Vancouver, British Columbia, April 02, 2026 (GLOBE NEWSWIRE) — NevGold Corp. (\u201cNevGold<\/strong>\u201d or the \u201cCompany<\/strong>\u201d) (<\/strong>TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50<\/strong>) is pleased to announce further metallurgical testwork results on the residual tailings material from the positive Phase II antimony (\u201cAntimony\u201d, \u201cSb\u201d) testwork included in the November 5, 2025 News Release.<\/u><\/em><\/a> The residual tailings material from the antimony leaching process had remaining gold mineralization, and went through a second sequential stage of leaching testwork focused on gold. The positive sequential antimony and gold leaching results highlight the exceptional geo-metallurgical characteristics<\/u><\/strong> of the oxide antimony-gold<\/strong> Limousine Butte Project (the \u201cProject\u201d, \u201cLimo Butte\u201d) in Nevada, one of the world\u2019s prolific mining jurisdictions. As the Company has stated in previous News Releases, and has now confirmed with testwork results<\/strong>, the antimony recovery process with conventional leaching methods has minimal to no impact on gold recoveries.<\/strong>\u00a0 <\/u><\/p>\n The Company is also pleased to announce the identification of additional antimony mineralization at surface<\/strong> in the historical pre-strip waste dump situated adjacent to the past-producing Golden Butte pit (see Figure 1, 2, 3). Phase I sampling has been completed with assays pending. The identified antimony mineralization in the pre-strip waste dump is another potential source of at-surface antimony material at the Project<\/strong>.\u00a0<\/p>\n NevGold CEO, Brandon Bonifacio, comments: <\/strong>\u201cThe results from our Phase II antimony and gold metallurgical testwork shows that <\/em>leaching in sequence on antimony and gold works favorably as we have envisioned and guided to over the past 12 months<\/em><\/strong>. This is a <\/em>key step<\/em><\/strong> in optimizing the metallurgical flowsheet to recover antimony and gold at Limo Butte. Since we have oxide antimony-gold mineralization, with <\/em>two distinct, separate mineralizing events that initially deposited gold and then antimony<\/em><\/strong>, we are able to achieve <\/em>high recoveries on both minerals<\/em><\/strong> with a simple, sequential leaching flowsheet. Most global antimony projects are sulphide and produce an antimony concentrate, which adds significant complexities to the operation, cost structure, recovery of minerals, and concentrate marketing.\u00a0We are fortunate that Limo Butte has a <\/em>large, near-surface footprint of\u00a0oxide antimony-gold mineralization which is amenable to leaching<\/em><\/strong>, and we have the opportunity to\u00a0<\/em>produce both antimony and gold metal at the project site<\/em><\/strong>. Limo Butte continues to <\/em>distinguish itself <\/em><\/strong>from other antimony projects globally with its<\/em> unique geo-metallurgical characteristics and simple, leach processing flowsheet<\/em><\/strong>.\u201d<\/em><\/p>\n Bonifacio continues<\/strong>: \u201cIt is also encouraging that we have identified another <\/em>potential source of at-surface antimony<\/em><\/strong> in the historical pre-strip waste dump from the past-producing gold mine which did not have a focus on antimony. This would be <\/em>additional antimony material at surface further to the historical leach pads<\/em><\/strong>. We have also completed the drill program on the historical leach pads, and the Mineral Resource Estimate (\u201cMRE\u201d) is on track for Q2-2026.\u201d<\/em><\/p>\n Key Highlights <\/u><\/strong><\/p>\n Limo Butte Planned 2026 Activities \/ Status Update<\/u><\/strong> Summary of Antimony and Gold Metallurgical Testwork Program <\/u><\/strong> Composite samples of 20-kilogram were sent to the Kappes, Cassiday & Associates laboratory (KCA) in Reno, Nevada, for initial antimony recovery metallurgical test work. The core samples were composed of material from the Resurrection Ridge and Cadilac Valley target areas ranging from 64 meters to 377 meters deep. The surface outcrop sample was taken from several outcrops in the historically mined Golden Butte pit, and the nearby Nevada Antimony Mine prospect. Both the surface and core samples contained antimony oxide with minor antimony sulphide minerals. Head assays for the composite samples are summarized in Table 1.<\/p>\n Following the leach testing for antimony, the residual tailings were utilized for cyanide shake tests for gold extraction. Cyanide shake tests were conducted using portions of the pulverized tails material. These test results provide indications of cyanide soluble metal extractions from pulverized material.<\/p>\n\n

The antimony-gold zones at Limousine Butte are typically associated with silicification and the formation of jasperoid breccias within the Pilot Shale unit, which is the primary host rock for Carlin-type gold-antimony mineralization in the area.<\/p>\n
