Got the minerals?

March 4th, 2019

A new book says self-imposed obstacles block U.S. self-sufficiency

by Greg Klein

“The Middle East has oil, China has rare earths.”

Deng Xiaoping’s 1992 implied threat became all too real eight years later in the Senkaku aftermath, when RE dependency put Japan and the West at China’s mercy. But just as the United States overcame the 1973 OPEC embargo to become the world’s leading oil producer, that country can overcome its growing reliance on dodgy sources of mineral production and processing. So say authors Ned Mamula and Ann Bridges in Groundbreaking! America’s New Quest for Mineral Independence.

Their country’s problem isn’t geology but policies, the book argues. Repeatedly pointing to Canada and Australia as role models, the authors say their own country’s mining potential can restore mining self-sufficiency, or at least minimize a crippling dependency.

A new book says self-imposed obstacles block U.S. self-sufficiency

Indeed, the mighty nation has a mighty problem with minerals: Imports supply many critical minerals and metals in their entirety, with heavy reliance on Russia and especially China, “countries we consider at best our competitors, and at worst our adversaries.”

Rare earths stand out as the “poster child for U.S. critical mineral vulnerability.” As the authors note, REs remain “essential for military and civilian use, for the production of high-performance permanent magnets, GPS guidance systems, satellite imaging and night vision equipment, cellphones, iPads, flat screens, MRIs and electric toothbrushes, sunglasses, and a myriad of other technology products. Since they offer that extra boost to so many new technologies, these rare earth metals rival energy in importance to our 21st century lifestyle.”

Industrial countries not only surrendered rare earths mining and processing to China, but gave up technological secrets too. That happened when China forced RE-dependent manufacturers to move their operations to China. After Apple transplanted some of its manufacturing to that country, China copied and reproduced the company’s products, at times outselling the iPhone with knock-offs.

A new book says self-imposed obstacles block U.S. self-sufficiency

Other intellectual property faces threats. “U.S. companies—Intematix, GE (Healthcare/MRI Division), Ford (Starter Motor Division), and Battery 1,2,3—have all added manufacturing capacity in China, and so has Japan’s Showa Denko, Santoku, and scores of other global electronics companies.”

RE dominance has also allowed China to lead the world in technology for electric vehicles, renewable energy and next-generation nuclear power. And America relies on its rival for defence: “Most of the U.S.’ advanced weapon systems procurement is 100% dependent on China for advanced metallurgical materials.”

Foreign dependency includes tantalum, “critical to the economy and national defense,” gallium, cobalt, uranium and the list goes on.

According to a just-published report from the U.S. Geological Survey, “in 2018, imports made up more than half of U.S apparent consumption for 48 non-fuel mineral commodities, and the U.S. was 100% net import-reliant for 18 of those.

“For 2018, critical minerals comprised 14 of the 18 mineral commodities with 100% net import reliance and 15 additional critical mineral commodities had a net import reliance greater than 50% of apparent consumption. The largest number of non-fuel mineral commodities were supplied to the U.S. from China, followed by Canada.”

The takeover of former TSX listing Uranium One by Russia’s state-owned Rosatom brings threats worse than most observers realized, the authors say. The acquisition granted the Russian government membership in trade organizations and therefore valuable intel formerly available only through espionage. Uranium One also gives Russia the ability to curtail future American uranium production and use its influence on Kazakhstan, the world’s top producer, to flood the U.S. with cheaper, subsidized supply. That could put both U.S. production and processing out of business in a tactic reminiscent of China’s RE machinations.

China’s communist government uses a “debt trap” model of economic development and finance which proffers substantial financing to developing countries in exchange for an encumbrance on their minerals resources and access to markets. This predatory model has been particularly effective in countries characterized by weak rule of law and authoritarian regimes.—Ned Mamula
and Ann Bridges

The Chinese “are now masters at securing and controlling core natural resources globally, especially minerals.” The country uses long-term contracts, equity investments and joint ventures, as well as the “debt trap” that provides “substantial financing to developing countries in exchange for an encumbrance on their minerals resources and access to markets. This predatory model has been particularly effective in countries characterized by weak rule of law and authoritarian regimes.”

The U.S., meanwhile, suffers not only from naivete and short-term thinking, but from self-induced challenges. The authors devote an entire chapter to Alaska’s Pebble project, maybe the world’s largest undeveloped copper-gold-molybdenum deposit. After more than two decades and over $150 million in spending, “Pebble is still more about politics than geology, much less mining the minerals known to exist there.”

The story stands out as “the classic cautionary tale in U.S. history of how a powerful federal regulatory agency can go rogue and impose its will on an unsuspecting permit applicant.”

Suggestions to alleviate these ills include streamlining the permitting process, among other recommendations to open up domestic production and re-build supply chains. One of the authors’ more interesting ideas concerns teaming up with environmental activists to promote ethical green supply chains that would shut out conflict minerals.

The book can be repetitious and sometimes overly emphatic with bold-faced typographical shouting. The manuscript’s also cluttered with a few questionable information sources and excerpts from a novel that would have been better left unwritten. The portrayal of Canada as a role model, moreover, might induce bitter laughter from this side of the border. But Groundbreaking offers a vital message to general readers. In doing so, it could reinforce a growing awareness in the U.S. about the need to minimize foreign dependency.

Saville Resources options Quebec nickel-copper-cobalt property to Astorius Resources

March 1st, 2019

by Greg Klein | March 1, 2019

By granting an option on its James Bay-region Covette property, Saville Resources TSXV:SRE stands to gain a cash infusion while another company works the project. Under the agreement, Astorius Resources TSXV:ASQ may acquire 100% of the nickel-copper-cobalt property by paying $1.25 million over three years and spending $300,000 by February 2021. Saville retains a 2% NSR.

Covette sits 10 kilometres north of the all-weather
Trans-Taiga road and adjacent powerline.

Previous work on Covette includes a 2016 VTEM survey and early-stage field work in 2017 and 2018, which included grab samples grading up to 0.09% copper and 0.19% nickel. Samples from outcrop showed up to 1.2% zinc, 68.7 ppm silver, 0.15% copper and 0.19% nickel.

In July Saville filed a 43-101 technical report recommending detailed mapping, surface sampling, channel sampling and further geophysics.

Saville’s focus remains the Niobium claim group in northern Quebec, a 75% earn-in from Commerce Resources TSXV:CCE, whose Ashram rare earths deposit a few kilometres away advances towards pre-feasibility. Autumn work on the Saville project found 22 boulder samples above 0.7% Nb2O5, with one peaking at 1.5%. Fourteen of the samples exceeded 0.8% Nb2O5 and brought encouraging tantalum results.

The program included a ground magnetic survey and also opened up a new target area where one standout boulder sample graded 1.28% Nb2O5 and 260 ppm Ta2O5, while another showed 0.88% Nb2O5 and 1,080 ppm Ta2O5.

In late December Saville closed a private placement first tranche of $311,919.

Periodic table: New version warns of elements that are endangered

Periodic table New version warns of elements that are endangered

It is amazing to think that everything around us is made up from just 90 building blocks—the naturally occurring chemical elements. Dmitri Mendeleev put the 63 known during his time into order and published his first version of what we now recognize as the periodic table in 1869. In that year, the American Civil War was just over, Germany was about to be unified, Tolstoy published War and Peace and the Suez Canal was opened.

There are now 118 known elements but only 90 that occur in nature. The rest are mostly super-heavy substances that have been created in laboratories in recent decades through nuclear reactions and rapidly decay into one or more of the natural elements.

Where each of these natural elements sits in the periodic table allows us to know immediately a great deal about how it will behave. To commemorate the 150th anniversary of this amazing resource, UNESCO has proclaimed 2019 as the International Year of the Periodic Table.

Periodic table New version warns of elements that are endangered

As part of the celebrations, the European Chemical Society has published a completely new version of the periodic table. (See main image.) It is designed to give an eye-catching message about sustainable development. Based on an original idea in the 1970s from the American chemist William Sheehan, the table has been completely redrawn so that the area occupied by each element represents its abundance on a log scale.

Red for danger

Each area of the new table has been colour-coded to indicate its vulnerability. In most cases, elements are not lost but, as we use them, they become dissipated and much less easy to recover. Red indicates that dissipation will make the elements much less readily available in 100 years or less—that’s helium (He), silver (Ag), tellurium (Te), gallium (Ga), germanium (Ge), strontium (Sr), yttrium (Y), zinc (Zn), indium (In), arsenic (As), hafnium (Hf) and tantalum (Ta).

To give just a couple of examples, helium is used to cool the magnets in MRI scanners and to dilute oxygen for deep-sea diving. Vital rods in nuclear reactors use hafnium. Strontium salts are added to fireworks and flares to produce vivid red colours. Yttrium is a component of camera lenses to make them shock- and heat-resistant. It is also used in lasers and alloys. Gallium, meanwhile, is used to make very high-quality mirrors, light-emitting diodes and solar cells.

Meanwhile, the orange and yellow areas on the new periodic table anticipate problems caused by increased use of these elements. Green means that plenty is available—including the likes of oxygen (O), hydrogen (H), aluminium (Al) and calcium (Ca).

Four elements—tin (Sn), tantalum (Ta), tungsten (W) and gold (Au)—are coloured in black because they often come from conflict minerals; that is, from mines where wars are fought over their ownership. They can all be more ethically sourced, so it’s intended as a reminder that manufacturers must carefully trace their origin to be sure that people did not die in order to provide the minerals in question.

Smartphone shortages

Out of the 90 elements, 31 carry a smartphone symbol reflecting the fact that they are all contained in these devices. This includes all four of the elements from conflict minerals and another six with projected useful lifetimes of less than 100 years.

Let us consider indium (In), for instance, which is coloured red on the table. Every touch screen contains a transparent conducting layer of indium tin oxide. There is quite a lot of indium, but it is already highly dispersed. It is a byproduct of zinc manufacture, but there is only enough from that source for about 20 years. Then the price will start to rise quickly unless we do something to preserve current stocks.

The three main possibilities are: replace, recycle or use less. Huge efforts are being made to find alternative materials based on Earth-abundant elements. Reclaiming indium from used screens is possible and being attempted. But when we look at the periodic table and the very precious nature of so many of the elements, can we possibly justify changing our phone every two or so years?

At present over one million phones are traded every month in the UK alone, as well as 10 million in Europe and 12 million in the U.S.

At present over one million phones are traded every month in the UK alone, as well as 10 million in Europe and 12 million in the U.S. When we trade in our smartphones, many of them go to the developing world initially for reuse. Most end up in landfill sites or undergo attempts to extract a few of the elements under appalling conditions. The other elements remain in acidic brews. Along with the very many that lie around in drawers, this is how the elements in mobile phones become dissipated.

The number of phones we trade in could be greatly reduced and lower the demand on limited resources such as indium. In this context, the recent Apple profit warning, partly due to customers replacing their iPhones slightly less frequently, was at least a sign of improvement.

But as the new version of the periodic table underlines, we must do all we can to conserve and recycle the 90 precious building blocks that make up our wonderfully diverse world. If we don’t start taking these problems more seriously, many of the objects and technologies that we now take for granted may become relics of a more abundant age a few generations from now—or available only to richer people.

92 Resources plans 2019 advancement of Canadian energy metals projects

January 22nd, 2019

by Greg Klein | January 22, 2019

With a portfolio that features lithium projects in Quebec along with vanadium and frac sand properties in British Columbia, 92 Resources TSXV:NTY now has its new year agenda in preparation. Taking precedence will be the FCI claims, a recent acquisition that enhances the company’s adjacent Corvette lithium project in Quebec’s James Bay region.

92 Resources plans 2019 advancement of Canadian energy metals projects

High-grade channel sampling has brought
Corvette’s CV1 pegmatite to the drill-ready stage.

Under a 75% earn-in, 92 has a year one spending commitment of $250,000 on FCI. The company has been reviewing historic data while working with operator Osisko Mining TSX:OSK to plan a surface program for the spring and summer. Following that will be a new field campaign at Corvette to precede the first-ever drill program on the two bordering properties.

Encouraging developments from Corvette last year include channel sampling on the CV1 pegmatite that revealed lithium grading as high as 2.28% Li2O over 6 metres and 1.54% over 8 metres, along with tantalum results. The team discovered two more spodumene-bearing pegmatites that suggest a potentially large mineralizing system along strike and at depth, 92 reported. A substantial staking expansion to Corvette along with the FCI earn-in covers about 15 kilometres of potential strike.

Looking at other possible sources of Quebec lithium, 92 also has field programs planned for the Pontax, Eastman and Lac du Beryl properties. Pontax grab samples have graded up to 0.94% Li2O and 520 ppm Ta2O5.

Additionally, the 2019 agenda calls for surface sampling on the Silver Sands vanadium prospect acquired in B.C. last November. The property features regionally mapped rock units that potentially host vanadium-bearing horizons.

Last year 92 filed a 43-101 technical report for its Golden frac sand project in southern B.C., adjacent to Northern Silica’s high-grade Moberly silica mine.

In the Northwest Territories, 92 holds an interest in the Hidden Lake lithium project, the subject of a maiden drill program last year by Far Resources CSE:FAT. The latter company has completed 60% of a 90% earn-in from 92.

92 closed a private placement of $618,000 in late December.

DRC on the brink

January 3rd, 2019

The Congo’s increasing instability heightens critical minerals concern

by Greg Klein

Update: In what’s been called the DRC’s first peaceful transfer of power since 1960, Felix Tshisekedi was sworn in as president on January 24. That follows a controversial election in which two parts of the country had voting delayed until March and supporters of candidate Martin Fayulu accused the electoral commission of rigging the results in favour of Tshisekedi, who they say struck a pact with outgoing president Joseph Kabila. Catholic church observers had earlier disputed the outcome and Fayulu asked the Constitutional Court to order a recount. “The court, made up of nine judges, is considered by the opposition to be friendly to Kabila, and Fayulu has said he is not confident that it will rule in his favour,” Al Jazeera reported.

 

This is the place that inspired the term “crimes against humanity.” As a timely new book points out, American writer George Washington Williams coined that phrase in 1890 after witnessing the cruel rapaciousness of Belgian King Leopold II’s rubber plantations in the country now known as the Democratic Republic of Congo. After rubber, the land and its people were exploited for ivory, copper, uranium, diamonds, oil, ivory, timber, gold and—of increasing concern for Westerners remote from the humanitarian plight—cobalt, tin, tungsten and tantalum. Controversy over recent elections now threatens the DRC with even greater unrest, possibly full-scale war.

The Congo’s increasing instability heightens critical minerals concern

The country of 85 million people typically changes governments through coup, rebellion or sham elections. Outgoing president Joseph Kabila ruled unconstitutionally since December 2016, when his mandate ended. He belatedly scheduled an election for 2017, then postponed it to last December 23 before pushing that date back a week. The December 30 vote took place under chaotic conditions and with about 1.25 million voters excluded until March, a decision rationalized by the Ebola epidemic in the northeast and violence in a western city.

The epidemic marks the second-worst Ebola outbreak in history, the DRC’s tenth since 1976 and the country’s second this year. Although the government delayed regional voting on short notice, the health ministry officially recognized the current epidemic on August 1.

Responsible for hundreds of deaths so far, this outbreak takes place amid violence targeting aid workers as well as the local population. Like other parts of the country, the region has dozens of military groups fighting government forces for control, and each other over ethnic rivalries and natural resources. The resources are often mined with forced labour to fund more bloodshed.

With no say from two areas that reportedly support the opposition, a new president could take office by January 18. Already, incumbent and opposition parties have both claimed victory.

Kabila chose Emmanuel Ramazani Shadary as his successor candidate but didn’t rule out a future bid to regain the president’s office himself.

Election controversy contributed to additional violent protests in a month that had already experienced over a hundred deaths through ethnic warfare as well as battles between police and protesters. Yet that casualty toll isn’t high by DRC standards.

Published just weeks before the election, Congo Stories by John Prendergast and Fidel Bafilemba relates a harrowing story of a country the size of Western Europe that’s fabulously rich in minerals but desperately poor thanks to home-grown kleptocracies and foreign opportunists. Forced labour, war and atrocities provide a deeply disturbing backdrop to the story of conflict minerals.

According to 2017 numbers from the U.S. Geological Survey, the DRC supplied about 58% of global cobalt, 34.5% of tin and 28.5% of tantalum. The U.S. has labelled all three as critical metals. Tin and tantalum, along with tungsten and gold, are currently the DRC’s chief conflict metals, Prendergast and Bafilemba note. In addition to Congo tantalum, the world got 30% of its supply from DRC neighbour Rwanda, another source of conflict minerals.

Prendergast and Bafilemba outline the horror of the 1990s Rwandan Tutsi-Hutu bloodshed pouring into the Congo, making the country the flashpoint of two African wars that involved up to 10 nations and 30 local militias. During that time armies turned “mass rape, child soldier recruitment, and village burnings into routine practice.”

For soldiers controlling vast swatches of mineral-rich turf, rising prices for gold and the 3Ts (tantalum, tungsten and tin) provided an opportunity “too lucrative to ignore.” Brutal mining and export operations drew in “war criminals, militias, smugglers, merchants, military officers, and government officials,” Prendergast and Bafilemba write. “Beyond the war zones, the networks involved mining corporations, front companies, traffickers, banks, arms dealers, and others in the international system that benefit from theft and money laundering.”

DRC leaders did well too. “Mobutu Sese Seko, who ruled Congo from 1965 to 1997, is seen as the ‘inventor of the modern kleptocracy, or government by theft,’” Prendergast and Bafilemba state. “At the time of our writing in mid-2018, President Joseph Kabila is perfecting the kleptocratic arts.”

The Congo’s increasing instability heightens critical minerals concern

Westerners might be even more disturbed to learn of other beneficiaries: Consumers “who are usually completely unaware that our purchases of cell phones, computers, jewelry, video games, cameras, cars, and so many other products are helping fuel violence halfway around the world, not comprehending or appreciating the fact that our standard of living and modern conveniences are in some ways made possible and less expensive by the suffering of others.”

Not all DRC mines, even the artisanal operations, are considered conflict sources. But increasing instability could threaten legitimate supply, even the operations of major companies.

The example of Glencore subsidiary Katanga Mining TSX:KAT, furthermore, shows at least one major failing to rise above the country’s endemic problems. In mid-December Katanga and its officers agreed to pay the Ontario Securities Commission a settlement, penalties and costs totalling $36.25 million for a number of infractions between 2012 and 2017.

Katanga admitted to overstating copper production and inventories, and also failing to disclose the material risk of DRC corruption. That included “the nature and extent of Katanga’s reliance on individuals and entities associated with Dan Gertler, Gertler’s close relationship with Joseph Kabila, the president of the DRC, and allegations of Gertler’s possible involvement in corrupt activities in the DRC.”

In December 2017 the U.S. government imposed sanctions on Gertler, a member of a prominent Israeli diamond merchant family, describing him as a “billionaire who has amassed his fortune through hundreds of millions of dollars’ worth of opaque and corrupt mining and oil deals” in the DRC.

“As a result, between 2010 and 2012 alone, the DRC reportedly lost over $1.36 billion in revenues from the underpricing of mining assets that were sold to offshore companies linked to Gertler.”

Just one day before imposing sanctions, U.S. President Donald Trump signed an executive order calling for a “federal strategy to ensure secure and reliable supplies of critical minerals.” Approaches to be considered include amassing more geoscientific data, developing alternatives to critical minerals, recycling and reprocessing, as well as “options for accessing and developing critical minerals through investment and trade with our allies and partners.”

Unofficial DRC election results could arrive by January 6. Official standings are due January 15, with the new president scheduled to take office three days later. Should the Congo see a peaceful change of government, that would be the DRC’s first such event since the country gained independence in 1960.

 

January 7 update: The DRC’s electoral commission asked for patience as interim voting results, expected on January 6, were delayed. Internet and text-messaging services as well as two TV outlets remain out of service, having been shut down since the December 30 election ostensibly to prevent the spread of false results. On January 4 the U.S. sent 80 troops into nearby Gabon in readiness to move into the DRC should post-election violence threaten American diplomatic personnel and property. The United Nations reported that violence in the western DRC city of Yumbi over the last month has driven about 16,000 refugees across the border into the Republic of Congo, also known as Congo-Brazzaville.

Niobium-tantalum in Quebec

December 5th, 2018

Successful sampling readies Saville Resources to drill for critical metals

by Greg Klein

“Building momentum” is the way Saville Resources TSXV:SRE president Mike Hodge puts it. Steady progress, shown most recently through another encouraging sampling program, puts the company’s early-stage niobium-tantalum project in Quebec on track for drilling this winter. Assays so far have the company hopeful about proving up a maiden resource in this mining-friendly jurisdiction next door to a country increasingly concerned about sourcing critical metals.

Successful sampling readies Saville Resources to drill for critical metals

Conducted by Dahrouge Geological Consulting, the fall
program brought the Niobium claim group to drill-ready status.

The autumn field program met all of its objectives, Hodge enthuses. Twenty-two boulder samples surpassed 0.7% Nb2O5, with 14 of them exceeding 0.8% and one peaking at 1.5%. Tantalum made its presence known too. Those same 14 niobium samples also graded between 160 ppm and 1,080 ppm Ta2O5.

The project gained yet another target, where boulders reached 0.88% and 1.28% Nb2O5. A ground magnetics survey highlighted the prospectivity of the Moira area, already the location of exceptionally high-grade samples. In all, the results show a drill-ready project that should see action this winter.

Saville holds a 75% earn-in from Commerce Resources TSXV:CCE on the Niobium claim group, a 1,223-hectare package on the latter company’s Eldor property in Quebec. Just a few kilometres from the Niobium project and with obvious synergistic potential for Saville, Commerce has its Ashram rare earths deposit moving towards pre-feasibility. All this takes place in a province that demonstrates its support for mining through a number of initiatives, including direct investment and the Plan Nord infrastructure program. The northeastern Quebec region has two treaties in place that clearly define procedures for native consultation. Saville’s three-quarters stake in the Niobium claim group calls for $5 million in work over five years.

A 43-101 technical report filed in September followed field programs by previous companies including 41 holes totalling 8,175 metres drilled by Commerce. In addition to niobium-tantalum, the report noted phosphate and fluorspar as potential secondary commodities.

Some of the standout results from previous sampling came from the property’s as-yet undrilled Miranna area, where boulder samples graded as high as 2.75%, 4.24%, 4.3% and an exceptional 5.93% Nb2O5.

Other locations have been drilled, but not since 2010. Some 17 holes and 4,328 metres on the Southeast area brought near-surface highlights that include:

  • 0.82% Nb2O5 over 21.89 metres, starting at 58.93 metres in downhole depth

  • 0.72% over 21.35 metres, starting at 4.22 metres
  • (including 0.9% over 4.78 metres)

  • 0.72% over 17.35 metres, starting at 70 metres

  • 0.71% over 15.33 metres, starting at 55.1 metres

True widths were unavailable. Southeast results also showed tantalum and phosphate, as well as suggesting a possible fluorspar zone.

A wide, near-surface interval from the Northwest area showed:

  • 0.46% Nb2O5 over 46.88 metres, starting at 30.65 metres
  • (including 0.61% over 11.96 metres)
Successful sampling readies Saville Resources to drill for critical metals

Surface outcrops and near-surface core
produce encouraging grades for Saville Resources.

As in the Southeast, the Northwest area showed encouraging signs of tantalum and phosphate. But tantalum came through most strongly in the property’s Star Trench area, with results as high as 1,810 ppm Ta2O5 (with 1.5% Nb2O5) over 0.52 metres, as well as 2,220 ppm Ta2O5 (with 1.69% Nb2O5, and phosphate grading 20.5% P2O5) over 0.31 metres.

Another area gains greater prominence too, thanks to this autumn’s ground magnetics survey. A strong anomaly at the Moira target, about 250 metres north of Miranna, coincides with several overlapping boulder trains that suggest Moira could be one of several possible sources of mineralization.

And a new, yet-to-be-named area gave up two of the fall program’s best assays. About 400 metres south of the drill area, the new target produced boulder samples hitting 1.28% Nb2O5 and 260 ppm Ta2O5, along with 0.88% Nb2O5 and 1,080 ppm Ta2O5.

Intriguingly, glacial ice suggests the two rocks, found about 100 metres apart, originated in an area farther southeast that’s had very little attention so far.

Saville also holds the 3,370-hectare Covette project in Quebec’s James Bay region, where last summer’s field program found surface samples including 1.2% zinc and 68.7 g/t silver. Three other samples returned nickel values ranging from 0.13% to 0.19%.

Work focused on a highly conductive area identified by a 2016 VTEM survey. Samples gathered in 2017 included grades of 0.18% nickel, 0.09% copper and 87 ppm cobalt. One historic, non-43-101 grab sample brought 4.7% molybdenum, 0.73% bismuth, 0.09% lead and 6 g/t silver, while another historic sample returned 1.2 g/t silver and 0.18% copper.

As for niobium, it’s considered a critical metal by the American government for its use in steels and super-alloys necessary for jet engine components, rocket sub-assemblies, and heat-resisting and combustion equipment, according to the U.S. Geological Survey. Almost 90% of last year’s world production came from Brazil, where new president Jair Bolsonaro has expressed concern about increasing Chinese ownership of resources.

Also a component of military super-alloys, tantalum additionally plays a vital role in personal electronics including phones and computers. The U.S. imports its entire supply of tantalum. About 60% of last year’s world production came from the troubled countries of Rwanda and the Democratic Republic of Congo.

With the advantages of markets, jurisdiction and geology, Hodge looks forward to winter drilling. “We’ve now got about 20 targets that we can go after,” he says. “One priority would be to define the Southeast area because we’ve got such good niobium numbers there. On getting a potential inferred resource, we’d go after Miranna or Moira and the untested targets. We’re looking forward to a busy, productive season.”

U.S. military’s new super-alloy would increase American dependence on a critical metal

November 26th, 2018

by Greg Klein | November 26, 2018

Researchers hail it as the material most similar to vibranium, the wondrous substance associated with the land of Wakanda and Captain America’s shield—except that this stuff actually exists outside of comic books, movies and games.

Described as a “super-strong alloy of copper and tantalum that can withstand extreme impact and temperature,” it was concocted by boffins from the U.S. Army Research Laboratory and Arizona State University.

Its features could prove useful in space exploration, weaponry, and protection for soldiers and military vehicles, said Kristopher Darling, a materials scientist with ARL.

The alloy’s strength and conductivity offer possibilities for other metals too. “Materials based on iron or aluminum for instance could be used for protection and lethality applications,” he added.

The copper-tantalum alloy “can withstand high rates of impact and temperatures in excess of 80% of their melting point, which is higher than 1,073 kelvin or greater than 1,472 degrees Fahrenheit, with very little change in its microstructure,” ARL explained.

The multidisciplinary team developed the new alloy originally to replace copper-beryllium. Although that alloy’s also known for its strength, conductivity, hardness and resistance to corrosion, exposure to beryllium can cause a serious lung condition.

Should the new alloy prove a practical substitute, it would also substitute one critical metal for another. Both beryllium and tantalum can be found in a list of 35 critical minerals drafted by the U.S. last February and confirmed in May.

Although the U.S. holds about 60% of the world’s known beryllium resources, the country relies entirely on imports for tantalum, according to U.S. Geological Survey data.

American president Donald Trump has called for a national strategy to reduce the country’s dependence on critical minerals from potentially hostile or unstable jurisdictions.

92 Resources adds B.C. vanadium project to Quebec lithium package

Expanding its portfolio of energy metals, 92 Resources TSXV:NTY moves into a vanadium exploration region in eastern British Columbia. The 3,735-hectare Silver Sands property sits directly east of Ethos Gold’s (TSXV:ECC) Pine Pass project, where a recent trenching program brought results including 0.48% V2O5 over 130 metres, part of a cumulative, non-continuous extent averaging 0.43% V2O5 over 218 metres. Ethos reports approximately 20 kilometres of subcrop strike distance on the property.

Silver Sands hosts similar features, 92 states. The company interprets the property’s rock types as “an adjacent thrust sheet, of analogous or identical lithologies” to those at Pine Pass, with both properties hosting “regionally mapped early Triassic-aged Spray River Group rocks (containing the Toad River and Grayling formations), which have been known to host vanadium-bearing horizons associated with phosphatic shales.

“Specifically, the project is host to the Lemoray phosphate prospect, a phosphatic horizon which has been historically noted in the academic literature, but its relation to vanadium mineralization has not yet been tested.”

92 hopes to begin initial field work once snow melts, says Neil McCallum of Dahrouge Geological Consulting.

92 president/CEO Adrian Lamoureux said the acquisition suits the company’s strategic plans. “With a focus on future energy metals such as lithium and frac sand, we have now positioned the company with a key vanadium asset in a mine-friendly jurisdiction. We will now evaluate and put together our winter exploration plans that should contain our Phase I drill program at the Corvette-FCI lithium project in Quebec.”

An option signed in September with Osisko Mining TSX:OSK gives 92 a 75% earn-in on the 10,000-hectare FCI claims adjacent to the flagship Corvette project. Corvette channel samples released that month averaged 1.35% Li2O, along with tantalum averaging 109 ppm Ta2O5.

Vanadium prices now approach an all-time high, having jumped over 550% since September 2016, Lamoureux added. Chinese steel accounts for most demand but vanadium-redox flow batteries offer additional future potential.

Pine Pass regional infrastructure includes Highway 97, the Canadian National Railway, transmission lines and natural gas pipelines.

92 gets Silver Sands by paying staking costs of $15,000, while the vendor keeps a 2% NSR.

In addition to Silver Sands and Corvette, the company holds three other Quebec lithium projects, Pontax, Eastmain and Lac du Beryl, as well as the Golden frac sand project in southern B.C.
