Laeuna Mine; Launa Mine
A silver mine near the crest of the south spur of Mineral Hill. It worked a 7' wide quartz vein in granodiorite. Development includes a 50' shaft, 75' shaft, 60' adit and a 70' crosscut. Several carloads of ore were shipped to San Francisco prior to 1890.
Structure: The Conconully Pluton Is A Directionless, Post-Tectonic Pluton That Was Intruded Into A Major Structural Zone (Stoffel, K.L., Dger, 1990, Oral Commun.).
Deposit: High-grade parts of the vein contained 200-800 oz/ton ag.
Geology: The vein is in the conconully pluton, which is a leucocratic, equigranular to porphyritic, medium-to coarse-grained, biotite- and hornblende-bearing granodiorite to quartz monzonite of cretaceous age (stoffel, 1990).
Ore(s): The 7-Ft-Thick Quartz Vein In Granodiorite Strikes N55e And Is Vertical (Moen, 1973).
