SSR MINING ACQUIRES 8,900 HECTARES CONTIGUOUS TO MARIGOLD MINE

VANCOUVER, B.C. – SSR Mining Inc. (NASDAQ: SSRM) (TSX: SSRM) ( “SSR Mining ”) is

pleased to announce it has acquired approximately 8,900 hectares contiguous to the Marigold

mine in Nevada, U.S . comprised of a 100% interest in the Trenton Canyon and Buffalo Valley

properties (the “Properties”) from Newmont Goldcorp Corporation (NYSE: NEM) (TSX: NGT)

(“Newmont”) and Fairmile Gold Mining, Inc (“Fairmile”) for an aggregate purchase price of $22

million in cash and the grant to Newmont of a 0.5% net smelter returns (“NSR”) royalty on each

of the Properties, and the assumption of the long-term environmental and reclamation obligations

for the Properties.

Transaction and Property Highlights

 Acquisition of a large, wholly-owned prospective land package with 340,000 ounces of

historical gold production, contiguous to the southern boundary of the Marigold mine.

 Historical Indicated Mineral Resources estimate of 418,000 ounces of gold at Buffalo Valley.

 Increases Marigold’s land position on trend with the Mackay pit to 19,800 hectares in Nevada’s

Battle Mountain - Eureka gold belt, an 84% increase.

 Planned exploration activities aim to further define and potentially increase Mineral Resources

at the Properties.

 With exploration success, potential exists to enhance the current Marigold mine plan to extend

mine life, increase production or improve margins.

 Increases land position, which is favorable to host oxide and additional deep sulphide

exploration targets.

 Also in 2018 and 2019, c onsolidated four additional parcels totaling 130 hectares of land

located within the Marigold mine land package.

Paul Benson, President and CEO said, “Acquiring the Trenton Canyon and Buffalo Valley

properties is expected to increase our gold resources and add multiple zones of mineralization

proximate to our Marigold mine infrastructure. The acquisitions increase our land position by 84%

since acquiring the Marigold mine and the Valmy property. Exploration plans aim to upgrade and

expand known gold mineralization to potentially extend mine life, increase operating flexibility or

access higher margin tonnes. We expect to commence exploration activities in the near-term and

to begin incorporating the Properties into our longer-term mine planning as we evaluate

opportunities to continue creating value at Marigold for our shareholders.”

Overview of the Properties

The Properties comprise an 8,900-hectare land package to the south and contiguous with the

Marigold mine. The addition of the Properties increases our total land holding at the Marigold

mine to 19,800 hectares.

The Trenton Canyon property consists of 7,350 hectares located immediately south and along

the mineralized trend from the Marigold mine. The property was previously operated as an open-

pit run-of-mine heap leach operation from 1996 to 2001. Based on data provided by Newmont,

production during this period totaled approximately 290,000 ounces of gold from the North Peak,

West and South pits within the Trenton Canyon property. The property also includes the North

Peak heap leach pads and processing facilities. The Trenton Canyon property was previously

100% owned by Newmont.

The Buffalo Valley property consists of 1,550 hectares located southwest of the Marigold mine.

The historic Indicated Mineral Resources estimate for Buffalo Valley is 418,000 ounces of gold

(20 million tonnes at an average gold grade of 0.65 g/t), as of December 31, 20181. Such Mineral

Resources estimate was prepared by Newmont and reported in its press release dated February

21, 2019, and is based on Newmont data (including collar, survey, lithology and assay data),

using ordinary kriging with appropriate estimation parameters in accord ance with industry

standards. Such estimate needs to be verified by SSR Mining by conducting detailed verification

checks, including QA/QC of location, geological, density and assay data. A qualified person for

SSR Mining has not done sufficient work to classify the his torical estimate at Buffalo Valley as

current Mineral Resources and therefore SSR Mining is not treating the historical estimate as

current Mineral Resources. Based on data provided by Newmont, historical production at Buffalo

Valley from 1989 to 1991 tota led approximately 50,000 ounces of gold. Buffalo Valley was

previously operated as a joint venture between Newmont (70% ownership and operator) and

Fairmile (30% ownership).

Historical exploration activities on the Properties consist of over 2,700 drill holes totaling more

than 340,000 meters of drilling completed between 1980 and 2012. The Properties host the same

rock formations present at the Marigold mine, while displaying a higher intensity of rock alteration.

Historic drilling indicates the prospective mineralized corridor at Trenton Canyon extends for at

least 3,000 meters in a north -south direction, while surface geochemical anomalies potentially

extend the mineralized footprint for over 5,000 meters. Our exploration activities are expected to

commence in the near-term and will initially target Mineral Resources definition and confirmation.

See Figure 1 for a map of the Properties and the current Marigold mine. This figure also shows

four additional land parcels acquired in 2018 and 2019, which have the potential for additional

mineralization or infrastructure benefits.

Transaction Overview

Under the terms of the purchase agreements entered into with Newmont and Fairmile, we have

acquired Newmont’s and Fairmile ’s respective interest in the Propert ies for aggregate cash

consideration of $ 22 million plus the grant to Newmont of a 0.5% NSR royalty on all mineral

production from each of the Properties. The purchase price was funded from cash on hand. Under

1 Mineral Resources disclosed by Newmont have been grossed up to illustrate 100% SSR Mining ownership

of Buffalo Valley and are subject to rounding. Metal price used for Mineral Resources estimate is $1,400

per ounce of gold. Mineral Resources that are not Mineral Reserves do not have demonstrated economic

viability.

the terms of the purchase a greements, we have provided financial assurances to the

environmental regulatory authorities with respect to the Properties’ long-term environmental and

reclamation obligations totaling approximately $23.1 million.

Cautionary Note to U.S. Investors

This news release includes Mineral Reserves and Mineral Resources classification terms that comply with

reporting standards in Canada and the Mineral Reserves and the Mineral Resources estimates are made

in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that

establishes standards for all public disclosure an issuer makes of scientific and technical information

concerning mineral projects. These standards differ significantly from the requirements of the SEC set out

in SEC Industry Guide 7. Consequently, Mineral Reserves and Mineral Resources information included in

this news release is not comparable to similar information that would generally be disclosed by domestic

U.S. reporting companies subject to the reporting and disclosure requirements of the SEC. Under SEC

standards, mineralization may not be classified as a “reserve” unless the determination has been made that

the mineralization could be economically produced or extracted at the time the reserve determination is

made. In addition, the SEC’s disclosure standards normally do not permit the inclusion of information

concerning “Measured Mineral Resources,” “Indicated Mineral Resources” or “Inferred Mineral Resources”

or other descriptions of the amount of mineralization in mineral deposits that do not constitute “reserves”

by U.S. standards in documents filed with the SEC. U.S. investors should understand that “Inferred Mineral

Resources” have a great amount of uncertainty as to their existence and great uncertainty as to their

economic and legal feasibility. Moreover, the requirements of NI 43-101 for identification of “reserves” are

also not the same as those of the SEC, and reserves reported by us in compliance with NI 43-101 may not

qualify as “reserves” under SEC standards. Accordingly, information concerning mineral deposits set forth

herein may not be comparable with information made public by companies that report in accordance with

U.S. standards.
