Aura Minerals Releases Second Batch of Exploration Drill Holes From the Aranzazu Property in Mexico Including 42.34 Metres of 3.90% Cu, 2.60 g/t Au and 38.83 g/t Ag

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 4, 2008) - 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.

This second batch of drill holes (see Map 1 and Map 2 below) was completed in 2007/08 as part of a 40,000 metre drill program prior to Aura Minerals' acquisition of the property. Aura Minerals is completing a systematic technical review of the entire drill program and results will be released on an ongoing basis as the review progresses.

These results, together with upcoming results from a planned program by Aura Minerals for Q3/Q4-2008, will form the basis for an updated National Instrument 43-101 ("NI 43-101") compliant resource estimate planned for later this year.

The results (see Table 1 below) are from the skarn mineralization generally to the east of the current mining area. This mineralized skarn has a strike extent of at least 2 kilometres and this batch of holes represents approximately 300 metres only of the strike extent. Drilling to date has been focused from surface to a depth of approximately 350 metres and the mineralization is still open down-dip.

Highlights from this most recent batch include:

- Hole 53625-3 which returned 13.00 metres of 4.47% Cu, 0.82 g/t Au and 17.08 g/t Ag and a further 7.70 metres of 6.12% Cu, 1.80 g/t Au and 40.83 g/t Ag;

- Hole 53700-1 which returned 34.00 metres of 1.68% Cu, 0.25 g/t Au and 15.32 g/t Ag;

- Hole 53775-3 which returned 18.00 metres of 2.32% Cu, 0.76 g/t Au and 19.38 g/t Ag;

- Hole 53775-4 which returned 26.00 metres of 2.16% Cu, 0.46 g/t Au and 20.18 g/t Ag;

- Hole 53775-5 which returned 38.50 metres of 1.99% Cu, 1.18 g/t Au and 27.69 g/t Ag;

- Hole 53800-1 which returned 44.00 metres of 1.24% Cu, 0.63 g/t Au and 5.80 g/t Ag;

- Hole 53800-2 which returned 89.50 metres of 1.89% Cu, 1.81 g/t Au and 28.38 g/t Ag;

- Hole 53800-3 which returned 62.00 metres of 2.11% Cu, 2.07 g/t Au and 31.07 g/t Ag and a further 66.00 metres of 2.13% Cu, 0.67 g/t Au and 18.44 g/t Ag;

- Hole 53800-4 which returned 78.25 metres of 1.81% Cu, 0.83 g/t Au and 14.92 g/t Ag;

- Hole 53800-5 which returned 59.50 metres of 1.39% Cu, 0.67 g/t Au and 7.64 g/t Ag;

- Hole 53875-1 which returned 7.72 metres of 5.54% Cu, 2.66 g/t Au and 90.10 g/t Ag;

- Hole 53875-3 which returned 78.00 metres of 1.68% Cu, 0.38 g/t Au and 19.33 g/t Ag and a further 35.00 metres of 1.82% Cu, 0.57 g/t Au, and 20.48 g/t Ag; and

- Hole 53875-4 which returned 42.34 metres of 3.90% Cu, 2.60 g/t Au and 38.83 g/t Ag.

Commenting on these results, Mr. Patrick Downey, President and CEO of Aura Minerals, stated, "These results continue to confirm the presence of high grade continuous chutes within the Aranzazu deposit and the down-dip continuity of these high grade chutes. Furthermore, the results demonstrate that the deposit is open to depth and along strike to the east and west of the current mine area, with potential for several additional high-grade chutes along this strike. We will release further drill results from the 2007/2008 program as we complete our detailed QA/QC checks.

We are also currently planning a detailed diamond drill program which will be designed to provide additional in-fill drilling for mine planning purposes and to test the down-dip extension of these chutes."
