Asanko Gold Inc. (“Asanko” or the “Company”) (TSX:AGK)(NYSE MKT:AKG) is pleased to provide an update on the Phase 2 Definitive Feasibility Study (“DFS”) for its flagship project, the Asanko Gold Mine in Ghana, West Africa. The DFS was initiated following a positive Pre-Feasibility Study (“PFS”) released in May 2015.

Phase 2 Pre-Feasibility Study

The PFS envisioned integrating the Esaase deposit with Phase 1 to create one large, multi-pit mine and expanding the existing processing facilities to produce an average of 411,000 ounces of gold per annum (“pa”) over a 10.5 year Life of Mine (“LoM”) from 2018. The ore would be mined and crushed at Esaase and then conveyed to the expanded Phase 1 processing facility, which would include an upgrade to the CIL circuit with two extra tanks to increase capacity from 3Mtpa to 3.8Mtpa and the addition of a 5Mtpa flotation plant.

Opportunity for Staged Capital Development

Following the successful commissioning of Phase 1 in Q1 2016, the process plant has demonstrated the ability to operate at greater than 110% of the 3Mtpa design (see news release dated April 6, 2016). This has presented an opportunity to take advantage of the Esaase oxide ore (representing approximately 37% of Esaase reserves) which are well suited to processing through the CIL circuit. Therefore the scope of the Phase 2 DFS has been modified to include a two-stage approach for the integration of the Esaase deposit with Phase 1:

  • Phase 2A: development of the Esaase pit, mining up to 2Mtpa of oxide ores and construction of the conveyor to provide the additional ore to process up to 5Mtpa through the existing CIL circuit, which will be upgraded; and
  • Phase 2B: mining of both Esaase oxide and fresh ores and expansion of the processing facilities to include the addition of a 5Mtpa flotation plant to bring the total processing capacity up to 10Mtpa.

Peter Breese, President and CEO, said: “The successful ramp-up of the Phase 1 processing facility and the additional excess mill capacity has led us to re-think our approach for Phase 2. With a hungry mill and a CIL circuit that can be cost effectively upgraded, we believe staging the development of Esaase is a smarter option that we can fund out of cash flow whilst maintaining our strong balance sheet.

By focusing on mining just the Esaase oxides initially, which will utilize the mill’s spare capacity, we can increase gold production by nearly 50%, thereby reducing our unit cost of production and significantly improving cash flow.

With Esaase about two years away from production, we will look to advance development of the satellite pits as well as continue our near-mine exploration program to find additional resources to keep the mill full until Esaase is brought online.”

Overview of Phase 2A

The Esaase deposit contains 60.3Mt of Proven and Probable Mineral Reserves2 of which approximately 23Mt are oxide and transition ores. Phase 2A will develop the Esaase pit, mining the oxide portion of the Mineral Reserve to provide an additional 2Mtpa of material which will be blended with 3Mtpa of the Nkran fresh ore and processed through the existing processing facility, which will be upgraded.

Development will include construction of mining and crushing infrastructure and a 27km overland conveyor belt to transport the ore to the existing processing facility. Brownfield modifications will upgrade the existing processing plant capacity from 3Mtpa up to 5Mtpa. The upgrades to the processing facility that were originally envisioned to expand capacity from 3Mtpa to 3.8 Mtpa in the PFS are now expected to increase production levels up to 5Mtpa. The extent and cost of the modifications will be detailed in the DFS. Additional metallurgical test work, undertaken at ALS laboratories in Perth, Australia, together with operational experience gained from Phase 1 to date has confirmed that metallurgical recovery from blending of the Esaase oxide and Nkran fresh ores will be in-line with the PFS recovery estimates of approximately 90.9%2.

(2) Based on Phase 2 PFS published on SEDAR June 29, 2015

Based on the PFS capital cost estimate and mine plan, Phase 2A is expected to take approximately 21 months for detailed design and construction at a capital cost of approximately US$100 – 125 million(2). Production of over 280,000 ounces/pa is targeted to commence in Q4 2018. The increase in production by approximately 47% is expected to improve the overall unit operating costs as the fixed cost of operations is spread over a larger production base. The operating and capital cost estimates are currently being updated as part of the DFS, which is due in Q3 2016.

Based on the current gold price environment, the Company is forecasting that it should be able to fund construction of Phase 2A from the cash flow from the existing operations.

Overview of Phase 2B

The second stage of the project, Phase 2B, will expand the mining operation to mine both Esaase oxide and fresh ores and expand the processing facility with the construction of an additional 5Mtpa milling and flotation plant for the exclusive processing of Esaase fresh ores. Production is expected to exceed 480,000 ounces/pa from 2022 onwards, with total processing capacity of 10Mtpa (3Mtpa from Nkran and 7Mtpa from Esaase).

The capital cost is expected to be approximately US$150 – 170 million(3) and development of Phase 2B development will be staggered so that the capital cost will be funded from cash flow.

A Phase 2 Environmental Impact Assessment (“EIA”) was submitted to the Ghanaian Environmental Protection Agency (“EPA”) in June 2015 based on the revised scope for development of the Esaase project from a stand-alone operation.

A Scoping Report and a draft Terms of Reference for the revised project proposal was prepared and submitted to the EPA in August 2015. Following extensive stakeholder engagement, the Company has obtained the necessary support of local stakeholders. This support was formalized in a Public Hearing held by the EPA on April 19, 2016 at which the local stakeholders expressed their desire for Phase 2 to proceed.

A final Environment Impact Statement (“EIS”) is now being prepared and following submission and review, the Company expects to receive its Environment Permit to start construction of Phase 2A in Q4 2016.

Key Milestones and Timelines:

Complete Phase 2 DFS Q3 2016
Receive Environmental Permit Q4 2016
Investment Decision on Phase 2A Q4 2016
Start detail design and Construction Q1 2017
Phase 2A complete Q4 2018
