U.S. GOLDMINING ISSUES YEAR-END LETTER TO SHAREHOLDERS (USGO)

ANCHORAGE, Alaska , Dec. 17, 2024 /PRNewswire/ - U.S. GoldMining Inc. (NASDAQ: USGO) (" U.S. GoldMining " or the " Company ") is pleased to issue the following letter from its Chairman, Alastair Still , to provide a year-end update highlighting the key achievements and progress made in 2024 on our 100% owned Whistler Gold-Copper Project in Alaska (" Whistler " or the " Project ") located 105 miles from Anchorage, Alaska , U.S.A.

Dear Fellow Shareholders,

U.S. GoldMining Inc. - Recapping a Transformative Year

As 2024 draws to a close, we reflect on a pivotal year for U.S. GoldMining and the advancement of the Whistler Gold-Copper Project. This year brought meaningful progress across exploration, resource development and community engagement, further strengthening the foundation for our future growth.

Key Achievements in 2024

In 2024, we achieved several significant milestones, reinforcing Whistler's position as a leading resource development opportunity in Alaska:

1. Doubling of Indicated Resources

We completed a major update to our mineral resource estimate, which increased Indicated resources by 117% to 6.5 million ounces gold-equivalent (AuEq) along with 4.2 million ounces AuEq in the Inferred category (see news release dated October 7, 2024 ) ¹ . This marks a critical step forward, enhancing our confidence in the quality and scale of the deposit.

2. Continued Exploration Success including 652.5m at 1.00 g/t AuEq

Our 2024 drill campaign delivered strong results, including:

• 652.5m at 1.00 g/t AuEq , further extending Whistler's high-grade core (see news release September 30, 2024 ); and,
• 120m at 1.00 g/t AuEq , highlighting a newly targeted high-grade zone in the western portion of the deposit (see news release November 18, 2024 ).

3. On Budget, Strong Environmental Stewardship with Robust Health & Safety

We completed over 13,000 feet (4006 meters) of drilling ahead of schedule and under budget, with zero safety incidents and no reportable environmental incidents . This success reflects the dedication of our team and the importance we place on responsible operations.

4. Laying the Groundwork for Development

Beyond exploration, we advanced multiple initiatives to prepare Whistler for its next phase:

• Conducted internal mining and metallurgical studies to inform future scoping work.
• Progressed environmental and archaeological studies to support eventual permitting.
• Collaborated with Alaskan authorities on the West Susitna Access Road, a project that will improve access to infrastructure and significantly enhance Whistler's long-term development prospects.

Supporting Local Communities

We are committed to ensuring that our activities benefit the communities where we operate. In 2024, we:

• Directed over $4.3 million into the Alaskan economy through partnerships with local contractors and suppliers.
• Contributed $60,000 to local organizations, supporting initiatives such as the Iron Dog Race and Skwentna Fly-In.

These efforts reflect our dedication to fostering strong relationships with local stakeholders and contributing to economic growth in south-central Alaska .

Positioned for a Strong 2025

As we look ahead, the outlook for gold, copper and silver remains positive and we believe Whistler is well-positioned to meet the growing demand for critical minerals. Copper, in particular, is essential for advancing the clean energy transition, making Whistler a potentially valuable contributor to the broader push for sustainable resource security. Alaska represents an attractive jurisdiction to invest in exploration and resource development, with five major hardrock mines currently in production and a comprehensive and efficient permitting regulatory system in place.

Whistler is also set to benefit from strong political support for resource exploration and development in Alaska at both the state and federal level. Following the recent general election, President-elect Trump provided very encouraging messaging about the future of mining in Alaska , stating "During my second term we will continue the fight for Alaska like never before" and "we will maximize Alaska's mining potential." (see President Trump's message on Alaska ).

Additionally, with the anticipated development of the West Susitna Access Road, we are aligned with municipal and state government efforts to support responsible resource development. Together, these factors provide a compelling path forward as we continue to advance the project.

Closing Thoughts

This has been a transformative year for U.S. GoldMining, and we are encouraged by the momentum we've built. The growing M&A activity in the mining sector and the clear appetite from major producers to acquire large, technically strong projects in safe jurisdictions, underscores Whistler's strategic importance.

Thank you to our shareholders, employees, and local partners for your continued support as we work to deliver long-term value through the Whistler Gold-Copper Project.

Wishing you a safe and prosperous New Year.

Sincerely,

Alastair Still
