Critical’s inaugural drilling at its Mavis Lake lithium project in Ontario is off to a good start with the very first hole intersecting visual spodumene.
Spodumene – a common lithium-bearing mineral – was intersected throughout a pegmatite intercept of 7.63m in the hole, which was completed to a depth of 47m.
The 49-hole program totalling 5,000m is intended by Critical Resources (ASX:CRR) to form the basis for a JORC resource estimate.
Other holes such as MF22-63, MF22-64 and MF22-65 will test lithium grade continuity of Pegmatite 6 as observed from the 2018 drilling.
“To encounter visual mineralisation in our first drill hole at Mavis Lake is extremely exciting,” managing director Alex Biggs said.
“The company has moved quickly and efficiently in the acquisition and exploration strategy for Mavis Lake and it’s great to see results so early in our campaign.
“We feel that Mavis Lake has the potential to be a transformational asset for the company and we are committed in our goal of defining a JORC compliant Resource.”
Hoping for lithium treasures
The first hole, MF22-60, was designed to validate historic drilling from 1979 which intersected mineralisation.
The 7.63m of white to grey pegmatite mineralisation intersected is estimated to contain about 25% of medium to large, white-grey, spodumene crystals.
Drilling has started on MF22-61 which will test the down-dip continuity of lithium mineralisation within the Pegmatite 6 zone.
Mavis Lake pegmatites are found within the correct zonation for lithium enrichment from the Ghost Lake Batholith, a fertile granite intrusion.
A recently completed airborne survey demonstrated the potential continuity of geological trends between Pegmatite 6 and Pegmatite 18.
This potential continuity represents new areas of interest that will be investigated via surface mapping and sampling with the aim of identifying new drill targets
