The priority nickel-copper-cobalt targets have been identified from detailed examination of past soil geochemistry, airborne and ground electromagnetic surveys by previous explorers.

DMC (ASX:DMM) says the target areas are consistent with potential for buried nickel-copper-cobalt mineralisation and will be ground-truthed with detailed soil geochemistry and ground geophysical surveys.

Results from the geochemical and ground geochemical surveys will then be followed up by diamond drilling to test the anomalies for potential nickel sulphide mineralisation at the Trinity Project, within the wider Fraser Range Project (FRP) in Western Australia.

The company is working to engage geophysical and geochemical survey contractors to begin exploration on the ground at Trinity.

Technical summary

DMC has compiled an extensive digital database of previous exploration data covering the FRP.

The company has obtained all previous company geochemical data on the FRP held in the Western Australian Mineral Exploration (WAMEX) database of the Western Australian Department of Mines, Industry Regulation and Safety (DMIRS).

Soil geochemical coverage is generally on a regional 800m x 400m survey grid across the tenements with limited more detailed 400m x 400m grid infill in some areas.

Examination of the data has identified some surveys where the regional grid was suboptimal in sampling media chosen and may not be suitable for nickel sulphide exploration.

Target areas have been prioritised based on whether they have consistent multiple soil geochemical trace element and trace element ratio (nickel, nickel/chromium and/or Kambalda Ratio (nickel/chromium x copper/zinc) and geophysical (magnetic and electromagnetic) characteristics consistent with the potential signature of buried magmatic nickel sulphide systems.

Next on the agenda

Planning is underway to start field work on the ground to test the priority targets identified.

A program of geochemical sampling and ground EM geophysics will be designed to test the anomalies and advance the targets to drill testing.

The company is in the process of engaging contractors to carry out the work programs as detailed below as soon as feasible.
