Macquarie Harbour Mining Reveals Alcoa To Visit Slag Project In October

Macquarie Harbour Mining's (ASX:MHM) Aluminium Salt Slag Project, located in Moolap Victoria, continues to provide robust monthly revenue during a technology upgrade, operated by wholly-owned subsidiary Alreco Pty Ltd.

August gross revenues were $511,824, slightly down from the July $521,648, with the technology upgrade well advanced and remaining on budget.

Due to regulatory changes by the EPA this material can no longer be disposed in landfill, and with Alrecos proprietary technology, the ALNAK technology, Salt Slag can be processed and separated into its individual components of aluminium metal (10-20%), aluminium oxide (30-40%) and a salt and potassium chloride blend (50%).

The technology results in total waste treatment and production of aluminium and other saleable products.

The company said its negotiations with smelters in the United States are ongoing and strengthening, with a number of parties now positively engaged in discussions for Salt Slag processing.

Senior representatives of Alcoa, Inc (USA) will be visiting the Alreco operation during October with a view to furthering discussions for operations in the United States.

Investors were impressed with the Macquarie news, pushing the stock up from $0.245."
