Structure: Post Mineral Shearing & Faulting
Deposit: The deposit is located at the apex of a thin alluvial fan. Ore consists of veins in a small plug of rhyolite porphyry which has intruded lode was discovered As a result of dry placer operations. Located at the apex of a thin alluvial fan, the gravel of which is gold bearing. Some gold mined in 1917. ; info.src : 1 pub lit; 2 unpub rept; 3 field observ
Deposit type: Low-sulfide Au-quartz vein
Development: Lode was discovered As a result of dry placer operations.. Apparently inactive in 1984.
Geology: Ore consists of veins in a small plug of rhyolite porphyry which has intruded now schistose limerock greenstone. Coarse gold generally occurs embedded in masses of limonite that have resulted from oxidation of arsenopyrite. The hagan lode was one source for the placer deposits in limerick basin.
