Diatreme Resources has released promising metallurgical results from its Cape Bedford silica/heavy minerals project about 200km north of Cairns.
Initial testwork showed the project was capable of producing high-quality glass-grade silica sand, the company said.
Six bulk samples were wet tabled, resulting in about 80 per cent recovery of a primary silica sand product ranging from 99.6 to 99.9 per cent silicon dioxide and containing less than 0.02 per cent iron oxide.
“Cape Bedford’s potential as a supplier of high-quality silica sand has been reaffirmed by these latest results, with the prospects of generating valuable new jobs for the region and becoming a profitable near-term mining operation as an important part of our mineral sands portfolio,” Diatreme chief executive officer Neil McIntyre said.
He said the company was determined to test the site’s potential as quickly as possible through additional drilling.
High-grade silica is used in glass manufacturing, foundry casting, electronics, ceramics and construction.
The 542sq km Cape Bedford exploration project is located on the same sand dune field as Mitsubishi’s Cape Flattery Silica Mines operation – the world’s largest silica sand mining operation.
