Transition Metals Identifies Four New Polymetallic Showings at Pike Warden, Yukon, Including Samples Returning >10,000 ppm Silver and 3.4% Molybdenum

Rhea-AI Summary

Transition Metals (OTC:TNTMF) reported results from 64 rock and float samples collected at the Pike Warden project, Yukon, on October 14, 2025. Four new polymetallic showings — Apollo, Typhon, Signal, and Bork — were identified with highlight assays including >10,000 ppm Ag, 2.8 g/t Au, 1.9% Cu, 3.41% Mo and 4.31% Pb.

The sampling complemented a summer IP survey and refined drill targets; two drill holes were completed in Copper Junction with core shipped to Whitehorse for logging and assays pending. QA/QC and ALS lab methods are described; grab samples are selective and over-limit values were re-tested using ore-grade methods.

Sudbury, Ontario--(Newsfile Corp. - October 14, 2025) - Transition Metals Corp. (TSXV: XTM) ("Transition" or "the Company") is pleased to report 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 September 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 (Figure 1).

Scott McLean, P.Geo., CEO of Transition Metals, commented, "The results from our summer sampling work continue to expand our property scale datasets towards vectoring within this large and prospective geodynamic setting. This work has helped us advance targets to the drill-ready stage, particularly at 3 of 5 large system scale target areas."

Rock and soil sampling results highlight areas of elevated base and/or precious metal mineralization. The new showings are indicated with a green star.

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 (4) samples returned values higher than 0.2 ppm gold (Au), three (3) samples returned values higher than 100 ppm silver (Ag), three (3) samples returned values higher than 0.1% copper (Cu), four (4) samples returned values higher than 1,000 ppm molybdenum (Mo), and two (2) samples returning values greater than 1% lead (Pb). A selection of highlight values from the summer sampling actives are presented below in Table 1.

Table 1: Highlight Results from Summer Sampling Program

Target Area	Showing	Sample	Sample Type*	Au (g/t)	Ag (g/t)	Cu %	Mo %	Pb %
Olympus	Apollo	E811857	Float	2.8	16.8	0.01	0.03	0.03
Olympus	Artemis	E811853	Float	0.2	183.0	0.15	0.00	4.31

Copper Junction	Whistle	E811893	Grab	1.0	6.4	0.00	0.00	0.01
Copper Junction	Silver Train	K665109	Float	0.1	409.0	1.90	0.00	0.00
Copper Junction	Signal	E811877	Float	0.0	13.7	0.08	0.23	0.00
Copper Junction	Bork	E811891	Float	0.0	0.5	0.01	0.23	0.00
ERT	ERT Zone	E811860	Float	2.0	>10,000*	0.59	0.00	3.04

* Note: Grab samples of rock (bedrock and float/scree) are selective by nature, and the values reported do not provide direct evidence for the extent or continuity of mineralization. Values stated as >10,000 ppm are over-limit results, which in and of themselves were over-range ore-grade results determined by ore-grade methods.

Drilling Update

Previously Transition announced the initiation of a drill program (Photo 1) at Pike Warden, testing accessible target zones within the Copper Junction area of the Pike Warden Project (see news release dated October 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 over-limit 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 (Figure 1) 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 centers in Canada.

The property is located approximately 65 kilometres southwest of Whitehorse, Yukon, and is composed of 203 contiguous mining claims totaling approximately 41 km². 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% interest in the property from the Vendor in exchange for cash, shares, and work expenditures over a four-year period.
