Aura Minerals Intersects 21.00 Metres of 7.57% Cu, 1.47 g/t Au and 38.70 g/t Ag in New Calcocita Zone

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 3, 2009) - Aura Minerals Inc. ("Aura Minerals" or the "Company") (TSX:ORA) is pleased to release additional drill hole results from its wholly owned Aranzazu Project in Zacatecas State, Mexico.

These results include the last set of holes drilled as part of the previous operator's 2007/08 40,000-metre drill program ("2007/08 Program") and drill holes completed by Aura Minerals in late 2008, which include holes drilled as part of a follow-up program to the 2007/08 Program (see Maps 1, 2 and 3: http://media3.marketwire.com/docs/0303ora.pdf).

This most recent drilling by Aura Minerals targeted the high-grade ore chutes which will become part of the new mine plan for re-start of operations. Of significant interest is that the drilling intercepted a new splay chute, the "Calcocita Zone", off the main skarn mineralization. This Calcocita Zone is approximately 15 metres true width and appears to host potential for significant high-grade mineralization just 50 metres from the existing adit. This would therefore reduce the required mine development and capital costs for the potential 2010 re-start of operations.

Highlights from Calcocita Zone include:

- Hole UAZ-009 which returned 21.00 metres of 7.57% Cu, 1.47 g/t Au and 38.70 g/t Ag;

- Hole UAZ-010 which returned 15.82 metres of 2.92% Cu, 1.37 g/t Au and 33.66 g/t Ag;

- Hole UAZ-014 which returned 15.00 metres of 1.28% Cu, 0.48 g/t Au and 20.70 g/t Ag; and

- Hole UAZ-015 which returned 16.50 metres of 2.00% Cu, 0.51g/t Au and 18.62 g/t Ag.

- Hole AZR-018 which returned 6.10 metres of 2.36% Cu, 0.77 g/t Au and 34.00 g/t Ag and a further 12.19 metres of 2.59% Cu, 1.90 g/t Au and 18.80 g/t Ag;

- Hole AZR-033 which returned 10.67 metres of 1.55% Cu, 0.27 g/t Au and 21.60 g/t Ag.

(i)includes 11.88 metres of open space

Highlights from previous operator drilling include:

- Hole 23975-1 which returned 56.00 metres of 2.19% Cu, 0.66 g/t Au and 24.30 g/t Ag;

- Hole 53450-6 which returned 37.60 metres of 4.63% Cu, 0.41 g/t Au and 46.80 g/t Ag; and

- Hole 53450-11 which returned 34.59 metres of 4.34% Cu, 0.44 g/t Au and 68.70 g/t Ag.

Commenting on these results, Mr. Patrick Downey, President and CEO of Aura Minerals, stated, "These results from the Aranzazu Project continue to confirm the continuity of the high-grade chutes within the main skarn mineralization. The new Calcocita Zone could prove to be very important in our plans to re-start operations.

We plan to follow-up this first batch with more drilling to test the continuity of the Calcocita Zone as this would add significant high-grade tonnes to the resource."
