T2 Metals Completes First Field Program at the Shanghai Gold-Silver Project, Yukon

Geological Mapping Identifies Two Distinct High-Priority Target Styles

T2 Metals Corp. (TSXV: TWO,OTC:TWOSF) (OTCQB: TWOSF) (WKN: A3DVMD) ("T2 Metals" or the "Company") is pleased to announce the completion of the Company's first reconnaissance exploration program at the Shanghai gold - silver Project (the "Project") in the prolific Tombstone Gold Belt of the Yukon Territory, Canada (Figure 1). T2 Metals is earning a 100% interest in the 27.4 sq km project from renowned explorer Shawn Ryan (see press release dated September 10 2025).

The helicopter-supported field program was executed by a four-person crew from Groundtruth Exploration Inc., utilizing the nearby Banyan Gold Corp camp as an operational base. The campaign successfully completed the primary objective of ground checking gold and silver auger soil geochemical anomalies with the goal of defining drilling targets for 2026.

The Shanghai Project has been issued a Class 3 permit that enables drilling, road construction and installation of a camp with no additional permission required. The historical Shanghai Silver Mine had road access from the Eagle Mine Road at the time of production. Despite its proximity to gold ("Au") and silver ("Ag") deposits and mines, the Shanghai project has never been drilled.

Program Summary & Highlights:

• Targeted Sampling: team successfully collected a total of 52 rock and 3 soil samples from two main prospective zones, focusing on areas with significant gold and silver anomalies in soils and high-grade trench samples.

• Target Zone 1 (Ag-Au-Polymetallic): prospecting in the southern sector confirmed the presence of Keno Hill-style, polymetallic quartz-vein mineralization within weathered metasediments (interpreted as Keno Hill Quartzite). Mapping revealed sulphides and sulfosalts - key indicators of polymetallic vein systems in the Keno Hill area 12 km east of Shanghai.
  
  Prior sampling from historical trenches in this area included the exceptional results of 1.1 oz/tonne Au and 790.5 oz/tonne Ag (see Yukon Minfile #ARMC005629 and Doherty, R. A. 2022)*¹

• Target Zone 2 (Reduced Intrusion-Related Gold Systems or "RIRGS"): prospecting in the northern sector located a deformed rock sequence consisting of layered mica schist/phyllite of the Upper Proterozoic Yusezyu Formation with iron-oxide alteration. This is strongly indicative of a disseminated mineralization of a RIRGS type, often associated with nearby Cretaceous intrusions.
  
  Site visits included the location of a 6.1 g/t Au soil sample previously taken by project partner Shawn Ryan.

• Logistics: The program was executed efficiently by a geological team, with logistical access from the Banyan Gold Corp camp only 6 km from site. All rock and soil samples have been delivered to Bureau Veritas Minerals laboratory in Whitehorse, Yukon for analysis.

Mark Saxon, CEO of T2 Metals Corp commented, "This high-impact program was executed by the experienced team from Groundtruth Exploration and provided rapid validation of auger soil anomalies identified by Shawn Ryan. We have now geologically confirmed two distinct styles of mineralization on the Shanghai property: Keno Hill-style silver veins and the large-scale Reduced Intrusion-Related Gold style, similar to those being explored and developed by peers in the Tombstone Gold Belt. We keenly await this program's assay results to finalize and prioritize drill locations for the Phase 1 drill campaign planned for 2026."

Assessment of two distinct mineralization targets

The Zone 1 (Figure 2) sampling targeted the Keno Hill Quartzite that lies immediately beneath the Robert Service Thrust Fault, in a geological setting that matches that of the nearby Keno Hill mines (Figure 3). Mapping located quartz veins and stockworks within weathered metasediments (shale/schist) (Figure 4A & B). The coarse-grained, layered quartz veins with sulphosalts (common silver carriers in the district) are direct analogs to Keno Hill-style mineralization. Numerous samples were collected.

The Zone 2 (Figure 2) sampling focused on locations within the Upper Proterozoic Hyland Group Yusezyu Formation comprised of phyllite and rare calc silicate rocks that sits above the Roberts Service Thrust Fault in a setting analogous to Banyan Gold Corp's AurMac deposit (Figure 5). Exploration in this area focused on broad areas where prior soil samples by partner Shawn Ryan discovered anomalous gold, antimony, and arsenic anomalies.

The field team noted significant structural deformation in outcrop likely due to the close proximity to the Robert Service Thrust Fault. Furthermore, quartz veining combined with iron-oxide alteration was commonly observed (Figure 5), suggesting fluid flow related to nearby Cretaceous intrusions and the potential for a disseminated, intrusion-related gold system. The site of a prior 6.141 g/t Au auger soil sample was located and sampled.

Access alternatives for 2026 drill programs were assessed.

About the Historical Shanghai Silver Mine

Shanghai sits within the northwest portion of the Yukon's Tombstone Gold Belt, one of North America's most active and gold-endowed mining districts, and home to the famous Klondike goldfield. Recent exploration of the Tombstone Gold Belt by Snowline Gold Corp (Valley project), Sitka Gold Corp (RC Gold project), Banyan Gold Corp (AurMac project) and Sanatana Resources Inc have highlighted the potential for major new gold discoveries and value creation.

The Shanghai Silver Mine is hosted by the Keno Hill Quartzite immediately below the regionally extensive Robert Service Thrust fault. It lies on the northern limb of the McQuesten Antiform, presenting a mirror image of the Keno Hill camp found on the southern limb of this antiform.

During the 1960's the Shanghai Silver Mine was explored by Silver Titan Mines Ltd with close to 800 m of underground development. Assays reported from underground workings that followed veins included 9.1 m @ 1182.8 g/t Ag, 8.2% Pb and 7.2% Zn (average width of 1.5 m) (Yukon Minfile 105M 028).

About the Tombstone Gold Belt

The Tombstone Gold Belt, a component of the larger Tintina Gold Province, is a highly prospective metallogenic province in the Yukon, with a range of well-known and emerging gold discoveries. The belt is characterized by a suite of mid-Cretaceous, reduced, felsic intrusions known as the Tombstone Plutonic Suite. These intrusive bodies and the surrounding host rocks have created conditions for the formation of numerous Reduced Intrusion-Related Gold Systems (RIRGS). Exploration efforts have identified multiple mineralized corridors with gold hosted in sheeted quartz veins and disseminated mineralization within both the intrusive bodies and the hornfelsed country rocks.

Gold mineralization in the Tombstone Gold Belt is typically associated with a distinctive multi-element signature that includes bismuth, tellurium, and tungsten, along with arsenic and antimony. Gold-bearing fluids exsolved from cooling intrusions and preferentially deposited gold in brittle, structurally controlled environments. Both high-grade, structurally-controlled vein systems and lower-grade, bulk-tonnage deposits are known. The region hosts numerous significant deposits and is the site of recent discoveries by companies such as Snowline Gold Corp., Banyan Gold Corp. and Sitka Gold Corp.
