lockdown to April 15 from March 31. It has also tightened restrictions on movement, permitting only one person per household to go out between the hours of 7 am and noon on weekdays.
At least two cities in Madagascar have been in strict lockdown since March 20 and any transport, except for goods, is forbidden.
There are now more than 2,400 confirmed cases of covid-19 across Africa and growing warnings that the pandemic will cause major challenges for the continent’s under-resourced health services.

GoGold hits high grades at Los Ricos South
GoGold Resources’ (TSX: GGD) most recent exploration results include near-surface, high-grade silver and gold intersections around historical underground workings from the Los Ricos South project in Mexico.
The Main area returned 18.8 metres of 255 g/t silver-equivalent starting at 3 metres, 19.5 metres of 199 g/t silver-equivalent starting at 4.5 metres and 26.4 metres of 203 g/t silver-equivalent starting at surface.
“Drilling continues at Los Ricos with 6 drill rigs as we accelerate the drilling required for our initial resource,” Brad Langille, the company’s president and CEO, said in a release.
“At the Los Ricos North project, we continue with the groundwork preparing for an upcoming drill campaign, which we anticipate commencing after the Easter break.”
The eight holes reported are from the Main and San Juan areas, with extensive underground workings nearby. The company believes that gold and silver has been mined at Los Ricos since the 16th century.
GoGold has subdivided the 225-sq.-km project in Jalisco state into southern and northern portions. Drilling at Los Ricos South is currently focused around historical mines. Last year, the company drilled 17,400 metres at the project.
The company also announced that its operations were not affected by the spread of the covid-19 virus
On Mar. 18, the company also announced that its operations were not affected by the spread of the covid-19 virus and that it has implemented additional sanitization, monitoring and education efforts.
In March of 2019, the company entered into an option agreement to acquire Los Ricos and accelerated the acquisition in August by agreeing to pay a total of US$7.1 million in cash and shares over a 24-month period.
In February, GoGold closed a $25-million bought deal financing.
In addition, the company operates the Parral tailings project in Mexico’s Chihuahua state, which features two tailings sites with one currently producing silver.

Las Conchitas returns more gold for Mako
Mako Mining has released the results of six holes drilled to test the Bayacun zone at the Las Conchitas area within the San Albino project in Nicaragua, which intercepted high-grade gold and silver mineralization at shallow depths.
Highlights include 1.6 metres of 84.64 g/t gold and 80.2 g/t silver at 80 metres from surface as well as 3.9 metres of 25.78 g/t gold and 18.3 g/t silver at 45 metres from surface.
It appears that the drilling at the 2.5-sq.-km Las Conchitas area, which has been ongoing since 2019, has traced at least eight mineralized zones that are shallow dipping and high grade.
The latest results extended the Bayacun zone to 140 metres down-dip; it remains open both on strike and down dip
The latest results extended the Bayacun zone to 140 metres down-dip; it remains open both on strike and down dip.
“Every hole referenced in this press release hit significant gold mineralization,” Akiba Leisman, the company’s CEO, said in a release.
“The Bayacun zone of the Las Conchitas area is proving to be a predictable and high-grade target at relatively shallow depths.”
Leisman added that one drill rig is expected to continue exploration work at Las Conchitas, aimed at outlining a maiden resource for this area next year. Assays for an additional 19 holes, drilled to target Bayacun, are pending.
The Las Conchitas area is approximately 2.5 km south of the 500 t/d San Albino open pit project, which is under construction with a first gold pour expected in the fourth quarter.
Earlier this month, the company announced that it has reduced the number of people at the operation to reduce potential COVID-19 infection risks.
Although mining of gold mineralization was suspended as a result, Mako shifted its efforts towards earthworks and construction of the tailings facility.
The San Albino project covers a total of 150 sq. km and includes a 23-km strike of the Corona de Oro gold belt.
