Gold hunters with deep pockets, take note: a Nevada gold mine with a 150-year history has gone on sale with a price tag of $40m.

Bonanza King Mine is a lode gold mine in Nevada’s Humboldt Range, first discovered in 1868 and now on sale via Sierra Sotheby’s International Realty. The 20-acre Pershing County mine has a rich mining history and what looks to be a bounty of gold and silver deposits.

The private Nevada mine comes with physical proof of gold and silver present and studies reveal that its mineral vein has been classified as high grade. It has patented mining claims that carry specific guaranteed entitlements including expansion beyond its boundary lines. The mine closed in 1910 after sulfide ore was encountered and a lack of technology ceased mining activity.

Recent mineral deposit evaluations conducted in the Humboldt mountains by Cornell University geologists suggest trending characteristics to the Comstock Lode discovery – a rich deposit of silver in Nevada that sparked a silver rush in the 19th century. The owner told the agent they panned gold out of each of the nine spots they tried on the surface of the mine.

The Bonanza King Mine is said to be the last of its kind in Northern Nevada, located in the Spring Valley mining district just outside of Lovelock, 100 miles east of Reno. It offers the chance to revive a historic mine and capitalise on its mineral-mining potential and consists of a two-compartment shaft set under mountainous desert landscapes.
