Outcrops, pegmatites and spodumene mean lithium for 92 Resources

92 Resources’ James Bay-region Corvette property features
drill-ready targets as well as 15 kilometres of potential strike to evaluate.

 

An early-stage but steadily advancing project shows 92 Resources TSXV:NTY focusing firmly on northern Quebec’s lithium. Successful field work so far has inspired two large property expansions, one in a deal with Osisko Mining TSX:OSK. Now with about 15 kilometres of potential strike length in one package, 92 hopes to prove up grade and tonnage to bring its Corvette property to an advanced level.

A series of outcrops reveals lithium along with tantalum occurring in spodumene-bearing pegmatite over at least two sub-parallel structures, explains Darren Smith. “We have drill-ready targets as well as lots of highly prospective ground to explore.” Having worked with the company for about two years through Dahrouge Geological Consulting and been a 92 advisory board member since July, he’s obviously enthusiastic about the project.

optimistic about Corvette’s deeper potential.

And as a resident of Quebec City, he likes the jurisdiction too. “Quebec offers a lot of provincial support for mining,” Smith points out. “Also our Quebec projects fall within the James Bay Northern Quebec Agreement, which has structures in place for First Nations engagement and resource management.”

Corvette marked a change of direction for the company, after 92 optioned its Hidden Lake lithium property in the Northwest Territories to Far Resources CSE:FAT last January. Despite that project’s favourable sampling and metallurgical results, 92 saw even greater potential in its Quebec acquisitions. The theory found support from subsequent channel sampling grades and widths.

In September 92 released assays from 40 channel samples taken on the property’s CV1 pegmatite that averaged 1.35% Li2O. Tantalum showed up too, grading an average 109 ppm Ta2O5. Some highlights revealed:

  • 1.54% Li2O and 136 ppm Ta2O5 over 8 metres

  • 1.77% Li2O and 54 ppm Ta2O5 over 6 metres

  • 1.36% Li2O and 128 ppm Ta2O5 over 11 metres

  • 1.2% Li2O and 128 ppm Ta2O5 over 4 metres

  • 1.02% Li2O and 95 ppm Ta2O5 over 11 metres

About 50 metres north, the CV2 pegmatite showed:

  • 0.73% Li2O and 140 ppm Ta2O5 over 4 metres

  • 0.55% Li2O and 136 ppm Ta2O5 over 4 metres

True widths weren’t known.

Another promising development was the discovery of two more spodumene-bearing pegmatites. A grab sample grading 1.61% Li2O came from CV3, about 250 metres south of CV1. A 0.74% grab sample marked CV4, about three kilometres northeast and along strike of CV1.

“We’re looking for tonnage and grade, and the grade has been demonstrated to be quite favourable,” Smith says. “The program added more tonnage potential through the CV3 and CV4 pegmatites, which show there might be multiple parallel structures. Because we have large occurrences over a three-kilometre strike length, it is inferred that it could be decent depth and that’s how to build tonnage. So now we have a structure over three kilometres along strike with mineralized spodumene-bearing pegmatite at either end. This is very positive because pegmatites tend to occur in swarms and congregations.”

The potential strike could be much greater yet, thanks to recent property expansions. In August the company staked another 4,918 hectares, more than doubling Corvette’s size. The following month 92 announced a 75% earn-in on Osisko’s neighbouring FCI claims, adding 14,034 hectares to the project and putting a potential strike of 15 kilometres into one package.

“Satellite imagery suggests favourable-looking outcrops there as well, so we’re pretty excited about that. We now have a lot of strike length that remains to be evaluated on the joint venture with Osisko, as well as drill-ready targets on the CV1 and 2 pegmatites.”

With a $250,000 work commitment for year one, FCI might take precedence over CV1 and 2. Plans will be determined shortly by a committee made up of two reps from each company. Osisko will act as operator on FCI in accordance with a previous ownership agreement.

Gold and base metals possibilities also merit attention. An earlier grab sample from FCI reported by Virginia Mines brought historic, non-43-101 results of 38.1 g/t gold, while another graded 0.3 g/t gold, 150 g/t silver, 1.89% copper, 11.15% lead and 1.45% zinc.

Interestingly, that was the report that tipped off 92 about Corvette’s lithium potential. Not focused on the energy metal, Virginia just briefly noted the presence of pegmatite. Intrigued, 92 made an initial one-day visit in October 2017 “and saw massive spodumene sparkling on this big outcrop,” remembers Smith. Grab samples revealed 0.8%, 3.48% and 7.32% Li2O from the then-unnamed CV1 pegmatite and 1.22% from CV2, which also returned 90 ppm Ta2O5.

Currently helicopter-accessible, the exploration area sits about 15 kilometres south of the all-season Trans-Taiga Road and transmission line.

92’s also been busy with lithium-bearing pegmatite on its Pontax project, roughly 260 crow-flying kilometres southwest of Corvette. A week of work curtailed by last summer’s forest fires brought one grab sample grading 0.94% Li2O and 520 ppm Ta2O5, while another taken 600 metres away showed 0.72% Li2O and 87 ppm Ta2O5. A third sample taken another 1.3 kilometres along strike assayed 631 ppm Ta2O5 and an anomalous 0.02% Li2O.

“The samples come from an area of large outcrops that likely connect. The samples are random and separated by a decent distance, so they’re probably representative,” says Smith. “It’s a very good secondary project that complements Corvette.”

The company holds two other James Bay-region properties hosting pegmatite, Eastmain and Lac du Beryl. Looking at an entirely different energy-related commodity, 92 filed a 43-101 technical report for the Golden frac sand project in southern British Columbia last April. Located adjacent to the Moberly silica mine where Northern Silica restarted operations last year, Golden “hits the criteria for grade, rail and other infrastructure, proximity to markets and commodity demand,” says Smith.

As for Corvette, “I think it has enormous potential. It has a lot of tonnage potential, it’s in a new area, the geology works and the next program could really make the difference. So it’s positioned with a maximum amount of upside. The Osisko deal is very positive too and they’re a good partner to have, so I think 92 is well-positioned to really maximize the value of this asset.”
