Ladies and Gentlemen:

Re: Registration Statement on Form F-80

With respect to the subject registration statement, we
acknowledge our awareness of the incorporation by reference therein of our
compilation report relating to the unaudited pro forma consolidated balance
sheet of Energy Metals Corporation as at September 30, 2006 and the unaudited
pro forma consolidated statement of operations for the year ended June 30, 2006
and for the three months ended September 30, 2006, dated December 7, 2006.

We are not subject to the liability provisions of Section
11 of the Securities Act of 1933 for the compilation report because it is not
considered a “report” or a “part” of a registration statement prepared or
certified by an accountant within the meaning of sections 7 and 11 of the Act.

Yours very truly,
