ORLA MINING EXPANDS INTO NEVADA WITH ACQUISITION OF GOLD STANDARD VENTURES

Orla Mining Ltd. and Gold Standard Ventures Corp. have entered into a definitive agreement, whereby Orla will acquire all of the issued and outstanding shares of Gold Standard by way of a court-approved plan of arrangement.

Gold Standard's key asset is the 100-per-cent-owned South Railroad project, 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 under way. Gold Standard also owns the Lewis project, a large, strategically located, prospective land package on the Battle Mountain trend in Nevada.

Jason Simpson, chief executive officer of Orla Mining, stated: "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 held, 0.1193 of a common share of Orla and 0.01 cent. The consideration implies a purchase price of 65.5 cents per Gold Standard share, or gross consideration of $242-million, and represents a 35-per-cent premium based on the close of Gold Standard's and Orla's share prices on the Toronto Stock Exchange on June 10, 2022, and a 35-per-cent premium based on Gold Standard's 10-day volume-weighted average price (VWAP) on the Toronto Stock Exchange for the period ended June 10, 2022. Existing shareholders of Orla and Gold Standard will own approximately 87 per cent and 13 per cent 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 toward 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 per cent;
• Continuing 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 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 finance 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, stated: "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 derisks 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:

• Average annual gold production of 152,000 ounces over the first four years and 124,000 ounces over the mine life;
• Life-of-mine average all-in sustaining cash cost of approximately $1,020 (U.S.) per gold ounce;
• Total gold production of one million ounces over an eight-year mine life;
• Initial capital of $190-million (U.S.);
• Average annual free cash flow of $98-million (U.S.) over the first four years;
• $315-million (U.S.) after-tax net present value at a 5-per-cent discount rate;
• 44-per-cent after-tax internal rate of return;
• Proven and probable reserve estimate of 1.6 million gold ounces at 0.77 gram per tonne;
• Measured and indicated resource estimate of 1.8 million gold ounces at 0.74 gram per tonne.

Permitting of South Railroad is currently progressing toward a record of decision from the U.S. Bureau of Land Management.

South Railroad is situated within a prospective 21,000-hectare land package that provides future opportunities for resource expansion and conversion and the discovery of new deposits. Key oxide and sulphide exploration targets include Pinion SB, Jasperoid Wash, Dixie, LT, POD/Sweet Hollow and North Bullion.

The Lewis project is strategically located adjacent to the north and within the plan of operations boundary of Nevada Gold Mines' Phoenix operation. The Lewis project has an inferred mineral resource of 206,000 ounces of gold at 0.83 gram per tonne and several additional prospective targets that have the potential to expand the resource base.
