Audit Committee Mandate

PURPOSE AND AUTHORITY

The audit committee is established by and among the Nevsun Resources Ltd. board of directors for the primary purpose of assisting the board in

  • overseeing the integrity of the company's financial statements;
  • overseeing the company's compliance with legal and regulatory requirements;
  • overseeing the independent auditor's qualifications and independence;
  • overseeing the performance of the company's independent auditor and internal audit function; and
  • overseeing the company's systems of disclosure controls and procedures, internal controls over financial reporting, and compliance with ethical standards adopted by the company.

The audit committee should encourage continuous improvement, and should foster adherence to the company's policies, procedures, and practices at all levels.  The audit committee should also provide for open communication among the independent auditor, financial and senior management, the internal audit function and the board of directors.

The audit committee has the authority to conduct investigations into any matters within its scope of responsibility and obtain advice and assistance from outside legal, accounting or other advisers, as necessary to perform its duties and responsibilities.

In carrying out its duties and responsibilities, the audit committee also has the authority to meet with and seek any information it requires from employees, officers, directors or external parties.

The company will provide appropriate funding, as determined by the audit committee, for compensation to the independent auditor, to any advisers that the audit committee chooses to engage and for payment of ordinary administrative expenses of the audit committee that are necessary or appropriate in carrying out its duties.

COMPOSITION AND MEETINGS

The audit committee will comprise three or more independent directors as determined by the board.  A majority of the committee members present at a meeting will constitute a quorum.

Committee members will be appointed by the board at the annual organizational meeting of the board to serve until their successors are elected.  Unless a chair is elected by the full board, the members of the committee may designate a chair by majority vote.

Each audit committee member will meet the applicable standards of independence and the determination of independence will be made by the board and as defined by Toronto Stock Exchange listing requirements.

All members of the audit committee must comply with all financial literacy requirements of the Toronto and New York stock exchanges.  To help meet these requirements, the audit committee will provide its members with annual continuing education opportunities in financial reporting and other areas relevant to the audit committee.  At least one member will qualify as an "audit committee financial expert" as defined by the Security and Exchange Commission, as determined by the board and appropriate disclosure will be made.

The committee will meet at least quarterly, or more frequently as circumstances dictate.  The committee chair will approve the agenda for the committee's meetings and any member may suggest items for consideration.  Briefing materials will be provided to the committee as far in advance of meetings as practicable; generally, one week. Meetings will be minuted and approved at the following audit committee meeting.  Copies of minutes will be provided to the external auditor whether or not they attended any meeting.

Each regularly scheduled meeting will include an in camera session of the audit committee separately with the internal audit manager and the independent auditor.
