T2 METALS COMMENCES EXPLORATION AT SHANGHAI GOLD-SILVER PROJECT IN
YUKON’S TOMBSTONE GOLD BELT
Immediate Follow Up of Highest Priority Gold and Silver Targets
Vancouver, British Columbia – September 24 2025: T2 Metals Corp. (“T2 Metals” or the “Company”)
(TSX-V: TWO) (OTCQB: TWOSF) (WKN: A2DR6E) is pleased to announce commencement of fieldwork at the
Shanghai gold-silver project in the Mayo Mining District, Yukon Territory, Canada. Shanghai covers 27.4 sq km, lies
12 km west of Hecla Mining’s Keno Hill silver mine, and is midway between the AurMac, Eagle and Raven intrusion-
related gold deposits.
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 (Figure 1). 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.
Highlights:
• Proximity of Shanghai to infrastructure and competitor gold/silver projects has enabled a rapid start
to field work;
• High grade gold and silver values (1.1 oz/tonne Au, 790.5 oz/tonne Ag) reported from historical
trenches to be followed up immediately. Location of these trenches can now accurately be determined
with modern LiDAR data;
• Project is undrilled despite sitting within multiple sites of exploration, resource estimation and mining
by peer companies;
• Class 3 permit in place that enables immediate drilling, access construction and camp establishment;
• Project held by T2 Metals under option with highly regarded explorer Shawn Ryan;
This first field program by T2 Metals will comprise a helicopter-supported team to collect rock chip and soil samples
in the vicinity of geochemical anomalies discovered by previous soil and rock sampling campaigns. Furthermore,
the team will field check and sample historical workings which targeted high-grade silver-base metal veins of Keno
Hill style (see T2 Metals’ press release dated September 10, 2025). Shanghai lies only 6 km from Banyan Gold
Corp’s AurMac camp and 35 km from the Mayo airfield, making helicopter support from either location very efficient.
Fieldwork will focus on two distinct areas and target styles:
• Zone 1: the area covering and surrounding the historical Shanghai Silver Mine where Keno Hill – style
silver (“Ag”) - zinc (“Zn”) - lead (“Pb”) - gold (“Au”) mineralization was developed underground in the 1960s
by Silver Titan Mines; and
• Zone 2: areas with multi-element and gold soil anomalism that suggest the presence of intrusion related
Au mineralization.
The Zone 1 target covers 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. Exploration by Silver Titan Mines Ltd at the
Shanghai Silver Mine reported high silver grades from underground workings that followed veins includ ing 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).

Trenches dug between 1960 and 1966 by Silver Titan Mines Ltd along strike from the Shanghai Silver Mine have
been located utilizing an airborne LiDAR survey carried out by project partner Shawn Ryan ( Figure 3). Sampling
reports from these trenches (see Yukon Minfile #105M027 and Minfile #105M028) describe highly fractured quartz
veins and reported grab samples which contained 1.1 oz/t Au, 790.5 oz/t Ag, 0.4% Pb, and 10.4% Cu
associated with a halo of chlorite alteration (see Yukon Minfile #ARMC005629 and Doherty, R. A. 2022)*1.
Additional historical trenching has been identified using LiDAR at the Titan prospect, which lies 5.5km from the
Shanghai Silver Mine in a similar setting associated with northeast trending faults beneath the Robert Service Thrust
Fault (see Figure 3).
These reported samples and observations, in combination with high values of Ag, Au, Zn, and Pb in more regional
soil samples, suggests potential for Keno Hill – style polymetallic mineralization (Figure 2).

See Table 1 for additional information on resource-stage projects and supporting NI43-101 report references.
The Zone 2 target is located 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. Exploration in this area will focus on broad areas where prior soil samples by partner Shawn
Ryan discovered anomalous gold, antimony (“Sb”), and arsenic (“As”) that are coincident with Late Cretaceous age
quartz monzonite / granodiorite intrusions, referred to as “Tombstone Intrusions” ( Figure 4). This association of
Au-Sb-As and the presence of Tombstone Intrusions is commonly observed at other intrusion-related gold deposits
including those also being explored by Sitka Gold Corp and Snowline Gold Corp.

Mark Saxon, CEO of T2 Metals Corp. said " Shanghai is clo se to major gold projects which delivers both high
prospectivity and simplified logistics . We have managed to hit the ground running utilizing local helicopter and
camp facilities to follow up existing targets. The work history on the Shanghai project is limited considering its
geological potential, due to private ownership by Shawn Ryan for more than 20 years. It is exciting to have the
opportunity to draw together historic trench sampling that discovered high grade gold and silver, with modern
LiDAR, to identify new undrilled targets.”

About the Historical Shanghai Silver Mine
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 Intrusion-Related Gold
Systems (IRGS). 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.
5
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 dis coveries by companies such as Snowline Gold Corp. , Banyan Gold
Corp. and Sitka Gold Corp.
