Analysis

This announcement outlines mobilization for the 2026 Whistler exploration program, targeting multiple near-deposit and district-scale gold-copper prospects and leveraging a PEA with after-tax NPV5% of up to $4.9B and IRR up to 62%. It follows recent technical report filings and management build-out around Whistler. Investors may focus on how drilling converts targets into defined resources and whether future studies advance toward Pre-Feasibility while maintaining the PEA’s payback and return metrics.

Key Terms

preliminary economic assessment, npv5%, internal rate of return, s-k 1300, +3 more

7 terms

preliminary economic assessment technical

"The exploration strategy complements the strong Whistler economics and rapid payback demonstrated in the recently announced Whistler initial economic assessment ("PEA")"

A preliminary economic assessment is an initial analysis that estimates the potential profitability and feasibility of a project or resource, such as a new mineral deposit or development venture. It provides a rough idea of costs, benefits, and risks, helping investors decide whether to pursue more detailed studies. This early evaluation is important because it offers a snapshot of whether the project is worth further investment and development.

npv5% financial

"After-tax net present value at 5% discount rate ("NPV5%") of $2.0 billion"

Net present value at a 5% discount rate (NPV 5%) measures the current worth of a sequence of expected future cash flows after shrinking them by 5% per year, like comparing getting money now versus in the future with a 5% annual “cost” for waiting. Investors use NPV 5% to judge whether an investment or project creates value: a positive number suggests the returns exceed that 5% benchmark, while a negative number implies the money would be better used elsewhere.

internal rate of return financial

"an internal rate of return ("IRR") of 33%, and initial payback of 2.1 years"

A percentage that represents the annualized yield an investment would earn, taking into account the timing and amount of all cash inflows and outflows; mathematically it is the rate that makes the discounted sum of future cash flows equal the initial cost. Investors use it to compare different projects or deals the way they compare interest rates — a higher internal rate of return suggests a stronger potential payoff, but it does not by itself show risk, scale, or timing nuances.

s-k 1300 regulatory

"the S-K 1300 Report titled "Whistler Gold-Copper Project, S-K 1300 Technical Report Summary"

Regulation S-K Item 1300 is a U.S. securities disclosure rule that requires public companies to report how they manage cybersecurity risks and to promptly disclose material cyber incidents. Think of it as a requirement to tell investors both the company’s “cyber health” plan and any major break-ins, similar to a homeowner explaining their alarm system and alerting neighbors after a burglary. This helps investors assess operational risk and potential financial or reputational impact.

ni 43-101 regulatory

"the 43-101 Report titled "Whistler Gold-Copper Project, NI 43-101 Technical Report and Preliminary Economic Assessment""

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

qualified person regulatory

"Mr. Smith is a qualified person as defined under NI 43-101 and S-K 1300."

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

porphyry technical

"targets for new gold-copper porphyry discoveries in the Whistler Orbit."

A porphyry is a type of large, underground mineral deposit that contains valuable metals such as copper, gold, or molybdenum, often spread over a wide area. Think of it as a giant underground treasure chest, where the metals are embedded in rock formations. These deposits are important to investors because they can be the source of significant resource extraction projects with the potential for substantial economic returns.

ANCHORAGE, Alaska, April 20, 2026 /PRNewswire/ - 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 ("NPV_5%") 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 NPV_5% 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."

________________________________ 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.

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.
    
    
  • 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.
