Report: The Mogullian Mine consists of a single adit and waste rock dump on a steep hillside. The waste rock is comprise of altered and unaltered yellow quartz rock with iron-oxides present. Only trace amounts of pyrite were observed. The caved adit is discharging onto the dump; there is no evidence of discharge at the base of the dump. Soils do not indicate impact by the waste rock or by the adit discharge. There is no surface water for several hundred feet down hill of the mine site. Tailings were observed is several places below the mine. These deposits were dry and away from any surface water. Impact to soils was limited to the tailings. JMOS10M: Located at the adit discharge point. The sample will be analyzed for Dissolved Metals only. Discharge will be measured by means of a pipe-dam, bucket and stopwatch. A sample site was staked on the South Boulder River to assess impacts to mines visited earlier and to determine impacts from the large tailings pile immediately north of the town of Mammoth. JBSBS10L: Located upstream of first bridge (0.4 miles) below Mammoth. The sample will be analyzed for Dissolved Metals and Total Recoverable Metals. Stream flow will be measured by means of a flow meter. Mogullian On strike with the operational Nicholson Mine just to the east, the Mogullian examines 2 west-trending shear zones that include quartz-pyrite-galena veins up to 2.6 feet thick (O'Neill and others, 1983). However, unlike the Nicholson, gold values are low, with 16 samples having negligible gold , 0.9-2.4 oz/ton silver, and minor lead and zinc. Five hundred eighty feet of workings are apparently present behind a caved portal. The mine discharges water into a dump composed of mainly gray to yellow clays with low metal values (see map). About 1,000 tons of dump material is present.
