Last Chance Mine

The story

In 1885, prospectors struck a rich lead and silver vein in the narrow canyon above Wardner, naming it the Last Chance Mine. For twenty-five years, it was one of the Silver Valley’s most aggressive producers—and one of its most bitterly contested properties, locked in subterranean claim disputes with its giant neighbor, the Bunker Hill & Sullivan Mining Company. Before Bunker Hill swallowed Last Chance whole in a 1910 stock deal, this canyon was a violent labor battleground. In April 1899, union miners protesting non-union wage undercutting and company spies hijacked a train from Burke, packed it with dynamite, and detonated Bunker Hill's nearby concentrator mill right down the slope.

You won’t find standing headframes or decaying wooden ruins sitting out in the open here. Decades of heavy metal extraction left vast quantities of toxic tailings across the canyon, prompting massive environmental remediation. Under the Bunker Hill Superfund program, historic surface structures were dismantled and the underground workings were permanently sealed and flooded to contain heavy-metal drainage.

What looms at the end of Wardner’s Main Street is an engineered earthwork: a massive, smoothed-over capped tailings mound sitting right where public pavement terminates against the gulch. Millions of tons of silver and lead waste lie buried beneath that contoured grass cap. Standing at the end of the asphalt looking up, you're staring at the literal burial cap of the mine that ignited Idaho's industrial labor wars.
