03/28/2012

TORONTO, ONTARIO--(Marketwire - March 28, 2012) -

(Please note that all dollar amounts in this news release are expressed in U.S. dollars. Refer to the 2011 year-end management discussion and analysis (MD&A) and audited financial statements for more information.)

Primero Mining Corp. ("Primero" or the "Company") (TSX:P)(NYSE:PPP) today reported financial results for the fourth quarter and year ended December 31, 2011. The Company reported 2011 net earnings of $67.8 million ($0.77 per share) with adjusted net earnings of $28.3 million ($0.32 per share). Operating cash flows(3) were $80.2 million ($0.91 per share).

"2011 marked Primero's first full year as a gold and silver producer," said Mr. Joseph F. Conway , President and Chief Executive Officer. "We remained focused on optimizing San Dimas as a platform from which to expand our future production. We generated positive earnings and cash flow that enabled us to reinvest in our operation, pay down a large portion of our debt and still build our cash position considerably. Our objective for 2012 is to grow our production, reserves, earnings and cash flow. We will also remain focused on evaluating strategic growth opportunities as we assess the expansion opportunity."

Fourth Quarter and Full Year 2011 Highlights:

--  Strong Earnings and Cash Flow: Annual 2011 earnings of $67.8 million
    ($0.77 per share) with adjusted net earnings of $28.3 million ($0.32 per
    share) and operating cash flow before working capital changes of $80.2
    million ($0.91 per share);

--  Steady Production: Fourth quarter production of 23,100 gold equivalent
    ounces(1) contributed to annual production of 102,220 gold equivalent
    ounces; up slightly from 2010 San Dimas full year production;

--  Excellent Cost Control: Full year total cash costs(2) of $640 per gold
    equivalent ounce, or $384 per gold ounce on a by-product basis(2). Mine-
    site costs per tonne remained 1% below budget;

--  Strengthened Balance Sheet: Grew cash position to $80.8 million at
    December 31, 2011, while paying down a substantial portion of the
    Company's debt;

--  Improved Liquidity and Expanded Shareholder Base: Primero listed on the
    NYSE, under the symbol PPP during 2011, doubling daily trading volumes;

--  Advanced Tax Ruling in Process ("APA"): If successful, would result in
    paying taxes based on actual realized prices rather than spot prices.

Net Earnings Reflect Tax Provision Based on Realized Silver Revenue

Revenues in the fourth quarter of 2011 were $35.6 million compared to $41.4 million in the fourth quarter 2010 as a result of selling 31% less gold equivalent ounces, partially offset by a higher gold price. The Company sold 18,490 ounces of gold at an average realized price of $1,679 per ounce and 1.11 million ounces of silver at an average realized price of $4.08 per ounce in accordance with the silver purchase agreement(5). Gold sales in the fourth quarter of 2010 included approximately 6,000 ounces that were produced by Goldcorp Inc. and were in transit to the refinery at the time of acquisition of the San Dimas Mine.

Operating cash flow before working capital changes increased in the fourth quarter to $14.6 million ($0.17 per share), compared to $13.4 million ($0.15 per share) in the fourth quarter of 2010.

The Company earned net income of $36.8 million ($0.42 per share) in the fourth quarter of 2011, compared with net income of $6.9 million ($0.08 per share) in the fourth quarter of 2010 due mainly to the impact of the APA filing and the resultant recovery of income taxes retroactive to the date of acquisition of the San Dimas Mine.

Adjusted net income for the fourth quarter was $4.7 million ($0.05 per share), compared to an adjusted net income of $10.2 million ($0.12 per share) in the fourth quarter of 2010. Adjusted net income for the fourth quarter of 2011 primarily excludes the benefit of the APA application for the period August 6, 2010 to September 30, 2011. Non-cash share-based payment expense of $1.5 million (2010 - $1.5 million), or $0.02 per share (2010 - $0.02 per share) has not been excluded in calculating adjusted net earnings.

Revenue was $156.5 million for 2011 compared to $60.3 million in 2010. Revenue in 2010 was generated between August 6, 2010 and December 31, 2010, the period when the Company owned the San Dimas Mine. During 2011, the Company sold 77,490 ounces of gold at an average price of $1,561 per ounce and 4.6 million ounces of silver at an average price of $7.69 per ounce.

Operating cash flow before working capital changes increased to $80.2 million ($0.91 per share) in 2011, from $12.2 million ($0.33 per share) in 2010.

The Company earned net income of $67.8 million ($0.77 per share) in 2011 compared with a net loss of $31.5 million ($0.85 per share) in 2010. The $99.3 million increase in net income in 2011 was mainly due to a $50.9 million increase in earnings from mine operations (full year of operations, higher gold prices and first spot silver sales in 2011); $39.9 million increase in other income net of other expense (Northgate net break fee in 2011, San Dimas transaction costs and legal settlement in 2010); $20.6 million lower tax expense in 2011 (benefit of filing APA application), partly offset by $7.9 million higher general and administrative expenses and $4.3 million more finance and other types of expense in 2011.

Adjusted net income for 2011 was $28.3 million ($0.32 per share) compared with adjusted net income of $5.1 million ($0.14 per share) in 2010. The 2011 adjusted net income primarily excludes one-time gains related to the Northgate transaction, a reduction in taxes due to a foreign exchange loss on an intercompany loan novated during the year, realized foreign exchange gains on the repayment of the VAT related to the purchase of San Dimas from the Mexican government and the benefit of the APA application for the period August 6, 2010 to December 31, 2010. Non-cash share-based payment expense of $8.1 million (2010 - $8.6 million), or $0.09 per share (2010 - $0.23 per share), has not been excluded in calculating adjusted net income in 2011.

Increased Throughput Results in Steady Production

Primero produced 23,100 gold equivalent ounces during the fourth quarter of 2011. This resulted in annual 2011 production of 102,220 gold equivalent ounces, slightly above the 2010 San Dimas full year production and within the revised guidance range.

The Company produced 20,190 ounces of gold and 1.20 million ounces of silver in the fourth quarter 2011, 5% and 1% lower, respectively, than the fourth quarter 2010, due to lower grades (8% lower for gold and 6% lower for silver) partially offset by 4% higher throughput. This resulted in annual 2011 production of 79,564 ounces of gold and 4.6 million ounces of silver, 7% less and 2% more, respectively, than 2010.

The reduction in gold production was primarily due to a 14% decrease in grades in the main production stopes. In 2011, most of the ore came from the Central Block where grades in the Roberta and Robertita veins were below expectations. The impact of the decline in grade was partially offset by an 8% increase in throughput from an average of 1,800 tonnes per day in 2010 to 1,950 tonnes per day in 2011. The Company has focused on increasing throughput and expects to increase it by a further 8% in 2012 to an average of 2,050 tonnes per day.

The Company was successful at controlling costs, keeping costs per tonne for 2011 to within 1% of budget. Total cash costs were $719 per gold equivalent ounce, or $580 per gold ounce on a by-product basis for the fourth quarter of 2011; and $640 per gold equivalent ounce, or $384 per gold ounce on a by-product basis for the full year 2011.

Cash Position Remains Strong

Cash decreased to $80.8 million at December 31, 2011 from the September 30, 2011 balance of $107.2 million, as the Company repaid $30 million of its convertible debt during the quarter. During 2011 the Company illustrated its ability to internally fund future growth, while making substantial debt repayments and increasing its cash position considerably from the December 31, 2010 balance of $58.3 million.

Capital expenditures during the fourth quarter were $8.7 million resulting in full year 2011 capital expenditures of $29.8 million. In 2012, capital expenditures are again expected to total approximately $30 million. With its cash balance and anticipated cash flows, Primero management believe it is fully funded to expand production at San Dimas while remaining well positioned to take advantage of strategic growth opportunities.

2011 Mineral Resources and Mineral Reserves

The Company today announced updated Mineral Resources and Mineral Reserves for its San Dimas mine.

"In early 2012, the Company elected to review its Mineral Resource estimation methodology," stated Mr. Joseph F. Conway , President and Chief Executive Officer. "This change has improved our geological understanding and, as a result, the predictability of our near term operating results at San Dimas. We remain committed to expanding production and believe the new approach will enable Primero to more accurately mine plan for the expansion decision slated for the third quarter of this year. While the new Resource estimation has resulted in a reduction in and reclassification of Resources and Reserves, our improved understanding and the advancements in underground development should position the Company to convert Resources and exploration potential into Reserves in the near term. We remain confident of the mineral potential at San Dimas, particularly given historical production of over 11 million ounces of gold and the presence of numerous exploration targets.

"We are also very pleased to announce today a new high-grade discovery in the Sinaloa Graben block that is within 140 metres of existing tunnel development and we expect to access this area before the end of 2012. This discovery supports the position that Inferred Resources estimated with the historical estimation method remain high-probability exploration targets."

For further details please refer to the Company's separate news release of today: "Primero Reports 2011 Reserves and Resources and Announces New High-Grade Discovery," which can be found at www.primeromining.com.

Expansion Decision Expected During Third Quarter

Recent advances in underground development have provided access to key strategic locations within the prolific central corridor of the Sinaloa Graben. The Company expects to continue to accelerate development in the Sinaloa Graben during 2012 and with continued exploration success, such as the new Victoria vein, increase working faces to support a mill expansion.

During 2012 and 2013 the Company will continue to focus on maximizing the throughput of the mill at 2,050 tonnes per day or better while it develops stopes with higher grade ore. The Company has also completed preliminary engineering to assess different mill expansion scenarios; both 2,500 tonnes per day and 3,000 tonnes per day scenarios have been examined. Currently the San Dimas mill is principally limited by its grinding capacity which can be resolved by installing the third ball mill that is already on-site. With the installation of this ball mill and limited optimization of current crushing and processing facilities, the overall mill capacity could be expanded to up to 3,000 tonnes per day for less than an estimated $15 million.

With completion of the 2011 Mineral Resources and Reserves estimation, the Company will now commence detailed engineering of both mill expansion scenarios. San Dimas could to be producing at between 2,500 tonnes per day and 3,000 tonnes per day by mid-2014 with continued positive exploration results from the Sinaloa Graben combined with productivity enhancements. The Company expects to make an expansion decision during the third quarter of 2012.

As a first step towards expanding San Dimas, the Company has recently completed a comprehensive mapping of its operating processes with the assistance of an external firm specialized in mining process improvement. Results of the analysis show significant opportunity to enhance overall mine productivity in excess of 20%. Implementation of the process improvement program will begin in early April and Management expects it will result in a 10% to 15% productivity improvement in 2012.

Commitment to Corporate Responsibility and Improving Health and Safety Record

Primero is committed to embedding corporate responsibility into its daily activities. The Company's goal is to continuously improve workplace health and safety, as well as its environmental performance, and to share the benefits of mining with local communities.

Primero was faced with the tragedy of a fatality during 2011 and the Company reinforced its commitment to health and safety at San Dimas throughout the year. The mine ultimately achieved a reduction in the total accident frequency index during 2011, the sixth consecutive annual reduction at San Dimas.

Primero was proud to be recognized by the Mexican Center for Philanthropy (CEMEFI) and the Alliance for Corporate Social Responsibility (AliaRSE) with the Empresa Socialmente Responsable (Socially Responsible Business Distinction) distinction.

This release should be read in conjunction with Primero's audited year-end 2011 financial statements and MD&A report on the Company's website, www.primeromining.com, in the "Financial Reports" section under "Investors," or on the SEDAR website at www.sedar.com.

(1)  "Gold equivalent ounces" include silver ounces produced, and converted
     to a gold equivalent based on a ratio of the average commodity prices
     realized for each period. The ratio for the fourth quarter was 412:1
     based on the average realized prices of $1,679 per ounce of gold and
     $4.08 per ounce of silver. The ratio for full year 2011 was 203:1 based
     on the average realized prices of $1,561 per ounce of gold and $7.69
     per ounce of silver. The ratio used for the 2012 guidance projection is
     170:1 based on estimated average prices of $1,600 per ounce of gold and
     $9.41 per ounce of silver.

(2)  Total cash costs per gold equivalent ounce and total cash costs on a
     by-product basis are non-GAAP measures. Total cash costs per gold
     equivalent ounce is defined as cost of production (including refining
     costs) divided by the total number of gold equivalent ounces produced.
     Total cash costs on a by-product basis are calculated by deducting the
     by-product silver credits from operating costs. The Company reports
     total cash costs on a production basis. In the gold mining industry,
     these are common performance measures but do not have any standardized
     meaning, and are non-GAAP measures. The Company follows the
     recommendations of the Gold Institute standard. The Company believes
     that, in addition to conventional measures, prepared in accordance with
     GAAP, certain investors use this information to evaluate the Company's
     performance and ability to generate cash flow. Accordingly, it is
     intended to provide additional information and should not be considered
     in isolation or as a substitute for measures of performance prepared in
     accordance with GAAP. See the 2011 year-end MD&A for a reconciliation
     of total cash costs to reported operating expenses (the nearest GAAP
     measure).

(3)  "Operating cash flow" is operating cash flow before working capital
     changes. This and operating cash flows before working capital changes
     per share are non-GAAP measures which the Company believes provides a
     better indicator of the Company's ability to generate cash flow from
     its mining operations. See the 2010 year-end MD&A for a reconciliation
     of operating cash flows to GAAP.

(4)  Adjusted net income (loss) and adjusted net income (loss) per share are
     non-GAAP measures. Neither of these non-GAAP performance measures has
     any standardized meaning and is therefore unlikely to be comparable to
     other measures presented by other issuers. The Company believes that,
     in addition to conventional measures prepared in accordance with GAAP,
     the Company and certain investors use this information to evaluate the
     Company's performance. Accordingly, it is intended to provide
     additional information and should not be considered in isolation or as
     a substitute for measures of performance prepared in accordance with
     GAAP. Refer to the 2011 year-end MD&A for a reconciliation of adjusted
     net loss to reported net loss.

(5)  According to the silver purchase agreement between the Company and
     Silver Wheaton Corp., until August 6, 2014 Primero will deliver to
     Silver Wheaton a per annum amount equal to the first 3.5 million ounces
     of silver produced at San Dimas and 50% of any excess at $4.08 per
     ounce (increasing by 1% per year). Thereafter Primero will deliver to
     Silver Wheaton a per annum amount equal to the first 6.0 million ounces
     of silver produced at San Dimas and 50% of any excess at $4.20 per
     ounce (increasing by 1% per year). The Company will receive silver spot
     prices only after the annual threshold amount has been delivered.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF INDICATED AND INFERRED RESOURCES AND RESERVES ESTIMATES

This news release has been prepared in accordance with the requirements of Canadian provincial securities laws which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all mineral reserve and resource estimates included in this news release have been prepared in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum classification systems. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the requirements of the United States Securities and Exchange Commission (the "SEC"), and reserve and resource estimates disclosed in this news release may not be comparable to similar information disclosed by U.S. companies.

The mineral reserve estimates in this news release have been calculated in accordance with NI 43-101, as required by Canadian securities regulatory authorities. For United States reporting purposes, SEC Industry Guide 7 under the United States Securities Exchange Act of 1934, as amended, as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. As a result, the definition of "probable reserves" used in NI 43-101 differs from the definition in the SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, mineral reserve estimates contained in this news release may not qualify as "reserves" under SEC standards.

In addition, this news release uses the terms "indicated resources" and "inferred resources" to comply with the reporting standards in Canada. The Company advises United States investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves. Further, "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the "inferred resources" exist. In accordance with Canadian securities laws, estimates of "inferred resources" cannot form the basis of feasibility or other economic studies. It cannot be assumed that all or any part of "indicated resources" or "inferred resources" will ever be upgraded to a higher category or are economically or legally mineable. In addition, disclosure of "contained ounces" is permitted disclosure under Canadian securities laws; however, the SEC only permits issuers to report mineralization as in place tonnage and grade without reference to unit measures.

NI 43-101 also permits the inclusion of disclosure regarding the potential quantity and grade, expressed as ranges, of a target for further exploration provided that the disclosure (i) states with equal prominence that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resources, and (ii) states the basis on which the disclosed potential quantity and grade has been determined. Disclosure regarding exploration potential has been included in this news release. United States investors are cautioned that disclosure of such exploration potential is conceptual in nature by definition and there is no assurance that exploration will result in any category of NI 43-101 mineral resources being identified.

(1)  The San Dimas Mine was acquired by Primero from Goldcorp Inc. on August
     6, 2010. The comparative operating data was derived from records
     maintained by Goldcorp Inc.

(2)  Due to a silver purchase agreement originally entered into in 2004, all
     silver produced prior to August 6, 2010 was sold to Silver Wheaton at a
     fixed price. As a result of restructuring the silver purchase agreement
     on August 6, 2010, Primero will be able to sell some silver production
     at spot prices, subject to minimum threshold amounts being met(5).

(3)  Total cash costs per gold ounce on a gold equivalent and by-product
     basis are non-GAAP financial measures. Refer to "Non-GAAP measure -
     Total cash costs per gold ounce calculation" in the Company's year end
     2011 MD&A for a reconciliation to operating expenses. The by-product
     cash costs presented in this table prior to August 6, 2010 are based on
     internal financial records of the San Dimas operations and are
     calculated on a production basis and do not contain certain inter-
     company transactions that were reversed for Goldcorp's consolidated
     reporting.
