A copper located in the NE¼ sec. 35, T38N, R20E, WM, 2 miles SE of the Billy Goat group of claims. It worked an 80-100' wide mineralized zone in andesite. Development includes a 200' adit, a 50' adit, and several open cuts. it shipped 2 tons of ore in 1914.
Structure: Eightmile Creek Fault Trends N30w. It Starts About 30 Mi To The South And Extends Into British Columbia, Where It Becomes Part Of The Frazer River Fault System. Near Mine Fault Dips Steeply West. Adjacent Rocks Are Commonly Sheared And Brecciated; On East Side Rocks Are Foliated Up To 3 Mi From Fault. Throw On Fault Is Unknown But Must Be Large Based On Opposing Rock Types.
Tectonics: Cascade Volcanic Arc
Deposit: Deposit has been given the informal name of a breccia pipe cu deposit, for which there is no published model. Fracture zone in andesite 80-100 ft wide is mineralized in places at copper glance mine. Additionally, area contains tourmaline-bearing breccia pipes and altered rock 12 unpatented claims and a millsite. ; info.src : 1 pub lit
Development: R.e. Kucera was exploring mineralized areas of andesite of isabella ridge in and near copper glance mine
Geology: Mineralization is in small shears in andesitic tuffs and breccias cut by several plagioclase porphyry dikes. Andesite and basalt flows present locally, particularly in upper part, and rhyolitic or dacitic tuff and breccia are found locally in mafic rocks. Mudflows are also found in this sequence. Thin lenticular beds of sedimentary rocks are interlayered with volcanic rocks. These formed in an island arc setting
Rock formation(s): Andesite Of Isabella Ridge
Ore(s): Fault Intersections
