Forward Looking Information and other Cautionary Factors

This release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than

statements of historical facts, that address exploration drilling, exploitation activities and events or developments that the Company

expects are forward-looking statements. These statements include statements regarding (i) the mine plan for the Pebble Project, (ii)

the social integration of the Pebble Project into the Bristol Bay region and benefits for Alaska, (iii) the political and public support for

the permitting process, (iv) the issuance of a positive Record of Decision by the US Army Corps of Engineers and the ability of the

Pebble Project to secure state permits, (v) the right -sizing and de -risking of the Pebble Proj ect, (vi) the design and operating

parameters for the Pebble Project mine plan, (vii) exploration potential of the Pebble Project, (viii) future demand for copp er and

gold, (ix) the potential partnering of the Pebble Project, and (x) the ability and timeta ble of NDM to develop the Pebble Project and

become a leading copper, gold and molybdenum producer. Although NDM believes the expectations expressed in these forward -

looking statements are based on reasonable assumptions, such statements should not be in any way be construed as guarantees that

the Pebble Project will secure all required government permits, establish the commercial feasibility of the Pebble Project or develop

the Pebble Project. Assumptions used by NDM to develop forward -looking statements include the assumptions that (i) the Pebble

Project will obtain all required environmental and other permits and all land use and other licenses without undue delay, (ii) studies

for the development of the Pebble Project will be positive, (iii) NDM’s estima tes of mineral resources will not change, (iv) NDM will

be able to establish the commercial feasibility of the Pebble Project, and (v) NDM will be able to secure the financing requi red to

develop the Pebble Project. The likelihood of future mining at the Pebble Project is subject to a large number of risks and will require

achievement of a number of technical, economic and legal objectives, including (i) obtaining necessary mining and constructio n

permits, licenses and approvals without undue delay, including without delay due to third party opposition or changes in government

policies, (ii) finalization of the mine plan for the Pebble Project, (iii) the completion of feasibility studies demonstratin g that any

Pebble Project mineral resources that can be eco nomically mined, (iv) completion of all necessary engineering for mining and

processing facilities, (v) the inability of NDM to secure a partner for the development of the Pebble Project, and (vi) receipt by NDM

of significant additional financing to fund these objectives as well as funding mine construction, which financing may not be available

to NDM on acceptable terms or on any terms at all. NDM is also subject to the specific risks inherent in the mining business as well

as general economic and business conditions, such as the current uncertainties with regard to COVID-19.

The National Environment Policy Act Environmental Impact Statement process requires a comprehensive “alternatives assessment”

be undertaken to consider a broad range of development a lternatives, the final project design and operating parameters for the

Pebble Project and associated infrastructure may vary significantly from that contemplated in this presentation. As a result, the

Company will continue to consider various development options and no final project design has been selected at this time.
