Assays from resource drilling at the high priority Mt Flora prospect within the Bundarra copper project area in central Queensland have doubled the areas of copper and silver mineralisation for owner Duke Exploration (ASX: DEX).

The company confirmed today that results had been received from the first complete line of a post-Christmas reverse circulation program comprising 34 holes for a total 6,271m from a budget of 43 holes for 7040m.

Best intercepts were 6m at 1.39% copper, 29.4 grams per tonne silver and 0.03g/t gold from 51m (underground mine lode); 3m at 2.71% copper, 11.9g/t silver and 0.31g/t gold from 100m; 17m at 1.12% copper, 11.4g/t silver and 0.13g/t gold from 55m; and 16m at 1.17% copper, 10.5g/t silver and 0.08g/t gold from 84m.

The newly-discovered Quarry anomaly returned Mt Flora’s highest grades to date and will contribute to the prospect’s growing resource potential.

Better understanding of Mt Flora mineralisation

Duke chairman Toko Kapea said the recent assays had more than doubled the mineralised area at Mt Flora and the company now has a better understanding of the geometry of the prospect’s massive sulphide copper and silver veins and their spatial relationship to the granodiorite.

“We are very happy with the results from the first line of resource drilling,” he said.

“They have confirmed our initial interpretations based on historic data and have more than doubled the mineralised area both down dip and to the west.”

He said the next phase of drilling would focus on Quarry.

Drilling lines

Three lines of drilling have now been completed at Mt Flora over a known mineralised area covering a 200m strike, 250m width and a 280m vertical depth.

A total of 7,000 samples have been sent to a Townsville laboratory and 4,222 assay results returned to date.

The results feature approximately 73 intersections of copper, silver and gold mineralisation above a 0.2% copper cut-off with consistency of width, grade and orientation between holes.

Duke is chasing an exploration target at Mt Flora of between 5.5-12Mt at up to 0.7% copper for between 27,000-84,000t of copper; up to 15g/t silver for 884,000-5.7Moz silver; and 0.1g/t gold for up to 38,000oz.
