Significant Antimony And Near-Term Production Potential In Historical Leach Pads At Limo Butte

VANCOUVER — NevGold Corp. announced positive, consistent antimony (Sb) and gold (Au) pit sampling results from the historical gold leach pads at its Limousine Butte Project in Nevada. The historical gold leach pads were from mining operations in 1989-1990, which had no focus on antimony in a significantly lower gold price environment at less than US$400/oz of gold. The historical leach pads are an opportunity for potential near-term antimony production. Based on historical records, it is estimated that between 2.4 million to 3.0 million tonnes of previously mined material exists on the leach pads at surface with positive, consistent antimony and gold grades based on NevGold sampling.

Large quantities of previously mined material with significant antimony at surface in historical Crushed and Run of Mine (ROM) gold leach pads are an opportunity for near-term antimony production. Estimated tonnage based on historical records of 1.4 million to 1.7 million tonnes of material, with NevGold pit sampling results averaging 0.27% Sb and 0.34 g/t Au; Crushed leach pad has material size of approximately 3/4 inch. Estimated tonnage based on historical records of 1.0 million to 1.3 million tonnes of material, with NevGold pit sampling results averaging 0.31% Sb and 0.18 g/t Au; ROM pad has variable size material. Antimony and gold grades are very consistent throughout both historical leach pads and all sample pits had significant mineralization. Certain areas of the leach pads have results of 0.74% Sb to 0.81% Sb. There is strong future potential for extracting the remaining gold mineralization in the historical leach pads along with the antimony.

Metallurgical testwork completed by NevGold highlights the strong geometallurgical characteristics of the Project, with antimony leaching the preferred recovery method. 2025 metallurgical testwork showed acid leaching with antimony recoveries up to 92%. Antimony recovery has minimal to no impact on gold recovery; the gold in the historical leach pads could also be recovered in the future after antimony processing is completed. Acid Leaching is being reviewed as the preferred metallurgical process for antimony as there is currently no reliance on downstream processing at third-party smelters or refineries; the acid leaching scenario would produce antimony metal at site through a conventional leaching scenario, which has many similarities to Solvent Extraction-Electrowinning (SX/EW) used for oxide copper in the copper industry.

Historical leach pads provide opportunity for near-term antimony production. The larger commercial gold-antimony opportunity can be advanced and developed in parallel to the historical leach pad opportunity, including drilling, metallurgical testwork, and the preparation of a Mineral Resource Estimate (MRE) at Resurrection Ridge (including high-grade antimony Bullet Zone discovery made in 2025) and Cadillac Valley. A staged project development approach offers various potential development scenarios over the next 12-24 months which may achieve near-term production and cash flow.
