Marillana shows its metal

SHARES in Brockman Resources have gained ground on the back of a maiden ore reserve for its flagship Marillana project, the fourth-largest published haematite reserve in Western Australia’s Pilbara region outside the big three producers, according to the iron ore play.

The Perth-based company announced a detrital ore reserve estimate of 1.05 billion tonnes grading at 42.4% iron for the project, of which 868 million tonnes at 42.5% iron is in the probable category and more than 133Mt at 41.6% iron is in the proven category.

The detrital ore is expected to produce 378Mt of final product grading at 60.5-61.5% iron with impurity levels comparable with other WA direct shipping hematite ore (DSO) iron ore producers.

An additional channel iron deposit (CID) probable ore reserve of greater than 48Mt at 55.5% iron has also been defined. This ore is a DSO product that will be blended with the detrital product for export as a single product.

Brockman expects Marillana to produce more than 426Mt of final DSO equivalent product which, at current prices, will generate revenues greater than $A50 billion.

The reserve supports a long-term mine life of up to 25 years at a nominal production rate of 17-20Mtpa.

Brockman managing director Wayne Richards told MiningNews.net the Marillana reserve was the largest published haematite ore reserve in the Pilbara outside the three major producers – BHP Billiton, Rio Tinto and Fortescue Metals Group.

“The size of the reserve is only second to the three majors in the Pilbara and obviously the strength is that it is all in one location,” he said.

“It’s one continuous mine and one continuous pit in one geographical location which is 300 kilometres from the port of Port Hedland and is a shorter training distance than most of the major mines. The only one I think that is closer is FMG’s Cloudbreak which is a little closer to the port at around 180 kilometres.”

Richards said the majority of the work towards the definitive feasibility study had now been finished with the company on track to release the final results of the study later this month.

“[Marillana is] well located, it’s continuous, we have proved the ore is upgradeable, we have done the sintering tests, its marketable, we have done the agreements with Sinosteel so it’s a good project, and obviously its finalising logistics around port and rail now,” Richards said.

Brockman has completed process design and engineering of the preferred process route while pricing of major equipment packages has been factored into the capital cost estimates.

Financial modelling based on the DFS capex and opex estimates has begun to determine the financial parameters of the project delivery strategies.

The pit optimisation, open pit design and definitive mining schedule have now been optimised, as part of the development of the Marillana ore reserve.

The project is scheduled to begin mining in late 2013 at a rate of 17-20Mtpa.
