U.S. Gold Corp. announces CK Gold Project drilling results

Global Mining Review,
U.S. Gold Corp. has received assays for the last three holes of its CK Gold Project 2021 drilling programme. The company continues to be encouraged by the positive results from its confirmatory and expansion drilling. Additionally, in June 2022, internationally acclaimed geologist Dr Richard Sillitoe reviewed the core, consulted with company geologists and conducted a site visit of the project. Following the visit, Dr Sillitoe confirmed that the gold-copper mineralisation is of porphyry type and may have expansion opportunities at depth, to the southeast and in other, yet to be discovered, porphyry intrusions since deposits of this type can occur in clusters.
Kevin Francis, V.P. Exploration and Technical Services of U.S. Gold, said: “The primary purpose of the 2021 drilling programme was to support feasibility study level hydrology and geotechnical studies. The three holes reported, CK21-04c, CK21-05c and CK21-08c, were primarily hydrology holes. CK21-04c confirms results of additional 2021 drilling which intercepted future mineral resource expansion potential immediately south and below the proposed open pit. While we know that there are additional mineral resources requiring further exploration expenditures, our priority is to realise the value of the commercially attractive gold-copper project identified in our pre-feasibility study, published 1 December 2021. We continue to advance the permit to mine application, which will be led by Wyoming's Department of Environmental Quality (DEQ). We were honoured to host D. Sillitoe at the Project. His keen observations and recommendations have resulted in an improved understanding of the project geology and ideas for new discoveries.”
Dr Richard Sillitoe Visit
Dr Sillitoe spent three days with the U.S. Gold geology team reviewing drill core and visiting the project site. He confirmed previous geologic examinations that theorised the project's gold and copper mineralisation was derived from a porphyritic granodiorite intrusion. The porphyritic texture has been partially masked by subsequent tectonism that resulted in a weak gneissic texture and localised mylonitization. Mineralisation is associated with potassic alteration that resulted in the development of biotite and magnetite after magmatic hornblende throughout the granodiorite. A-type veins containing chalcopyrite and molybdenite were identified. These veins show classic textures and lack alteration halos.
Element plots were constructed in plan view which show concentric zones of higher-grade zinc and manganese assays rimming the gold and copper mineralisation and a depleted zinc/manganese core, consistent with a hydrothermal mineralising system of porphyry type.
Samples of porphyritic granodiorite and molybdenite have been collected for analysis to determine the ages of the host rock and the mineralisation.
