Building a mid-tier gold producer

Asanko Gold Mine Global Mineral Reserves

The AGM Mineral Reserve Estimate (“MRev”) was updated as at December 31, 2016 and incorporates a more conservative CSA resource model for the Nkran pit. In April 2017, following the successful Akwasiso infill drilling program which increased reserves and grade, the Akwasiso MRev has been updated.

In addition, the MRev has been modified to reflect new cut-off grades following an NPV optimization exercise that was completed for each pit. This optimization process seeks to determine the best outcome balance between the highest NPV, the maximum ounces produced and the lowest cost per ounce produced per pit. As a result, cut-off grades vary according to ore type. At Nkran, the cut-off grade is now 0.7g/t for fresh ore. At Esaase, 0.6 g/t cut-off is used for all ore. For the satellite deposits, 0.5g/t cut-off is used for oxide ore and 0.7 g/t cut-off is used for fresh ore.

Notes:
Reserves estimated at a forward looking US$1,300/oz gold price.
All figures are rounded to reflect appropriate levels of confidence. Apparent differences may occur due to rounding.
Only Measured and Indicated Mineral Resources were converted to Mineral Reserves.
Nkran includes depletion since February 2015 of 5.08Mt at 1.66 g/t Au for 270,471 ounces, as at December 31, 2016.
Reserves excludes the ROM stockpile of 1.52Mt at 1.36 g/t Au for 66,669 ounces and the marginal stockpile of 0.43Mt at 0.67 g/t Au for 9,121 ounces as at end December 2016

 

Asanko Gold Mine Global Mineral Resources

The Mineral Resource Estimates (“MRE”) for Nkran, Akwasiso and Dynamite Hill have been compiled by independent experts CSA Global, a leading mineral resource consulting group. The MRE for Esaase Main has been compiled by CJM Consulting and audited by CSA Global. The MRE for the remaining satellite deposits is based on the 2014 CJM Consulting estimation. 89% of the AGM MRE has been compiled and/or audited by CSA.

Cautionary Note to US Investors Regarding Mineral Reporting Standards:
Asanko has prepared its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of US securities laws. Terms relating to mineral resources in this press release are defined in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Standards on Mineral Resources and Mineral Reserves. The Securities and Exchange Commission (the “SEC”) permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Asanko uses certain terms, such as, “measured mineral resources”, “indicated mineral resources”, “inferred mineral resources” and “probable mineral reserves”, that the SEC does not recognize (these terms may be used in this press release and are included in the public filings of Asanko which have been filed with securities commissions or similar authorities in Canada).
