92 Resources begins metallurgical tests on NWT lithium

March 28th, 2017

by Greg Klein | March 28, 2017

A Northwest Territories lithium project gets its first-ever metallurgical studies as 92 Resources TSXV:NTY announced a two-phase program on March 28. The 1,659-hectare Hidden Lake property underwent channel sampling last year on four of six known lithium-bearing spodumene dykes, with the best intercept showing:

  • 1.58% Li2O and 31 ppm Ta2O5 over 8.78 metres

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

Hidden Lake’s metallurgical tests follow
last year’s successful sampling program.

The met program’s first phase examines the property’s spodumene and waste materials, leading to a mineral processing phase intended to separate the two and produce a high-grade concentrate.

Material from four pegmatites will be evaluated separately and, if no significant differences are found, a single composite will undergo processing tests. Those tests would include grinding, heavy liquid separation, magnetic separation and flotation. Plans then call for a preliminary flowsheet and a small amount of potentially marketable spodumene concentrate.

The program will also evaluate potential tantalum recovery.

Hidden Lake has all-weather road access to Yellowknife, 45 kilometres southwest. Carrying out the tests will be SGS Canada, which has considerable experience in spodumene pegmatite processing, 92 Resources stated.

In northern Quebec, 92 Resources has initial lithium exploration planned for Pontax, a 5,536-hectare property in a district known for spodumene-bearing pegmatites as well as gold potential.

Earlier this month the company expanded its Golden frac sand project from 807 hectares to 3,211 hectares. The southeastern British Columbia property sits adjacent to the Moberly silica sand project, now being redeveloped into a frac sand operation and among the assets sought by Northern Silica in its takeover bid for Heemskirk Consolidated.

Late last month 92 Resources closed an oversubscribed private placement of $895,199.

Equitorial Exploration files 43-101 for NWT lithium project

LNPG’s mountainous terrain could undergo drilling this year.

Also referred to as LNPG or the Li property, the project underwent sampling last year, with results reported in October and September.

Field work traced lithium-cesium-tantalum pegmatite dyke swarms over a combined length of 13 kilometres on the property’s mountainous terrain, the company stated. The dykes’ vertical extent has been traced for 300 metres through natural exposure and drilling in 2007. “Where sampled, each dyke swarm is up to 52.6 metres wide and contains multiple dykes that range from 0.2 to 10 metres in width.”

This year Equitorial anticipates resampling the 2007 core, drilling, channel sampling, mapping and prospecting.

Located in the southern NWT just east of the Yukon border, LNPG sits about 30 kilometres from the former Cantung tungsten mine. In addition to the NWT hardrock project, Equitorial holds two Nevada lithium brine properties, Tule and Gerlach, proximal to the Tesla Gigafactory #1.

Commerce Resources and TUGLIQ Energy ink MOU on wind power for Quebec rare earths project

March 1st, 2017

by Greg Klein | March 1, 2017

Looking at the dual benefits of cutting costs and cutting emissions, Commerce Resources TSXV:CCE and TUGLIQ Energy have signed a memorandum of understanding to assess the potential for wind energy on the Ashram rare earths project. Announced February 28, the MOU follows TUGLIQ’s preliminary evaluation of local and regional wind data proximal to the northern Quebec deposit that Commerce is advancing towards pre-feasibility. Funding for the wind energy study comes partly from the province’s Ministère de l’Énergie et des Ressources naturelles.

An independent power producer already active in northern Quebec, TUGLIQ operates a 3 MW wind turbine with energy storage that the company built in 2014 at Glencore’s Raglan mine. In the Northwest Territories, the Rio Tinto NYSE:RIO/Dominion Diamond TSX:DDC Diavik mine has been supplementing its diesel power with a four-turbine, 9.2 MW wind farm since 2012.

TUGLIQ’s Ashram study will consist of wind resource assessment, electrical system engineering and an integration study including assessment of greenhouse gas emission reductions.

“We are excited to be collaborating with TUGLIQ and to have the support of the Quebec government on this renewable resource project,” said Commerce president Chris Grove. “We look forward to evaluating this potential in much further detail. The potential to incorporate cost-effective renewable energy into the Ashram project only makes it that much more attractive for development.”

In mid-February the company closed a $1.71-million private placement that included $1 million from Ressources Québec, a subsidiary of the provincial government corporation Investissement Québec. The money will be used to complete Ashram’s pilot plant and produce REE and fluorite concentrates for companies that requested samples. Among them are Solvay, Mitsubishi, Treibacher, BASF, DKK, Albemarle and Blue Line.

Having reached PEA in 2012, the high-grade, near-surface deposit features an impressive distribution of magnet feed elements and relatively simple metallurgy, suggesting a potentially low-cost operation.

Quebec maintains its respected position as a mining jurisdiction, according to a Fraser Institute study released February 28. “Quebec ranks third in Canada and sixth globally—up from eighth spot last year—and is the only other Canadian jurisdiction [along with Saskatchewan and Manitoba] in the top 10 worldwide for overall investment attractiveness,” the FI stated.

In another rare metals project, Commerce holds the Upper Fir tantalum-niobium deposit in southeastern British Columbia, which reached PEA in 2011 and a resource update in 2013.

Province of Quebec invests in Commerce Resources’ Ashram rare earths project

February 17th, 2017

by Greg Klein | February 17, 2017

With potential customers waiting for rare earths concentrate samples, Commerce Resources TSXV:CCE closed a $1.71-million private placement on February 17 that included $1 million from Ressources Québec. A subsidiary of the provincial government corporation Investissement Québec, Ressources Québec “focuses on projects that have good return prospects and foster Québec’s economic development,” the organization says. “Its role is complementary to private funders.”

We are excited to have the support of the Quebec government with this investment from Ressources Québec. The province of Quebec continues to prove that it is one of the most attractive jurisdictions to develop a mineral project. —Chris Grove,
president of Commerce Resources

“We are excited to have the support of the Quebec government with this investment from Ressources Québec,” Commerce president Chris Grove stated. “The province of Quebec continues to prove that it is one of the most attractive jurisdictions to develop a mineral project. We are excited to be advancing our Ashram project with this financing.”

The private placement will be used to complete the project’s pilot plant, to produce samples of REE and fluorite concentrates, and for general working capital. Among companies requesting REE samples are Solvay, Mitsubishi, Treibacher, BASF, DKK, Albemarle and Blue Line.

The money comes in addition to a three-year, $300,000 environmental grant from the province to optimize tailings management.

Ashram’s high-grade, near-surface deposit benefits from relatively simple metallurgy, suggesting a potentially low-cost operation with an impressive distribution of magnet feed elements. Now moving towards pre-feas, the project reached PEA in 2012.

Commerce also holds the Upper Fir tantalum-niobium deposit in southeastern British Columbia, which reached PEA in 2011 and a resource update in 2013.

commodities of which the U.S. imported more than 50% of its supply in 2016.

Lacking any domestic sources at all, the United States imported 100% of its supply of 20 minerals last year, the USGS reports. That number increased from 19 the previous year and 11 in 1984. Included in the 2016 list were rare earths, manganese and niobium, “which are among a suite of materials often designated as ‘critical’ or ‘strategic’ because they are essential to the economy and their supply may be disrupted.”

U.S. increases its dependence on critical mineral imports

Imports of rare earth compounds and metals increased 6% over 2015, although the value dropped from $160 million to $120 million. China supplied 72% directly, with other imports coming from Estonia (7%), France (5%), Japan (5%) and other countries (11%).

But the Estonian, French and Japanese material was derived from concentrates produced in China and elsewhere, the USGS added.

American imports of tantalum increased about 40% over 2015. The USGS attributed about 37% of 2016 global production to the Democratic Republic of Congo and 32% to Rwanda. Estimates reverse those numbers for the previous year.

An alphabetical list of the 20 minerals follows, with rare earths, scandium and yttrium each comprising a separate category:

  • arsenic
  • asbestos
  • cesium
  • fluorspar
  • gallium
  • graphite
  • indium
  • manganese
  • mica
  • niobium
  • quartz crystal
  • rare earths
  • rubidium
  • scandium
  • strontium
  • tantalum
  • thallium
  • thorium
  • vanadium
  • yttrium

The report listed 50 minerals for which the U.S. imported over half of its supply. Overall China was the largest exporter, with Canada running second.

The Ashram advantage

January 30th, 2017

Commerce Resources prepares for a rare earths paradigm shift

by Greg Klein

The appeal to Western markets is obvious—an advanced, low-cost rare earths project in a friendly jurisdiction. So even before the recent military build-up in the South China Sea, Commerce Resources TSXV:CCE experienced an increase in American requests for concentrate samples from its northern Quebec Ashram deposit. With the U.S. Navy now challenging Chinese territorial aggression, the confrontation seems to pit two superpowers against each other. But what does that really indicate?

It’s actually “one lonely small old Russian-built carrier against three U.S. Nimitz-class supercarriers,” Commerce president Chris Grove points out. “So when Beijing says it’s going to take off the gloves, I think they’re referring to trade.”

Commerce Resources prepares for a rare earths paradigm shift

That brings to mind the Senkaku incident, a much smaller 2010 confrontation in the same region that prompted China to cut off rare earths exports to Japan, sending global supply chains into turmoil and prices soaring. A possible Senkaku redux is one of a number of aspects to a global paradigm shift that Grove sees coming, to the benefit of Western industry in general and Ashram in particular.

The U.S. might easily outgun China, but China produces about 90% of the world’s rare earths. They’re essential to several defence needs, “a fact that really drives certain people in the U.S. absolutely apoplectic,” says Grove.

While Westerners have struggled to compete with China on costs, prices mean little to the U.S. Department of Defense, which last year began putting money behind potential domestic processors, Grove says. That support complements a multi-faceted advantage that the West is gaining over China, he explains. The latter country struggles with rising labour costs and the need to finally address its environmental woes. Meanwhile Western countries offset their labour costs with technological innovation and maintain the world’s highest environmental standards.

Even putting aside defence, demand for rare earths continues to grow with another global development. The international commitment to address climate change through clean energy, exemplified by the Paris Agreement, increases rare earths demand for numerous applications ranging from EVs to wind turbines.

In a research report last year, Chris Berry noted that “REE usage continues to grow at a pace well above global GDP growth with demand CAGRs growing anywhere from 4% to 8%, with permanent magnet demand forecast to lead this charge to 2020.”

Commerce Resources prepares for a rare earths paradigm shift

Ashram has undergone another 9,200 metres since
its resource estimate, often hitting even higher grades.

Clearly there’s a market for non-Chinese sources. And Grove sees Ashram uniquely positioned to help serve that market. Certainly others have failed but, he emphasizes, they lacked Ashram’s benefits of mineralogy, metallurgy, grade and jurisdiction—all of which add up to lower costs.

The project reached PEA in 2012, with an amended PEA in 2015. Since then the company’s been busy on multiple fronts as it advances towards pre-feasibility.

Ashram’s advantage begins with its relatively simple mineralogy, with carbonatite host rock and rare earths within the minerals monazite, bastnasite and xenotime, which dominate commercial REE processing.

Pilot plant metallurgical tests have quadrupled the PEA’s concentrate grade, producing 41% total rare earth oxides and 43% TREO, both at 71% recovery. That puts the grade well within the range of commercial producers and does so through a single-leach process that simplifies the flowsheet.

Requests for concentrate samples have come from Solvay, Mitsubishi, Treibacher, BASF, DKK, Albemarle and Blue Line, among others covered by non-disclosure agreements.

Metallurgy has also found a potential fluorspar byproduct, offering an advantage to both revenue and opex. Grove credits Glencore Canada’s interest in fluorspar with the willingness of its NorFalco Sales division to supply Commerce with sulphuric acid on highly favourable terms.

Proud as he is of Ashram’s high-grade, near-surface resource, Grove anticipates an even more impressive upgrade. The current estimate uses a 1.25% cutoff to show:

  • measured: 1.59 million tonnes averaging 1.77% total rare earth oxides

  • indicated: 27.67 million tonnes averaging 1.9% TREO

  • inferred: 219.8 million tonnes averaging 1.88% TREO

Commerce has since drilled another 9,200 metres, mostly infill but always with some stepout holes as well. “In all those drill programs, we always hit mineralized material in the stepouts, we always encountered less waste rock at surface than was modelled in the resource and we always hit zones that were higher than the average grade,” he says.

Ashram’s magnet feed distribution also has Grove enthused. Overall, the deposit ranks with the largest producers for praseodymium, neodymium, terbium and dysprosium. Ashram’s medium-to-heavy REO resource, moreover, surpasses the producers for those elements. And, as Grove points out, those are critical elements. Efforts to find substitutes for magnet REEs have failed.

Companies with higher operating costs are probably praying for higher prices. Commerce Resources doesn’t need them. We still have a margin at today’s prices.—Chris Grove

Benefiting both Ashram’s opex and the environment would be wind energy, currently being studied for the project. Commerce’s environmental commitment as well as its community outreach have been recognized by the e3 Plus Award for social responsibility from l’Association de l’exploration minière du Québec.

The company has also received a $300,000 provincial grant to optimize tailings management, funding that shows Quebec’s commitment to mining as well as the environment. Grove calls the province “a fantastic jurisdiction,” one that invests directly in companies through Ressources Québec and makes tangible progress on the visionary Plan Nord infrastructure program.

Following a private placement of up to $2.5 million offered last month, Grove looks forward to a number of near-term milestones. Still to come are final assays from last year’s drilling. The agenda also calls for completing the pilot plant and filling requests for REE and fluorspar concentrate samples. The samples, Grove suggests, could spur interest in a JV or offtake agreement.

The Commerce quest for rare metals hasn’t been confined to rare earths. Last September sampling on the company’s property about a kilometre from Ashram found “spectacular” results up to 5.9% niobium pentoxide, described by Grove as “approximately double the grade of the largest and longest-running niobium producer’s head grade, CBMM’s Araxa deposit in Brazil.”

Commerce also holds the Blue River project in southeastern British Columbia. The property’s Upper Fir tantalum-niobium deposit reached PEA in 2011 and a resource update in 2013.

But Commerce remains very much focused on Ashram. Whether events in the South China Sea send RE prices soaring, Grove sees possible increases coming from producers boosting revenues. But, he emphasizes, Ashram doesn’t need higher prices. “Companies with higher operating costs are probably praying for higher prices,” he says. “Commerce Resources doesn’t need them. We still have a margin at today’s prices.”

Canadian International Minerals reconsiders niobium potential of B.C. REE project

Canadian International Minerals reconsiders niobium potential of B.C. REE project

A rare earths property in British Columbia’s Rocky Mountain rare metal belt gains new attention as Canadian International Minerals TSXV:CIN takes another look at previous assays. An 11-hole program on the Wicheeda alkaline-carbonatite project in 2011 targeted rare earths but the company didn’t consider the niobium results to be material info. On January 26, however, CIN released niobium assays from four 2011 holes, with highlights showing:

Hole CA-11-010

  • 0.188% Nb2O5 over 16.06 metres, starting at 171.8 metres in downhole depth
  • (including 0.27% over 6.3 metres)
  • (which includes 0.731% over 0.98 metres)

CA-11-014

  • 0.156% over 24.43 metres, starting at 173.23 metres
  • (including 0.217% over 9.57 metres)
  • (which includes 0.337% over 3.9 metres)

  • 0.226% over 37.6 metres, starting at 232.98 metres
  • (including 0.297% over 18.27 metres)
  • (which includes 0.321% over 8.48 metres)
  • (which includes 0.632% Nb2O5 and 158 ppm tantalum over 2.2 metres)

True widths weren’t available.

Formerly called the Carbo project, Wicheeda showed RE results in the range of 0.2% to 0.5% total rare earth oxides in most of the 11 holes sunk during 2011. The previous year’s campaign found significant RE mineralization in all nine holes, with one intercept hitting 1.43% TREO over 37.3 metres.

Adjacent to CIN’s Wicheeda, Spectrum Mining’s Wicheeda project holds an inferred 11.3 million tonnes averaging 2.5% TREO.

CIN noted two niobium deposits hosted in the Rocky Mountain rare metal belt. The Upper Fir deposit on Commerce Resources’ (TSXV:CCE) Blue River project holds an indicated 48.41 million tonnes averaging 0.161% Nb2O5 and 197 ppm Ta2O5. Located about 330 kilometres southeast of Wicheeda, Upper Fir also holds an inferred 5.4 million tonnes averaging 0.176% Nb2O5 and 191 ppm Ta2O5.

About 240 kilometres northwest of Wicheeda, Taseko Mines TSX:TKO brought the Aley project to pre-feas in 2014 with proven and probable reserves of 83.8 million tonnes averaging 0.5% Nb2O5.

CIN stated it “continues to re-evaluate the exploration targets for the Wicheeda project and will be investigating a number of partnership avenues in the coming weeks.”

In November the company released sample results from a due diligence program on its proposed Tisova acquisition, a former copper-polymetallic mine in the Czech Republic.

Arctic Star looks to B.C. for rare metals and rare earths

January 17th, 2017

by Greg Klein | January 17, 2017

A previously acquired property gets new attention as Arctic Star Exploration TSXV:ADD applies for a drill permit to search for niobium, tantalum and rare earth elements in central British Columbia.

Arctic Star looks to B.C. for rare metals and rare earths

Field work during 2010 on the 2,825-hectare CAP project found 481 to 981 parts per million niobium, 1,125 to 3,191 ppm zirconium, over 100 ppm lanthanum, over 100 ppm cerium and over 50 ppm neodymium. Two historic, non-43-101 samples returned strongly anomalous results of 0.13% and 0.1% rare earth elements, the company stated.

A circular magnetic anomaly of about three to five kilometres’ diameter could indicate a carbonatite or similar intrusion at depth, Arctic Star added. “Carbonatite-related deposits are a major host for rare metals, such as niobium and tantalum, and rare earth elements.”

Located about 80 kilometres from Prince George, CAP can be reached by logging roads during the summer and helicopter year-round.

In December the company closed a second tranche of financings totalling $1.47 million, including $300,000 of flow-through earmarked for CAP.

In November Arctic Star announced a JV with Margaret Lake Diamonds TSXV:DIA on their newly compiled Diagras property in the Northwest Territories’ diamondiferous Lac de Gras region.

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

November 28th, 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.

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.
