GT Resources Samples 8.2% Copper & New Conductors at North Rock Copper-Nickel-PGE Project

• GT Resources reported an impressive 8.2% copper assay result from a surface grab sample taken from the waste rock stockpile of the historic Beaver Pond Zone at its North Rock project in Ontario, Canada.
• The company completed a bore hole electromagnetic (BHEM) survey, the first geophysical survey of its kind at North Rock, in Q4 2024. The survey successfully identified multiple new conductors both within and outside of the surveyed drill holes, providing GT Resources with high-priority targets for potential massive sulfide mineralization.
• The North Rock project is favorably located in the mining-friendly jurisdiction of Northwest Ontario, Canada. The project benefits from excellent infrastructure including a paved highway, railroad, and power lines that cross the property, which will facilitate cost-effective exploration and potential future development.
• GT Resources is executing on a strategy to build a portfolio of quality copper and nickel exploration projects in low-risk, mining-supportive jurisdictions.
• In addition to the flagship North Rock project in Ontario, Canada, the company is also advancing copper and nickel projects in Finland that have attracted investment from a major mining company.

GT Resources Inc. (TSXV:GT) is a mineral exploration company pursuing a strategy to develop copper and nickel mining projects in mining-friendly jurisdictions in Europe and North America. The company's project portfolio includes the North Rock copper-nickel-PGE project in Ontario, Canada as well as projects in Finland. GT Resources' projects are district-scale opportunities that have attracted strategic investment from a major mining company.

GT Resources announced encouraging exploration results from its North Rock copper-nickel-PGE project in Northwest Ontario, Canada. The company reported an 8.2% copper assay from a grab sample at the historic Beaver Pond Zone and the identification of several new conductors from the first bore hole electromagnetic (BHEM) geophysical survey conducted on the property.

North Rock Project Overview

The 100%-owned North Rock project covers over 7,000 hectares in Northwest Ontario along a 13-kilometer trend of the prospective basal contact of the Grassy Portage Gabbroic Complex. The project benefits from excellent infrastructure, including a paved highway, railroad, and power lines that cross the property.

The copper-nickel-PGE mineralization at North Rock occurs as disseminated to locally net-textured magmatic sulfide near the base of the gabbro complex as well as high-grade massive sulfide footwall veins in the underlying volcanic rocks. Historic work, including approximately 12,000 meters of drilling, identified two shallow zones of mineralization - the Beaver Pond and East Zones.

Historic Resource & High-Grade Sample Results

The Beaver Pond Zone hosts a historic resource estimate of 1 million tons grading 1.2% copper outlined by Noranda in 1958. The zone was discovered in the late 1950s and explored from underground in the 1960s via a 90-meter shaft and drift.

"The North Rock project was one of most significant assets acquired via the 2023 Metalcorp acquisition," stated GT Resources President and CEO Derrick Weyrauch. "High grade copper in grab samples from our first exploration program bear out the significant copper opportunity that North Rock represents."

Reconnaissance grab sampling in Q4 2024 of waste rock from the historic Beaver Pond underground program returned assays up to 8.2% copper, confirming the high-grade nature of the mineralization. Samples were collected from the 10,000 ton surface stockpile and are considered roughly representative of the high, medium and low grade material in the pile. Notably, the mineralization is copper-rich with minor nickel, cobalt, PGEs and gold.

New BHEM Conductors Identified

GT Resources completed the first ever BHEM geophysical survey at North Rock in Q4 2024, which successfully identified several in and off-hole conductors. These are potential drill targets for additional high-grade massive sulfide mineralization.

The survey focused on hole NR07-062, the deepest hole on the property to date. This hole intersected high-grade footwall style mineralization but did not exit the volcanic rocks to test the gabbro-hosted disseminated sulfides. BHEM conductors in the vicinity of this hole could represent further massive sulfide as well as untested disseminated mineralization.

"The BHEM survey results confirm our thesis that the Grassy Portage Gabbro Complex, which hosts the North Rock project, is a favourable setting for not only disseminated copper-rich Cu-Ni-PGE sulphide mineralization but also significant higher grade footwall vein style mineralization," said VP Exploration Neil Petttigrew. "The geological setting draws comparisons to the historic Temagami and Thierry Mines located Ontario, and the Mesaba, NorthMet, and Maturi Deposits hosted with in the Duluth Complex in Minnesota."

Next Steps & Exploration Upside

GT Resources plans to open up historic drill trails to provide access for a larger BHEM survey and to follow up on the newly identified conductors. The company believes the application of modern geophysics and exploration approaches will be key to making new discoveries on this underexplored property.

With a 13-kilometer prospective horizon, a historic high-grade resource, and multiple untested exploration targets, North Rock provides GT Resources and its shareholders with significant discovery and growth potential. The recent exploration results support the company's view that the project represents a substantial copper opportunity with upside from nickel, PGEs, and other metals.

For Investors

The initial high-grade sampling and geophysical results from the North Rock project are highly encouraging for GT Resources' copper-focused exploration strategy. The company has confirmed the potential for additional high-grade copper mineralization on the project and identified new massive sulfide targets. With a sizeable land package in a productive mining jurisdiction, a historic resource to build upon, and numerous untested drill targets, GT Resources offers investors exposure to both resource expansion and grassroots discovery. We expect the application of modern, systematic exploration including geophysical surveys and drilling to yield further positive results from this promising copper-nickel-PGE project.
