(1) As a result of (a) Robert Ross McEwen’s (“Mr. McEwen”) ownership interests in Evanachan Limited, a corporation organized under the laws of Ontario, Canada (“Evanachan”), McEwen Trading LP, a limited partnership organized under the laws of Ontario, Canada (“McEwen Trading”) and Lexam Explorations Inc., a corporation organized under the laws of Canada (“Lexam”) (such ownership in Evanachan, McEwen Trading and Lexam collectively being the “McEwen Ownership Interests”), (b) the terms of the Agreement for the Purchase and Sale of Mineral Interests and Financing of Rubicon Minerals Corporation (“Rubicon”), dated May 18, 2007 (the “Purchase Agreement”) and (c) Rule 13d-5(b)(1) (“Rule 13d-5(b)(1)”) of the Exchange Act of 1934, as amended (the “Exchange Act”), Mr. McEwen, Evanachan, McEwen Trading and Lexam Explorations (U.S.A.) Inc. (“Lexam U.S.A.”), a Colorado corporation and indirectly wholly-owned subsidiary of Lexam, may be deemed to be a “group” and such “group” may be deemed to have acquired beneficial ownership for purposes of Section 13(d) of the Exchange Act, of all of the common shares (the “Common Shares”) of Rubicon deemed beneficially owned by such “group.” For purposes of this Amendment No. 5 to Schedule 13D, Mr. McEwen does not affirm the existence of such group that includes Lexam U.S.A.

(3) As a result of (a) the McEwen Ownership Interests, (b) the Purchase Agreement and (c) Rule 13d-5(b)(1) (as more fully described in footnote (1)), Mr. McEwen may be deemed to have voting and dispositive power over the following Common Shares: (i) 38,750,000 Common Shares held by Evanachan, (ii) 6,964,357 Common Shares held by McEwen Trading, and (iii) 0 Common Shares held by Lexam U.S.A., a company that is indirectly owned by Lexam, a company in which, as of August 19, 2010, Mr. McEwen owns 49.4% of the outstanding common shares.

(4) As a result of the sales of 2,181,129 Common Shares by Lexam U.S.A. described more fully in this Amendment No. 5 to Schedule 13D, Lexam U.S.A. no longer holds any Common Shares. As described further in footnote (3) above, prior to such sales, Mr. McEwen may have been deemed to have shared voting power and shared dispositive power over the Common Shares held by Lexam U.S.A. with Lexam U.S.A. As a result of such sales, Mr. McEwen no longer has shared voting power or shared dispositive power over any Common Shares.

(5) As described in footnote (1) above and the Explanatory Note below, Mr. McEwen may be deemed to be part of a group with Evanachan, McEwen Trading and Lexam U.S.A., and such group may be deemed to beneficially own, in the aggregate, 45,714,357 Common Shares.

(6) Such approximate percentage was based on information provided by Rubicon as of June 30, 2010. As described in footnote (1) above and the Explanatory Note below, Mr. McEwen may be deemed to be part of a group with Evanachan and McEwen Trading, and such group may be deemed to beneficially own, in the aggregate, 45,714,357 Common Shares.

EXPLANATORY NOTE This Amendment No. 5 to Schedule 13D (“Amendment No. 5 to Schedule 13D”) relating to the common shares, no par value per share (the “Common Shares”) of Rubicon Minerals Corporation (“Rubicon”) is being filed individually by Robert Ross McEwen (“Mr. McEwen”) pursuant to Rule 13d-1(k)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) to reflect the disposition by Lexam U.S.A. of Common Shares, as more fully described in Item 5. As a result of (a) Mr. McEwen’s 100% interest in Evanachan Limited, a corporation organized under the laws of Ontario, Canada (“Evanachan”), 100% ownership interest in McEwen Trading and ownership in Lexam Explorations Inc., a corporation organized under the laws of Ontario, Canada (“Lexam”) (as more fully described in this Explanatory Note below) (such ownership in Evanachan, McEwen Trading and Lexam collectively being the “McEwen Ownership Interests”), (b) the terms of the Purchase Agreement (as more fully described in footnote (1) above) and (c) Rule 13d-5(b)(1) of the Exchange Act (“Rule 13d-5(b)(1)”), Mr. McEwen, Evanachan, McEwen Trading and Lexam Explorations (U.S.A.) Inc. (“Lexam U.S.A.”) may be deemed to be a “group” and such “group” may be deemed to have acquired beneficial ownership for purposes of Section 13(d) of the Exchange Act, of all of the Common Shares beneficially owned by such “group.” Lexam U.S.A. is indirectly wholly-owned by Lexam, a Canadian public company that is traded on the TSX Venture Exchange and in which, as of August 19, 2010, Mr. McEwen owns 49.4% of the outstanding common shares. For purposes of this Amendment No. 5 to Schedule 13D, Mr. McEwen does not affirm the existence of such group that includes Lexam U.S.A. As a result of (a) the McEwen Ownership Interests, (b) the Purchase Agreement and (c) Rule 13d-5(b)(1), Mr. McEwen may be deemed to beneficially own the Common Shares, in the aggregate, beneficially owned by Evanachan, McEwen Trading and Lexam U.S.A. Mr. McEwen expressly disclaims beneficial ownership with respect to the Common Shares beneficially owned by Evanachan, McEwen Trading and Lexam U.S.A., except to the extent of Mr. McEwen’s direct pecuniary interest therein.

Item 4. Purpose of Transaction
Item 4 is hereby amended as follows: (a) Lexam U.S.A. disposed of Common Shares as described in Item 5 to this Amendment No. 5 to Schedule 13D to fund working capital for its exploration activities and general operations. The disposition of Common Shares by Lexam U.S.A. does not reflect the views of Lexam U.S.A., Evanachan, McEwen Trading or Mr. McEwen regarding Rubicon’s current or future business prospects. Mr. McEwen beneficially owns 45,714,357 Common Shares and has no current intention to dispose of any of his Common Shares.

Item 5. Interest in Securities of the Issuer
Item 5 is hereby amended as follows: (a) As a result of the Purchase Agreement and Rules 13d-3(d)(1)(i) and 13d-5(b)(1) of the Exchange Act, each of Mr. McEwen, Evanachan, McEwen Trading and Lexam U.S.A. may be deemed to have acquired beneficial ownership of 61,696,428 Common Shares (as adjusted for rounding) acquired by Evanachan, McEwen Trading and Lexam U.S.A. on May 18, 2007. After Lexam U.S.A.’s disposition of 1,944,200 Common Shares reported in Amendment No. 1 to Schedule 13D, filed with the SEC on February 21, 2008 (“Amendment No. 1 to Schedule 13D”), Lexam U.S.A.’s disposition of 2,073,900 Common Shares as reported in Amendment No. 2 to Schedule 13D, filed with the SEC on November 3, 2008 (“Amendment No. 2 to Schedule 13D”), Evanachan’s disposition of warrants to purchase 3,660,714 Common Shares as reported in Amendment No. 3 to Schedule 13D, filed with the SEC on May 1, 2009 (“Amendment 3 to Schedule 13D”), McEwen Trading’s disposition of warrants to purchase 3,571,421 Common Shares as reported in Amendment No. 3 to Schedule 13D, McEwen Trading’s disposition of 178,500 Common Shares as reported in Amendment No. 3 to Schedule 13D, Lexam U.S.A.’s disposition of 148,000 Common Shares as reported in Amendment No. 3 to Schedule 13D, Lexam

U.S.A.’s disposition of 2,224,200 Common Shares as reported in Amendment No. 4 to Schedule 13D filed with the SEC on October 9, 2009, and Lexam U.S.A.’s disposition of 2,181,129 Common Shares as reported in this Amendment No. 5, each of Mr. McEwen, Evanachan and McEwen Trading may be deemed to have beneficial ownership of 45,714,357 Common Shares, which represents approximately 21.42% of the outstanding Common Shares, which includes:

(i) 38,750,000 Common Shares held by Evanachan, a company wholly owned by Mr. McEwen, and

(ii) 6,964,357 Common Shares held by McEwen Trading, a limited partnership 100% owned by Mr. McEwen, and

(iii) 0 Common Shares held by Lexam U.S.A., a company that is indirectly owned by Lexam, a Canadian public company traded on the TSX Venture Exchange and of which, as of August 19, 2010, Mr. McEwen owns 49.4% of the outstanding common shares.

After Lexam U.S.A.’s disposition of 2,181,129 Common Shares, Lexam U.S.A. beneficially owns (and therefore Lexam may be deemed to beneficially own) 0 Common Shares, which represents approximately 0% of the Common Shares, and which beneficial ownership excludes Common Shares beneficially owned by Mr. McEwen, Evanachan and McEwen Trading, the beneficial ownership of which Lexam U.S.A. and Lexam disclaim pursuant to Rule 13d-4 of the Exchange Act, except to the extent of Lexam U.S.A.’s direct pecuniary interest therein.

Evanachan beneficially owns 38,750,000 Common Shares, which represents approximately 18.15% of the Common Shares, and which beneficial ownership excludes the Common Shares beneficially owned by McEwen Trading and Lexam U.S.A., the beneficial ownership of which Evanachan disclaims pursuant to Rule 13d-4 of the Exchange Act, except to the extent of Evanachan’s direct pecuniary interest therein.

Mr. McEwen beneficially owns 45,714,357 Common Shares, which represents approximately 21.42% of the Common Shares, which consists of (i) 38,750,000 Common Shares held by Evanachan and (ii) 6,964,357 Common Shares held by McEwen Trading.

McEwen Trading beneficially owns 6,964,357 Common Shares, which represents approximately 3.26% of the Common Shares, and which beneficial ownership excludes the Common Shares beneficially owned by Evanachan and Lexam U.S.A., the beneficial ownership of which McEwen Trading disclaims pursuant to Rule 13D-4 of the Exchange Act, except to the extent of McEwen Trading’s direct pecuniary interest therein.

Although neither McEwen Trading nor Evanachan has disposed of any Common Shares, the percentage of ownership that each of McEwen Trading, Evanachan and Mr. McEwen may be deemed to beneficially own (excluding Common Shares not owned by each such person) has decreased since such person’s Amendment No. 4 to Schedule 13D, but only as a result of an increase in Rubicon’s reported issued and outstanding Common Shares.

(b) The information contained on the cover page to this Amendment No. 5 to Schedule 13D is incorporated by reference to this Item 5(b).

(c) Lexam U.S.A. disposed of 2,181,129 Common Shares between September 29, 2009, the date of Amendment No. 4 to Schedule 13D, and August 19, 2010 in open market sales. Annex A hereto sets forth information about sales effected by Lexam U.S.A. in the past 60 days.

(d) The information contained in the Explanatory Note and Item 5(a) of this Amendment No. 5 to Schedule 13D is incorporated by reference to this Item 5(b).

(e) Not applicable.
