Still an ore-some lode

The Rasp Mine was proof there was a lot of mining still to do in Broken Hill, Professor Ian Plimer said yesterday.

Professor Plimer is a Director of CBH Resources and a geologist of wide repute. 

He is intimately familiar with the city's geology and has worked with the Broken Hill orebody for the past 42 years.

CBH's Rasp Mine was granted final development approval by the NSW Government yesterday, and Prof Plimer said he was "very, very happy" to hear it.

"We acquired the CML 7 (mine lease) as CBH in 2001; it's been a decade of working up resources for final approval," he said.

"I think the Rasp mine tells us what everyone already knows - that the orebody has a lot of juice left in it.

"I think it will still be operating when I am dead. We're certainly very happy to be keeping Broken Hill going as a mining town."

Prof Plimer said Rasp's projected lifespan of 15 years was very conservative.

""We have drilled a 1.2 kilometre line of mineralisation that we know is 3.8 kilometres long," he said.

"We're using that as our basis, but we know there is mineralisation there that hasn't been drilled with intensity."

CBH will mine beneath the Miner's Memorial but not the city - their lease ends at Crystal Street.

Professor Plimer said a line of mineralisation headed to the west into Perilya's property that had not yet been mined, as it was very deep.
