Raptor Metals Ltd has completed a borehole electromagnetic survey across twelve diamond drill holes at its 100%-owned Chester Copper Project in the Bathurst Mining Camp of New Brunswick, Canada, identifying multiple conductive responses linked to known copper mineralisation.

The survey traced a prominent shallow west-dipping conductor system across six holes in the central portion of the project. This central system correlates with previous high-grade intercepts, including 3.58 metres at 2.9% copper from 11.55 metres in hole CDH001. A second discrete conductor system was defined across four holes at the eastern end of the surveyed area, supporting continuity between drill intervals.

Interpretation by independent consulting geophysicist Brett Adams identified strong off-hole responses indicating conductive material adjacent to existing drilling, including the survey's strongest response near CDH001. These results correlate closely with previously interpreted airborne versatile time-domain electromagnetic data and magnetic anomalies, providing three independent geophysical datasets supporting the same mineralised trend.

“The strong off- hole responses are particularly important because they give us clear areas to follow up, rather than simply stepping out from existing intersections. Combined with the VTEM, magnetic and drilling data, we now have a much stronger basis for deciding where the next holes can add the most value.” 

— Brett Wallace, Managing Director

The company plans to integrate these datasets with updated drilling results to refine its three-dimensional geological model and intends to extend surveying to additional target areas as drilling advances.

Furthermore, the company commenced a core cutting and multi-element sampling program across twenty historic diamond drill holes at Chester in September 2026. Assay results are anticipated four to six weeks following sample dispatch, while follow-up drill targets are being designed to test both the off-hole conductor responses at CDH001 and the western extension of the conductor system indicated by airborne data.
