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’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

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.

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.

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

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.

Update: 92 Resources explores polymetallic potential of Quebec’s James Bay region

July 8th, 2019

by Greg Klein | updated July 8, 2019

Lithium, gold, copper and molybdenum are among the goals of a program now underway at 92 Resources’ (TSXV:NTY) Corvette-FCI project. A four-person crew expects to spend three to four weeks on the property, which consists of 92’s 100%-held Corvette claims as well as the FCI-East and FCI-West turf, optioned under a 75% earn-in from Osisko Mining TSX:OSK. Work will be conducted by Dahrouge Geological Consulting.

92 Resources to explore polymetallic potential of Quebec’s James Bay region

Over a campaign of three to four weeks, 92 Resources hopes to
build on previous success with energy, precious and base metals.

The agenda calls for prospecting along with rock and soil sampling. Among the priorities will be the Golden Gap Prospect at FCI-West, where historic, non-43-101 outcrop samples have graded between 3.1 g/t and 108.9 g/t gold, along with an historic drill intercept of 10.5 g/t over seven metres and a channel sample of 14.5 g/t over two metres.

Past reports of molybdenum occurrences on the area’s southern copper trend will also come under scrutiny.

The Lac Bruno prospect provides another area of interest, where a boulder field produced 13 samples exceeding 1 g/t gold, with one sample hitting 38.1 g/t. Up-ice soil sampling will extend from FCI-East to the boulders’ interpreted source on 92’s wholly owned Corvette claims.

Energy metals also attract interest, as the company’s previous work identified a well-mineralized lithium pegmatite system over a strike extending at least three kilometres on Corvette, with further potential on FCI-East. Lithium-tantalum channel samples released last year from Corvette’s CV1 pegmatite averaged 1.35% Li2O and 109 ppm Ta2O5, reaching as high as 2.28% Li2O and 471 ppm Ta2O5 over six metres. Three other spodumene-bearing pegmatites also show promise.

Located within the Guyer group of the Greater La Grande Greenstone Belt, the property sits about 10 kilometres south of the all-season Trans-Taiga Road and powerline, adjacently south of Midland Exploration’s (TSXV:MD) Mythril copper-gold-molybdenum-silver project and immediately east of Pikwa, a polymetallic project of Azimut Exploration TSXV:AZM and Ressources Québec’s SOQUEM subsidiary.

92’s Quebec portfolio also includes the Pontax, Eastman and Lac du Beryl properties. Grab samples from Pontax have reached up to 0.94% Li2O and 520 ppm Ta2O5.

In British Columbia 92 holds the Silver Sands vanadium prospect and the Golden frac sand project, the latter adjacent to Northern Silica’s high-grade Moberly silica mine and subject of a 43-101 technical report filed by 92 last year.

In the Northwest Territories, the company has a 40% stake in the Hidden Lake lithium project, with Far Resources CSE:FAT holding the remainder. In a 1,079-metre drill program last year, all 10 holes found grades above 1% Li2O, with one intercept showing 1.6% over 9.2 metres. Using Hidden Lake material, a mini pilot plant produced 40 kilograms of concentrate grading 6.11% Li2O with recovery over 80%.

Commerce Resources to provide rare earths and byproduct samples to potential customers

Commerce Resources to provide rare earths and byproduct samples to potential customers

 

With trade tensions once again demonstrating the need for rare earths supply outside China, Commerce Resources TSXV:CCE announced plans for its advanced-stage Ashram deposit in northern Quebec. The company intends to resume pilot plant metallurgical work, provide rare earths samples to interested parties and also upgrade its potential fluorspar byproduct.

Using lab facilities in Colorado, Commerce plans to produce several kilograms of material for companies that have requested samples. The lab will also work on upgrading the deposit’s fluorspar from metallurgical grade to the usually more expensive acid grade.

An essential ingredient for coolants used in refrigerators, freezers and air conditioners, acid grade fluorspar is also integral to processing uranium and aluminum. Like rare earths, fluorspar ranks among the 35 critical minerals listed by the United States. Over 60% of 2018 global production came from China, according to U.S. Geological Survey data. NorFalco Sales, a division of Glencore Canada Corp, has requested the fluorspar sample.

The pilot plant work will complement Commerce’s pre-feasibility studies as the Ashram deposit progresses.

Using Ashram material, the Colorado plant has already produced high-grade concentrates above 45% total rare earth oxides with recovery surpassing 70%, “comparable to current and past hard rock producers,” Commerce noted.

Separate, Quebec-funded studies at l’Université Laval produced a mixed rare earth oxide concentrate from Ashram material, showing the deposit’s versatility to processing procedures.

A key advantage of Ashram lies in its carbonatite-hosted mineralization and relatively simple monazite, bastnasite and xenotime mineralogy, amenable to conventional rare earths processing.

The near-surface deposit hosts a 2012 resource estimate using 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

Ashram also features strong distribution of the high-demand magnet feed elements neodymium, praseodymium, dysprosium and terbium.

In a report issued last month, Adamas Intelligence stated that permanent magnets accounted for over 90% of TREO consumption by value last year. “This share is poised to expand further as demand (and prices) for neodymium, praseodymium, dysprosium and terbium continue to rise strongly in the years ahead.”

Ashram’s distinctions suggest the project could require a relatively smaller metallurgical plant, along with potentially lower capex and opex, Commerce stated.

Last May Commerce and two Inuit organizations signed a letter of intent to ensure participation as the project moves forward.

At another critical minerals project just a few kilometres away, Saville Resources TSXV:SRE works towards a 75% earn-in from Commerce on the Niobium Claim Group. Following a spring drill program that found high-grade, near-surface niobium along with tantalum and phosphate, Saville looks forward to a Phase II campaign.

In southern British Columbia, Commerce also holds the advanced-stage Blue River tantalum-niobium deposit.

Saville Resources/Commerce Resources release niobium-tantalum-phosphate results from northern Quebec

June 13th, 2019

In three batches during early June 2019, Saville Resources TSXV:SRE and Commerce Resources TSXV:CCE released assays from the first drill program in nine years on the Niobium Claim Group in Quebec’s Labrador Trough. Saville operates the program under a 75% earn-in from Commerce, which is advancing its Ashram rare earths deposit towards pre-feasibility.

Of five holes totalling 1,049 metres, one hole was lost. The other four exceeded near-surface high grades and wide widths of historic drilling conducted between 2008 and 2010, the companies stated. Previous campaigns totalled 41 holes for 8,175 metres.

Here are highlights from the spring 2019 program. True widths weren’t provided. Fluorine results are still to come.

Towards a critical resource

Saville Resources exceeds historic high grades for niobium-tantalum in Quebec

by Greg Klein

The project’s first drill campaign in nine years poses a big question: Why was this the project’s first drill campaign in nine years?

Saville Resources/Commerce Resources report best-yet niobium hole from Quebec critical minerals project

Saville president Mike Hodge examines
core at the Niobium Claim Group.

Even in the face of highly encouraging historic niobium-tantalum results, this program’s first hole exceeded expectations. More near-surface high grades and wide widths followed, culminating in a fourth hole that surpassed them all. Now Saville Resources TSXV:SRE looks forward to more drilling to build an inferred resource on the Niobium Claim Group in northern Quebec’s Labrador Trough.

But why the nine-year hiatus? The answer can be illustrated by Commerce Resources’ (TSXV:CCE) Ashram rare earths deposit, two kilometres away. Moving that project towards pre-feasibility took precedence, even when the company found strong niobium-tantalum intercepts on another part of its Eldor property. To give these other critical minerals their due, Commerce and Saville signed an agreement last year allowing the latter company to earn 75% of the 1,223-hectare niobium claims.

Additional high-grade boulder samples renewed interest in a number of prospective areas but Saville’s initial drill program in spring 2019 targeted Mallard, the most advanced zone with 17 historic holes totalling 4,328 metres. The new program added five holes (one hole was lost) and 1,049 metres.

“We were confident that we could improve on the historic drill results and we did that,” notes Saville president Mike Hodge.

Near-surface highlights from the best hole showed 0.8% Nb2O5 over 31.5 metres, 0.79% over 37 metres, 0.67% over 19.95 metres and 0.5% over 33.5 metres. Eleven individual samples from that hole exceeded 1%, with one sample reaching as high as 1.68% over 1.5 metres. (True widths were unknown.) Tantalum and phosphate also brought strong numbers.

A 50-metre step-out east of another of the campaign’s successful holes, 50 metres southeast of a second and 200 metres southeast of a third, EC19-174A was also proximal to impressive historic results.

Saville Resources exceeds historic high grades for niobium-tantalum in Quebec

In just a few of the recent highlights, however, EC19-173 featured 0.66% Nb2O5 over 14.5 metres. EC19-171 hit 0.7% over 38.28 metres, including 1.1% over 5.41 metres. EC19-172 reached 0.62% over 19 metres.

Among tantalum grades were 274 ppm Ta2O5 over 100.8 metres from EC19-172, and 267 ppm over 26 metres from EC19-171.

The step-outs extend Mallard’s strike 100 metres southeast and also suggest a possible northern extension towards the project’s Miranna and Spoke targets, as yet undrilled.

That’s despite very high-grade boulder samples from Miranna showing 2.75%, 4.24%, 4.3% and an exceptional 5.93% Nb2O5.

“These are still untested targets which we believe could have significantly higher grades than Mallard,” says Hodge. “But my first goal would be an inferred near-surface resource in the Mallard area.”

Contributing to that would be historic data, which includes intervals of 0.82% Nb2O5 over 21.9 metres, 0.9% over 4.8 metres and 1.09% over 5.8 metres.

In all, the Niobium Claim Group underwent 41 historic holes for 8,175 metres, with all field work since 2008 conducted by Dahrouge Geological Consulting. Saville has so far exceeded its first-year spending commitment of $750,000 out of a five-year, $5-million exploration agenda that would earn 75% of the project from Commerce.

But if Miranna’s 5.93% Nb2O5 sample looks outstanding, another boulder collected west of the project’s Northwest area soared up to 16.1%, also showing 7,540 ppm Ta2O5.

“That was the highest, but there were plenty in the 3% to 6% niobium range,” Hodge emphasizes.

With overlapping boulder trains on the property, “there are a few locations they could be coming from,” he adds. “But the likelihood of it coming from the Spoke or Miranna areas would be the highest probability.”

Other areas of interest include the Northwest zone, northwest of Miranna. Location of 11 historic holes totalling 2,257 metres, its results included 0.61% Nb2O5 over 12 metres.

South of Mallard, the Star Trench area has four historic holes for 664 metres, with results including 1.5% Nb2O5 and 1,810 ppm Ta2O5 over 0.52 metres, and 1.69% Nb2O5 and 2,220 ppm Ta2O5 over 0.31 metres.

Niobium and tantalum both rank on the U.S. list of 35 critical minerals. Heightened concern has brought concerted American efforts to develop reliable sources and create supply chains domestically and with allied countries. In early June the U.S. unveiled its Energy Resource Governance Initiative to work with allies as part of the president’s critical minerals strategy announced a few days earlier.

Imports provide America’s total supply of both niobium and tantalum. Niobium, used for alloys and super-alloys in jet engines, rockets and other manufactures, comes to the U.S. mostly from one company in Brazil. According to 2018 figures from the U.S. Geological Survey, Brazil mined 88.2% of global supply, while Canada extracted another 10.3%.

Tantalum finds widespread use in electronics as well as super-alloys for jet engine components. USGS numbers from last year attribute 39.5% of global supply to the Democratic Republic of Congo, 27.8% to Rwanda, 8.3% to Nigeria and 6.7% to China. Apart from security of supply, concerns about conflict minerals result from troubling conditions and murky supply routes in the DRC and Rwanda.

Meanwhile Hodge wants to get back to the field. “We made a great first step in expanding on what we had,” he says. “All of these holes ended in a mineralized zone. The reason we stopped them there was to start a near-surface inferred resource. There’s carbonatite with mineralization in niobium, tantalum and phosphate open in all directions, so the results definitely call for more drilling.”
