T2 METALS COMPLETES AIRBORNE AEROMAGNETIC AND RADIOMETRIC SURVEY AT SHANGHAI PROJECT, YUKON, CANADA

T2 Metals Corp. has completed a helicopter-borne, high-resolution aeromagnetic and radiometric survey over its Shanghai silver-gold project in the Tombstone gold belt, one of North America's most prolific gold regions. The survey provides a new data set to highlight structure and enable the direct identification of intrusive rocks that may be associated with gold and silver mineralization discovered to date.

Project location

The Shanghai project is located in the Yukon's Mayo mining district, a historical and active precious metals region widely known for large-scale gold-silver systems, major discoveries and operating mines. The project is surrounded by multimillion-ounce deposits, including Hecla Mining's Keno Hill mine, one of the world's highest-grade silver deposits, and Banyan Gold's AurMac project, one of Canada's largest unmined gold deposits (see news release dated Sept. 10, 2025, for third party project information).

Despite sharing significant geological similarities to both Keno Hill and AurMac, and hosting high-grade silver-gold mineralization, Shanghai remains largely underexplored and has never been drilled.

Survey highlights

The survey was flown by Precision GeoSurveys of Langley, B.C., and forms part of the company's Q3/Q4 2026 multidisciplinary field program announced on June 30, 2026. Highlights from the survey include:

• Target summary: Shanghai lies three kilometres north of the AurMac deposit and 12 km west of the Keno Hill mine. As the project shares significant geological similarities with the AurMac deposit and Keno Hill mine, it provides a high degree of targeting confidence.
• Survey type: Helicopter-borne, low-level combined aeromagnetic and radiometric (gamma-ray spectrometer) survey.
• Objective: Map buried/blind Tombstone plutonic suite intrusions and associated hornfels/alteration footprints with potential to be mineralized.
• Coverage: Approximately 31 square kilometres/425 line km across the Shanghai project and surrounding areas.
• Instrumentation: Nose-mounted cesium vapor magnetometer (less than 0.01 nT sensitivity); 21-litre, 512-channel NaI(Tl) gamma-ray spectrometer.
• Status: Precision GeoSurveys is now finalizing magnetic and radiometric corrections and maps, with results expected within approximately two weeks.

Mark Saxon, president and chief executive officer of T2 Metals, commented: "This airborne survey provides us with a district-scale view of Shanghai for the first time. High-resolution magnetics with radiometrics is a proven approach for tracing Tombstone Plutonic suite intrusions and their alteration halos through this terrain. Combined with the existing soil and rock results, this data set sharpens our RAB and diamond drill targeting ahead of drilling later this season. We look forward to sharing the interpreted results and targets with shareholders shortly."

Survey rationale

The survey was designed to trace the subsurface extent of the mid-Cretaceous Tombstone Plutonic suite -- the reduced, felsic intrusions responsible for reduced intrusion-related gold systems (RIRGS) throughout the belt. Magnetic data will help define the geometry, depth, and structural setting of buried or blind intrusive bodies, while radiometric data, particularly the potassium response, is expected to highlight the hornfels and hydrothermal alteration halos that typically envelope these systems and their associated gold mineralization.

Results will be integrated with the company's existing soil and rock geochemistry, geological mapping, and lidar (light detection and ranging) data sets to refine drill targets. The project is prospective for both RIRGS and Keno Hill-style Ag-Pb-Zn (silver-lead-zinc) veins, with evidence for both styles identified within existing data sets.

A total of 425 line kilometres was flown across the Shanghai project and surrounding areas, covering approximately 31 square km. The area was flown at a line spacing of 100 metres on a north-south orientation, with perpendicular tie lines flown at a ratio of one tie line for every 10 survey lines. Surveying was flown at a nominal terrain clearance of 40 metres to maximize resolution. The survey simultaneously acquired high-resolution magnetic data using a nose-mounted cesium vapor magnetometer (sensitivity better than 0.01 nT) and radiometric (potassium, uranium, thorium) data using a 21-litre, 512-channel gamma-ray spectrometer carried internal to the aircraft.

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 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 RIRGS. Exploration efforts have identified that gold is often hosted in sheeted quartz veins and as 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.
