Pantoro Gold (ASX:PNR), a gold producer operating in Western Australia, has released a positive update for investors with new drilling results from its OK Underground Mine at the 100%-owned Norseman Gold Project. The announcement, dated July 30, 2025, focuses on ongoing infill and extensional drilling, which is designed to expand the known gold mineralisation at the O2 and Star of Erin lodes.
The company is currently using four full-time underground diamond drill rigs across its three active underground mines at Norseman. The latest results are particularly encouraging, as they confirm the continuity of the O2 ore body both at depth and along its length.
Here are some of the key highlights from the drilling results reported:
- 5.94 metres at 34.47 g/t from 102.8 metres, including a very high-grade section of 0.3 metres at 209.68 g/t.
- 5.69 metres at 75.99 g/t from 174.31 metres, which included an exceptional grade of 0.31 metres at 969.81 g/t.
- 6.3 metres at 10.11 g/t from 200.2 metres, an intercept that sits approximately 160 metres below the current development in that area.
The company notes that the high-grade mineralisation also continues beneath the existing Star of Erin Mineral Resource. Managing Director Paul Cmrlec commented on the results, stating:
“These results confirm ongoing continuity of mineralisation at depth in the OK Underground Mine ore system. With drilling to be ongoing at the mine for the foreseeable future, Pantoro Gold is confident that the OK Underground Mine will provide a baseload of high-grade mill feed long into the future.”.
This news aligns with Pantoro’s growth strategy, announced in June 2024, to expand its underground operations and scale up production at Norseman from an initial 100,000 ounces per year to over 200,000 ounces annually. The company’s active drilling program, which is expected to total 250,000 metres in FY2026, and the untapped potential of the Norseman project, position Pantoro for substantial growth.
