New Gold Files Updated Technical Report For The Rainy River Mine

Rainy River Mine Life Extended to 2031

(All amounts are in U.S. dollars unless otherwise indicated)

TORONTO, March 31, 2022 /PRNewswire/ - New Gold Inc. ("New Gold" or the "Company") (TSX: NGD) (NYSE American: NGD) reports the filing of a Technical Report for the Company's Rainy River Mine (the "Technical Report"). The Technical Report was prepared in compliance with National Instrument 43-101 ("NI 43-101") and has an effective date of March 28, 2022. The Technical Report is available on SEDAR at www.sedar.com and on the Company's website at www.newgold.com.

The primary objective of the Technical Report is to provide an update on the open pit and expanded underground mine plans. The life of mine ("LOM") has extended to 2031 with the conversion of an additional 569,000 gold ounces in the underground main zones to Mineral Reserves. The remaining open pit will be mined using an optimized selective mining approach which, combined with stockpile movement, leads to both a smoother and sustainable mill grade and gold production profile, before transitioning to a cost-effective batch processing underground operation. The updated Technical Report was prepared using the Mineral Reserves and Mineral Resources as at December 31, 2021 and assuming metal prices of $1,400 per gold ounce and $19.00 per silver ounce, and a foreign exchange rate of $1.25 Canadian dollars to $1.00 US dollar.

"The filing of the updated Rainy River Mine Technical Report is another positive milestone towards delivering sustainable production", stated Renaud Adams, President & CEO. "I am confident that our updated approach for mining the remaining open pit should lead to a smoother, more consistent grade and production profile. The successful efforts to convert underground Mineral Resources to Mineral Reserves in 2021, which added meaningful gold ounces to the life of mine plan, has also extended the mine life to 2031 with low upfront underground development capital. Further, all-in sustaining costs continue to remain attractive and decrease significantly after 2023, providing for strong margins and free cash flow over the next decade."

• Open pit mining has historically focused on segregating higher grade ore and medium grade ore ("direct processing ore") from lower grade ore ("LGO"), which has allowed for higher grade ore being milled and the LGO material being stockpiled for future processing. In 2021, this approach was particularly challenging with reconciliation issues and with the ability to selectively mine and recover material from certain peripheral ore zones within the open pit. As the open pit continues to deepen, mining areas become narrower and the selective mining approach becomes more difficult and less efficient, resulting in an impact on productivity, costs increases, and potentially an inability to recover all ore material. In order to minimize the challenges from the segregation approach, the updated mine plan was prepared using the following approach:
• For the open pit mine plan, the direct processing ore cut-off grade has been lowered providing for an optimized selective mining approach when direct feed ore material will continue to be mined separately from the LGO.
• Direct processing ore and LGO to be mined together when efficient selective mining is no longer possible.
• The updated approach, along with processing of the stockpile ore material, produces a balanced average mill grade to support a smoother and sustainable gold eq. production profile. Annual gold eq. production is expected to average approximately 310,000 ounces per year during the 2022 to 2027 period.
• The updated mine plan predominately focuses on the remaining ounces from the main ODM zone, which has historically reconciled well with the resource model, from the second half of 2022 to 2025. The previously reported correction factor has been applied on the ODM East Lobe zone, which is expected to be completed in 2023.
• Production from the Intrepid underground zone has been accelerated compared to the 2020 technical report. Development of the main ramp and the first ore panel continues to advance on plan with initial production commencing in 2022.
• The underground main zones have been incorporated via two in-pit portals (previously four), as well as the Intrepid underground zone portal located to the east of the open pit. The development of the first in-pit portal is expected to be initiated in the first quarter of 2023 with the second portal planned to be initiated in the first quarter of 2026. The underground production profile has extended to 2031 with the conversion of Mineral Resources to Mineral Reserves in the underground main zones and their inclusion into the mine plan.
• Mill throughput is planned to average approximately 27,000 tonnes per day during the 2022 to 2027 period, with LGO stockpile supplementing underground mill feed from 2026 to 2028.
• Beginning in 2029, a cost-effective batch processing approach is expected to be implemented to mill the underground material.
• The updated Technical Report utilized an average gold recovery factor in line with the 2020 technical report of 89%.
• The Company continues to look for and identify opportunities to further optimize the mine plan and resource model. Underground stope design optimization will be undertaken with the support of data collected through delineation drilling already planned and budgeted within the updated Technical Report.

• LOM sustaining capital² is estimated to be $647 million, primarily consisting of:
• $193 million is related to open pit stripping and mobile maintenance. Approximately 90% of these costs occur in 2022 and 2023 with sustaining capital significantly decreasing beginning in 2024.
• $110 million is related to tailings construction, which is planned to be completed in 2025.
• $326 million is related to underground mining, primarily for underground ramp development, ventilation and pumping requirements.
• LOM growth capital² is estimated to be $71 million, primarily related to complete pre-production development of the underground Intrepid and main zones from 2022 to 2024.
• LOM operating expense and all-in sustaining costs² are expected to be $749 and $1,047 per gold eq. ounce, respectively. All-in sustaining costs² are expected to significantly decrease beginning in 2024, consistent with the sustaining capital profile.

Total Cash Costs per Gold eq. Ounce

"Total cash costs per gold equivalent ounce" is a non-GAAP financial performance measure that is a common financial performance measure in the gold mining industry but does not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. New Gold reports total cash costs on a sales basis and not on a production basis. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, this measure, along with sales, is a key indicator of the Company's ability to generate operating earnings and cash flow from its mining operations. This measure allows investors to better evaluate corporate performance and the Company's ability to generate liquidity through operating cash flow to fund future capital exploration and working capital needs.

This measure is intended to provide additional information only and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. This measure is not necessarily indicative of cash generated from operations under IFRS or operating costs presented under IFRS.

Total cash cost figures are 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. Total cash costs include mine site operating costs such as mining, processing and administration costs, royalties, and production taxes, but are exclusive of amortization, reclamation, capital and exploration costs. Total cash costs are then divided by gold equivalent ounces sold to arrive at the total cash costs per equivalent ounce sold.

In addition to gold, the Company produces copper and silver. Gold equivalent ounces of copper and silver produced or sold in a quarter are computed using a consistent ratio of copper and silver prices to the gold price and multiplying this ratio by the pounds of copper and silver ounces produced or sold during that quarter.

Notwithstanding the impact of copper and silver sales, as the Company is focused on gold production, New Gold aims to assess the economic results of its operations in relation to gold, which is the primary driver of New Gold's business. New Gold believes this metric is of interest to its investors, who invest in the Company primarily as a gold mining business. To determine the relevant costs associated with gold equivalent ounces, New Gold believes it is appropriate to reflect all operating costs incurred in its operations.

All-In Sustaining Costs per Gold eq. Ounce

"All-in sustaining costs per gold equivalent ounce" is a non-GAAP financial performance measure that does not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. New Gold calculates "all-in sustaining costs per gold equivalent ounce" based on guidance announced by the World Gold Council ("WGC") in September 2013. The WGC is a non-profit association of the world's leading gold mining companies established in 1987 to promote the use of gold to industry, consumers and investors. The WGC is not a regulatory body and does not have the authority to develop accounting standards or disclosure requirements.  The WGC has worked with its member companies to develop a measure that expands on IFRS measures to provide visibility into the economics of a gold mining company. Current IFRS measures used in the gold industry, such as operating expenses, do not capture all of the expenditures incurred to discover, develop and sustain gold production. New Gold believes that "all-in sustaining costs per gold equivalent ounce" provides further transparency into costs associated with producing gold and will assist analysts, investors, and other stakeholders of the Company in assessing its operating performance, its ability to generate free cash flow from current operations and its overall value.

"All-in sustaining costs per gold equivalent ounce" is intended to provide additional information only and 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. The measure is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under IFRS.

New Gold defines "all-in sustaining costs per gold equivalent ounce" as the sum of total cash costs, net capital expenditures that are sustaining in nature, corporate general and administrative costs, capitalized and expensed exploration that is sustaining in nature, lease payments that are sustaining in nature, and environmental reclamation costs, all divided by the total gold equivalent ounces sold to arrive at a per ounce figure. The definition of sustaining versus non-sustaining is similarly applied to capitalized and expensed exploration costs and lease payments. Exploration costs and lease payments to develop new operations or that relate to major projects at existing operations where these projects are expected to materially increase production are classified as non-sustaining and are excluded. Gold equivalent ounces of copper and silver produced or sold in a quarter are computed using a consistent ratio of copper and silver prices to the gold price and multiplying this ratio by the pounds of copper and silver ounces produced or sold during that quarter.

Costs excluded from all-in sustaining costs are non-sustaining capital expenditures, non-sustaining lease payments and exploration costs, financing costs, tax expense, and transaction costs associated with mergers, acquisitions and divestitures, and any items that are deducted for the purposes of adjusted earnings.

Sustaining Capital and Sustaining Leases

"Sustaining capital" and "sustaining lease" are non-GAAP financial performance measures that do not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. New Gold defines "sustaining capital" as net capital expenditures that are intended to maintain operation of its gold producing assets. Similarly, a "sustaining lease" is a 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 capital expenditures to develop new operations or capital expenditures related to major projects at existing operations where these projects will materially increase production. Management uses "sustaining capital" and "sustaining lease", to understand the aggregate net result of the drivers of all-in sustaining costs other than total cash costs. These measures are intended to provide additional information only and should not be considered in isolation or as substitutes for measures of performance prepared in accordance with IFRS.  

Growth Capital 

"Growth capital" is a non-GAAP financial performance measure that does not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. New Gold considers 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 capital expenditures that are intended to maintain operation of its gold producing assets. Management uses "growth capital" to understand the cost to develop new operations or related to major projects at existing operations where these projects will materially increase production. This measure is intended to provide additional information only and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
