T2 METALS PROVIDES EXPLORATION UPDATE AT AURORA PROJECT, YUKON, CANADA

T2 Metals Corp. has provided an update on the exploration program under way at its Aurora gold-silver project in Yukon's Tombstone gold belt, one of North America's most prolific gold regions.

Field crews are well advanced on geological mapping, rock and soil sampling, with mapping successfully discovering new outcrops and rock float bearing semi-massive sulphide mineralization containing chalcopyrite (copper sulphide) and stibnite (antimony sulphide). Furthermore, an airborne lidar (light detection and ranging) survey has been completed, and drill site preparation is under way.

Project location

The Aurora project is located in Yukon's Dawson mining district, one of the territory's most active exploration regions, known for district-scale gold systems, significant discoveries and continuing exploration success. The project covers a large, district-scale land package of 76 square kilometres, first staked by renowned Yukon prospector and explorer Shawn Ryan in 2004.

The project is located only eight kilometres west of Prospector Metals' ML project where recent drilling discovered high grades of copper and gold including 44 metres averaging 13.79 grams per tonne gold and 1.84 per cent copper in hole ML25-31 (see Prospector Metals news release dated Oct. 1, 2025). The Aurora and ML projects share a similar geological setting and discovery potential. Furthermore, Brewery Creek, a past-producing open-pit gold mine lies 30 kilometres south of Aurora.

Aurora has returned high-grade gold from surface sampling and limited historical drilling yet remains largely untested and offers considerable exploration upside.

Exploration program highlights and results

Work completed to date at Aurora forms part of the company's Q3/Q4 2026 multidisciplinary field programs announced on June 30, 2026. Highlights include:

• Airborne lidar (light detection and ranging) survey at 10 pts/square metre sample spacing was completed across the project. When processed, the data will enable refinement of the structural setting of mineralization, highlight intrusion-related targets and facilitate access planning ahead of drilling programs.
• More than 120 rock samples and 3,000 soil samples collected and submitted for assay to date across a 10 km by five km area. The soil/auger sampling program is being led by Callum Ryan, reflecting the prior sampling protocols used by project vendor Shawn Ryan.
• Geological mapping with rock sampling was completed over the highest-priority drill target areas where past work had identified gold, silver and copper mineralization:
  • A new area of semi-massive stibnite mineralization has been discovered in outcrop 300 m from the Antimony Mnt prospect. Assay results are pending;
  • A new area of semi-massive sulphide mineralization where chalcopyrite (visual estimate) exceeds 15 per cent has been discovered in rock float 300 m to the northeast of the Rainbow prospect. Assay results are pending.
• Drill site preparation is under way ahead of the proposed RAB drilling program, scheduled to begin in July/August, 2026.

"Our extensive early summer exploration program is setting us up strongly for further discoveries at Aurora. The new highly mineralized samples highlight the pedigree of this sparsely tested project and provide additional opportunities beyond the known gold mineralization," said Mark Saxon, president and chief executive officer of T2 Metals. "Our field teams have moved quickly through mapping and sampling, and we are now turning that surface work into drill-ready targets. We look forward to receiving assay results from these new discoveries ahead of drill testing later this year."

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 major reduced intrusion-related gold systems (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.

Geological context

The Aurora claims are centred on the Antimony Mountain stock, a Tombstone Plutonic suite intrusion. The intrusion takes its name from the discovery of stibnite (antimony sulphide) veins as early as 1916, and exploration in the area has been intermittent ever since. Shawn Ryan and past explorers have identified eight significant gold-bearing prospects across a 10 km trend on the project using soil and rock chip sampling. Despite its prospectivity, Aurora has seen less than 3,000 m of total drilling and no work has been undertaken for over 15 years prior to T2 Metals' involvement. See news release dated Feb. 26, 2026, for more information.

The newly discovered semi-massive copper and antimony mineralization (visual estimate), associated with arsenopyrite and pyrite, highlights Aurora's exploration potential. This mineralization is consistent with the polymetallic footprint typical of RIRGS in the district, that may include skarn associated massive sulphide. T2 Metals has noted similarities between iron-oxide/jarosite alteration observed at Aurora and at the ML project. Sampling results reinforce the prospectivity of this section of the Dawson mining district and support the company's view that Aurora hosts multiple, potentially related, styles of mineralization warranting drill testing in 2026.

Shawn Ryan, advisory board member of T2 Metals, noted: "I had the opportunity for a site visit to Aurora during the current work programs. While I've spent a lot of time walking this ground in the past, it's highly encouraging to see that new discoveries with high grades and the right alteration styles can still be found. I'm looking forward to seeing this tested with the drill after a very long hiatus."
