A former Cu-Zn-Ag-Au mine located near Yucca.
A small belt of stratified rock within a predominantly granitic terrane. A possible volcanogenic massive sulfide deposit that was extensively remobilized during deformation. Hosted in a screen of muscovite schist between two-mica granite and porphyritic granite. Schist in this area is intruded by many small granite dikes and sills.
A stratabound exhalative deposit with a blanket-shaped orebody. Ore controls were strata massive sulfide occurrence n submarine volcanic and volcaniclastic rocks. Host rock unit is the Methow gneiss. Alteration is hydrothermally altered footwall zones (chloritic core, sericitic outer zones). Related structure involves two periods of folding, the latest of which is characterized by isoclinal folding by passive slip deformaton. Tectonic environment: Back-arc extensional cratonic basin.
