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.
