Critical Resources Ltd (ASX:CRR) is a step closer to a maiden JORC-compliant resource, with the latest results from its drilling campaign at the Mavis Lake Lithium Project in Ontario, Canada, intersecting visual spodumene-bearing pegmatite zones.
Multiple spodumene-bearing pegmatite dykes have been intersected totalling 28.25 metres in step out hole MF22-117, including 23.9 metres of spodumene mineralisation from 126.1 metre to 150 metre downhole.
Zones continue at depth
These visual zones illustrate the pegmatites’ geometries and that the zones continue at depth, with the greatest vertical depth drilled to date of around 250 metres, in drill hole MF22-118.
The company has also encountered multiple spodumene-bearing pegmatite dykes extending 14.6 metres in hole MF22-118, including 9.75 metres of spodumene mineralisation from 247.75 metres to 257.5 metres downhole, demonstrating mineralisation at previously unseen depth.
A total of 53 of 59 drill holes have intersected spodumene-bearing pegmatite to date, including most recent holes from MF22-117 to MF22-118.
These visual zones continue to provide support of significant pinching and swelling throughout the pegmatites.
The swell areas can host a significant amount of spodumene laths, as confirmed through visual identification, and provide significant thickness of mineralisation.
Understanding the geometries of the pegmatites will help delineate the mineralised zone as CRR continues to test the continuity east of Pegmatite 6 and towards Pegmatite 18.
The broader strategy
The current 50-metre infill drill-hole spacing will continue to test strike length and down-dip continuity to further delineate the spodumene-bearing pegmatites to underpin the development of a maiden JORC compliant resource.
The company has so far drilled 7,960 metres of the 10,000-metre program. Next on the agenda is testing some 3 kilometres of potential strike length towards Pegmatite 18.
The Mavis Lake Project’s location provides a strategic advantage. It’s just 19 kilometres from the town of Dryden and adjacent to the main rail and road networks connecting directly to Thunder Bay, which is being touted as a proposed regional hub for lithium processing.
The region boasts excellent infrastructure including hydroelectric power, which is located a few kilometres to the south-west of the project.
“Builds further confidence”
CRR chairman Robert Martin said: “To intercept a further cumulative 28.25 metres and 14.6 metres of lithium-bearing pegmatites in the following two holes from one of our largest cumulative intercepts in previously untested areas at Mavis Lake builds further confidence in our program as we work towards delineating our maiden JORC-compliant resource.
“These results show the pegmatites remain open at depth and along a potential strike length of approximately 3 kilometres between our Pegmatite 6 and Pegmatite 18 prospects. We look forward to keeping the market updated as we continue our extended drilling program and when our assay results are received.”
