Aura Minerals Provides Corporate Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 28, 2012) - Aura Minerals Inc. ("Aura Minerals" or the "Company") (TSX:ORA) is pleased to provide the following update on the upsizing of the revolving credit facility, the implementation of a gold hedging program and the status of the feasibility study on the Serrote de Laje Project (formerly known as the Arapiraca Project) in Brazil (the "Serrote Project").

Credit Facility Upsizing

Although the Company expects to generate positive free cash flow in 2012 based on current metal prices, management has negotiated an increase in the revolving credit facility to $45 million, from $25 million, to fund working capital for growth. Closing of the upsizing is expected to be in late March or early April, 2012.

Gold Hedging Program

In conjunction with the implementation of the new mine plans at the Sao Francisco and Sao Vicente gold mines in Brazil and the upsizing of the credit facility, the Company has implemented a gold hedging program to take advantage of current high gold prices and secure cash flows at these higher cost operations. Under this program, the Company has hedged 80,000 ounces of gold production between April 2012 and June 2014, using a series of zero-cost put/call collars having a put/floor price of $1,700 per ounce and an average call/ceiling price of $1,812 per ounce.

Serrote Project Feasibility Study

On July 12, 2011, Aura Minerals announced that SNC-Lavalin Inc. and its Brazilian subsidiary, SNC-Lavalin Minerconsult Engenharia Ltda., had been awarded the definitive feasibility study on the Serrote Project. Work on the design and sizing of the mine is ongoing, with the feasibility study now scheduled for completion in the second quarter of 2012 as opposed to the first quarter of 2012.

The feasibility study will focus on developing the Serrote Project as an open pit mine that will supply sulphide ore to a concentrator at a rate of 8-12 million tonnes per year, producing copper in concentrate with gold credits, with potential for iron in magnetite concentrate. With all critical permits in place, and with the excellent infrastructure in the vicinity of the project, and assuming a positive result of the feasibility study, the Company expects to commence development, contracting and negotiations for project financing during the last half of 2012.
