USGO US GoldMining Inc

ANCHORAGE, Alaska, Nov. 18, 2024 /CNW/ - U.S. GoldMining Inc. (NASDAQ: USGO) ("U.S. GoldMining" or the "Company") is pleased to announce new assay results from the 2024 confirmatory diamond core drilling program completed at the Whistler Gold-Copper Project (the "Project") in Alaska, U.S.A. The results reported in this news release will highlight WH24-02, which was drilled from within the Whistler Deposit (the "Deposit").

Selected Highlights:

• WH24-02 intersected high-grade mineralization within the western portion of the Whistler Deposit: 
  • Main Zone intercept of 120 meters (m) at 0.72 grams per tonne (g/t) gold (Au), 0.16 percent (%) copper (Cu) and 0.83 g/t silver (Ag), or 1.00 g/t gold equivalent (AuEq)^*, from 291 m to 411 m down hole;
  • Including higher-grade intercepts:
    • 40 m at 1.28 g/t AuEq from 297 m downhole; and
    • 20 m at 1.26 g/t AuEq from 357 m downhole.
  • Total mineralized envelope comprises 274 m at 0.71 g/t AuEq (0.48 g/t Au, 0.12% Cu and 0.86 g/t Ag) from 227 m to 501 m below surface.
• Assays remain pending for an additional three drill holes from the Company's recently completed 2024 drilling program which exceeded 4,000 meters for the season.

Tim Smith, Chief Executive Officer of U.S. GoldMining, commented: "Based on our evolving geological understanding originating from the successful 2023 drilling program, our technical team continues to identify opportunities to test under-drilled portions of the Whistler Deposit for zones of higher-grade mineralization. A component of the 2024 drill program subsequently focused on confirmatory drilling within the western portion of the Deposit, where as a result of the Company's relogging program and geochemical zonation modeling, WH24-02 targeted a zone of postulated high-grade mineralization, yielding 120 m at 1.00 g/t AuEq. We hope to build upon this program with the goal of further upgrading the existing mineral resource profile of the Project.

I want to again acknowledge our professional and hard-working technical team that have consistently advanced and unlocked value for the Whistler Gold-Copper Project, including their work in relation to the recent upgrade of the Whistler mineral resource estimate to 6.5 Moz AuEq in the indicated category plus an additional 4.2 Moz AuEq in the inferred category (see news release October 7, 2024)."

2024 Drilling Program

As reported on September 30, 2024, the Company drilled six diamond core holes for 4,006 meters during the 2024 field season at the Project. Drilling at the Whistler Deposit (see Figure 1) was aimed at further delineating and extending areas of high-grade mineralization within deeper portions of the Deposit, building upon the success of the 2023 drilling program which included a standout drill intercept of 652.5 m at 1.00 g/t AuEq, comprised of 0.73 g/t Au, 0.16% Cu and 1.5 g/t Ag from 7.0 m depth to 659.5 m down hole (WH23-03). 

Drilling Results Discussion

Whistler Deposit

The Whistler Deposit is hosted within the Whistler Intrusive Suite (Figure 2), a composite of diorite stocks and dykes that divide the suite broadly into an early Main Stage Porphyry ("MSP"), a later Intermineral Porphyry Suite ("IMP") and a late intrusive phase referred to as the Late Stage Porphyry ("LSP"). Gold and copper mineralization is characterized by abundant 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 the most strongly altered, veined and mineralized, with the IMP being less intensely altered and veined but remaining consistently mineralized.  Conversely, the late or post-mineralization LSP generally contains below cut-off grade material or is unmineralized. In addition, the Company's technical team has identified the presence of a robust core of higher-grade mineralization within the Deposit that correlates with intense alteration and B-veining within MSP in the eastern part of the intrusive suite.

In 2023, WH23-02 was drilled in the southwestern portion of the Whistler Deposit (Figure 2) in an area of untested IMP. The mineralized intercept, which comprised 142.3 m at 0.17 g/t Au, 0.21% Cu and 1.05 g/t Ag (or expressed as 0.51 g/t Au Eq) from 305 m depth downhole, successfully expanded mineralization southwards along strike. The elevated Cu to Au ratio in WH23-02 suggested that this mineralized intercept was located relatively high in the porphyry mineral system, and therefore it was postulated that enhanced grade gold mineralization may therefore occur at deeper levels. This observation was coupled with the recognition in deeper historic drill core of a zone of weakly mineralized to barren high temperature stockwork quartz veining. These 'deep early quartz veins' are interpreted to indicate high-temperature hydrothermal fluid ascent paths which have brought the Au-Cu mineralization up from below. The Company's geologists subsequently identified an intermediate level position with moderately higher grade mineralization above and lateral to this zone of 'deep early quartz veins', including historic drill intercepts such as 173 m at 0.63 g/t AuEq (WH05-07), 156 m at 0.66 g/t AuEq (WH07-03), and 203 m at 0.79 g/t AuEq (WH10-19). WH24-02 was drilled to target this intermediate level where the Company's geologists postulated that high-grade mineralization may be located directly overlying the zone of 'deep early quartz veins'. 

Within an overall envelope of 274 m at 0.71 g/t AuEq, WH24-02 transitioned with depth into higher Au:Cu ratio mineralization, intersecting higher grade mineralization as predicted immediately above the zone of 'deep early quartz veins':

• Main Zone intercept of 120 m at 0.72 g/t Au, 0.16 % Cu and 0.83 g/t Ag, or 1.00 g/t AuEq, from 293 m to 500.1 m down hole;
• Including the following high grade intercepts:
  • 40 m at 1.28 g/t AuEq (0.82 g/t Au, 0.25% Cu, 1.13g/t Ag) from 297 m downhole; and
  • 20 m at 1.26 g/t AuEq (0.96 g/t Au, 0.16% Cu, 0.93 g/t Ag) from 357 m downhole.

The standalone gold grade in the mineralized intercept within WH24-02 is 2-3 times higher than that intersected in WH23-02 and the surrounding historic drill holes, thus supporting the Company's thesis related to gold grade zonation above the 'deep early quartz veins' and providing confidence in our predictive targeting capability and ability to vector towards potential higher-grade mineralization in other parts of the Deposit.

Data Verification

For the Whistler Project drill core sampling program, samples were taken from NQ/HQ diameter core by sawing the drill core in half, with one-half sent to Bureau Veritas Commodities Canada Ltd. ("BV") in Fairbanks, Alaska, for sample preparation, then to BV's analytical laboratory in Vancouver, Canada for assaying, and the other half of the core is retained at the site for future reference. Sample lengths downhole were generally 2.0 m, except where samples were taken to honor geological contacts. 

BV is a certified commercial laboratory and is independent of U.S. GoldMining. The Company has implemented a quality assurance and quality control program for the sampling and analysis of drill core samples, including duplicates, mineralized standards and blank samples for each batch of core samples. The gold analyses were completed by lead collection fire assay fusion with AAS finish (FA430 method) on 30 grams test weight. Copper, silver and other base metals assays (total suite of 45 elements) were assayed by 4-acid digestion and ICP-MS analysis (MA200 method) on 0.25 grams test weight.
