American Pacific Mining Nears Completion of Underground LiDAR Survey to Advance Madison Project Development
Rhea-AI Summary
American Pacific Mining (OTCQX: USGDF) has begun a high-resolution underground control and LiDAR survey at the Madison Copper-Gold Project near Silver Star, Montana. WET and Dengel Surveying will traverse the decline to ~800 feet and use an Emesent HVM100 to produce geolocated point clouds and a 3D mesh.
Field work is expected to finish in April 2026 with final deliverables approximately three weeks after completion. The dataset will support 3D geological modeling, refined drill targeting, and underground-access planning.

Vancouver, British Columbia--(Newsfile Corp. - April 28, 2026) - American Pacific Mining Corp. (CSE: USGD) (OTCQX: USGDF) (FSE: 1QC) ("American Pacific", or the "Company") is pleased to announce the initiation of a detailed underground survey program at its Madison Copper-Gold Project ("Madison" or the "Project") located near Silver Star, Montana.
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 ongoing geological modeling, 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 3D scanning of the underground ramp using the Emesent HVM100 system, designed for GPS-denied environments
- Placement of reflective targets to accurately geo-reference the dataset
- Generation of:
- Geolocated point cloud
- 3D mesh model
Field work 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 3D framework of existing underground workings
- Enhancing the Company's ability to integrate historical data with modern datasets
- Supporting refined targeting of deeper skarn and porphyry mineralization
- De-risking future drill collar positioning and underground access planning
The resulting dataset 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 3D 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 dataset ever amassed at Madison uniting the various historical survey methods into one accurate and verifiable package," commented Managing Director of Exploration, Eric Saderholm. "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 modeling, drilling and future mineral inventory calculations cannot be understated."
