Globex Reports Duquesne West High – Grade Shallow Gold Drill Intersections

Sep 9, 2026

September 9, 2026 – Toronto, Ontario, Canada. GLOBEX MINING ENTERPRISES INC. (GMX – Toronto Stock Exchange, G1MN – Frankfurt, Stuttgart, Berlin, Munich, Tradegate, Lang & Schwarz, LS Exchange, TTMzero, Düsseldorf and Quotrix Düsseldorf Stock Exchanges and GLBXF – OTCQX International in the US) is pleased to announce that Emperor Metals Inc. (Emperor) have reported additional results from the its 2026 exploration campaign at the Duquesne West Project, which is under option from Duparquet Assets Ltd, a 50% owned subsidiary of Globex. The program comprised 20,479 metres of new drilling and approximately 7,884 metres of previous unsampled historical core, generating more than 28,000 metres of combined drilling data to further refine and expand the resource model.

Highlights of Press Release:

· DQ26-52: 24.1 meters (m) grading 2.6 g/t Au

o including 7.1 m of 7.5 g/t Au from 45.2 m: 35 m vertical depth.

· DQ26-53: 14.3 m grading 2.2 g/t Au

o including 4.0 m of 7.4 g/t Au from 50 m: 39 m vertical depth.

· Assay results have now been received for 42 of 66 drill holes or 61% of the 20,479 m drilled during the 2026 program.

· With 142,758 m of drilling completed to date, these results represent another significant step toward Emperor’s objective of advancing the project to a Preliminary Economic Assessment (PEA) in the near term.

The drilling program on Duquesne West by Emperor Metals in 2025/2026 has been focused on reinforcing resource continuity, expanding the mineralised envelope, and delivering wider and more robust high-grade intervals adding to the Duquesne West’s compelling growth profile.

Results Summary

Exhibit’s 1 and 2 show the location of the drill holes discussed in this press release as well as previous drill results.

DQ26-52: This hole was designed to better define mineralized zones and structural controls that are now interpreted to be more robust and continuous than previously recognized (See Figure 1 and 2). Emperor believes that its systematic infill drilling is improving the geological model and confidence in these lenses. In addition to identifying opportunities to expand mineralization, the work by Emperor is intended to support the conversion of portions of the current Inferred Mineral Resource to the Indicated category in the Company’s future NI 43-101 Mineral Resource Estimate update.

Hole DQ26-52, intersected 24.1 m grading 2.6 g/t Au, in close proximity to the previously reported holes DQ26-33, 34, and 35 (see Emperor’s press release dated June 2, 2026). Notably, hole DQ26-34 intersected 9.5 m grading 2.7 g/t Au. The results in DQ26-52 demonstrated increased mineralized thickness while maintaining comparable grades, further supporting the interpretation that these gold-bearing lenses exhibit localized structural thickening. This growing understanding of the deposit geometry reinforces the company’s belief that significant ounces remain to be added within the existing mineralized footprint through systematic infill drilling. By better defining these structurally controlled thickened zones, Emperor Metals believes there is substantial potential to increase future mineral resources without materially expanding the overall deposit footprint.

Emperor continues to receive assay results from the completed 2025/2026 exploration program. Remaining results, including assays from historical core resampling, will be incorporated into the Company’s ongoing geological interpretation and resource modelling. Emperor is also advancing toward a future Preliminary Economic Assessment (PEA) with an updated 43-101 resource for Duquesne West, with the updated geological model expected to help inform the timing of this milestone.
