RNINL said May 9 that drilling has started at the Cuba copper-goldprospect within its Doolgunna copper project in Western Australia.

As the company announced in April, the drill program at Cuba willcomprise up to eight reverse circulation holes to a depth of about 450 metersto target the target's prospective volcanic hosted massive sulfide horizon,which is proximal to SandfireResources NL's DeGrussa and Monty copper-gold discoveries.

The holes will also provide a platform for follow-updownhole electromagnetic surveys on the prospects' targeted copper-goldmineralization.

According to RNI, the drilling and the downholeelectromagnetic surveys at Cuba are expected to take up to five weeks to becompleted, while the assays and geochemical analysis will take a further four weeks.
