Gold X2 Drilling Intersects 173.0m of 0.89 g/t Au 100m Beneath the RPEEE Pit at QES

Gold X2 Mining Inc. (AUXX) has released the first two assayed holes from its 21-hole QES Deeps resource expansion program at the Moss Gold Project in Northwest Ontario. The holes were collared on the southern flank of the QES Zone and intersected mineralization 75-100m below the current RPEEE pit shell.

MQD-26-465 returned 227.2m at 0.73 g/t Au from 637.8m, including: - 157.75m at 0.90 g/t Au from 707.25m - 42.0m at 1.43 g/t Au from 744.0m - 11.95m at 2.65 g/t Au from 790.05m

MQD-26-474 returned 271.6m at 0.73 g/t Au from 630.4m, including: - 33.5m at 0.87 g/t Au from 630.4m - 22.0m at 1.08 g/t Au from 631.0m - 173.0m at 0.89 g/t Au from 685.0m - 16.0m at 1.05 g/t Au from 696.0m - 8.0m at 4.86 g/t Au from 721.0m - 52.0m at 1.05 g/t Au from 767.0m

The company states the core shear zone is 170-180m in true width and that the holes remain 180m above the deepest hole, MQD-25-326. Twelve of the 21 planned QES Deeps holes are complete, with assays outstanding for the other 10 completed holes.

Gold X2 Mining Inc. (AUXX) is an advanced pre-development explorer with a preliminary economic assessment, not a producer. The equity is already priced on the existing resource and PEA. The company’s market capitalization is approximately C$986.8M using the Q2 share count and last provided close of C$9.76. The resource is already large: 2.458 moz indicated at 1.04 g/t Au and 4.209 moz inferred at 0.97 g/t Au.

The key prior QES Deeps result was MQD-25-326: 117m at 1.21 g/t Au, reported March 3, 2026. That hole had about 141.6 g.m and was framed as a deeper high-grade discovery. The new full interval of 271.6m at 0.73 g/t Au has higher g.m, about 198.3, but materially lower grade. This is a grade-for-width trade, not a clean upgrade. It likely helps scale, but the grade is below the current resource average.

For a large bulk-tonnage deposit with a 5.3:1 strip ratio, adding deeper low-grade tonnes below the pit may be less valuable than adding grade within the pit. It is incremental positive scale confirmation with a grade caveat. A 15% move seems unlikely on this release alone.

Gold X2 Mining Inc. (AUXX) is a gold exploration and development company focused on its 100%-owned Moss Gold Project in Northwest Ontario. The company’s land package has been expanded through the Kesselrun acquisition and the Star Lake option to approximately 40,456 hectares in the Shebandowan greenstone belt.

The Moss and East Coldstream deposits host indicated resources of 2.458 moz gold at 1.04 g/t Au within 73.8 Mt, and inferred resources of 4.209 moz gold at 0.97 g/t Au within 134.7 Mt. Additional silver resources are present at Moss.

A preliminary economic assessment (PEA) highlights a base-case after-tax NPV5% of C$2.232B, an internal rate of return (IRR) of 22.1%, and a payback period of 3.2 years. The project features an all-in sustaining cost (AISC) of US$1,188/oz Au and an initial capital expenditure (capex) of C$2.001B, with production of approximately 265,000 oz gold per year over a 13.2-year mine life.

The Company has no revenue and remains pre-production. As of Q2 2026, the financial position includes cash of C$105.6M, total assets of C$186.3M, total equity of C$156.6M, and no material bank debt.
