Swift is a Carlin-style gold project along the northwest projection of the Cortez Trend in Nevada. Windows to prospective lower-plate rocks in the Shoshone range have recently been recognized as north to northwest trending anticlinal folds that postdate the Roberts Mountains Thrust. The anticlines served as conduits for mineralizing fluids at the Pipeline and Goldrush deposits located southeast of Swift along the Cortez Trend. The anticline exposed at the Goat Ridge window projects across the EMX land position and toward Elder Creek. Elder Creek contains Carlin-style mineralization hosted in upper plate rocks.
Previous exploration targeted lower-plate rocks beneath Elder Creek, but neglected the 35° eastward post-mineral tilting in the Shoshone Range. Vertical holes drilled from Elder Creek appear to have drilled into a separate fault block before intersecting the Roberts Mountains Formation.
EMX is targeting 1) untested lower-plate rocks down-plunge from the Elder Creek Mine, along the projection of the Goat Ridge window anticline, 2) shallow tests of lower-plate rocks beneath sulfide-bearing alteration in the upper plate near the Mill Creek Window, and 3) mineralization in lower-plate rocks beneath surface alteration and a multi-element geochemical anomaly at Ferris Creek.
Note: The nearby mines and deposits in the region provide context for EMX's Project, which occurs in a similar geologic setting, but this is not necessarily indicative that the project hosts similar mineralization.
