Centaurus Metals, a junior Australian com-pany, has filed the environmental impact assessment (EIA) for its Jambreiro iron ore project with the Minas Gerais state envi-ronmental authority in southeast Brazil. The company is targeting approval of the EIA and receipt of a preliminary license for the project during October 2012, in line with its development timetable of produc-ing first iron ore at Jambreiro by the end of 2013. The EIA is for an operation that can deliver up to 3 million mt/y of high-grade iron ore product, although the project is currently planned to start at a production rate of 2 million mt/y.

Domestic Brazilian steel mills are the primary target market for Jambreiro pro-duction. Initial pilot-scale test work on Jambreiro ore has produced a high-grade sinter feed product grading 65.6% iron with low impurities—2.8% silica and 0.01% phosphorus. The work confirmed the effectiveness of a robust, simple, low-cost, two-stage magnetic separation pro-cessing route that allows production of a range of product qualities to suit different customer needs, including a high-grade, low-impurity product that meets the sinter feed blend requirements of traditional steel mills.

Current estimated JORC-compliant resources at Jambreiro stand at 116.5 mil-lion mt measured, indicated, and inferred, grading 26.8% iron. A new resources esti-mate is scheduled for the end of May 2012 as part of a bankable feasibility study that is currently in progress. The new estimate will focus primarily on upgrading the respective categories of the resources, rather than on increasing the overall tonnage.

A diamond drill rig has been mobilized to the Jambreiro project to start a geotech-nical drill program required by the feasibility study.
