10297 GOLD CROWN RD, WONDER VALLEY, CA 92277

This is a once-in-a-generation acquisition opportunity. The Supply-Nightingale Mine sits on 123 acres of fully patented lode mining claims in the Old Dale Mining District, one of the most historically significant gold producing regions in Southern California. The property operated continuously from the 1890s through 1942, when the United States government forced its closure under the War Measures Act. It was not closed because the gold ran out. It was closed because the country was at war.

At the time of closure the mine was still actively producing ore at the 1,250-foot level with gold grades ranging from 0.44 to 0.68 ounces per ton, numbers that would be compelling at any point in history. At today's gold price of nearly $5,000 per ounce they are extraordinary. When this property was last professionally explored in the late 1980s, gold traded at approximately $400 per ounce. The economics of this asset have been completely transformed by the gold market alone without a single shovel of new work.

The Supply-Nightingale Vein is traceable for over 6,000 feet along strike. At least nine parallel mineral veins have been identified on the property. Ore grade material was confirmed from the 600-foot level down to the 1,250-foot level where the mine was still producing at closure. A comprehensive geological report package including original drilling results, vein mapping, longitudinal sections, and surface maps is available to qualified buyers under NDA. An updated independent geological summary report is currently being prepared.

Beyond mining, this property offers compelling alternative development potential. Temperatures exceed 105°F at depth in winter months: a strong indicator of geothermal energy potential that has never been explored or monetized. The property commands unobstructed panoramic views of Joshua Tree National Park, making it a natural candidate for boutique resort, glamping, eco-hotel, or outdoor event venue development in one of the most in-demand desert destinations in the American West. San Bernardino County has indicated openness to a variety of uses for the right buyer and vision.

The seller is motivated, transparent, and highly flexible on transaction structure. All-cash, seller financing, property trade, production royalty, joint venture, and lease-with-option arrangements will all be considered.

This is not a property that requires a single buyer with a single vision — it is a rare, versatile, and historically significant asset waiting for the right operator, investor, or developer to unlock its full potential.
