Highlights:

The highlights of U.S. Goldmining’s announcement include:

• Indicated Mineral Resource: 294 million tonnes ("Mt") at 0.68 grams per tonne ("g/t") gold equivalent ("AuEq") for 6.48 million ounces ("Moz") AuEq
• Inferred Mineral Resource: 198 Mt at 0.65 g/t AuEq for an additional 4.16 Moz AuEq
• Estimated gold equivalent ounces in the indicated category have increased by approximately 117% compared to the 2022 MRE*
• The Whistler MRE was constrained using a series of conceptual pit design shells for the Whistler deposit, which assumed a first phase with an estimated 22.4 Mt of mineralized material at a grade of 1.04 g/t AuEq and a strip ratio of 0.08:1 (waste:ore)
• The three Au-Cu-Ag porphyry deposits comprised within the Whistler MRE – Whistler, Raintree and Island Mountain – occupy approximately 1% of the U.S. GoldMining’s land holdings and occur within a cluster of high priority targets sharing key geological characteristics with the known deposits, thereby highlighting the broader exploration potential of the Project
• S. GoldMining is currently systematically exploring nearby targets within the ‘Whistler Orbit’ where an additional 12 potential targets remain under-explored
• The Whistler MRE encompasses 2023 drilling as reported earlier this year (see U.S. GoldMining news release January 16, 2024), including the initial intercept contained within WH23-03 which comprised 547 m at 1.06 g/t AuEq
• It excludes recently reported confirmatory assays from the re-entry of WH23-01 drilled in 2024 (see U.S. GoldMining announcement September 30, 2024) which now extends the mineralized intercept to 652.5m at 1.00 g/t AuEq
• The 2024 core drilling program has now concluded, achieving 4,006 meters of drilling in 6 holes.

Alastair Still, Chief Executive Officer of GoldMining, commented: "Since the initial public offering of U.S. GoldMining in April 2023, we are extremely pleased by the progress of its exploration initiatives at the Whistler Project, which have resulted in strengthened confidence of the Whistler MRE by increasing the gold equivalent ounces in the indicated category by approximately 117% from prior estimates. The Project now contains 6.5 Moz AuEq in the indicated resource category and an additional 4.2 Moz AuEq in the inferred resource category. The successful 2023 drilling program and growth of the mineral resources at Whistler is an example of how our spin-out strategy continues to unlock value for GoldMining shareholders. We now hold over $175 million in cash and equities¹ that help position us to advance strategic initiatives across our portfolio, which globally holds 12.5 million AuEq ounces of measured and indicated resources and 9.7 million AuEq ounces of inferred resources.^2”

The updated Whistler MRE is set forth in a technical report summary titled "S-K 1300 Technical Report Summary Initial Assessment for the Whistler Project, South Central Alaska" with an effective date of September 12, 2024, which was filed by U.S. GoldMining on October 7, 2024 under subpart 1300 of Regulation S-K ("SK-1300") and available under U.S. GoldMining’s profile at www.sec.gov (the "S-K 1300 Report"). U.S. GoldMining and GoldMining plan to file a technical report under Canadian National Instrument 43-101 (“NI 43-101”) in respect of the updated Whistler MRE within 45 days of U.S. GoldMining’s announcement.

Updated Mineral Resource Estimate Overview

The Whistler MRE was based on 43,096 meters of drill data available as of January 16, 2024 (refer to U.S. GoldMining’s news release dated January 16, 2024, for further details), prior to the commencement of U.S. GoldMining’s 2024 drill campaign. The author of the report conducted a site visit August 6, 2024, which included collection of independent duplicate samples for umpire laboratory analysis. The effective date for the updated MRE is September 12, 2024. The Whistler MRE is constrained within a revenue factor 1.5 pit shell and reported above a US$10/tonne cut-off value (equivalent to 0.27 g/t AuEq cut-off grade).

The October 2024 updated Whistler MRE incorporates:

• Revised mineral resource reporting at US$10/tonne cut-off (previously the 2022 MRE was reported at US$10.50/t) and using below 3-year trailing average commodity assumptions of US$1,850/oz Au, US$4.00/lb Cu and US$23/oz Ag, across all three Project deposits: Whistler, Raintree and Island Mountain (see Figure 1).
• The addition of three 2023 diamond core drill holes for 1,674 meters of drilling within the namesake Whistler Deposit (see Figure 2), with revisions to the geological interpretation and three dimensional mineralization modelling.

The following table sets forth a summary of the Whistler MRE update.

Additional details of the mineral resource estimate are set forth in the S-K 1300 Report and U.S. GoldMining’s news release dated October 7, 2024.

*For comparison, the previous 2022 MRE (Effective Date September 22, 2022) comprised 118 Mt at 0.79 g/t AuEq for 2.99 Moz AuEq Indicated resources, and 317 Mt at 0.63 g/t Au for 6.45 Moz AuEq Inferred resources, at a US$10.50/t cutoff value for open pit resources and US$25/t for underground resources.

Whistler Project High-Grade Core

The updated 2024 Whistler MRE is underpinned by a significant component of higher-grade mineralization within the core of the three deposits. Table 2 illustrates the Whistler MRE at a range of cut-offs which provide optionality for potential future mine development scenarios. For example, using an elevated cut-off value of US$20/t (equivalent to 0.37 g/t AuEq cut-off grade) for open pit resources, the Whistler MRE contains a robust higher grade subset resource of: 

In particular, U.S. GoldMining’s flagship Whistler Deposit, a component of the Whistler MRE, contains a high-grade core defined by coincident approximately ≥0.40 g/t gold and ≥0.20% Cu grade contours that extend approximately 500 m in the north-south dimension, 250 m in the east-west dimension and extend to 600 m depth (from surface), where it remains open down dip. The Whistler Deposit high-grade core offers the option to consider low strip ratio, higher – grade starter-pit scenarios. Table 3 provides an incremental breakdown of the Whistler Deposit as contained within sequentially expanding pit shells which are illustrated in Figure 3.

Whistler Project Geology

The Whistler Deposit is hosted within the Whistler Intrusive Suite (see Figure 2), a composite suite of diorite stocks and dykes with cross-cutting relationships that divide the suite broadly into an early Main Stage Porphyry ("MSP"), a later cross-cutting Intermineral Porphyry Suite ("IMP") and the latest cross-cutting intrusive phase referred to as the Late Stage Porphyry ("LSP"). Gold and copper mineralization is characterized by presence of disseminated sulphide and quartz + sulphide vein stockworks (including classic porphyry diagnostic ‘A’, ‘B’, ‘D’, and ‘M’ type veins), and potassic alteration which is variably overprinted by later phyllic alteration. The early-stage MSP suite is most strongly altered, veined and mineralized, with the IMP being less intensely altered and veined but remaining consistently mineralized, and the late or post-mineralization LSP generally being below cutoff grade or unmineralized. The ‘high-grade core’ correlates with intense potassic alteration and highest frequency of A and B veining within the MSP.

Based on re-logging of historical drill core in conjunction with the 2023 drilling program, the Whistler Deposit three-dimensional geological model was re-interpreted to include adjustments to geometry, extents and continuity of the MSP, IMP and LSP suites. These were used as a guide to create mineralization shells for both Au-Ag and Cu separately. The shells include a higher grade ‘core’, with lower grade shells also generated to constrain both Au-Ag and Cu mineralization. A significant change in the 2024 geological model is the removal of the ‘Divide Fault’, which defined a hard boundary between geological and geostatistical domains in previous iterations of the Whistler deposit model. Relogging and 2023 drilling has confirmed there is no compelling evidence for this fault, thus the previously modelled Divide Fault is no longer seen to influence the mineralization. Subsequently, gold and copper grade shells have been constructed to constrain the Whistler Deposit mineral block model, honoring the geological boundaries defined by the limits of the productive MSP and ISP, and taking into account the weakly to non-mineralized LSP.

Mineralization at Raintree West occurs as two main types: 1) porphyry-style gold-copper mineralization hosted by diorite porphyry stocks and consisting of quartz and magnetite stockwork veining, with vein and disseminated chalcopyrite associated with potassic alteration, and 2) later cross-cutting silver-gold-lead-zinc mineralization in quartz-carbonate veins with occasional banded epithermal-like textures. The early gold-copper mineralization is best developed within, and controlled by, early diorite porphyry intrusions (akin to MSP at the Whistler Deposit), whereas the later silver-gold-lead-zinc veins surround and locally overprint the porphyry mineralization and are most abundant in the host andesitic composition volcanic.

The Island Mountain deposit, located 20 km south of the Whistler-Raintree deposits, is comprised of a suite of nested intrusions, ranging compositionally from hornblende diorite to hornblende-biotite monzonite, with mineralization occurring predominantly within the ‘Breccia Zone’, comprising intrusive breccias occurring as sub-vertical 100-150 m diameter ‘pipes’ with pyrrhotite-pyrite-chalcopyrite mineralization, that host the bulk of gold-copper porphyry mineralization.
