1) Mineral Reserves are contained within Measured and Indicated pit designs, and supported by a mine plan, featuring variable throughput rates, stockpiling and cut-off optimization. The pit designs and mine plan were optimized on diluted grades using the following economic and technical parameters: Metal price for gold of
US$975/oz; reference mining cost of US$1.67/t incremented US$0.0031/t/m with depth from the 220 m elevation (equates to an average mining cost of US$2.14/t), variable processing cost based on the formula 2.1874 x (S%) + 10.65 for each US$/t processed; general and administrative cost of US$2.27/t processed; stockpile
rehandle costs of US$0.19/t processed assuming that 45% of mill feed is rehandled; variable recoveries by rock type, ranging from 86.66% in shale to 94.17% in intrusive rocks in the Akivik domain; refining and freight charges of US$1.78/oz gold; royalty considerations of 4.5%; and variable pit slope angles, ranging from 23° to 43º.
Mineral Reserves are reported using an optimized net sales return value based on the following equation: Net Sales Return = Au grade * Recovery * (US$975/oz - (1.78+ (US$975/oz - 1.78) * 0.045)) (10.65 + 2.1874 * (S%) + 2.27 + 0.19) and reported in US$/tonne. Assuming an average recovery of 89.54% and an average S% grade
of 1.07%, the marginal gold cut-off grade would be approximately 0.57 g/t, or the gold grade that would equate to a 0.001 NSR cut-off at these same values. The life of mine strip ratio is 5.48. The assumed life-of-mine throughput rate is 53.5 kt/d.
2) Mineral Resources are contained within a conceptual Measured, Indicated and Inferred optimized pit shell using the following assumptions: gold price of US$1,200/oz; variable process cost based on 2.1874 * (sulphur grade) + 10.6485; administration cost of US$2.29/t; refining, freight & marketing (selling costs) of US$1.85/oz
recovered; stockpile rehandle costs of US$0.20/t processed assuming that 45% of mill feed is rehandled; variable royalty rate, based on royalty of 4.5% * (Au price - selling cost). Mineral Resources have been estimated using a constant Net Sales Return cut-off of US$0.001/t milled. The Net Sales Return was calculated using the
formula: Net Sales Return = Au grade * Recovery * (US$1,200/oz - (1.85 + ((US$1,200/oz - 1.85) * 0.045)) - (10.65 + 2.1874 * (S%) + 2.29 +0.20)) and reported in US$/tonne. Mineral Resources are inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Inferred
Resources are in addition to Measured and Indicated Resources. Inferred Resources have great uncertainty as to their existence and whether they can be mined legally or economically. See "Cautionary Note Concerning Reserve & Resource Estimates" on slide 3.

Most Recent Disclosure
"Donlin Creek Gold Project Alaska, USA, NI 43-101 Technical Report on Second Updated Feasibility Study" prepared by AMEC, effective November 18, 2011, amended January 20, 2012.
Wood (formerly AMEC Americas Limited) has updated the content with updated costs, economic assessment, permitting information and technical information relating to the permitting, generated on the Donlin Gold project since 2011. The Wood review exercise determined that the report updating exercise resulted in no material
change to the mineral resources or mineral reserves. Accordingly, NOVAGOLD will be voluntarily filing the 2021 Technical Report, entitled "NI 43-101 Technical Report on the Donlin Gold Project, Alaska, USA", with an effective date of June 1, 2021, on SEDAR in 2021 to update the scientific and technical information on the property and
to support NOVAGOLD's disclosure on the Donlin Gold project.
Clifford Krall, P.E., who is the Mine Engineering Manager for NOVAGOLD and a "qualified person" under NI 43-101, has approved the scientific and technical information contained in this presentation.
