Target: Green Monster property contains a "Carlin-type" gold system hosted by Ordovician to Permian sedimentary rocks. Outcrops expose evidence for structural and stratabound controls within a fault-bounded carbonate window surrounded by Tertiary ash flow tuffs.
Location: The Green Monster Project lies on the eastern flank of the Monitor Mountains in northern Nye County, Nevada about 61 miles southwest of Eureka and 58 miles northeast of Tonopah. The property lies in unsurveyed Sections 10, 11, 14, 15, 22, and 23, T10N, R48E, and in unsurveyed Sections 25, 26, 35 and 36, T11N, R48E,.
Ownership: The Green Monster property consists of 92 unpatented mining claims controlled by AuEx. The claims lie within the Toiyabe National Forest about 0.5 miles east of the Table Mountain Wilderness.
History: Early prospecting of Green Monster Canyon probably began at the time that nearby Danville District was established in 1866. Minor antimony production from jasperoid bodies in the central part of the property occurred during the 1900's. Chevron Oil Company -- Minerals Staff conducted exploration for gold in the 1970's that consisted of detailed geologic mapping, rock chip sampling, and ten RC drill holes for a total of 1,160 feet. Dome Mining explored the prospect between 1981 and 1987, but the only data on-file at AuEx is a summary map showing drill collars, alteration, soil gold anomalies, and gold intercepts. Dome drilled approximately 92 RC holes ranging in depth from 100 to 400 feet. Dome also drilled 5 core holes for an aggregate depth of 3226 feet. Twelve of the holes yielded significant gold intercepts.
Geology: The Green Monster prospect lies along a broad north-northeast trending zone of normal faults that define the eastern margin of the Monitor Range. The footwall blocks of several fault strands within the zone form elongate windows that expose altered Paleozoic carbonate and siliciclastic rocks beneath a thick sequence of mid-Tertiary tuffs and flows. The Paleozoic rocks include limestone, dolomite, siltstone, shale, sandstone, and quartzite that comprise a north-northeast-striking anticline, apparently overturned toward the east-southeast. Interpretations presented in the Nevada Bureau of Mines and Geology Bulletin 99A, "The Geology of Northern Nye County, Nevada suggest that the Paleozoic sequence ranges in age from Ordovician to Permian. Several northwest-striking rhyolite dikes intrude the Paleozoic sequence.
Numerous jasperoid bodies occur within a north-northeast-trending corridor 3000 feet wide by 15000 feet long on the Green Monster claim block. The jasperoid bodies are spatially associated with zones of fault breccia and collapse breccia. Analyses of rock chip, soil, and drill samples show that gold is closely associated with silver, arsenic, antimony, mercury, barium, and copper. Several antimony prospects, exposing bodies of stibnite and stibiconite, have yielded multi-ppm gold values in rock chip samples.
