GT Resources Reports MT Anomaly Coincident with Gold-In-Soils and IP Chargeability at CD Gold - Copper Porphyry Project, Yukon

Toronto, Ontario--(Newsfile Corp. - September 17, 2026) - GT Resources Inc. (TSXV: GT) (OTCQB: CGTRF) (FSE: 7N1) (the "Company" or "GT") is pleased to announce results of the first MobileMT ("Mobile MagnetoTellurics") survey on the CD Copper-Gold Project in Yukon's Dawson Range Gold Belt, located near Carmacks (the " Property " or " CD ") (Figure 1). CD hosts a gold-copper porphyry target with co-incident soil and geophysical anomalies, and valid drill permits until 2033. "The MobileMT survey identified a 'blind', concentric body, which may represent a buried porphyry intrusion located directly south of a coincident strong gold-in-soil and Induced Polarization ("IP") chargeability anomaly (Figure 1, 2 & 3). This combined with new geological mapping leads us to believe that a multi-intrusive centre is present at the Maloney Porphyry Target, similar to Forge Resources Corp's Alotta project (Figure 4). Additionally, the MobileMT survey identified an area of low resistivity coincident with the IP chargeability anomaly, thereby providing additional conviction in our target by de-risking with multiple exploration tools. MobileMT was specifically chosen for its ability to help map disseminated sulphides, alteration, and geological contacts. While IP is excellent at identifying near surface features, MobileMT is geared toward greater depths, and combining the two has allowed GT to create a detailed 3D model of the Maloney porphyry target and refine drill targets. In simple terms, these results mean we have isolated a high-priority, drill-ready target that shares many similarities with major regional deposits. This allows us to target our upcoming drilling with higher precision and lower geological risk," commented Neil Pettigrew, Vice President of Exploration. The CD Project exhibits compelling geological parallels to Western Copper and Gold's Casino porphyry deposit, situated 90 kilometers to the northwest (Figure 1). The Casino deposit hosts a Measured and Indicated Resource Estimate of 2.39 billion tonnes containing 7.6 billion pounds of copper and 14.8 Moz of gold ( Roth et al. 2022 ). Geophysical Program Highlights Maloney Target: Potential Buried Porphyry System: MobileMT has identified an undrilled, large (~1 x 1 kilometer) highly resistive body, interpreted as a porphyry intrusive center intruding Snowcap gneiss. Multi-Intrusive Porphyry System: Geological mapping and geophysics are now pointing toward a multi-intrusive porphyry centre at Maloney. Correlation between MobileMT an IP anomalies The MobileMT survey identified a zone of low resistivity (i.e. conductivity) on the northern flank of the resistive body, which coincides with the IP chargeability anomaly, a strong gold-in-soil anomaly, and overlapping zones of strong brecciation and phyllic alteration on surface, building confidence in the MobileMT system. These targets remain untested by drilling. Figure 1. 3D isometric view (looking northwest) of CD's Maloney porphyry target (the Maloney target) showing a MobileMT cross section and a resistivity depth slice at 600 m below surface. The depth slice highlights a discrete body ("resistive core") interpreted as a buried, potassic-altered porphyry intrusion, located directly south of the coincident gold-in-soil and IP chargeability anomaly. Isoshells show a magnetic-high core (purple) flanked by an IP chargeability high rim (grey). This pattern is interpreted to be a magnetite-bearing porphyry dykes and associated alteration (epidote-pyrite-magnetic & actinote-magnetite-quartz+/-biotite) plunging to the southeast. surrounded by strong phyllic (sericite-quartz-pyrite) alteration halo, and brecciation and veining similar to the breccia-hosted mineralization which surrounds a porphyry intrusion (the Patton porphyry) at the Casino deposit. These dykes and associated alteration may represent the upper levels of the porphyry system with the larger intrusive located at depth to the south, as illustrated in Figure 2. The Mob...
