OD6 Metals (ASX:OD6) will kick off downhole EM surveying at its Gulf Creek Copper Project in New South Wales this weekend, marking the next key step in refining targets across what the company views as a prospective VMS corridor.
The work follows the completion of four diamond holes and several RC holes drilled earlier in the year.
The DHEM program is designed to detect off-hole conductors — the type of dense, copper-rich sulphide bodies that drilling alone can miss — with processed results expected early in the new year. Surveys will cover recent holes at Big Bend, Northwest, West Limb and beneath the historic Gulf Creek Mine, supplemented by earlier RC holes where copper mineralisation has been logged.
Drilling to date has intersected VMS-style stratigraphy including exhalative cherts, hydrothermal alteration and minor sulphides, confirming the geological model despite slower progress on the ground. With DHEM now underway, OD6 will pause drilling to ensure the next round of work is sharply targeted, with a shift back to faster, cost-effective RC drilling expected in 2026.
Managing Director Brett Hazelden said the survey represents “an important step” in vectoring toward potential high-grade copper positions at depth, noting the phase two holes have already validated several previously untested magnetic anomalies.
OD6 holds approvals for up to 25 holes totalling 7,500m, as Gulf Creek continues to build out its position as the company’s copper exposure alongside its flagship Splinter Rock rare earths project.
