A new storage shed at the E C Andrews Drillcore Facility will house what is known as ‘historical cores.’

“It will hold approximately 100,000 metres of drill core, (which) should be somewhere in the vicinity of 350 diamond drill holes,” said facility manager, Brian Casey.

“Any core that’s stored in here will not be allowed to have any destructive sampling work done to it, so the core has to remain intact at all times. 

“Most of the core that will be stored in here is coming from the mining companies’, from mined-out areas. 

“So it’s classified as ‘historical core’ because some of those areas, once they’re mined-out, (have) nothing more (to) go back to.”

Mr Casey said the stored drill core samples were incredibly helpful for exploration companies to examine or re-examine. 

“Exploration companies, if they take up leases and we hold drill core from those leases, will come and look at that core and re-log it and use their techniques on it,” he said.

“That will help them to plan where they drill some holes on those leases, or (if) they find they (don’t) need to drill holes on those leases they’ve (at least) got sufficient information (about them.)”

The new storage space was already filling up with drill core samples, he said.

“A majority of the core (that is already here) has come from Perilya and CBH,” said Mr Casey.

“We’ve also got some from Cobalt Blue and these mining companies are all on board. Silver City Minerals have donated some drill core to it as well.

“It’s an ongoing program. As we identify areas we’d like to get drill core from we approach the mining companies, and if the area’s not active, they may relinquish some of that core to us. 

“We (also) have several university groups that come through here.

“We’ve actually got Sydney University here...for a week. 

“They’ll be looking at the rock collection we’ve got here and going out into the field and identifying those rocks. 

“And they’ll also be doing a logging exercise on a couple of drill holes.

“So the core comes in here, the majority of it is rehabilitated and put into new plastic trays, marked up and then stored here under cover in good, safe, secure surrounds.”

Deputy Premier John Barilaro “offically opened” the $700,000 upgrade last weekend.
