SnapshotThe fact that the Goldwedge property and mill have been on care and maintenance since 2015 is an indicator of impairment.

In March 2021, the Company completed the acquisition of the Manhattan project located in Nye County, Nevada adjacent and proximal to the Company’s Goldwedge property. This acquisition of 4,300 acres (1740 hectares), combined with the Goldwedge 1,771 acres (717 hectares) gives Scorpio Gold complete land control of 6,071 acres (2457 hectares) around the Goldwedge facility, providing the opportunity to expand surface operations and the potential for expanding underground mining and exploration.

On January 4 2022, the Company announced the final results of its phase I drill program at the Goldwedge property.

On July 22, 2022, the Company received final determination from Nevada Department of Environmental Protection on Water Pollution Control Permit NEV2002107.

Summary:

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.
