U.S. GoldMining (NASDAQ: USGO) launches 2026 Whistler drilling program
Rhea-AI Filing Summary
U.S. GoldMining Inc. has mobilized its 2026 exploration program at the Whistler Gold-Copper Project in Alaska, advancing drilling on several high-priority near-deposit and district-scale targets around the Whistler–Raintree area. The company has pre-positioned key equipment and supplies so summer drilling can begin as conditions allow.
The program builds on the recently announced Whistler preliminary economic assessment, which outlined an after-tax NPV at a 5% discount rate of $2.0 billion with a 33% IRR and a 2.1-year payback at base metal prices, and an after-tax NPV 5% of approximately $4.9 billion with a 62% IRR and 1.2-year payback at spot prices.

Exhibit 99.1
U.S. GoldMining Mobilizes 2026 Exploration Program Targeting District-Scale Potential at the Whistler Project, Alaska
Anchorage, Alaska – April 20, 2026 – U.S. GoldMining Inc. (NASDAQ: USGO) (“U.S. GoldMining” or the “Company”) is pleased to announce that it has commenced activities on its planned exploration program (the “Program”) at its Whistler Gold-Copper Project in Alaska (“Whistler” or the “Project”).
Highlights:
| ● | Executing Growth Strategy: The 2026 Program will comprise diamond core drilling targeting several high-priority near-deposit potential upside opportunities and new targets within the Whistler – Raintree area (see Figure 1). The objective is to develop a pipeline of discoveries that will underpin growth opportunities for the Project. |
| ● | Mobilization Underway: The Company has recently completed pre-mobilization of critical equipment and consumables to the Project. This proactive staging positions the exploration team to commence summer exploration activities and drilling as soon as conditions allow. |
| ● | Building on Strong Economic Foundation: The exploration strategy complements the strong Whistler economics and rapid payback demonstrated in the recently announced Whistler initial economic assessment (“PEA”)1. See news release dated March 2, 2026, which outlined: |
| ○ | After-tax net present value at 5% discount rate (“NPV5%”) of $2.0 billion, an internal rate of return (“IRR”) of 33%, and initial payback of 2.1 years, at Base Prices. | |
| ○ | At spot prices, an after-tax NPV5% of approximately $4.9 billion, an IRR of 62%, and an initial payback of just 1.2 years. |
| ● | Untapped Potential: The 2026 PEA considers only one of three deposits with stated mineral resource estimates on the property, highlighting the district-scale potential the upcoming program aims to unlock. |
Tim Smith, Chief Executive Officer of U.S. GoldMining commented: “We are excited to return to the field this coming summer to test our highest priority targets for new gold-copper porphyry discoveries in the Whistler Orbit. The strong initial base-case mine plan in the PEA gives us a strong foundation to confidently advance our exploration strategy. We look forward to sharing more details on the 2026 Program as we drive district-scale resource growth and the advancement of Pre-Feasibility level studies over the coming months.”
2026 Whistler Exploration Program
The Program will test several new high priority targets identified from the 2025 exploration program. These advanced targets exhibit strong indicators for the potential discovery of new bedrock porphyry gold-copper mineralization (see news release dated January 20, 2026):
| ○ | Whistler extensions (Near-Deposit Upside): Along-strike extensions of the Whistler deposit and new zones of copper anomalism identified in both basal till and top of bedrock sampling, located adjacent to the currently delineated Whistler deposit. | |
| ○ | Mammoth & Snow Ridge (District Scale Potential): Large strongly anomalous gold and/or copper zones located 2 to 3 kilometers north of the Whistler deposit. |
1 PEA notes: all financial figures are in United States dollars unless otherwise stated. Base Prices used in the 2026 Whistler PEA are $3,200 per ounce gold, $4.50 per pound copper, and $37.50 per ounce silver. References to spot prices reflect $5,000 per ounce gold, $5.85 per pound copper, and $70 per ounce silver. Spot prices were selected based on the 5-day and 1-month intra-day trading prices for the periods ending February 23, 2026.
| ○ | Raintree area (Near-Deposit Upside & Mineral System Scale Potential ): Widespread gold-copper anomalism suggestive of lateral extensions adjacent to the existing Raintree deposit, alongside broader regional targets. | |
| ○ | Hotfoot (the “Look-Alike”) and Sunbowl area: An emerging, high-priority target defined by an intense bedrock gold anomaly aligned with a large ‘Whistler look-alike’ magnetic signature, located just 1 kilometer south of the Raintree deposit, and additional along-strike extensions south of the Whistler deposit. |
