Miraflores Feasibility Study Delivers Positive Findings



Metminco Limited (ASX: MNC, AIM: MNC) ("Metminco" or the "Company") is pleased to announce the completion of the Feasibility Study into the development of its Miraflores Gold Project in Colombia, which has further demonstrated the financial and technical viability of the proposed operation.



  • Feasibility Study confirms Miraflores Gold Project as financially robust and technically sound;
  • Average annual production of 45,000 ounces of gold and 22,600 ounces of silver over approximately 9.5 years;
  • Total forecast capital cost of US$71.8 million (excluding contingency of 7.67%), with an additional US$18.5 million in sustaining capital required over life-of-mine (LOM);
  • Estimated LOM cash operating costs of US$599 an ounce and LOM all-in sustaining costs of US$643 an ounce;
  • Estimated LOM undiscounted free cash flow of US$150 million (using US$1,300/oz gold price);
  • Net Present Value of US$72.3 million (after tax, 8% discount rate) and Internal Rate of Return of 25% (after tax).
  • Maiden Ore Reserve Estimate

  • 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.



As part of the study, Metminco has declared a maiden NI 43-101 and JORC 2012-compliant Ore Reserve for Miraflores of 4.326Mt grading 3.29g/t gold for 456,000 contained ounces.


Over that period, the Miraflores plant would process 4.326 million tonnes of ore grading an average of 3.29g/t Au and 2.56 g/t Ag for total production of 421,241 ounces of gold and 210,815 ounces of silver (an average of approximately 45,000 ounces of gold and 22,600 ounces of silver per year).


The initial capital cost of developing the mine and associated infrastructure has been estimated at US$71.8 million excluding contingency. Contingency is approximately US$6.1 million. An additional US$18.5 million in sustaining capital is expected to be required over the life-of-mine (LOM).


LOM cash operating costs have been estimated at US$599/oz, while LOM all-in sustaining costs have been estimated at US$643/oz, which would position Miraflores in the first cost quartile of gold operations globally.


Applying a US$1300 gold price, which was used for all base-case financial modelling in the Feasibility Study, Miraflores delivers LOM free cash flow of US$150 million, a Net Present Value at an 8% discount rate of US$72.3 million and an Internal Rate of Return of 25% (all measures are on an after-tax basis).


Mr William Howe, Managing Director, said: "We are delighted with the positive Feasibility Study outcome which is further vindication of the Company's decision to pursue an underground-only development option at Miraflores as a means of reducing capital costs and shrinking the mine footprint. The Study delivers robust returns and with this now in hand, we can focus on arranging the required finance and securing the outstanding approvals in order to be in a position to make a decision on development in a timely manner."

The Miraflores Feasibility Study did not take into account any upside that may result from exploration at the nearby Chuscal and Tesorito prospects, where the focus is on defining more resources in high-grade vein systems that could also be mined using underground methods.

Metminco engaged GR Engineering Services Limited (GRES), an Australian firm with extensive experience in designing and building gold projects globally, to manage the Feasibility Study. GRES subsequently engaged GMI, an arm of Peru-based Grana Y Montero Group to provide it with engineering design services. Dynami Consulting, which is based in Medellin, Colombia, provided geotechnical engineering and design services.

Metminco would like to thank these companies and the other contractors and consultants that contributed to the Feasibility Study for their professionalism and hard work.

A separate announcement including further details relating to the findings from the Feasibility Study will be released in due course.
