Lithium B1-B2 Pegmatite

The historic B1 pegmatite was tested to assess the width and extent of observed high-grade spodumene mineralization exposed at surface. Drilling included a down dip hole to assess the vertical extent of the spodumene and the dimensions and attitude of the B1 pegmatite. Drilling combined with field observations have definitively concluded that both B1 and B2 are from a single pegmatite dyke with a strike length of greater than 325m. The drill program identified and provided preliminary dimensions for a high-grade zone of lithium mineralization at the B1 pegmatite. The vertical extent of high-grade lithium appears to be restricted to the upper portions of the B1 dyke exposed in outcrop at the drilled locations.

FM23-01A was drilled down plunge and intersected pegmatite to a depth of 41.3 metres. An intersection of a 3.35 metre zone of spodumene mineralization between surface and 3.35m assayed 1.26% Li2O. FM23-01 was drilled from north to south just north of the B1 exposure to undercut the surface exposure of high grade spodumene mineralization and intersected 20 m of pegmatite between 6 and 26 m. Spodumene was not observed in the core. No other significant Li2O assays were obtained from drill holes testing the B1 pegmatite in this campaign. The east end of the B1 pegmatite is marked by a trenched exposure of high-grade spodumene bearing granitic pegmatite originally referred to as the B2 pegmatite. FM23-06 was drilled at -45o to test the pegmatite beneath the trench and intersected a 4.4 m intercept of spodumene-bearing pegmatite between 32.88 and 37.3 m. The maximum lithium assay was 0.61% Li2O. FM23-07 was drilled at -60o to undercut hole FM23-06 and intersected a wider 10 m zone of pegmatite from 54.42-64.45 m but with lower lithium contents. The maximum Li2O assay from
