Grey areas indicate
potential new mining areas
- Focused on optimal profitability by mining an open pit and underground mine that drives FCF and improves NPV
- A smaller, more profitable open pit focused on mining high and medium grade ore that drives a significant reduction in waste tonnes of more than 150Mt; Opportunity for further open pit and cost optimization
- Free cash flow generation beginning in Q4 2020, sustaining over the mine life
- Underground mine plan includes optimally profitable areas accessed via 5 portals; decreased capital development spend
- Opportunity to extend underground mine life in a higher gold price environment
Create a Profitable Open Pit and Underground Mine Plan at $1,275 Gold | 12 |

New Afton Mine
NI 43-101 Technical Report: Highlights
- 48 Mt of ore mined(2020-2029) at an avg. of 0.68 g/t gold and 0.77% copper
- Average annual production of 74 Mlb of copper and 90,700 oz. of gold(2020-2029) with stockpiled ore processed in 2030
- Production fromC-zone begins in Q4 2024, ramping-up to full production from 2025-2029 with average annual production of 76 Mlb of copper and 99,000 oz. of gold for the period
- Lower production expected for the2021-2024 period could be partially offset with the additional resources from the lower SLC zone through exploration drilling
- Self-fundeddevelopment of C-zone from 2020-20241
- Thickened and amended tailings will be utilized to stabilize current tailings facility and historic tailings facility ultimately depositing into historic Afton pit
- Geotechnical study updates to optimize mine plan and subsidence control
- Total capital ($175M sustaining and $460M growth) elevated from 2020 to 2023 forC-zone development; decreasing in 2024-2026 and minimal capital over the balance of the mine life
Self-funded Project Generates ~$1 billion FCF

NE Trend Target:Field reconnaissance exploration to assess the potential for shear hosted high grade gold discovery within ~15 km regional structural corridor has been completed in 2019. Two broader areas with coincident geochemical and geophysical anomalism have been defined for first pass exploration drilling in 2020.
Geological mapping, soil and rock sampling to assess the prospectivity of additional areas within the broader claims block will continue during 2020, with the objective to define drill-ready targets.
Permit application for drilling program has been submitted for a drilling campaign planned in the first half of 2020.

5.New Gold reports its Measured and Indicated Mineral Resources exclusive of Mineral Reserves. Measured and Indicated Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Inferred Mineral Resources have a greater amount of uncertainty as to their existence and technical feasibility, do not have demonstrated economic viability, and are likewise exclusive of Mineral Reserves. Numbers may not add due to rounding.

NotestoMineral Reserve and Resource Estimates (cont'd)
- Mineral Resources are classified as measured, indicated and inferred based on relative levels of confidence in their estimation and on technical and economic parameters consistent with the methods considered to be most suitable to their potential commercial extraction. The designators 'open pit' and 'underground' may be used to indicate the envisioned mining method for different portions of a resource. Similarly, the designators 'direct processing' and 'lower grade material' may be applied to differentiate material envisioned to be mined and processed directly from material to be mined and stored separately for future processing. Mineral Reserves and Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing and other risks and relevant issues. Additional details regarding Mineral Reserve and Mineral Resource estimation, classification, reporting parameters, key assumptions and associated risks for each of New Gold's material properties are provided in the respective NI43-101 Technical Reports, which will be available at www.sedar.com within 45 days of New Gold's press release dated February 13, 2020 with respect to the Rainy River and New Afton updated life of mine plans.
- The preparation of New Gold's consolidated statement and estimation of mineral reserves has been completed under the oversight and review of Mr. Andrew Croal, Director of Technical Services for the Company. Mr. Croal is a Professional Engineer and member of the Association of Professional Engineers Ontario. Preparation of New Gold's consolidated statement and estimation of mineral resources has been completed under the oversight and review of Mr. Michele Della Libera, Director, Exploration for the Company.

Endnotes
CAUTIONARY NOTE TO U.S. READERS CONCERNING ESTIMATES OF MINERAL RESERVES AND MINERAL RESOURCES
Information concerning the properties and operations of New Gold has been prepared with Canadian standards for reporting of mineral resource estimates, which differ in some respects from United States standards. In particular, and without limiting the generality of the foregoing, the terms "inferred mineral resources," "indicated mineral resources," "measured mineral resources" and "mineral resources" used or referenced in this presentation are Canadian mineral disclosure terms as defined in accordance with NI 43-101 under the guidelines set out in the 2014 Canadian Institute of Mining, Metallurgy and Petroleum Standards for Mineral Resources and Mineral Reserves, Definitions and Guidelines, May 2014 (the "CIM Standards"). Until recently, the CIM Standards differed significantly from standards in the United States. The U.S. Securities and Exchange Commission (the "SEC") has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"). These amendments became effective February 25, 2019 (the "SEC Modernization Rules") with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7, which will be rescinded from and after the required compliance date of the SEC Modernization Rules. 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 definitions under the CIM Standards, as required under NI 43-101. Accordingly, during this period leading up to the compliance date of the SEC Modernization Rules, information regarding mineral resources or mineral reserves contained or referenced in this presentation may not be comparable to similar information made public by United States companies.
Readers are cautioned that "inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies, except in limited circumstances. The term "resource" does not equate to the term "reserves". Readers should not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Readers are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable.

Non-GAAPMeasures
NON-GAAP MEASURES | |
(1) ALL-IN SUSTAINING COSTS | |
"All-in sustaining costs" per ounce is a non-GAAP financial measure. Consistent with guidance announced in 2013 by the World Gold Council, an association of various gold mining | |
companies from around the world of which New Gold is a member, New Gold defines "all-in sustaining costs" per ounce as the sum of total cash costs, capital expenditures that are | |
sustaining in nature (as presented in the cash flow statement), corporate general and administrative costs, capitalized and expensed exploration that is sustaining in nature and | |
environmental reclamation costs, all divided by the ounces of gold sold to arrive at a per ounce figure. New Gold believes this non-GAAP financial measure provides further transparency | |
into costs associated with producing gold and assists analysts, investors and other stakeholders of the Company in assessing the Company's operating performance, its ability to generate | |
free cash flow from current operations and its overall value. This data is furnished to provide additional information and is a non-GAAP financial measure. All-in sustaining costs presented | |
do not have a standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a | |
substitute for measures of performance prepared in accordance with IFRS and is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under | |
IFRS. Further details regarding historical all-in sustaining costs and a reconciliation to the nearest IFRS measures are provided in the MD&A accompanying New Gold's financial | |
statements filed from time to time on www.sedar.com. | |
(2) SUSTAINING CAPITAL | |
"Sustaining capital" is a non-GAAP financial measure as well as "sustaining lease". New Gold defines sustaining capital as net capital expenditures that are intended to maintain operation | |
of its gold producing assets. A sustaining lease is similarly a capital lease payment that is sustaining in nature. To determine sustaining capital expenditures, New Gold uses cash flow | |
related to mining interests from its statement of cash flows and deducts any expenditures that are non-sustaining or growth capital. Management uses sustaining capital and other | |
sustaining costs, to understand the aggregate net result of the drivers of all-in sustaining costs other than total cash costs. Sustaining capital and sustaining lease are intended to provide | |
additional information only, does not have any standardized meaning under IFRS, and may not be comparable to similar measures presented by other mining companies. It should not be | |
considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. | |
(3) TOTAL CASH COSTS | |
"Total cash costs" per ounce is a non-GAAP financial measure which is calculated in accordance with a standard developed by The Gold Institute, a worldwide association of suppliers of | |
gold and gold products that ceased operations in 2002. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of | |
other companies. New Gold reports total cash costs on a sales basis. The Company believes that certain investors use this information to evaluate the Company's performance and ability | |
to generate liquidity through operating cash flow to fund future capital expenditures and working capital needs. This measure, along with sales, is considered to be a key indicator of the | |
Company's ability to generate operating earnings and cash flow from its mining operations. Total cash costs include mine site operating costs such as mining, processing and | |
administration costs, royalties, production taxes, and realized gains and losses on fuel contracts, but are exclusive of amortization, reclamation, capital and exploration costs and net of by- | |
product sales. Total cash costs are then divided by ounces of gold sold to arrive at a per ounce figure. Co-product cash costs remove the impact of other metal sales that are produced as | |
a by-product of gold production and apportion the cash costs to each metal produced on a percentage of revenue basis, and subsequently divides the amount by the total ounces of gold | |
or silver or pounds of copper sold, as the case may be, to arrive at per ounce or per pound figures. Unless otherwise indicated, all total cash cost information in this presentation is net of | |
by-product sales. This data is furnished to provide additional information and is a non-GAAP financial measure. Total cash costs and co-product cash costs presented do not have a | |
standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a substitute for | |
measures of performance prepared in accordance with IFRS and is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under GAAP. Further | |
details regarding historical total cash costs and a reconciliation to the nearest IFRS measures are provided in the MD&A accompanying New Gold's financial statements filed from time to | |
time on www.sedar.com. | |
(4) FREE CASH FLOW | |
"Free cash flow" is defined as operating cash flow less sustaining capital expenditures. | |
(5) GROWTH CAPITAL | |
"Growth capital" is a non-GAAP financial measure. New Gold terms non-sustaining capital costs to be "growth capital", which are capital expenditures to develop new operations or capital | |
expenditures related to major projects at existing operations where these projects will materially increase production. To determine growth capital expenditures, New Gold uses cash flow | |
related to mining interests from its statement of cash flows and deducts any expenditures that are sustaining capital. Growth capital is intended to provide additional information only, does | 132 |
not have any standardized meaning under IFRS, and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a |
substitute for measures of performance prepared in accordance with IFRS.
