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.”

And here are the companies

 

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.

Update: Commerce Resources gets cash grants to further Canadian rare earths-fluorspar research

August 25th, 2020

by Greg Klein | August 24, 2020

An advanced-stage northern Quebec project continues to attract outside interest as a number of sources contribute metallurgical R&D funds. On August 25 Commerce Resources TSXV:CCE announced grants totalling $160,000 to help develop the company’s Ashram rare earths-fluorspar deposit. The funding follows a number of academic and government-backed research initiatives into the project. This money will back collaborative research by Commerce, l’Université du Québec en Abitibi-Témiscamingue (UQAT) and the Industrial Waste Technology Centre (CTRI).

“A principal focus of the joint research program involving experts from CTRI, UQAT, and Commerce Resources will be the optimization of the mineral liberation and flotation schemes, used to produce a high-grade rare earth mineral concentrate over 30% REO for hydrometallurgical processing,” said Jean-François Boulanger, professor of hydrometallurgy for the Rare Earth Elements Institute for Research in Mines and Environment. “After the initial lab-scale testing phase, pilot-scale operation will be conducted, increasing confidence when scaling-up the developed process.”

Commerce president Chris Grove added that the work will enhance Ashram’s project efficiency “as well as make a strong contribution to academia and the research and development of strategic minerals in Quebec.”

The news comes four days after the announcement that two research papers featuring Ashram will be presented to the 2020 Conference of Metallurgists on October 14 and 15.

by Greg Klein | August 20, 2020

The lingo might prove daunting to the uninitiated, yet technical studies like these help advance not only a specific project but the Canadian industry in general. Two papers referring to Commerce Resources’ (TSXV:CCE) Ashram rare earths-fluorspar deposit in northern Quebec will be presented at the upcoming 2020 Conference of Metallurgists (COM2020).

Organized by the Metallurgy and Materials Society of the Canadian Institute of Mining, Metallurgy and Petroleum, COM2020 was originally planned for Toronto this month. The rescheduled event takes place online October 14 and 15.

The first paper results from Ashram project manager Darren Smith’s collaboration with Tesfaye Negeri and Maziar Sauber of Natural Resources Canada’s CanmetMINING division. Entitled Mineral Processing Flowsheet Options for the Ashram Rare Earth and Fluorspar Deposit, the paper details test work that improved flotation through “a combination of distributed reagent additions, reagent synergism and reverse conditioning in a very simple and basic flotation circuit,” Commerce stated.

The findings are “directly applicable to the project’s working flowsheet,” the company added.

The second paper comes from Kang Sun, Christel Bemelmans and Nick Hazen of Hazen Research, operators of Ashram’s primary metallurgical lab in Colorado. Entitled Recovering Rare Earths and Other Metallic Values from Fluorine-Containing Concentrates using Carbochlorination and Aqueous Leaching, it discusses Ashram concentrate as one of two feedstocks tested with a thermal process to produce rare earth chloride that’s soluble in dilute hydrochloride.

Commerce expressed its pleasure to provide “continued support to the academic and institutional rare earth element research and development industry through the supply of Ashram deposit material and geological support. The deposit outcrops at surface and has allowed for cost-effective collection of large amounts of material for test work. As such, the company is actively engaged with various research and academic institutions to support the advancement of the REE industry in Canada, and in Quebec specifically.”

Other Ashram research has included a tailings management study by le Centre Eau Terre Environnement of l’Institut national de la recherche scientifique of l’Université du Québec that was published last May in the international peer-reviewed journal Science of the Total Environment.

The studies have taken place while Commerce advances Ashram to the pre-feasibility level. Rare earths and fluorspar rank among 35 minerals declared critical by the U.S.

In June the company closed an over-subscribed private placement of $1.2 million. Previous placements closed on $300,000 in May and $2.51 million in November.

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.

Commerce Resources further tests acid-grade fluorspar potential of Quebec rare earths project

June 11th, 2020

by Greg Klein | June 11, 2020

Another round of metallurgical studies endeavours to add a critical mineral byproduct to a critical mineral project. Commerce Resources (TSXV:CCE) has re-engaged Hazen Research’s Colorado lab for Phase II studies on the fluorspar component of its Ashram rare earths deposit. Phase I results reported in February have already produced calcium fluoride grading 97.8%, exceeding the 97% level of fluorspar’s more expensive acid-grade.

Phase II will focus on removing impurities, taking advantage of a flowsheet that doesn’t require a complicated secondary circuit for fluorspar. Using conventional methods, coarser and looser fluorspar grains will be recovered prior to entering the initial rare earths circuit. Most of the remaining fluorspar will be recovered as a tailings stream.

Commerce Resources further tests acid-grade fluorspar potential of Quebec rare earths project

Although not considered in Ashram’s PEA report, fluorspar offers considerable economic potential as the project moves towards pre-feasibility.

Previous lab work has demonstrated the ability to produce over 45% rare earths oxides with an impressive 75% recovery rate. In addition to tests by Hazen Research, studies on Ashram material have been conducted at academic and research institutions including McGill University, l’Université du Québec, l’Université Laval, the University of Windsor and the CanmetMINING division of Natural Resources Canada. Earlier this month Ashram came to global attention through an article by PhD candidate Sophie Costis and her team in the international peer-reviewed journal Science of the Total Environment.

Apart from hosting a domestic supply of critical minerals, Ashram’s advantages include carbonatite host rocks with relatively simple monazite, bastnasite and xenotime mineralogy amenable to conventional rare earths processing. The near-surface and at-surface deposit features a strong presence of sought-after magnet feed elements.

Ashram’s resource uses a base case 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

Following extensive drilling, Commerce now has geological modelling underway for a resource update.

Commerce Resources’ Quebec rare earths project gets international academic attention

June 1st, 2020

by Greg Klein | June 1, 2020

Not a subject that normally excites investors, tailings management is nevertheless an important consideration for advanced-stage projects. A previously announced academic article on Commerce Resources’ (TSXV:CCE) Ashram rare earths deposit now comes to an international audience.

Commerce Resources’ Quebec rare earths project gets international academic attention

Written and researched by a six-person team led by PhD candidate Sophie Costis, Assessment of the Leaching Potential of Flotation Tailings from Rare Earth Mineral Extraction in Cold Climates was published last month in Science of the Total Environment, an international peer-reviewed journal.

The study results from tailings characterization test programs still underway by le Centre Eau Terre Environnement of l’Institut national de la recherche scientifique (INRS).

Funding comes from a $300,000 grant provided jointly by le Fonds de recherche du Québec—Nature et technologies and le Ministère de l’Énergie et des Ressources naturelles. Although the program was scheduled to finish next December, Commerce and INRS hope to extend the project through the same funding sources.

An earlier presentation on her Ashram research won Costis first prize in the Geoscience Research Challenge held by l’Association Québécoise des Sciences de la Terre. Her award was announced in November at the Quebec Mines + Energy conference in Quebec City.

“We continue to be impressed by the quality of work being completed by Sophie Costis and the team at the INRS, and are very happy to have been able to be involved and contribute to REE research in Quebec, and now globally,” said Commerce president Chris Grove.

The company’s work continues on the northern Quebec Ashram rare earths-fluorspar project, which hosts two of the 35 minerals considered critical by the U.S. Rare earths have been an increasing cause of concern to the American government, which relies heavily on China for these elements essential to defence, medicine and clean energy technology, among other applications.

Apart from a friendly jurisdiction, Ashram benefits from carbonatite host rocks with relatively simple monazite, bastnasite and xenotime mineralogy that’s familiar to conventional rare earths processing.

Commerce Resources announces tailings management progress for Canadian rare earths deposit

The laboratory set-up for
kinetic testing by le Centre
Eau Terre Environnement.

One day after reporting on the Ashram rare earths flowsheet studies conducted by Natural Resources Canada’s CanmetMINING division, Commerce Resources TSXV:CCE announced findings from tailings management studies for the Quebec deposit. Undertaken by le Centre Eau Terre Environnement of l’Institut national de la recherche scientifique, the tests found the flotation tailings are “relatively benign with no major issues identified with the material or its management,” Commerce stated.

The study found “tailings are not acid-generating due to the material’s high carbonate and low sulphide content resulting in a natural neutralization effect,” an advantage that also cuts costs.

Additionally, the tailings aren’t considered hazardous or radioactive according to Quebec’s Hazardous Materials Regulations and Environmental Quality Act.

“Concentrations of all elements in the tailings’ leachate fall below the ‘high-risk’ criteria as outlined in Directive 019,” Commerce pointed out.

Further test work is required on freeze-thaw cycles, which “appear to play an important role in mineral solubility.”

Kinetic tests continue to provide data “for better understanding of how the tailings may be altered over time and for proper mitigation measures to be implemented if any elements are indicated to be potentially problematic to the environment.”

The next steps will include creating a model of tailings weathering.

The project was expected to conclude in December but Commerce and the INRS are considering an extension under similar funding. The studies have been backed by a $300,000 grant provided jointly by le Fonds de recherche du Québec—Nature et technologies and le Ministère de l’Énergie et des Ressources naturelles.

Commerce Resources’ NRCan collaboration moves forward on rare earths metallurgy

May 13th, 2020

by Greg Klein | May 13, 2020

A co-operation with Natural Resources Canada brings significant progress to an advanced-stage northern Quebec critical minerals deposit. Commerce Resources TSXV:CCE announced the findings from NRCan’s CanmetMINING division, which has been working on the flotation circuit for material from the company’s Ashram rare earths and fluorspar project in northern Quebec.

Commerce Resources NRCan collaboration moves forward on rare earths metallurgy

As the U.S. shows increasing interest in Canadian
critical mineral deposits, a poll finds widespread
Canadian support for their development and export.

CanmetMINING “has completed collector screening, an evaluation of mixed collectors, reverse conditioning tests, cleaning stage tests and a continuous process simulation with a locked cycle test,” Commerce stated.

The work has identified “an alternative reagent scheme and flotation circuit to achieve, and potentially exceed, the target objective of less than 25% mass pull at more than 80% recovery. This has also been achieved using one-half to one-quarter of the quantity of reagents utilized in prior test work completed by other metallurgical labs. Previous work has identified reagents as a key area of optimization in the Ashram deposit’s flotation circuit and where significant cost advantages may be found by screening the performance of each pertinent reagent with respect to its consumption and purchase cost.”

Improved flotation performance “has been achieved through a combination of distributed reagent additions, reagent synergism and reverse conditioning in a very simple and basic flotation circuit,” the company added.

The findings precede a detailed report, Mineral Processing Flowsheet Approaches for the Ashram Rare Earth and Fluorspar Deposit, that CanmetMINING will present to the 2020 Conference of Metallurgists in Toronto next August.

Some aspects of CanmetMINING’s upcoming work will involve Corem, which claims Canada’s largest concentration of R&D resources for mineral processing. Partnering with the governments of Quebec and Canada, Corem works with its 15 mining company members and its international clients to provide specialized services and research expertise. Corem’s tests on a 400-kilogram delivery of Ashram material is expected to resume as COVID-19 restrictions ease.

Funding comes from NRCan through CanmetMINING’s rare earth element and chromite R&D program to develop new extraction technologies, address Canadian regulations and learn more about Canadian deposits.

Metallurgical studies elsewhere have also advanced Commerce’s Ashram project. In February the company announced that Hazen Research’s Colorado pilot plant had produced a calcium fluoride concentrate grading 97.8%, surpassing the 97% level typical of fluorspar’s more expensive acid-spar grade.

The previous December Commerce released promising results from Université Laval metallurgical studies on Ashram material.

Both fluorspar and rare earths figure in the American list of 35 critical minerals. In January Canada and the U.S. announced their Joint Action Plan on Critical Minerals Collaboration, encouraging the use of Canadian resources to reduce American dependency on rival countries.

Commerce’s May 13 announcement coincides with poll results showing widespread support for critical minerals development in Canada. Released by the Mining Association of Canada, the survey found:

  • 88% of respondents want Canada to increase its role in producing critical minerals for world markets

  • 86% want to encourage international investment into Canadian critical minerals and metals companies that are sustainability leaders

  • 83% want to encourage Canadian production of critical minerals to compete with China

  • 81% want to promote interest in Canadian critical minerals by drawing attention to Canada’s high standards of sustainability

Commerce’s Ashram deposit features carbonatite-hosted mineralization and relatively simple monazite, bastnasite and xenotime mineralogy that’s favourable to conventional rare earths processing.

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

  • 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 near-surface deposit also shows a strong distribution of the high-demand magnet feed elements neodymium, praseodymium, dysprosium and terbium.

Earlier this week Commerce offered a private placement up to $1 million. The company closed private placements of $300,000 this month and $2.51 million in November.
