Critical Resources Limited (ASX:CRR) (“Critical Resources” or “the Company”) is pleased to advise that following continued drilling success at Mavis Lake, the Company has approved an extension to its current drilling campaign at the Company’s 100 per cent-owned Mavis Lake Lithium Project (“the Project”) in Ontario, Canada.
Highlights
- Outstanding results from Phases 1 and 2 and fast-tracked approvals has allowed for the commencement of phase 3 of the current drilling program at Mavis Lake
- Phase 3 program aims to continue along strike, extending the mineralisation to the east towards known pegmatite outcroppings
- The Phase 3 extension program designed to prove continuity along strike and add scale to a potential resource
- Program extension follows further intercepts of spodumene-bearing pegmatite in the most recent drill holes
The extension will be used to extend the main zone area towards the east. The 10,000m phase 1 and 2 campaigns provided structural data on pegmatite geometries and trends in the main zone. Phase 3 drilling will step out with an increased drill hole spacing of 100m and will continue to target extension towards the east. All drilling from Phases 1, 2 and 3 will contribute towards JORC resource modelling.

Phase 3 drilling was approved after assessing the continued results from Phase 2, where drilling continues to intersect multiple spodumene-bearing pegmatites and strike extension to the east. The abundance of spodumene mineralisation (confirmed through visual assessment) appears to have increased in multiple zones with visual estimates as high as 40% spodumene laths within pegmatite over 6.25m in MF22-1231. Full details on drill holes MF22-122, MF22-123, MF22-124, MF22-125, MF22-126 and MF22-127 can be seen in Appendix 1.

Assay work continues and results will be released as received.
A total of 9,481m of approved drilling has been completed to date, with the Company’s primary focus having been infill drilling and now extension drilling.
Immediate 100m drill-hole spacing will continue to test strike length and down-dip continuity to further delineate the spodumene-bearing pegmatites and underpin the development of a maiden JORC compliant resource.
Critical Resources Chairman Robert Martin commented:
“Having recently been on the ground at Mavis Lake and seeing the results that our in-country geologist, geological consultants and drilling crews are achieving, it was a very easy decision to increase the current program. Having consistently intercepted spodumene-bearing pegmatites and increasing strike length in a previously untested area is an excellent outcome, we believe our phase three program will continue this trend.
We look forward to the phase three drilling program confirming our view that the mineralised zones are continuing to the east, towards an area that has known and mapped pegmatites, providing a potential strike length up to 3km long.
The Company’s confidence in the asset, as we work towards delineating a maiden JORC Compliant Resource, is strong and as such we have began early stage planning and permitting for a Phase Four program.”
