Surefire Resources NL (ASX:SRN) has struck more broad gold in drilling of the emerging gold system at the Yidby Project in Western Australia, with an intersection of 20 metres at 1.73 g/t gold from 80 metres in drill hole YBRC102.
The result builds on previous intersections including 32 metres at 0.25 g/t, 20 metres at 1.35 g/t, 12 metres at 0.28 g/t and 15 metres at 0.44 g/t gold from the same drilling zone.
Results confirm continuity
The latest gold results are from a 13-hole reverse circulation (RC) drilling program centred on the anomalous gold zone at Yidby, an 80-metre wide by 3-kilometre-long area of interest.
This program was designed to test extensions to the current mineralisation while also investigating new priority targets highlighted in reviews of gravity and induced polarisation geophysical data, structural mapping and relogging of drill chips.
SRN has sampled the drill holes on a 4-metre composite basis with intentions to sample 1-metre intervals over any horizon showing gold anomalism.
The project is a ‘blind deposit’ discovered by Surefire beneath transported cover of up to 20 metres thick.
Metallurgical work carried out on samples from Yidby revealed an under-reporting of gold grades in drill results due to the coarse nature of the gold, but excellent gold recovery rates.
The company is confident in Yidby’s prospectivity because of its multi-million-ounce neighbours, including:
- The 3.24-million-ounce Mount Gibson Gold Project 30 kilometres to the south;
- The 1.1-million-ounce Minjar Gold Project 65 kilometres to the northwest; and
- The 1-million-ounce Kirkalocka Gold Project 70 kilometres to the northeast.
Surefire intends to develop Yidby as a shallow, open-cut heap leach operation.
