- Great Northern Minerals (GNM) completes a reverse circulation (RC) drilling program at its Douglas Creek discovery in Queensland
- The company drilled 20 holes to test mineralisation across three zones in the area and intersected widespread disseminated sulphide mineralisation
- Great Northern Minerals is now planning a follow-up survey to target potential extensions to the mineralisation as well as to target historical magnetic anomalies

Great Northern Minerals (GNM) has completed a reverse circulation (RC) drilling program at its Douglas Creek discovery in Queensland.
The company on Thursday afternoon announced the completion of the program, which included 20 holes for 1080 metres to test three zones of mineralisation.
Drilling successfully intersected a low-angle mineralised structure with widespread disseminated sulphide mineralisation, with up to five per cent visible pyrite and one per cent chalcopyrite.
Early results include seven metres at 20.7 grams per tonne (g/t) silver, 0.1 per cent copper and 0.3 per cent lead from 12 metres downhole and two metres at 0.8 g/t gold, 41.2 g/t silver, 0.1 per cent copper and 0.1 per cent lead from six metres downhole.
Managing Director and CEO Cameron McLean said he was pleased with the results, as they confirmed the presence of disseminated precious metal-rich polymetallic mineralisation.
“The geological information we have gained from the drilling combined with the reprocessed geophysical survey data will guide us in the next phase of exploration as we seek to target porphyry-style mineralisation and targets,” he said.
Great Northern Minerals has begun planning a follow-up induced polarisation survey to target reprocessed historical magnetic anomalies. This work will also target potential depth extensions of the mineralisation intercepted in the recent drilling program.
Company shares were trading at 0.6 cents at 10:51 am AEDT.
