Gold X2 Mining Inc. (TSX-V: AUXX) (OTCQB: GSHRF) (FWB: DF8) is pleased to announce the first batch of assays from the drillhole extension program targeting the bottom of the RPEEE (Reasonable Prospect for Eventual Economic Extraction) pit shell within the QES Zone at the Moss Gold Project in Northwest Ontario, Canada.

Michael Henrichsen, CEO of Gold X2 commented, “We continue to be encouraged by our infill drill program targeting the bottom of the open pit at the QES Zone. The long widths of plus 1 g/t Au with higher grade intervals above 3 g/t Au demonstrate the optionality offered by the Moss Gold Project. We are looking at the potential to both deepen the open pit and/or pursue underground mining scenarios with the support of additional drilling.

The Company is currently planning to increase the number of drills on site moving from 3 to 5 over the next month as we look to aggressively pursue resource growth in 2026.”

Highlights

• Five drillholes, drilled as part of the 2025 drilling program and targeting the Superion Zone, were extended to infill gaps in the resource model where no grade was interpolated because of sparse drilling, as well as low grade Inferred blocks in the base of the current RPEEE pit shell. Results confirmed the broad low-grade intercepts across the QES Zone in this volume with localized higher grades in shears. Select intercepts include:

• 51.0m of 0.73 g/t Au from 473.0m in MQD-25-148, and
  • 29.25m of 0.61 g/t Au from 531.0m

• 55.0m of 0.97 g/t Au from 507.0m in MQD-25-176, including
  • 19.2m of 1.35 g/t Au from 517.0m, and
  • 45.2m of 0.57 g/t Au from 570.0m

• 88.6m of 0.96 g/t Au from 481.4m in MQD-25-177, including
  • 46.8m of 1.36 g/t Au from 500.0m, and
  • 26.05m of 1.11 g/t Au from 581.85m, including
    • 2.05m of 8.49 g/t Au from 587.2m

• 78.0m of 0.90 g/t Au from 523.0m in MQD-25-180, including
  • 6.6m of 4.59 g/t Au from 552.0m

• 100.75m of 1.50 g/t Au from 494.0m in MQD-25-181, including
  • 48.0m of 2.34 g/t Au from 521.0m, including
    • 14.0m of 3.94 g/t Au from 542.0m

Technical Overview

The results of the extension drill holes are illustrated in the following figures and tables. Figure 1 shows the location map of the drill holes reported in this release. Figure 2 provides a type cross-section through drill hole MQD-25-181. The results are summarized in Tables 1 and 2, which include significant intercepts (Table 1) and drill hole locations (Table 2).

Gold X2 identified nine holes from its 2025 Superion exploration program to be extended through the core shears of the QES Zone to infill the drill spacing near the bottom of the RPEEE pit shell. The infill will support the upgrading of the existing Inferred mineralized resource to Indicated. It will also add to the Mineral Resource where the data spacing has been too sparse to interpolate gold grades into the shear domains. The holes were extended 50-100m past the edge of the RPEEE pit to intersect additional marginal shears that may provide support for a larger pit scenario.

The first five holes – MQD-25-148, -176, -177, -180 and -181 – resumed drilling within the gabbro-diorite within the diorite complex. The holes each intersected a similar wide section of moderate to strongly sheared sericite-hematite-silica altered granodiorite containing 2-3% pyrite ± chalcopyrite within the core shears outlined in the highlighted intercepts section above. The drilling was then extended through the diorite complex into the southern dacitic volcanics containing multiple 5-10m wide diorite and granodiorite dykes. These dykes were locally weak-moderately sheared with similar sericite-hematite-silica alteration as seen in QES returning intercepts including 8.6m of 1.86 g/t Au from 616.4m, including 3.0m of 4.58 g/t Au from 618m in MQD-25-148, 18.6m of 1.28 g/t Au from 641.3m, including 14.55m of 1.53 g/t Au from 643.45m in MQD-25-176, 21.4m of 0.5 g/t Au from 625m in MQD-25-177, 18.5m of 1.03 g/t Au from 611.5m, including 8.6m of 1.94 g/t Au from 617.0m in MQD-25-180, and 8.25m of 2.16 g/t Au from 634.15m in MQD-25-181.

Results from the final four holes are yet to be received.

As part of the move to infill drilling, Gold X2 conducted an exercise to evaluate PhotonAssay™ as an analytical technique that would offer a faster turnaround time at a more inexpensive price. The Company collected pulps from 2000 samples required for umpire test work and had them analysed by for PhotonAssay™ and fire assay by Paragon Geochemical. The analysis showed a P95 coefficient of variation of 8.3% with a 2.2% high bias toward fire assay results (Figure 4) for all samples above 0.1 ppm Au. This is within analytical precision of the methods for mineralized samples and was found to be acceptable for the Company to make the transition to PhotonAssay™ for routine analysis. A percentage of submitted samples will continue to compare PhotonAssay™ and fire assay techniques to monitor performance over time.

About Gold X2 Mining

Gold X2 is a growth-oriented gold company focused on delivering long-term shareholder and stakeholder value through the acquisition and advancement of primary gold assets in tier-one jurisdictions. It is led by the ex-global head of structural geology for the world’s largest gold company and backed by one of Canada’s pre-eminent private equity firms. The Company’s current focus is the advanced stage 100% owned Moss Gold Project which is positioned in Ontario, Canada, with direct access from the Trans-Canada Highway, hydroelectric power near site, supportive local communities and skilled workforce. The Company has invested over $100 million of new capital and completed approximately 100,000 meters of drilling on the Moss Gold Project, which, in aggregate, has had over 300,000 meters of drilling. The 2026 updated NI 43-101 mineral resource estimate for the Moss and East Coldstream Deposits has expanded to 2.458 million ounces of Indicated gold resources at 1.04 g/t Au, contained within 73.8 million tonnes and 4.209 million ounces of Inferred gold resources at 0.97 g/t Au contained within 134.7 million tonnes. The Moss Deposit also has a silver MRE of 3.160 million ounces of indicated silver resources at 1.53 g/t Ag contained within 64.3 Mt and 6.273 million ounces of inferred silver resources at 1.55 g/t Ag contained within 125.9 Mt. Results of a preliminary economic assessment of the Moss Gold Project suggest the potential for the deposit to support a long-life mining operation with a strong production profile and low production costs. The MRE and PEA are supported by a NI 43-101 technical report for the Moss Gold Project available on the Company’s website and under the Company’s issuer profile on SEDAR+.
