Other/historical names associated with this locality:
Denny Mine; Denny Antimony Mine


An antimony prospect located about 300' above the Cle Elum River, at the base of Goat Mountain. It worked a 6" vein in breccia along the fault contact between Swauk Sediments and Serpentine. It featured a 178' adit and 3 open cuts.

Tectonics: Cascade Volcanic Arc

Deposit: Quartz vein and 4-12 in. Mineralized fracture occur in addition to the lateritic mineralization. Attitude is variable

Deposit type: Lateritic Ni

Geology: Laterite lies between swauk formation and ingalls complex and thus formed sometime prior to deposition of swauk formation

Rock formation(s): Ingalls Tectonic Complex
Swauk Formation


Ore(s): Weathering Regime
