**EXPLANATORY
  NOTE**

Explanation
  of amendment on Northern Dynasty Minerals Ltd. Annual Report on Form 40-F/A
  for the fiscal year ended December 31, 2007:

The original
  Annual Report on Form 40-F filed on EDGAR on March 31, 2008 did not contain
  a consent form and certain information in the Report of Independent Public Accounting
  Firm. This information has been included in this amendment on Form 40-F/A. All
  other financial and other information contained in the originally filed Annual
  Report on Form 40-F remains unchanged.

INTRODUCTORY INFORMATION

In this annual report, references to we, our, us, the
Company or Northern Dynasty, mean Northern Dynasty Minerals Ltd. its
subsidiaries and consolidated interests, unless the context suggests
otherwise.

Unless otherwise indicated, all amounts in this annual report
are in Canadian dollars and all references to $ mean Canadian dollars.

PRINCIPAL DOCUMENTS

The following documents that are filed as exhibits to this
annual report are incorporated by reference herein:

- our Annual Information Form for the year ended December 31, 2007;
- our Audited Consolidated Financial Statements as at and for the three years
  ended December 31, 2007, 2006 and 2005; and
- our Management Discussion and Analysis for the year ended December 31,
  2007.

FORWARD-LOOKING STATEMENTS

This annual report includes or incorporates by reference
certain statements that constitute forward-looking statements within the
meaning of the United States Private Securities Litigation Reform Act of
1995. These statements appear in a number of places in this annual report
and documents incorporated by reference herein and include statements regarding
our intent, belief or current expectation and that of our officers and
directors. These forward-looking statements involve known and unknown risks and
uncertainties that may cause our actual results, performance or achievements to
be materially different from any future results, performance or achievements
expressed or implied by such forward-looking statements. When used in this
annual report or in documents incorporated by reference in this annual report,
words such as believe, anticipate, estimate, project, intend,
expect, may, will, plan, should, would, contemplate, possible,
attempts, seeks and similar expressions are intended to identify these
forward-looking statements. These forward-looking statements are based on
various factors and were derived utilizing numerous assumptions that could cause
our actual results to differ materially from those in the forward-looking
statements. Accordingly, you are cautioned not to put undue reliance on these
forward-looking statements. Forward-looking statements include, among others,
statements regarding:

- our expected financial performance in future periods;
- our plan of operations, including our plans to carry out exploration and
  development activities;
- our ability to raise capital for exploration and development activities;
- our expectations regarding the exploration and development potential of our
  properties; and
- factors relating to our investment decisions.

Certain of the assumptions we have made include assumptions
regarding, among other things:

- the cost of carrying out exploration and development activities on our
  mineral properties;

---

- our ability to obtain the necessary expertise in order to carry out our
  exploration and development activities within the planned time periods; and
- our ability to obtain adequate financing on acceptable terms.

Some of the risks and uncertainties that could cause our actual
results to differ materially from those expressed in our forward-looking
statements include:

- the speculative nature of the mineral resource exploration business;
- the exploration stage of our mineral projects;
- the lack of known reserves on our mineral properties;
- our inability to establish that our Pebble Property contains commercially
  viable deposits of ore;
- our ability to recover the financial statement carrying values of our
  mineral property interests if the Company ceases to continue on a going
  concern basis;
- loss of the services of any of our executive officers;
- our history of financial losses;
- our ability to continue on a going concern basis;
- the volatility of gold, copper and molybdenum prices;
- the inherent risk involved in the exploration, development and production
  of minerals;
- changes in, or the introduction of new, government regulations relating to
  mining, including laws and regulations relating to the protection of the
  environment;
- the presence of unknown environmental hazards on our mineral properties;
- potential claims by third parties to the Companys mineral projects;
- our inability to insure our operations against all risks;
- the highly competitive nature of our business;
- the historical volatility in our share price;
- potential conflicts of interest relating to our directors and officers;
- the potential dilution to our shareholders from any future equity
  financings;
- the loss of services of our independent contractors; and
- the potential dilution to our shareholders from the exercise of options to
  purchase our shares.

We refer you to the section entitled Risk Factors in our
Annual Information Form. We assume no obligation to update or to publicly
announce the results of any change to any of the forward-looking statements
contained or incorporated by reference herein to reflect actual results, future
events or developments, changes in assumptions or changes in other factors
affecting the forward-looking statements.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING
ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES

The documents that have been incorporated by reference into
this annual report use the terms measured resources, indicated resources and
inferred resources. These resource estimates have been prepared in accordance
with Canadian National Instrument 43-101 Standards of Disclosure for Mineral
Projects and the Canadian Institute of Mining and Metallurgy Classification
System. These standards differ significantly from the requirement of the United
States Securities and Exchange Commission (the SEC). Investors are advised
that while the terms measured resources, indicated resources and inferred
resources are recognized and required by Canadian regulations, including
Canadian National Instrument 43-101, the SEC does not recognize them. Under
United States standards, mineralization may not be classified as a reserve
unless the determination has been made that the mineralization could be
economically and legally produced or extracted at the time the reserve
determination is made and all permits are in hand or are expected to be issued
in the near future. Investors are cautioned not to assume that any part or
all of the mineral deposits in these categories will ever be converted into
reserves.These terms 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 measured mineral resources, indicated
mineral resources, or inferred mineral resources will ever be upgraded to a
higher category. Investors are cautioned not to assume that any part of the
reported measured mineral resources, indicated mineral resources, or inferred
mineral resources in this annual report is economically or legally mineable.
Further, inferred resources have a great amount of uncertainty as to their
existence and as to whether they can be mined legally or economically.
Therefore, investors are also cautioned not to assume that all or any part of
the inferred resources exist. In accordance with Canadian rules, estimates of
inferred mineral resources cannot form the basis of feasibility or other
economic studies.

Disclosure of contained ounces in mineral resources is
permitted disclosure under Canadian regulations; however, the SEC only permits
issuers to report mineralization that does not qualify as reserves as in place
tonnage and grade without reference to unit measures.

NI 43-101 is a rule developed by the Canadian Securities
Administrators that establishes standards for all public disclosure an issuer
makes of scientific and technical information concerning mineral projects.
Unless otherwise indicated, all reserve and resource estimates contained in or
incorporated by reference in this annual report have been prepared in accordance
with NI 43-101. These standards differ significantly from the requirements of
the SEC, and reserve and resource information contained herein and incorporated
by reference herein may not be comparable to similar information disclosed by
U.S. domestic issuers.

NOTE TO UNITED STATES READERS REGARDING DIFFERENCES
BETWEEN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Company is permitted to prepare this annual report in
accordance with Canadian disclosure requirements, which are different from those
of the United States. The Company prepares its consolidated financial statements
in accordance with Canadian generally accepted accounting principles (Canadian
GAAP) which principles differ in certain respects from those applicable in the
United States (US GAAP) and from practices prescribed by the SEC. Note 11 to
our audited consolidated financial statements included herein provides a
reconciliation of the significant differences between Canadian and United States
generally accepted accounting principles.

DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, our
management carried out an evaluation, with the participation of our Chief
Executive Officer and Chief Financial Officer, of the effectiveness of our
disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e)
under the Securities Exchange Act of 1934 (the Exchange Act)). Based
upon that evaluation, our Chief Executive Officer and Chief Financial Officer
concluded that, as of the end of the period covered by this report, our
disclosure controls and procedures were effective in recording, processing,
summarizing and reporting, on a timely basis, information required to be
disclosed by us in reports that we file or submit under the Exchange Act.

It should be noted that while our Chief Executive Officer and
our Chief Financial Officer believe that our disclosure controls and procedures
provide a reasonable level of assurance that they are effective, they do not
expect that our disclosure controls and procedures or internal control over
financial reporting will prevent all errors and fraud. A control system, no
matter how well conceived or operated, can provide only reasonable, not
absolute, assurance that the objectives of the control system will be met.

There were no changes in our disclosure controls and procedures
during the fiscal year ended December 31, 2007 that materially affected, or are
reasonably likely to materially affect, our internal control over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act).

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL
REPORTING

The management of the Company is responsible for establishing
and maintaining adequate internal controls over financial reporting. The
Companys internal control system was designed to provide reasonable assurance
to the Companys management and the board of directors regarding the preparation
and fair presentation of published financial statements. Internal control over
financial reporting includes those policies and procedures that: (1) pertain to
the maintenance of records that in reasonable detail accurately and fairly
reflect the transactions and dispositions of the assets of the Company, (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with Canadian GAAP,
with a reconciliation to United States GAAP, and that receipts and expenditures
of the Company are being made only in accordance with authorizations of
management and directors of the Company, and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use or
disposition of the Companys assets that could have a material effect on the
financial statements. All internal control systems, no matter how well designed,
have inherent limitations. Therefore, even those systems determined effective
can provide only reasonable assurance with respect to financial statement
preparation and presentation.

The Companys management, with the participation of the Chief
Executive Officer and the Chief Financial Officer, has evaluated the
effectiveness of internal control over financial reporting based on the
framework and criteria established in Internal Control  Integrated Framework,
issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on this evaluation, our management has concluded that internal control
over financial reporting was effective as of December 31, 2007 to provide
reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements in accordance with Canadian GAAP, and the
reconciliation to United States GAAP.

AUDIT COMMITTEE

Our Board of Directors has established a separately-designated
independent Audit Committee of the board in accordance with Section 3(a)(58)(A)

reporting processes and the audits of our annual financial statements. As at the
date of this annual report, the Audit Committee was comprised of David Elliott,
Wayne Kirk and Gordon Fretwell.

AUDIT COMMITTEE FINANCIAL EXPERT

Our Board of Directors has determined that David Elliott, a
member of the Audit Committee of our board, is an audit committee financial
expert (as that term is defined in Item 401 of Regulation S-K under the Exchange
Act) and is an independent director under applicable laws and regulations and
the requirements of the American Stock Exchange.

of interim consolidated financial statements and attestation services that are
provided in connection with statutory and regulatory filings or engagements.

Audit-related fees are fees for assurance and related services
that are reasonably related to the performance of the audit or review of our

All Other Fees

All other fees relate to services other than the audit fees,

---

Audit Committee Pre-Approval Policies

From time to time, our management requests approval from the
Audit Committee of our board for audit and non-audit services from our
independent auditors. The Audit Committee pre-approves all such non-audit
services with set maximum dollar limits. In considering these requests with
respect to non-audit services, the Audit Committee assesses, among other things,
whether the services requested would be considered prohibited services as
contemplated by the rules of the Securities and Exchange Commission, and whether
the services requested and related fees could impair the independence of our
auditors.

OFF-BALANCE SHEET ARRANGEMENTS

We have not entered into any off-balance sheet arrangements
that have or are reasonably likely to have a current or future effect on our
financial condition, changes in financial condition, revenues, expenses, results
of operations, liquidity, capital expenditures or capital resources that is
material to investors.

CONTRACTUAL OBLIGATIONS

Other than already disclosed in the financial statements, we
did not have any contractual obligations as at December 31, 2007.

CODE OF ETHICS

We have adopted a Code of Ethics that applies to our officers,
employees and directors and promotes, among other things, honest and ethical
conduct. The code also promotes compliance by our Chief Executive Officer, Chief
Financial Officer and other senior finance staff with the Sarbanes-Oxley Act of
2002. Investors may view our Code of Ethics on our web site at www.northerndynastyminerals.com.

AMEX CORPORATE GOVERNANCE

The Companys common shares are listed for trading on The
American Stock Exchange (AMEX). Section 110 of the AMEX company guide permits
AMEX to consider the laws, customs and practices of their home country in
relaxing certain AMEX listing criteria otherwise applicable to foreign issuers,
and grants exemptions from AMEX listing criteria based on these considerations.
A company seeking relief under these provisions is required to provide written
certification from independent local counsel that the non-complying practice is
not prohibited by home country law. A description of the significant ways in
which the Companys governance practices differ from those followed by United
States domestic companies pursuant to AMEX standards is contained on the
Companys website at www.northerndynastyminerals.com. Upon listing, the
Company received an exemption from its quorum requirement. Under the AMEX
listing standards, the quorum requirement is a minimum of one third of
shareholders entitled to vote for U.S. domestic companies. The Company does not
meet this requirement and has been granted relief from this listing
standard.

UNDERTAKING

  telephone, representatives to respond to inquiries made by the Commission staff,
  and to furnish promptly, when requested to do so by the Commission staff, information
  relating to: the securities registered pursuant to Form
