Marcobre is the sole owner of the Marcona copper property and the Mina Justa project.

The Mina Justa project is the principal exploration and development prospect within the Marcona copper property, and contains a JORC compliant resource of 413.3 million tonnes of ore with 0.79% copper.

Glencore International’s co-director of the Zinc/Copper/Lead department Daniel Mate said Mina Justa will complement Glencore’s existing polymetallic mining operations in Peru, and add significant value to firm’s worldwide group of copper mining assets.

The transaction is expected to be completed in October 2011 and is subject to a number of conditions, including the completion of satisfactory due diligence in respect of the assets by Glencore International.
