Grid Metals Corp (TSXV:GRDM) has received high-grade assay results for drill core samples obtained from a 2012 exploration programme on the Lucy claim, part of the company’s wholly-owned Falcon West Lithium Property. The Property is located approximately 120km east of Winnipeg, Manitoba, and 110km south of the company’s Donner Lake Lithium property. The 2012 drill core had not been previously assayed, and the new samples were obtained by Grid staff from William C. Hood, P. Geo., who was the vendor of the property.
The new assays outline an outcropping and relatively flat-lying, highly fractionated spodumene-bearing pegmatite system featuring high grade lithium, cesium, and tantalum values. The area is only a few hundred metres from the Trans-Canada Highway
Key takeaways from the 2012 drill results reported here are:
- High grade lithium values encountered in several holes including 2.1% Li2O over 6.1m (LU-12-02, from 23.5m) and 1.8% Li2O over 12.3m (LU-12-05 from 2.0m)
- High-grade cesium values were also encountered including 10.3% Cs2O over 3.3m (LU-12-02, 25.7m – 29.0m) with a maximum value of 17.2% Cs2O over a core length of 1.1m
- Numerous tantalum-enriched intervals were also identified including 0.09% Ta2O5 over 14.4m (LU-12-05, 3.9m -18.3m), 0.53 Ta2O5 over 2.7m (LU-12-03, 17.14m – 19.83m), 0.04% Ta2O5 over 3.7m (LU-12-13, 21.36m – 25.00m), and 0.04% Ta2O5 over 10.66m (LU-12-14, 24.03m – 34.69m)
- These exceptionally high cesium values and associated high-grade lithium and tantalum values confirm the presence of a highly evolved pegmatite system similar to the world class Tanco pegmatite located ~100 km to the north
- Lithium values in drill results are in line with other known historical drill results
- The pegmatite system is open to the north, west and south and at depth.
- The ArtDon-Lucy Target area has spodumene lithium mineralization noted over a 1.25km strike length with minimal drilling over much of the target area.
- The Company plans to drill the 1.25km trend later this year after completing consultation with affected First Nations in the area
- The Property is wholly-owned with no royalties other than 2% NSR royalties on the purchased claims covering the ArtDon and Lucy pegmatites
Cesium Values
To provide context for the high-grade cesium results being reported, the company notes that cesium is a rare metal classified as a critical metal by both the U.S. and Canadian governments. Its uses include compounds used in drilling fluids, aviation applications and atomic clocks. Globally, there are three principal deposits from which cesium has been commercially mined: the Tanco pegmatite mine in Manitoba; the Bikita pegmatite mine in Zimbabwe; and the Sinclair mine in Australia. In 2019 the Sinclair Mine sold the Tanco Mine 19,000t of pollucite (the primary cesium ore mineral) ore with an average grade of 9.1 % Cs2O for the sum of A$17.4M.
About the Falcon West Property
The Falcon West property is located within the West Hawk Lake Greenstone Belt area of south-eastern Manitoba. Lithium-bearing pegmatites that have been historically known in the area are hosted in mafic volcanic rock units present at the contact between the Wabigoon and Winnipeg River geological Subprovinces. Grid Metals has staked approximately 90km of this prospective mafic volcanic and granitic contact. The initial focus for exploration is the near surface mineralization at the aforementioned 1.25km ADL Target Trend.
The ADL Target Trend comprises the known ArtDon, Lucy South and Lucy North pegmatites. Several phases of drilling have been completed over the decades by numerous companies including Sherritt Gordon (1943, 19 drill holes – no analytical data), East Braintree Lithium Corp (1955, 48 holes for 2,986m – limited analytical data), Tantalum Mining Corporation of Canada Limited (1983, 4 holes 296m – tantalum assays only) and Avalon Ventures (2000 – 10 holes lithium and tantalum assays). The last drill holes were completed in 2012 by William C. Hood P.Geo and were not assayed at the time of drilling but remained securely stored by Mr. Hood, facilitating their re-examination and initial rare metal assays by Grid.
The ADL Target Trend is the first priority for the company’s Falcon West exploration efforts. It is approximately 1250m in length and historic work suggests that the aforementioned pegmatites may be connected and/or form part of a larger system.
“It is rare to see outcropping pegmatites with this high degree of geochemical fractionation – especially so close to major infrastructure,” Vice President Lithium, Carey Galeschuk, said.
“The new Lucy Pegmatite assay results underscore the potential of the ADL trend to develop into a near surface resource and for new discoveries of similar, evolved LCT-type pegmatites along the 90km of the prospective contact zone that we’ve captured in the greater Falcon West property.”
Currently Grid is planning to submit work permits for diamond drilling at the Falcon West Property. Surface mapping and both geochemical and geophysical surveys are also being planned for the upcoming field season.
