Ora Banda Mining Ltd infill drilling at Riverina South returns up to 3 metres at
The objective of this resource infill drilling program is to close the current drill spacing from a nominal 40 x 25 metres pattern to a 20 x 25 metres pattern to allow the inferred resource to be upgraded.
’s () (FRA:M6N) infill drilling program at Riverina South deposit within the wider Davyhurst Gold Project in Western Australia has delivered strong assay results of up to 3 metres at 32.4 g/t from 34 metres.
Drilling recommenced in mid-January following the release of the Riverina South maiden mineral resource estimate in October 2020 which sits at 650,000 tonnes at 2.1 g/t for 43,000 ounces and includes both an open pit component and an underground component.
This program is the third phase of drilling that has occurred in rapid succession on the Riverina South deposit, which also includes the historical British Lion mine.
“On-track to deliver extensions”
Managing director David Quinlivan said: “This project is on track to deliver mine extensions with the deeper drilling ongoing.
“We are keen to see how the upgraded mineral resource at Riverina South can contribute to the ore stream flowing from main Riverina open pit mining operations.
“The mining is picking up pace, so the time is now in relation to incorporating Riverina South into this larger operation.”
Other notable results include 5 metres at 10.4 g/t from 21 metres, including 2 metres at 24.8 g/t and 13 metres at 3.2 g/t from 25 metres.
The Riverina South drilling program has targeted a 1-kilometre-long, highly prospective strike extension corridor immediately south of the main Riverina mining area where open pit mining commenced in October with ore stockpiles building ahead of the ongoing commissioning of the 1.2 million tonnes per annum process plant.
Further RC drilling
Around 7,400 metres of reverse circulation drilling remains in the phase-3 program, with the current program following on from the phase-1 exploration RC program (32 drill holes for 3,639 metres) completed in early 2020.
The phase-2 RC program totalled 68 holes for 7,338 metres which closed the drill hole spacing down to 40 x 25-metre spacing in two discreet areas at Riverina South and resulted in the declaration of the maiden mineral resource.
Riverina South mineralisation is the direct continuation of the gold mineralisation that is currently being mined within the main Riverina deposit.
