T2 Metals begins fieldwork at Shanghai project

Mr. Mark Saxon reports T2 METALS COMMENCES EXPLORATION AT SHANGHAI GOLD-SILVER PROJECT IN YUKON'S TOMBSTONE GOLD BELT T2 Metals Corp. has commenced fieldwork at the Shanghai gold-silver project in the Mayo mining district, Yukon, Canada. Shanghai covers 27.4 square kilometres (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 northwestern 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. Highlights: Proximity of Shanghai to infrastructure and competitor gold/silver projects has enabled a rapid start to fieldwork; High-grade gold and silver values (1.1 ounces per ton (oz/t) gold (Au) and 790.5 oz/t silver (Ag)) reported from historical trenches to be followed up immediately; Location of these trenches can now accurately be determined with modern lidar (light detection and ranging) 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 and base metal veins of Keno Hill style (see T2 Metals' news release dated Sept. 10, 2025). Shanghai lies only six km from Banyan Gold'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-zinc-lead-gold (Ag-Zn-Pb-Au) mineralization was developed underground in the 1960s by Silver Titan Mines; Zone 2: areas with multielement 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, including 9.1 metres (m) at 1,182.8 grams per tonne (g/t) Ag, 8.2 per cent Pb and 7.2 per cent 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 Mr. Ryan. Sampling reports from these trenches (see Yukon Minfile No. 105M027 and Minfile No. 105M028) describe highly fractured quartz veins and reported grab samples, which contained 1.1 oz/t Au, 790.5 oz/t Ag, 0.4 per cent Pb and 10.4 per cent copper (Cu), associated with a halo of chlorite alteration (see Yukon Minfile No. ARMC005629 and R.A. Doherty, 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. These reported samples and observations, in combination with high values of Ag, Au, Zn and Pb in more regional soil samples, suggest potential for Keno Hill-style polymetallic mineralization The zone 2 target is located within the Upper Proterozoic Hyland Group Yusezyu formation, comprising phyllite and rare calc silicate rocks, which sits above the Roberts Service thrust fault in a setting analogous to Banyan Gold's AurMac deposit. Exploration in this area will focus on broad areas where prior soil samples by Mr. 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. This association of Au-Sb-As and the presence of Tombstone intrusions are commonly observed at other intrusion-related gold deposits, including those also being explored by Sitka Gold and Snowline Gold. Mark Saxon, chief executive officer of T2 Metals, said: "Shanghai is close 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 1960s, 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 at 1,182.8 g/t Ag, 8.2 per cent Pb and 7.2 per cent 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 Yukon, with a range of 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. Gold mineralization in the Tombstone gold belt is typically associated with a distinctive multielement 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, Banyan Gold and Sitka Gold.
