92 Resources Corp. (TSXV:NTY) reported results from the recently completed 2017 field program at its Hidden lake lithium project located in the Northwest Territories. The property is situated within the central parts of the Yellowknife lithium pegmatite belt along Highway 4, approximately 40 kilometers east of Yellowknife.
As quoted in the press release:
Program highlights include:
- Eight channel samples from the HL6 pegmatite assaying more than 1.00% Li2O, to a peak of 2.57% Li2O
- Significant grades of tantalum discovered in the HL8 pegmatite
- 1 m channel grading 162 ppm Ta2O5, to a peak of 233 ppm Ta2O5
- The discovery of a new lithium bearing pegmatite – HL13
The 8 day field program focused on the evaluation of new targets in close proximity to the D12, HL1, HL3, and HL4 pegmatites, where up to 3.31% Li2O has been sampled in prior programs. This work included mapping and channel sampling of the HL6 and HL8 pegmatite bodies, which were discovered at the end of the 2016 field season with grab samples up to 1.86% Li2O (see news release dated November 28th, 2016).
The HL6 pegmatite returned the highest lithium grades during the 2017 program, with up to 2.57% Li2O sampled, and remains a strong target for drill testing along with the D12, HL1, HL3, and HL4 pegmatites (Table 1).
Although less lithium was sampled from the HL8 pegmatite compared to HL6, the HL8 pegmatite returned signification grades of tantalum up to 233 ppm Ta2O5, with a 5.1 m channel grading 162 ppm Ta2O5 (Table 2). Spodumene bearing pegmatites are often zoned with distinct zones of lithium and tantalum, as well as zones which overlap. 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.
The Company is also pleased to report the discovery of a new lithium-bearing pegmatite on the Property (HL13) with 0.48% Li2O returned from initial sampling. This new pegmatite is relatively large with an approximate length of 200 m and shares a similar trend and character as that of HL1, HL3, HL4, and D12. The discovery highlights the potential for additional pegmatites to exist on the Property, with the total number of lithium-bearing pegmatites discovered at Hidden Lake now seven
Samples were analyzed by Activation Laboratories in Kamloops, B.C., by their sodium peroxide fusion ICP-OES+ICP-MS Ultratrace 7 package. Any samples with lithium values that exceeded detection limit were subsequently analyzed by the sodium peroxide fusion ICP-OES lithium ore analysis package.The tantalum values determined by ICP-OES+ICP-MS and may require confirmation by XRF.
The Company is in the process of planning an early 2018 drill program where the overarching objective will be to delineate sufficient tonnage/grade to support an initial mineral resource estimate for the Project. A portion of the program is expected to be funded through the $140,000 grant awarded under the Northwest Territories Mining Incentive Program
