 28, 2024, the Company executed an amendment to the mineral lease and option agreement with BMR eliminating the requirement of 2,000 meters of drilling by May 16, 2024.

BMR will retain a 2.0% net smelter return royalty on claims owned by BMR and 0.25% net smelter return royalty on third-party claims acquired within the area of influence around the property. Payments to BMR totaling $10,000,000 in any combination of pre-production payments, production or minimum royalties will reduce the production royalties on wholly owned claims by 50% to 1.0%.

Geology

Stockade Mountain exhibits a classic large gold- and silver-bearing low-sulfidation “hot springs” hydrothermal system associated with rhyolite intrusion and doming that formed along a major NW-trending structural corridor.

Gold/silver and high-level mercury mineralization at Stockade is associated with widespread silicification and argillization in a near-surface paleo-hot springs environment. This hydrothermal alteration and mineralization formed in and around rhyolite domes that have intruded gently dipping felsic tuffs. Erosion into the hydrothermal system has been minimal, resulting in the local exposure of probable hydrothermal craters and vents that indicate the paleosurface at the time of hot springs activity. Gold and silver, along with associated elements arsenic, antimony, and mercury, are all strongly anomalous at the surface, however, historical drilling shows that gold and silver values, and their extent, increase significantly with depth below the paleosurface. This is a common characteristic of high-grade gold/silver deposits in similar geological environments, including the previously mentioned nearby Grassy Mountain deposit in Oregon, the Midas, Sleeper, Hollister, National, and Fire Creek mines in Nevada, and numerous analogous deposits elsewhere in the world. The hypothesized economic gold/silver veins at Stockade Mountain would have formed within the vertical zone of vigorous boiling of the hydrothermal fluids, and this is interpreted to have occurred approximately 600 to 1200 feet (183 to 366 meters) below the surface.

Exploration programs conducted by BHP, Phelps Dodge and Placer Dome in the 1980s and 90s included shallow exploration holes that were drilled for bulk tonnage, open-pit potential, with no efforts to target deeper high-grade gold/silver vein deposits. Many of these short drill holes returned significant lengths of strongly anomalous gold mineral
