Pioneer Lithium discovers three pegmatite outcrops at Root Lake project

Pioneer Lithium (ASX: PLN) has made a positive beginning to its maiden exploration program identifying new outcropping pegmatites at Root Lake in northern Ontario, one of its three battery metals projects in Canada (reports Small Caps).

This comes just a week after the company reported that field teams were already on the ground carrying out mapping and sampling, aiming to identify outcrops along two highly prospective corridors.

The outcrops were discovered within the Extended Morrison Corridor, in the northwest portion of Root Lake.

They are along strike from the Morrison-McCombe pegmatite system being explored by Green Technology Metals (ASX:GT1).

The company says the outcrops mapped by the field team at Root Lake are interpreted to be open in multiple directions.

They were concealed beneath thick overburden and dense vegetation.

The outcrops were observed over a 3km strike length, with those identified so far being up to 4 metres wide and are exposed over lengths of up to 10m.

Chief executive officer Clinton Booth said the thick overburden had limited the team’s prospecting and mapping activities.

“The discovery of multiple pegmatites at Extended Morrison confirms our initial expectations of the potential for the continuation of the Morrison-McCombe pegmatite system,” he added.

Field teams will continue over the coming weeks to test the Central Corridor in the southeast section of Root Lake, adjacent to another Green Technology Metals pegmatite spodumene system, Root Bay.

Root Bay has an inferred resource of 8.1 million tonnes at 1.32% lithium oxide.

Pioneer listed last month after its $5 million initial public offering closed with what the company described as significant oversubscriptions.

Root Lake (owned 90%) consists of 94 claims totalling 1,927 hectare and is located in northwest Ontario.

It straddles the Sydney Lake-Lake St. Joseph Fault, an east-west trending, steeply dipping brittle-ductile shear zone that defines the boundary between the Uchi and English River sub-provinces.

Several S-Type, peraluminous granitic plutons hosting lithium and other rare-metal mineralised pegmatites have been discovered in proximity to the Sydney Lake-Lake St. Joseph Fault, and within 5km of the Root Lake project.
