Gold X2 Intersects up to 50.85m of 2.18 g/t Au from 1.15m in Moss Main Zone Grade Control Drilling Program

Press Release

September 10, 2025

VANCOUVER, B.C., September 10, 2025: Gold X2 Mining Inc. (TSXV: AUXX / OTCQB: GSHRF / FWB: 8X00) (“Gold X2” or the “Company”), is pleased to announce the first batch of assay results from its ongoing grade control drill program at the Moss Gold Project in Northwest Ontario, Canada (the “Moss Gold Project”). The first batch of assay results targeted marginal to core shears in the Main Zone with a total of 18 shallow holes reported. The purpose of the 12.5 meter by 12.5 meters spaced grade control drill program is to investigate the short-distance behaviour of gold mineralization to determine the drill spacing required to upgrade the resource from inferred to indicated category.  Additionally, the drill core will provide the required volume of samples for the upcoming feasibility level metallurgical studies. Finally, the tight spaced drilling provides mining-level precision that will derisk the Mineral Resource Estimate.

Michael Henrichsen, CEO of Gold X2 commented, “We are pleased with the initial results of the first 18 drill holes from the Moss Main grade control program. Notably, gold grades are generally higher than those predicted in our current resource model and we look forward to the potential continuation of this pattern as we receive additional results.  Equally important, the observed continuity of shear zones supports our current geological model, currently being updated by G Mining Services, and this alignment reinforces our confidence in the Moss Gold Project’s potential.”

Highlights

• Sixty-one short drill holes have been completed as part of close-spaced grade control drill program designed to investigate the short-distance behaviour of gold mineralization at the Main Zone.

• Results from the first eighteen holes have confirmed the continuity of high-grade mineralization within individual shear zones modelled in the Main Zone. The top drill intercepts include:
  • 49.85m of 1.54 g/t Au from 0.7m in MMD-25-201, including
    • 36.3m of 2.03 g/t Au from 0.7m, and
  • 16m of 3.14 g/t Au from 76.0m
  • 50.85m of 2.18 g/t Au from 1.15m in MMD-25-203
  • 41m of 1.71 g/t Au from 5.0m in MMD-25-207
  • 57.5m of 1.26 g/t Au from 4.6m in MMD-25-209
  • 32m of 1.55 g/t Au from 7.0m in MMD-25-211
  • 64.1m of 0.96 g/t Au from 35.85m in MMD-25-214
  • 20.25m of 2.73 g/t Au from 147.0m in MMD-25-215, including
    • 9.7m of 5.35 g/t Au from 157.55m
  • 22.7m of 2.21 g/t Au from 168.0m in MMD-25-217

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-25-211, MMD-25-213, MMD-25-215, and MMD-25-217, representing the easternmost section of the pattern. The results are summarized in Tables 1-3, which include significant intercepts (Table 1), drill hole locations (Table 2), and a comparison of drilling results versus results from the resource model (Table 3).

Figure 2: Illustrates a drill section through MMD-25-211 to MMD-25-217 confirming several close-spaced, anastomosing, high-grade gold-mineralized shear zones modelled in the Main Zone.

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.

The logging data from the eighteen holes reported herein highlights reasonable continuity of the lithological and shear domains supporting the resource estimation process. Drilling intersected the typical diorite complex across most holes, characterized by 20-30-meter-wide units of varying composition, ranging from more mafic diorites to more felsic granodiorites. The exception is the most northern holes which collared into a 15-25m wide dacite volcanic unit.

The mineralized intersections are moderately to strongly sheared and either sericite-chlorite or sericite-silica-hematite altered with pyrite and chalcopyrite mineralization. The close spaced holes have confirmed that lithological units and shear zones are traceable vertically along the section with minimal pinching and swelling between the holes supporting the current geological interpretation used to guide the resource modelling.

Table 3 is a comparison of actual intercept values versus intercepts predicted by the current resource model. This shows that drilling has intersected slightly narrower but higher-grade shears, as would be expected in an anastomosing shear system. The improvement is attributed to the use of HQ sized drill core versus the historical mix of BQ and NQ sized drill core used to populate the resource model, as the geological continuity is robust.

Analytical and QA/QC Procedures

The HQ diameter drill core has been oriented using ACTIII or equivalent tools and validated in the core shack. All core has been sawed in half cut just off the core orientation line (bottom of hole) with the right half (looking down hole) of the core bagged and sent a third-party analytical laboratory. The left half of the core was returned to core boxes and is stored at Goldshore’s Kashabowie core yard facility.

All samples were sent to ALS Geochemistry in Thunder Bay for preparation and analysis was performed in the ALS Vancouver analytical facility. ALS is accredited by the Standards Council of Canada (SCC) for the Accreditation of Mineral Analysis Testing Laboratories and CAN-P-4E ISO/IEC 17025. Samples were analysed for gold via fire assay with an AA finish (“Au-AA23”) and 48 pathfinder elements via ICP-MS after four-acid digestion (“ME-MS61”). Samples that assayed over 10 ppm Au were re-run via fire assay with a gravimetric finish (“Au-GRA21”).

In addition to ALS quality assurance / quality control (“QA/QC”) protocols, Goldshore has implemented a quality control program for all samples collected through the drilling program.  The quality control program was designed by a qualified and independent third party, with a focus on the quality of analytical results for gold. Analytical results are received, imported to our secure on-line database and evaluated to meet our established guidelines to ensure that all sample batches pass industry best practice for analytical quality control. Certified reference materials are considered acceptable if values returned are within three standard deviations of the certified value reported by the manufacture of the material. In addition to the certified reference material, certified blank material is included in the sample stream to monitor contamination during sample preparation. Blank material results are assessed based on the returned gold result being less than ten times the quoted lower detection limit of the analytical method. The results of the on-going analytical quality control program are evaluated and reported to Goldshore by Orix Geoscience Inc.
