RT MINERALS CORP. COMPLETES MAJOR UAV MAGNETICS SURVEY AT CASE PROPERTY, ONTARIO - HIGH-RESOLUTION DATA TO GUIDE TARGET GENERATION

RT Minerals Corp. has successfully completed a high-resolution UAV (unmanned aerial vehicle) magnetics survey across its 100-per-cent-owned Case property in Northeastern Ontario. The survey marks a significant milestone in the company's 2025 exploration program and positions RT Minerals for a focused and data-driven advancement of its exploration strategy.

Conducted by Axiom Exploration Group Ltd., the survey covered 687.5 line kilometres (km) and was designed to optimize structural interpretation and magnetic contrast across key geological units. The work was completed with a primary line spacing of 50 metres (m), complemented by select areas flown with 25 m infill spacing to enhance spatial resolution in geologically complex zones.

Survey results and strategic implications

The magnetics survey was flown at low altitudes to maximize resolution, and the data collected met or exceeded industry standards for UAV-acquired magnetometry. Sensor and base station performance were consistent throughout the survey, and data quality was high across the project.

The high-resolution data set will be integrated into the company's existing geological and geochemical models. This integration will allow RT Minerals to refine its exploration focus, enhance structural interpretations and identify potential drill targets across the Case property.

"We're extremely encouraged by the quality and scale of this survey," said Alson Niu, chief executive officer of RT Minerals. "It provides a strong technical foundation for the next phase of work and sets the stage for advancing high-priority targets with confidence."
