Report: Moonlight The Moonlight is an unusual mine in that it was first worked for production of metallic minerals, then later (after World War II) it produced 5,000 tons of phosphate ore (Popoff, 1965). Gold, silver, copper, and lead were sought from iron and copper-stained quartz-cemented quartzite fault breccia. A select sample of this ore contained .012 oz/ton Au, 7.76 oz/ton Ag, 0.15% Cu, 0.47% Pb, and 0.44% Zn. A map included by Popoff (1965) indicates that the fault zone is parallel to bedding with a N25W 50NE attitude. A phosphate bed forms the hanging wall. Dump material is almost entirely quartzite. More than 3000 feet of workings are present behind a locked portal. Several cabins in good condition are still standing near the mine. All land is on Deerlodge National Forest.
