— On-site average cash cost(1) per pound of payable copper produced, net
of gold and silver credits, of $2.32 and $2.82, respectively, for the
fourth quarter and full year 2011. With increasing levels of production
in each quarter of 2011, cash costs(1) decreased 33%, 23% and 8%,
respectively, in the second, third and fourth quarters over each of the
prior quarters;
— Loss for the fourth quarter and full year 2011 of $10.1 million or $0.04
per share and $41.8 million or $0.19 per share, respectively;
— Adjusted loss(1) for the fourth quarter of $6.8 million or $0.03 per
share and adjusted loss(1) for the year ended December 31, 2011 of $6.0
million or $0.03 per share, after adjusting for write-downs of
inventory, impairment charges, unrealized foreign exchange losses and
other non-recurring revenue and expense items;
— Ended the fourth quarter of 2011 with $22.5 million in cash and cash
equivalents and $5 million available under the $25 million revolving
credit facility (“Credit Facility”), and subsequent to year- end, the
Company is in negotiations to amend the Credit Facility, which would
include an extension of the maturity to June 30, 2014 and an increase to
the revolving credit available to $45 million;
— Announced new business plans for the Brazilian Mines on November 10,
2011, based on updated geological models for those mines. The new
business plans feature optimized mine plans and lives, with operations
at the Sao Vicente Mine and Sao Francisco mine extending through 2013
and 2015, respectively;
— After quarter end, established a gold hedge program covering a total of
80,000 ounces of gold between April 1, 2012 and June 30, 2014, using
zero-cost put/call collars with a floor price of $1,700/oz and an
average ceiling price of $1,812/oz;
— Updated the resource estimate on October 17, 2011 for the Aranzazu Mine,
increasing tonnes of measured and indicated resources at a 0.8% Cu cut-
off by 25%, as compared to the September 2010 resources estimate and
based on similar average copper, gold and silver grades. It should be
noted that the updated resource estimate was based on an amount of
drilling that did not reach the limit of the ore body, which is still
open along strike and at depth. As a result, a preliminary economic
assessment (“Aranzazu PEA”) study is underway based on evaluating an
expanded throughput rate of up to 5,000 tonnes per day (“tpd”);
— Continued work on the feasibility study (the “Serrote Feasibility
Study”) for the Serrote de Laje project (“Serrote Project”), which is
scheduled for completion in the third quarter of 2012; and
— Updated the resource and reserve estimates effective December 31, 2011
for the San Andres Mine, increasing tonnes of proven and probable
reserves from 32.22 million tonnes as at December 31, 2010 to 45.76
million tonnes, representing a 33% increase in contained gold ounces.

“Despite experiencing several operational challenges during 2011, we continue to make significant progress towards improving our operations and advancing our projects,” stated Jim Bannantine, President and CEO of Aura Minerals. “At the Aranzazu Mine, mill and equipment availability were increased by adding skilled maintenance personnel and bringing in an experienced maintenance manager as well as increasing training. Alternate feeder arrangements were made to improve the processing of fine wet ore, and an experienced mine manager was contracted. The result was a steady ramp-up in ore mined, head grades, process recoveries, and concentrate production, accompanied by significant decreases in costs in each quarter.
At the San Andres Mine, the Company has taken several mitigating steps to improve production, including replacing the primary crusher wobbler during the first quarter of 2012 with a vibrating grizzly screen ahead of the jaw crusher to improve plant operating time, throughput and efficiency. More importantly, in February 2012, a new mine contractor with a proven track record and a fleet of 40 tonne articulated trucks that can safely operate in wet weather conditions, was commissioned to take over the mining operations with the aim of improving all aspects of mining operations.
For the Sao Vicente and Sao Francisco Mines, our teams implemented the new mine plans, based on the new geological modeling, to optimize production and reduce strip ratios, and thereby reduce costs. The results are already showing at the Sao Vicente Mine with decreasing cash costs as compared to prior quarters. At the Sao Francisco Mine, the failure of the primary crusher main bearing and structural failure of the crusher feed bin resulted in the operation not having use of the primary crusher for 47 days, prevented us from realizing the benefits of the improved ore grades and lower strip ratios, but the crusher was rebuilt and re-installed in late-March 2012 and is now back in operation. We are now looking forward to getting this operation back on plan in the months ahead and becoming a significant generator of cash. In connection with the mine plans at the Brazilian mines, we implemented a gold hedging program in late February to take advantage of high gold prices at the time and secure cash flows at these operations. We have hedged 80,000 ounces of gold production through June 2014, using a series of zero-cost collars having a floor price of $1,700 per ounce and an average ceiling price of $1,812 per ounce.
With an improved outlook for cash generation this year from our asset portfolio, combined with lower capital expenditures than in past years, and the credit facility upsizing which we expect to close in April, we are better positioned for the next stages of the Company’s growth. This includes increasing the Aranzazu Mine throughput level to up to 5,000 tpd, subject to a positive Aranzazu PEA, with internal capital provided by the Brazilian mines over the next three years, and developing the Serrote Project to significantly increase the size of the Company, subject to a positive Serrote Feasibility Study.”

For the quarter and year ended December 31, 2011, the Company recorded cost of goods sold of $82.0 million and $264.2 million, respectively, including non-cash depletion and amortization charges of $18.7 million and $55.8 million for the three and twelve month periods then ended. Gross profit for the fourth quarter and year ended December 31, 2011 were $3.7 million and $24.2 million, respectively. These compare to a gross profit of $11.6 million and $25.4 million for the fourth quarter and year ended December 31, 2010, respectively.
Other expense items for the fourth quarter of 2011 include general and administrative expenses of $4.6 million and exploration expenses of $3.8 million. Other expense items for 2011 include general and administrative expenses of $25.5 million and exploration expenses of $13.2 million. General and administrative costs for the quarter and year included share-based compensation expense of $0.7 million and $7.3 million, respectively. Since year end 2011 management has taken steps to reduce general and administrative expenses by up to 20%.
Additionally, for the fourth quarter of 2011, the Company recorded finance costs of $1.1 million, interest and other expenses of $0.5 million, and other losses of $3.6 million. Loss before income taxes for the fourth quarter of 2011 was $9.8 million. For 2011, the Company recorded finance costs of $4.6 million, interest and other expenses of $0.3 million, and other losses of $0.4 million. Other 2011 income and expenses items include in a gain on the restructuring of certain contractual obligations of $17.0 million, which was recorded in the first quarter of the year, and an impairment charge of $38.5 million related to the assets and goodwill of the Sao Francisco and Sao Vicente Mines, which was recorded in the third quarter of the year. Loss before income taxes for 2011 was $41.3 million.
For the fourth quarter and 2011 year, the Company recorded a net loss of $10.1 million or $0.04 per share and $41.8 million or $0.19 per share, respectively. Adjusted loss(1) for the fourth quarter was $6.8 million or $0.03 per share and adjusted loss(1) for the year ended December 31, 2011 of $6.0 million or $0.03 per share.
Liquidity and Capital Resources
As at December 31, 2011, the Company’s working capital was $83.8 million, including cash and cash equivalents of $22.5 million. In addition, the Company had $5 million available under its $25 million Credit Facility. During the year ended December 31, 2011, working capital increased by $33.2 million. The working capital increase is primarily attributable to the restructuring of debt completed in the first quarter of 2011 and the inventory build-up at the Sao Francisco Mine following the resumption of normal operations early in the second quarter.
The Company is in negotiations to amend the Credit Facility, which would include an extension of its maturity to June 30, 2014 and an increase in the revolving credit available to $45.0 million. Closing of the amended credit facility is expected to be in April 2012.

Gold production at the San Andres Mine in the fourth quarter and 2011 year, of 13,201 ounces and 60,870 ounces of gold, respectively, was down 32% and 14% from the fourth quarter and full year 2010. Lower gold production during the quarter and year is primarily attributable to the continued impact of processing lower-recovery mixed ore that had a higher component of clay alteration, which typically results in lower ore movement from the mine, and downtime associated with the processing of wet ore and cleaning of chutes, as well as, poor contractor performance. The Company has taken several mitigating steps to improve production, including replacing the primary crusher wobbler during the first quarter of 2012 with a vibrating grizzly screen ahead of the jaw crusher to improve plant operating time, throughput and efficiency. Starting in February 2012, a new mine contractor with a proven track record, has been commissioned to take over the mining operations with the aim of improving mining operation reliability and productivity and safety. During the transition period, the previous contractor will remain to ensure production is not impacted. The new contractor has a fleet of 40 tonne articulated trucks that can safely operate in wet weather conditions to ensure productivity goals can be achieved.
Operating cash costs(1) of $1,110 per ounce of gold produced in the fourth quarter of 2011 compare to $562 per ounce in the fourth quarter of 2010. For the full year, 2011 cash costs(1) of $837 per ounce of gold produced compare to $589 per ounce in 2010. Increased cash costs(1) over the fourth quarter and full year 2010 are primarily a result of significantly higher strip ratios and lower recovery rates from treating mixed ore, both of which impacted gold production, and higher unit operating costs.
As stated above, the Company has updated the mineral resource and reserve estimates for the San Andres Mine as at December 31, 2011 (the “December 2011 Resource and Reserve Estimate”).
The table below presents the updated mineral resource estimate of 98.94 million tonnes of measured and indicated mineral resources at an average grade of approximately 0.51 g/t gold and inferred mineral resource of 1.9 million tonnes at an average grade of 0.51 g/t gold, using a long term US$1,500 per ounce gold price and a cut-off grade of 0.28 g/t gold for oxide ore and 0.37 g/t gold for mixed ore. The resource pit shell optimization did not consider any sulphide material.

Full year 2010 results in the table below include operating information only following the mine’s acquisition on May 1, 2010. Further, both years are impacted by the dedicated waste stripping program which was undertaken from early December 2010 through early April 2011. During this period, crushing and processing operations were suspended, as the Company focused solely on waste stripping and upgrades to the crushing and gravity circuits. Total waste material moved as part of the stripping program was approximately 7.8 million tonnes.
Gold production in the fourth quarter of 2011 was 17,555 ounces, an increase of 36% over the same quarter in 2010. Similarly, gold production in the full year 2011 was 56,286 ounces, an increase of 55% over 2010 gold production. As stated above, 2010 production includes production from May 1, 2010 to year end, whereas 2011 production included 7,188 ounces leached during the stripping campaign and stacked in 2010, as well as production following the completion of the stripping program.
Fourth quarter 2011 production was impacted by a failure of the main shaft bearing in the jaw of the primary crusher in late-November, which was down for approximately two weeks before a rental crusher was installed. Although smaller than the primary crusher, the rental crusher made up a sizable percentage of the otherwise lost throughput. Production in the first quarter of 2012 has also been impacted by the jaw crusher bearing failure as well as a structural failure of the primary crusher feed bin in early February, which resulted in the operation not having use of the primary crusher for 47 days. The structural issues were rectified and the crusher was sent for repairs and scheduled rebuild and was re- installed at site in late-March 2012 and is now back in operation. During this period, overall throughput rates were reduced by an estimated 35%.

The Sao Vicente Mine produced 13,107 gold ounces in the fourth quarter of 2011, an increase of approximately 9% over production recorded in the fourth quarter of 2010. Production in 2011 was 43,003 gold ounces, an increase of approximately 41% over 2010, for which results are shown only from May 1, 2010. Increased production was due primarily to higher head grades of the ore processed over 2010 and slightly higher recoveries. The increase in ore grade in 2011 is the result of accessing higher grade ore located in the bottom of the pit, which was generally inaccessible late in 2010 through early in 2011 due to dewatering issues associated with the excessive rainfall.
Despite a 20% year-over-year average cash costs(1) increase at the Sao Vicente Mine, from $1,029 to $1,235 per ounce, quarterly cash costs(1) have decreased in each quarter. The average cash cost(1) per ounce produced in the fourth quarter of 2011 was $1,015 compared to $1,077 per ounce in the fourth quarter of 2010. The decrease in fourth quarter costs is a result of higher head grades, as described above, increased recoveries, and a significantly lower strip ratio, offset by in-country inflation and general cost escalation.

Following the restart of operations, the Aranzazu Mine was adversely impacted by a number of operational issues. The processing of a more highly oxidized ore than planned in 2011 also impacted concentrate grades in the year. The operational issues were overcome and copper recoveries increased quarter-by-quarter as the proportion of oxidized ore decreased. The continued ramp-up throughout 2011 saw steady increases in open pit and underground ore mined, ore grades and recoveries. This resulted in significant quarter-over-quarter increases in concentrate and metal production. Despite a 20% and 25% increase in concentrate and metal production over the previous quarter, mill throughput in the fourth quarter was still impacted by lower than expected mill and equipment availability due in part to a water shortage caused by water line scaling and some limited power supply failures. Water line clearing was completed by March 2012 and improvements in power supply were also rectified shortly after year end; however, these did not have material impacts in first quarter 2012 production levels.
Cash costs(1) per payable pound of copper for the fourth quarter and full year 2011 were $2.32 and $2.82, respectively. Cash costs(1) per payable pound of copper have steadily decreased quarter by quarter as production continues to increase, recoveries improve and the Aranzazu Mine moves towards design levels for throughput and concentrate production.
Subsequent to year-end, the Aranzazu Mine experienced unusual levels of arsenic in its concentrate production. These levels are outside contract specifications and will likely result in increased treatment charges from the Company’s off-take customer. The Company is investigating the source of the arsenic, monitoring its levels and is working with its customer to address the issue. The magnitude of any increased treatment charges and the duration of the elevated arsenic levels in the Aranzazu Mine’s production are currently being reviewed.
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. The Company’s future operating and financing cash flows are expected to fund internal growth and overall expansion of our projects. 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 gold and copper prices with continued volatility in both.
The Company believes that 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 – which are impacted by production levels, prices and usage of key consumables, labour, inflation, and exchange rates.
Aura Minerals’ full year 2012 gold production and average cash cost(1) guidance per mine, is as follows:
Gold Mines – Production Estimates
—————————————————————————-
San Andres Mine $1,000 – $1,100 60,000 – 65,000 oz
Sao Francisco Mine $1,500 – $1,700(i) 70,000 – 80,000 oz
Sao Vicente Mine $1,100 – $1,200 35,000 – 40,000 oz
—————————————————————————-
Total $1,250 to $1,400 165,000 – 185,000 oz
—————————————————————————-
—————————————————————————-
(i) Full year 2012 cost estimate includes first quarter impact of failure in
primary jaw crusher and structural failure of primary crusher feed bin.
Operating cash costs(1) per ounce for the San Andres Mine in the first half of 2012 are expected to be comparable to cash costs(1) recorded in the fourth quarter of 2011, based on similar ore grades, waste-to- ore ratios and process recoveries experienced during the quarter. In the second half of 2012, the mining of lower percentage of mixed ore and expected improvements in the productivity of the recently replaced mining contractor are expected to enhance overall mine performance and lower unit production costs.
Operating cash costs(1) per ounce for the Sao Francisco Mine have been adversely affected since late- November by the failure of the main shaft bearing of the primary jaw crusher and by the structural failure of the primary crusher feed bin in early February, which resulted in the operation not having use of the primary crusher for 47 days. As a result of these failures and other unrelated issues, overall throughput rates were reduced by an estimated 35% during this period, causing production to decrease and costs to increase. The structural issues were rectified and the crusher was rebuilt and then re-installed at the Sao Francisco Mine site in late-March 2012 and is currently in operation. The one-time impact of the failed jaw crusher bearing and the structural failure of the feed bin in the first quarter of 2012, combined with the mining and processing of lower grade ore material during the first and second quarters of 2012, will adversely impact production and increase cash costs(1) in the first half of 2012. However, in accordance with the new business and mine plan for this operation, cash costs(1) are expected to decrease in the second half of 2012 and further decrease in subsequent years as progressively higher grade ore material is mined as the pit deepens, and as strip ratios are reduced.
Operating cash costs(1) per ounce for the Sao Vicente Mine for 2012 are expected to be similar to those experienced in 2011, based on the new mine and business plan for the operation, which includes: a reduction in the strip ratios; slight increases in the average mine grades; and reduced mining and haulage costs associated with considerably less waste.
The Company’s 2012 production guidance for the Aranzazu Mine is summarized in the table below:
Aranzazu Mine – Production Estimates
—————————————————————————-
Copper 13,000,000 – 14,000,000 lbs
Gold 7,500 – 8,500 oz
Silver 145,000 – 155,000 oz
—————————————————————————-
The Company’s 2012 cash costs(1) for the Aranzazu Mine are forecast to be $1.75 to $2.00 per pound of payable copper net of gold and silver by-products based on assumed gold and silver prices of $1,650 per ounce and $32 per ounce, respectively.
Total capital expenditure guidance for the fiscal year 2012 is approximately $28 million, with $19 million relating to growth and sustaining projects and $9 million relating to the continued mine development at the Aranzazu Mine. Exploration expenses are forecast to be approximately $9 million in 2012, including costs associated with the completion of the Serrote Feasibility Study and the Aranzazu PEA as well as resource definition and expansion drilling at the San Andres Mine. Capital and exploration expenditures for 2012 are expected to be funded from operating cash flows.
(1) See cautionary note regarding non-GAAP measures.
The Company’s primary strategic focus for 2012 is to unlock the value of its portfolio of producing mines by:
— focusing on improving operational efficiencies at the San Andres Mine to
reduce cash costs and conducting an in-fill drilling program to
potentially expand resources and reserves;
— maintaining steady state operations at the Aranzazu Mine with mill
throughput of 2,600 tpd and completing the Aranzazu PEA to potentially
increase mill throughput up to 5,000 tpd; and
— achieving, sustaining and maximizing cash flows from the Brazilian Mines
by executing the new life of mine plans with reduced strip ratios and
improved ore grades.
Longer term, the Company’s organic growth plans include:
— ensuring the San Andres Mine provides continuous cash flows for the
foreseeable future;
— increasing the Aranzazu Mine throughput levels up to 5,000 tpd with
internal capital provided by the Brazilian Mines over the next three
years, to be confirmed by the Aranzazu PEA; and
— developing the Serrote Project to significantly increase the size of the
Company, subject to completion of the Serrote Feasibility Study.
