92 Resources adds three Quebec properties to its lithium portfolio

September 21st, 2017

by Greg Klein | September 21, 2017

While work continues on the flagship Hidden Lake project in the Northwest Territories, 92 Resources TSXV:NTY expanded its holdings with three more lithium prospects. All located in Quebec’s James Bay region, the newcomers total 5,953 hectares, with each property showing pegmatite outcrop.

An outcrop on the Corvette acquisition shows coarse-
grained spodumene crystals with lengths up to a metre.

The 3,891-hectare Corvette property hosts an outcrop measuring about 150 metres by 30 metres showing abundant coarse-grained spodumene crystals up to one metre in length, the company stated. Other potential pegmatite outcrops along trend are priorities for follow-up work.

Sitting less than 12 kilometres from an all-weather highway, Corvette covers the eastern continuation of the Guyer greenstone belt, offering precious metals potential as well.

On the 1,109-hectare Eastmain property, 92 Resources interprets a large pegmatite outcrop to be along strike from ASX-listed Galaxy Resources’ James Bay deposit. An all-weather highway passes less than seven kilometres away.

The 953-hectare Lac du Beryl property features several pegmatite outcrops, “many of which display characteristic pathfinder minerals commonly associated with spodumene pegmatites,” the company added. Lac du Beryl sits 16 kilometres from a transmission line.

Three days earlier 92 Resources reported a 97% overall extraction rate on a spodumene-montebrasite concentrate produced from Hidden Lake material. The tests used industry-standard techniques, the company stated. Phase II tests are planned while a two-week channel sampling program wraps up.

In eastern British Columbia, the company also holds the Golden frac sand project, which underwent a 10-day field program this summer.

BonTerra Resources heralds new gold zone in Quebec’s Urban-Barry camp

September 14th, 2017

by Greg Klein | September 14, 2017

Exploration drilling southwest of the Gladiator deposit reveals a new gold zone, BonTerra Resources TSXV:BTR announced. Christened the Temica zone, it’s believed to be an extension of the deposit’s mineralized trend. Of three holes with one intercept each reported September 14, the standout was CL-17-14, four kilometres from the deposit. The result showed 4.7 g/t gold and 44.6 g/t silver over 2.7 metres, at 250 metres below surface.

BonTerra’s field camp houses a team
busy with a 40,000-metre 2017 program.

Another kilometre southwest, CL-17-06 found 13 g/t gold over one metre at 200 metres below surface. CL-17-01 showed a near-surface 4.8 g/t gold over one metre in “close proximity to drill hole CL-17-14, but was located too close to the zone and resulted in a partial intersection,” BonTerra stated.

True widths were estimated between 60% and 80%.

The discovery follows till sampling and induced polarization surveys that identified additional targets for further drilling that’s planned for Temica and beyond.

BonTerra last released assays in July from a campaign largely focused on the gap between the 8,126-hectare Coliseum property’s Gladiator deposit and the Rivage zone, about 600 metres west.

With at least four rigs busy on a planned 40,000 metres, all that drilling can only stir anticipation of an update to Gladiator’s 2012 resource. Using a base case 4 g/t cutoff, it holds an inferred category of 905,000 tonnes averaging 9.37 g/t for 273,000 ounces gold. The deposit remains open in all directions.

The company raised $40 million this year, with participation from Eric Sprott and Kinross Gold TSX:K.

BonTerra also holds the Larder Lake project in Ontario’s Cadillac/Larder Lake break. The property’s Bear Lake deposit has an historic, non-43-101 inferred resource of 3.7 million tonnes averaging 5.7 g/t for 683,000 gold ounces. Another non-43-101 estimate for the Cheminis deposit has an indicated 335,000 tonnes averaging 4.1 g/t for 43,800 gold ounces and an inferred 1.39 million tonnes averaging 5.2 g/t for 233,400 ounces.

Aurvista Gold adds greenfields exploration to resource expansion at Abitibi project

September 12th, 2017

by Greg Klein | September 12, 2017

Successful financing doesn’t rule out cautious spending for Aurvista Gold TSXV:AVA. Having raised $10.1 million in July, the company spent the summer reconsidering the Douay project’s strategy. Working with Aurvista’s geological consultants, a newly appointed technical advisory committee developed an approach incorporating both brownfields and greenfields exploration for the recently expanded 33,170-hectare property on Abitibi’s Casa Berardi deformation zone. Work continues on sampling, re-logging previous core, and reviewing geological, geochemical and geophysical data.

Aurvista Gold adds greenfields exploration to resource expansion at Abitibi project

Aurvista has another winter drill
program slated for this year.

To cut helicopter-borne costs, diamond drilling has been deferred to winter. But the committee also recommended a property-scale reverse circulation program “or similar top-of-bedrock sampling program to provide critically important geochemical data,” Aurvista stated.

Douay’s brownfields area hosts two types of gold mineralization, the company added. Seven zones from both areas contributed to last April’s resource update with an inferred total of 83.33 million tonnes averaging 1.05 g/t for 2.81 million gold ounces at a 0.5 g/t cutoff.

Higher grades hosted in altered mafic volcanics can be found in the Douay West zone, with its inferred 4.47 million tonnes averaging 2.36 g/t. Altered porphyritic rocks offer lower grades, such as the Porphyry zone, with its inferred 72.16 million tonnes averaging 0.96 g/t.

The resource remains open along strike and plunge, providing excellent expansion potential, the company emphasized. But Aurvista also sees potential in Douay’s relatively unexplored area for VMS, mafic, porphyry and other styles of mineralization.

Indications of Douay’s future might come from the past as well. A huge relogging program has been underway to simplify the project’s geological model. Still to be completed are about 27,000 metres out of a 220,000-metre archive dating to 1976. Oddly enough, a lot of that core was never assayed for gold. The team intends to prepare about 18,000 samples for lab analysis.

Once targets have been refined, Aurvista plans to spend the bulk of its treasury on diamond drilling both greenfields and brownfields targets, with the rigs resuming their work this winter.

In July the company released final assays from Douay’s previous 59-hole, 23,965-metre program.

Castle Silver Resources to study possible new plant and processing deal with Granada Gold Mine

September 11th, 2017

by Greg Klein | September 11, 2017

A gold milling arrangement now under consideration could offer synergies to two companies with overlapping management, directors and staff. Under an MOU signed by Castle Silver Resources TSXV:CSR and Granada Gold Mine TSXV:GGM, Castle Silver will study the potential installation of a 600-tpd gravity flotation plant at one of its northern Ontario properties. The facility would process feed from the proposed Granada gold mine across the Quebec border near Rouyn-Noranda. Castle Silver expects to complete the study in Q4.

Castle Silver Resources to study possible new plant and processing deal with Granada Gold Mine

Granada’s proposed mine reached pre-feas
in 2014 and a resource update in May.

A resource update released last May used a 0.39 g/t cutoff to show an in-pit measured and indicated total of 21.57 million tonnes averaging 1.16 g/t for 807,700 gold ounces. An underground inferred category for an area north of the potential open pit used a 1.5 g/t cutoff for 10.38 million tonnes averaging 4.56 g/t for 1.52 million ounces. Granada stated the new 43-101 supersedes the pre-feasibility report released in 2014.

The company describes its project as fully permitted, shovel-ready and one of the region’s largest undeveloped gold projects.

Meanwhile Castle Silver waits on assays for its namesake flagship, where summer drilling sunk 22 holes totalling 2,405 metres. Chip and bulk sampling results from the former underground silver mine have returned gold, cobalt and nickel grades in addition to silver. More bulk sampling is planned.

Castle Silver has raised $2.6 million since March.

Price/supply concerns draw end-users to Commerce Resources’ rare earths-tantalum-niobium projects

by Greg Klein

“One of the things that really galls me is that the F-35 is flying around with over 900 pounds of Chinese REEs in it.”

That typifies some of the remarks Commerce Resources TSXV:CCE president Chris Grove hears from end-users of rare earths and rare metals. Steeply rising prices for magnet feed REEs and critical minerals like tantalum—not to mention concern about stable, geopolitically friendly sources—have brought even greater interest in the company’s two advanced projects, the Ashram rare earths deposit in northern Quebec and the Blue River tantalum-niobium deposit in southeastern British Columbia. Now Commerce has a list of potential customers and processors waiting for samples from both properties.

Of course with China supplying over 90% of the world’s REEs, governments and industries in many countries have cause for concern. Tantalum moves to market through sometimes disturbingly vague supply lines, with about 37% of last year’s production coming from the Democratic Republic of Congo and 32% from Rwanda, according to the U.S. Geological Survey. One company in Brazil, CBMM, produces about 85% of the world’s niobium, another critical mineral.

As Ashram moves towards pre-feasibility, Commerce has a team busy getting a backlog of core to the assay lab. But tantalum and niobium, the original metals of interest for Commerce, have returned to the fore as well, with early-stage exploration on the Quebec property and metallurgical studies on the B.C. deposit.

The upcoming assays will come from 14 holes totalling 2,014 metres sunk last year, mostly definition drilling. Initial geological review and XRF data suggest significant intervals in several holes, including a large stepout to the southeast, Grove’s team reports.

“We’re always excited to see this project’s drilling results,” he says. “We know we’re in carbonatite basically all of the time and over the last five years, in all the 9,200 metres we’ve done since the last resource calculation, we’ve basically always hit more material than was modelled in the original resource—i.e. we’ve always found less waste rock at surface, we’ve always hit material in the condemnation holes and we’ve always had intersections of higher-grade material. So all those things look exciting for this program.”

Carbonatite comprises a key Ashram distinction. The deposit sits within carbonatite host rock and the minerals monazite, bastnasite and xenotime, which are well understood in commercial REE processing. That advantage distinguishes Ashram from REE hopefuls that foundered over mineralogical challenges. Along with resource size, mineralogy has Grove confident of Ashram’s potential as a low-cost producer competing with China.

As for size, a 2012 resource used a 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

A near-surface—sometimes at-surface—deposit, Ashram also features strong distribution of neodymium, europium, terbium, dysprosium and yttrium, all critical elements and some especially costly. Neodymium and dysprosium prices have shot up 80% this year.

Commerce Resources’ field crew poses at the Eldor property,
home to the Ashram deposit and Miranna prospect.

Comparing Ashram’s inferred gross tonnage of nearly 220 million tonnes with the measured and indicated total of less than 30 million tonnes, Grove sees considerable potential to bolster the M&I as well as increase the resource’s overall size and average grade.

This season’s field program includes prospecting in the Miranna area about a kilometre from the deposit. Miranna was the site of 2015 boulder sampling that brought “spectacular” niobium grades up to 5.9% Nb2O5, nearly twice the average grade of the world’s largest producer, CBMM’s Araxá mine, Grove says. Some tantalum standouts showed 1,220 ppm and 1,040 ppm Ta2O5. Significant results for phosphate and rare earth oxides were also apparent.

Should Miranna prove drill-worthy, the synergies with Ashram would be obvious.

That’s the early-stage aspect of Commerce’s tantalum-niobium work. In B.C. the company’s Blue River deposit reached PEA in 2011, with a resource update in 2013. Based on a tantalum price of $381 per kilo, the estimate showed:

  • indicated: 48.41 million tonnes averaging 197 ppm Ta2O5 and 1,610 ppm Nb2O5 for 9.56 million kilograms Ta2O5 and 77.81 kilograms Nb2O5

  • inferred: 5.4 million tonnes averaging 191 ppm Ta2O5 and 1,760 ppm Nb2O5 for 1 million kilograms Ta2O5 and 9.6 million kilograms Nb2O5

Actually that should be 1,300 kilograms less. That’s the size of a sample on its way to Estonia for evaluation by Alexander Krupin, an expert in processing high-grade tantalum and niobium concentrates. “As with Ashram, we’ve already found that standard processing works well for Blue River,” Grove points out. “However, if Krupin’s proprietary method proves even more efficient, why wouldn’t we look at it?”

We’re always excited to see this project’s drilling results. We know we’re in carbonatite basically all of the time and over the last five years, in all the 9,200 metres we’ve done since the last resource calculation, we’ve basically always hit more material than was modelled in the original resource.—Chris Grove,
president of Commerce Resources

Back to rare earths, Commerce signed an MOU with Ucore Rare Metals TSXV:UCU to assess Ashram material for a proprietary method of selective processing. Others planning to test proprietary techniques on Ashram include Texas Mineral Resources and K-Technologies, Rare Earth Salts, Innovation Metals Corp, the University of Tennessee and NanoScience Solutions at Tufts University in Massachusetts.

Should proprietary methods work, all the better, Grove states. But he emphasizes that standard metallurgical tests have already succeeded, making a cheaper process unnecessary for both Blue River and Ashram.

Potential customers show interest too. Concentrate sample requests have come from Solvay, Mitsubishi, Treibacher, BASF, DKK, Albemarle, Blue Line and others covered by non-disclosure agreements. Requests have also come for samples of fluorspar, a potential Ashram byproduct and another mineral subject to rising prices and Chinese supply dominance.

A solid expression of interest came from the province too, as Ressources Québec invested $1 million in a February private placement. The provincial government corporation describes itself as focusing “on projects that have good return prospects and foster Quebec’s economic development.”

Also fostering the mining-friendly jurisdiction’s economic development is Plan Nord, which has pledged $1.3 billion to infrastructure over five years. The provincial road to Renard helped make Stornoway Diamond’s (TSX:SWY) mine a reality. Other projects that would benefit from a road extension towards Ashram would be Lac Otelnuk, located 80 kilometres south. The Sprott Resource Holdings TSX:SRHI/WISCO JV holds Canada’s largest iron ore deposit. Some projects north of Ashram include the Kan gold-base metals project of Barrick Gold TSX:ABX and Osisko Mining TSX:OSK, as well as properties held by Midland Exploration TSXV:MD.

But, Grove says, it’s rising prices and security of supply that have processors and end-users metaphorically beating a path to his company’s door. And maybe nothing demonstrates the criticality of critical minerals better than a nearby superpower that relies on a geopolitical rival for commodities essential to national defence.

Aurvista Gold expands its Abitibi presence, readies fall/winter drilling

September 5th, 2017

by Greg Klein | September 5, 2017

New expertise, new financings and now new turf have Aurvista Gold TSXV:AVA looking forward to another season of drilling on its Douay project in Quebec’s Abitibi region. With even more expansion planned, the company has extended the property by over 2,600 hectares, for a total of 33,170 hectares offering potential for “high-quality drill targets within and beyond the known resource areas.”

Additional claim applications would raise that to 34,500 hectares, covering a 50-kilometre segment of the Casa Berardi deformation zone.

The new land sits contiguously to ground staked last April and covers two of Casa Berardi’s three main faults. The project’s main mineralization is located “on a splay fault off the northern-most fault of the Casa Berardi break in an area of chaotic magnetic signatures due to the presence of intrusive porphyries, magnetic units and alteration,” Aurvista stated. “The recently staked claims cover another area of chaotic magnetic signatures 20 kilometres to the northwest.”

Other near-term announcements should include plans for fall/winter exploration and drilling currently under preparation by Aurvista’s geologists and newly appointed technical advisory committee. The new program would follow spring/summer drilling that totalled 59 holes for 23,965 metres.

A resource last updated in April showed an inferred category for seven zones totalling 83.3 million tonnes averaging 1.05 g/t for 2.81 million gold ounces at a 0.5 g/t cutoff.

After originally offering a private placement up to $7 million, Aurvista closed financings totalling $10.1 million in July.

Update: Berkwood Resources continues to drill visible graphite in Quebec

August 31st, 2017

by Greg Klein | updated August 31, 2017

Assays have yet to arrive, but two holes reported last week and another five on August 31 have all produced near-surface core with visible graphite from Berkwood Resources’ (TSXV:BKR) Lac Gueret South project. The Phase I program calls for nine more shallow holes between about 60 and 120 metres in depth.

The company cautioned that visible indications don’t necessarily coincide with significant grades. But the results do justify continuing the program as planned, Berkwood stated.

Lac Gueret South borders the property hosting Mason Graphite’s (TSXV:LLG) high-grade graphite deposit. A 2014 airborne EM survey over Berkwood’s land found several zones of high conductivity.

Last week’s news from the property’s Site #1 reported 3.1 metres and 38.29 metres of visible graphite from BK1-01-17, along with 2.7 metres and 9.9 metres from BK1-02-17. The depths corresponded with electromagnetic conductors.

The first seven holes have brought observable
encouragement to Berkwood Resources’ Lac Gueret South.

Among new findings from Site #2, about 110 metres north, BK1-03-17 displayed the right stuff in seven intervals ranging between 1.46 metres and 28.2 metres in width.

Another Site #2 hole, BK1-04-17 showed graphite “continuously from 26.7 metres to 79.24 metres in variable amounts and styles,” Berkwood stated.

At Site #3, another 65 kilometres north, BK1-05-17 revealed graphite over four intervals with thicknesses between 3.2 metres and 14.12 metres. BK1-06-17 brought intervals of 13.22 metres and 1.14 metres.

About 87 metres east, BK1-07-17 on Site #4 showed 5.94 metres of graphite.

True widths weren’t provided.

The company holds two land parcels adjacent to the Mason property, Berkwood’s 100%-optioned, 5,714-hectare Lac Gueret South and the 100%-held, 2,052-hectare Lac Gueret East. The properties sit about three hours by road from the deep-sea port of Baie-Comeau.

Last month the company announced acquisition of the Delbreuil property in Quebec’s Abitibi, where an historic, non-43-101 sample assayed 1,290 ppm lithium and 126 ppm tantalum. Historic drill results also showed zinc, nickel, copper, silver and cobalt.

In another energy mineral acquisition last June, Berkwood announced an agreement to take on the Cobalt Ford property, located about four hours’ driving time from Baie-Comeau. Historic, non-43-101 work suggests prospectivity for base metals as well as cobalt.

This week the company closed private placements totalling $985,180.

Aurvista Gold names technical advisory committee for Abitibi advancement

July 27th, 2017

by Greg Klein | July 27, 2017

Flush with $10.1 million in recent financings and data from an extensive drill campaign, Aurvista Gold TSXV:AVA continues to beef up its personnel. Three days after announcing nominees for an expanded board of directors, the company named its appointees to a newly created technical advisory committee to help further the Douay gold project in Quebec’s Abitibi.

Aurvista Gold names technical advisory committee for Abitibi advancement

“We are in a period of growth and transition and will continue putting the best people, processes and systems in place,” said president/CEO Matthew Hornor, himself a newcomer as of last May. “We are going to take a hard look at all of the project data and results to date and complete the necessary exploration and preparation work to ensure our technical decision-makers have the information and resources required to succeed.”

Just nominated to the board of directors, David Broughton and Maurice Tagami join the advisory committee as well.

Mining engineer R. Dennis Bergen’s 40-plus years of experience include managing the Golden Bear gold mine in northern British Columbia, the Cantung tungsten mine in the Northwest Territories and the Ketza River gold mine in the Yukon.

Electrical engineer John Casson specializes in infrastructure design, project evaluation and implementation analysis in world class mining and beneficiation projects. He has held senior positions on major projects including Voisey’s Bay, Mary River and the El Aouj iron ore project in Mauritania.

Previously Aurvista’s president/CEO, Jean Lafleur now moves from his current position as VP of exploration into the advisory committee. He was instrumental in discovering new reserves for McWatters Mining gold projects in the Val-d’Or and Malartic camps, as well as developing a bulk gold exploration program at the Canadian Malartic property.

Thanking Lafleur for his service, Hornor said, “He has done an admirable job leading exploration and will continue to be a key contributor as we shift to a committee approach to integrate some of the brightest minds in the industry into our exploration planning and strategy going forward.”

Aurvista’s 30,500-hectare Douay project has a highway and transmission lines crossing the property and benefits from the Abitibi region’s labour, supplies and services. A March resource update, using a 0.5 g/t cutoff, calculated an inferred category for seven zones totalling 83.3 million tonnes averaging 1.05 g/t for 2.81 million gold ounces.

The recently completed spring/summer drill program totalled 59 holes and 23,965 metres.
