Global Mining Review,
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 programme is designed to provide critical spatial data to support ongoing geological modelling, targeting, and future drill planning.
Survey programme 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.
