¹ Please see cautionary note at the end of this press release.

Mr. Jim Bannantine, the Company's President and Chief Executive Officer stated, "Aura finished 2012 with a good fourth quarter and demonstrated an upward trend, which is shown by our steady and growing operating cash flow quarter on quarter. This appears to be continuing into 2013 as on a pro-rata, year-to-date basis, the Company has been performing to previously circulated 2013 guidance. Management reconfirms this guidance.

We have made significant operational improvements and addressed the challenges that impacted our existing operations during 2012 with logical and cost-efficient solutions. We have also made significant progress on our expansion and development projects, the future cash flows from which are expected to replace the income stream that we forego following the closure of the Brazilian gold mines. Consideration is being given to exchanging - for value - the assets of the Brazilian operating mines into one or more junior mining companies that will be developing and building new mining projects.

The Aranzazu expansion is on schedule and on budget and we have awarded the partial roasting facility which is expected to substantially reduce the level of Arsenic in the concentrate. Serrote's development is on schedule and below budget. The required land acquisitions have been substantially completed and we have awarded the engineering and the contracts for the major equipment required for the process plant, with the project financing well underway.

We believe that the Company is better positioned at the end of 2012 than it was at the end of 2011, based on its operational run rate and streamlined organization. The status of development and execution of our new projects will drive our future growth, adding substantial value for all stakeholders."

Production and Cash Costs

The Company's production and cash costs for the three and twelve months ended December 31, 2012 are summarized in the table below:

	For the three months ended December 31, 2012			For the year ended December 31, 2012
	Oz Produced	Cash Costs1		Oz Produced	Cash Costs1
San Andres	11,936	$	1,242	59,751	$	1,015
Sao Francisco	29,368		1,218	80,357		1,528
Sao Vicente	8,952		1,092	33,155		1,537
Total / Average	50,256	$	1,201	173,263	$	1,353

Gold production at San Andres in the fourth quarter 2012 decreased 10% over the comparable period due to lower feed grade and recoveries.

Average cash cost per oz of gold produced¹ in the fourth quarter of 2012 was 12% higher than the fourth quarter of 2011. The increased cash cost per oz of gold produced was a result of lower oz produced.

Gold production at Sao Francisco in the fourth quarter of 2012 was 67% higher than the fourth quarter of 2011 primarily due to the higher plant feed.

Average cash cost per oz of gold produced in the fourth quarter of 2012 was 23% lower than the fourth quarter of 2011. The decreased average cash cost per oz of gold produced was primarily a result of focusing mining in the higher grade south end of the Sao Francisco pit to provide a large sump that would allow continued mining of the pit base during rainy season. The higher grade in the base of the pit has confirmed the model predictions of increased grade in the south end and will allow the mine to optimise the short term model reliability.

At Sao Vicente, 32% less gold oz were produced during the quarter ended December 31, 2012 compared to the quarter ended December 31, 2011 due to lower grades and the unexpected failure of the primary crusher at Sao Vicente during the third quarter. A rented crusher was utilized to mitigate this failure. The original primary crusher was replaced at the end of December 2012 and is working well with high availability.

The average cash cost per oz of gold produced¹ in the fourth quarter of 2012 was 8% higher than the average cash cost in the fourth quarter of 2011. The increase in the average cash cost per oz produced over the comparable period in 2011 was due to the lower grade processed.

Copper concentrate produced decreased by 14% in the fourth quarter 2012 when compared to the fourth quarter of 2011.

Average cash cost per payable pound of copper produced¹ for the fourth quarter of 2012 increased 134% compared to the fourth quarter of 2011. Average cash cost per payable pound of copper produced¹ increased to $5.42 from the third quarter of 2012 of $4.48 per payable pound of copper due to low production volumes and excess penalties and charges related to elevated arsenic levels. The impact on the fourth quarter of 2012's average cash cost¹ as a result of arsenic related charges and penalties is estimated to be $1.21 per payable pound of copper against the third quarter of 2012 of $1.14 per payable pound of copper.

Brazilian Mines - Value Maximization

The Company has been investigating multiple options to maximize the disposal and closure value of the assets of the Sao Francisco and Sao Vicente mines, including selling the plant and equipment and utilizing key members of their operating teams in other group locations.

Revenues and Cost of Goods Sold

Revenue for the three months ended December 31, 2012 and 2011 was $86,404,000 and $85,750,000, respectively. The Company's revenue for the fourth quarter 2012 is comprised of sales of gold from the Company's gold mines of $81,469,000 and copper concentrate sales from Aranzazu of $4,935,000 compared to $75,468,000 from the gold mines and $10,282,000 from Aranzazu for the fourth quarter of 2011.

	For the three months ended December 31, 2012		For the three months ended December 31, 2011		For the year ended December 31, 2012		For the year ended December 31, 2011

Total ounces sold		47,586		46,105		164,952		165,836
Realized average gold price per ounce ("oz")	$	1,725	$	1,669	$	1,667	$	1,572
Gold sales revenues (in '000's) net of local sales taxes	$	81,469	$	75,468	$	270,445	$	257,147
Copper concentrate sales (in '000's)	$	4,935	$	10,282	$	36,967	$	31,293
Total net sales(in '000's)	$	86,404	$	85,750	$	307,412	$	288,440

The 8% increase in gold sales resulted from a 3% increase in oz sold and a 3% increase in the realized average gold price per oz. The 52% decrease in copper concentrate sales resulted from a 13% decrease in DMT sold and a 45% decrease in the average price realized per DMT. The average price realized per DMT decreased due to the impact of the arsenic penalties and charges.

For the three months ended December 31, 2012, the Company recorded total cost of goods sold of $89,027,000. Cost of gold sold of $76,453,000 or $1,607 per ounce consisted of cash costs of $58,309,000 or $1,225 per ounce and non-cash depletion and amortization charges of $18,144,000 or $382 per ounce.

Outlook and Strategy

Aura Minerals' future profitability, operating cash flows and financial position will be closely related to the prevailing prices of gold and copper. Key factors influencing the price of gold and copper include the supply of and demand for these commodities, the relative strength of currencies (particularly the U.S. dollar) and macroeconomic factors such as current and future expectations for inflation and interest rates. Management believes that the short-to-medium term economic environment is likely to remain supportive for both gold and copper prices but with continued volatility for both.

Other key factors influencing profitability and operating cash flows are production levels (impacted by grades, ore quantities, labour, plant and equipment availabilities, and process recoveries) and production and processing costs (impacted by production levels, prices and usage of key consumables, labour, inflation, and exchange rates).

Aura Minerals' production and cash cost per oz guidance for the 2013 year is as follows:

Gold Mines	Cash Cost per oz	2013 Production
San Andres	$1,000 - $1,150	60,000 - 65,000 oz
Sao Francisco	$1,100 - $1,250	78,000 - 88,000 oz
Sao Vicente	$ 950 - $1,100	28,000 - 32,000 oz
Tot	$1,050 - $1,200	166,000 - 185,000 oz

Aranzazu's production for 2013 is expected to be between 13,000,000 and 15,000,000 pounds of copper at a range of $3.10 to $3.60 average cash cost per payable pound of copper.

In the first quarter of 2013 and to the date of this press release, the indicators have been that the pro-rata guidance will be achieved at each operating mine.

For 2013, capital spending is expected to be $101 million. Of this amount, $53 million relates to growth and sustaining capital for existing mines - including $36 million on the Aranzazu expansion and roaster installation and $7 million on Phase V of the heap leach expansion and community expenditures at San Andres. The remaining $48 million relates to the development and initial construction of Serrote.

Non-GAAP Measures

This news release includes certain non-GAAP performance measures, in particular, the average cash cost of gold per oz, average cash cost per payable pound of copper and operating cash flow which are non-GAAP performance measures. These non-GAAP measures do not have any standardized meaning within IFRS and therefore may not be comparable to similar measures presented by other companies. The Company believes that these measures provide investors with additional information which is useful in evaluating the Company's performance and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Average cash costs per oz of gold or per payable pound of copper are presented as they represent an industry standard method of comparing certain costs on a per unit basis. Total cash costs of gold produced include on-site mining, processing and administration costs, off-site refining and royalty charges, reduced by silver by-product credits, but exclude amortization, reclamation, and exploration costs, as well as capital expenditures. Total cash costs of gold produced are divided by oz produced to arrive at per oz cash costs. Similarly, total cash costs of copper produced include the above costs, and are net of gold and silver by-products, but include offsite treatment and refining charges. Total cash costs of copper produced are divided by payable pounds of copper produced to arrive at per payable pound cash costs.

Operating cash flow is the term the Company uses to describe the cash that is generated from operations excluding depletion and amortization, stock based compensation, impairment charges and the effect of changes in working capital.
