INTRODUCTORY STATEMENT

     This registration statement on Form S-8 registers the following: (1) 4,653,201 common shares (“Common Shares”) of Fronteer Development Group Inc. (the “Registrant”) issuable pursuant to options outstanding under the 2007 Stock Option Plan, (2) an additional 3,650,759 Common Shares reserved for issuance under the 2007 Stock Option Plan, and (3) 518,050 Common Shares reserved for issuance under the Acquisition Performance Incentive Share Plan, which was adopted by the Registrant in connection with a plan of arrangement with NewWest Gold Corporation effected pursuant to the order of the Supreme Court of British Columbia dated September 19, 2007. Pursuant to the arrangement agreement setting out the terms and conditions of the plan of arrangement between the Registrant and NewWest Gold Corporation dated as of July 27, 2007, on September 24, 2007, the effective date of the arrangement, all of the options outstanding under the existing stock option plan of NewWest Gold Corporation were replaced by options to purchase Common Shares under the Acquisition Performance Incentive Share Plan, whereby the Registrant agreed to issue to the holder thereof a number of Common Shares equal to the number of common shares of NewWest Gold Corporation which such holder was entitled to receive upon the exercise of such holder's NewWest Gold Corporation option, multiplied by 0.26 (rounded down to the nearest whole number).

     If a stock option issued under the 2007 Stock Option Plan expires or is cancelled without the recipient having acquired all of the Common Shares to which he or she was entitled, the remaining Common Shares shall be released from their allocation and reservation and shall be again available for the purposes of the 2007 Stock Option Plan.

Item 4. Description of Securities.

Item 5. Interests of Named Experts and Counsel.

     None.

Item 6. Indemnification of Directors and Officers.

Applicable Laws of Ontario

     Under the Business Corporations Act (Ontario) (the “OBCA”), the Registrant may indemnify a present or former director or officer or person who acts or acted at the Registrant’s request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal, administrative, investigative or other proceeding in which he is involved because of that association with the Registrant or other entity.

     Further, the Registrant may advance money to a director, officer or other individual for the costs, charges and expenses of a proceeding referred to above, but the individual shall repay the money if the individual does not fulfill the conditions set forth in the following paragraph.

     The Registrant shall not indemnify an individual under the first paragraph above unless the individual acted honestly and in good faith with a view to the best interests of the Registrant or, as the case may be, to the best interests of the other entity for which the individual acted as a director or officer or in a similar capacity at the Registrant’s request.

     In addition to the foregoing, if the matter is a criminal or administrative action or proceeding that is enforced by a monetary penalty, the Registrant shall not indemnify an individual under the first paragraph above unless the individual had reasonable grounds for believing his conduct was lawful.

     Further, the Registrant may, with the approval of a court, indemnify an individual referred to in the first paragraph above, or advance moneys as set forth under the second paragraph above, in respect of an action by or on behalf of the Registrant or other entity to obtain a judgment in its favor, to which the individual is made a party because of the individual’s association with the Registrant or other entity as described in the first paragraph above, against all costs, charges and expenses reasonably incurred by the individual in connection with such action, if the individual fulfils the conditions set forth in the third paragraph above.

     Despite the first paragraph above, an individual referred to in that paragraph is entitled to indemnity from the Registrant in respect of all costs, charges and expenses reasonably incurred by the individual in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the individual is subject because of the individual’s association with the Registrant or other entity as described in the first paragraph above, if the individual seeking an indemnity (a) was not judged by a court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done; and (b) fulfils the conditions set out in paragraphs three and four above.

     Under the OBCA, the Registrant may purchase and maintain insurance for the benefit of any person referred to in the first paragraph under this heading against the liability incurred by the person, (a) in his or her capacity as a director or officer of the Registrant; or (b) in his or her capacity as a director or officer, or similar capacity, of another entity where the person acts or acted in that capacity at the Registrant's request.

     Bylaws

     Subject to the limitations contained in the OBCA, the by-laws of the Registrant indemnify a director or officer, a former director or officer, or a person who acts or acted at the Registrant’s request as a director or officer of a corporation in which the Registrant is or was a shareholder or creditor (or a person who undertakes or has undertaken any liability on behalf of the Registrant or any such body corporate) and their heirs and legal representatives of any such person against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by such person in respect of any civil, criminal, or administrative action or proceeding to which such person was made a party by reason of being or having been a director or officer of the Registrant or other corporation if such person acted honestly and in good faith with a view to the best interests of the Registrant, and, in the case of a criminal or administrative action or proceeding that is enforced by monetary penalty, such person had reasonable grounds for believing that his conduct was lawful. Subject to the limitations contained in the OBCA, the Registrant may purchase and maintain such insurance for the benefit of its directors and officers as such, as the board may from time to time determine.

     Insurance

     A policy of directors’ and officers’ liability insurance is maintained by the Registrant which insures directors and officers for losses as a result of claims against the directors and officers of the Registrant in their capacity as directors and officers and also reimburses the Registrant for payments made pursuant to the indemnity provisions under the by-laws of the Registrant and the OBCA.

     Commission Position on Indemnification

     Insofar as indemnification for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Commission such indemnification is against public policy in the United States as expressed in the Securities Act and is therefore unenforceable.

II-5

---

			(i)	To include any prospectus required by Section 10(a)(3) of the Securities Act;
			(ii)	To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represents no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
			(iii)	To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
		provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8, or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement.
		(2)	That for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
		(3)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
	(b)	The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act, (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
	(h)	Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
