Altair Minerals Limited has reported its activities for the June 2026 quarter, highlighting several key developments. The company completed a strategic placement of $28.2 million with Endeavour Gold Corporation, a wholly owned subsidiary of Endeavour Mining plc. Altair also announced a fully funded exploration program at the Greater Oko project, which includes 40,000 meters of diamond drilling and 35,000 meters of reverse circulation drilling. The company appointed Simon Bolster as Technical Advisor and Dr. Sonia Scarselli as Specialist Advisor to the Board, and formed a joint Altair-Endeavour Technical Committee. Altair established three camps at South Oko and two camps at North Peters, with approximately 200 operational personnel in Guyana to support expanded exploration activities. The company reported a strong cash balance of approximately $33.6 million at the end of the quarter. Exploration highlights include the identification of a second coherent major drill target at South Oko, high-grade gold mineralisation at North Peters, and the validation of the W1 Target through auger drilling.

Altair Minerals is optimistic about the potential of the Greater Oko project, with ongoing exploration activities aimed at identifying new mineralisation targets. The company is well-positioned to commence diamond drilling at South Oko and North Peters following the wet season.
