Cantex talks plans for 2026 drilling at North Rackla

Executive Summary

• Cantex Mine Development Corp. provided an update on its 2025 exploration program at the 100%-owned North Rackla project in Yukon, Canada, highlighting the commencement of a metallurgical study and ongoing drilling activities.
• At the Massive Sulphide project, drilling successfully intersected sulphide mineralization in a 150-metre stepout to the northeast, with samples submitted for germanium testing; additional deeper drilling is planned for the upcoming season.
• The company outlined its 2026 drill program priorities, which include extending the strike length of the Main zone mineralization and testing new regional targets using a new lightweight, heli-portable drill rig.

Key Details

• Metallurgical Study: Cantex has engaged JDS Energy and Mining Inc. to manage the metallurgical testwork program under the supervision of senior metallurgist Shane Tad Crowie, PEng.
• Massive Sulphide Project Drilling:
  • A hole completed just before the end of the 2025 drill season tested a 150-metre stepout of mineralization to the northeast.
  • The hole successfully intersected sulphide mineralization in the shallow portion of the strike.
  • Samples have been submitted to test for germanium content.
  • The drill has been winterized and remains on the pad for planned additional deeper drilling at the start of the next season.
  • Specific assay results for this hole are awaited.
• Copper Project:
  • Discovered via soil-talus anomaly on the western side of the property.
  • Historical results include 2.5m of 3.93% Cu (including 1m of 7.32% Cu) from April 2023 and 2.9m of 4.54% Cu from hole YKDD24-287 (August 2024).
  • 2025 drilling targeted strike extensions based on ground geophysical IP/conductivity surveys.
  • Significant copper mineralization has not yet been intersected in the 2025 program.
• Regional Anomalies (B43):
  • Drill testing commenced at the B43 base metal anomaly.
  • Three holes were drilled before the end of the season; results are awaited.
  • Previous grab samples from prospecting (June 2021) are referenced in an attached table.
• 2026 Drill Program Priorities:
  • Continue extending the strike length of the Main zone mineralization.
  • Test new targets within the North Rackla claim block.
  • Utilization of a new, lightweight, heli-portable drill rig for regional target testing, expected to be ready for the start of the drill season.
• Market Context & Historical Grades:
  • Management noted a dramatic increase in silver and gold prices.
  • Main zone contains up to 232 g/t silver (per Nov 5, 2019 release).
  • GZ zone contains up to 363 g/t silver (per Feb 16, 2022 release).
  • Several areas within the 15km x 15km claim block show highly anomalous surficial gold mineralization.
• Technical & QA/QC:
  • Sample preparation conducted by C.F. Mineral Research Ltd. (ISO 9001-accredited, owned by Dr. Fipke).
  • Analysis performed by ALS Chemex in Vancouver using four-acid digestion with ICP-MS finish (48-element ME-MS61 technique).
  • Specific techniques used for high-grade elements: Pb-OG62, Zn-OG62, Cu-OG62 (for >1% values), Pb-VOL70, Zn-VOL50 (titration for high limits), Ag-OG62 (for >100 g/t Ag), and Ag-GRA22 (for >1,500 g/t Ag).
