GT Resources Samples 5.6 g/t Gold from Schist Target at the CD Gold - Copper Porphyry Project, Yukon

Initial 2026 work at CD refines porphyry and vein targets and sets up a permitted drill campaign after pending geophysical and geological studies.

Rhea-AI Summary

GT Resources (CGTRF) reports initial 2026 field results from its CD gold-copper porphyry project in Yukon, including 5.6 g/t gold sampling.

The program of mapping, prospecting and soil sampling at the Maloney porphyry target confirmed historic gold-copper anomalies and outlined strong phyllic, potassic and skarn-style alteration associated with feldspar porphyry dykes, coincident with magnetic and IP chargeability highs. A focused airborne MobileMT survey was completed to refine 3D targeting, with results pending, and the project holds valid drill permits until 2033.

At the Schist Target, prospecting returned up to 5.64 g/t gold in breccia material, with over 10% of 41 samples above 1.0 g/t gold, and soil samples up to 0.141 ppm gold confirmed historic soil anomalies. GT plans mineralogical and age-dating studies before a 2,500–3,000 m diamond drill program in 2027 to test porphyry and high-grade gold-silver vein targets.

Toronto, Ontario--(Newsfile Corp. - September 9, 2026) - GT Resources Inc. (TSXV: GT) (OTCQB: CGTRF) (FSE: 7N1) the ("Company" or "GT") is pleased to announce initial results from the 2026 field program on the recently optioned CD 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 valid drill permits until 2033 and co-incident soil and geophysical anomalies.

"GT's first work program at CD consisted of geological mapping, prospecting and soil sampling. The field program confirmed historic soil and bedrock gold-copper anomalies and significantly expanded our knowledge of the geology and alteration styles present on the property. This work has re-enforced our thesis that we have an untested porphyry system, and we also have indications of skarn type mineralization.

The work program also included a focused airborne MobileMT survey ("Mobile MagnetoTellurics") results of which are expected shortly. This technology was specifically chosen for its ability to map subsurface resistivity and conductivity to help identify disseminated sulphide mineralization, alteration, and geological contacts at depth. The data being obtained complements the existing ground-based IP ('Induced Polarization") and magnetics surveys thereby allowing GT to create a detailed 3D model of the Maloney Porphyry target which will help identify high-priority drill targets," commented Neil Pettigrew, Vice President of Exploration.

The CD Project exhibits significant geological parallels to Western Copper and Gold's Casino Porphyry deposit, situated 90 kilometers to the northwest. The Casino deposit hosts a Measured and Indicated Resource Estimate of 7.6 billion pounds of copper and 14.8 million ounces of gold (Roth et al. 2022 ).

Exploration Plan and Next Steps

2026

GT's inaugural work program has aided the definition of Maloney Porphyry targets and reduced the reliance on expensive higher risk broadly spaced or conceptual drill testing, thereby supporting a more efficient allocation of exploration risk capital.

Mineralogical studies to further refine porphyry style alteration halos and age dating of prospective porphyry intrusive rocks are planned prior to drill testing.

2027

GT's plans to conduct a 2,500 to 3,000 meter diamond drill program at the beginning of the exploration season. This campaign will be designed systematically to test the gold-rich copper porphyry potential and high-grade gold-silver vein targets.

Field Program Highlights

Maloney Target:

• Multi-Intrusive Porphyry System:

  • Geological mapping revealed a series of feldspar porphyry dykes some of which possess disseminated copper mineralization and porphyry-style stockwork veining. Traditionally these dykes have been assigned to the older Whitehorse suite but remain un-dated and may simply represent a different phase of the prospective younger Casino / Prospector suite pointing toward a multi-intrusive porphyry centre at Maloney.

• Porphyry Style Alteration and Brecciation:

  • Strong phyllic (sericite-quartz-pyrite) alteration is associated with quartz-feldspar porphyry brecciation of wall rock quartzite.

  • Localized potassic actinolite-magnetite-quartz+/-biotite alteration.

  • Widespread epidote-magnetite-pyrite alteration of wall rock especially felsic tuff proximal to feldspar porphyry dykes suggests potential for copper- gold skarn style mineralization.

• Coincident Soil and Geophysical Anomalies with Alteration Halos

  • The central magnetic high is a result of strong magnetite alteration of feldspar porphyry dykes and wall rock.

  • The IP chargeability anomaly correlates well with a strong gold-in-soil anomaly which in turn correlates with a zone of strong brecciation and phyllic alteration surrounding the magnetic high.

Schist Target, an untested vein hosted gold-silver system

• Prospecting returned up to 5.6 g/t gold in weathered breccia vein material confirming historic results (6.29 g/t gold in grabs and trench chip samples of 1.67 g/t gold over 6.5 meters)

• Of the 41 prospecting samples collected over 10% returned greater than 1.0 g/t gold

• Soil sampling returned up to 0.141 ppm gold confirming historic gold-in-soil anomalies

• Recent work suggests the Schist Target is a structurally controlled vein breccia zone with a strong arsenic-antimony-mercury-lead pathfinder signature suggesting an epithermal gold system likely resenting a more distal porphyry-related hydrothermal system.

Geology of the CD Project

The CD Project lies within the Yukon-Tanana terrane (Figure 1), a continental arc that developed along the ancient Pacific margin of North America from the Late Devonian to Permian and is situated between the Tintina Fault to the northeast, and the Denali Fault to the southwest. 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, psammite and conglomerate, including marble horizons metamorphosed to amphibolite grade. The Snowcap Assemblage has been intruded by numerous intermediate to felsic granitoid batholiths since the early Jurassic, notably in the Casino and CD areas by the voluminous mid-Cretaceous Whitehorse Suite. The Whitehorse Suite intrusive event (~100-111 million years) was followed by a more restricted late Cretaceous Casino / Prospector Mountain Suite (~79-72 million years) felsic intrusive event which is closely associated with mineralization at the Casino, Klaza and Mount Nansen deposits. (Figure 1).

Geological mapping and exploration in general at CD has historically been complicated by limited outcrop, surficial cover, loess and deep weathering, typical of parts of the unglaciated or partially glaciated Yukon Plateau. From available outcrop, the geology, structure and intrusive relationships at the CD Project have many analogs to the Casino deposit. At Casino a late Cretaceous porphyry (Patton Porphyry) has intruded and brecciated surrounding Whitehorse rocks. This strongly phyllic and potassic altered-breccias which hosts the gold-rich copper mineralization contains abundant disseminated pyrite and chalcopyrite and forms a discrete (~1,800 x 1,000 m) pipe shaped halo surrounding the relatively massive Patton Porphyry. At CD, mapping indicates similar relationships with both Snowcap rock intruded by late Casino / Prospector suite age (~75 million years) quartz-feldspar porphyritic rocks with widespread phyllic alteration (sericite-quartz-pyrite) and local intense brecciation. Geophysical data at CD displays a similar geometry to Casino with a magnetic core interpreted to represent a series of feldspar porphyry dykes and associated magnetite-rich alteration plunging to the southeast flanked by a phyllic altered and brecciated IP chargeability 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 been conducted. The mineralization at Schist may be related to the nearby, younger Klaza-style vein hosted gold-silver-lead-zinc deposit (Figure 1) or a more distal epithermal phase of yet to be identified porphyry system. The Schist target comprises gold, silver bearing breccia veins with arsenic-antimony-mercury-lead pathfinder signatures in hydrothermally altered Snowcap assemblage rocks. Mineralization within the breccia veins consists of fine-grained disseminated pyrite and arsenopyrite with manganese oxide, limonite and strong silica-sericite alteration. The Schist target contains a widespread (2,000 x 500 m) 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.

FAQ

What additional work is planned before drilling at the CD Project?

Before drilling, GT Resources plans mineralogical studies to better define porphyry-style alteration halos and age dating of prospective porphyry intrusive rocks. These studies are intended to further refine the geological model and support targeting for the planned 2027 diamond drill program.

What is the purpose and status of the MobileMT survey at CD?

The airborne MobileMT (Mobile MagnetoTellurics) survey was conducted to map subsurface resistivity and conductivity to help identify disseminated sulphide mineralization, alteration and geological contacts at depth. The data will complement existing IP and magnetic surveys to create a detailed 3D model of the Maloney porphyry target, and results are expected shortly.

How did GT Resources handle QA/QC for the 2026 sampling?

A total of 70 prospecting and 10 soil samples were submitted, with certified reference materials (standards and blanks) inserted every tenth sample. All standards were within three standard deviations of certified values, and blanks were below the 0.005 g/t gold detection limit. Samples were analyzed by ALS Geochemistry in Whitehorse using fire assay with atomic absorption finish for gold and four-acid digestion with ICP-AES for multi-elements.
