Burner Hills Project
Burner Hills Project
Sage grouse are leks are not uncommon in this part of Nevada but the area surrounding the claims is classified as “General” sage grouse habitat. Other lands in the vicinity are BLM, administered by the Elko District Field office of Tuscarora. Scattered private “ranch” parcels are situated about a mile from the JS claims.
Geology at the Burner Hills is mostly made up of Tertiary volcanic; windows of Ordovician siliceous sediments are present as well. The Elko County map indicates that the most abundant rock units at the Burner Hills are “middle” Tertiary age. Andesites occur as flows and pyroclastic rocks that are deposited on the Paleozoic basement; some intrusive andesite is suspected as well. The county report describes the mineralization, first discovered in 1880, as lead-silver produced from the Mint mine. This mine is situated just one-half mile north of the JS claims and produced high-grade, complex ore containing galena, sphalerite, chalcopyrite, pyrite and arsenopyrite from a quartz vein breccia cutting andesite. The JS claims are located over the Silver Coin (to NE) and Silver Ace (to SW) prospects that occur on a N3540E quartz-filled fissure with 50°SE dip. Dumps contain both andesite and Paleozoic chert fragments that apparently are cut by the mineralized structure. The fault zone is heavily iron-stained and pyrite occurs in bleached dump material. Wallrocks are silicified and gangue locally includes fluorite according to the county report. Sampling by the NBMG indicates that anomalous Hg is present as well.
Exploration has been carried out by numerous companies. Placer Dome is said to have completed holes as deep as 850 feet in 1987 and 1988. Reportedly there are intercepts in their drilling up to 30 feet of 100-500 ppb. The LR2000 reports indicate that many different companies have held claims in the vicinity in the last few decades.
Recommendations: Investigate the extent of the exploration work that has been completed in the area. Determine if reasonable targets are untested. If the ground is available, stake additional claims to the NE and SE to cover possible extensions of the structure mined at the Silver Ace and Silver Coin prospects. Recon sampling to determine if other mineralization is present on the favorable NE striking SE dipping structures. Complete additional dump sampling and examine the material mined to characterize the potential mineralization of interest. Determine if the significant ratios and abundance of precious metals are present to warrant future drilling.
