8-K: U.S. Gold Corp. Updates Pre-Feasibility Study for CK Gold Project, Outlines Robust Economics

U.S. Gold Corp. releases an updated Technical Report Summary detailing a pre-feasibility study for the CK Gold Project, highlighting positive economic outcomes and mineral reserve estimates.

Summary

• U.S. Gold Corp. has completed an updated pre-feasibility study (PFS) for its CK Gold Project, summarized in a Technical Report Summary (TRS) effective February 10, 2025.
• The project, located in Laramie County, Wyoming, encompasses approximately 1,120 acres of mineral leases and an option agreement for an additional 712 acres.
• The updated mineral resource estimate includes data from the 2021 drilling program, enhancing resource classification and expanding the modeled mineralized domain.
• The mineral resources are reported using a gold-equivalent (AuEq) cut-off grade, averaging 0.010 oz/st AuEq, and are constrained within an optimized pit shell.
• The Mineral Reserve estimate is based on an open pit mine design and production schedule, with metal prices of $1,755/oz gold, $3.77/lb copper, and $23/oz silver.
• The Mineral Reserves are reported above a value per ton cut-off threshold of $0.01/st.
• The CK Gold Project is planned as an open pit mine with a production life of approximately 10.3 years, processing 20,000 stpd of gold/copper sulfide ore.
• The processing facility will produce a concentrate at 17.0% Cu or greater, with an average gold grade of 41 g/st.
• The project will utilize dry stack tailings to maximize water conservation and structural strength.
• An after-tax, discounted cash flow model, assuming 100% equity funding and a 5% discount rate, indicates a positive economic outcome with a gold price of $2,100/oz and a copper price of $4.10/lb.
• The after-tax NPV at a 5% discount rate is $355.9 million, and the IRR is 29.5%.

Sentiment

Score: 7

Explanation: The document presents a positive economic outlook for the CK Gold Project, with robust economics and a clear path forward. The project has secured key permits and is moving towards feasibility. However, there are also risks and uncertainties associated with the project, such as metal price fluctuations and potential environmental impacts.

Positives

• The CK Gold Project demonstrates a very low waste to ore ratio.
• The project benefits from the absence of a large pre-strip period to expose mineralization.
• The project utilizes simple low-cost mineral extraction methods.
• The project is in close proximity to key infrastructure and support services.
• The project has a life of mine cash cost per equivalent gold ounce of $922/oz, indicating robust project economics.
• The project may be less sensitive to cyclical swings in the prices of either individual metal due to revenue split between gold and copper sales.
• There are opportunities to bolster revenue through the sale of waste rock as aggregate.

Negatives

• The estimates of Mineral Resources may be materially affected if mining, metallurgical, or infrastructure factors change from those currently anticipated at the CK Gold Project.
• Estimates of Inferred Mineral Resources have significant geological uncertainty, and it should not be assumed that all or any part of an Inferred mineral resource will be converted to the Measured or Indicated categories.
• Mineral Resources that are not Mineral Reserves do not meet the threshold for reserve modifying factors, such as estimated economic viability, that would allow for conversion to Mineral Reserves.

Risks

• Metal prices may not continue to support adequate revenues to cover the cost of mining and processing.
• Consumer items, manpower, energy, water, and capital equipment costs could increase, jeopardizing profitable operations.
• The contained metal in the resource may have been misestimated, and the metallurgical performance may not be fully representative of the whole rock mass.
• There is a risk of access to the volume of water required until the well field testing is completed.
• Neighboring residents and landowners could have concerns about real or perceived negative environmental impacts.
• Timelines for receiving water permits from the Wyoming Department of Environmental Quality could be longer than expected.
• Changes in regulations could affect project design and permitting.

Future Outlook

The project demonstrates positive economic outcomes at higher metal prices, and the sensitivity analysis indicates robustness even at reduced metal prices.

Industry Context

The announcement relates to the mining industry, specifically gold and copper projects. The project's location near infrastructure and population centers is a positive factor. The use of dry stack tailings aligns with modern environmental practices in the mining industry.

Comparison to Industry Standards

• The document does not provide enough information to make a detailed comparison to industry standards.
• A full comparison would require a detailed analysis of the project's costs, recoveries, and other factors against those of comparable projects.
• Comparable companies and projects would need to be identified based on factors such as deposit type, location, and scale of operation.

Stakeholder Impact

• The project will provide employment opportunities for local residents.
• The project will generate tax revenue for the state of Wyoming and Laramie County.
• The project may have environmental impacts on the surrounding area, which will be mitigated through the implementation of environmental management plans.
• The project may affect local landowners and communities, and U.S. Gold is committed to engaging with these stakeholders to address their concerns.

Next Steps

• A feasibility study should be commenced to advance project engineering and planning.
• Plans for an EPCM strategy, construction, and operations to support project development should be created.
• A detailed owners team for development, contracting strategy and transitional plan to operations should be identified.
• The mine should be re-designed using possibly 35 ft or 40 ft bench heights.
• Additional variability testing, together with larger scale work on lower grade samples, would be useful.
• Specialty test work with the vendors of tailings and concentrate filtration, including the oxide and sulfide components should be performed.
• Specific test work on the mixed ore zone should be performed.
• Additional vendor specific test work on flotation and regrinding is needed to quantify possible recovery and/or grade improvements utilizing different flotation and grinding technologies.
• Additional discrete studies should be pursued to develop possible capital and operating improvements.
• Activities needed to obtain the required state and local permits should continue.
• Project information should continue to be disclosed and local stakeholders consulted, especially focusing on project impact assessment, local project benefits, and impact mitigation measures.
• A wildlife mitigation agreement with the Wyoming Game and Fish Department should be concluded.
• The needed land use agreements with the Office of State Lands and Investments and the affected private landowner should be concluded.
• A potential alternative backup water supply source should be identified and secured.
• Engagement with the City of Cheyenne regarding the potential post-mining conversion of the pit to a water storage reservoir serving the city should continue.
• A Project Environmental Management System (EMS) consisting of site-specific plans and procedures governing the environmental management of project activities causing potential environmental impacts during construction, operations, closure, and post-closure should be developed and implemented.
