Vancouver, British Columbia, Feb. 27, 2025 (GLOBE NEWSWIRE) -- NevGold Corp. (“NevGold” or the “Company”) (TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce that it has discovered significant gold-antimony (“Antimony”, “Sb”) historical drill results at its Limousine Butte Project (the “Project”, “Limo Butte”) in Nevada. Leveraging a robust historical geological database, the Company continues to unlock the substantial gold-antimony potential of the Project, highlighting its promising prospects for further exploration and development in one of the world’s prolific mining jurisdictions.

Key Highlights

• Positive, near-surface, gold-antimony historical drillholes completed by Newmont Corporation (“Newmont”, NYSE:NEM) include:

LIM-40: 4.07 g/t AuEq* over 54.9 meters (1.20 g/t Au and 0.64% Sb), including 6.60 g/t AuEq* over 12.2 meters (2.12 g/t Au and +1% Sb)

LIM-45: 3.02 g/t AuEq* over 36.6 meters (1.23 g/t Au and 0.40% Sb), including 4.83 g/t AuEq* over 12.2 meters (0.35 g/t Au and +1% Sb)

LIM-48: 2.61 g/t AuEq* over 61.0 meters (0.77 g/t Au and 0.41% Sb), including 3.82 g/t AuEq* over 24.4 meters (0.37 g/t Au and 0.77% Sb)

*Gold equivalents (“AuEq”) are based on assumed metals prices of US$2,000/oz of gold and US$35,000 per tonne of antimony (~30% discount to current spot prices), and assumed metals recoveries of 85% for gold and 70% for antimony.

• Significant antimony (Sb) upside: historical drilling had an upper detection limit of 1% Sb but many drill intervals exceeded the limit

• Historical small-scale antimony mining at the Nevada Antimony Mine and Lage Antimony Prospect has been identified at Limo Butte (see Limousine Butte Geology & Antimony Potential Section below)

• Extensive gold-antimony mineralization: multiple zones, including Resurrection Ridge and Cadillac Valley, demonstrate significant potential across a large, open mineralized footprint

All areas at the Project with gold-antimony potential are permitted and ready to drill under the Limo Butte Plan of Operations (“PoO”) approved in November-2024 (see NevGold News Release from November 27, 2024)

• Antimony (Sb) is identified as an important “Critical Mineral” in the United States essential for national security, clean energy, and technology applications, yet no domestically mined supply currently exists

• NevGold will continue re-evaluating historical drilling from the Project, focusing on both oxide gold and antimony; there is only a small amount of historical drilling analyzed for antimony, and large portions of the existing database were not analyzed for antimony creating a significant opportunity to re-assay historical drilling

• More results will be released shortly from the Limo Butte Gold-Antimony Project

Limo Butte Planned 2025 Activities / Status Update

NevGold will continue its active exploration program at Limo Butte including:

• Evaluate the historical geological database with specific focus on gold and antimony (in progress);

• Re-analyze historical drilling with focus on gold and antimony (in progress);

• Drill test gold-antimony targets (subject to the results of the evaluation).

NevGold CEO, Brandon Bonifacio, comments: “The discovery of significant gold-antimony drill results in historical drillholes is an important, emerging development at our Limo Butte oxide gold-antimony project. Limo Butte exhibits significant gold potential, and we have now uncovered an important additional value layer at the Project with the antimony. The higher grade oxide gold targets at Resurrection Ridge and Cadillac Valley coincide with the best antimony results, creating a compelling dual-commodity opportunity. We are well-positioned with a robust historical database containing unreleased gold-antimony results, significant potential to re-analyze historical drilling not previously tested for gold and antimony, and the Project is fully permitted and drill-ready for future exploration and drilling programs. The timing and market conditions are opportune to re-awaken the gold-antimony potential at Limo Butte.”

Limo Butte Geology & Antimony Potential

A review of historical geochemical and drilling data at the Limousine Butte Project has identified multiple areas with strong gold-antimony potential. These zones correlate closely with outcrops of the Devonian Pilot Shale, the primary host rock for Carlin-type gold mineralization in the area. High-grade gold at Limousine Butte is typically associated with silicification and the formation of jasperoid breccias within the Pilot Shale, alteration features also observed in the high-grade antimony results.

Through the data review, the Company uncovered reports detailing two small-scale mining operations at the Nevada Antimony Mine and Lage Antimony Prospect within the Limo Butte Project boundary (see Figure 3 and Figure 4 below). The Nevada Antimony Mine featured two prospect pits that extracted stibnite from a hydrothermal breccia. The Lage Antimony Prospect reported historical unverified sampling results with up to 14.46% Antimony (Sb) with additional prospect pits extracting antimony. The Nevada Bureau of Mines and Geology (“NBMG”) had historical reports on both of these which can be found here: Nevada Antimony Mine Report Lage Antimony Prospect Report

NevGold VP Exploration, Greg French, comments: “After further review of the historical data at Limo Butte, we continue to be encouraged by the footprint and gold-antimony grade in historical drilling completed at the Project. Only a portion of the historical drilling was assayed for antimony, and the results that we have identified are positive for both gold and antimony. It is also promising to see the correlation between the gold and antimony grade at the Project. To get a better picture of the antimony levels we will be reviewing a program of re-assaying some of the historical core and Reverse Circulation (RC) holes. We will continue to focus our future exploration to understand the controls and determine the extent of the antimony mineralization.”

Importance of Antimony

Antimony is considered a “Critical Mineral” by the United States based on the U.S. Geological Survey’s 2022 list (U.S.G.S. (2022)). “Critical Minerals” are metals and non-metals essential to the economy and national security. Antimony is utilized in all manners of military applications, including the manufacturing of armor piercing bullets, night vision goggles, infrared sensors, precision optics, laser sighting, explosive formulations, hardened lead for bullets and shrapnel, ammunition primers, tracer ammunition, nuclear weapons and production, tritium production, flares, military clothing, and communication equipment. Other uses include technology (semi-conductors, circuit boards, electric switches, fluorescent lighting, high quality clear glass and lithium-ion batteries) and clean-energy storage.

Globally, approximately 90% of the world’s current antimony supply is produced by China, Russia, and Tajikistan. Beginning on September 15, 2024, China, which is responsible for nearly half of all global mined antimony output and dominates global refinement and processing, announced that it will restrict antimony exports. In December-2024, China explicitly restricted antimony exports to the United States citing its dual military and civilian uses, which further exacerbated global supply chain concerns. (Lv, A. and Munroe, T. (2024)) The U.S. Department of Defense (“DOD”) has designated antimony as a “Critical Mineral” due to its importance in national security, and governments are now prioritizing domestic production to mitigate supply chain disruptions. Projects exploring antimony sources in North America play a key role in addressing these challenges.

Perpetua Resources Corp. (“Perpetua”, NASDAQ:PPTA, TSX:PPTA) has the most advanced domestic gold-antimony project in the United States. Perpetua’s project, known as Stibnite, is located in Idaho approximately 130 km northeast of NevGold’s Nutmeg Mountain and Zeus projects. Positive advancements at Stibnite including the technical development and permitting has led to US$75 million in Department of Defense (“DOD”) awards, and over $1.8 billion in indicative financing from the Export Import Bank of the United States (“US EXIM”) (see Perpetua Resources News Release from April 8, 2024) (Perpetua Resources. (2025))
