Bunker Hill Mine and Smelting Complex

Bunker Hill Mine and Smelting Complex is a major mining and processing facility in Kellogg, Idaho that extracted silver, lead, and zinc from raw ore. The site consists of extensive underground tunnels, processing buildings, and smelting operations for refining extracted metals.

The complex began in 1885 when Phillip O'Rourke filed the initial mining claim and grew into the world's largest smelting operation during its peak years. It became the industrial heart of the Silver Valley region for generations.

The mining complex shaped the identity of Kellogg and surrounding communities by attracting thousands of workers who built their lives here. This working-class heritage remains visible in local traditions and how residents connect to the region's industrial past.

The site is monitored by environmental authorities and subject to ongoing cleanup efforts due to past mining operations. Visitors should be aware that some areas may have restricted access and various safety guidelines apply.

The facility processed more than 35 different metal types throughout its operating history and developed specialized refining techniques for complex ores. This capability made it a globally recognized center for metal processing expertise.
