Critical Resources Ltd (ASX:CRR) has fast-tracked phase two of its inaugural diamond drilling program at the Mavis Lake Lithium Project in Ontario, Canada, to include a further 5,000 metres of drilling.
The objective of the phase two drilling is to test the continuity between pegmatite 6 and pegmatite 18, with a potential strike length of 1.8 kilometres.
What's more, the drilling will focus on high-priority targets identified through geophysical interpretation, aiming to define a maiden mineral resource at Mavis Lake
“Cornerstone project”
Critical managing director Alex Biggs said: “The combination of strong drill results and newly identified geophysical targets puts the company in a clear position to continue drilling at the Mavis Lake Lithium Project.
"Mavis Lake is quickly becoming a cornerstone project for the company as demonstrated by the consistent drill results we have seen in the first 5,000-metre campaign.
“Our strategy is to define a JORC compliant resource which requires both infill and extensional drilling along strike.”
Phase one drilling results
In total, 37 holes were drilled during the phase one program for a total of 5,000 metres, testing pegmatite 6 at greater depths than was initially anticipated.
The phase one program intersected spodumene-bearing pegmatites in 35 of 37 holes including:
- 18.1 metres of ~20% spodumene in MF22-64;
- 23.1 metres of ~32% spodumene in MF22-72;
- 17.5 metres of ~18% spodumene in MF22-73;
- 15 metres of ~20% spodumene in MF22-85; and
- 14.75 metres of ~16% spodumene in MF22-96.
Phase two rationale
CRR received positive litho-structural interpretation from the geophysical airborne survey flown across the Mavis Lake property in late 2021.
The interpretation is based on magnetic, radiometric and VLF electromagnetic data and has provided a significant basis for the potential of a further 28 new drill targets.
Exploration on these targets has been undertaken to develop a drilling strategy to expand on the inaugural 5,000-metre program.
