Cobalt: A precarious supply chain

Cobalt: A precarious supply chain

 

How does your mobile phone last for 12 hours on just one charge? It’s the power of cobalt, along with several other energy metals, that keeps your lithium-ion battery running.

The only problem? Getting the metal from the source to your electronics is not an easy feat, and this makes for an extremely precarious supply chain for manufacturers.

This infographic comes to us from LiCo Energy Metals TSXV:LIC and it focuses on where this important ingredient of green technology originates from, and the supply risks associated with its main sources.

What is cobalt?

Cobalt is a transition metal found between iron and nickel on the periodic table. It has a high melting point (1493° C) and retains its strength to a high temperature.

Similar to iron or nickel, cobalt is ferromagnetic. It can retain its magnetic properties to 1100° C, a higher temperature than any other material. Ferromagnetism is the strongest type of magnetism: it’s the only one that typically creates forces strong enough to be felt and is responsible for the magnets encountered in everyday life.

These unique properties make the metal perfect for two specialized high-tech purposes: superalloys and battery cathodes.

Superalloys

High-performance alloys drive 18% of cobalt demand. The metal’s ability to withstand intense temperatures and conditions makes it perfect for use in:

  • Turbine blades

  • Jet engines

  • Gas turbines

  • Prosthetics

  • Permanent magnets

Lithium-ion batteries

Batteries drive 49% of demand—and most of this comes from cobalt’s use in lithium-ion battery cathodes:

Type of lithium-ion cathode Cobalt in cathode Spec. energy (Wh/kg)
LFP 0% 120
LMO 0% 140
NMC 15% 200
LCO 55% 200
NCA 10% 245

The three most powerful cathode formulations for li-ion batteries all need cobalt. As a result, the metal is indispensable in many of today’s battery-powered devices:

  • Mobile phones (LCO)

  • Tesla Model S (NCA)

  • Tesla Powerwall (NMC)

  • Chevy Volt (NMC/LMO)

The Tesla Powerwall 2 uses approximately seven kilograms and a Tesla Model S (90 kWh) uses approximately 22.5 kilos of the energy metal.

The cobalt supply chain

Cobalt production has gone almost straight up to meet demand, more than doubling since the early 2000s.

But while the metal is desired, getting it is the hard part.

1. No native cobalt has ever been found.

There are four widely distributed ores that exist but almost no cobalt is mined from them as a primary source.

2. Most cobalt production is mined as a byproduct.

Mine source % cobalt production
Nickel (byproduct) 60%
Copper (byproduct) 38%
Cobalt (primary) 2%

This means it is hard to expand production when more is needed.

3. Most production occurs in the Democratic Republic of Congo, a country with elevated supply risks.

Country Tonnes %
Total 122,701 100.0%
United States 524 0.4%
China 1,417 1.2%
DRC 67,975 55.4%
Rest of World 52,785 43.0%

(Source: CRU, estimated production for 2017, tonnes)

The future of cobalt supply

Companies like Tesla and Panasonic need reliable sources of the metal and right now there aren’t many failsafes.

The United States hasn’t mined cobalt in significant volumes since 1971 and the USGS reports that the U.S. only has 301 tonnes of the metal stored in stockpiles.

The reality is that the DRC produces about half of all cobalt and it also holds approximately 47% of all global reserves.

Why is this a concern for end-users?

1. The DRC is one of the poorest, most corrupt and most coercive countries on the planet.

It ranks:

  • 151st out of 159 countries in the Human Freedom Index

  • 176th out of 188 countries on the Human Development Index

  • 178th out of 184 countries in terms of GDP per capita ($455)

  • 148th out of 169 countries in the Corruption Perceptions Index

2. The DRC has had more deaths from war since WWII than any other country on the planet.
Recent wars in the DRC:

  • First Congo War (1996-1997)—An invasion by Rwanda that overthrew the Mobutu regime.

  • Second Congo War (1998-2003)—The bloodiest conflict in world history since WWII, with 5.4 million deaths.

3. Human rights in mining

The DRC government estimates that 20% of all cobalt production in the country comes from artisanal miners—independent workers who dig holes and mine ore without sophisticated mines or machinery.

There are at least 100,000 artisanal cobalt miners in the DRC and UNICEF estimates that up to 40,000 children could be in the trade. Children can be as young as seven years old and they can work up to 12 hours with physically demanding work earning $2 per day.

Meanwhile, Amnesty International alleges that Apple, Samsung and Sony fail to do basic checks in making sure the metal in their supply chains did not come from child labour.

Most major companies have vowed that any such practices will not be tolerated in their supply chains.

Other sources

Where will tomorrow’s supply come from and will the role of the DRC eventually diminish? Will Tesla achieve its goal of a North American supply chain for its key metal inputs?

Mining exploration companies are already looking at regions like Ontario, Idaho, British Columbia and the Northwest Territories to find tomorrow’s deposits.

Ontario: Ontario is one of the only places in the world where cobalt-primary mines have existed. This camp is near the aptly named town of Cobalt, which is located halfway between Sudbury, the world’s nickel capital, and Val-d’Or, one of the most famous gold camps in the world.

Idaho: Idaho is known as the Gem State while also being known for its silver camps in Coeur d’Alene—but it has also been a cobalt producer in the past.

B.C.: The mountains of B.C. are known for their rich gold, silver, copper, zinc and met coal deposits. But cobalt often occurs with copper and some mines in B.C. have produced cobalt in the past.

Northwest Territories: Cobalt can also be found up north, as the NWT becomes a more interesting mineral destination for companies. One hundred and sixty kilometres from Yellowknife, a gold-cobalt-bismuth-copper deposit is being developed.

Diamonds—2016 glitter in review

December 22nd, 2016

by Greg Klein | December 22, 2016

The stones began the year still mired in their 2015 slump, in which rough prices reportedly fell 15%. The two biggest players, representing nearly two-thirds of global production, didn’t exactly agree on strategy. De Beers cut production and lowered prices while Alrosa initially boosted production, held prices stable and stockpiled some output. By April De Beers raised prices and Alrosa lowered production. The following month had De Beers talking about a “fragile recovery.”

Diamonds—2016 glitter in review

Sales records for polished got pulverized, though. In May Sotheby’s raked in $32 million for the 15.38-carat Unique Pink in a jewelry sale that totalled a world record $175.1 million. The next day Christie’s scooped up $58.25 million for the 14.62-carat Oppenheimer Blue, “a new record price for any gemstone and per carat.”

Rough rode roughshod over records, too. The week before Sotheby’s and Christie’s big sales, Lucara Diamond TSX:LUC got $63.11 million for its fresh-from-the-mine 812.77-carat Constellation. High expectations led to disappointment in late June, however, when the company rejected a $61-million offer for its 1,109-carat Lesedi La Rona rough stone, the second-biggest diamond ever found. Lucara wanted at least $70 million.

As for Canadian diamond mining, it thrived.

A 100-million-carat production milestone brought celebrations to Diavik, the Northwest Territories JV of Rio Tinto NYSE:RIO and Dominion Diamond TSX:DDC. In July Dominion finally decided to add the Jay pipe and its 78.6 million carats to the company’s majority-held Ekati mine.

The year brought new mines to Canada too. Gahcho Kué, the world’s largest new diamond producer in 13 years, was officially opened in September by partners De Beers and Mountain Province Diamonds TSX:MPV. October saw Stornoway Diamond TSX:SWY do the same at Renard, Quebec’s first diamond mine. It reached commercial production just days before Christmas.

Looking at potential mines-to-be, Peregrine Diamonds TSX:PGD took its Chidliak project on Baffin Island to PEA in July. In Saskatchewan’s Fort à la Corne region, meanwhile, Shore Gold TSX:SGF continued working on a feasibility update for its majority-held Star-Orion South project. Back in the NWT, Kennady Diamonds TSXV:KDI completed its maiden resource in December.

The company’s Kennady North project sits in the same Lac de Gras region hosting Ekati, Diavik and Gahcho Kué. November marked the 25th anniversary of the Chuck Fipke/Stewart Blusson Ekati discovery that triggered the world’s biggest staking rush, brought diamond mining to Canada and helped transform the diamond industry.

In December the vertically integrated company Almod Diamonds announced plans to broaden the NWT diamond industry, the backbone of the territorial economy, by re-opening a Yellowknife cutting and polishing facility.

A few days after that announcement, the allure of diamonds played out differently in an Atlanta department store. Eighty-six-year-old Doris Payne, a determined, unrepentant and often unsuccessful diamond thief, wracked up another arrest. She’s been stealing stones for over sixty years.

With maiden resource complete, Kennady Diamonds sees PEA late next year

December 14th, 2016

It’s “quite possibly a record timeframe in the history of Canadian diamond exploration,” according to Kennady Diamonds TSXV:KDI president/CEO Rory Moore. One of several small dykes discovered by the De Beers/Mountain Province Diamonds TSX:MPV JV in 2000, the Kelvin kimberlite wasn’t drilled until 2012. By that time Mountain Province, preoccupied with the adjacent Gahcho Kué, had created Kennady to investigate the neighbouring turf. On December 12 the spinout released Kelvin’s resource, the first such estimate for the 71,000-hectare Kennady North property.

With maiden resource complete, Kennady Diamonds sees PEA late next year

Kennady has a busy year ahead, with plans for resource
estimates on two additional kimberlites prior to PEA.

Using a one-millimetre bottom cutoff, the all-indicated resource shows 8.5 million tonnes averaging 1.6 carats per tonne for 13.62 million carats of diamonds. Average value comes to $63 per carat.

The deposit extends to a depth of 510 metres, with about 85% within a potential open pit to 330 metres’ depth and the rest a possible underground mine.

It’s been a productive four years and five months since Kennady first put rigs to work. The resource considered 175 holes totalling 40,041 metres, microdiamond samples totalling 20.23 tonnes. a mini-bulk sample of 44.8 tonnes and two more bulk samples totalling 1,067 tonnes. The bulk samples gave up 2,262 carats for valuation.

Announced last month, Antwerp’s verdict—actually two separate valuations that arrived at the same amount—came to an average $52 per carat. But Kennady emphasized the lopsided values of bigger diamonds, including a 2.84-carat stone valued at $2,640 per carat.

Moore pointed to a “similar trend” at Gahcho Kué, five kilometres away. “The five highest-value Kelvin diamonds represent 1% of the sample weight but 20% of the total value. This trend is a key determinant of overall value.”

A PEA’s now scheduled for late 2017 and would incorporate resource estimates to come from the Faraday 2 and 3 kimberlites, which will undergo bulk sampling this winter. Kennady also plans geophysics over 4,233 hectares acquired in August just south of Gahcho Kué. The company will consider exploration drilling following the bulk samples.

Earlier this month Kennady, along with Athabasca Basin uranium standout NexGen Energy TSX:NXE, shared the 2016 Exploration Company of the Year award at Mines and Money London.

92 Resources reports NWT lithium of 1.58% Li2O over 8.78 metres with 31 ppm Ta2O5

November 28th, 2016

by Greg Klein | November 28, 2016

92 Resources reports NWT lithium

Six known pegmatites with impressive strike lengths
offer considerable potential, the company states.

A second and final batch of lithium assays from Hidden Lake’s summer program once again “exceeded our expectations,” 92 Resources TSXV:NTY stated November 28. The company now reports that 101 out of 223 channel samples from three pegmatites on the Northwest Territories project graded over 1% Li2O, with 59 surpassing 1.5%. Tantalum was found too, with some highlights from this batch showing:

HL3 pegmatite

  • 1.58% Li2O and 31 ppm Ta2O5 over 8.78 metres
  • (including 1.78% Li2O and 31 ppm Ta2O5 over 6.93 metres)

HL1

  • 1.26% Li2O and 27 ppm Ta2O5 over 8.72 metres

HL4

  • 1.71% Li2O and 33 ppm Ta2O5 over 5.78 metres

Of 10 grab samples taken during regional prospecting, one graded 1.86% Li2O. As reported earlier this month, two more pegmatites have been found on the property, bringing the total to six so far. “With exposed strike lengths of 350 to 800 metres, the potential for significant concentrations of spodumene pegmatites remains very high,” said president/CEO Adrian Lamoureux.

Located along Highway 4, 40 kilometres east of Yellowknife, the 1,567-hectare property lies within the Yellowknife lithium pegmatite belt.

In September the company closed its acquisition of the Pontax lithium property in northern Quebec, where historic satellite imagery and government mapping have shown pegmatite outcrops.

Peregrine Diamonds outlines Nunavut spending plans as Chidliak moves to pre-feas

November 25th, 2016

by Greg Klein | November 25, 2016

Having poured about $23 million into Nunavut so far, Peregrine Diamonds TSX:PGD plans to spend another $15.5 million to $17 million next year on its Chidliak project, the Nunatsiaq News reported November 25. Most of the $23 million went to Iqaluit, home to an estimated 7,590 people. “It will cost between $50 and $75 million to go from here to where we need to get to,” the journal quoted president/CEO Tom Peregoodoff.

Peregrine Diamonds outlines Nunavut spending plans as Chidliak moves to pre-feas

Chidliak would have a 10-year lifespan,
according to last summer’s PEA.

The Baffin Island project reached PEA in July, calling for a capex of $434.9 million, an amount relatively modest for an isolated operation but considerable for a territory of about 37,082 people. The company hopes to reach feasibility by H2 2019, complete permitting by the end of that year and begin construction in H2 2019. Should hopes, financing and feasibility fall into place, Peregrine might be digging diamonds by 2021.

Brothers Robert and Eric Friedland own about 25% and 21% of the company respectively.

New infrastructure would include an all-season road to Iqaluit, about 120 kilometres southwest. The government of Nunavut hopes to have an $85-million deep sea port built there by 2020.

The territory currently has two other mines in production, Agnico Eagle’s (TSX:AEM) Meadowbank gold mine about 300 kilometres west of Hudson Bay and Baffinland Iron Mines’ Mary River iron ore operation roughly 800 kilometres north of Chidliak. Baffinland trucks ore to its own port, 100 kilometres north of the mine.

Peregoodoff said the company has yet to negotiate an Inuit Impact and Benefits Agreement, but stated such a deal would probably resemble agreements signed with Northwest Territories diamond producers, the News added.

In October the paper reported Nunavut’s 14,000-member Qikiqtani Inuit Association received more than $24 million over two years from Mary River.

Should Peregrine meet its goal, Chidliak wouldn’t be Nunavut’s first diamond operation. Just across the border from the NWT’s Lac de Gras camp, Nunavut’s Jericho mine produced gems between 2006 and 2008. Shear Minerals gave up on its restart attempt in 2012, leaving taxpayers with a large part of an estimated $10.5-million clean-up bill.

Yet diamond mining transformed the NWT economy. According to figures supplied by the NWT and Nunavut Chamber of Mines, between 1996 and 2015 the industry provided over 50,000 person-years of employment, 49% northern and 24% aboriginal. By far the territory’s largest private sector industry, diamond mining created 29% of the NWT’s GDP in 2014. Direct and indirect benefits bring the number up to 40%, according to chamber data.

Arctic Star/Margaret Lake Diamonds form JV, follow Kennady’s approach to NWT kimberlites

November 15th, 2016

by Greg Klein | November 15, 2016

A new joint venture brings together Arctic Star Exploration TSXV:ADD and Margaret Lake Diamonds TSXV:DIA in the Northwest Territories’ Lac de Gras region. Finding inspiration in Kennady Diamonds’ (TSXV:KDI) success at Kennady North, the partners plan a similar approach to their newly compiled property.

By posting an approximately $200,000 bond with the NWT government, Margaret Lake has earned a 60% interest in 23 claims totalling 18,699 hectares comprising the Diagras property, the JV announced November 15. Hosting 13 known diamondiferous kimberlites, the claims were formerly part of Arctic Star’s 54,000-hectare T-Rex property.

Arctic Star/Margaret Lake Diamonds form JV, follow Kennady’s approach to NWT kimberlites

The bond accompanies an application to extend the Diagras claims to August 2017.

“We identified the claims we wanted to joint venture based on our evaluation of historic data and we specifically focused on those claims that have known kimberlitic occurrences,” said Margaret Lake president/CEO Paul Brockington. His company will act as project operator.

The JV intends to follow Kennady’s modus operandi. The property’s Kelvin and Faraday kimberlites were dropped by De Beers and Mountain Province Diamonds TSX:MPV as they advanced Gahcho Kué, recently opened as the world’s largest new diamond mine in 13 years.

De Beers considered Kelvin and Faraday low grade, based on their lack of prominent magnetic anomalies, according to the Arctic/Margaret JV. Mountain Province then spun out Kennady to explore the pipes. That company “applied ground geophysics, gravity and Ohm mapper EM, which revealed extensions to these kimberlites that were not revealed in the magnetics,” the Diagras partners stated. “Subsequent drilling and bulk sampling has shown that these non-magnetic phases of the kimberlites have superior diamond grades to the magnetic phases and significantly increase the tonnage potential.”

Looking at some nearby deposits, the JV states that certain kimberlites at the Rio Tinto NYSE:RIO/Dominion Diamond TSX:DDC Diavik mine and the high-grade portions of Peregrine Diamonds’ (TSX:PGD) majority-held DO-27 kimberlite “are non-magnetic, proof that a magnetic-only approach in the Lac de Gras field could miss significant diamondiferous kimberlite bodies.”

The JV plans to follow Kennady’s surveying approach at Diagras. Most of the property’s kimberlites have had only one to three drill holes into their magnetic anomalies.

The partners also see potential in “two untested geophysical targets and several diamond indicator mineral anomalies that are not clearly sourced from the known pipes.” Ground geophysics are scheduled to begin next spring.

A transformational discovery

November 10th, 2016

Lac de Gras glitter became the backbone of the NWT economy

by Greg Klein

This is the second of a two-part feature. See Part 1.

The greatest staking rush the world’s likely seen, a shakeup of the global diamond industry and a tremendous boost to Northwest Territories finances—all that started with the Ekati discovery announced by Chuck Fipke 25 years ago this week. The effects on the NWT alone were momentous. The exploration sector boomed like never before, reaping four discoveries in six years that became working mines, while communities and individuals realized benefits both tangible and intangible.

Exploration fervour “certainly caused an injection into the economy,” notes Tom Hoefer, NWT and Nunavut Chamber of Mines executive director. “But where it really made a difference was when we had mines developed.”

Lac de Gras glitter became the backbone of the NWT economy

The Ekati mine began a transformation that
out-performed all other resources and sectors in the NWT.

It actually took two operations, Ekati and Diavik, to offset the territory’s 1990s economic malaise, he says. Yellowknife’s Giant and Con mines were winding down their 50 to 60 years of gold production. Around the same time, Nunavut’s 1999 separation dealt a blow to NWT revenue. “So there was a double hit on the economy. When Ekati went into production, it wasn’t enough to offset that economic downturn. It wasn’t until Diavik that the economy turned around significantly.

“It was almost palpable when Diavik got its approval. You could cut it, you could just feel it, all of a sudden people were saying, ‘Now we’re set.’ Those turned out to be world-class diamond mines, so in hindsight people were right.”

Of more than $60 billion worth of NWT mining output since 1932, gold provided 18%. It’s sometimes forgotten that the territory was a major base metals producer too, with zinc accounting for 30% of that $60-plus billion. But less than two decades of diamond production contributed 38%. The value of annual diamond production has topped $2 billion in the past “and I think we’re around $1.7 billion now,” Hoefer says. “That’s pretty significant when you consider that the NWT government’s entire budget is about the same.”

With last year’s shutdown of the Cantung tungsten operation, the territory has no mining but diamond mining. The three mines now in operation rank Lac de Gras as the world’s third-largest producer by value.

Figures from 2014 credit diamond mining with a 29% direct contribution to territorial GDP, by far the largest private sector portion. Chamber data attributes direct and indirect benefits to about 40% .

Taking another perspective, Hoefer points to a 2014 Canada-wide survey on aboriginal perceptions of the mining industry. Outside the NWT and Nunavut, favourable ratings ranged from 25% in Quebec to 45% in the Yukon. NWT responses were 55% favourable compared to 33% unfavourable, with 12% undecided. The territory ranked second only to Nunavut, which had 59/32/9 ratings.

“I would say the reason is all the aboriginal participation we’ve had in mining,” Hoefer says.

An NWT-specific survey taken this year shows overwhelming support. About 80% of respondents expressed positive feelings about the territory’s mining and exploration companies, 83% said regulation works well and 82% want more mining projects.

Those responses might partly result from the way benefits are distributed. Territorial legislation requires mining proposals to address not only environmental impacts but also positive socio-economic effects, Hoefer explains. Companies sign agreements with the government that address training, employment and local spending. The miners then file annual reports stating what they’ve accomplished.

“Put the clock back to before diamonds were discovered and the first mine built, there was maybe just a handful of aboriginal companies that could work with mining.” Now the Chamber lists over 60 NWT aboriginal companies created since Ekati began construction in 1996. They’ve shared over $5 billion of the $12 billion that diamond miners have spent in the territory.

The mines have also contributed over $100 million to communities under Impact Benefit Agreements.

And of course there are the jobs. Lac de Gras diamonds have provided over 24,000 person-years of mine employment.

That’s really in essence what I think a government would want to do with its resources—generate wealth for people who don’t have it.—Tom Hoefer,
executive director of the NWT
and Nunavut Chamber of Mines

“That’s really in essence what I think a government would want to do with its resources—generate wealth for people who don’t have it.”

Looking to the future, Lac de Gras explorers continue the quest for more deposits. Among existing miners, the Rio Tinto NYSE:RIO/Dominion Diamond TSX:DDC 60/40 JV expects Diavik to last until 2024. Plans to add a fourth deposit won’t extend the lifespan but will keep production robust until shutdown, Hoefer says.

De Beers’ technically challenged Snap Lake shut down last year, at a cost of about 750 jobs. Some of them were saved by Gahcho Kué, which last summer became the world’s largest diamond mine to open in 13 years. But despite output that’s expected to be about two and a half times greater than Snap, the open pit will employ fewer people, currently 441. The De Beers/Mountain Province Diamonds TSX:MPV 51%/49% JV sees an initial 12-year mine life, but Mountain Province talks optimistically of extensions.

Getting back to the genesis of all this economic activity, Dominion’s majority-held Ekati would have its life expectancy extended to at least 2030 should the Jay pipe addition pass feasibility and final permitting. The mine employs around 1,500 workers and accounts for about $400 million in annual spending.

Commemorating the quarter-century since Ekati’s discovery, the NWT and Nunavut Chamber of Mines presents a Diamond Gala on November 17, the final evening of this year’s Geoscience Forum. Hoefer says the event will be a three-part celebration recognizing the discovery, the subsequent construction and operation of four mines, and the support of aboriginal governments. Fipke will be on hand as guest speaker, perhaps marvelling at the transformation brought about by his pursuit of Lac de Gras glitter.

92 Resources reports NWT lithium and tantalum channel samples, plans winter drilling

November 8th, 2016

by Greg Klein | November 8, 2016

The first batch of assays from initial channel sampling on the Hidden Lake lithium project “exceeded our expectations,” 92 Resources TSXV:NTY reported November 8. The summer program focused on the LU D12 pegmatite, as well as three newly discovered pegmatites on the property 40 kilometres east of Yellowknife.

92 Resources reports NWT lithium and tantalum channel samples, plans winter drilling

Of 85 samples from 15 channels, 52 graded more than 1% Li2O, including 34 that surpassed 1.5%. The best result showed 1.53% Li2O and 64 ppm Ta2O5 over 11.58 metres, including 1.9% Li2O and 52 ppm Ta2O5 over 9.02 metres.

Tantalum averaged 88 ppm, peaking at 596 ppm. Tantalum grades will be verified through an additional analytical technique, the company added.

Sampling targeted LU D12 over an intermittent strike of about 275 metres. Still to come are assays for another 223 samples, which include the HL1, HL3 and HL4 pegmatites, “where spodumene has been visually identified,” the company stated. 92 Resources also reported finding at least two new pegmatites south of LU D12.

The company has permitting underway for a winter 2017 drill program. The 1,567-hectare Hidden Lake sits within the Yellowknife lithium pegmatite belt along Highway 4.

Although Hidden Lake remains the company’s flagship, in September 92 Resources closed the acquisition of Quebec’s Pontax lithium property, where historic satellite imagery and government mapping have shown pegmatite outcrops.
