Lithium-tantalum sampling, new pegmatite discovery position 92 Resources for NWT drill program

January 12th, 2018

by Greg Klein | January 12, 2018

From pilot plant to the field, 92 Resources TSXV:NTY heralded progress on a number of fronts this week. Two days after reporting metallurgical advances for its Hidden Lake lithium project, the company announced high-grade lithium assays, significant tantalum recoveries and the discovery of a seventh pegmatite. The latest news comes from a recently completed eight-day program on the highway-accessible property 40 kilometres east of Yellowknife.

Lithium-tantalum sampling, new pegmatite discovery position 92 Resources for NWT drill program

Last year’s field work added another known pegmatite, as well as
tantalum potential, to 92 Resources’ Hidden Lake lithium project.

Work included channel sampling on two pegmatites discovered in late 2016, HL6 and HL8, near four other known pegmatites on the property. Eight samples from HL6 surpassed 1% Li2O, with values ranging from 1.05% to 2.57%, the latter standing out as the highest 2017 sample grade. Widths extended from 0.75 metres to one metre.

HL8 compensated for lower lithium numbers with some intriguing tantalum results. Of eight samples reported, Li2O values ranged from 0.12% to 0.74%, with Ta2O5 ranging from 114 ppm to 233 ppm. Seven widths came in between 0.74 and 1.33 metres, while a grade of 162 ppm Ta2O5 extended across 5.1 metres.

“Spodumene-bearing pegmatites are often zoned with distinct zones of lithium and tantalum, as well as zones which overlap,” the company explained. “The discovery of tantalum zones in the area is encouraging and bolsters the project’s potential for tantalum, as well as for coupled zones of lithium and tantalum, to be discovered elsewhere on the property.”

Another encouraging sign is a newly discovered pegmatite, bringing Hidden Lake’s known total to seven. An initial sample from HL13 returned 0.48% Li2O.

92 Resources hopes to return early this year, this time with a rig, to begin building a maiden resource.

Earlier this week the company announced another stage of metallurgical studies suggesting Hidden Lake’s pegmatite can produce high-grade concentrate through conventional processing techniques.

Additionally the company holds three lithium properties in Quebec, where sampling from one project brought assays up to 7.32% Li2O and 90 ppm Ta2O5. 92 Resources also plans a 43-101 technical report for its Golden frac sand project in eastern British Columbia.

92 Resources closed a private placement of $1.14 million the previous week and will further fund Hidden Lake with a $140,000 grant from the NWT Mining Incentive Program.

Lithium metallurgy produces high-grade concentrate for 92 Resources’ NWT project

January 10th, 2018

by Greg Klein | January 10, 2018

Showing the advantages of coarse-grained pegmatite, further metallurgical tests on hardrock lithium brought impressive results for 92 Resources’ TSXV:NTY Hidden Lake project in the Northwest Territories. The company processed about 400 kilograms of pegmatite collected last year, putting it through a dense media separation mini-pilot plant. The result brought over 40 kilos of spodumene concentrate averaging a high-grade 6.11% Li2O.

Following last month’s results from heavy liquid separation tests, 92 Resources considers the latest work both highly encouraging and in line with expectations. “The test work continues to support that a final overall concentrate grade of 6% to 6.5% Li2O at high recovery (80% to 85%) is achievable using low-cost and conventional processing techniques,” the company stated.

92 Resources now sees two possible approaches for lithium recovery. The first would use flotation only, which produced the successful results released in December. The second would aim for similar results through a combination of flotation and dense media separation. The dual approach offers lower costs, greater control, shorter start-up time and less risk.

This graphic illustrates the Hidden Lake flowsheet’s dual approach, in which +0.85 mm material undergoes dense media separation to produce concentrate, tailings and middlings. The middlings then combine with the -0.85 mm material to undergo flotation, producing more concentrate and tailings.

Still to come from the test work are tantalum assays, which will be studied for better recovery. The road-accessible 1,849-hectare property sits 40 kilometres east of Yellowknife.

Apart from the Hidden Lake flagship, 92 Resources picked up three hardrock lithium projects in Quebec’s James Bay region last September. Surface samples from the Corvette property showed results up to 7.32% Li2O, along with anomalous tantalum of 90 ppm Ta2O5.

The company also has a 43-101 technical report planned for its Golden frac sand project in eastern British Columbia.

Last week 92 Resources closed a private placement of $1.14 million.

Metallurgy brings high grades, impressive recovery for 92 Resources’ NWT lithium project

December 5th, 2017

by Greg Klein | December 5, 2017

Further metallurgical tests for 92 Resources’ (TSXV:NTY) Hidden Lake hardrock lithium project brought “very encouraging results,” the company reported December 5. Heavy liquid separation and bench scale flotation work produced a concentrate with high grades of 6.2% to 6.5% Li2O, with recovery ranging from an impressive 82% to 85% for pegmatite from the Northwest Territories property.

Metallurgy brings high grades, impressive recovery for 92 Resources’ NWT lithium project

The highway-accessible Hidden Lake property
sits about 40 kilometres east of Yellowknife.

The tests were conducted on material screened above 0.85 mm, but indicated the rest of the material would “respond well to flotation, and that a high overall recovery with a combined concentrate grade above 6% Li2O is achievable” using dense media separation and flotation.

“The metallurgical program has advanced significantly further than we had initially anticipated at this stage,” said president/CEO Adrian Lamoureux. “We have now demonstrated the spodumene has low iron, is coarse-grained and well-liberated, and responds strongly to cost-effective beneficiation techniques to produce high-grade concentrate at high recoveries.”

Tests reported in September showed concentrates had lithium extraction rates up to 97%, he added. “We look forward to completing the remaining Phase II [dense media separation] work and evaluating the next steps in flowsheet development.”

92 Resources filed a 43-101 technical report on the project in January.

The company also holds the Pontax lithium property in Quebec’s James Bay region and the Golden frac sand project in eastern British Columbia.

Exploration begins at Arctic Star’s Finnish diamond project

November 23rd, 2017

Update: On November 24 Arctic Star announced the closing of a final tranche of an oversubscribed private placement totalling $1.7 million.

by Greg Klein | November 23, 2017

Having closed the acquisition a week earlier, Arctic Star Exploration TSXV:ADD now has a crew busy at its Timantti diamond project in Finland. Located among favourable regional infrastructure in the Fennoscandian Shield, which hosts the major Russian diamond mines Lomonosov and Grib, the property has geophysics, sampling and drilling planned.

Timantti’s White Wolf kimberlite has already revealed 169 microdiamonds, 111 from 52.7 metres of historically extracted core and another 58 from an 18.9-kilogram sample. The current program will include ground magnetic, gravity and electromagnetic surveys over the Black and White kimberlites to define their sizes and identify other drill-worthy anomalies.

Additionally, 20 backhoe till samples will be taken to search for diamond indicator minerals. Drilling will consist of about eight holes totalling 1,500 metres, with a 500-kilogram core sample from each of the two kimberlites. Results of the program will determine whether to proceed with bulk sampling.

Work will focus on a 243-hectare area covered by an exploration permit. The project also includes a 95,700-hectare exploration reservation.

Among other projects, Arctic Star holds the Cap property in east-central British Columbia, host to an extremely rare carbonatite-syenite complex that’s potentially associated with several commodities. In September the company reported “highly anomalous” assays for niobium, rare earths and phosphate from sampling and a drill hole.

In the Northwest Territories’ diamondiferous Lac de Gras region, Arctic Star also holds a 40% stake in the Diagras JV, where majority partner Margaret Lake Diamonds TSXV:DIA carried out geophysics last summer.

This week Arctic Star appointed Scott Eldridge as president/CEO. From 2008 to 2016 Eldridge led Euroscandic International Group, providing investment banking and advisory services to resource companies. He has been responsible for raising over $500 million in equity and debt financing for mining projects internationally.

Earlier this month the company closed a private placement first tranche of $965,000.

Canadians need to get past the Klondike to understand mining’s contributions: Stan Sudol

October 13th, 2017

by Greg Klein | October 13, 2017

Rights offerings to be streamlined, says CSA

Like the nugget in this prospector’s hand, the
Klondike’s place in history looms unrealistically large.

The Fraser, Cariboo and Klondike gold rushes undoubtedly played an important nation-building role, with the latter becoming especially famous “thanks to terrific public relations from writers like Jack London, Pierre Berton and Robert Service,” says Stan Sudol. But how important were those events when the Yukon coughed up about 12 million gold ounces, “small change compared to the Timmins camp which is currently at 73 million ounces and counting!”

In a speech to the Canadian Business History Association Conference the Sudbury native and communications consultant/mining strategist/speech writer/mining blogger related how Ontario’s gold and base metals discoveries far surpassed the western gold rushes for their importance to the Canadian economy. “Notwithstanding the historical hype of the Klondike the two most important mining events in our history are the discoveries of the Sudbury nickel mines in 1883 and the Cobalt silver boom of 1903.”

And, he notes, while London, Berton and Service missed out on these developments, Sudbury did attract the attention of Stompin’ Tom Connors.

Sudol outlines the history of the Ontario and Quebec camps, looking at their social and environmental impacts as well as economic contributions. His compelling account takes readers up to the present, as mining in the Northwest Territories and Nunavut helps create an indigenous middle class.

First visit yields surface grades up to 7.32% on 92 Resources’ new Quebec lithium property

A single day of due diligence on a new acquisition brought high lithium values for 92 Resources TSXV:NTY. Selected grab samples from the Corvette property in northern Quebec assayed 0.8%, 3.48% and 7.32% Li2O at surface from one pegmatite outcrop and 1.22% from another, which also showed an anomalous tantalum result of 90 ppm Ta2O5.

The 3,891-hectare property comprises one of three prospective lithium acquisitions in Quebec’s James Bay region announced last month.

The two spodumene-bearing pegmatites, about 75 metres apart and trending sub-parallel, “highlight the prospective nature of the property,” 92 Resources stated. With only a small part of the property explored so far, the company has more prospecting as well as channel sampling planned before winter sets in.

In September the company announced a two-week program of prospecting and channel sampling at its flagship Hidden Lake lithium project in the Northwest Territories. Follow-up metallurgical results released the same month on a concentrate produced from Hidden Lake material showed an overall extraction rate of 97%.

92 Resources also has a 43-101 technical report planned for its Golden frac sand project in eastern British Columbia.

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.

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.

92 Resources adds three Quebec properties to its lithium portfolio

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.

92 Resources advances NWT hardrock lithium metallurgy

Follow-up tests using standard methods brought high-grade lithium results for 92 Resources’ (TSXV:NTY) Hidden Lake project in the Northwest Territories. After further work on a spodumene-montebrasite concentrate of 6.16% Li2O produced in July, the company now reports an overall extraction rate of 97%. The tests consisted of roasting followed by acid baking and water leaching, industry-standard extraction techniques for lithium, 92 Resources stated.

The next stage calls for magnetic separation, heavy liquid separation and additional flotation on material collected during the current field program. So far work has used analytical reject material, but whole rock material will be preferred for Phase II, the company added.

Earlier this month a crew returned to the property, about 40 kilometres by road from Yellowknife, for a program of channel sampling and prospecting for additional pegmatites.

The summer agenda also included field work at the company’s Golden frac sand project in eastern British Columbia. The property sits adjacent to Heemskirk Canada’s Moberly project, a former source of silica sand for the glass industry that’s now being redeveloped as a frac sand production and processing operation.
