Herecules Project

 Location

The HERC claims are located 43 miles east of Fallon, Nevada and three miles east of Fairview Peak, in the Gold Basin Mining District. Six lode claims are situated near the inferred caldera margin the Fairview Peak caldera.   Elevations range from 5800 to 6400 feet (1768-4950 m) in the prospect area.

 

Target Concept

At the Hercules project, the potential for bulk mineable mineralization hosted in the Tertiary volcanics is to be explored. High-grade veins are potentially present as well and associated with the caldera ring-fracture system at the south end of the claims. The host rocks are Tertiary rhyolites that have historically produced ore in the Fairview and Gold Basin district mines.

 

Previous / Current Activities

Past claims at the Hercules prospect have mostly been by individuals who located a single claim. Larger claim groups have been staked in 2016, by Bell Mountain Exploration, several miles to the south of the Herc claims. Previous exploration, evidenced by larger claim blocks held in the past, have been focused to the west in the Fairview Mining District and south in the Bell Mountain District.

 

Geology

In 1996, the NBMG  (Field Studies Maps 11,12) published a geologic map of the Bell Mountain and Bell Canyon quadrangles that provide details of the distribution of the geologic units in the vicinity of the HERC claims. Mapping focused on unravelling the geologic events related to development of the Fairview Peak caldera. The NBMG summarizes the local geology as follows: ”A complex assemblage of ash-flow tuff, lavas, lava domes, debris deposits, and small intrusions accumulated in and around the Fairview Peak caldera during a brief period between 19.3 and 18.5 Ma . These rocks form four distinct sequences, only three of which are well represented in the Bell Canyon Quadrangle. These are (1) the tuff of Fairview Peak and related megabreccia and debris deposits, (2) the informally named lavas of Bell Canyon and related dikes and pyroclastic deposits, and (3) late intracaldera dikes. Rhyolitic lava domes are abundant in the Bell Mountain Quadrangle but form only a few small outcrops in the southeastern corner of the Bell Canyon Quadrangle. The earliest caldera-related igneous activity was emplacement of porphyritic rhyolite domes and dikes (Tir) in the Fairview district at 19.3 Ma. Rhyolitic pumice in sandstone south of the caldera in the Bell Mountain Quadrangle also gives an age of 19.3 Ma, which suggests that minor rhyolitic activity preceded major ash-flow eruption around much of the caldera.”

 The 1996 mapping is important to the understanding of the geologic history during the Tertiary volcanic activity. Just north of the Hercules prospect is an exposure of older “lava” of Westgate.  These rocks formed an irregular topography upon which the Fairview Peak sequence is deposited. Near the Hercules prospect, the northern margin of the caldera boundary is mapped with a WNW trend. Late intracaldera dikes are present near the HERC claims. 

 

 

Mineralization

Historically, the Fairview and Gold Basin Districts have produced precious metals from high grade ores. Most of the production was achieved in the early 20th century. Mineralization in the districts is characterized as epithermal veins developed in Tertiary volcanic rocks.

In the vicinity of the Herc claims, the NBMG describes epithermal, precious metals mineralization in the district as occurring along WNW vein structures. He notes that mineralization in the Gold Basin District is proximal to the an intracaldera dike such as those mapped near the Hercules prospect.  An older, regional geologic assessment, by Schrader (1941), describes the Hercules prospect as a fault breccia with a mile of strike length. 

 

Work Planned

Geologic mapping is planned to determine the potential along the ring fracture that hosts the historic vein at the Hercules prospect. Systematic sampling is to be carried out to establish the distribution of trace and precious metals at the project. Geophysical surveys may be conducted to gain understanding of the subsurface geology and determine favorable subsurface target zones to be drill-tested in the future.
