Solis Minerals Limited has commenced diamond drilling at its 100%-owned Cinto Copper Project in southern Peru, targeting potential copper porphyry mineralisation across an initial program of approximately five holes or 2,500 metres.

The maiden campaign follows the grant of drilling permits in December 2025 and subsequent community information requests by the Ministry of Energy and Mines. Drilling will test coincident geochemical and geophysical targets, including three key areas identified from a recent induced polarisation survey and surface sample results reaching up to 8.7% copper. Eleven drill pads have been permitted to provide operational flexibility as the program advances.

“We have commenced diamond drilling at Cinto following the successful mobilisation of our team and equipment to site. The project area has excellent copper porphyry potential with abundant outcropping breccia-style copper mineralisation, geophysical targets, proximity to globally significant copper mines and regional infrastructure.”

— Mitch Thomas, Chief Executive Officer

Solis is advancing the Peruvian copper campaign in parallel with ongoing diamond drilling at its Mandacaru Lithium Project in Minas Gerais, Brazil. The company expects to deliver further operational updates on Mandacaru, including laboratory assay results, during September 2026.

“We look forward to providing drilling updates as the program advances alongside the progress we are making at the Mandacaru Lithium Project in Brazil.”

— Mitch Thomas, Chief Executive Officer

Chief Executive Officer Mitch Thomas noted that the company looks forward to providing ongoing updates as field activities progress at both operations.
