Newmont Reports 2018 Reserves and Resources; Delivered 6.7Mozs of Reserves through exploration, Resources increase
February 21, 2019
DENVER–(BUSINESS WIRE)–Newmont Mining Corporation (NYSE: NEM) (Newmont or the Company) reported
gold Reserves of 65.4 million attributable ounces for 2018 compared to
68.5 million ounces at the end of 2017. New additions of 6.7 million
ounces exceeded the Company’s target, but were offset by negative
revisions of 3.6 million ounces and depletion of 6.1 million ounces.
Gold Resources1 increased significantly to 55.0 million
ounces in 2018 compared to 48.2 million ounces in 2017 at a constant
gold price.
The Company outperformed its exploration target, adding 6.7 million
ounces of gold Reserves by the drill bit, demonstrating the success of
Newmont’s exploration program. Revisions of 3.6 million ounces were
largely driven by model changes at Phoenix and cost and pit design
changes at Carlin. Newmont reported 5.1 million ounces of attributable
mine production in 2018 resulting in 6.1 million contained ounces of
reserve depletion.
Notable reserve additions for the year include a first-time declaration
of 2.2 million equity ounces from the Yanacocha Sulfides project, 0.8
million ounces each at Tanami and Cripple Creek & Victor (CC&V), 0.6
million ounces at Ahafo Open Pits, 0.5 million ounces at Carlin
Underground and 0.4 million equity ounces at Turquoise Ridge.
The Company’s average gold Reserve grade increased four percent to 1.19
grams per tonne compared to 1.14 grams per tonne in the prior year,
largely due to higher grade additions at Yanacocha Sulfides, Tanami, and
Carlin Underground.
Newmont’s gold Resources increased significantly to 55.0 million ounces,
up 14 percent from 48.2 million ounces in 2017 at a constant gold price,
and more than offsetting the conversion of Resource ounces to Reserves.
Positive changes to the Company’s resource base included 9.5 million
ounces added through exploration and studies and 5.3 million ounces
through the acquisition of a 50 percent interest in the Galore Creek
project. These additions were offset by the conversion of 7.7 million
ounces to Reserves, along with net negative revisions of 2.2 million
ounces primarily driven by Phoenix.
Notable resource additions include 1.8 million equity ounces at KCGM,
1.6 million ounces at Tanami, 1.0 million equity ounces at Yanacocha,
0.8 million equity ounces at Merian, 0.8 million ounces each at
Boddington and CC&V and 0.5 million ounces at Ahafo Open Pits.
Newmont’s gold Resource grade decreased to 0.76 grams per tonne compared
to 0.92 grams per tonne in the prior year, largely due to the
acquisition of Galore Creek and lower grade additions from Boddington.
The Company reported attributable Measured and Indicated2
gold resources of 39.4 million ounces, up 15 percent from the prior
year, and 15.6 million ounces of attributable Inferred gold resources,
an increase of 12 percent from the prior year.
Copper
The Company increased copper Reserves by seven percent to 1.3 million
tonnes and copper Resources3 increased significantly to 4.7
million tonnes, as compared to 2.3 million tonnes at the end of 2017.
The increase was largely driven by the Galore Creek acquisition of 2.8
million tonnes.
Exploration Outlook
Newmont’s total attributable exploration expenditure4 is
expected to increase to approximately $250 million in 2019, up nine
percent from the prior year as the Company continues to focus on growing
reserves and resources over the longer term. Around 75 percent of total
exploration spend will be dedicated to near-mine expansion programs and
the remaining 25 percent will be allocated to the advancement of
greenfield projects and innovation programs. Geographically, the Company
expects to invest approximately 35 percent in North America, 20 percent
in Australia and the remainder in South America, Africa and other
locations.
Gold Reserve Sensitivity
A $100 increase in gold price would result in an approximate seven
percent increase in gold reserves while a $100 decrease in gold price
would result in an approximate 13 percent decrease in gold reserves.
These sensitivities assume an oil price of $65 per barrel (WTI) and an
Australian dollar exchange rate of $0.75.

Reserve and Resource Tables
Proven and Probable reserves are based on extensive drilling, sampling,
mine modeling and metallurgical testing from which we determine economic
feasibility. Metal price assumptions follow SEC guidance not to exceed a
three year trailing average. The price sensitivity of reserves depends
upon several factors including grade, metallurgical recovery, operating
cost, waste-to-ore ratio and ore type. Metallurgical recovery rates vary
depending on the metallurgical properties of each deposit and the
production process used. The reserve tables included in this release
list the average metallurgical recovery rate for each deposit, which
takes into account the assumed processing methods. The cut-off grade, or
lowest grade of material considered economic to process, varies with
material type, price, metallurgical recoveries, operating costs and co-
or by-product credits. The Proven and Probable reserve figures presented
herein are estimates based on information available at the time of
calculation. No assurance can be given that the indicated levels of
recovery of gold and copper will be realized. Ounces of gold and silver
or pounds of copper included in the proven and probable reserves are
those contained prior to losses during metallurgical treatment. Reserve
estimates may require revision based on actual production. Market
fluctuations in the price of gold or copper, as well as increased
production costs or reduced metallurgical recovery rates, could render
certain proven and probable reserves containing relatively lower grades
of mineralization uneconomic to exploit and might result in a reduction
of reserves.
The Measured, Indicated, and Inferred resource figures presented herein
are estimates based on information available at the time of calculation
and are exclusive of reserves. A “Mineral Resource” is a concentration
or occurrence of solid material of economic interest in or on the
Earth’s crust in such form, grade, or quality and quantity that there
are reasonable prospects for eventual economic extraction. The location,
quantity, grade or quality, continuity and other geological
characteristics of a Mineral Resource are known, estimated or
interpreted from specific geological evidence and knowledge, including
sampling. Mineral Resources are sub-divided, in order of increasing
geological confidence, into Inferred, Indicated and Measured categories.
Ounces of gold and silver or pounds of copper included in the Measured,
Indicated and Inferred resources are those contained prior to losses
during metallurgical treatment. Market fluctuations in the price of gold
and copper, as well as increased production costs or reduced
metallurgical recovery rates, could change future estimates of
resources. Please refer to the reserves and resources cautionary
statement at the end of the release.
We publish reserves and resources annually, and will recalculate
reserves and resources at year-end 2019, taking into account metal
prices, changes, if any, in future production and capital costs, mine
designs, model changes, divestments and depletion as well as any
acquisitions and additions during 2019.
