GT Resources Secures Drill Permitted Yukon Gold-Copper Porphyry Project Near Casino Deposit

Toronto, Ontario--(Newsfile Corp. - May 20, 2026) - GT Resources Inc. (TSXV: GT) (OTCQB: CGTRF) (FSE: 7N1) (the "Company" or "GT") is pleased to announce it has entered into an earn-in-agreement (" Agreement ") to acquire the CD Project in the Yukon's Dawson Gold Range, located near Carmacks (the " Property " or " CD ") (Figure 1). CD hosts a Gold - Copper porphyry target, with valid drill permits until 2033. The CD Project exhibits significant geological parallels to Western Copper and Gold's Casino deposit, situated 90km to the northwest.

The Casino deposit hosts a Measured and Indicated Resource Estimate of 7.6 billion pounds of copper and 4.8 million oz gold. ( Roth et al. 2022. ) "The Yukon is a premier, underexplored Tier 1 jurisdiction. After an extensive search for gold-rich porphyry systems, CD emerged as our top priority. It represents a rare combination of an advanced greenfield project with a clear exploration model, potential to host a muti-billion tonne deposit, de-risked drill targets, and comes with a 50,000 meter drill permit in place.

CD possesses many similarities to the nearby Casino deposit, and we believe that there is great potential for additional large-scale deposits in the Dawson Range Gold Belt which has been significantly under explored for porphyry-style deposits," commented Neil Pettigrew, Vice President of Exploration. Investment Highlights Why we like CD: The project boasts a well-developed Gold - Copper porphyry target A secondary untested vein hosted Gold - Silver system is present (Schist target) Straightforward exploration model with drill ready targets Rapid discovery timeline being fully permitted for up to 50,000m of drilling Emerging gold-rich copper porphyry district Compliments our existing Yukon strategy Politically safe jurisdiction with a well-regulated operating environment Clear Model: CD mimics the geology, age, and alteration of the nearby Casino deposit Data-Driven Advantage: Over 15,000 soil samples, 90 line-km of Induced Polarization ("IP"), and 690 line-km of drone magnetics have refined targets that remain virtually untested (only 800m of historical drilling to date) Similarities to the Gold - Rich Casino Copper Porphyry Deposit: Geology: Similar rock types, ages, alteration and structures (Figure 2) Lithology & Timing: Gold - Copper mineralization is associated with late Cretaceous porphyritic felsic intrusives (Casino / Prospector Mountain suite). These units intrude older Whitehorse Suite granites and Snowcap assemblage gneisses/schists.

Structural Control: The intersection of regional northwest and northeast trending structures, providing dilation for porphyry emplacement. Alteration: Brecciation and veining with widespread potassic and local phyllic+propylitic alteration. Geophysics: Geophysical anomalies coincident with geochemical anomalies (Figure 3).

Magnetic Core: A central magnetic high anomaly associated with porphyritic Intrusive rocks and coincident with Cu-in-soil anomaly. Chargeability Halo: An IP chargeability anomaly flanking the core magnetic anomaly coincident with Au-in-soil anomaly. Geochemical Footprint & Historical Validation: CD hosts a 1,200m x 400m Gold - Copper - Molybdenum Anomaly (Figure 3).

Historical drilling (only 6 holes) demonstrated the presence of a mineralized system but notably failed to test the recently defined primary IP - Gold in-soil target. Drilling (1970s) 0.15% Cu over 15.2 m (hole 76-2) 0.09 g/t Au, 0.10% Cu over 21.3 m (hole 76-4) Trenching (1970s) 0.43 g/t Au, 0.15% Cu, 196 ppm Mo over 5 m Grab Samples (2011-2018) 0.81 g/t Au, below a 632 ppm Au-in-soil sample Soils (2011-2018) Peak soil values of 1,270 ppm Au, 1,485 ppm Cu, and 42 ppm Mo Schist target, an untested vein hosted gold - silver system Undrilled Large Gold - Arsenic in-soil anomaly (2,000m x 500m) 1.67 g/t Au over 6.5 meters in historic (2011) trench chip samples 6.29 g/t Au and 7.6 g/t Ag; 2.78 g/t Au and 25.7 g/t Ag in Historic (2013-2015) grab samples Potential similarities to nearby Au-Ag Klaza and Au-As Coffee deposits Figure 1.

This pattern is interpreted to be a magnetic porphyritic intrusive plunging to the southwest surrounded by an alteration halo, brecciation and veining similar to the mineralized breccia zone which surrounds an unmineralized porphyry intrusive core at the Casino deposit.

In the CD Project vicinity, specifically the Maloney target area, the terrane is dominated by the Devonian and older rocks of the Snowcap Assemblage, which is in turn dominated by fine clastic rocks, quartzite and conglomerate, including marble horizons metamorphosed to amphibolite grade. The Snowcap Assemblage has been introduced by numerous intermediate to felsic granitoid batholiths since the early Jurassic, notably in the Casino and CD area by the voluminous mid-Cretaceous Whitehorse Suite. The Whitehorse Suite intrusive event was followed by a more restricted late Cretaceous Casino / Prospector Mountain Suite (~79-72 million years) felsic intrusive event which is closely associated mineralization at Casino and Klaza deposits is the (Figure 1 & 2).

Geological mapping and exploration in general at CD has historically been complicated by extensive glacial loess and weathering as the bulk of the area is unglaciated. From what little outcrop is available the geology, structure and intrusive relationship of the CD Project have many analogs to the Casino deposit. At Casino a late Cretaceous Porphyry (Patton Porphyry) has intruded and brecciated surrounding Snowcap and Whitehorse rocks.

This high phyllic and potassic altered breccia which hosts the gold-rich copper mineralization contains abundant disseminated pyrite and chalcopyrite and forms a discrete (~1,800 x 1,000m) pipe shaped halo surrounding the relatively massive Patton Porphyry (Figure 2). At CD we see similar relationships with both Snowcap and Whitehorse suite rocks intruded by late Casino / Prospector suite age (75 million years) porphyritic rocks with widespread potassic and phyllic alteration and local brecciation. The Geophysics at CD display a similar geometry to Casino with a magnetic core interpreted to represent a porphyry plug plunging to the southeast flanked by an IP chargeable rim (Figure 3).

Another style of mineralization present at CD is the vein hosted gold-silver mineralization present at the Schist target (Figure 4). Less is known about this style of mineralization, and no drilling has every been conducted, the mineralization may be related to the nearby younger Klaza-style vein hosted gold-silver-lead-zinc deposit or the older Coffee-style disseminated gold-arsenic deposit (Figure 1). The Schist target comprises gold, silver and arsenic bearing veins in hydrothermally altered metamorphic rocks.

Mineralization within the veins consist of fine-grained disseminated pyrite and arsenopyrite with manganese oxide, limonite and sericite alteration. The Schist target contains a widespread (2,000 x 500m) gold and arsenic-in-soil anomaly and numerous placer mining claims have recently been staked in the area. Structurally CD, Casino and Klaza are all located near the intersection of large-scale northwest and smaller scale northeast structures which may provide dilation for late Cretaceous porphyry intrusions and/or hydrothermal vein formation.

Exploration Plan - Next Steps 2026 The 2026 field season is dedicated to high-resolution data acquisition to precisely define the maiden drilling program. Given the heightened exploration activity in the Yukon, GT has optimized the earn-in schedule to prioritize advanced geophysical and geological modeling throughout the current year. A key component of the 2026 work program is a property-wide airborne survey utilizing Expert Geophysics' MobileMT (Mobile MagnetoTellurics) system.

This cutting-edge, natural-field EM (ElectroMagnetic) technology is specifically chosen for its ability to map deep subsurface resistivity and identify subtle disseminated sulphide mineralization that standard VTEM (Versatile Time Domain Electromagnetic) surveys miss. By integrating MobileMT data with existing ground-based IP and magnetics, GT will develop a comprehensive 3D model to pinpoint the highest-conviction drill targets. 2027 Building on the 2026 data, GT plans to conduct a 2,500-3,000 meter diamond drill program. This campaign will systematically test the gold-rich copper porphyry potential and the high-grade gold - silver vein targets at the Schist target.
