Metminco Limited (ASX: MNC, AIM: MNC) ("Metminco" or the "Company") is pleased to announce the details of the feasibility study technical findings for the development of its Miraflores Gold Project in Quinchia, Department of Risaralda, Colombia (the "Project").

HIGHLIGHTS 

· Maiden Ore Reserve Estimate; Metminco has declared a maiden NI 43-101 and JORC 2012-compliant Ore Reserve for Miraflores of 4.326Mt @ 3.29g/t Au for 456,000 contained ounces of gold.

· The Company announced in September 2017 that it had received approval from the Corporacion Autonoma Del Risaralda (CARDER), the environmental agency in the Department of Risaralda, Colombia, to construct up to 2,000 metres of underground development under the Company's existing Plan De Manejo Ambiental (PMA). The Company is assessing options for funding the underground development.

· With the granting of this permit the Company now has the option to commence underground development of the mine which Metminco believes would provide valuable technical details of the orebody ahead of a decision to proceed with construction of the plant and infrastructure. The permit provides for placement of waste on surface and allows for surface discharge of water from the mine.

· The processing plant has been designed to operate at a treatment rate of 1,300tpd. Detailed metallurgical testwork has demonstrated recoveries of 92% and 60% for gold and silver respectively.

· The After Tax NPV (8% DR), IRR and Payback for the base case are US$72.3 million, 25% and 3.6 years respectively (NPV at 5% DR is US$96.1 million)

· It is envisaged that the project will be constructed over an 18 month period from the commencement of detailed engineering (1 March 2018 commencement date). The early definition of major equipment such as mills, crushers, thickening and filtering equipment is critical for maintaining the project timeline and will be undertaken in a 3 to 4 month front end engineering design (FEED) phase prior to project full commencement. Commencement of site works is subject to EIA approval.

Mr William Howe, Managing Director, said: "The outcome of the feasibility study is testament to the professionalism and dedication of the feasibility study team. The extensive experience of the individuals is demonstrated by the innovative thinking that has culminated in a low cost, fit for purpose mining and processing project."
