TRANSITION METALS IDENTIFIES FOUR NEW POLYMETALLIC SHOWINGS AT PIKE WARDEN, YUKON, INCLUDING SAMPLES RETURNING >10,000 PPM SILVER AND 3.4% MOLYBDENUM

Transition Metals Corp. has released assay results from the summer sampling activities at its Pike Warden project, located near Whitehorse, Yukon. These samples were collected in conjunction with an induced polarization (IP) geophysical survey conducted over accessible portions of the Copper North and Copper Junction target areas (see news release dated Sept. 9, 2025). The program aimed to broaden the project's geochemical coverage across multiple high-priority target areas, including Olympus, Copper Junction, Copper North, ERT and peripheral targets to the IP survey area.

• Four new showings identified: Apollo, Typhon, Signal and Bork;
• Select highlight assay values from different samples range up to greater than 10,000 parts per million Ag (silver), 2.8 g/t (grams per tonne) Au (gold), 1.9 per cent Cu (copper), 3.41 per cent Mo (molybdenum) and 4.31 per cent Pb (lead);
• Results from summer sampling refine target areas in connection with the summer IP survey program.

Scott McLean, PGeo, chief executive officer of Transition Metals, commented: "The results from our summer sampling work continue to expand our property scale data sets towards vectoring within this large and prospective geodynamic setting. This work has helped us advance targets to the drill-ready stage, particularly at three of five large system-scale target areas."

Discussion of results

In total, 64 grab samples of bedrock and float material were collected and submitted for analysis, resulting in the discovery of four new polymetallic showings across both the Olympus and Copper Junction target areas: Apollo, Typhon, Signal and Bork. A brief synopsis of sampling results are: four samples returned values higher than 0.2 ppm gold (Au), three samples returned values higher than 100 ppm silver (Ag), three samples returned values higher than 0.1 per cent copper (Cu), four samples returned values higher than 1,000 ppm molybdenum and two samples returning values greater than 1 per cent lead. A selection of highlight values from the summer sampling actives are presented in Table 1.

Drilling update

Previously Transition announced the initiation of a drill program at Pike Warden, testing accessible target zones within the Copper Junction area of the Pike Warden project (see news release dated Oct. 6, 2025). Despite seasonal challenges, the company is pleased to report it has successfully completed two drill holes. The drill and all auxiliary equipment have been demobilized from the property, and all impacted sites have been remediated in full compliance with permit requirements prior to the onset of winter conditions, including the reduced visibility and challenging weather typical of mountain environments.

Drill core has been transported to Whitehorse for detailed geological logging and sampling. Geochemical and assay analyses will be completed in due course, with results to be released once available. Transition extends thanks to Platinum Diamond Drilling Inc., Archer Cathro (1981) Ltd. and Capital Helicopters for their support in executing a safe and efficient drill program late in the season.

Quality assurance/quality control

Transition Metals adheres to sampling and analytical protocols that meet or exceed industry standards. Samples are securely stored until they are transported in batches to the ALS Geochemistry facility in Whitehorse, Yukon. Each sample batch includes certified reference materials, blanks and duplicates, all processed under the control of ALS. The samples were analyzed in Vancouver by ALS Chemex, with ALS Laboratories' quality system meeting the requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015. The analysis was conducted using the ME-MS61 method, which reports 48 elements through four-acid digestion followed by ICP-MS. Gold was analyzed using the AU-ICP21 method, involving fire assay fusion with an ICP-AES finish. In cases of overlimit results, gold was determined by fire assay with a gravimetric finish, and base metals were analyzed using ore-grade (OG62) four-acid digestion with an ICP-AES finish.

About the Pike Warden property

The Pike Warden property is in the traditional territory of Carcross/Tagish First Nation and is situated on the northern rim of the Bennett Lake Caldera complex, one of the largest extinct volcanic centres in Canada.

The property is located approximately 65 kilometres southwest of Whitehorse, Yukon, and is composed of 203 contiguous mining claims totalling approximately 41 square kilometres. The property encompasses a combination of historic and recently discovered high-grade polymetallic gold, copper and silver epithermal showings that are indicative of a large epithermal-porphyry system in the vicinity of the Bennett Lake Volcanic complex. In June, 2022, Transition entered into an option agreement to acquire a 100-per-cent interest in the property from the vendor in exchange for cash, shares and work expenditures over a four-year period.
