Target: Carlin-type target defined by a 4 km long jasperoid zone developed in upper Cambrian carbonates which dips under shallow alluvial cover into large regional fault zone.
Status: In earn-in agreement with Hochschild Mining plc
Location: The Mars property is located in the northern Groom Range, approximately 5 miles south of the town of Rachel in Lincoln County, Nevada.
History: The project was first identified in the 1980’s on a helicopter reconnaissance program for Carlin-type projects carried out by Exxon minerals. Three drill programs were completed targeting the outcropping gold bearing jasperoids in the late 1980’s and early 1990s, with multiple low-grade gold intercepts and only one hole exceeding 200 feet in depth. Renaissance acquired the project in 2018 and completed a new geologic map, a small soil survey, and a ground gravity survey. In late 2018, the property was optioned to Hochschild who funded additional surface geochemistry and an IP survey and drilling.
Geology: The Mars project covers > 4 km of jasperoids with elevated Au + As + Sb occurring along multiple stratigraphic horizons from middle Cambrian to lower Ordovician. The highest-grade surface occurrences (up to 3.7 g/t Au in rocks) are in the south jasperoid area where silicified Cambrian Lincoln Peak formation dips gently northeast under argillized Tertiary volcanic rocks. Renaissance mapping and gravity data have defined a complex set of NE offset by NW structures on the east side of the property which may be feeding this zone of mineralization. A second zone of extensive jasperoids with elevated As and Sb occurs on the north side of the project in the uppermost Cambrian stratigraphy. The Cambro-Ordovician unconformity is likely faulted out in surface exposures and is an untested high priority target for karst-controlled mineralization similar to the mineralization discovered by AuEx at Long Canyon.
