Kinross expects to finance both projects with its strong balance sheet and existing liquidity, and operating cash

flows. As of June 30, 2017, Kinross had cash and cash equivalents of $1,061.3 million , and available credit of

$1,433.1 million, for total liquidity of approximately $2.5 billion. Kinross also has no debt maturities prior to 2021 .

Maintaining balance sheet strength and financial flexibility continue to be top priorities as the Company develops

both projects.

The Phase Two and Phase W feasibility studies have been reviewed by third-party independent reviewers and were

found to be consistent with industry best practices.

CEO commentary

J. Paul Rollinson, President and CEO, made the following comments in relation to the Tasiast Phase Two and Round Mountain Phase W projects:

“Our decision to proceed with the Tasiast Phase Two expansion underscores our determination to realize the

potential of this world -class asset and generate significant value for our shareholders. Our continued focus on

financial discipline and technical excellence has resulted in lower capital requirements than originally forecast, which

would materially improve project IRR and NPV.

“With Phase Two, Tasiast’s annual production is expected to increase to more than 800,000 gold ounces per year

for the first five years and significantly reduce costs. This strong improvement in Tasiast’s performance is expected

to positively impact overall company performance metrics, strengthening our production profile and increasing cash

flow.

“We have applied the same financial and technical rigour to the Phase W expansion at Round Mountain. Lower

operating costs, combined with an optimized mine plan, have contributed to a further de -risking of the project and

improved returns. Phase W is expected to add five years of mining at one of our best performing operations.

“We are delivering on our strategy while opening a new chapter as we invest in our long -term future growth. In

short, this is great news for our shareholders.”

Tasiast Phase Two overview

The Phase Two feasibility study contemplates installing additional mill throughput of 18,000 t/d to the Phase One

project’s 12,000 t/d capacity for a total combined capacity of 30,000 t/d.

Initial plant and infrastructure capital costs for the additional 18,000 t/d expansion are forecast to be $590 million,

which is lower than the pre -feasibility estimate of $620 million . The combined Phase One and Phase Two non-

sustaining capitalized stripping is expected to be $370 million from 2018 through the first half of 2020.

The Phase Two project is expected to generate significant positive economic benefits for Mauritania and its people

through additional taxes, duties, wages and locally supplied goods and services. The Company is appreciative of

the support of the Government of Mauritania during its seven years of operation in the country, and it continues to

maintain a cooperative and constructive relationship with the Government and other local stakeholders . Major

permitting for the Phase Two expansion has been completed.

“We support the Kinross decision to proceed with the Tasiast Phase Two expansion and the additional investment

and long-term benefits the project will bring to the country and our people,” said Mauritania’s Minister of Petroleum,

Energy & Mines Mohamed Abdel Vetah.

The completed Phase Two fe asibility study reaffirms the previous pre -feasibility study results and has factored in

recent improvements at Tasiast – including productivity improvements, lower input prices and increased throughput

at the existing mill – to increase confidence in the feasibility study assumptions, lower execution risk, and generate

a robust internal rate of return.

The expansion would replace the two current ball mills with a new larger ball mill, and add new leaching, thickening

and refinery capacity and additions to the mining fleet. A new power plant would be added to power the 30,000 t/d

mill, which is forecast to have an average production of approximately 812,000 Au oz. per year for its first five years

Based on an assumed gold price of $1,200/oz. and oil price of $55/bbl, the Phase Two expansion has an estimated

incremental IRR of 24%, and the combined two -phased expansion has an NPV of $1.43 billion (after tax and

unlevered, from January 1, 2018 forward ). The two-phased expansion is expected to generate $2.2 billion in free

cash flow after tax over the life of mine.

With the go-ahead decision for Phase Two, a project team has been established and advanced engineering has

begun. Procurement of critical work equipment packages is advancing, as the construction period is expected to

commence by early 2018, with Phase Two commercial production expected in Q3 2020.

Tasiast Phase One update

The Tasiast Phase One project continues to progress well , being on time and on budget, with full commercial

production expected in Q2 2018 . Plant construction is now two-thirds complete. The SAG mill is now in place and

work has begun on the installation of its gearless motor drive. M echanical installations at the crusher, conveyor,

stockpile and in the existing plant are proceeding well. The oxygen plant has been commissioned and is supporting

the mine’s current production, and the new tailings storage facility is expected to be operational shortly.

Round Mountain Phase W overview

The Round Mountain Phase W feasibility study contemplates a layback of the current pit, construction of a new

Carbon in Column (CIC) plant and heap leach pad, additions to the mining fleet and equipment, and relocation of

some existing infrastructure. Stripping of Phase W ore is expected to begin in early 2018, pending the permitting

process, which is proceeding on schedule. Construction and relocation of infrastructure is expected to be completed

by Q2 2019, and initial low grade Phase W ore to be encountered in mid-2019.

Phase W is expected to add 1.5 million Au oz. to the life of mine plan and generate an incremental IRR of 13% and

incremental NPV of $135 million based on a $1,200/oz. gold price and $55/bbl oil price (after tax and unlevered ,

from January 1, 2018 forward) . Phase W is expected to generate incremental cash flow of $265 million, extend

mining by five years from 2020 to 2024, and sustain the operation’s annual production at an average of

approximately 341,000 Au oz. through 2024, at an average cost of sales of $765 per Au oz. The initial capital costs

are forecast to be $230 million, plus incremental non-sustaining capitalized stripping of $215 million (2018 -2020).

Life of mine sustaining capital is expected to be $135 million.

The Phase W feasibility study has optimized the project plan by finding efficiencies to lower the cost structure. First,

the operational team lowered mining, processing and G&A costs at the current operation through continuous

improvement initiatives, directly benefitting the project mine plan. Second, after the Company acquired the 50% of

Round Mountain it did not already own, the project team completed approximately 115,000 feet of infill, metallurgical

and geotechnical drilling and rebuilt the Phase W geology model based on drilling results and historical production,

substantially increas ing the team’ s understanding of the deposit . Third, through mine plan optimization and

geotechnical analysis, a larger mineral inventory, now approximately 2 .0 million gold ounces compared with 1.3

million gold ounces in the 2016 scoping study, was included in the project. This increase includes higher grade

ounces at the bottom of the pit.

With the go -ahead decision for Phase W, procurement activities for long lead items and mining equipment ha ve

commenced, along with advanced engineering. Additional state and federal p ermitting for the project is required

and is proceeding as planned.

Mineral reserves and mineral resource estimates5

As a result of the Phase W feasibility study, estimated proven and probabl e mineral reserves at Round Mountain

increased from 1.3 million Au oz. (as of December 31, 2016) to 2.8 million Au oz. This incorporates mining depletion

of approximately 400,000 Au oz. from January 1, 2017 to July 31, 2017. The estimated mineral resource decreased

from approximately 3.8 million Au oz. to 3.7 million Au oz. This change is the net of the 2.0 million Au oz. that were

converted from mineral resources to mineral reserves offset by the addition of the 1.9 million Au oz. of new mineral

resources.
