Location: Esmeralda Co., T4S, R40E, Railroad Springs Mining District
At Clayton Ridge precious metal mineralization occurs in epithermal quartz veins and stockwork veining hosted by bleached argillized limonite stained, and moderate to strongly silicified Cambrian sediments, cut by Tertiary andesitic dikes. Northeast and northwest trending as well as low angle thrust fault controlled brecciated quartz veins converge at a north-south trending ridge with intense stockwork quartz + limonite veining and strong silicification.Here, a small resource of 8000 ounces Au was delineated by Billiton Minerals in 1990.A total of 17 rock chip samples were collected by the author and taken to Chemex Labs for fire assay Au, Ag plus 32 element analysis.
Historical mining activity consists of two shallow shafts, one short adit, and numerous prospect pits. The property is not part of any organized mining district and no production has come out of the area. In 1982 Felmont Oil drilled 22 rotary holes (CL-through CL-22) for an unspecified total footage. These holes were broadly spaced with only two of the holes drilled into the ridge with the small resource. In 1990 Billton Minerals USA, Inc. mapped, grid sampled, trench sampled, and drilled 19 reverse circulation holes (CR-1 through CR-19) in two phases for an unknown total footage. They delineated a small resource of about 8000 ounces Au on the northern end of a highly altered and stockwork veined ridge. Significant intercepts include:
10’ of .062 opt Au @ 20’ in hole CR-10
5’ of .03 opt Au @ 10’ @ 10’ and 10’ of .116 opt Au @ 35’ in hole CR-2
25’ of .02 opt Au @ 35’ (includes 10’ of .128 opt Au) in hole CR-16
The property is underlain by Cambrian calcareous siltstones, limestones, and quartzites cut by Tertiary rhyolite – andesite dikes emplaced along northeast and northwest faults. Alteration ranges from weak argillic to moderate – strong silicification, coupled with intense stockwork quartz and stockwork limonite + quartz veining. Northwest and northeast trending brecciated quartz veins and low angle thrust controlled jasperoids are evident on the property and converge at the northern end of a highly stockwork quartz + limonite veined and silicified ridge that is approximately 600’ x 2000’ in length.Highly anomalous and ore grade gold values coupled with anomalous Ag, As, Sb, Hg, and Cu are associated with this area. Reportedly, gold values in the jasperoid and stockworked siltstone ran up to .72 opt Au. A total of 17 rock chip samples (27785 – 27800 & 308764) were collected and taken to Chemex Labs for fire assay Au, Ag plus 32 element analysis.
Alteration, stockwork veining, quartz veining, and gold – silver mineralization on the Clayton Ridge property appears to be fairly widespread. The best-looking area on the property appears to be well tested by Billiton drilling (19 holes). However, a closer look with emphasis on detailed geologic mapping and additional sampling might further define additional potential on the Clayton Ridge property which contains areas of anomalous gold mineralization out there by itself, away from organized mining districts. The area appears to have significant potential.
