GT Resources - Copper - Palladium - Platinum ("PGE") Project Updates

Toronto, Ontario--(Newsfile Corp. - June 12, 2025) - GT Resources Inc. (TSXV: GT) (OTCQB: CGTRF) (FSE: 7N1) (the "Company" or "GT") is pleased to provide an update with regard to plans for the North Rock Project (Canada) and The Läntinen Koillismaa ("LK") Project (Finland) both Copper-Palladium-Platinum projects.

Highlights

North Rock Copper - Palladium - Platinum ("PGE") Project, Ontario, Canada

• The 2024 exploration program identified off hole geophysical conductors adjacent to historic high-grade footwall vein intercepts which returned up to 14.6 g/t Palladium, 0.5 g/t Platinum, 0.3 g/t Gold and 2.3% Copper, and 0.6% Nickel over 0.6 meters in NR07-062 (see January 27, 2025 news release)

• Upcoming exploration programs include additional Bore Hole Electro Magnetic ("BHEM") surveys of more historic holes, followed by detailed drill plans to target high-grade massive sulphide footwall style copper-palladium rich veins.

LK PGE - Copper - Nickel Project, Finland

LK is the Company's most advanced project with a substantial Palladium-Platinum-Copper rich open pit resource (see April 25, 2022 news release)

• Indicated Resources:

  • 1.1 Million ounces Total Precious Metals (Palladium + Platinum + Gold) ("TMP") (0.89 g/t),

  • 111 Million pounds of Copper (0.13%),

  • 92 Million pounds of Nickel (0.11%), and

  • contained in 38.2 million tonnes.

• Inferred Resources:

  • 1.1 Million ounces TMP (0.68 g/t),

  • 173 Million Pounds Copper (0.16%),

  • 152 Million Pounds Nickel (0.14%), and

  • contained in 49.7 million tonnes.

• LK project remains wide open for expansion, notably along the 17 km long Haukiaho Trend (see July 20, 2022 news release)

Neil Pettigrew, Vice President Exploration, commented "With a significant mineral endowment, LK is the Company's most advanced project and is well position as a source of critical minerals for the European Union.

At North Rock high-grade copper-palladium-rich footwall style veins were not targeted by prior operators who focused on broader zones of disseminated copper-rich gabbro hosted mineralization. We believe there is substantial potential for high-grade footwall style mineralization, and this will be a core focus of future exploration programs."

North Rock Copper - Palladium - Platinum ("PGE") Project, Ontario Canada

The North Rock project is located in Northwest Ontario, boasts excellent infrastructure (bisected by a paved provincial highway and a railroad) and is crossed by power lines. The mineralization consists of copper-rich magmatic sulphide, along a 13-kilometer basal contact of mafic and ultramafic volcanic rocks (Figure 1). The mineralization occurs in two main styles; a more copper-rich "gabbro hosted" disseminated to locally net-textured sulphide within the basal heterolithic, varitextured gabbro, and as massive copper-palladium-rich sulphide "footwall vein" style within the footwall volcanic rocks.

Two very shallow zones have been discovered to date, the most significant of which is the Beaver Pond Zone (Figure 1), which hosts a Historic Resource Estimate¹ of 1 million tons grading 1.2% Copper. The Beaver Pond Zone was discovered by Noranda in 1958 and subsequently explored from underground via a 90-meter deep shaft and one drift on the 70m level.

The Company undertook a BHEM survey in Q4 2024 on select historic holes located within the Beaver Pond zone. This was the first BHEM survey conducted on the property and was a "test case" to see if the North Rock mineralization was amenable to BHEM techniques. A prime focus of the survey was hole NR07-062, which at 780 meters is by far the deepest hole drilled on the project. This hole returned several conductors which have been modelled as Maxwell EM plates (Figure 2) with some plates corresponding to known footwall style copper-palladium-rich mineralization. The survey identified both "in hole" and "off hole" conductors potentially representing untested footwall style mineralization.

Future exploration plans include opening up historic drill trails to provide better access historic holes for more extensive BHEM surveys, including the East Zone (Figure 1) where abundant footwall vein style mineralization has been intersected. This initial phase would be followed by diamond drilling.

LK PGE - Copper - Nickel Project, Finland

The LK Project, located in central Finland represents the Company's most advanced project with a significant NI 43-101 compliant open pit resource (Table 1a & 1b) and is well position to supply the European Union with critical minerals, notably copper, palladium and platinum, of which Europe is heavy dependant on imports with only one producing mine (Boliden's Kevitsa mine in Finland). Boliden also operates both copper and nickel smelters in Finland, thereby providing LK a potential competitive advantage.

The 17-kilometer long Haukiaho trend represents the nearest term expansion potential (Figure 3). The Haukiaho Deposit currently occupies only 2 kilometers of this trend. Historic drilling along this trend, primarily by Outokumpu in the 1960's was only sampled for copper and nickel, partial resampling of historic drill core by the Company in 2022 (see July 20, 2022 news release) returned significant platinum and palladium grades.

Mineral Resource Estimate:

Table 1a. 2022 LK MRE

Table 1b: 2022 LK MRE In-situ contained metal

The Mineral Resource Estimate was prepared by the Company under the supervision of Mr. Sean Horan, P.Geo., Technical Manager of Geology at SLR Consulting Ltd., based in Toronto, Ontario, Canada. Mr. Horan is an Independent Qualified Person as defined by NI 43-101. The Mineral Resource Estimate in the April 25, 2022 news release has been classified in accordance with CIM Definition Standards on Mineral Resources and Mineral Reserves (May 14, 2014).

1 - Disclaimer - Historical Resource Estimate - North Rock

Readers are cautioned that the Company has not attempted to verify historic mineral resource estimates and therefore readers should not place any reliance on any historical estimate. A qualified person has not done sufficient work to classify a historical estimate as a current mineral resource, additionally, a qualified person has not yet determined what work needs to be done to upgrade or verify a historical estimate as a current mineral resources or mineral reserves.

The Company is not treating any historical estimates as current mineral resources.

A Historical Resource Estimate on the Beaver Pond Zone of the North Rock project is quoted at 1 million tons grading 1.2% copper by Bergman (1973) (Ontario Mineral Deposit Inventory record MDI52C11NE00029). The parameters, methodology and categorise used are not known, and thus the reliability of the estimate cannot be determined, however, it is still considered relevant as underground development and diamond drilling in the 1960 & 1970s supported the estimate and provides a guide for future exploration.

Qualified Person

The technical information in this release has been reviewed and verified by Neil Pettigrew, M.Sc., P. Geo., Vice President of Exploration and a director of the Company and the Qualified Person as defined by National Instrument 43-101.
