FOOTNOTES RELATED TO RESERVE & RESOURCE ESTIMATES
Detailed footnotes related to Mineral Reserve Estimates (dated December 31, 2017)
(1) CIM definitions (2014) were followed in the calculation of Mineral Reserves.
(2) Mineral Reserves were estimated using a long‐term gold price of US$1,280/oz (C$1,600/oz; A$1,600/oz).
(3) Cut‐off grades for Canadian Assets were calculated for each stope, including the costs of: mining, milling, General and Administration, royalties and capital
expenditures and other modifying factors (e.g. dilution, mining extraction, mill recovery.
(4) Cut‐off grades for Australian Assets from 0.4 g/t Au to 3.0 g/t Au, depending upon width, mining method and ground conditions; dilution and mining
recovery factors varied by property.
(5) Mineral Reserves estimates for the Canadian Assets were prepared under the supervision of P. Rocque, P. Eng.
(6) Mineral Reserves estimates for the Fosterville property were prepared under the supervision of Ion Hann, FAusIMM.
(7) Mineral Reserves estimates for the Northern Territory property were prepared under the supervision of Russell Cole, FAusIMM.
(8) Mineral Reserves for Fosterville relate to Underground Mineral Reserves and do not include 649,000 tonnes at an average of 7.7 g/t for 160,000 ounces of
Carbon‐In‐Leach Residues – 25% recovery is expected based on operating performances.
(9) Totals may not add exactly due to rounding.
Detailed footnotes related to Mineral Resource Estimates for Canadian Assets (dated December 31, 2017)

guidelines.
(3) Mineral Resource estimates were prepared under the supervision of D. Cater, P. Geo. Vice President Exploration Canada.
(4) Mineral Resources are estimated using a long‐term gold price of US$1,280/oz (C$1,600/oz).
(5) Mineral Resources were estimated using a 8.6 g/t cut‐off grade for Macassa, a 2.9 g/t cut‐off grade for Holt, and a 2.6 g/t cut‐off grade for Taylor, a 3.9
g/t cut‐off grade (Holloway), a 2.5 g/t cut‐off grade for Canamax, Card, Runway and Ludgate, a 2.2 g/t cut‐off grade for Hislop and 0 g/t cut‐off grade for
Aquarius.
(6) Totals may not add up due to rounding.
Detailed footnotes related to Mineral Resource Estimates for Australian Assets (dated December 31, 2017)
(1) CIM definitions (2014) were followed in the estimation of Mineral Resource.
(2) Mineral Resources are estimated using a long‐term gold price of US$1,280/oz (A$1,600/oz)
(3) Mineral Resources for the Australian assets are reported exclusive and inclusive of Mineral Reserves to allow for meaningful comparison to prior
periods.
(4) Mineral Resources at Fosterville were estimated using cut‐off grades 0.7 g/t Au for oxide and 1.0 g/t Au for sulfide mineralization to potentially open‐
pitable depths of approximately 100m, below which a cut‐off grade of 3.0 g/t Au was used.
(5) Mineral Resources in the Northern Territory were estimated using a cut‐off grade of 0.5 g/t Au for potentially open pit mineralization and cut‐offs of 1.0
to 2.0g/t Au for underground mineralization.
(6) Mineral Resource estimates for the Fosterville property were prepared under the supervision of Troy Fuller, MAIG.
(7) Mineral Resource estimates for the Northern Territory properties were prepared under the supervision of Mark Edwards, FAusIMM (CP).

Cautionary Note to U.S. Investors ‐ Mineral Reserve and Resource Estimates
All resource and reserve estimates included in this news release or documents referenced in this news release have been prepared in accordance with Canadian National Instrument 43‐101 ‐ Standards of
Disclosure for Mineral Projects ("NI 43‐101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") ‐ CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by
the CIM Council, as amended (the "CIM Standards"). NI 43‐101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific
and technical information concerning mineral projects. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI
43‐101 and the CIM Standards. These definitions differ materially from the definitions in SEC Industry Guide 7 ("SEC Industry Guide 7") under the United States Securities Act of 1933, as amended, and the
Exchange Act.
In addition, the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43‐101 and the CIM
Standards; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the U.S. Securities and
Exchange Commission (the "SEC"). Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a
great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be
upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre‐feasibility studies, except in very limited circumstances. Investors are
cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve or is or will ever be economically or legally mineable or recovered.
