Grade Control Drilling at Moss Main Zone Continues to Delineate High Grade

Shear Corridors with Intersects of 69.65m of 1.63 g/t Au from 4.35m, Including

10.0m of 7.09 g/t Au

VANCOUVER, B.C., October 29, 2025: Gold X2 Mining Inc. (TSXV: AUXX / OTCQB: GSHRF /

FWB: 8X00) (“Gold X2” or the “Company”) is pleased to announce the next batch of assay results

from its ongoing grade control drill program, with thirteen 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 Gold X2, commented, "Our latest drill results continue to

demonstrate excellent continuity of mineralization at the Moss Main zone. These results validate

our geological model that will be utilized in our upcoming Mineral Resource Estimate to be

released in conjunction with the PEA. In addition, the results from grade control drilling will help

define the spacing for the infill drill program as we look toward advancing the Moss Deposit toward

a future feasibility study.”

Highlights

• Logging of the Moss Main grade control program has outlined strongly continuous

lithological domains and traceable shear corridors associated with high-grade mineralized

intercepts.

• Results from thirteen holes continue to confirm the presence of a near-surface high-grade

mineralized core at the center of the Moss Main zone previously defined primarily by

historical drilling. Select drill intercepts include:

o 31.3m of 1.92 g/t Au from 48.7m in MMD-25-199, including

▪ 11.0m of 4.58 g/t Au from 69.0m

o 73.25m of 1.01g/t Au from 9.75m in MMD-25-219, including

▪ 39.0m of 1.28 g/t Au from 20.0m, and

o 51.05m of 1.08 g/t Au from 33.85m in MMD-25-221, including

▪ 10.0m of 2.32 g/t Au from 65.0m

o 19.0m of 2.75 g/t Au from 163.0m in MMD-25-223, including

▪ 6.0m of 7.84 g/t Au from 166.0m

o 69.65m of 1.63 g/t Au from 4.35m in MMD-25-227, including

▪ 10.0m of 7.09 g/t Au from 13.0m

o 80.2 of 1.23 g/t Au from 15.0m in MMD-25-229, including

▪ 16.0m of 1.69 g/t Au from 17.0m and

▪ 20.0m of 2.47 g/t Au from 44.0m

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-

227, MMD-25-229, MMD-25-231, and MMD-25-233 (assays pending) , representing the third

easternmost section of the pattern. The results are summarized in Tables 1 -2, which include

significant intercepts (Table 1) and drill hole locations (Table 2).

Figure 1: Illustrates the Moss Main grade control drill program.

Figure 2: Shows a type section with reported intersections relative to the block model. Note: the block model has

factored volumes that cannot be illustrated on section.

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 logging data from the thirteen holes reported herein, and the previous eighteen holes (press

release dated September 10 th, 2025), highlight good continuity of the lithological and shear

domains supporting the resource estimation process. Drilling has outlined a predictable geological

sequence from north to south of a 15-25m wide dacitic volcanic package before a 100m wide

locally sheared epidote-chlorite altered mafic diorite with two 10-20m wide sericite-silica-chlorite

altered sheared diorite dykes and two 10 -20m wide sericite-hematite-silica altered sheared

granodiorite dykes. Drilling has also defined a 3-4m wide shallow dipping mafic dyke.

Three independent shear corridors have been defined and constrain the primary high grade

mineralized intersections with additional interconnecting minor shear zones noted between the

corridors associated with lower grade gold mineralization.

The mineralized intersections are moderately to strongly sheared and either sericite -chlorite or

sericite-silica-hematite altered with pyrite and chalcopyrite mineralization. The new holes further

support our understanding that lithological units and shear zones are traceable vertically and

horizontally across the sections with a slightly improved continuity noted along the shallowly

dipping lineation fabric.

Several holes returned intervals above the 30 g/t cut within the high -grade shear corridor

historically targeted by the underground exploration drift including 31.3m of 1.99 g/t Au (1.92 g/t

cut) from 48.7m, including 11.0m of 4.76 g/t Au (4.58 g/t cut) from 69.0m in MMD-25-199, 19.0m

of 4.52 g/t Au (2.75 g/t cut) from 163.0m, including 6.0m of 13.5 g/t Au (7.84 g/t cut) from 166.0m

in MMD-25-223, and 69.65m of 3.20 g/t Au (1.63 g/t cut) from 4.35m, including 10.0m of 18.0 g/t

Au (7.09 g/t cut) from 13.0m in MMD-25-227. The continuity of these very high -grade shears is

encouraging with follow up on separate, more sparsely drilled high grade shears expected to be

completed during the upcoming infill drill program.

mineralized diorite yielding an intercept of 10.0m of 7.09 g/t Au (18.0 g/t Au Uncut) from 13.0m, including 1.25m of

17.25 g/t Au from 17.75m and 1.2m of 30g/t Au (121 g/t Uncut) from 20.55m.

Intersections calculated above a 0.3 g/t Au cut off with a top cut of 30 g/t Au and a maximum internal waste

interval of 5 metres. Shaded intervals are intersections calculated above a 1.0 g/t Au cut off. Intervals in

bold are those with a grade thickness factor exceeding 20 gram x metres / tonne gold. True widths are

approximate and assume a subvertical body.
