Star Metro - Tocvan Drone Magnetic Data Strengthens Gold-Silver Targets Across Gran Pilar; Identifies Broad Zones for Expansion Potential

Key Benefits

The drone magnetic data offers several advantages for exploration:

• High-resolution coverage over the entire project, enabling efficient identification of potential subsurface features potentially hosting mineralization.

• Integration potential with existing surface geochemistry, geological mapping, and drill data to support targeted exploration and reduce overall risk.

"We are excited about the completion of this extensive drone magnetic survey at Gran Pilar," said Brodie Sutherland, CEO of Tocvan. "The high-quality data sets a strong foundation for our next phases of analysis and interpretation, which will guide our resource expansion efforts in this promising district. We can see a continuation of many of the structural features we are testing today with drilling; these structures have the potential of expanding our targets across the area with a specific emphasis on the underexplored Central portion of the project. In addition, we are seeing a large regional low with inset structural corridors in the North that coincides with our broad alteration zone, another positive sign for expanding on targets."

Next Steps

• The Company plans to proceed with detailed data analysis and interpretation, including correlation with geological and geochemical datasets. This will be followed by magnetic inversion modeling to estimate the depth, shape, and susceptibility of magnetic sources, further refining exploration targets for the ongoing 20,000-meter drill program and permitted pilot mine development.

Summary of the Data

The processed magnetic data includes Total Magnetic Intensity (TMI), TMI Reduced to the Pole (TMI-RTP), Calculated First Vertical Derivative (1VD) of the TMI-RTP, and Tilt Derivative of the TMI-RTP.

The survey provides comprehensive geophysical datasets that map magnetic field variations across the project area. Key components include:

• Total Magnetic Intensity (TMI): Raw measurements of the Earth's magnetic field strength.

• TMI Reduced to the Pole (TMI-RTP): Adjusted data to simulate measurements at the magnetic north pole, improving anomaly interpretation.

• First Vertical Derivative (1VD) of TMI-RTP: Enhances detection of near-surface features and structural boundaries.

• Tilt Derivative of TMI-RTP: Aids in identifying the depth and geometry of magnetic sources.

Quality Assurance / Quality Control

Rock and Drill samples were shipped for sample preparation to ALS Limited in Hermosillo, Sonora, Mexico and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold was analyzed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Over limits for gold (>10 g/t), were analyzed using fire assay with a gravimetric finish. Silver and other elements were analyzed using a four-acid digestion with an ICP finish. Over limit analyses for silver (>100 g/t) were re-assayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's robust quality assurance / quality control protocol.
