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