CODE OF BUSINESS CONDUCT AND ETHICS
FORDIRECTORS, OFFICERS AND EMPLOYEES OFAUGUSTA
RESOURCE CORPORATION

Augusta Resource Corporation (the
Company) is committed to the highest standards of legal and ethical
business conduct. This Code of Business Conduct and Ethics (the Code)
summarizes the legal, ethical and regulatory standards that the Company must
follow and is a reminder to our directors, officers and employees, of the
seriousness of that commitment. Compliance with this Code and high standards of
business conduct is mandatory for every employee of the Company.

INTRODUCTION

Our business is becoming
increasingly complex in terms of the geographies in which we function and the
laws with which we must comply. To help our directors, officers and employees
understand what is expected of them and to carry out their responsibilities, we
have created this Code of Business Conduct and Ethics. Joseph Longpré, our
Ethics Officer will have the primary responsibility of overseeing adherence to
the Code.

This Code is not intended to be a
comprehensive guide to all of our policies or to all your responsibilities under
law or regulation. It provides general parameters to help you resolve the
ethical and legal issues you encounter in conducting our business. Think of this
Code as a guideline, or a minimum requirement, that must always be followed. If
you have any questions about anything in the Code or appropriate actions in
light of the Code, you may contact Joseph Longpré, the Companys Ethics Officer
or the Chairman of the Audit Committee.

We expect each of our directors,
officers and employees to read and become familiar with the ethical standards
described in this Code and to affirm your agreement to adhere to these standards
by signing the Compliance Certificate that appears at the end of this Code.
Violations of the law, our corporate policies, or this Code may lead to
disciplinary action, including dismissal.

Certain representatives may be
required to adhere to this Code and as such will be asked to execute the
Compliance Certificate that appears at the end of this Code as their agreement
to comply with this Code in the same manner as applicable to our directors,
officers and employees..

|I. | We Insist on Honest and Ethical Conduct By All of Our
      Directors, Officers, Employees and Other
  Representatives
|-- | ----------------------------------------------------------------------------------------------------------------------

We have built our business based
on quality employees and representatives who adhere to the very highest
standards of honesty, ethics and fairness in our dealings with all of our
business contacts. We place the highest value on the integrity of our directors,
our officers and our employees and demand this level of integrity in all our
dealings. We insist on not only ethical dealings with others, but on the ethical handling of
actual or apparent conflicts of interest between personal and professional
relationships.

---

**Fair Dealing**

Directors, officers and employees
are required to deal honestly and fairly with our business partners, suppliers,
competitors and other third parties.

In our dealings with business
partners, suppliers, competitors and other third parties, we:

- Prohibit bribes, kickbacks or any other form of improper payment, direct or
  indirect, to any representative of government, labor union, supplier or other
  business partner in order to obtain a contract, some other commercial benefit
  or government action;
- Prohibit our directors, officers and employees from accepting any bribe,
  kickback or improper payment from anyone;
- Prohibit gifts or favors of more than nominal value to or from our
  customers or suppliers;
- Limit marketing and client entertainment expenditures to those that are
  necessary, prudent, job-related and consistent with our policies;
- Require clear and precise communication in our contracts, our advertising,
  our literature, and our other public statements and seek to eliminate
  misstatement of fact or misleading impressions;
- Protect all proprietary data our customers or suppliers provide to us as
  reflected in our agreements with them; and
- Prohibit our representatives from otherwise taking unfair advantage of our
  customers or suppliers, or other third parties, through manipulation,
  concealment, abuse of privileged information or any other unfair-dealing
  practice.

**Conflicts of Interest;
Corporate Opportunities**

Our directors, officers and
employees should not be involved in any activity that creates or gives the
appearance of a conflict of interest between their personal interests and the
interests of the Company. In particular, without the specific permission of
Joseph Longpré, our Ethics Officer or our Board of Directors (including
contracts approved by our Board of Directors), no director, officer or employee,
or a member of his or her family shall, unless disclosed to the Company:

- Be a consultant to, or a director, officer or employee of, or otherwise
  operate an outside business that:

Directors, officers, and
employees must immediately notify Joseph Longpré, Ethics Officer or the Chair of
our Audit Committee of the existence of any actual or potential conflict of
interest. The circumstances will be reviewed for a decision on whether a
conflict of interest is present, and if so, what course of action is to be
taken.

Confidentiality and Corporate Assets

Our directors, officers and
employees are entrusted with our confidential information and with the
confidential information of our business partners. This information may include
(1) technical or scientific information about current and future projects or
endeavors, (2) business or marketing plans or projections, (3) earnings and
other internal financial data, (4) personnel information, (5) lists of current,
past and potential business partners and (6) other non-public information that,
if disclosed, might be of use to our competitors, or harmful to our business
partners. This information is our property, or the property of our business
partners, and in many cases was developed at great expense. Unless authorized by
written approval or required by applicable law, our directors, officers and
employees shall not:

- Discuss confidential information with or in the presence of any
  unauthorized persons, including family members and friends;

|II. | We Provide Full, Fair, Accurate, Timely and
      Understandable Disclosure
|--- | ---------------------------------------------------------------------------

We are committed to providing our
stockholders and investors with full, fair, accurate, timely and understandable
disclosure in the reports that we file with the Securities Commissions in
applicable jurisdictions. To this end, our directors, officers and employees
shall:

- Not make false or misleading entries in our books and records for any
  reason;
- Not condone any undisclosed or unrecorded bank accounts or assets
  established for any purpose;

  reasonable assurances to management that all transactions are properly
  recorded;
- Maintain books and records that accurately and fairly reflect our
  transactions;
- Prohibit the establishment of any undisclosed or unrecorded funds or
  assets;
- Maintain a system of internal controls that will provide reasonable

  periodic reports are being prepared;
- Present information in a clear and orderly manner and avoid the use of
  unnecessary legal and financial language in our periodic reports; and
- Not communicate to the public any nonpublic information except through, or
  as approved by, our Chief Financial Officer or Chief Executive Officer.

|Code of Ethics | Page 4

|III. | We Comply With all Laws, Rules and
    Regulations
|---- | --------------------------------------------------

We will comply with all laws and
governmental regulations that are applicable to our activities, and expect all
our directors, officers and employees to obey the law. Specifically, we are
committed to:

- Maintaining a safe and healthy work environment;
- Promoting a workplace that is free from discrimination or harassment based
  on race, color, religion, sex, age, national origin, disability or other
  factors that are unrelated to the Companys business interests;
- Supporting fair competition and laws prohibiting restraints of trade and
  other unfair trade practices;
- Conducting our activities in full compliance with all applicable
  environmental laws;
- Keeping the political activities of our directors, officers and employees
  separate from our business;
- Prohibiting any illegal payments, gifts, or gratuities to any government
  officials or political party;
- Prohibiting the unauthorized use, reproduction, or distribution of any
  third partys trade secrets, copyrighted information or confidential
  information;
- Complying with all applicable securities laws or any provisions of
  applicable law relating to fraud against stockholders; and
- Not tolerating any behavior that could constitute securities fraud, mail
  fraud, bank fraud, or wire fraud.

Our directors, officers and
employees are prohibited from trading our securities while in possession of
material, nonpublic (inside) information about the Company. Our Corporate
Disclosure and Share Trading Policy describes the nature of inside information
and the related restrictions on trading.

REPORTING AND EFFECT OF VIOLATIONS

Compliance with the Code is,
first and foremost, the individual responsibility of every director, officer and
employee. We attempt to foster a work environment in which ethical issues and
concerns may be raised and discussed with supervisors or with others without the
fear of retribution. It is our responsibility to provide a system of reporting
and access when you wish to report a suspected violation, or to seek counseling,
and the normal chain of command cannot, for whatever reason, be used.

|Code of Ethics | Page 5
|-------------- | ------

---

**Administration**

Our Board of Directors and Audit
Committee have established the standards of business conduct contained in this
Code and oversee compliance with this Code. They have also charged the Ethics
Officer to ensure adherence to the Code. While serving in this capacity, the
Ethics Officer reports directly to the Board of Directors.

Training on this code will be
included in the orientation of new employees and provided to existing directors,
officers, and employees on an on-going basis. To ensure familiarity with the
Code, directors, officers, and employees will be asked to read the Code and sign
a Compliance Certificate annually.

**Reporting Violations and
Questions**

Directors, officers, and
employees must report, in person or in writing, any known or suspected
violations of laws, governmental regulations or the Code, to either the Ethics
Officer or the Chairman of the Audit Committee of our Board of Directors.
Additionally, directors, officers, and employees may contact the Ethics Officer
or the Chairman of the Audit Committee with a question or concern about the Code
or a business practice. Any questions or violation reports will be addressed
immediately and seriously, and can be made anonymously. If you feel
uncomfortable reporting suspected violations to these individuals, you may
report matters to our outside counsel. The address and telephone number of these
individuals are listed under Reporting Contacts at the end of this Code.

It is not sufficient to report a
suspected violation of the Code to a co-worker or to any person other than one
of the individuals designated above.

Upon receipt of a complaint under
the Code, the Company will investigate the complaint and will involve agencies
and resources outside the Company if and/or when such outside involvement
appears advisable or necessary. The report and investigation will be kept
confidential to the extent consistent with the need for a thorough investigation
and response and taking into consideration the Companys disclosure obligations
and requirements.

**Consequences of a
Violation**

If it is determined that a
director, officer or employee of the Company has violated the Code, the Company
will take appropriate action including, but not limited to, disciplinary action,
up to and including termination of employment. If it is determined that a
non-employee (including any consultant, contractor, subcontractor, or other
agent) has violated the Code, the Company will take appropriate corrective
action, which could include severing the consultant, contractor, subcontractor,
or agency relationship. In either event, the Company will take necessary
corrective action reasonably calculated to address and to correct the alleged
violation.

|Code of Ethics | Page 6
|-------------- | ------

---

We will not allow any
retaliation against a director, officer or employee who acts in good faith in
reporting any violation.

The Company is committed to
maintaining an environment in which people feel free to report all suspected
incidents of inaccurate financial reporting or fraud. No retaliatory action will
be taken against any person who reports any conduct which he or she reasonably
believes may violate the Code. In addition, no retaliatory action will be taken
against any individual who in good faith assists or participates in an
