Metminco Regulatory News (MNC)

Company Background

Metminco is a dual ASX and AIM listed company with a portfolio of copper, molybdenum and gold projects in Peru and Chile.

Premier project - Los Calatos copper-molybdenum project

In March 2013 the Company announced the results of an independent Scoping Study on Los Calatos. The study confirmed the potential of Los Calatos as a long-life (+31 years), low cost (US$1.09/lb) mining operation producing approximately 83kt (184mm lbs) of copper in concentrate per annum.

The preferred mining scenario evaluated as part of the Scoping Study provides for an open pit with a life of 7-years, and a subsequent underground block cave operation with a life of 24-years, with an average life of mine production rate of 60,000 tonnes per day.

In addition, the prospectivity of the broader tenement holding position is such that it has the potential to contribute additional material to any future mining operation developed in context of the preferred mining scenario. The Company has only drill tested two of the eight targets identified to-date over a total project area of 224 km², where the latter is located in a recognised mining district characterised by the development of porphyry clusters.

Peru is proving to be an investment friendly jurisdiction, in which the Government is actively encouraging responsible mine development with a projected, significant, increase in long term copper production supported by competitive power costs. Mining investment in Peru over the period 2012 to 2020 is estimated to be US$53 billion, of which 70% relates to new copper mines, and extensions to existing mines. Los Calatos remains highly deliverable, being located on State-owned land in a desert environment without competing land usage, its status as Project of National Interest, and its proximity to existing infrastructure and the coast. Metminco's strategy to access seawater for metallurgical processing purposes has been widely accepted by both local and regional authorities.

From a commodity perspective, the long-term fundamentals of the copper market remain sound, and it is anticipated that global copper production will struggle to keep pace with demand growth. With the support of a funding partner, Los Calatos has the ability to deliver copper into the global market at a time when incremental supply-demand dynamics will be dictated by production emanating from new 'possible' projects, the success of which will be heavily influenced by factors such as socio-political issues, restrictive legislation and technical issues (e.g. unit operating costs). Against the global backdrop of diminishing long life copper projects in mining friendly jurisdictions, and with the benefit of low unit operating costs, Los Calatos is well placed to command significant strategic interest.

Projects and mineral resources

The Los Calatos Project, located in southern Peru, has an open pittable mineral resource of 304 million tonnes at 0.44% CuEq at a cut-off grade of 0.15% CuEq to a vertical depth of 500 metres below surface and an underground bulk mining mineral resource of 1,058 million tonnes at 0.61% CuEq at a cut-off grade of 0.35% CuEq commencing at an elevation of 2,500 metres (approximately 500 metres below surface).

The Chilean assets include the Mollacas Project with a mineral resource of 34.3 million tonnes consisting of a measured resource of 19.4 million tonnes at 0.45% Cu and 0.16g/t Au, an indicated resource of 9.4 million tonnes at 0.34% Cu and 0.16g/t Au, and an inferred resource of 5.5 million tonnes at 0.26% Cu and 0.15g/t Au (at a 0.2% copper cut-off); and the Vallecillo Project with a mineral resource of 8.9 million tonnes consisting of a measured resource of 5.5 million tonnes at 0.84g/t Au, 9.99g/t Ag, 1.12% Zn and 0.32% Pb, an indicated resource of 2.6 million tonnes at 0.80g/t Au, 10.23g/t Ag, 0.94% Zn and 0.35% Pb and an inferred resource of 0.8 million tonnes at 0.50g/t Au, 8.62g/t Ag, 0.48% Zn and 0.17% Pb (at a cut-off grade of 0.2g/t Au).

The Company also has a number of early stage exploration projects where initial exploration activities have identified anomalous copper, molybdenum and gold values.

Note: Copper equivalent (CuEq) for Los Calatos is based on the recovered value of the non-copper by-products (molybdenum) relative to the recovered value of copper. At a long term copper price of US$2.75/lb with a Cu recovery of 87% and a molybdenum price of US$15.00/lb with a recovery of 68%, 1 pound of molybdenum is equivalent to 4.2633 pounds of copper (Cu:Mo ratio of 1:4.2633).
