Untested Hg bearing fault zone in the Goldbanks District
Located in Nevada
Bonanza grade low sulfidation epithermal veins
The Secret Canyon property is located in the East Range, 50 kilometers (31 miles) south of Winnemucca, NV and 8 kilometers (5 miles) northwest of the Kinross/Premier Goldbanks project, in Pershing County, Nevada.
The Goldbanks district began with the discovery of gold on the east flank of the Goldbanks Hills in 1907. Associated mercury deposits at the Goldbanks Quicksilver Mine were first developed in 1914 and additional mercury mineralization at the nearby Pronto Plata mine near Table Mountain was discovered between 1939-1941. In the 1980's to 1990's, Kennecott Exploration, First Sierra Gold Corporation, and Billiton conducted exploration which centered on prospects in the Table Mountain area and which were identified through initial soil sampling by Kennecott and later refined by Billiton. Several drill holes were completed and at least one short run of low grade gold mineralization was intersected.
The Secret Canyon property is located in southern portion of the Northern Nevada Rift. Renaissance's property is on the northern margin of the Goldbanks district, a large epithermal district with multiple high grade vein zones. Immediately to the southeast of the property Barrick gold controls a high-grade sediment hosted low- sulfidation epithermal vein called the Rye vein. Further to the southeast Kinross controls a large land position with multiple gold bearing low- sulfidation epithermal gold zones mostly hosted along the Tertiary unconformity. Recent work by Kinross has identified a bonanza grade feeder structure to that system with 1.5 meters of 192.5 ppm Au and 10,850 ppm Ag (Ellis and Stroup, 2015). This intercept indicates the district is capable of producing bonanza grades similar to those being mined elsewhere in Nevada at Midas and Fire Creek.
At Secret Canyon gold was discovered by BLEG analyses coming out of a recessive weathering northeast striking structural zone hosted in Paloeozoic siliciclastic rocks. Follow up mapping and sampling identified the source of the gold as a partially eroded low sulfidation epithermal system similar to the Rye vein. Multi-gram gold mineralization occurs in a silicified northwest dipping fault zone juxtaposing Mississippian Inskip formation in the hangingwall and Pensylvanian/Permian Havallah formation in the footwall. The gold bearing portion of the structure does not outcrop well and has not been drill tested.
The mineralized structural corridor continues southwest into a Miocene graben capped by post-mineral basalts. A silica blanket is well developed in Tertiary sediments which crop out below post-mineral basalts providing evidence that the core of the hydrothermal system is preserved to the southwest under post-mineral cover. The target is similar to the Golden Devil target successfully tested by Kinross to the southeast, buthere preserved at a considerably shallower depth. Renaissance is seeking a joint venture partner to test the outcropping gold bearing structural zone as well as its southwest projection into the Tertiary basin. The property is an opportunity to explore a highly prospective epithermal district with a strong land position and a well developed database of geology, geochemistry, and geophysics.
