Birla Mt Gordon Operation

Overview

The Mt Gordon operation is located in northwest Queensland, approximately 120 km north of Mt Isa.

Background

Copper oxide mineralisation was first discovered in the district at Mt Oxide in 1882, followed by the discovery of the Mammoth deposit in 1927. This was intermittently worked on a small scale until 1969, with copper in concentrate and copper cathode produced from the Mammoth deposit between 1969 and 1995.

Aberfoyle purchased the operation in 1995 and delineated the Esperanza deposit before being acquired by Western Metals Limited in 1998. Aditya Birla Minerals acquired the operation in November 2003.

Geology

The Mt Gordon project area lies on the Mt Gordon fault zone, a major fault separating the metasedimentary rocks of the Mt Isa sequence from the younger metasediments to the west.

Notes

  1. Ore reserves and mineral resources have been estimated as at 31 March 2009 by Aditya Birla Minerals and classified and reported according to the JORC Code (2004). Totals may not add due to rounding.
  2. Ore reserves are generally based on a copper cut-off grade of 1.5%; however minor individual lower grade stopes are included in the overall reserve.
  3. Mineral resources are inclusive of ore reserves.

Mt Gordon Operation

Mining operations are focused on the Mammoth underground mine, following the exhaustion of the Esperanza open pit in November 2005. The Esperanza South Decline was in development before the operations went into care and maintenance.

The operation is set up to produce copper in concentrate through a standard flotation plant and BioteQ technology from accumulated acid drainage. Due to currently available ore sources which are more amenable to concentrate production, copper cathode operations consisting of a ferric leach plant and SX-EW were suspended in January 2006.

Copper in concentrate is trucked to Cloncurry, railed to Townsville and then shipped to Hindalco Copper’s Dahej copper smelting and refining facility in India. Copper in concentrate produced is sold to Hindalco under a LOM off–take agreement based on arm’s length terms.

The Mt Gordon Operation is currently under care and maintenance and an evaluation of its re-opening feasibility is in progress.

Mt Gordon has an estimated mineral resource of approximately 549 kt of copper. The majority of this mineral resource occurs at Mammoth, within the Esperanza system below the present open pit or within the standalone Esperanza South resource. Discoveries at depth of the Mammoth resource were made. Studies are under way to evaluate the potential of converting those resources into reserves by optimising the undergrounds haulage and cost profile.
