NevGold Mobilizes Drill To Test Historical Leach Pads To Advance The Near-Term Antimony Production Scenario at Limo Butte Vancouver, British Columbia, March 12, 2026 (GLOBE NEWSWIRE) -- NevGold Corp. (“NevGold” or the “Company”) (TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce that the permits have been received and a drill rig is mobilizing to its Limousine Butte Project (the “Project”, “Limo Butte”) in Nevada. The drilling will test the historical gold heap leach pads for antimony with the objective of advancing the leach pads to a near-term antimony production scenario. This is one of the only near-term, at-surface antimony production scenarios in the United States with a path to potential antimony metal production by 2027. NevGold CEO, Brandon Bonifacio, comments: “There are very few opportunities like the near-term antimony production potential from the historical gold leach pads at Limo Butte. There is a clear mandate in the United States to find near-term production from a number of Critical Minerals, and we have one of those opportunities which we are rapidly advancing. We are in an advantageous position as we have oxide antimony at surface amendable to leaching at a brownfield mine site in the State of Nevada, which is one of the top mining jurisdictions globally with a systematic permitting regime and strong community support. Our focus is to drill the leach pads to advance to a Mineral Resource Estimate by the beginning of Q2-2026, which will define the grade and quantities of contained antimony that we have on the pads. Once an MRE is delivered, we will be able to evaluate the various development scenarios to extract the antimony from the leach pads, with the objective of reaching antimony metal production by 2027. We have the opportunity to be one of the near-term solutions to the United States building a fully vertically integrated antimony supply chain” Key Highlights Drilling will advance the leach pads to a Mineral Resource Estimate (“MRE”) by the beginning of Q2-2026 building on the Phase 1 sampling completed (see News Release from January 6, 2026): The MRE is a key step in defining the quantities of antimony that could be processed in the near-term from the historical gold leach padsDrilling will be completed over the coming weeksCertain areas of the leach pads had Phase I sampling results of 0.74% Sb to 0.81% Sb (See Figure 1) Metallurgical testwork completed by NevGold highlights the strong geometallurgical characteristics of the Project, with acid leaching the preferred recovery method for antimony: 2025 testwork using acid leaching resulted in antimony recoveries of up to 92%Acid Leaching is being reviewed as the preferred metallurgical process for antimony as there is no reliance on downstream processing at third-party smelters; 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 industryAntimony 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 Antimony is one of the highest priority Critical Minerals due to its strategic importance and military applications; Limo Butte is a brownfield mine site located in the State of Nevada with near-surface, high-grade antimony mineralization Historical leach pads provide opportunity for near-term antimony productionA larger commercial gold-antimony opportunity could 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 ValleyA staged project development approach offers various potential development scenarios over the next 12-24 months which may achieve near-term production and cash flow 30 holes completed in the current 2025-2026 drill program with 12 holes pending release Limo Butte Planned 2026 Activities / Status UpdateNevGold will continue its active exploration program at Limo Butte including: Evaluating the historical geological database with focus on gold and antimony (completed); Advancing metallurgical testwork (ongoing); Continuing to drill test gold-antimony targets (5,000 meters (30 drillholes) completed, a further 20,000 meters is planned in 2026 focused on the Bullet Zone and Armory Fault discoveries); Advancing the Crushed and Run of Mine (“ROM”) leach pads to near-term antimony production (Drilling March-2026, MRE beginning of Q2-2026, ongoing metallurgical testwork); Completing initial gold-antimony Mineral Resource Estimate (MRE) (in progress).
