Newmont Declares Commercial Production at Subika Underground in Ghana

DENVER–(BUSINESS WIRE)–Newmont
Mining Corporation (NYSE: NEM) (Newmont or the Company) has achieved
commercial production at the Subika Underground project, adding
higher-grade, lower-cost gold production at the Ahafo mine in Ghana.
Subika Underground represents Newmont’s third profitable expansion in
2018 and its tenth completed project since 2013. Subika Underground was
delivered on schedule and within budget for approximately $186 million
in development capital.

Beginning in 2019, Subika Underground will add average annual gold
production of between 150,000 and 200,000 ounces per year for the first
five years and has an initial mine life of around 10 years. Combined
with completion of the Ahafo Mill Expansion project expected in the
second half of 2019, Ahafo’s average annual all-in sustaining costs
(AISC)¹ are projected to improve by between $250 and $350 per
ounce compared to 2016. The project has an expected Internal Rate of
Return of more than 20 percent.

“In addition to increasing gold production and lowering costs at Ahafo,
Subika Underground leverages the operation’s existing infrastructure and
experienced workforce to further extend mine life,” said Gary Goldberg,
Chief Executive Officer. “The mine provides an underground platform to
explore additional upside potential in adjacent ore bodies and also
includes some of the latest fit-for-purpose technologies to enhance
safety, productivity and efficiency.”

As the Company’s newest mine, Subika Underground features
semi-autonomous loading operations, proximity detection for vehicles,
personnel tracking, and planned installation of ventilation-on-demand
systems.

Over the last five years, Newmont has successfully built 10 new mines
and expansions on four continents – on or ahead of schedule and at or
below budget. These projects include Akyem and the Phoenix Copper Leach
in 2013, the Turf Vent Shaft in 2015, Merian and Long Canyon in 2016,
the Tanami Expansion in 2017, and Twin Underground and Northwest Exodus
in 2018. The Company also completed a value-accretive acquisition of
Cripple Creek and Victor in 2015 and delivered a profitable expansion at
the mine in 2016.

¹ AISC or all-in sustaining cost
improvement as used in this press release are forward-looking non-GAAP

reclamation costs (including operating accretion and amortization of

R&D, treatment and refining costs, other expense, net of one-time
adjustments and sustaining capital. Expected improvement to Ahafo’s
costs applicable to sales is expected to be $150 to $250 per ounce for
the comparison period. A reconciliation has not been provided in
reliance on Item 10(e)(1)(i)(B) of Regulation S-K because such
