Orla Mining Expands into Nevada with Acquisition of Gold Standard Ventures

VANCOUVER, June 13, 2022 - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") and Gold Standard Ventures Corp. ("Gold Standard" or "GSV") (TSX: GSV) (NYSE: GSV) are pleased to announce that they have entered into a definitive agreement (the "Arrangement Agreement") whereby Orla will acquire all of the issued and outstanding shares of Gold Standard by way of a court-approved plan of arrangement (the "Transaction").

Gold Standard's key asset is the 100%-owned South Railroad Project ("South Railroad"), a feasibility-stage, open pit, heap leach project located on the prolific Carlin trend in Nevada. In February 2022, Gold Standard completed a robust Feasibility Study and permitting activities are currently underway. Gold Standard also owns the Lewis Project ("Lewis"), a large, strategically located, prospective land package on the Battle Mountain trend in Nevada.

Jason Simpson, Chief Executive Officer of Orla Mining - "This acquisition advances our strategy of creating stakeholder value through responsibly building and operating a portfolio of high-margin, cash-generating assets with superior geological prospectivity. The South Railroad Project is analogous to our recently completed Camino Rojo mine - a low capital intensity, open pit, heap leach project in a desirable location with exploration upside. We have the team, partners, and financial resources to develop this quality asset and we are ready to go."

Under the terms of the Transaction, Gold Standard shareholders will receive, in exchange for each Gold Standard common share (a "Gold Standard Share") held, 0.1193 of a common share of Orla (each whole share, an "Orla Share") and C$0.0001 (the "Consideration"). The Consideration implies a purchase price of C$0.655 per Gold Standard Share, or gross consideration of C$242 million, and represents a 35% premium based on the close of Gold Standard's and Orla's share price on the Toronto Stock Exchange ("TSX") on June 10, 2022 and a 35% premium based on Gold Standard's 10-day volume weighted average price ("VWAP") on the TSX for the period ended June 10, 2022. Existing shareholders of Orla and Gold Standard will own approximately 87% and 13% of the pro forma company, respectively, following the close of the Transaction.


ACQUISITION HIGHLIGHTS AND STRATEGIC RATIONALE

• Continues Orla's strategy of creating value for all stakeholders by responsibly building and operating high-margin mines in stable jurisdictions with superior geology.


• South Railroad is a low-complexity, feasibility-stage project with robust project economics and is analogous to the recently completed Camino Rojo Oxide Mine.


• South Railroad combined with the Camino Rojo Oxide Mine and Orla's robust organic growth pipeline in Mexico and Panama creates a path towards annual gold production of 500,000 ounces at industry leading all-in cost margins.


• Entry into Nevada with extensive and highly prospective land positions in the Carlin and Battle Mountain trends to underpin a long-term base of operations.


• Increases Orla's proven and probable reserve base to 3.8 million gold ounces and its measured and indicated mineral resources to 12.3 million gold ounces.


• South Railroad dovetails with Orla's robust project pipeline and is expected to be developed without further equity dilution for Orla shareholders.

BENEFITS TO GOLD STANDARD SHAREHOLDERS

• Immediate upfront premium of 35%.


• Ongoing exposure to future value creating milestones at South Railroad and Lewis, as well as Orla's robust portfolio of high-quality producing and development assets.


• Participation in an established gold producer with proven construction capabilities, a strong exploration track record, and an industry leading low-cost growth profile.


• Significantly enhanced financial strength, cash flow generation, institutional investor following, trading liquidity, and opportunity for index inclusion.


• Leverages Orla's leadership and expertise in constructing and operating the Camino Rojo Oxide Mine, an open pit, heap leach operation with similar technical characteristics to the South Railroad project.


• Provides access to a strong balance sheet and robust cash flow generation to fund the construction of South Railroad and future exploration initiatives at reduced dilution, financing, development, and execution risk.

Jason Attew, Chief Executive Officer of Gold Standard - "We are excited to combine with Orla to create a leading gold producer with the potential to have multiple low-cost, low-complexity, open pit, heap leach operations in the near future. This transaction provides Gold Standard shareholders with an immediate upfront premium, exposure to a well-financed gold producer, and strong upside potential as Orla delivers and de-risks the combined asset portfolio. Based on their recent success in constructing the Camino Rojo Oxide Mine on schedule and under budget, we believe that Orla is an ideal partner to bring South Railroad into production."


ABOUT SOUTH RAILROAD AND LEWIS PROJECTS

South Railroad is a high-quality, open pit, heap leach project with robust economics. Key project highlights as outlined in the February 2022 Feasibility Study include:

Cautionary Note to U.S. Readers

This news release has been prepared in accordance with Canadian standards for the reporting of mineral resource and mineral reserve estimates, which differ from the previous and current standards of the United States securities laws. In particular, and without limiting the generality of the foregoing, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "inferred mineral resources,", "indicated mineral resources," "measured mineral resources" and "mineral resources" used or referenced herein and the documents incorporated by reference herein, as applicable, are Canadian mineral disclosure terms as defined 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 Definition Standards").

For United States reporting purposes, the United States Securities and Exchange Commission (the "SEC") has adopted amendments to its disclosure rules (the "SEC Modernization Rules") to modernize the mining property disclosure requirements for issuers whose securities are registered with the SEC under the Exchange Act, which became effective February 25, 2019. The SEC Modernization Rules more closely align the SEC's disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101, and replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7. Issuers were required to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards. Accordingly, mineral reserve and mineral resource information contained or incorporated by reference herein may not be comparable to similar information disclosed by United States companies subject to the United States federal securities laws and the rules and regulations thereunder.

As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding CIM Definition Standards that are required under NI 43-101. While the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that all or any part of the mineralization in these categories will be converted into a higher category of mineral resources or into mineral reserves without further work and analysis. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that all or any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable without further work and analysis. Further, "inferred mineral resources" have a greater amount of uncertainty and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred mineral resources will be upgraded to a higher category without further work and analysis. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are "substantially similar" to CIM Definitions, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules or under the prior standards of SEC Industry Guide 7.
