Aura Minerals Releases Additional Assay Results for the Aranzazu Copper-Gold-Silver Project in Mexico

Aura Minerals Inc. ("Aura Minerals" or the "Company") (TSX:ORA) is pleased to
release an additional 56 drill holes from the ongoing infill and extension drill
program at its wholly-owned copper-gold-silver Aranzazu Project in Zacatecas
State, Mexico. The most recent Aura Minerals drilling was designed to target
zones southeast along strike - along the Glory Hole-Tiro Azules to Cabrestante
zones. The drilling continues to show the high-grade potential of the Aranzazu
Project orebody.


Of the 56 reported drill holes, 40 drill holes had intercepts of greater than
1.0% Cu with significant gold and silver values. Highlights include (see Table
1, Map 1 and Map 2 below):




--  Hole AZC-089 which returned 25.5 metres of 1.08% Cu, 0.8 g/t Au and 16.6
    g/t Ag;
--  Hole AZR-073 which returned 7.6 metres of 3.22% Cu, 3.0 g/t Au and 27.9
    g/t Ag;
--  Hole AZR-077 which returned 13.7 metres of 1.27% Cu, 2.4 g/t Au and 19.4
    g/t Ag;
--  Hole AZR-086 which returned 15.2 metres of 1.28 % Cu, 1.4 g/t Au and
    17.4 g/t Ag;
--  Hole AZR-087 which returned 21.3 metres of 4.42% Cu, 2.9 g/t Au and 44.4
    g/t Ag;
--  Hole AZR-088 which returned 24.4 metres of 1.19% Cu, 1.3 g/t Au and 14.2
    g/t Ag;
--  Hole AZR-091 which returned 13.7 metres of 1.74% Cu, 1.0 g/t Au and 18.7
    g/t Ag;
--  Hole AZR-093 which returned 18.3 metres of 1.80% Cu, 1.2 g/t Au and 21.2
    g/t Ag;
--  Hole AZR-105 which returned 21.3 metres of 1.80% Cu, 1.5 g/t Au and 37.1
    g/t Ag;
--  Hole AZR-115 which returned 15.2 metres of 1.96% Cu, 2.1 g/t Au and 34.8
    g/t Ag;
--  Hole AZR-121 which returned 3.1 metres of 3.59% Cu, 5.5 g/t Au and 62.1
    g/t Ag;
--  Hole AZR-126 which returned 16.8 metres of 1.40% Cu, 1.5 g/t Au and 17.8
    g/t Ag;
--  Hole AZR-136 which returned 13.7 metres of 2.49% Cu, 2.8 g/t Au and 33.5
    g/t Ag; and
--  Hole AZR-137 which returned 6.1 metres of 2.40% Cu, 3.7 g/t Au and 25.2
    g/t Ag.



The drilling continues to intercept higher than average gold grades as drilling
moves progressively along strike to the east of the Arroyos Azules zone, which
is the first area scheduled for mining as part of the planned restart of
operations (see News Releases No. 2010-09 and No. 2010-03 dated April 5, 2010
and February 15, 2010 respectively). This drilling was designed as follows:




--  Infill drilling along the Arroyos Azules zone to continue underground
    mine planning;
--  Near surface definition drilling in the Glory Hole-Tiro Azules to
    Cabrestante zones, which is being evaluated as a potential; open-pit
    operation in conjunction with underground operations; and
--  Ongoing drilling along strike as part of a planned new resource estimate
    for the deposit.



Commenting on the above, Mr. Patrick Downey, President and CEO of Aura Minerals,
stated, "Ongoing infill drilling for near-term mine planning and upgrading of
resource classification continues to highlight the high-grade nature of the
copper and gold resources at the Aranzazu Project. As we continue with the
planned drill programs, including the deep drill program from which we recently
released the first results (see News Release #2010-15 dated August 5, 2010), we
are very encouraged that the resource will be extended both along strike and at
depth."

Qualified Person

Exploration at the Aranzazu Project is being conducted under the supervision of
Mr. Alan Hitchborn, P.Geo., who is the Company's Qualified Person as defined by
NI 43-101. Mr. Hitchborn has also reviewed and approved the contents of this
news release as applicable.


Quality Assurance and Quality Control ("QA/QC") Procedures for the Aranzazu Project

Aura Minerals is presently drilling at the Aranzazu Project utilizing both core
and reverse circulation drill rigs. The drilling is conducted by Layne de
Mexico. The reverse circulation drill uses a bit sized from 5.5 inches to 4.75
inches. The core program utilizes HQ-sized core and then stepping down to
NQ-sized core as required. Samples are collected on a 1.5 metre sample interval.
The reverse circulation drill cuttings are split at the drill rig. The samples
collected consist of an approximate 25% split of the total material recovered
from the interval sampled. This material is shipped directly to the Stewart
Group de Mexico ("Stewart Mexico") sample preparation facility in Zacatecas,
Mexico and processed utilizing the same sample preparation protocol as used for
the core samples discussed below. Assays are completed at the ISO 9001-2008
certified Eco Tech Laboratory Limited ("Eco Tech Stewart"), a subsidiary of the
Stewart Group Ltd., in Kamloops, British Columbia, Canada. Diamond drilling core
is logged, photographed and then split in half using a diamond core saw. Half
the core is retained off-site in a secure storage facility and the other half is
sampled, secured in sealed, labeled bags and then transported to the Stewart
Mexico facility in Zacatecas, Mexico and processed utilizing the same
preparation protocol discussed below. Assays are completed at the Eco Tech
Stewart laboratory in Kamloops, B.C. The entire half-core and reverse
circulation drill cuttings are crushed to 95% passing 2 millimetres, split and
pulverized to 95% passing 150 mesh, split again, and a 150 gram sample sent for
assay. Gold assays are determined by fire assay with an AA finish, over limit
assays are determined by fire assay with a gravimetric finish. Silver, copper,
lead and zinc assays are determined by a four acid digestion with an ICP-MS
finish. Molybdenum assays are determined by aqua regia digestion followed by an
ICP-OES finish. Silver overlimits are determined by a fire assay with a
gravimetric finish. The Company systematically inserts certified standard
samples, sample duplicates in a non-sequential order and blank samples in all
batches of samples sent to Stewart Mexico and Eco Tech Stewart as a means of
quality control. Additionally, Stewart Mexico and Eco Tech Stewart have their
own stringent internal QA/QC protocols. Check samples are systematically sent to
the ALS Chemex lab in Vancouver, Canada. Chain of custody of drill samples is
maintained throughout the process with the use of numbered seal tags closing
sample bags and third party professional transportation of samples to the
laboratories. Each stage of sample handling is recorded in log sheets and
receipts obtained from each party involved.
