Dyno Nobel has completed its first wireless detonator blast using its CyberDet I technology at Westgold Resources’ Big Bell gold mine in Western Australia.

The underground mine saw 34 CyberDet I detonators fired wirelessly, which has produced strong results.

The blast was successful in creating a well-fragmented muckpile at Big Bell, Dyno Nobel stated.

Dyno Nobel Asia Pacific president Greg Hayne said the blast marked a significant milestone for the company.

“We are so pleased to be able to partner with Westgold on the first underground wireless blast ever in Western Australia,” he said.

“The blast was a great success and it’s been really pleasing to hear Westgold’s feedback that it believes CyberDet I will deliver improved safety and efficiency.”

The Department of Mines, Industry Regulation and Safety (DMIRS) approval for the blast was required before it was undertaken at Big Bell.

Westgold’s Big Bell mine is part of its Cue gold assets, with the site expected to become the largest single mine in the Murchison region.

In the long term, it is expected to produce over 300,000 ounces of gold per annum.

Westgold currently owns three gold projects in Western Australia, including the Meekatharra Gold Operations, Fortnum Gold project and the Cue Gold Operations.

The CyberDet I technology allows miners to work in safer environments during blast loading, while also enabling a shorter blast cycle to increase the amount of material mined.

“CyberDet I is Dyno Nobel’s through-the-earth wireless detonator offering, developed on the back of customers telling us it’s technology they need,” Hayne said.

Dyno Nobel is a subsidiary of Incitec Pivot with further trials for the technology expected in Australia

Incitec Pivot Limited chief technology officer Robert Rounsley said one of the key advantages of its wireless offering is its portable design.

“The flexible nature of our communications antenna provides significant operational advantages for our users,” he said.

“We’re looking forward to showing more of our customers the benefits of CyberDet I. It is just one of our premium technology offerings focused on meeting the needs of our customers.

“We are proud of our customer partnerships which are creating innovative, practical improvements in safety, productivity and environmental performance.”
