U.S. Gold Corp. 2018 Drilling

2018 drilling comprised of fifteen holes, totalling 25,310 feet (7,714 m), and was conducted in two phases. Phase 1 provided "scout" drill tests within several broad new target areas and was limited due to permitting constraints. Phase 2 began in early November (upon approval of the district-wide Environmental Assessment and Plan of Operations) providing a first test to several drill targets in areas previously inaccessible due to permitting limitations. All of the holes encountered moderate to thick intervals of anomalous gold with moderate to locally very strong associated pathfinder metals. Many of these also intersected significant gold assay intervals (see 2018 drill table below). Nine of the fifteen holes intersected lower-plate rock units; five of these holes penetrated the permissive host Wenban Formation. Eight holes encountered variably altered permissive upper-plate Comus calcareous siltstone. The total prospective host unit thicknesses at Keystone are several thousand feet. Carlin-style zones of alteration with containing gold and pathfinders are very widespread and present in all locations drilled to date. Drilling at Keystone continues to show all of the right ingredients are present for big, Carlin-type, gold deposits. Seeing strong anomalous gold in the latest drill holes only strengthens that theory. Finding the right structure and feeder zones that would host these styles of big deposits is now the focus of our 2019 program

Historical Drilling

Historic drilling at Keystone was comprised of about 240 holes, drilled to an average depth of about 300 feet. Past operators of the project include; Newmont, Chevron, USMX, Placer Dome and McEwen Mining Co. However, the Keystone area land positions were fragmented with multiple owners and acquisitions were problematical, inhibiting district-wide exploration programs. Keystone's geology and prospectivity were poorly understood and certainly under-appreciated, i.e. no Pipeline, Cortez Hills, Goldrush, etc. reference. Prior drilling consisted of typical 1980's drilling - conventional and RC drilling looking for shallow oxide, gold mineralization. Nevertheless, high grade and thick intercepts of gold have been encountered as follows:
