Structure: Foliation Trends E-W. Fracturing And Shearing Trend Nne To Ne

Alteration: Weak Phyllic, Structurally Controlled Propylitic. Breccias Have Been Flooded By Silica

Tectonics: Cascade Volcanic Arc

Deposit: Mineralization seen is high in system and prophyry core, if present, is probably deeply buried. Target zone contains several small breccia pipes. Little disseminated mineralization. Deposit contains a larger proportion of mo than is typical of these deposits but insufficient amount to call it a porphyry molybdenum deposit

Deposit type: Porphyry Cu-Mo

Development: 5 drill holes were not particularly encouraging

Geology: Said to be similar to glacier peak deposit in metallogeny and alteration assemblage

Rock formation(s): Mount Buckindy Pluton;Mount Buckindy Pluton;Tonalite Gneiss Of Bench Lake
