Why is this small-cap ASX mining stock rocketing?

Investors have been fighting to get hold of the lithium explorer's shares today following the release of exploration drilling results. These are from the 100%-owned Adina Lithium Project in the Eeyou Istchee James Bay region of Quebec, Canada.

According to the release, recent exploration drilling has discovered a new high grade lithium zone 200m southwest of the current Adina Lithium Resource.

The company revealed that results from AD-24-170, drilled to the south-west of Adina Main, have returned an "outstanding" result of 61.5m at 1.62% Li2O. This includes 24.0m at 2.82% Li2O.

Further drilling is now underway around AD-24-170 to explore the scale and orientation of this new pegmatite zone at Adina.

In addition, resource delineation drilling is continuing to provide excellent results in the central portion of the Adina Deposit at the project.

Work is also progressing on an update to the mineral resource estimate (MRE) for Adina, which currently sits at 59Mt at 1.12% Li2O, classified in the inferred category. Its next update is expected to include material in the higher confidence indicated category due to the closer spacing of drill data now available.

Furthermore, the small-cap ASX mining stock advised that the updated MRE will be used in initial project studies for Adina, which will now consider operating scenarios both with and without the repurposing of the Renard Project and associated infrastructure for lithium concentrate production.

'Globally significant'

Winsome's managing director, Chris Evans, was pleased with the discovery. He said:

The discovery of a new zone of high-grade mineralisation 200m outside the current 59Mt Resource at Adina continues to open up the potential scale of Winsome's globally significant lithium deposit in Quebec. In addition, we are also progressing work on an update to the Mineral Resource at Adina this Quarter which will feed directly into our project studies for Adina, including the evaluation of the new Renard processing and infrastructure opportunity. Furthermore, results from infill resource delineation drilling continue to confirm and verify previous drilling results at Adina Main including the presence of thick, high grade, near surface lithium mineralisation.

This small-cap ASX mining stock is now up almost 60% since this time last month.
