On January 24, 2013, Rimrock Gold Corp., a Nevada corporation, formerly known as Tucana Lithium Corp. (the “Company”), entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Tucana Holdings Inc., a Nevada corporation and wholly-owned subsidiary of the Company (“Holdings”), and Rimrock Mining, Inc., a Nevada corporation (“Rimrock”), pursuant to which Holdings will merge with and into Rimrock, and Rimrock will become a wholly-owned subsidiary of the Company. On closing of the transaction, the Company will acquire all the interest in three prospective gold exploration properties known as Rimrock Property, West Silver Cloud and Pony Spur, located in northeast Nevada (the “Acquired Properties”) and will issue 17,800,000 post-split shares of its common stock, par value $0.001 (the “Common Stock”), to the sellers of the Acquired Properties as consideration for such properties. To date, the Company’s main exploration target has been the Abigail Lithium Property located in the James Bay, Quebec region of Canada.

As a closing condition to the Merger Agreement, the Company is required to effect a 1-for-8 reverse split of the issued and outstanding shares of the Common Stock (the “Reverse Stock Split”).  As a result, the issued and outstanding shares of Common Stock will decrease from 66,435,908 shares prior to the Reverse Stock Split to 8,304,488 shares following the Reverse Stock Split. The Company notified FINRA of the proposed Reverse Stock Split on January 29, 2013.
