Report: Ruby The Ruby has been well-described numerous times, by Knopf (1913), Pardee and Schrader (1933), Roby and others (1960), Foster (1987), and in numerous unpublished studies included in MBMG files. The following description is a compilation of all previous studies. The Ruby was discovered in 1883 and worked until at least 1920. Total value of gold and silver produced was $1.25 million at the time of production. Underground maps show more than 3000 feet of underground workings on several levels. The workings were apparently connected with those of the Columbia to the south. The mine followed a N10W 75NE zone 150 feet wide and 4800 feet long containing vuggy quartz veins and quartz cemented breccia. Wallrock is welded ash-flow tuff of dacitic composition which contains sericite and pyrite as alteration products over a large area. Adularia and quartz are alteration products near the veins. In addition to quartz, the veins contain calcite, pyrite, galena, sphalerite, chalcopyrite, and silver sulfides; all were relatively minor constituents. Within the mineralized zone, base metal sulfides increase and precious metals decrease with depth. The average grade for the 4700 tons of ore produced between 1906 and 1910 was 1.9 oz/ton Au and 34 oz/ton Ag. Foster (1987) speculates that the mineralization was formed in fumaroles that developed with compaction and cooling of the ash. The Memphis adit to the west is a 3000 foot cross cut to the Ruby zone at the 600 foot level. A discharge issues from the portal and it is described separately in this paper. The Ruby workings consist of one locked portal with standing water inside, several open stopes, a caved shaft, and several caved adits. There are no environmental problems present.
