Commerce Resources Corp. and Canadian International Minerals Inc. Amend Option Agreement for Carbo Rare Earth Property

VANCOUVER, Sept. 23, 2011 /PRNewswire/ - Commerce Resources Corp.

Under the amendment, Canadian International will immediately acquire a 100% interest in the Carbo Property by issuing an additional 8,000,000 common shares to Commerce. Commerce will retain its 2% NSR royalty on the property with no buyback right. Canadian International will also void any amounts due from Commerce for prior exploration under the original option agreement. The transaction is subject to acceptance by the TSX Venture Exchange.

Concurrently, Commerce shall subscribe for $300,000 worth of Units (the 'Units') into Canadian International's recently announced private placement. Each Unit will consist of one common share and one-half of one transferable share purchase warrant (each whole warrant, a 'Warrant'). Each Warrant will entitle Commerce to purchase one additional share of Canadian International for a period of 24 months from the closing date at a price of $0.25 per share in the first year and $0.30 per share in the second year. Commerce will also have the right of first refusal to participate in any future Canadian International financings up to 19.9% of the aggregate value of the respective offerings.

The Carbo Property comprises seven claims totaling 2,778 hectares and is accessible by all-weather gravel roads. The project is located 80 kilometres northeast of Prince George, B.C. within the Wicheeda-Carbo carbonatite camp and is directly contiguous with Spectrum Mining Corporation's Wicheeda Rare Earth Discovery. Commerce acquired the four main claims that make up the property by staking in 2005.
