Green Technology Metals Limited (ASX: GT1) has made a new discovery at its flagship Seymour Lithium Project in Ontario, Canada.
The new discovery, Blue Bear, is located approximately 500m south-east of the Aubry Complex, on the Pye West Limb, and sits within the same current mine permitting and baseline study boundary.
“This is the first discovery at Seymour in over 50 years. To find a spodumene-bearing pegmatite under cover utilising classic geological and modern geophysical and geochemical techniques is testament to the abilities of the GT1 technical team and our exploration modelling,” CEO, Luke Cox, said.
“We will now drive hard to rapidly delineate the scale of this new discovery, as well as testing further new targets in this area of North Seymour. This is expected to culminate in an updated Mineral Resource estimate for the Seymour Project in coming months. We also continue to rapidly progress Preliminary Economic Assessment work on a development of Seymour, with scheduled completion in Q1 2023.”
Blue Bear: New discovery on Pye West Limb
The new discovery, Blue Bear, is located on a Priority 1 target zone delineated during target generation and followed up by diamond drill hole, GTDD-22-0186. During drill site preparation the dozer cleared an access track and pad for the diamond rig, exposing a small one square metre area of bedrock beneath a thin layer of glacial till. The bedrock was quickly identified as spodumene-bearing pegmatite and subsequently confirmed by the Bruker–Raman Spectrometer.
Further mechanical stripping of the area has delineated a pegmatite surface exposure with similar size, geometry and orientation to the North Aubry deposit located approximately 500m northwest. As such, there also exists potential for the two deposits to be associated, including potentially connected at depth, forming a larger mineralising system which we also plan to promptly test with step-out drilling.
Delineation drilling in progress
Delineation diamond drilling has commenced at Blue Bear starting with shallow scissor holes to determine strike and dip of the LCT pegmatite. Initial indications are showing the pegmatite is striking NNW with an apparent dip direction of ENE, dipping 10-30 degrees.
Of the 14 holes drilled to date, all have intersected pegmatite and 12 have intersected significant pegmatite intercepts. Assays have been returned to date for six holes.
Hole GTDD-22-0186 was the first/discovery hole, drilled in an easterly direction from the pad where the initial outcrop was uncovered, and returning 7.1m of weathered pegmatite. Two holes, GTDD-22-0359/0360, stepped out slightly to the north-east and were drilled in a broadly westerly direction against the interpreted dip, returning thick pegmatite intervals of 14.1m at 0.66% Li2O from 20.4m (including 8.7m at 0.95% Li2O) and 14.4m at 1.30% Li2O from 21.1m (including 10.8m at 1.72% Li2O), respectively.
A similar directional hole, GTDD-22-0350, was drilled approximately 60m SSE of the discovery hole and returned a 13.9m pegmatite interval at 1.53% Li2O from 13.8m (including 8.8m at 2.27% Li2O).
Ongoing step-out drilling is set to rapidly delineate the lateral extent of the pegmatite down dip and along strike.
