Cautionary note regarding forward-looking statements

Certain information contained in this presentation, including any information relating to New Gold's future financial or operating performance are "forward-looking". All statements in this presentation, other than statements of historical fact, which address events, results, outcomes or developments that New Gold expects to occur are "forward-looking statements". Forward-looking statements are statements that are not historical facts and are generally, but not always, identified by the use of forward-looking terminology such as "plans", "expects", "is expected", "budget", "scheduled", "targeted", "estimates", "forecasts", "intends", "anticipates", "projects", "potential", "believes" or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "should", "might" or "will be taken", "occur" or "be achieved" or the negative connotation of such terms. Forward- looking statements in this presentation include, among others, statements with respect to: the Company's expectations and guidance regarding production, costs, capital investments and expenses on a consolidated and mine-by-mine basis, and the factors and timing contributing to those expected results; the significant decrease in capital expenditures anticipated over the upcoming 5-year average period for both assets; the Company's planned priorities, anticipated next steps and mining activity focus areas for the Rainy River Mine and New Afton Mine, and the projected results therefrom; an anticipated stronger second half of the year and delivering on updated guidance; the continued review of optimization opportunities and assessment of cost reduction initiatives; the projected strengthening in production in the second half of the year at Rainy River and the expected percentage of annual production resulting therefrom; development of the Intrepid underground zone and projected timing for mining activities and initial production; planned timing for completion of the tailing dam raise; planned 2022 open pit mine plan changes at Rainy River, and the anticipated results therefrom; the ramp-up of production at B3 and expectations regarding timing for development completion and production; C-Zone development and projected timing for mining activities and first ore; advancing exploration activities at both sites and expected delivery of an exploration update; the potential for additional conversion of Mineral Resources to Mineral Reserves over time and an associated extension of mine life; anticipated timing for receipt of the C-Zone permit; projected fourth quarter access to higher grade ore material at Rainy River; anticipated short and long term benefits from advancing the underground plan at Rainy River; expected timing for completion of the North Lobe open pit mining; and the Company's projections regarding free cash flow and the factors contributing thereto.

All forward-looking statements in this presentation are based on the opinions and estimates of management that, while considered reasonable as at the date of this press release in light of management's experience and perception of current conditions and expected developments, are inherently subject to important risk factors and uncertainties, many of which are beyond New Gold's ability to

control or predict. Certain material assumptions regarding such forward-looking statements are discussed in this presentation, New Gold's latest annual MD&A, its most recent annual information form and technical reports on the Rainy River Mine and New Afton Mine filed on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. In addition to, and subject to, such assumptions discussed in more detail elsewhere, the forward-looking statements in this presentation are also subject to the following assumptions: (1) there being no significant disruptions affecting New Gold's operations other than as set out herein; (2) political and legal developments in jurisdictions where New Gold operates, or may in the future operate, being consistent with New Gold's current expectations; (3) the accuracy of New Gold's current mineral reserve and mineral resource estimates and the grade of gold, silver and copper expected to be mined and the grade of gold, copper and silver expected to be mined; (4) the exchange rate between the Canadian dollar and U.S. dollar, and to a lesser extent, the Mexican Peso, and commodity prices being approximately consistent with current levels and expectations for the purposes of 2022 guidance and otherwise; (5) prices for diesel, natural gas, fuel oil, electricity and other key supplies being approximately consistent with current levels; (6) equipment, labour and materials costs increasing on a basis consistent with New Gold's current expectations; (7) arrangements with First Nations and other Aboriginal groups in respect of the New Afton Mine and Rainy River Mine being consistent with New Gold's current expectations; (8) all required permits, licenses and authorizations being obtained from the relevant governments and other relevant stakeholders within the expected timelines and the absence of material negative comments or obstacles during any applicable regulatory processes; (9) there being no significant disruptions to the Company's workforce at either the Rainy River Mine or New Afton Mine due to cases of COVID-19 (including any required self-isolation requirements due to cross-border travel to the United States or any other country or any other reason) or otherwise; (10) the responses of the relevant governments to the COVID-19 outbreak being sufficient to contain the impact of the COVID-19 outbreak;

1. there being no material disruption to the Company's supply chains and workforce that would interfere with the Company's anticipated course of action at the Rainy River Mine and the New Afton Mine; and (12) the long-term economic effects of the COVID- 19 outbreak not having a material adverse impact on the Company's operations or liquidity position.
