Asanko gold mine, Ghana
Name and Location
Asanko gold mine, Ghana.
Client
Asanko Gold acquired the Obotan project during a C$183-million takeover of PMI Gold Corp in February 2014.
Project Description
The Asanko mine was created by combining the Obotan and Esaase projects into one project, which will be developed over two phases.
The Asanko mine has 7.5-million ounces of measured and indicated resources, including 4.8-million ounces of proven and probable reserves.
Phase 1 of the Asanko mine is based on PMI Gold's definitive feasibility study (DFS) for the Obotan project, published in September 2012.
The DFS targeted an estimated 2.25-million ounces of gold production over an 11.5-year life-of-mine, using an openpit contractor mining operation and a three-million-tonne-a-year carbon-in-leach processing plant. The primary source of feed material for the carbon-in-leach plant is the Nkran pit, with satellite pits at Adubiaso, Abore and Asuadai, and the recently discovered Dynamite Hill deposit providing supplemental feed.
Phase 2 anticipates the inclusion of the adjacent Esaase deposit, which is located only 25 km from the plant site. A scoping study is under way to evaluate the optimum ore transport method and the scope of the plant expansion. The study is scheduled for publication in the second quarter of 2015. Phase 1 has incorporated sufficient plant terracing and designed the plant layout and infrastructure to cater for the potential of Phase 2.
Value
The Obotan DFS estimated capital costs of $296.6-million.
Since acquiring PMI Gold earlier this year, Asanko Gold has updated the capital cost estimate to a higher level of accuracy suitable for use as a project control budget estimate (CBE). The CBE estimates a capital cost for Phase 1 of $295-million, including contingency for estimating inaccuracy and owner's contingency. The capital estimate is generally considered accurate to +/- 5%.
The CBE was designed on a modular basis to cater for the possible inclusion of Phase 2 on the same site.
Duration
Phase 1 construction started in the third quarter of 2014, with first gold targeted in the first quarter of 2016 and steady-state production of 200 000 oz/y of gold expected in the second quarter of 2016.
Latest Developments
Early works at the project site started in April and the Asanko board approved the construction of Phase 1 of the Asanko gold mine during the third quarter. Ground breaking took place in August 2014.
Asanko is updating the mineral resource estimate for Phase 1, which it plans to publish by the last quarter of the year, along with a definitive project plan.
With the project fully permitted, financed and a team of experienced mine builders and operators in place, Asanko has said that it will, in parallel with construction of Phase 1, evaluate the optimal way to implement Phase 2 to bring to account the additional 2.2-million ounces of reserves at Esaase, while capturing the synergies between the two deposits.
