Adelaide Resources confirms one big copper system

THE DRILL SERGEANT: Adelaide Resources (ASX: ADN) claims to have confirmed its high-grade Yorke Peninsula copper discoveries to be part of one continuous system.

The revelation has come from Adelaide Resources’ development of a new model for copper mineralisation at the Alford West prospect, part of the company’s Moonta copper gold project, and its satellite target zones including Blue Tongue, to a depth of 130 metres below surface.

“The model has been constructed using all available information from drilling, and incorporates the exploration team’s understanding of the behaviour of metal in the weathered zone and the relationship of copper and gold mineralisation to other metals,” Adelaide Resources said in its ASX announcement.

The company described the key features of the new Mineralisation Model to include interpretation of the Alford West, Blue Tongue and Blue Tongue West targets to be part of a single, large iron oxide copper-gold style mineralised system that extends over three kilometres.

Four internal zones have been highlighted within the broader system, which Adelaide Resources considers could potentially contribute to a mineral resource.

These are named Larwood, Bruce, Six Ways and Blue Tongue and all four zones remain open at depth.

“The dimensions of the currently modelled lodes confirm that potential for a substantial mineral resource exists, if deeper exploratory drilling successfully demonstrates the mineralised zones persist to depth,” the company said.

“Very limited historical diamond and RC drilling at Alford West has intersected deeper mineralisation and returned primary zone intersections in excess of one per cent copper, highlighting the potential for attractive grades of mineralisation to persist to depth.”

Adelaide Resources said its confidence in the depth potential at Alford West had been enhanced by the lateral extent of the system, the presence of significant mineralisation at depth at the nearby Wombat prospect, and the typically deep extent of other deposits in the district.

The company has already put the new information to use in designing a recently completed aircore drilling program at the Larwood and Bruce zones to target additional shallow mineralisation.

Assaying of these holes is in progress however, however the company stated FPXRF scans of drill samples suggest mineralised intervals are present confirming the model’s predictive ability.

“The new model now enables the confident design of deeper drilling to test for depth extensions and establish a mineral resource at Alford West,” Adelaide Resources said.

“The model will be revised to incorporate new and deeper drill information when it comes to hand, and will form the basis for ore resource estimation for Alford West.”
