Develop Global Limited has intersected high-grade mineralisation grading up to 15.7% CuEq from underground drilling at the Woodlawn copper-zinc project in New South Wales, supporting its strategy to expand mine life by 50% to 15 years under Project DM15.

The latest assays from the J Lens returned 12.2 metres grading 15.7% CuEq, including 11.8% copper, 2.2% lead, 10.0% zinc, and 33 grams per tonne silver from 410 metres downhole. Drilling across the D and I lenses also delivered substantial polymetallic widths, including 14.8 metres at 8.4% CuEq at the D Lens.

An intersection within the N Lens confirmed a significant extension situated approximately 190 metres down-plunge from the currently defined resource boundary in an area with no prior drilling. The hole intersected 10.6 metres at 3.3% CuEq, including 4.7 metres at 6.0% CuEq from 390 metres.

“These exceptional results reveal additional high-grade mineralisation within the existing Resource and also extend the known mineralisation outside the Resource.”

“The extensions to the N lens are particularly outstanding and look like the beginning of a significant extension to the known mineralisation.”

— Bill Beament, Managing Director

To accelerate the DM15 initiative, Develop has deployed an additional underground diamond drill rig to the site, bringing the total operating underground rigs to three. The company expects to release assay results for multiple follow-up holes completed at the N Lens as soon as they are received from the laboratory.

Commercial production at Woodlawn was established in April 2026 after the processing plant achieved a steady-state rate of 850,000 tonnes per annum. Financial backing for operations and growth initiatives was bolstered in June 2026 when Develop secured a US$400 million debt facility and warrant package with Trafigura.

Exploration activities have also expanded beyond the main mine site, with a maiden exploration drilling campaign completed at the Currawang Prospect located approximately 10 kilometres from Woodlawn. Assay results and a downhole electromagnetic program are scheduled for the prospect, alongside ongoing evaluation of historic targets across the wider tenure.
