Commerce Resources closes season on Quebec quest for rare earths and rare metals

October 11th, 2017

by Greg Klein | October 11, 2017

With this year’s field program now complete, Commerce Resources TSXV:CCE reports progress on a Quebec property hosting both advanced and early-stage projects. The bulk of the work brings the Eldor property’s Ashram rare earths deposit closer to pre-feasibility. About one kilometre east of Ashram, meanwhile, the company has Eldor’s Miranna target under scrutiny for its niobium-tantalum-phosphate potential.

Commerce Resources closes season on Quebec quest for rare earths and rare metals

Core from a 14-hole, 2,014-metre infill
campaign now makes its way to the lab.

Renewing anticipation of Ashram assay results, the team sent 1,256 core samples from last year’s drilling to the lab. The 14-hole, 2,014-metre program focused on definition drilling of the carbonatite-based deposit featuring the minerals monazite, bastnasite and xenotime, all familiar to conventional REE processing. The deposit also features a strong distribution of the critical elements neodymium, europium, terbium, dysprosium and yttrium.

Using a 1.25% cutoff, Ashram’s 2012 resource 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

Nine composite core samples will be tested to determine rock geomechanical characteristics to aid design of the processing plant. “Initial comminution testing indicates that the Ashram material is relatively soft, which directly correlates to lower energy consumption during the crushing and grinding process, where often the bulk of a mining operation’s energy is consumed,” the company stated. Other work included downloading data from an on-site weather station, as well as from lake and downhole instruments.

As for early-stage work, the crew collected 36 samples that largely targeted the Miranna area. Observing significant niobium-tantalum mineralization on surface, the team identified overlapping mineralized boulder trains that appear to end in the same area, increasing Miranna’s potential, Commerce added. Samples taken last year graded as high as 5.9% niobium pentoxide, with impressive tantalum, phosphate and rare earths numbers as well.

In southern British Columbia the company also has tantalum-niobium at its Blue River deposit, which reached PEA in 2011. Commerce signed an MOU in July to test a one-tonne sample for a proprietary method of processing.

Another MOU would have Ucore Rare Metals TSXV:UCU test a selective separation process on Ashram material. Samples have already undergone favourable metallurgical tests at a Colorado facility.

Hoping to bring clean, cost-effective energy to northern Quebec, Commerce also has an MOU with TUGLIQ Energy to determine Eldor’s potential for wind-generated electricity.

Arctic Star Exploration finds “highly anomalous” niobium, rare earths and phosphate at B.C. project

September 25th, 2017

by Greg Klein | September 25, 2017

Highly anomalous means highly encouraging, especially at such an early stage of exploration. That’s how Arctic Star Exploration TSXV:ADD characterized its first batch of assays from the Cap property in east-central British Columbia. The news follows last month’s announcement of an extremely rare carbonatite-syenite discovery, suggesting potential for a range of commodities. Now assays for grab samples and the first drill hole show highly anomalous niobium, rare earths and phosphate, the company stated.

Some intervals of
carbonatite from CAP17-004.

Five selected grab samples assayed 0.2% niobium pentoxide, hitting a peak of 0.96% Nb2O5, while three grab samples brought more than 0.2% total rare earth oxides, peaking at 0.39% TREO. Three samples contained over 5% phosphorus pentoxide with a peak value of 12.62% P2O5.

CAP17-004, the first of four drill holes, showed:

  • 0.35% Nb2O5 over 10.42 metres, starting at 85.24 metres in downhole depth
  • (including 0.63% Nb2O5 over 2.26 metres)

  • 9.94% P2O5 over 19.63 metres, starting at 98.87 metres
  • (including 20.97% P2O5 over 2.55 metres)

  • 0.81% TREO over 2.4 metres, starting at 136.1 metres

True widths weren’t provided. The last interval also showed a peak value of 69 ppb gold and over 1% TREO.

Along with sampling and drilling, the summer program included mapping and prospecting over an area of about three kilometres by one kilometre.

“The discovery of highly anomalous concentrations of niobium, phosphate and REOs at such an early stage in the exploration of the Cap project should be considered highly encouraging,” said consulting geologist Jody Dahrouge. “Future exploration at Cap will follow up on surface samples that contained highly anomalous concentrations of niobium and may be related to drill hole CAP17-004.”

Reporting from their Diagras diamond project in the Northwest Territories late last month, Arctic Star and 60% JV partner Margaret Lake Diamonds TSXV:DIA announced geophysical results that could potentially indicate “the largest kimberlite complex in the Lac de Gras field.” Further geophysics are on the 18,699-hectare property’s spring agenda, with drilling to follow.

As for Arctic Star’s recently acquired Timantti diamond project in Finland, assays released in July from historic core on the White Wolf kimberlite showed 111 microdiamonds. The company had earlier found 58 microdiamonds in an 18.9-kilogram sample taken from the same kimberlite.

Timantti covers part of the Fennoscandian Shield, host to major Russian diamond mines Lomonosov and Grib.

In July the company offered a $1.25-million private placement.

Commerce Resources announces successful close of 2016 field season

October 20th, 2016

by Greg Klein | October 20, 2016

A series of hydrogeological tests concluded the 2016 field season as Commerce Resources’ (TSXV:CCE) Ashram rare earths deposit moves towards pre-feasibility. Last month the company finished the year’s definition drilling and environmental data collection on the northeastern Quebec project.

“With the three main field objectives now completed, drill core processing and sample collection for analysis are the next steps,” the company stated.

Still to come are assays from the season’s
14-hole, 2,000-metre, near-surface drill campaign.

The hydrogeological data will help evaluate sub-surface water flow and slope stability of different pit shell configurations. The environmental program included surface water and groundwater samples for baseline data collection and related studies. Last June the Quebec government granted Commerce $300,000 towards studies to optimize tailings management.

The season’s drill program sunk 14 holes totalling about 2,000 metres on the deposit’s northern, western and southern margins. While assays are pending, “initial geologic review and portable XRF data indicates significant mineralization is present over appreciable widths in several holes,” Commerce added. The goal is to expand and upgrade the project’s 2012 high-grade, near-surface resource.

The company keeps busy on a number of fronts as the project advances. Metallurgical studies have simplified Ashram’s flowsheet and shown a potential byproduct in fluorspar. Ashram’s rare earth elements mostly appear in monazite and to a lesser extent bastnasite and xenotime, minerals that dominate commercial extraction processes. Ashram’s REE distribution shows enrichment in the critical and magnet feed elements neodymium, praseodymium, europium, terbium, dysprosium and yttrium.

While rare earths remain the company’s focus, a sampling program on the same property but one kilometre from the deposit brought a “spectacular” result of 5.9% niobium pentoxide last month. Forty out of 64 samples graded above 0.5% Nb2O5, with 16 surpassing 1%. Significant tantalum, phosphate and rare earth oxide grades were also found.

In August the company closed a private placement of $551,040 and the second tranche of a short-form prospectus that totalled nearly $1.45 million.

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

Commerce Resources samples high-grade niobium outside its Ashram rare earths deposit

September 13th, 2016

by Greg Klein | September 13, 2016

An exceptional niobium assay has Commerce Resources TSXV:CCE enthused about an exploration target one kilometre from its Ashram rare earths deposit. A sampling program on the northern Quebec Eldor property strengthens the Miranna area’s niobium-tantalum-phosphate potential, with results up to 5.9% niobium pentoxide. “This is spectacular,” says president Chris Grove. But excited as the company is, work continues to focus on Ashram’s pre-feasibility studies.

A serene-looking camp contrasts with activity
elsewhere on Commerce Resources’ Eldor property.

Of 64 samples, 40 assayed above 0.5% Nb2O5, with 16 surpassing 1%. The program also found significant grades of tantalum, phosphate and rare earth oxides. Two samples each graded above 1,000 ppm Ta2O5 and 1% Nb2O5, while several samples revealed more than 10% P2O5.

The samples also showed appreciable REE mineralization associated with the niobium, Commerce added.

The finding brings to mind the origin of Commerce, which was created around the Upper Fir project in southeastern British Columbia. The property’s Blue River tantalum-niobium deposit reached PEA in 2011 and a resource update in 2013.

Niobium’s price explosion in late 2006 sent Commerce looking for additional deposits, Grove says. That led the company to Eldor. But Ashram’s initial drill results switched the focus to rare earths.

And while Miranna now presents additional multi-commodity potential, work will continue to focus on Ashram’s pre-feas, Grove emphasizes.

The Miranna samples come from a glacial train of niobium-tantalum-phosphate mineralized boulders believed to be near their source. Some mineralized samples hold magnetite, suggesting a magnetic signature to the source. The company says a magnetic high immediately south, which appears to coincide with the train’s apex, could mark the bedrock source.

Previous mineralogical work indicates that Miranna’s niobium and tantalum mineralization is hosted by pyrochlore, the world’s dominant mineral source of niobium, Commerce stated. The pyrochlore’s coarse grains would also benefit recovery.

Meanwhile work continues at Ashram, where a near-surface program of 14 holes totalling 1,600 metres began last month. Metallurgical studies at a mini-pilot plant have simplified the project’s flowsheet. Busy on a number of fronts, a company priority remains producing samples to send to potential JV or offtake partners, who might then take part in the pre-feas.

“It would make sense to have a potential partner offer input on what our production scenario would be,” Grove points out. “We have a huge deposit and we can go bigger, go smaller or stay the same. So advice from a potential partner does make sense before we actually complete the pre-feas.”

Using a 1.25% cutoff, Ashram’s 2012 resource shows 1.59 million tonnes averaging 1.77% total rare earth oxides measured, 27.67 million tonnes averaging 1.9% indicated and 219.8 million tonnes averaging 1.88% inferred. The near-surface deposit remains open to the north and south, and at depth.

Ashram hosts REEs largely in monazite and to a lesser extent bastnasite and xenotime, minerals that dominate commercial extraction. Ashram’s distribution shows enrichment in the critical and magnet feed elements neodymium, praseodymium, europium, terbium, dysprosium and yttrium.
