U.S.GoldMining Inc. Selects Ausenco to Deliver Initial Economic Assessment
AtWhistler Gold-Copper Project, Alaska
PEAto incorporate updated 2024 drilling and evaluate standalone open-pit operation
Anchorage,Alaska – June 9, 2025 – U.S. GoldMining Inc. (NASDAQ: USGO) (“U.S. GoldMining” or the “Company”) is pleased to announce it has selected Ausenco Engineering Canada ULC (“Ausenco”) as the principal consulting firm to lead its proposed initial assessment study (“PEA”) for the Whistler Gold-Copper Project (“Whistler” or the “Project”), located 105 miles northwest of Anchorage, Alaska. The study, as previously announced April 15, 2025, is intended to constitute an initial assessment under U.S. Regulation S-K 1300 (“S-K 1300”) and a preliminary economic assessment under Canadian National Instrument 43-101 (“NI 43-101”).
Highlights:
| ● | The<br> PEA is intended to explore and outline a development opportunity at the Whistler Project<br> for a stand-alone open pit mine and concentrator facility located approximately 100 miles<br> northwest of Anchorage in south-central Alaska, a region which has significant existing and<br> ongoing infrastructure development. |
|---|---|
| ● | The<br> PEA will consider the Whistler mineral resource estimate which currently stands at 6.48 million<br> ounces (Moz) gold equivalent (AuEq) compiled from the indicated resource category and 4.16<br> Moz AuEq in the inferred resource category (see Table 1 for details). The Project<br> is anticipated to benefit from the deposit’s near-surface, higher-grade core material<br> in the early years of production. |
| ● | The<br> PEA will utilize an updated mineral resource estimate to be completed by Moose Mountain Technical<br> Services, which will include 2024 drilling that was not available for the previous mineral<br> resource estimate. In addition, metallurgical test work is currently being conducted by Base<br> Metallurgical Laboratories Ltd., as previously announced on April 24, 2025. |
| ● | The<br> Company completed a comprehensive bidding process, receiving initial expressions of interest<br> from 13 consulting firms, followed by a rigorous Request for Proposal (“RFP”)<br> review of six shortlisted candidate firms. Ausenco was selected from this process on the<br> strength of its experience across all disciplines and its track record in recent delivery<br> of comparable studies. |
TimSmith, Chief Executive Officer of U.S. GoldMining, commented: “We’re delighted to be able to announce that we have partnered with Ausenco on this important work program. We’re excited to begin working towards delivering the first PEA on Whistler, which we believe could present a robust future mining opportunity and has the potential to unlock significant value for shareholders. We look forward to providing periodic updates as the study progresses, for which we are currently targeting completion before year-end.”
DavidThomas, Vice President, Minerals & Metals, Southwest USA of Ausenco, commented: “Ausenco is pleased to partner with U.S. GoldMining on the Whistler Gold-Copper Project PEA. We’ve successfully completed studies for clients around the world, including initial concept studies, pre-feasibility studies and definitive studies. As a lifelong Alaskan who lived many years in the Matanuska-Susitna (Mat-Su) Borough – where the Whistler Project is located - I’m delighted to add to the direct Alaskan experience of the team and help deliver U.S. GoldMining a robust, sustainable mining study.”

Notes to Table 1:
| 1. | Mineral<br> resources are not mineral reserves and do not have demonstrated economic viability. There<br> is no certainty that all or any part of the mineral resources will be converted into mineral<br> reserves. |
|---|---|
| 2. | Inferred<br> mineral resources are subject to uncertainty as to their existence and as to their economic<br> and legal feasibility. The level of geological uncertainty associated with an inferred mineral<br> resource is too high to apply relevant technical and economic factors likely to influence<br> the prospects of economic extraction in a manner useful for evaluation of economic viability. |
| 3. | The<br> mineral resource estimate for the Whistler, Island Mountain, and the upper portions of the<br> Raintree West deposits have been confined by an open pit with “reasonable prospects<br> of economic extraction” using the following assumptions: |
| ● | Metal<br> prices of US$1,850/oz gold (Au), US$4.00/lb copper (Cu) and US$23/oz silver (Ag); |
| --- | --- |
| ● | Payable<br> metal of 95% payable for Au and Ag, and 96.5% payable for Cu; |
| ● | Refining<br> costs for g of US$8.00/oz, for Ag of US$0.60/oz and for Cu of US$0.05/lb; |
| ● | Offsite<br> costs for Au of US$77.50/wmt, for Ag of US$3.50/wmt and for Cu of US$55.00/wmt; |
| ● | Royalty<br> of 3% net smelter return royalty (NSR); |
| ● | Pit<br> slopes are 50 degrees; |
| ● | Mining<br> cost of US$2.25/t for waste and mineralized material; and |
| ● | Processing,<br> general and administrative costs of US$7.90/t. |
| 4. | The<br> lower portion of the Raintree West deposit has been constrained by a mineable shape with<br> “reasonable prospects of eventual economic extraction” using a US$25.00/t cut-off. |
| --- | --- |
| 5. | Metallurgical<br> recoveries are: 70% for Au, 83% for Cu, and 65% Ag for Ag grades below 10g/t. The Ag recovery<br> is 0% for values above 10g/t for all deposits. |
| 6. | The<br> NSR equations are: below 10g/t Ag: NSR (US$/t)=(100%-3%)*((Au*70%*US$54.646/t) + (Cu*83%*US$3.702*2204.62<br> + Ag*65%*US$0.664)), and above 10g/t Ag: NSR (US$/t)=(100%-3%)*((Au*70%*US$56.646g/t) + (Cu*83%*US$3.702*2204.62)). |
| 7. | The<br> Au Equivalent equations are: below 10g/t Ag: AuEq=Au + Cu*1.771 +0.0113Ag, and above 10g/t<br> Ag: AuEq=Au + Cu*1.771. |
| 8. | The<br> specific gravity for each deposit and domain ranges from 2.76 to 2.91 for Island Mountain,<br> 2.60 to 2.72 for Whistler with an average value of 2.80 for Raintree West. |
| 9. | Numbers<br> may not add due to rounding. |
