The Goldwedge property occurs in west-central Nevada where a series of Tertiary volcanic calderas have cut through a basement complex of lower Paleozoic sedimentary rocks. Gold deposits related to these calderas include the giant Round Mountain Mine (some 10 miles north of Goldwedge), as well as the Northumberland Mine of Newmont Mining Corp. While most of the mineralization at the Round Mountain Mine has been mined from Tertiary volcanic rocks, there is good mineralization in the underlying Gold Hill Formation, which is also a host of mineralization at Goldwedge.

Goldwedge occurs near the southwestern margin of the Manhattan caldera, and all known mineralization to date is hosted by a series of lower Paleozoic sedimentary rocks just outside the caldera boundary. The Caldera is believed to have provided significant structural preparation for the gold mineralization at Goldwedge, and age dating suggests that the mineralization is post-caldera. The deposit is hosted by the Ordovician Zanzibar Formation and the Cambrian Gold Hill Formation, where cut by a series of north-northwest -striking fractures and faults, especially the Reliance shear zone. This shear zone is closely associated with the good grade mineralization defined to date.

Mineralization consists of altered sedimentary host cut by complex anastomosing narrow shear zones with a combination of free gold and disseminated gold in the matrix of the rock. The substantial component of free gold allows for simple gravity recovery of a portion of the gold mineralization. The mineralization contains some very high grade intercepts, with the certain core portions of the mineralization grading in the 6.86 to 34.29 g/t (0.20 to 1.0 oz/ton) range.

All final modifications to the Goldwedge mill and gravity circuit were completed in December 2014, resulting in optimized gold recovery and the facility is now being used to batch mill high grade gold material from the Mineral Ridge operation as it becomes available.
