Cantex Mine Development Corp Provides Update On Metallurgical Test Work Program Cantex Mine Development Corp. started the metallurgical program in January 2026, which was designed to evaluate pre-concentration by X-Ray Transmission sorting, mineralogy, comminution characteristics, etc. for three composites that cover different mineralization types in the deposit. The three composites were selected to represent the range of mineralization styles seen across both the strike length and depth extent of the mineralization. The composites consist of half split HQ drill core. Oxide Composite. High Grade Sulphide Composite. Low Grade Sulphide Composite. The testwork program was split into 2 components: sorting test work to identify opportunities to pre-concentrate mill feed, conducted at Base Met Labs, and the conventional processing testwork conducted at ALS Kamloops Metallurgy, an independent metallurgical laboratory specializing in base and precious metal process development. Sorting amenability was carried out on a sample of 100 pieces of drill core which covered a range of lead, zinc, silver, and sulphur grades and included samples from all 3 zone types currently under testing. The results confirmed excellent differentiation between mineralization-rich rock and barren host rock, achieving strong pre-concentration performance across the tested size fractions. Core samples from multiple mineralized zones were subjected to sensor-based sorting using X-ray transmission (XRT) technology. XRT is a technology that differentiates rocks based on atomic density. As such, it is able to discern dense silver-lead-zinc-germanium bearing rocks from lighter unmineralized country rock. In this test, the individual pieces of drill core measured approximately 10cm in length. The curve demonstrates that 95.0%, 97.8%, and 97.9% of the silver, zinc, and lead report to a concentrate stream containing 70% of the mass. Announcement • Jan 29
Cantex Mine Development Corp. Commences Metallurgical Study, Plan for 2026 Drilling At North Rackla Projects in Yukon, Canada Cantex Mine Development Corp. provided a summary of its 2025 program on its 100%-owned 14,077 hectare North Rackla claim block in the Yukon. Cantex has commenced a metallurgical test work program on its Massive Sulphide project. The Company has engaged JDS Energy and Mining Inc. to manage the metallurgical testwork program under the supervision of senior metallurgist Shane Tad Crowie, PEng. Drilling at the Massive Sulphide project continues to extend the strike length of the mineralization. Just before the end of the 2025 drill season the first of a series of holes was completed to test a 150m step out of the mineralization to the northeast. This hole, testing the shallow portion of the strike, successfully intersected sulphide mineralization. Samples on the mineralization have been submitted to test their germanium content. Additional deeper drilling from this pad is planned for the start of the upcoming season. The drill has been winterized and remains on the pad for this work. Results for this drilling are awaited. Copper Project: The Copper Project was discovered by prospecting a soil-talus anomaly on the western side of the North Rackla property. Initial drilling intersected 2.5 metres of 3.93% copper including 1 metre of 7.32% copper. This was followed up with drilling early in the 2024 field season where results included 2.9 metres of 4.54% copper in hole YKDD24-287. Drilling in 2025 was designed to test for significant strike extensions to the previously discovered mineralization. Several anomalies detected by a ground geophysical induced polarization/conductivity survey were tested. Significant copper mineralization has not yet been intersected. Regional Anomalies in North Rackla: During the 2025 field season work was conducted on several other areas within the claim block. This included the start to drill testing at the B43 base metal anomaly. Grab samples previously collected while prospecting the B43 anomaly. Three holes were drilled before the end of the season. Results for these holes are awaited. The 2026 drill program will have two main priorities. The first is to continue extending the strike length of the Main Zone mineralization. The second is to test a number of new targets within the North Rackla claim block. Rock samples collected at surface have shown elevated gold, silver, copper, lead and zinc values. A new, lightweight, heli-portable drill rig is being constructed to be used for the regional target testing. This drill is to be ready for the start of the drill season. Summary: Cantex looks forward to a productive drill season on its North Rackla project. Work will be undertaken not only on the advanced Massive Sulphide Project but also selected targets within the broader claim block. The high silver price is significant for Main Zone, which contains up to 232 g/t silver and GZ Zone, which contains up to 363 g/t silver. Several areas within Cantex's large 15km by 15km North Rackla claim block contain highly anomalous surficial gold mineralization. It is hoped that Cantex will be able to extend this mineralization to depth with the newly constructed drill. Sample Preparation, QA and QC: The rock and soil–talus samples are sent to C.F. Mineral Research Ltd., an ISO 9001 accredited laboratory owned by Dr. Charles Fipke, where they are pulverized and prepared for analysis including the insertion of standards. ALS Chemex in Vancouver analyzed the samples using a four–acid digestion with an ICP–MS finish. The 48 element ME–MS61 technique was used to provide a geochemical signature of the mineralization. Where lead, zinc or copper values exceeded one percent the Pb–OG62, Zn–OG62 or Cu–OG62 techniques were used. These have upper limits of 20% lead, 30% zinc and 50% copper, respectively. Samples with lead and zinc values over these limits were then analyzed by titration methods Pb–VOL70 and Zn–VOL50. Where silver samples exceeded 100 g/t the Ag–OG62 technique was used which has an upper limit of 1,500 g/t. Where silver values exceeded 1,500 g/t the Ag-GRA22 technique was used.
