In addition, the increase in the rate of the production of these nanostructures and reducing the production cost will be possible due to the high accuracy and sensitivity of the method in the creation of gold nanoparticles and the prevention of formation of gold oxide during and after the process.

The A Zone prospect consists of strata-bound volcanogenic massive sulphide (VMS) mineralization systems with a demonstrated gold oxide layer of 40 meters (130 feet) to 60 meters (200 feet), as well as a copper-enriched supergene extending from the bottom of the gold oxide layer to depth of 100 meters (330 feet).

Because the Buen Futuro gold oxide ore is relatively soft and broken due to the nature of the deposit and the tropical humidity, the company believes that one of the 1,000 hp ball mills alone will provide the 3,500-tpd capacity in the gold circuit, while the rest of the grinding capacity can be used in the copper circuit.
