A secondary 9,000m aircore drilling program is now underway to follow up these results and define the extent and geometry of high-grade shoots.  

Ora Banda Mining (ASX:OBM) has achieved further exploration success on the back of new results from first-pass regional air-core (AC) and brownfields reverse circulation (RC) drilling programs conducted in the first half of CY21.

These results have been received for the entire exploration program with intersections for the Victoria Workings, Blue Tongue, Callion Cross, South Pole, German Charlie and Sky prospects.

OBM said while drilling was completed in the first half of 2021, assay results had been held up due to excessive turnaround times at the laboratory.

Highlights from the drilling program include multiple intersections from Victoria Workings with one result – 19 metres at 1.5g/t gold from 12m returned from Sky:

  • 5m at 30.7g/t gold from 127m (Victoria Workings);
  • 5m at 4g/t gold from 54m; (Victoria Workings)
  • 4m at 6.5g/t gold from 27m (Victoria Workings); and
  • 1m at 13.7g/t gold from 74m (Victoria Workings).

Encouraged by strong gold results

OBM managing director, Peter Nicholson, said the company was greatly encouraged by the strong gold results coming from Victoria Workings located just 6km southwest of the active Riverina open pit mine.

“We will be looking forward to continued drilling success in this area,” he said.

“The Sky result is also exciting and comes from an area that has been rated as a highly prospective mineralised corridor extending out of the Sand King open cut mine.

“This area really is wide open and only lightly drill tested, which is surprising given its proximity to a very well mineralised gold system.”

Drilling results

At German Charlie the best intersection returned 20m at 0.42g/t gold, indicating the mineralisation continues along the structure that hosts both the Theil Well and New Mexico deposits.

Aircore drilling at South Pole returned results showing numerous broad, low-grade gold intersections – RC drilling will be planned to test the anomalous zones at depth.

At Callion Cross, seven holes returned surface gold anomalism of possible alluvial nature with the best result comprising 8 metres at 0.84g/t and 4 metres at 1.49g/t.

Further work is required to determine the source of this anomalism.

An RC drilling program of eight holes for 880m was undertaken at the Blue Tongue prospect to test beneath the pit as well as testing the southerly plunging mineralisation.

Hole BTRC008 returned 4m at 3.30g/t gold from 92m and in addition, one hole intersected a reasonable quantity of ground water in a fracture-controlled aquifer.

Ora Banda believes this provides encouragement for a water source to supply the mining operations planned for Iguana.

Next steps

At the Victoria Workings prospect, results were returned along the southern and central section, which the company said are open along strike and will require further investigation.

Meanwhile at Sky, RC drilling is being planned to explore the extent of mineralisation identified in the first pass work.

Additional infill AC drilling is also planned to test for narrow-vein style mineralisation in the stripped profile.
