92 Resources advances metallurgy for NWT hard rock lithium

by Greg Klein | June 1, 2017

Phase I mineralogy studies have 92 Resources TSXV:NTY confident that its Hidden Lake lithium project in the Northwest Territories could be amenable to a conventional flowsheet. QEMSCAN and Electron Probe Micro Analysis on a composite sample from each of four pegmatites showed similar results, confirming spodumene as the primary host of lithium. The coarse-grained spodumene shows very good liberation characteristics and low iron content, the company stated.

The 1,659-hectare Hidden Lake project has all-weather
road access to Yellowknife, 45 kilometres southwest.

Spodumene liberation “indicates a strong potential for recovery using dense media separation and flotation techniques, which are common processing methods applied to spodumene-bearing pegmatites,” 92 Resources added.

The program also found potential for tantalum recovery, which will be further assessed in Phase II. About to begin, the program will conduct flotation tests to determine the reagent scheme and assess the ability to produce spodumene concentrate without additional processing.

Last year’s channel sampling targeted four of six known lithium-bearing spodumene dykes, with the best result showing:

  • 1.58% Li2O and 31 ppm Ta2O5 over 8.78 metres

  • (including 1.78% Li2O and 31 ppm Ta2O5 over 6.93 metres)

The company filed a 43-101 technical report on Hidden Lake in January.

92 Resources’ portfolio also includes the 5,536-hectare Pontax lithium prospect in northern Quebec and the 3,211-hectare Golden frac sand project in southeastern British Columbia.

In February the company closed an oversubscribed private placement of $895,199.
