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.

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 group will continue talks in coming months to finalize the joint plan.—Canadian Press

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.

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

November 28th, 2019

by Greg Klein | November 28, 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.

Saville Resources to examine fluorspar potential of Quebec niobium-tantalum-phosphate project

November 26th, 2019

by Greg Klein | November 26, 2019

One long-term indication for fluorspar demand can be seen in China, which has become a net importer of the critical mineral despite being the world’s largest producer. Partly for that reason, Saville Resources TSXV:SRE now intends to evaluate that overlooked aspect of its Niobium Claim Group in northern Quebec.

Saville Resources to examine fluorspar potential of Quebec niobium-tantalum-phosphate project

Last spring the property underwent its first drill program in nine years, with results released in June for niobium, tantalum and phosphate. The core has yet to be assayed for fluorine. Yet drilling from 2008 and 2010 at the property’s Mallard prospect does show historic, non-43-101 grades as high as 31.6% calcium fluoride over 20.8 metres and 26.1% CaF2 over 32.4 metres.

Along with other promising intersections, the results suggest potential for a significant fluorspar zone, the company states. As a result, Saville says it “intends to further evaluate the fluorite potential at Mallard and incorporate such exploration initiatives within its overall exploration approach for niobium, which remains the focus.”

Saville operates the project under a 75% earn-in from Commerce Resources TSXV:CCE, which holds the Ashram rare earths deposit two kilometres away. Earlier this month Commerce announced lab tests to upgrade fluorspar from Ashram to higher-priced acidspar grade and study the extraction of additional rare earths from fluorspar concentrate. The work will be incorporated into Ashram’s pre-feasibility study and also produce samples to meet industry requests.

Fluorspar would add another critical mineral to both companies’ projects. Along with niobium, tantalum and rare earths, fluorspar made the list of 35 critical minerals compiled by the U.S. as that country pays heightened attention to their economic and strategic importance. According to the U.S. Geological Survey, China produced over 60% of world fluorspar supply last year.

Saville Resources plans Phase II drilling on Quebec niobium-tantalum-phosphate project

September 16th, 2019

by Greg Klein | September 16, 2019

A detailed analysis of last spring’s drill program along with other data has Saville Resources TSXV:SRE looking forward to a Q1 return engagement. Activity on the Niobium Claim Group in Quebec’s Labrador Trough occurs as the U.S. takes steps to secure reliable supplies of critical minerals including niobium and tantalum. The country relies on imports for its entire supply of both metals.

Near-surface assays previously released for this year’s five-hole, 1,049-metre campaign reached as high as 0.79% Nb2O5, 163 ppm Ta2O5 and 8.1% P2O5 over 37 metres, as well as 0.8% Nb2O5, 81 ppm Ta2O5 and 9% P2O5 over 31.5 metres. The latter intercept, the final hole of the season, featured a sub-interval showing 1.36% Nb2O5, 70 ppm Ta2O5 and 12.3% P2O5 over 4.5 metres.

Saville Resources plans Phase II drilling on Quebec niobium-tantalum-phosphate project

Saville’s drilling targeted the project’s Mallard prospect, where three programs so far have totalled 14 holes and 3,537 metres. Each campaign excelled its predecessor for grades and widths, expanding three known zones of mineralization which remain open in all directions, the company reported.

Predominating the host material are pyrochlore-group minerals and/or ferrocolumbite, familiar to the industry as the world’s main source of niobium production, Saville added.

“We appear to have only scratched the surface at Mallard and have yet to drill-test our other high-priority targets including Spoke and Miranna,” said president Mike Hodge.

Although work will focus on building an initial Mallard resource, Spoke and Miranna might also get rig attention to determine their potential for connecting with Mallard.

Saville operates the project under a 75% earn-in from Commerce Resources TSXV:CCE. On another critical minerals project two kilometres away, Commerce advances its Ashram rare earths deposit towards pre-feasibility.

Saville’s portfolio also includes the Bud project in southern British Columbia’s busy Greenwood camp. Grab sample assays released last April showed grades 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.

Commerce Resources’ rare earths metallurgy optimized by university lab

August 1st, 2019

by Greg Klein | August 1, 2019

Successful methods applied in separate laboratories further demonstrate the amenability of a Quebec rare earths deposit that’s progressing towards the pre-feasibility stage. Using material from Commerce Resources’ (TSXV:CCE) Ashram project in northern Quebec, l’Université Laval successfully used an alternative flowsheet approach to create a mixed REE concentrate. The tests add to the work of Hazen Research in Colorado and Merker Mineral Processing/UVR-FIA in Germany.

Commerce Resources’ rare earths metallurgy optimized by university lab

Commerce announced receipt of Laval’s final report on August 1. The university tested Ashram material on bench-scale levels of one kilogram and on larger batches of 10 to 30 kilograms. A total of about 1,500 kilograms went through Laval’s own flotation circuit and reagent scheme.

The large batches produced around 170 kilos of flotation concentrate grading 11.2% rare earth oxides, with a mass pull of 11.3% (percent of material reporting to concentrate), the company stated. Laval’s new reagent scheme offers Ashram potentially greater flotation performance, Commerce added.

“We are very happy with the results of our collaboration with Laval and look forward to continued work with local academic institutions to further develop REE expertise in the province of Quebec and, moreover, to move the Ashram deposit closer to production,” commented president Chris Grove.

The news comes amid heightened concern in the U.S. for critical minerals supply, especially rare earths.

Commerce holds interests in two other critical minerals projects. On the Niobium Claim Group, just a few kilometres from Ashram, Saville Resources TSXV:SRE drilled high-grade, near-surface niobium along with tantalum and phosphate last spring while working towards a 75% earn-in from Commerce. The latter company also holds the advanced-stage Blue River tantalum-niobium project in southern British Columbia.
