Spring Canyon & Mud Springs


Spring Canyon and Mud Springs are Carlin-type gold projects located ~6 km southeast of Carlin, Nevada. The Spring Canyon property position is located immediately north of the mineralized Rain structural corridor and the Mud Springs property is located northeast of the Emigrant Springs deposit.

Pre-mineral compressional faulting (Roberts Mountain Thrust) have juxtaposed western facies siliciclastic rocks on top of eastern facies carbonate rocks.  Anticlinorium formed as a result of the contractional deformation.   Syn- to post-mineral extensional faulting has acted as fluid conduits and/or cuts and offsets mineralization.  The host rocks are composed of both the allochthonous calcareous mudstones and carbonate rocks of the Devonian Woodruff, Mississippian Webb, and Chainman Formations, as well as the eastern facies carbonate rocks.

The alteration is expressed as sulfidation, silicification and local decalcification in the allochthonous upper plate rocks. Alteration appears to be structurally controlled, and may have leaked into the upper plate directly above mineralized lower-plate rocks.

Anomalous pathfinders (As, Sb) have been identified on the project area through reconnaissance rock chip sampling. At nearby deposits, mineralization is strongly controlled by anticlines (Rain) and extensional faults (Emigrant Springs). Mineralization is characterized by gold associated with barite, pyrite, decalcification and silicification hosted in the Webb Formation at the contact with the Devonian Guilmette limestone.

Note: The nearby mines and deposits in the region provide context for EMX's Project, but this is not necessarily indicative that the Project hosts similar mineralization, tonnages or grades.

The Spring Canyon and Mud Springs projects are available for partnership.
