Great Boulder Resources Ltd (ASX:GBR) is off to a great start to the year intersecting high-grade gold in its first reverse circulation (RC) drilling for 2023 at Ironbark prospect within the Side Well Gold Project near Meekatharra in Western Australia.
The company’s first drill hole extended the strike of Ironbark north by 50 metres, delivering 31 metres at 2.22 g/t gold from 25 metres, including 6 metres at 8.10 g/t from 26 metres in drill hole 23IBRC001.
The drilling program was designed to extend the Ironbark mineral resource downdip and along strike to the north, as well as infilling previous drilling on some sections.
Other standout assays include:
- 20 metres at 9.41 g/t gold from 111 metres, including, 5 metres at 17.47 g/t from 125 metres;
- 8 metres at 9.89 g/t from 115 metres, including 1-metre at 72.60 g/t from 117 metres; and
- 14 metres at 3.61 g/t from 82 metres, including 9 metres at 5.49 g/t from 82 metres.
“Excellent potential”
GBR managing director Andrew Paterson said: “This is a great start to the year, with our first RC hole at Ironbark extending the strike north by 50 metres and a number of thick, high-grade intersections adding ounces at depth.”
“The northernmost intersection has defined a wide zone of mineralisation; 31 metres down-hole including a higher-grade portion of 6 metres averaging 8.10 g/t gold.
“This result is a significant increase to the mineralised envelope which adds to our expectation that Ironbark has excellent potential for open pit mining.
“The other intersections in this round of drilling add high-grade ounces at depth.
“This small program of RC drilling has added a lot of value. With these results and the recent stellar assays from Mulga start to 2023, I’m looking forward to more assays flowing through in the next few weeks.”
Forward plan
At Mulga Bill, GBR’s RC drill program is continuing, with the current campaign expected to be completed shortly.
Assuming a four-week assay turnaround, results from this drilling are expected to arrive in batches over the coming month.
Furthermore, an aircore program is underway at the project, testing a range of areas within the Mulga Bill corridor, including Flagpole and Loaded Dog prospects as well as interpreted structural targets northeast of Mulga Bill.
