Saville Resources, Commerce Resources find more fluorspar in re-assayed core from Quebec niobium-tantalum project

Saville Resources, Commerce Resources find increased fluorspar mineralization in re-assayed core from Quebec niobium-tantalum project

A map approximates the fluorspar mineralized
trend found within the property’s wider niobium trend.

 

By focusing on some critical minerals another was neglected, these companies realized. Already aware of niobium, tantalum and phosphate, Saville Resources TSXV:SRE re-assayed core extracted last year and in 2008 on northern Quebec’s Niobium Claim Group project. The area in focus was the property’s Mallard prospect.

Located two kilometres from Commerce Resources’ (TSXV:CCE) advanced-stage Ashram rare earths-fluorspar deposit, Saville operates the earlier-stage, 1,223-hectare Niobium Claim Group on a 75% earn-in from Commerce.

Originally, only the highest-grade intervals were assayed for fluorine. But a review of two programs of historic drilling and Saville’s own 2019 Phase I campaign outlined a previously under-rated fluorspar trend within the project’s niobium trend. 

Saville Resources, Commerce Resources find increased fluorspar mineralization in re-assayed core from Quebec niobium-tantalum project

Fluorspar shows its true colours in this 2008 core.

A second look at selected intervals supports that analysis. The re-assayed intervals confirm “a broad and extensive fluorspar mineralized trend at Mallard, which extends for at least 600 metres along strike and is open to the northwest, southeast, down-dip, and is interpreted to continue to surface,” the companies stated. “The trend remains to be delineated significantly outside of the core Mallard area.”

One 2008 intercept originally graded 30.7% CaF2 over 22.3 metres. New assays show that interval to be part of a wider zone grading 21.5% over 38.6 metres. Additionally, the intercept shows niobium, tantalum and phosphate at moderate grades of 0.36% Nb2O5, 103 ppm Ta2O5 and 5.3% P2O5.

Another 2008 hole hadn’t previously been assayed for fluorspar. It now shows 8% CaF2 over 47.2 metres, including 23.6% over five metres.

A 2019 hole reached 8.4% CaF2, 0.36% Nb2O5, 122 ppm Ta2O5 and 5.4% P2O5 over 22.5 metres, including 11.9% CaF2 over six metres. This interval extends at depth a 2010 hole that assayed 14.8% CaF2 over 6.2 metres. These results suggest continuation northwest along strike.

Another 2019 hole now shows 8.5% CaF2 over six metres.

True widths were unavailable.

Saville plans a 3D model of the trend to locate targets where high-grade fluorspar-bearing carbonatite might overlap with high-grade niobium-bearing carbonatite.

Fluorspar, niobium, tantalum and rare earths all appear on the U.S. list of 35 critical minerals. Along with phosphate rock, they also make the recently released EU list of 30 critical raw materials. In June Canada and the U.S. reaffirmed their commitment to the Joint Action Plan on Critical Minerals Collaboration announced in January, which would encourage investment and development for North American mining projects and supply chains.

As part of the EU plan to secure critical materials, this week the European Commission stated that “pilot partnerships with Canada, interested countries in Africa and the EU’s neighbourhood will start as of 2021.”

Arctic Star Exploration TSXV:ADD

Promising geology and proven methodology will come together at Arctic Star Exploration’s (TSXV:ADD) Diagras project in the Northwest Territories’ diamondiferous Lac de Gras region. Currently holding 40% of a joint venture, the company intends to assume operation and increase its ownership when spring offers optimum work conditions.

In addition to drilling, Arctic Star’s plans include gravity and electromagnetic surveys on seven of the property’s 21 known kimberlites. The gravity/EM approach follows that of Kennady Diamonds, which successfully employed the methodology on its Kennady North project two kilometres away. In 2018 Kennady North was acquired by Mountain Province Diamonds TSX:MPVD, De Beers’ JV partner on the adjacent Gahcho Kué mine. Gravity and EM have so far found five drill targets at Diagras.

Arctic Star’s 100%-held Timantti diamond project in Finland hosts nine known diamondiferous kimberlites. With some 150 kilograms of samples ready for processing, ground work is expected to resume once pandemic conditions allow.

Ares Strategic Mining TSXV:ARS

Eight companies offer eight opportunities at one online event

Once re-opened, Lost Sheep will be
America’s only producing fluorspar mine.

The U.S. currently imports its entire supply of this critical mineral but Ares Strategic Mining TSXV:ARS plans to change that soon by opening the country’s only fluorspar operation. Production at Utah’s Lost Sheep mine could begin this autumn without de-risking through successive PEA and feasibility studies, but with the apparent confidence of the Mujim Group. The multinational fluorspar mining and distribution company visited the property earlier this year prior to buying a 9% stake in Ares.

Three of five exploration holes found visible fluorspar, while assays have just been released from 12 holes totalling 900 metres of delineation drilling. Results show high grades over wide intervals from near-surface and at-surface intercepts. Metallurgical tests have upgraded Lost Sheep material above 97% CaF2, achieving the level of higher-priced acidspar.

Ares also holds the Liard fluorspar project in northern British Columbia. Seven areas of the highway-accessible 476-hectare property host historic, non-43-101 estimates.

Commerce Resources TSXV:CCE

Eight companies offer eight opportunities at one online event

Well-understood host minerals, distribution of magnet
feed elements and a friendly jurisdiction distinguish
Commerce Resources’ RE-fluorspar project.

Few if any elements dominate concern about critical minerals like rare earths. That places all the more focus on Commerce Resources’ (TSXV:CCE) Ashram deposit, an advanced-stage Quebec project that also hosts one of the world’s largest fluorspar resources. While working towards pre-feasibility, the company has metallurgical studies advancing on a number of levels, benefiting not only Ashram but the creation of supply chains independent of China. The deposit’s carbonatite-hosted mineralization and relatively simple monazite, bastnasite and xenotime mineralogy complement conventional rare earths processing. Metallurgy has also upgraded Ashram’s fluorspar content to higher-priced acidspar.

Ashram also features a strong presence of high-demand magnet feed elements neodymium, praseodymium, dysprosium and terbium. Work is underway to upgrade the 2012 resource that used a 1.25% cutoff to show:

  • measured and indicated: 29.27 million tonnes averaging 1.9% total rare earth oxides and 2.94% fluorine

  • inferred: 219.8 million tonnes averaging 1.88% TREO and 2.21% F

The deposit starts at surface.

Looking at other critical minerals, Commerce also holds the advanced-stage Blue River tantalum-niobium deposit in southern British Columbia.

Core Assets Corp CSE:CC

Eight companies offer eight opportunities at one online event

Historic results, more recent sampling and a
greater understanding of regional geology prompted
Core Assets’ major land expansion in B.C.

Determined to become a major explorer in northwestern British Columbia’s Golden Triangle, Core Assets Corp CSE:CC started trading in July, then began September with a nine-fold property expansion. The inspiration for boosting its Blue and Silver Lime holdings to 14,815 hectares comes from continual advancements in the understanding of porphyry, skarn and carbonate replacement-type deposits globally and in the Triangle itself.

The new ground covers the Llewelyn fault zone, which the company believes to be the main transport corridor for high-grade metals found on the property at surface. An historic, non-43-101 drill hole at Blue reached 0.27% copper over 173.2 metres. Grab samples from 2018 graded up to 1.57 g/t gold, 46.5 g/t silver and 8.46% copper.

The 2018 grab samples from never-drilled Silver Lime included 1.16 g/t gold, 913 g/t silver, 12.45% zinc and 20% lead. Core’s regionally experienced team plans a regional magnetic survey over the property.

Emerita Resources TSXV:EMO

Eight companies offer eight opportunities at one online event

Despite extensive previous mining, Aznalcollar
hosts an impressive historic base metals estimate.

Most of Spain’s bullion came from the New World but Emerita Resources TSXV:EMO believes there’s untapped gold-silver potential on its Paymogo polymetallic project. Located amid former and current operations in southern Spain’s Iberian Pyrite Belt, Paymogo’s Romanera deposit hosts an historic, non-43-101 estimate of 34 million tonnes averaging 0.42% copper, 2.2% lead, 2.3% zinc, 44.4 g/t silver and 0.8 g/t gold.

Eight kilometres away, Paymogo’s Infanta area has historic, non-43-101 reports of high-grade copper-lead-zinc-silver intervals. While preparing an exploration permit application, Emerita is compiling data from 51 holes at Romanera and 48 at Infanta for a digital database to guide another round of drilling.

The company also awaits a court decision regarding a disputed tender for the Aznalcollar zinc-lead past-producer on the same Iberian belt. In May Emerita signed a binding letter agreement to earn a 55% interest in the Sierra Alta gold property in northern Spain. Company assets also include a 50% JV interest in the Plaza Norte zinc project near Spain’s northern coast.

Saville Resources TSXV:SRE

Eight companies offer eight opportunities at one online event

Saville outperformed historic intercepts with its
Phase I drill program on the Niobium Claim Group in Quebec.

Two kilometres from Commerce Resources’ Ashram RE-fluorspar deposit, another company explores for other critical minerals—niobium and tantalum. Working on a 75% earn-in from Commerce, Saville Resources TSXV:SRE has also found fluorspar potential on the early-stage Niobium Claim Group.

Saville sunk five holes last year in a promising Phase I campaign on the property’s Mallard prospect. Along with historic results, three drill programs total 14 holes and 3,537 metres on Mallard. Each program surpassed its predecessor for grades and widths while expanding three zones of mineralization that remain open in all directions. Encouraging historic drill results have also come from the project’s Northwest and Star Trench prospects. Yet to be drilled are other high-priority areas, especially Miranna where high-grade boulder samples have reached an exceptional 5.93% Nb2O5.

The property’s host rock predominates in pyrochlore-group minerals and/or ferrocolumbite, amenable to familiar processing methods as the world’s main source of niobium supply.

Zinc8 Energy Solutions CSE:ZAIR

Intermittent green electricity, grid backup and off-grid supply call for long-term electrical storage. Zinc8 Energy Solutions CSE:ZAIR has made inroads into New York by offering a low-cost, reliable approach.

The company’s system stores electricity in zinc particles, avoiding expensive battery minerals like lithium, vanadium and cobalt. When the storage system provides electricity, zinc particles combine with oxygen. When the system recharges, the zinc particles are regenerated and oxygen is returned.

Storage can be scaled from 20 kW to megawatts, making Zinc8’s system suitable for microgrids and utilities. The latter have already shown interest. 

In January the New York Power Authority, America’s largest public power organization, selected the Zinc8 system out of more than 60 contenders for a commercial or industrial demonstration facility. Two months later Digital Energy Corp chose Zinc8 to install a 100 kW/1.5 MWh storage system at a combined heat and power (CHP) plant in Brooklyn. Buoyed by New York interest, Zinc8 has since created a U.S. subsidiary.

Saville Resources, Commerce Resources announce fluorspar trend on Quebec niobium property

July 23rd, 2020

by Greg Klein | July 23, 2020

Further analysis of previous drilling shows further critical mineral potential for an early-stage project. Saville Resources TSXV:SRE has identified an encouraging fluorspar trend in the Mallard area of its Niobium Claim Group following review of assays showing niobium, tantalum and phosphate, as well as fluorspar.

Saville Resources, Commerce Resources announce fluorspar trend on Quebec niobium property

Saville operates the 1,223-hectare project on a 75% earn-in from Commerce Resources TSXV:CCE that calls for $5 million of spending within five years. Two kilometres away, Commerce moves its Ashram rare earths-fluorspar deposit towards pre-feasibility.

Saville’s review covered results from historic drilling as well as last year’s five-hole, 1,049-metre program. Overall, three drill campaigns have totalled 14 holes and 3,537 metres.

The study outlines a fluorspar trend within the primary niobium trend that’s “broader and more extensive than previously understood,” the company stated. Stretching laterally at least 600 metres, the fluorspar trend remains open to the northwest, southeast and down dip, “and is interpreted to continue to surface where it is obscured by a shallow veneer of overburden,” Saville added. “Fluorspar mineralization is readily observable to the naked eye as the fluorspar present is purple in colour and relatively abundant where grades are of interest.”

The company now plans to have assay pulps undergo laboratory fluorine analysis.

Fluorspar, niobium and tantalum have been designated critical minerals by the United States. A number of American initiatives to secure domestic and allied sources include the National Defense Authorization Act for Fiscal Year 2021 which recently passed the U.S. House of Representatives and now faces Senate debate. In June Canada and the U.S. reaffirmed their commitment to the Joint Action Plan on Critical Minerals Collaboration announced in January, which would encourage investment and development for North American mining projects and supply chains.

Update: Commerce Resources’ metallurgy upgrades Quebec fluorspar to acid-spar

March 9th, 2020

On March 9 Commerce Resources announced a collaboration with CanmetMINING to enhance beneficiation performance for the company’s Ashram rare earths deposit. Funded by Natural Resources Canada, the study takes place within CanmetMINING’s rare earths and chromite R&D program. Commerce and CanmetMINING will present a paper on Ashram at the 2020 Conference of Metallurgists (COM2020) in Toronto next August.

 

by Greg Klein | Updated February 28, 2020

With further progress on a strong potential byproduct, an advanced rare earths project could provide a second critical mineral from a Canadian source. Metallurgical tests on material from Commerce Resources’ (TSXV:CCE) Ashram deposit in northern Quebec have achieved 97.8% calcium fluoride, surpassing the 97% level typical of the more expensive acid-spar grade.

Conducted at the Colorado lab of Hazen Research, the tests show Ashram’s amenability to standard physical separation techniques to upgrade fluorspar from a head grade of about 7.5% CaF2 to over 97%, Commerce pointed out.

Ashram is primarily a rare earth deposit that is well-positioned to supply the permanent magnet industry over the long term. However, these fluorspar test results also demonstrate the potential for Ashram to be a significant contributor to the acid-spar market.—Chris Grove,
president of Commerce Resources

The lab’s next trials will focus on removing impurities well as further improving fluorspar recovery, Commerce added.

The achievement follows December reports of flotation tests conducted by l’Université Laval and last month’s announcement that Hazen had studied an alternative or complimentary approach at the front end of the project’s current flowsheet.

This approach “includes a coarser-grind followed by a fluorspar pre-float as an initial beneficiation step to isolate a sizable portion of the fluorspar prior to material entering the primary REE recovery flowsheet,” Commerce stated.

Fluorspar’s higher-priced acid-grade is converted to hydrofluoric acid for the chemical industry and aluminum production. Considerable demand potential also comes from increasing use of refrigerants and from the growing lithium-ion battery market, according to Roskill. Met-spar, grading below 97%, is used in steel and cement production.

Apart from upgrading fluorspar, the Colorado lab has worked on improving REE recovery and producing concentrate samples requested by potential customers.

High-grade, near-surface drill results released by Commerce in November further highlight Ashram’s dual potential for rare earths and fluorspar. A few examples:

  • 1.71% rare earth oxides and 7.2% calcium fluoride over 221.95 metres, starting at 2.69 metres in downhole depth
  • (including 2.18% REO and 11.5% CaF2 over 36.6 metres)

  • 1.68% REO and 8.4% CaF2 over 101.86 metres, starting at 1.59 metres
  • (including 2% REO and 9.6% CaF2 over 13.28 metres)

True widths were unavailable.

Amid heightened concern about critical minerals, rare earths have gained considerable attention for their importance to the economy, clean energy and defence, among other applications. Less prominent, however, has been fluorspar, which also comes under the U.S. list of 35 critical minerals. China controls well over 50% of production but has become a net importer due to increasing domestic demand and mine shutdowns caused by environmental concerns, according to Roskill.

Commerce Resources’ metallurgy upgrades Quebec fluorspar to acid-spar

Working on northern Quebec’s Eldor property,
Commerce and Saville offer the Western world
potential for critical minerals including
rare earths, fluorspar, niobium and tantalum.

In January, Canada and the U.S. signed a Joint Action Plan on Critical Minerals to develop deposits and supply chains.

Looking at yet more critical minerals on the Eldor property that hosts Ashram, earlier this month Commerce joined Saville Resources TSXV:SRE to announce a preliminary mineralogical analysis on material from the Niobium Claim Group. Saville operates that project, two kilometres from Ashram, under a 75% earn-in from Commerce.

Using core from last year’s drill program, a University of Windsor research project found three encouraging signs for the project, the companies reported.

The property’s dominant niobium minerals are pyrochlore and columbite, the main source minerals for niobium globally, a fact that suggests favourable processing.

The property’s niobium may have been mobilized, which could potentially enhance a project’s grade.

The mineralogy supports a model of a continuous niobium mineralized trend through the complex.

Commerce and Saville noted parallels between the project’s Mallard prospect and Magris Resources’ Niobec mine in Quebec. Both projects feature carbonatites, and Niobec’s mineralization is hosted by pyrochlore and columbite similar in grain size to that found in Mallard’s preliminary analysis. Additionally, both Mallard and Niobec show mineralization in moderate to steeply dipping elongate lenses.

Having assayed high-grade niobium and tantalum from 2019 drilling, Saville plans further exploration this year.

In November Commerce closed a private placement totalling $2.51 million.

Update: Saville Resources reports B.C. Greenwood sample results, vends project

March 3rd, 2020

by Greg Klein | March 2, 2020, updated March 3, 2020

Update: On March 3 Saville Resources announced the sale of its Bud property to Ximen Mining TSXV:XIM for 388,888 Ximen shares, subject to TSXV approval.

A company focused on critical minerals in Quebec has also kept busy in an historic southern British Columbia mining camp. On March 2 Saville Resources TSXV:SRE released grab sample assays from a 2019 field program at the Bud property in the Boundary district that includes the Republic, Belcher, Rossland and Greenwood camps of B.C. and Washington. Some highlights included:

  • 3.84 g/t gold, 105 ppm cobalt, 2,200 ppm copper and 824 ppm zinc

  • 1.52 g/t gold, 247 ppm cobalt, 4,070 ppm copper and 50 ppm zinc

  • 0.864 g/t gold, 476 ppm cobalt, 6,540 ppm copper and 127 ppm zinc
Saville Resources reports B.C. Greenwood sample results

Grab samples from the previous year reached up to 4.57 g/t gold, 27.7 g/t silver and 6.7% copper; as well as 4.44 g/t gold, 17 g/t silver and 6.84% copper.

Saville stated the 381-hectare property potentially hosts copper-gold skarn mineralization similar to the Motherlode and Sunset properties 500 metres away that had historic production of 4.2 million tonnes averaging 0.8% copper and 1.3 g/t gold. The company also sees potential for gold-bearing epithermal veins.

Reporting on its flagship Niobium Claim Group in northern Quebec last month, Saville announced completion of a preliminary mineralogical analysis conducted as part of a University of Windsor research project. Among the results, the study found three encouraging signs for the project:

The dominant niobium minerals are pyrochlore and columbite, a potential processing advantage with the most common minerals for niobium globally.

The niobium may have been mobilized, which might enhance a project’s grade.

The mineralogy supports a model of a continuous niobium-mineralized trend through the complex.

Saville drew parallels between the project’s Mallard prospect and Magris Resources’ Niobec mine in Quebec. Both feature carbonatites, while Niobec’s mineralization is hosted by pyrochlore and columbite similar in grain size to that found in Mallard’s preliminary analysis. Additionally, both Mallard and Niobec show mineralization in moderate to steeply dipping elongate lenses.

Following near-surface, high-grade niobium and tantalum intercepts from last year’s drilling, Saville plans further exploration this year. The company also plans to evaluate the property’s fluorspar potential after reviewing impressive historic grades for calcium fluoride.

Niobium, tantalum and fluorspar appear on the United States list of 35 critical minerals. Amid increasing concern, in January the U.S. and Canada signed a Joint Action Plan on Critical Minerals to develop deposits and supply chains.

Saville operates the Niobium Claim Group under a 75% earn-in from Commerce Resources TSXV:CCE, which holds the advanced-stage Ashram rare earths deposit two kilometres away.

Commerce Resources sees further encouragement from Quebec rare earths lab tests

December 17th, 2019

by Greg Klein | December 17, 2019, updated January 7, 2020

Update: An academic paper on the flowsheet for Commerce Resources’ Ashram rare earths and fluorspar deposit will be presented at the Canadian Mineral Processors conference in Ottawa on January 23. Lead author Jean-François Boulanger, an assistant professor at l’Université du Québec en Abitibi-Témiscamingue in Rouyn-Noranda and manager of the Ashram metallurgical tests completed at l’Université Laval from 2018 to 2019, will discuss his study entitled Challenges of Scale-Up in Grinding and Flotation of Rare Earth Minerals. The report will also be published in the organization’s periodical CMP Proceedings.

“The Ashram deposit, with its simple rare earth and gangue mineralogy, and resultant well-understood processing techniques, potentially presents a base case scenario for some issues and, therefore, the test data generated by Laval has been used to formulate cautionary guidance for scale-up and large-scale concentrate production, potentially applicable to all rare earth projects regardless of mineralogy,” stated an announcement from Commerce.

Second and third authors of the study are Claude Bazin, professor and project supervisor at Laval, and Darren Smith, project manager at Ashram.

 

Another advance in rare earths processing helps distinguish this Canadian project as the United States and other allies express heightened concern about critical elements. Commerce Resources TSXV:CCE announced a potentially significant advance in flotation tests conducted by l’Université Laval on material from the company’s Ashram rare earths and fluorspar project in northern Quebec. Should further tests support this initial finding, the result could indicate a marked improvement in overall flotation performance.

Commerce Resources sees further encouragement from Quebec rare earths lab tests

Using a combined rougher concentrate from previous lab work, Laval undertook a cleaner-stage test producing a flotation concentrate of 21% rare earth oxides at a stage recovery of 92% and a stage mass pull of 41%, Commerce reported. “The current base case flowsheet incorporates a two-stage rougher only, resulting in a favourable flotation concentrate, typically of 7% to 10% REO at over 80% recovery and less than 30% mass pull.

“Subsequent cleaner stages have generally resulted in a significant drop in recovery. However, the cleaner test result from Laval indicates a potentially significant development in this regard, having resulted in a marked improvement in recovery and grade in the cleaner-stage flotation.”

Improved flotation would affect the stage where most rare earth elements are lost and also determine the amount of hydrochloric acid required, as well as other aspects of the flowsheet.

“In other words, the flotation performance has one of the largest impacts on the OPEX and CAPEX of the overall project flowsheet as it affects everything downstream of it,” the company stated. “Therefore continued improvement in the performance of the flowsheet’s flotation stage is a key interest.”

While Commerce explores funding opportunities to continue work at Laval, the company looks forward to announcing further metallurgical progress from ongoing studies by Hazen Research. The Colorado lab’s current work focuses on upgrading Ashram’s fluorspar to higher-priced acid grade, improving REE recovery and producing concentrate samples requested by potential customers.

Late last month Commerce released assays that included one of Ashram’s best intercepts, 2.38% REO over 64.54 metres, with sub-intervals including 3.02% over 28.35 metres. The near-surface results included impressive fluorspar grades, such as 7.2% calcium fluoride over 221.95 metres, including 11.5% CaF2 over 36.16 metres. Although this critical mineral wasn’t included in the project’s 2012 resource estimate, fluorspar will take its place in a resource update anticipated for the coming year.

In another critical minerals project two kilometres from Ashram, Saville Resources TSXV:SRE operates the Niobium Claim Group under a 75% earn-in from Commerce. Last June Saville released encouraging niobium-tantalum-phosphate drill results and is now analyzing the project’s historic, non-43-101 high-grade fluorspar assays.

Last month Commerce closed the final tranche of a private placement totalling $2.51 million. That followed a $413,749 private placement in August.

Commerce Resources congratulates Quebec PhD student for research on company’s rare earths project

December 5th, 2019

by Greg Klein | December 5, 2019

A study related to the Ashram rare earths-fluorspar deposit brought Université du Québec PhD candidate Sophie Costis first prize in an academic competition. Commerce Resources TSXV:CCE congratulated her on winning the $2,000 scholarship for her study on flotation tailings using the flowsheet for the company’s deposit. Costis delivered her presentation entitled Impact du gel-dégel et de la salinité sur le comportement de résidus miniers de terres rares en milieu nordique to l’Association Québécoise des Sciences de la Terre. Her first-place finish in le défi de la recherche en géosciences (Geoscience Research Challenge) was announced at last month’s Quebec Mines + Energy conference in Quebec City.

“The company is thrilled to see Sophie recognized for her hard work on the project over the last few years,” said Commerce president Chris Grove. “We are committed to advancing the Ashram project in an environmentally responsible manner and Sophie’s work will help build this foundation through high-quality data-gathering and analysis in a very important field.”

Backed by a $300,000 grant, Costis works in partnership with le Centre Eau Terre Environnement of l’Institut national de la recherche scientifique of l’Université du Québec. Expected to conclude late next year, her project provides further insight on tailings management in the flotation process plant.

Her findings so far show no serious concerns with Ashram’s flotation tailings management, show the process has no acid-generating potential and also show strong indications that there is no metal-leaching potential, Commerce stated.

In early October, Cynthia Kierscht, the U.S. deputy assistant secretary of state for Western Hemisphere affairs, hosted Shawn Tupper, associate deputy minister of Natural Resources Canada, at the first critical minerals working group meeting in Washington.

The work complements Ashram’s pre-feasibility studies for Ashram, which coincide with heightened concerns about critical minerals like fluorspar and especially rare earths. This week Canadian Press reported Ottawa is examining the role Canada could play in supplying the United States and other allied countries with minerals considered necessary to the economy, technology and defence.

NRCanada has contracted Roskill Consulting to forecast future demand for critical minerals that Canada could supply, CP added.

Last week Commerce released assays from near-surface intervals at Ashram showing high grades over wide widths. The company also has metallurgical studies underway at a Colorado lab to upgrade the project’s fluorspar potential, increase rare earths extraction and produce samples requested by potential customers.

Fluorspar wasn’t considered in the project’s 2012 resource but will be included in an update anticipated for the coming year, as will two seasons of extensive drilling. A major advantage of Ashram is the carbonatite-hosted deposit’s relatively simple monazite, bastnasite and xenotime mineralogy that’s familiar to conventional rare earths processing.

Fluorspar potential also comes under consideration at another critical minerals project two kilometres away, where Saville Resources TSXV:SRE operates the Niobium Claim Group under a 75% earn-in from Commerce. Following a drill program earlier this year, Saville released promising niobium-tantalum-phosphate results in June.

Last month Commerce closed the final tranche of a private placement totalling $2.51 million. A private placement in August brought in $413,749.

 

Update: An academic paper on Ashram’s flowsheet will be presented at the Canadian Mineral Processors conference in Ottawa on January 23. Lead author Jean-François Boulanger, an assistant professor at l’Université du Québec en Abitibi-Témiscamingue in Rouyn-Noranda and manager of the Ashram metallurgical tests completed at l’Université Laval from 2018 to 2019, will discuss his study entitled Challenges of Scale-Up in Grinding and Flotation of Rare Earth Minerals. The report will also be published in the organization’s periodical CMP Proceedings.

“The Ashram deposit, with its simple rare earth and gangue mineralogy, and resultant well-understood processing techniques, potentially presents a base case scenario for some issues and, therefore, the test data generated by Laval has been used to formulate cautionary guidance for scale-up and large-scale concentrate production, potentially applicable to all rare earth projects regardless of mineralogy,” stated an announcement from Commerce.

Second and third authors of the study are Claude Bazin, professor and project supervisor at Laval, and Darren Smith, project manager at Ashram.

Commerce Resources reports high grades over wide intervals at Quebec rare earths-fluorspar project

November 28th, 2019

With core moved from the storage vault to the lab, new assays further confidence in a resource update anticipated for next year as the Ashram deposit advances towards pre-feasibility. The results come from a 14-hole, 2,014-metre program sunk in 2016 but only recently assayed for budgetary reasons. Now cashed-up Commerce Resources TSXV:CCE unveils an impressive batch of near-surface rare earths and fluorspar intercepts from the northern Quebec property.

Commerce Resources reports high grades over wide intervals at Quebec rare earths-fluorspar project

Among the highlights are one of the project’s best-yet intercepts: 2.38% rare earth oxides over 64.54 metres, with sub-intervals including 3.02% over 28.35 metres. Another standout shows 1.71% over 221.95 metres, including 2.18% over 36.16 metres. Yet another hole boasts 2.16% over 53.55 metres. (True widths were unavailable.)

These are near-surface results, starting at downhole depths of 66.5 metres, 2.69 metres and 1.54 metres respectively.

Another critical mineral and one not factored into Ashram’s previous PEA, fluorspar also comes through in impressive grades, such as 7.2% calcium fluoride over 221.95 metres, including 11.5% CaF2 over 36.16 metres. Metallurgical studies currently underway work on upgrading the fluorspar to higher-priced acid grade in a flowsheet that would provide both rare earths and fluorspar concentrates, improve RE extraction and reduce tailings. The Colorado lab will also produce samples to meet requests from potential customers.

This round of definition drilling targeted the deposit’s northern, western and southern margins with holes spaced 50 metres apart, and in some cases 25 metres apart. Additional drilling at 25-metre centres may take place.

Using a 1.25% cutoff, Ashram’s 2012 resource estimate showed:

  • 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

The carbonatite-hosted deposit features relatively simple monazite, bastnasite and xenotime mineralogy, familiar to conventional rare earths processing

Anticipated for the coming year is Ashram’s first resource update since 2012, factoring in 9,625 metres of drilling since then. Previous drilling followed mineralization from near-surface to depths beyond 600 metres where mineralization remains open, as evidenced by 4.13% REO over 0.6 metres beginning at 599.9 metres’ depth.

Work continues as the United States and other allied countries show increasing concern about China’s domination of several critical minerals with a special focus on rare earths but also including fluorspar, tantalum and niobium. Commerce also holds the advanced-stage Blue River tantalum-niobium deposit in southern British Columbia.

About two kilometres from Ashram, Saville Resources TSXV:SRE operates the Niobium Claim Group under a 75% earn-in from Commerce. After releasing niobium-tantalum-phosphate results last June, Saville now has the project’s fluorspar potential under evaluation.

Earlier this month Commerce closed the final tranche of a private placement totalling $2.51 million. Another placement in August garnered $413,749.
