Panthera Resources PLC (AIM:PAT) said the Reverse Circulation/Air Core (RC/AC) drilling programme at the Bassala project in Mali has started.
The 5,000-metre campaign consists of 57 AC holes and 21 RC holes and will test Bassala North, Central and South prospects.
Results from the drilling are expected during the third quarter, said AIM-traded Panthera.
A drilling programme in July 2021 confirmed significant mineralisation in the licence, while a follow-up drilling programme in December 2021 confirmed further mineralised zones in the north of the licence.
Deeper RC drilling in priority areas is now underway.
