Mala Noche Signs San Dimas Definitive Purchase Agreements

Vancouver, July 30, 2010 - Mala Noche Resources Corp. (TSX VENTURE: MLA) (the "Company") (to be renamed "Primero Mining Corp.") announced today that it has signed a definitive asset purchase agreement and share purchase agreement with subsidiaries of Goldcorp Inc. (the "Vendors") in relation to the previously announced acquisition of 100% of the San Dimas gold-silver mine in Mexico. Closing will occur as soon as practicable.

The purchase price of US$510 million is to be comprised of US$216 million in cash, US$184 million in shares of the Company (representing approximately 36%), a US$60 million convertible note and a US$50 million 5-year note all payable to the Vendors.

This acquisition achieves management's goal of acquiring a well known producing precious metals mine. San Dimas consists of three underground gold-silver mines located in Mexico's San Dimas district, on the border of Durango and Sinaloa states. San Dimas produced 113,000 ounces of gold and 5.1 million ounces of silver in 2009. The San Dimas gold-silver deposit is one of the most significant precious metal deposits in Mexico. The district was first mined in 1757 with historical production from the San Dimas district estimated at 11 million ounces of gold and 582 million ounces of silver, affirming it as a world class epithermal mining district.

Mala Noche's financial advisor for this transaction was Canaccord Genuity Corp. and legal counsel in Canada was Lang Michener LLP (Vancouver).
