Gold X2 Mining Inc.: Grade Control Drilling at Moss Main Zone Defines Higher Grade Corridors Intersecting 78.4m of 1.44 g/t Au from 15.6m

Press Release

VANCOUVER, B.C., November 13, 2025: Gold X2 Mining Inc. (TSXV: AUXX / OTCQB: GSHRF / FWB: 8X00) (“Gold X2” or the “Company”), is pleased to announce the third batch of assay results from its ongoing grade control drill program, with nineteen shallow holes targeting the marginal to core shears within the Main Zone at the Moss Gold Project in Northwest Ontario, Canada (the “Moss Gold Project”).

Michael Henrichsen, CEO of GoldX2 commented, “We are pleased with the latest batch of results that show long continuous broad intervals of gold mineralization that continue to align with our geological model.  In addition, higher grade internal intervals within these broad intercepts line up well between drill holes demonstrating continuity and furthers our understanding of the geometry of high grade with the deposit with higher density drilling.  This information is crucial as we look to define higher grade zones that could positively impact the economic performance of the deposit moving forward.”

Highlights

    • 18.2m of 3.41 g/t Au from 74.8m
  • 68.0m of 1.22 g/t Au from 6.0m in MMD-25-247, including
    • 15.05m of 2.36 g/t Au from 32.95m, and
    • 4.0m of 5.48 g/t Au from 69.0m
  • 49.4m of 1.10 g/t Au from 1.3m in MMD-25-251, including
    • 23.05m of 1.73 g/t Au from 2.95m

• In addition to the high-grade mineralized intercepts reported within the mineralized near-surface, high-grade shear corridors, the Moss Main grade control program outlined the following additional high-grade intercepts:
  • 5.1m of 5.6 g/t Au from 152.0m in MMD-25-232
  • 4.0m of 8.32 g/t Au from 178.0m in MMD-25-233
  • 7.0m of 5.07 g/t Au from 125.0m in MMD-25-249

Technical Overview

The results of the current grade control drill program are illustrated in the following figures and tables. Figure 1 shows the location map of the drill holes reported in this release, relative to the Moss Main grade control drill program. Figure 2 provides a cross-section of drill holes MMD-25-226, MMD-25-228, MMD-25-242, MMD-25-245, and MMD-25-251 representing the third easternmost section of the pattern. The results are summarized in Tables 1-1, which include significant intercepts (Table 1) and drill hole locations (Table 2).

In preparation for the infill drilling campaign, two grade control drilling programs were designed, one at each the Main and QES zones. The Main Zone pattern covers an area that is 100 meters along strike, 80 meters across strike and 170-190 meters deep. Drill holes are spaced in a 12.5-meter diamond-shaped pattern. All hole at the Main zone pattern have been completed with drilling activities shifted to the QES zone pattern.

These programs aim to investigate the short distance behaviour of gold mineralization, informing the determination of optimal drill spacing to upgrade Inferred Mineral Resources to Indicated Mineral Resources in preparation for the upcoming infill program. Additionally, the remaining half core will supply the required volume of sample for the upcoming feasibility level metallurgical studies. Finally, the tight spaced drilling provides mining-level precision that will derisk the Mineral Resource Estimate.

The assay data from the thirteen holes reported herein, and the previous twenty-one holes (press release dated September 10th, 2025, and October 29th, 2025), have outlined two main parallel shears consistently containing greater than 2.5 g/t gold mineralization, one of which runs along historical exploration drift. Intercepts include 2.0m of 11.59 g/t Au from 105.0m in MMD-25-228, 5.1m of 5.6 g/t Au from 152.0.0m in MMD-25-232, 4.0m of 8.32 g/t Au from 178m in MMD-25-233,  10.0m of 3.74 g/t Au from 147.0m in MMD-25-234, 7m of 3.25 g/t Au from 187.0m in MMD-25-241,  13.0m of 3.5 g/t Au from 22.0m in MMD-25-243, 15.2m of 5.93 g/t Au from 81.0m in MMD-25-245, 18.2m of 3.41 g/t Au from 74.8m in MMD-25-246, 4.0m of 5.48 g/t Au from 69.0m in MMD-25-247,  6.0m of 4.6 g/t Au from 148.0m in MMD-25-248, 7.0m of 5.07 g/t Au from 125.0m in MMD-25-249, 5.3m of 3.84 g/t Au from 98.0m in MMD-25-250, and 7.4m of 3.74 g/t Au from 82.6m in MMD-25-251.

Understanding the highest-grade portion of the mineralized shear system, which will drive any potential mining sequencing, will help ensure the most profitable mine plan can be developed in future technical studies. The knowledge gained from the grade control patterns will assist in properly defining these high-grade zones elsewhere in the mineral resource and will be factored into the development of the upcoming infill program.

The logging of the additional holes has been in line with the geology predicted from the earlier drilling. The mineralized intersections continue to be defined in moderately to strongly sheared diorites and granodiorites with either sericite-chlorite or sericite-silica-hematite altered and pyrite±chalcopyrite mineralization. The consistency and predictability of the geology and assay results will support the modelling of a robust short-range geological model to support future exploration targeting and MRE estimations.
