A Northwest Territories lithium project gets its first-ever metallurgical studies as 92 Resources TSXV:NTY announced a two-phase program on March 28. The 1,659-hectare Hidden Lake property underwent channel sampling last year on four of six known lithium-bearing spodumene dykes, with the best intercept 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 met program’s first phase examines the property’s spodumene and waste materials, leading to a mineral processing phase intended to separate the two and produce a high-grade concentrate.
Material from four pegmatites will be evaluated separately and, if no significant differences are found, a single composite will undergo processing tests. Those tests would include grinding, heavy liquid separation, magnetic separation and flotation. Plans then call for a preliminary flowsheet and a small amount of potentially marketable spodumene concentrate.
The program will also evaluate potential tantalum recovery.
Hidden Lake has all-weather road access to Yellowknife, 45 kilometres southwest. Carrying out the tests will be SGS Canada, which has considerable experience in spodumene pegmatite processing, 92 Resources stated.
In northern Quebec, 92 Resources has initial lithium exploration planned for Pontax, a 5,536-hectare property in a district known for spodumene-bearing pegmatites as well as gold potential.
Earlier this month the company expanded its Golden frac sand project from 807 hectares to 3,211 hectares. The southeastern British Columbia property sits adjacent to the Moberly silica sand project, now being redeveloped into a frac sand operation and among the assets sought by Northern Silica in its takeover bid for Heemskirk Consolidated.
Late last month 92 Resources closed an oversubscribed private placement of $895,199.
