Gold X2 Mining Inc.

Technical Program Updates

**Exploration:**Gold X2 embarked on a 160,000-meter drill program earlier this year, commencing with the three long-term-secured drill rigs and expanding to six rigs in July. The Company is currently looking to add an additional three rigs when they become available from our selected contractors. This will lift our drilling rate to 20,000 to 25,000 meters per month.

The Company has completed 223 holes (99,257 meters), as of September 15, 2026. The primary focus is on:

• Resource Expansion (101 holes, 51,575 meters) - Targeting extensions below and adjacent the current RPEEE pit shell, with a focus at QES Deeps. Highlight: 173.0m of 0.89 g/t Au from 685.0m in MQD-26-474

• Resource Development (109 holes, 42,303 meters) - Infill drilling to upgrade Inferred resource blocks to Indicated plus geotechnical drilling to define pit slope parameters for open pit design work. Highlights: 26.65m of 4.22 g/t Au from 197.7m in MMD-26-415 - Main Zone 86.0m of 1.37 g/t Au from 314.0m in MQD-26-366 - QES Zone A comparison between drill holes and the current MRE is showing positive reconciliation suggesting a significant addition of unmodelled, medium-grade, secondary shears

• Exploration (13 holes, 5,379 meters) - Targeting brownfields prospects near the Moss Deposit, focussing on Span. Highlight: 40.4m of 2.05 g/t Au from 343.6m in MSD-26-404

• Target Generation - Expanding the systematic coverage of IP gradient array geophysics and bedrock chemistry to the ground acquired from Kesselrun Resources in 2025 with a view to generating scout drilling targets on the extensions of the known mineralized trends. Geochemical surveys have also commenced at Star Lake. All programs will be completed before winter.

Next Steps: Complete the remaining 60,000 meters ahead of a December 31 cutoff for resource modelling. The Company intends to deliver an updated Mineral Resource Estimate for the Moss Gold Project in Q1 2027, which will be followed by a mine optimisation program in Q2 2027 to define the optimum pit size, mining rate, mining schedule and mill throughput. This will form the basis of a Technical Study, a formal Project Description, and pave the way toward a Feasibility Study and formal permitting process in Q1 2028. Drilling in 2027 will prioritise infill drilling to upgrade Inferred resource blocks to Indicated and commence scout drilling of new targets.

**Project Development:**Gold X2 has been progressing several pre-feasibility studies to support the next Technical Study planned for 2027. These studies include:

• Evaluating tailings disposal options, as well as potential tailings and waste management sites with SRK Consulting

• Geotechnical drilling to define pit slope parameters for open pit design work with Knight Piésold

• Evaluating route options for the power spur to site with Warrior Engineering and N-Sci and, importantly, submitting the application to IESO as part of an initiative to secure power from the Waasigan Line

• Completed an evaluation of metallurgical process flow sheet options and tailoring of the pre-feasibility level test program with Woods Process Services. Sampling is underway and test work will commence in October.

• Commenced the claims to lease process with Tulloch to ensure surface and mining rights over the mine area.

Additional studies will be commissioned in 2027, including a water management and diversion options studies.

**Environmental Baseline:**The Company has been progressing its existing conditions studies (baseline), which will form the basis of future monitoring studies, over the main Project area with CSL Geotechnical and Environmental and its subsidiaries. ERM Consulting was brought on board to complete a gap analysis of the existing conditions work in preparation for the Impact Assessment Process. Gold X2 has been working to implement ERM's recommendations, some of which will continue into Spring 2027, including:

• Terrestrial biology studies will be completed Q4 2026

• Hydrogeological studies and evaluation of major lake boundaries, culminating in a numerical water model, should be completed in Q1 2027

• Aquatic biology studies will complete Q2 2027

• Socio-economic baseline was completed Q3 2026. Further refinement will be required based on engagement with Indigenous communities in 2027.

• Air quality monitoring stations were installed Q3 2026. Monitoring will continue into Q3 2027.

Additional existing conditions studies are being planned for the proposed power line corridor, potential sites of tailings management facility and mined rock. These programs will run throughout 2027 and into 2028. Hydrology sampling and weather monitoring, which commenced in 2021, will continue for the life of the Project.
