TORONTO, June 27, 2011 /CNW/ - On June 6, 2011 Upper Canada Gold Corporation ("Upper Canada" or "the Company") (TSXV: UCC), announced that the Company had entered into a definitive purchase and sale agreement with John 3:16, LLC (the "Vendor") to purchase a fee simple interest (subject to a 3% net smelter royalty) in approximately 3,350 acres (part of the Rancho Las Mariposa Land Grant) located 15 miles north of Mariposa, California and known as the Pine Tree-Josephine Property (the "Property"). Under the terms of the original agreement the Company was required to pay the Vendor US$6 million cash and provide the Vendor with a US$6 million promissory note to be repaid 370 days following closing.  The requirement for the US$6 million promissory note has now been replaced with a requirement to provide two US$3 million non-interest bearing promissory notes, with the first to be repaid 370 days following closing and the second to be repaid 735 days following closing. The promissory notes will be secured by way of mortgage against the Property.

To date, the Company has paid deposits totalling US$175,000 to the Vendor in consideration for the exclusive right to acquire the Property.  Provided that closing has not yet occurred, on or before each of July 22 and August 22, 2011, the Company is required to remit a further US$125,000 payment on each date to an escrow agent.  All of the foregoing deposits and payments shall be credited against the cash component of the purchase price due at closing.

The completion of the acquisition is subject to a number of conditions including receipt of all necessary regulatory approvals together with the satisfaction of all covenants and conditions contained in the definitive purchase and sale agreement.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
