16, 2022, the Company entered into a mineral lease agreement with BMR for exploration and mining rights on 261 unpatented lode mining claims that comprise the Stockade Mountain Project situated in Malheur County, Oregon. In November 2024, the Company located an additional 77 unpatented lode mining claims which brings the total area of the property to approximately 10.5 mi2(27.22 km2).

The property is located approximately 50 miles (80 kilometers) southeast of Burns, Oregon and 90 miles (145 kilometers) southwest of Boise, Idaho in a rural area used for ranching and farming. The high-grade gold/silver Grassy Mountain Gold project, which is currently undergoing permitting for an underground mine and adjacent milling operation, is located in Malheur County about 40 miles (64 kilometers) northeast of Stockade Mountain. The nearby community of Burns, Oregon is a commercial center for ranching and farming and can supply the necessary accommodation, food, fuels, supplies, and some of the contractors and workforce for exploration and development.

Historical data generated within the project demonstrates the discovery potential for significant high-grade gold/silver mineralization that may be amenable to underground mining. 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 gold/silver
