Aura Minerals Inc. Releases Copper-Gold-Iron-Nickel Assay Results on Serrote da Laje Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 19, 2008) - Aura Minerals Inc. (TSX:ORA) (the "Company" or "Aura Minerals") is very pleased to report results of the fourth batch ("Batch 4") of diamond drill holes from the second phase infill and step-out program on its 100%-owned Arapiraca development project ("Arapiraca Project") in Alagoas State, Brazil. The results are from step-out and infill holes in the south, north-west and central zones of the Serrote da Laje deposit (the "Deposit"). These results are being incorporated into the updated resource that is expected to be released prior to the end of June.

North-West and Central Zones (see Map 1 below)

The drill holes in these zones were designed to infill known mineralization and test the potential to expand the resource. Previous Companhia Vale do Rio Doce ("Vale") drilling in these areas had been limited and previously released Aura Minerals holes indicated that mineralization should continue. These most recent results confirm the continuity of mineralization in these areas and also provide further confidence for the resource model.

Highlights from this area include:

- Hole AR-SLJE-184 which returned 53.43 metres of 0.74% Cu, 0.14 g/t Au, 22.69% Fe and 0.09% Ni;

- Hole AR-SLJE-225 which returned 65.48 metres of 0.59% Cu, 0.10 g/t Au, 16.48% Fe and 0.07% Ni;

- Hole AR-SLJE-227 which returned 58.58 metres from near surface of 0.36% Cu, 0.06 g/t Au; 14.47% Fe and 0.06% Ni;

- Hole AR-SLJE-228 which returned 49.00 metres of 0.65% Cu, 0.11 g/t Au, 16.96% Fe and 0.07% Ni;

- Hole AR-SLJE-233 which returned 9.64 metres from near surface of 1.80% Cu, 0.20 g/t Au, 10.56% Fe and 0.05% Ni;

- Hole AR-SLJE-249 which returned 68.04 metres of 0.62% Cu, 0.09 g/t Au, 18.30% Fe and 0.08% Ni; and

- Hole AR-SLJE-251 which returned 43.32 metres of 0.76% Cu, 0.14 g/t Au, 21.36% Fe and 0.08% Ni.

Southern Zone (see Map 2 below)

There had been limited drilling in the southern zone to date and the drill holes in this zone were designed to confirm previous historical drilling by Vale and to provide further confidence for the upcoming resource model. The results have been very successful and follow-up drilling is now underway to determine the extent of this area of mineralization. Also of note is that in the most southern extent of the deposit the iron, gold and nickel assays are significantly higher than in other zones which will be considered in future mine planning. The southern zone remains open laterally and at depth and is being tested by three drill rigs.

Highlights from this area include:

- Hole AR-SLJE-177 which returned 30.79 metres of 0.37% Cu, 0.23 g/t Au, 27.75% Fe and 0.14% Ni;

- Hole AR-SLJE-234 which returned 43.22 metres of 0.58% Cu, 0.09 g/t Au, 17.07% Fe and 0.09% Ni;

- Hole AR-SLJE-246 which returned 45.50 metres of 0.39% Cu, 0.22 g/t Au, 29.60% Fe and 0.13% Ni;

- Hole AR-SLJE-248 which returned 47.00 metres of 0.40% Cu, 0.12 g/t Au; 26.58% Fe and 0.12% Ni;

- Hole AR-SLJE-253 which returned 42.20 metres of 0.38% Cu, 0.17 g/t Au, 27.83% Fe and 0.12% Ni; and

- Hole AR-SLJE-254 which returned 43.12 metres of 0.36% Cu, 0.18 g/t Au, 27.47% Fe and 0.12% Ni.

Commenting on these results, Mr. Patrick Downey, President and CEO of Aura Minerals Inc., stated, "The results continue to add confidence to both the continuity and expansion potential at the Serrote da Laje deposit. The southern end of the deposit extends to the surface and the higher iron, gold and nickel grades in this zone will provide additional flexibility for blending with the shallower higher copper grade northern zone at the early stages of operation. I look forward to the new resource model and believe we will convert a significant amount of inferred to measured and indicated and add to the overall resource."

QA/QC Procedures

The Company's diamond drilling program is being conducted by Geosol-Geologia e Sondagens Ltda. The core is measured, logged, photographed and then split in half using a core saw. Half the core is retained on-site in a secure storage facility and the other half is processed through the on-site sample preparation facility under the supervision of SGS-Geosol Laboratorios Ltda. ("SGS-Geosol"). The entire half-core is crushed and pulverized and 150 gram splits of this pulp are sent directly by SGS-Geosol to their main ISO-accredited assay laboratory in Belo Horizonte, Minas Gerais State, Brazil. At this laboratory, samples are analyzed by ICP multi-element analysis (35 elements are reported); Cu is additionally analysed by acid digestion and Atomic Absorption ("AA") finish; Fe over 40% is assayed by XRF (X-Ray Refraction); and the gold, palladium and platinum content is determined by fire assay with an AA finish. Aura Minerals sends check samples to ALS Chemex and systematically puts certified standard samples and blank samples in all batches of samples sent to SGS-Geosol as a means of quality control. Additionally, SGS-Geosol has its own stringent internal QA/QC protocols.
