Sunstone Metals Identifies Ecuadorian Drill Targets

THE DRILL SERGEANT: Sunstone Metals (ASX:STM) reported the defining of large drilling targets from 3-D modelling of heli-magnetic data results taken at the company’s Bramaderos gold-copper project in Ecuador.

Sunstone Metals said this was the first 3-D modelling of a subset of recently collected heli-magnetic data over the Bramaderos Main and nearby targets and demonstrated these targets have considerable vertical extent.

The company currently has 3-D modelling of the Limon and West Zone targets underway with results expected shortly.

The company explained that a large magnetic body has been modelled at Bramaderos Main with a vertical depth of one kilometre and a surface expression that coincides with the areas of best historical drilling and gold anomalism defined by a recent trenching program.

Historical drill hole CURI03, and recent trench BM02, both intersected widths of gold and copper mineralisation and the recent model indicates the main magnetic area has not been drill tested and occurs just beyond the highest assay results from historical hole CURI03, which included 30.2 metres at 0.8 grams per tonne gold and 0.2 per cent copper at the bottom of the hole.

Sunstone said the modelling also enhanced the Porotillo target by providing context for areas of gold-in-soil anomalies, and historical drilling which it appears may have been drilled on the periphery of the magnetic target zone.

The Porotillo target is located 1.5km south of Bramaderos Main and was previously considered a lower-ranked target due to historical drilling that delivered sporadic gold mineralisation.

However, this 3-D modelling has defined a large magnetic body, which evolves near surface into a cluster of magnetic bodies – a magnetic pattern is seen in other porphyry systems.

“The 3-D modelling results provide more strong evidence of the huge potential of the Bramaderos Main and Porotillo targets,” Sunstone Metals managing director Malcolm Norris said in the company’s announcement to the Australian Securities Exchange.

“The modelled magnetic bodies sit adjacent to, and extend below, the drill holes which intersected copper and gold, and are located below the extensive gold anomaly we have outlined.

“This work increases our confidence yet again in the robustness of the targets and starts to deliver a sense of scale to these targets.

“Additional 3-D modelling is currently underway over the Limon and West Zone targets.”
