Coro Mining Corp. Amends Terms of San Jorge Agreement

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Feb. 29, 2012) - Coro Mining Corp. (“Coro“ or the “Company“) (TSX VENTURE: COP) is pleased to announce that Franco-Nevada Corporation (“Franco Nevada“) and the Company have agreed to amend the terms of the Purchase Agreement by which Coro may acquire its 100% interest in Minera San Jorge (“MSJ“). Franco Nevada acquired Lumina Royalty Corp, the previous owner of MSJ in December 2011.

The amended terms for Coro to acquire 100% of MSJ are as follows;

- Option payments by Coro of US$1.25 million per year, for 10 years, payable quarterly, commencing March 31, 2012

- Coro may at any time, prepay the outstanding amount with a one-time payment equal to the net present value of the future payments, using a 5% discount rate

- A 7.5% Net Smelter Return (“NSR“) payable by Coro on all gold produced from the property

- The option payments are not payable when exceeded by the gold NSR payment for the period

- No other consideration, obligations, payments, or royalties are due to Franco Nevada, and Coro may withdraw from the Agreement at any time by not making the payments due.

Table 1 compares the amended terms with the previous acquisition terms. The companies have signed a non-binding letter of intent and are in the process of finalizing the amended agreement.

Alan Stephens, President and CEO of Coro commented, “We are very pleased that Franco Nevada has shown its willingness to modify the terms of the Purchase Agreement. The previous agreement contemplated US$9.25 million in payments over the next 15 months; the new option payment schedule allows Coro to stage its investment in the project until it has greater certainty on the ability to permit the project in Mendoza province. The Company will provide its shareholders with an update of the status of San Jorge shortly.“

As of December 31, 2011 the Company had approximately CA$12 million in cash, and is well funded to advance its projects.
