The selvages of the veins are clay-altered but not significantly more than the surrounding bedrock. Most sulphides are weathered and pyrite boxworks, malachite and rare yellow cerrusite together with limonite and hematite are more common. The quartz is coarse grained, locally laminated and carries disseminated pyrite, pyrrhotite, chalcopyrite together with rare galena, tetrahedrite and amorphous black sulphides. The mineralization located to date consists of quartz veins up to 20 cm wide in the few exposed areas and reportedly up to 2.0 m in the Cambridge Mine workings.
The quartz monzonite is cut by north to north-northwest trending, apparently steeply-dipping faults or shears which host the gold mineralization. The Cambridge Camp is underlain by Cretaceous quartz monzonite overthrust by Tertiary andesite in the northwestern corner of the Project. The two companies formed a joint-venture to consolidate and explore the Camp in 2020. Silver Range staked the Price Lode workings west of the Cambridge Mine in 2016 and explored the target as the Enigma Property with prospecting, sampling and geophysical surveys Auburn Gold Mining LLC staked the Cambridge Mine in 2019. There is no record of recent major company activity in the Camp. Ernest Rink, the mill foreman, took over the mine and staked a number of properties in the area including the Price Lode, explored briefly in the 1960's. from 1940 to 1942, closing when all gold mining was shut down by order of the Federal Government. The operation shut down in the late 1800's and was briefly reactivated by the Cambridge Mining Corp. Approximately 10,000 tons of ore grading approximately 0.3 OPT Au was extracted during this period and processed at a nearby mill on the Walker River. Development at that time consisted of a shaft sunk to 250' and a comparative amount of drifting on two levels. In 1878, Henry Blasdel, Nevada's first state governor, purchased the Cambridge Mine and operated the property for about ten years. Gold in the Camp was first discovered near the Cambridge Mine in the 1860's. The Cambridge Mine, together with these two other projects are the principal gold occurrences in the Wilson Mining District. It is also 8 km northeast of the Rockland Mine, recently optioned by Evergold Corp. The property is 9 km east-northeast of the Pine Grove Project, a development stage joint-venture between Lincoln Gold Mining Inc.
The consolidated Cambridge Property is located 33 km south of Yerington in Lyon County, NV in the Wilson Mining District. Both companies jointly own a block of 15 intervening claims. Auburn holds 15 Federal Lode Claims ("claims") covering the Cambridge Mine and Silver Range holds 21 claims covering the nearby Enigma Property centered on the Price Lode showing. Silver Range has entered into a joint venture with Auburn Gold Mining, LLC ("Auburn") of Sacramento, California to consolidate their respective claim holdings in the area of the historic Cambridge Mine and to explore the combined claim holdings (the "Project") in a coordinated manner. (TSXV:SNG) ("Silver Range" or the "Company") is pleased to announce that it has consolidated the historic Cambridge Mining Camp (the "Camp") in the Walker Lane, western Nevada.
