Vault Enters In To Agreement For Option To Acquire Portfolio Of US Historical Mining Assets And Corresponding Historical Databases R. Nick Horsley, Chief Executive Officer of Vault states "The acquisition of these four projects benefits from extensive historic exploration, including sampling, drilling, mapping, feasibility studies, and resource estimations that document established mineralization across the properties. The depth of this work provides immediate value and establishes a strong foundation for rediscovery. $KNOX.V 🇨🇦 $KNXFF 🇺🇸 $M85 🇩🇪 - Mia Silver Historical Mining Project (Idaho) US Bureau of Mines Sampling notes up to 178 ounce per ton silver and 1.1 ounce per ton gold - Wheeler Tungsten Historical Mining Project (Nevada) Historical Feasibility level Study Historical Production & Historical Resource - Robinson Dyke Historical Mining Project (Idaho) Historical Production & Historical Resource - Golden Dome Historical Mining Project (California) Historical Resource drilled by Hecla See important disclaimers about historical work (Non NI 43-101) and read the entire press release here: juniorminingnetwork.com/junior-miner-n… New website coming soon!

Nevada has a long but often overlooked history as a strategic U.S. tungsten producer, with roots dating back to the late 1800s when tungsten was first identified alongside gold and silver systems. Its importance surged during both World Wars, particularly in the 1940s, when tungsten became essential for hardened steel and military applications. Government-backed programs accelerated development across multiple districts, positioning Nevada as a meaningful domestic supplier at a critical time. Following WWII, production declined as global supply increased and lower-cost sources, particularly from overseas, entered the market. Many Nevada operations were ultimately shut down, leaving behind a network of historical mines and underexplored districts. Today, that legacy is becoming increasingly relevant again. With tungsten classified as a critical mineral and global supply chains heavily concentrated, Nevada’s historical deposits represent compelling brownfield opportunities. Modern exploration techniques, combined with a renewed focus on domestic resource security, are driving fresh interest in these past-producing regions. Tungsten’s role in defense, aerospace, and advanced manufacturing continues to grow, and Nevada’s history suggests it may once again have a role to play in securing North American supply.

Vault Strategic’s Wheeler Tungsten Project has roots and major development that trace back prior to the 1950s. Following the discovery of tungsten in 1950, the project advanced rapidly under a Defence Minerals Exploration Administration (DMEA) contract, with Mt. Wheeler Mines, Inc. actively developing the deposit between 1952 and 1955. The project also benefited from historical work and drilling by Anaconda, one of the most prominent mining companies of its time, further validating the scale and significance of the system. A clear reflection of tungsten’s long-standing role as a critical defense metal. Historic significance. Strategic relevance.
