U.S. GoldMining (NASDAQ: USGO) updates Whistler PEA economics and 2026 drill plans
Rhea-AI Filing Summary
U.S. GoldMining Inc. has provided an update on its 2026 exploration program at the 100% owned Whistler Gold-Copper Project in Alaska. Camp opening and drill setup are underway, with drill crews expected on site in the coming weeks to test high-priority targets in the Whistler–Raintree area.
The company plans diamond core drilling to build a pipeline of new discoveries that can extend mineralization beyond the existing deposits. This program is intended to build on the recent Whistler preliminary economic assessment, which outlined an after-tax NPV5% of $2.0 billion, a 33% IRR, and a 2.1-year initial payback based only on Indicated Resources at base case metal prices.
The update also highlights regional infrastructure momentum. Neighbor Terra Energy Center has received $89 million in U.S. Department of Energy funding to assess a proposed 1.25‑gigawatt power plant with carbon capture and storage about 30 miles east of Whistler, reinforcing the business case for the State-proposed West Susitna Access Road and offering a potential long-term energy option for future project studies.

Exhibit 99.1
U.S. GoldMining Provides Updates on the 2026 Exploration Program and
District Infrastructure Catalysts at its 100% Owned Whistler Project, Alaska
Anchorage, Alaska – June 9, 2026 – U.S. GoldMining Inc. (NASDAQ: USGO) (“U.S. GoldMining” or the “Company”) is pleased to provide an update on the 2026 planned exploration program (the “Program”) at its Whistler Gold-Copper Project in Alaska (“Whistler” or the “Project”).
Highlights:
| ● | Camp Opening and Drill Setup Underway: The Company has successfully mobilized all critical equipment and consumables to the Project ahead of schedule. Crews are actively constructing drill pads at high priority targets, with the drilling crew expected to mobilize to site to commence drilling in the coming weeks. | |
| ● | Executing the Growth Strategy: The Program will feature diamond core drilling focused on high-priority targets within the Whistler – Raintree area (see Figure 1). The objective is to develop a pipeline of discoveries that can underpin significant step-out growth opportunities for the Project. | |
| ● | Building on a Strong, Conservative Economic Foundation: The upcoming exploration strategy is designed to build upon the recent Whistler initial assessment (“PEA”)1 (see news release March 2, 2026). The PEA, which incorporates only the Indicated Resources from the Whistler deposit, outlines an after-tax net present value at a 5% discount rate (“NPV5%”) of $2.0 billion, a 33% internal rate of return (“IRR”), and initial payback of 2.1 years, at base case prices. | |

Tim Smith, Chief Executive Officer of U.S. GoldMining commented: “We are pleased to report that our 2026 exploration program is ahead of schedule and on budget. Drill site preparation is actively underway, and we look forward to turning the drills in the coming weeks. Despite the recent volatility in global markets since the release of our Whistler PEA in early March, we remain highly confident in our ability to build upon the Project’s already strong economic and resource fundamentals through active exploration and systematic de-risking.
Furthermore, we are seeing powerful macro and regional catalysts align for Whistler. Copper fundamentals remain exceptionally strong due to tightening supply and structural deficits, with COMEX futures breaking record highs of $6.64/lb earlier this month – well above the $4.50/lb base case prices used in our PEA. Regionally, the recent DOE grant awarded to the proposed neighboring Terra Energy Center is a significant milestone for the district. In the short term, it greatly strengthens the business case for the West Susitna Access Road, and in the longer term, it introduces a potential reliable energy source for Whistler.”
1 All references to dollar amounts are to United States dollars unless otherwise stated. Base-case prices used in the 2026 Whistler PEA are $3,200 per ounce gold, $4.50 per pound copper, and $37.50 per ounce silver, based on long term market consensus prices as of February 2026.
