 Vancouver, British Columbia--(Newsfile Corp. - September 10, 2025) - T2 Metals Corp. (TSXV: TWO) (OTCQB: TWOSF) (WKN: A2DR6E) ("T2 Metals" or the "Company") is   pleased to announce signing of an Option Agreement (the "Option") with   renowned explorer Shawn Ryan ("Ryan") and Wildwood Exploration Inc.   (together with Ryan, the "Optionor") to earn a 100% interest in the 27.4   sq km Shanghai gold-silver project in the Mayo Mining District, Yukon   Territory, Canada.  The project lies within the Tombstone Gold Belt, 12   km west of Hecla Mining's Keno Hill silver mine, and midway between  the  AurMac, Eagle and Raven intrusion-related deposits (see Table 1 for   further information on these deposits).
 
 The Shanghai project includes a Class 3 permit enabling drilling, road construction and installation of a camp.
 
 Highlights:
 
 
 The   Shanghai project 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.Large landholding in the Tombstone Gold Belt, one of North America's premier gold and silver mining districts;Project   lies within 10 km of multiple resource-stage gold projects as reported   within NI43-101 compliant technical reports since 2022 (see resource   information pertaining to the Eagle, Olive, Raven, Airstrip and   Powerline projects in Table 1 and  www.sedarplus.ca for supporting technical reports);Similar geological setting to major discoveries by Sitka Gold Corp and Banyan Gold Corp;No prior exploration drilling on the property;High gold, silver, antimony and bismuth in soil samples provide immediate targets.  Gold values in soil up to 6.1 g/t Au;Permits in place for road construction and drilling;Highly regarded and successful explorer Shawn Ryan to join T2 Metals' Advisory Board; 
 
 Mark Saxon, CEO of T2 Metals Corp., said, "We   have worked hard to identify high potential gold projects to augment   our existing portfolio, and are very pleased to have secured Shanghai in   one of North America's premier gold exploration districts.  The  project  has been held by Shawn Ryan for over 20 years, during which  time major  gold projects have been discovered on the property  boundaries.
 
 New   investment by a range of explorers in the Tombstone Gold Belt is   progressively revealing significant gold deposits. We are very pleased   to join the search, supported by one of the Yukon's most successful   explorers in Shawn Ryan."
 
 Project partner, Shawn Ryan, commented,   "The geology and geochemistry of the Shanghai project look a lot like   that from the surrounding resource-stage gold deposits, and it is a   project well overdue for drilling.  We are keen to see what T2 Metals   will discover and I'm very happy to be advising their technical team."

 The   Shanghai claims cover a large area of Hyland Group metasediments   immediately above the Robert Service Thrust fault with mapped   mid-Cretaceous (~90Ma) Tombstone Plutonic Suite intrusions (Figure 2,   3).  This setting is analogous to the AurMac deposit of Banyan Gold   Corp, which hosts 112.5 million tonnes at 0.63 g/t Au (for 2.28 million   oz of gold) in the Indicated Resource estimate category; and 280.6   million tonnes at 0.60 g/t Au (for 5.50 million ounces of gold) in the   Inferred Resource estimate category, only 6 km to the south of Shanghai   (resource information for the AurMac deposit is based on a technical   report prepared for Banyan Gold Corp titled Technical Report, Aurmac   Property, Yukon Territory, Canada by Hantelmann, T. et al., with an   effective date of June 28, 2025 and available at  www.sedarplus.ca). See Table 1 for additional information.
 
 The   presence of the Tombstone Plutonic Suite is similar to the Yukon's  most  exciting recent discoveries that lie to the east (Snowline) and  west  (Sitka) of Shanghai.
 
 From 2004, Ryan staked the areas  surrounding  the historical Shanghai silver-lead-zinc mine north of  Mayo, identifying  overlapping potential for intrusion-related gold and  high-grade silver.   As the Hyland Group presents limited outcrop, Ryan  applied the  techniques utilised during his discovery of the White Gold  and Coffee  deposits and collected more than 4,000 auger soil samples.   This sample  data has defined areas of high gold-antimony-bismuth, an  association  that correlates well to the intrusion-related gold deposits  being  explored by Banyan Gold Corp, Sitka Gold Corp and Snowline Gold  Corp;  and areas of high silver-lead which correlates to Keno Hill style   mineralization.
 
 Auger soil data covers an area of 23 km2   with gold values ranging from <0.5 ppb to 6.1 ppm averaging 17 ppb;   silver values ranging from <0.05 ppm to >100 ppm averaging 0.4   ppm; and lead ranging from 15 ppm to >1% averaging 27 ppm (4435   samples).   In addition to auger soil sampling, Ryan completed ground   magnetics and induced polarization ("IP") geophysics over much of the   Shanghai property.  The reader is cautioned that while this information   is considered reliable the Qualified Person and the Company have relied   on data provided by the Optionor and has been unable to verify the   information independently.  Additional information as to the history of   the Shanghai project can be found in NI43-101 Technical Report titled   "Shanghai Project Technical Report, Mayo Mining District, Yukon" dated   July 15, 2022 by Doherty, R. A. (P. Geo.) on behalf of Targa Exploration   Corp. on  www.sedarplus.ca.
 
 Despite   the discovery potential of the project, and geological similarity to   major deposits, no exploration drilling has been completed at Shanghai.    T2 Metals proposes additional surface sampling and local geophysics to   better refine and prioritise target areas, followed by drilling during   2026.  The Shanghai project holds a valid Class 3 Quartz Mining Land  Use  permit which enables drilling, road construction and installation  of a  camp if required.  The project lies within 5km of the Eagle Gold  Mine  road and 6 km from Baynan Gold Corp's AurMac camp.

 Option Terms
 
 Subject   to receipt of TSX Venture Exchange ("TSXV") approval of the Option   Agreement, T2 Metals will have the  option to acquire a 100% undivided   interest in the Shanghai project, for a total consideration of $500,000   in cash and 3,000,000 common shares of T2 Metals to be paid to the   Optionor in incremental amounts over a seven-year period, which may be   accelerated at the discretion of T2 Metals. An initial cash payment of   $50,000 and an initial payment of 300,000 common shares in T2 Metals   will be made following TSXV acceptance of the Transaction. All shares   issued under the Option Agreement will be subject to a four-month hold   period from the date of issuance in accordance with applicable   securities laws.
 
 In order to exercise the Option, T2 Metals is   also required to incur exploration expenditures on the Shanghai project   totalling a minimum of $1,800,000 over six years, including $100,000 by   November 15, 2026. Upon commencement of commercial production on the   Shanghai project, the Optionor will retain a 2% net smelter return   royalty on the property with 1% purchasable by T2 Metals for the cash   payment of $1,000,000 to the Optionor.
 
 The claims are located   within the traditional territory of the Nacho Nyak Dun First nation,   which has settled its land claim, and is a self-governing first nation.
 
 About Shawn Ryan
 
 As   part of the Shanghai transaction, Shawn Ryan has agreed to join T2   Metals Advisory Board.  Shawn is a well-known prospector and   entrepreneur in the Yukon's mineral exploration industry. He is   recognized for his innovative and systematic approach to gold   exploration, which has been credited with sparking a "second Klondike   gold rush". Ryan's career is marked by a methodical approach to   sampling, including development of a novel auger soil sampling   technique, a method particularly effective in the Yukon where thick soil   layers often obscure bedrock.
 
 Shawn Ryan's work led to  several  significant discoveries including the Golden Saddle and Arc  deposits,  which became part of the multi-million ounce White Gold  Project acquired  by Kinross Gold, and the Coffee project, which was  sold to Goldcorp  (now Newmont Corporation) for $520 million.  His  contributions to the  industry have earned him numerous awards,  including the Bill Dennis  Award for prospecting from the Prospectors  & Developers Association  of Canada (PDAC). Shawn's work is seen as a  major factor in modernizing  exploration in the Yukon and drawing new  attention to the territory's  mineral potential.

 About the Historic Shanghai Mine
 
 The   Shanghai 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 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.
 
 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.
