The Stage 2 drilling comprised 5,600 metres of aircore and reverse circulation drilling. The drilling into each of Zones A and B included about 500 metres of diamond core into fresh rock.
Cora Gold said the drilling encountered broad zones of moderate to intense quartz veining, consistent with drilling on other parts of the mineralised structure. Visible gold was, once again, observed in many panned samples at the drill rig, the company added.
Test assay work has concluded larger sample sizes are needed to mitigate risk of sample bias and maximise the potential for more representative results, Cora Gold said.
""Panning of samples at the rig often encountered visible gold, ranging from a few grains to over a hundred grains in the pan, with various levels of coarseness. This is not unusual in Birimian gold deposits and as a result test assays have been completed using a variety of techniques to ensure any potential sample bias in the results is managed effectively. Test results have, in general, confirmed the preference to use an assay procedure with larger sample sizes in order to provide better correlation of gold grade with observations of visible gold," Chief Executive Jonathan Forster said.
