This will allow the new company to combine their talents, and the result will be a company with an outstanding technical and financial team, and the funds in place to continue with the primary goal of becoming mine finders within the Snow Lake project located in Manitoba, Canada. I strongly urge the Rockcliff shareholders to vote in favour of the amalgamation."
