Big Blue is a porphyry Cu-Au-Ag prospect located in Elko County, Nevada, approximately 75 kilometers (“km”) southeast of the city of Elko, NV. The project area includes the past producing Delker Mine, which produced 94,434 pounds of copper at an average grade of 6.2% Cu between 1916-1917 ¹ and shares its southern boundary with Reyna Silver’s Medicine Springs Ag-Pb-Zn Carbonate Replacement (“CRD”) project.

Outcropping garnet skarn with high-grade Cu ± Au-Ag rock chip samples collected by Ridgeline occurs on the Project on two outcropping buttes surrounded by post-mineral gravels covering a roughly five (5) km target area zoning towards Medicine Springs. The primary target at Big Blue is porphyry-skarn Cu ± Au-Ag mineralization, which may also be the source of CRD mineralization at Medicine Springs – analogous to the Butte Valley porphyry Cu-Au system inferred to be a source of CRD mineralization at the Company’s Selena project. The 100% owned Project is comprised of a total of 41 square kilometers of highly prospective exploration ground that has seen limited exploration since the early 1900’s and will benefit from the Ridgeline teams systematic approach to discovery.
