Metal Energy's AMT Survey Accelerates Exploration Targeting at Highland Valley

In This Article:

Highlights:

  • Metal Energy has received results for a 60 km2 ground-based AMT survey covering the eastern part of Highland Valley project.

  • AMT maps intrusive phases of the Guichon Creek Batholith, which hosts Canada's largest copper mine - Teck's Highland Valley Copper operation.

  • Based on the results, Metal Energy has identified seven targets, including high-priority Zone 2 and Zone 1.

Toronto, Ontario--(Newsfile Corp. - February 26, 2025) - Metal Energy Corp. (TSXV: MERG) (OTCQB: MEEEF) (the "Company" or "Metal Energy") is pleased to announce that it has completed and received inversion results for a large 60 km2 ground-based Audio Magnetotellurics (AMT) survey covering the eastern part of its Highland Valley project. This AMT data is an important part of the Company's systematic, multi-parameter exploration targeting strategy at Highland Valley.

What does AMT see?

AMT helps map different intrusive phases of the Late Triassic Guichon Creek Batholith, which hosts Canada's largest copper mine - Teck's Highland Valley Copper operation. These phases have distinct physical properties that can be identified using AMT, magnetics, and gravity:

  1. Younger/Inner Phases (Bethsaida, Skeena, Bethlehem) - More resistive, less magnetic, and less dense. These are the primary source of mineralization in the district.

  1. Older/Outer Phases (Highland Valley, Border) - Less resistive, more magnetic, and denser. These often contain mineralization.

Interpretation of Results

Our data suggests a northeast-dipping contact between the inner and outer batholith, with irregularities extending upward (Figure 1). Mineralization is found within (Zone 1) and along the boundaries (Zone 2) of similar AMT resistors, making them high-priority exploration targets. These features may represent intrusive dike swarms, stocks, or cupolas-structures known to concentrate mineralization in porphyry Cu systems.

While the AMT survey does not directly detect mineralized zones due to its broad 500 m spacing, porphyry Cu mineralization and alteration can influence the resistivity patterns identified. Additionally, geophysical data may highlight younger post-mineral faults that displaced the Guichon internal contacts, which are best seen in the Company's high-resolution airborne magnetic data (Figure 2).
