Gaia Metals applies new geophysical analysis to Quebec polymetallic project

December 11th, 2019

by Greg Klein | December 11, 2019

This type of geophysical survey hasn’t changed much in two decades, but the technology of evaluation has. With that in mind, Gaia Metals TSXV:GMC (formerly 92 Resources) plans an up-to-date re-analysis of existing IP-resistivity data from its Corvette-FCI property. The process should offer a cost-effective method of gaining new insight into the project.

Gaia Metals applies new geophysical analysis to Quebec polymetallic project

Gaia Metals’ Corvette-FCI project has already shown
impressive sample results for gold, copper and lithium.

The James Bay-region property has so far yielded high-grade samples of gold, copper-gold-silver and lithium-tantalum. Now the company plans to apply new technology to data collected up to 2000.

IP-resistivity surveys have proven “well-suited to detect near-surface disseminated sulphide mineralization (IP anomalies), as well as areas of alteration and/or silicification (resistivity anomalies),” Gaia stated. “This geophysical tool is commonly used in greenstone-hosted gold and base metal exploration and is often effective at qualifying drill targets initially developed from surface mapping and sampling. With the mineralization styles identified at Corvette-FCI, coupled with the thin overburden cover in the area, IP-resistivity offers an efficient sub-surface scan at good resolution and reasonable cost.”

The original survey covered two grids: Golden Gap (now known as FCI West) and Island Lake (FCI East), which includes the Lac Bruno boulder field. IP targets from the original evaluation have yet to be drilled, “further highlighting the value in modern re-processing to prioritize the targets,” Gaia added.

The company expects to conduct new surveying along the property’s Maven trend, extending east across the Lac Smokycat-SO, Lorraine and Elsass showings, where historic sampling brought impressive copper-gold-silver grades. Expected for completion next spring, the survey will precede ground mapping and sampling scheduled for June and July.

Emphasizing the project’s polymetallic promise were surface samples released in September from last summer’s field program. Lithium grades from six newly found pegmatites reached up to 4.72% Li2O, while tantalum numbers included 564 ppm Ta2O5. Gold samples included a Lac Bruno boulder assay as high as 11.9 g/t. A Lorraine outcrop featured 8.15% copper, 1.33 g/t gold and 171 g/t silver.

The project consists of Gaia’s 100%-held Corvette claims and a 75% earn-in from Osisko Mining TSX:OSK spinout O3 Mining TSXV:OIII on the FCI-East and FCI-West blocks.

Among other assets, Gaia’s portfolio includes the Pontax lithium-gold property in Quebec, the Golden silica property in British Columbia and a 40% stake in the Northwest Territories’ Hidden Lake lithium property.

Last week the company closed a private placement of $412,199.

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.

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.

Visual Capitalist looks at the top 10 strongest metals

 

The use of metals and the advancement of human civilization have gone hand in hand—and throughout the ages, each metal has proved its worth based on its properties and applications.

This visualization from Viking Steel Structures outlines the 10 strongest metals on Earth and their applications.

What are metals?

Metals are solid materials that are typically hard, shiny, malleable and ductile, with good electrical and thermal conductivity. But not all metal is equal, which makes their uses as varied as their individual properties and benefits.

The periodic table below presents a simple view of the relationship between metals, nonmetals and metalloids, which you can easily identify by colour.

Visual Capitalist looks at the top 10 strongest metals

 

While 91 of the 118 elements of the periodic table are considered to be metals, only a few of them stand out as the strongest.

What makes a metal strong?

The strength of a metal depends on four properties:

  • Tensile strength: How well a metal resists being pulled apart

  • Compressive strength: How well a material resists being squashed together

  • Yield strength: How well a rod or beam of a particular metal resists bending and permanent damage

  • Impact strength: The ability to resist shattering upon impact with another object or surface

Here are the top 10 metals based on these properties.

 

Rank Type of metal Example use Atomic weight Melting point
#1 Tungsten Making bullets and missiles 183.84 u 3422°C / 6192 °F
#2 Steel Construction of railroads, roads, other infrastructure and appliances n/a 1371°C / 2500°F
#3 Chromium Manufacturing stainless steel 51.96 u 1907°C / 3465°F,
#4 Titanium In the aerospace industry, as a lightweight material with strength 47.87 u 1668°C / 3032°F
#5 Iron Used to make bridges, electricity, pylons, bicycle chains, cutting tools and rifle barrels 55.85 u 1536°C / 2800°F
#6 Vanadium 80% of vanadium is alloyed with iron to make steel shock- and corrosion-resistant 50.942 u 1910°C / 3470°F
#7 Lutetium Used as catalysts in petroleum production 174.96 u 1663 °C / 3025°F
#8 Zirconium Used in nuclear power stations 91.22 u 1850°C / 3.362°F
#9 Osmium Added to platinum or indium to make them harder 190.2 u 3000°C / 5,400°F
#10 Tantalum Used as an alloy due to its high melting point and anti-corrosion 180.94 u 3,017°C / 5462°F

 

Out of the forge and into tech: Metals for the future

While these metals help to forge the modern world, there is a new class of metals that are set to create a new future.

Rare earth elements (REEs) are a group of metals that do not rely on their strength, but instead their importance in applications in new technologies, including those used for green energy.

 

Metal Uses
Neodymium Magnets containing neodymium are used in green technologies such as the manufacture of wind turbines and hybrid cars
Lanthanum Used in catalytic converters in cars, enabling them to run at high temperatures
Cerium This element is used in camera and telescope lenses
Praseodymium Used to create strong metals for use in aircraft engines
Gadolinium Used in X-ray and MRI scanning systems, and also in television screens
Yttrium, terbium, europium Making televisions and computer screens and other devices that have visual displays

 

If the world is going to move towards a more sustainable and efficient future, metals—both tough and smart—are going to be critical. Each one will serve a particular purpose to build the infrastructure and technology for the next generation.

Our ability to deploy technology with the right materials will test the world’s mettle to meet the challenges of tomorrow—so choose wisely.

92 Resources expands potential lithium trend in Quebec, hits 4.72% Li2O with tantalum

September 24th, 2019

by Greg Klein | September 24, 2019

Update: On October 17, 2019, 92 Resources began trading under a new name and stock symbol: Gaia Metals Corp TSXV:GMC.

New discoveries increase the lithium-tantalum potential of a copper-gold-silver project in the James Bay-region Corvette-FCI property. Following high-grade gold assays released last week and copper-gold-silver results the week before, 92 Resources TSXV:NTY announced lithium-tantalum samples on six newly found spodumene-bearing pegmatites from last summer’s field program. Grades reached as high as 4.72% Li2O, along with encouraging tantalum numbers.

The discoveries expand the prospective lithium trend to more than 25 kilometres. Among the results, eight samples from the CV5 and CV6 pegmatites averaged 3% Li2O and 154 ppm Ta2O5, peaking at 4.06% Li2O and 564 ppm Ta2O5.

CV7 featured an assay of 4.44% Li2O and 195 ppm Ta2O5.

CV8 showed another 4.44% Li2O, along with 205 ppm Ta2O5.

CV9 and CV10 produced multiple samples grading over 2% Li2O, reaching up to 4.72% Li2O.

CV11 hit a tantalum high point of 386 ppm Ta2O5, with 0.66% Li2O.

“This lithium exploration trend is interpreted to reside, with some overlap, between the northern gold exploration trend and the southern copper-gold-silver exploration trend (the Maven trend), potentially indicating a large zone of structural weakness within the greenstone belt which favours spodumene pegmatite emplacement,” the company stated.

The 23-day program also found mineralized boulders, some in a down-ice direction that could indicate a source in CV5 and CV6. But other boulders suggest a different origin and the possibility of more spodumene-bearing pegmatites to be discovered. One of the latter group of samples graded 2.72% Li2O.

“Although the focus of the program was base and precious metals, we would be remiss if we did not also evaluate the same areas of the property for other commodities that may be valuable and of interest, now or in the near-term,” commented 92 president/CEO Adrian Lamoureux. Both lithium and tantalum have been declared critical minerals by the U.S. as the country shows increasing concern about reliable sources.

The project consists of 92’s 100%-held Corvette claims and a 75% earn-in from Osisko Mining TSX:OSK on the FCI-East and FCI-West blocks.

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.

92 Resources hits high-grade copper-gold-silver with new Quebec discoveries

September 10th, 2019

by Greg Klein | September 10, 2019

Update: On October 17, 2019, 92 Resources began trading under a new name and stock symbol: Gaia Metals Corp TSXV:GMC.

Sample assays from two new discoveries have this company “ecstatic” about its James Bay-region Corvette-FCI project. Coming at the end of last summer’s 23-day field program, the findings have 92 Resources TSXV:NTY obviously enthusiastic about the property’s New Lorraine and Elsass prospects.

92 Resources hits high-grade copper-gold-silver with new Quebec discoveries

The highlight of 92’s summer campaign, this New Lorraine
sample graded 8.15% copper, 1.33 g/t gold and 171 g/t silver.

Some highlights from a New Lorraine outcrop include:

  • 8.15% copper, 1.33 g/t gold and 171 g/t silver

  • 1.55% copper, 0.14 g/t gold and 20.9 g/t silver

  • 0.23% copper, 3.55 g/t gold and 37.7 g/t silver

Located about 2.3 kilometres east along trend, Elsass hosts three outcrops over an approximately 350-metre strike that’s about 60 metres wide. Some Elsass samples feature:

  • 3.63% copper, 0.64 g/t gold and 52.3 g/t silver

  • 2.68% copper, 0.2 g/t gold and 43.9 g/t silver

  • 1.86% copper, 1.12 g/t gold and 32.6 g/t silver

Both prospects form part of the larger Maven trend, formerly called the Southern trend, and sit on the property’s FCI West claim block. With similar rock types and mineralization, the company considers the area between the two prospects highly prospective.

characterizing Elsass outcrops.

Proclaiming himself “ecstatic” with the results, president/CEO Adrian Lamoureux said, “With over eight kilometres of under-explored prospective trend and no drilling completed to date, we have literally only scratched the surface of this trend’s potential.”

The four-person crew from Dahrouge Geological Consulting collected 680 rock samples, as well as 211 soil samples up-ice from the Lac Bruno prospect. About three-quarters of the program explored the project’s FCI-East and FCI-West blocks, under a 75% option from Osisko Mining TSX:OSK. The remainder of the work targeted 92’s 100%-held Corvette claims. 

The project sits within the Lac Guyer Greenstone Belt, part of the La Grande Greenstone Belt, about six to 18 kilometres south of the Trans-Taiga Road and adjacent powerline.

The Maven trend hosting New Lorraine and Elsass also includes new discoveries at the Black Forrest and Hund showings. A Black Forrest sample graded 1.13% copper, 0.05 g/t gold and 19.5 g/t silver. Hund featured 3.28% copper, 0.78 g/t gold and 30.1 g/t silver.

Historic work on Maven’s Lac Smokycat-SO, Golden Gap and Tyrone T-9 showings have also brought high grades, although in non-43-101 reports. Together, the prospects suggest a potential copper-gold-silver trend stretching more than eight kilometres, 92 stated.

Still to come are regional assays, along with lithium-tantalum results. Channel samples released last year from Corvette’s CV1 pegmatite graded up to 2.28% Li2O and 471 ppm Ta2O5 over six metres.

Other 92 properties in Quebec include Eastman, Lac du Beryl and Pontax. Grab samples from Pontax featured up to 0.94% Li2O and 520 ppm Ta2O5.

In British Columbia 92 holds the Golden frac sand project adjacent to Northern Silica’s Moberly silica mine, as well as the Silver Sands vanadium prospect. In the Northwest Territories the company has a 40% stake in the Hidden Lake lithium project, where all 10 holes of last year’s 1,079-metre drill program hit grades above 1% Li2O.

92 Resources finds new potential for gold, copper, lithium in northern Quebec

August 8th, 2019

by Greg Klein | August 8, 2019

With the conclusion of a productive summer field program, additional areas of interest open up at the James Bay-region Corvette-FCI property. A four-person, 23-day campaign discovered a new copper prospect, further explored a gold prospect and found several spodumene-bearing pegmatites, among other showings. Encouraging visual evidence has 92 Resources TSXV:NTY looking forward to assays.

About three-quarters of the program focused on the project’s FCI-East and FCI-West blocks, optioned under a 75% earn-in from Osisko Mining TSX:OSK. The rest targeted 92’s 100%-held Corvette claims. 

92 Resources finds new potential for gold, copper, lithium in northern Quebec

Chalcopyrite mineralization at the Elsass copper
prospect opens a new area of interest for 92 Resources.

Discovered late in the season, the Elsass copper prospect features chalcopyrite mineralization at surface over widths estimated from 40 to 60 metres along a strike of at least a kilometre. Pending lab results for surface samples, the crew could return this fall for further exploration.

The company also awaits assays from the property’s Lac Bruno gold prospect. Finding similar mineralogy up-ice from a boulder field where historic, non-43-101 samples graded between 1 g/t and 38 g/t gold, the crew collected soil samples on the 100%-held Corvette claims.

Apart from precious and base metals, Corvette-FCI shows potential for energy minerals. The summer program found the project’s largest known pegmatite so far. An outcrop about 220 metres long and 20 to 40 metres wide was located about a kilometre southwest along strike of the property’s CV1 and CV2 pegmatites. Lithium-tantalum channel samples released last year from CV1 reached up to 2.28% Li2O and 471 ppm Ta2O5 over six metres. Still to come are this summer’s assays.

The campaign also targeted the Golden Gap prospect at FCI West, where historic results include outcrop samples between 3.1 g/t and 108.9 g/t gold, a drill intercept of 10.5 g/t over seven metres, and a channel sample of 14.5 g/t over two metres.

The summer program also focused on the southern copper trend and other historic mineral showings, 92 reported.

Corvette-FCI sits within the Lac Guyer Greenstone Belt, part of the La Grande Greenstone Belt, about six to 18 kilometres south of the Trans-Taiga Road and powerline.

The company’s Quebec portfolio also includes the Eastman, Lac du Beryl and Pontax properties. Grab samples from the latter graded up to 0.94% Li2O and 520 ppm Ta2O5.

92’s diverse projects extend to British Columbia and the Northwest Territories. In B.C. the company holds the Silver Sands vanadium prospect and, adjacent to Northern Silica’s high-grade Moberly silica mine, the Golden frac sand project. 92 also has a 40% stake in the NWT’s Hidden Lake lithium project, where Far Resources CSE:FAT holds the remainder. All 10 holes of last year’s 1,079-metre drill campaign found grades above 1% Li2O, with one intercept showing 1.6% over 9.2 metres. A mini pilot plant produced 40 kilograms of concentrate grading 6.11% Li2O, with recovery surpassing 80%, from Hidden Lake material.

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.
