AMERICAN PACIFIC MINING NEARS COMPLETION OF UNDERGROUND LIDAR SURVEY TO ADVANCE MADISON PROJECT DEVELOPMENT

American Pacific Mining Corp. has initiated a detailed underground survey program at its Madison copper-gold project, located near Silver Star, Mont.

The company has engaged Water & Environmental Technologies Inc. (WET), in collaboration with Dengel Surveying, to complete a high-resolution control survey and lidar scan of the historical Madison mine underground ramp. The program is designed to provide critical spatial data to support continuing geological modelling, targeting and future drill planning.

Survey program overview

The scope of work includes two primary components:

• Control survey:
  • Establishing precise underground and surface control points;
  • Integrating surface control with underground survey control to ensure spatial accuracy;
  • Traversing the decline to approximately 800 feet from the mine entrance, near the current water level;
• Lidar ramp scan:
  • High-resolution 3-D scanning of the underground ramp using the Emesent HVM100 system, designed for GPS-denied (Global Positioning System) environments;
  • Placement of reflective targets to accurately georeference the data set;
  • Generation of:
    • Geolocated point cloud;
    • 3-D mesh mode.

Fieldwork is expected to be completed in April, 2026, with final deliverables anticipated within approximately three weeks following completion of field activities.

Strategic rationale

This survey represents a key step in advancing the Madison project by:

• Establishing a high-precision 3-D framework of existing underground workings;
• Enhancing the company's ability to integrate historical data with modern data sets;
• Supporting refined targeting of deeper skarn and porphyry mineralization;
• Derisking future drill collar positioning and underground access planning.

The resulting data set will form a foundational component of the company's evolving district-scale geological model, enabling improved interpretation of structural controls and fluid pathways associated with mineralization.

Next steps

The company will integrate the survey outputs into its 3-D geological model and utilize the data to:

• Refine drill targeting beneath historical workings;
• Evaluate potential underground access strategies.

"This underground lidar survey is critically important as it's the first dependable underground data set ever amassed at Madison uniting the various historical survey methods into one accurate and verifiable package," commented Eric Saderholm, managing director of exploration. "With improved underground access caused by receding water, our team has seized the opportunity to rectify and eliminate any previous errors and variances in the available data, both surface and underground. The importance of this procedure for modelling, drilling and future mineral inventory calculations cannot be understated."
