Ora Banda Mining Ltd (ASX:OBM) has received further high-grade gold assay results from the recently concluded diamond drilling program at Riverina Underground in Western Australia’s Goldfields region.
The 18-holes 3,460 metre diamond drilling program targeted infill and extensions to the current underground resource at Riverina which totals 1,008,000 tonnes at 5.6 g/t for 183,000 ounces.
Highlight results returned from Riverina Underground to date include:
- 5 metres at 16.7 g/t gold from 200 metres;
- 2.8 metres at 21.2 g/t from 253.7 metres;
- 6.8 metres at 8.6 g/t from 143.8 metres; and
- 1.3 metres at 25.3 g/t from 217.8 metres.
The new drilling results will be included in an updated mineral resource estimate (MRE) for Riverina Underground which is currently in progress.
The MRE will be used for mining studies with the aim of publishing a maiden Riverina Underground Ore Reserve shortly thereafter.
“Potential to deliver improved grade and confidence”
Ora Banda managing director Peter Nicholson, said: “These strong results have the potential to deliver improved grade and confidence of the existing underground resource.
“The updated resource will provide a base case for mining studies which will look to demonstrate the underground mining potential at Riverina.
“Additional drilling is planned for later in the year to further increase the extent and confidence in the mineral resource.”
North Shoot remains a high priority exploration target
The Riverina Underground drilling program comprised diamond drilling from surface targeting the Main lodes which were mined from underground between the 1900s and 1930s and again in 1980s.
Main lodes are two sub-parallel, sub-vertical mineralised shears with significant strike length (>1,000 metres) and depth (>250 metres) extent.
The drill program has successfully targeted some upgrades to the resource classification and the down plunge mineralisation extensions to the south.
The North Shoot is yet to be drill tested by Ora Banda but remains a high priority exploration target.
