Primero Achieves 2012 Guidance and Provides 2013 Outlook

Primero Achieves 2012 Guidance and Provides 2013 Outlook 
TORONTO, ONTARIO -- (Marketwire) -- 01/23/13 --  
(Please note that all dollar amounts in this news release are
expressed in Canadian dollars unless otherwise indicated.)  
Primero Mining Corp. ("Primero" or the "Company") (TSX:P)(NYSE:PPP)
today announced production and estimated cash costs for 2012 and
provided production and cash cost guidance for 2013 with a three year
outlook.  
Highlights: 


 
--  Strong fourth quarter production of 26,300 gold equivalent ounces(1)
    resulted in annual 2012 production of 111,130 gold equivalent ounces, 9%
    higher than 2011 and within the Company's increased guidance range(2); 
    
--  Cash costs(3), (4) for full year 2012 are estimated at $636 per gold
    equivalent ounce, or $365 per gold ounce after by-product credits,
    within the Company's guidance range; compared to $640 per gold
    equivalent ounce, or $384 per gold ounce on a by-product basis in 2011; 
    
--  Production is expected to increase again in 2013 by up to 17% to between
    120,000 and 130,000 gold equivalent ounces; 
    
--  Three-year plan forecasts at least an 80% increase in production from
    2012 to over 200,000 gold equivalent ounces, including production from
    Cerro Del Gallo, by the end of 2015(5). 

 
"Primero had an excellent year in 2012," stated Joseph F. Conway,
President and C.E.O. "We demonstrated that the San Dimas mine has
significant geological potential and we announced an expansion which
will boost production by at least 40% within the next two years. We
also improved our tax position - substantially increasing our annual
cash flow. In December we announced the pending acquisition of the
Cerro Del Gallo development project in Mexico, which will increase
our medium-term production to over 250,000 gold equivalent ounces(5)
per year and more than triples our resource base. All of these
activities translated into a superior share price performance.
Primero's share value increased by 97% in 2012 compared against
industry equity benchmarks which were all negative. We intend to
continue to deliver positive results for all our stakeholders in 2013
and beyond." 
Strong Fourth Quarter Production Closes a Successful Year for Primero 
Primero produced 
26,300 gold equivalent ounces during the fourth
quarter of 2012. This resulted in annual 2012 production of 111,130
gold equivalent ounces, within the Company's increased guidance range
of 110,000 to 120,000 gold equivalent ounces.   
The Company produced 23,140 ounces of gold and 1.31 million ounces of
silver(6) in the fourth quarter 2012, 15% and 10% higher,
respectively, than the fourth quarter 2011, due mainly to higher
throughput. This resulted in the Company producing 87,899 ounces of
gold and 5.13 million ounces of silver in full year 2012, 10% and 12%
higher than 2011 respectively.  
Production at San Dimas in 2012 was higher than 2011 primarily as a
result of mining more ore at similar grades. Throughput in 2012
increased by approximately 9% over 2011, averaging 1,976 tonnes per
day ("TPD") (based on 365 day availability), mainly as a result of
the Company's mining optimization program that was initiated
mid-year. The optimization program has been successful at reducing
process variation, increasing throughput and has also improved mining
dilution rates observed.  
The Company was also successful at controlling costs, slightly
lowering 2012 costs per tonne compared to 2011. Fourth quarter cash
costs are expected to be $677 per gold equivalent ounce, or $535 per
gold ounce on a by-product basis. Total cash costs for the full year
2012 are expected to be $636 per gold equivalent ounce, or $365 per
gold ounce on a by-product basis.   
As part of the Company's optimization program it began testing
long-hole mining during the third quarter of 2012. By the end of 2012
Primero was operating two long-hole drills to test the mining method
in several of the San Dimas veins with varying widths and dip.   
Results were very encouraging and as a result the Company has
included long-hole mining as part of the 2013 mine plan. The main
conclusions of the long-hole testing at San Dimas were:  


 
--  It is possible to drill/blast even the narrow San Dimas vein systems
    while maintaining overall dilution of 20-30%. This compares favourably
    to the use of current jumbo drills at 70-100% dilution. 
    
--  Use of long-hole mining is expected to reduce total development required
    for operation. 
    
--  Management estimates it can include long-hole mining for up to 30% of
    total mining at San Dimas, which could ultimately represent a reduction
    of 15% of mining unit costs and a reduction of overall mining dilution
    to approximately 40% compared to the 2011 reserve estimate of 58%. 
    
--  Implementation of long-hole mining (planning/development/mining
    sequences) will require a transition period of approximately one year at
    San Dimas. 

 
Robust Outlook for 2013 
In 2013 Primero expects to increase production to between 120,000 and
130,000 gold equivalent ounces, up to 17% higher than 2012, based on
higher throughput at slightly higher grades. Production is expected
to ramp-up at the end of the first quarter when the current maximum
milling capacity of 2,150 TPD is achieved. 
Cash costs for 2013 are expected to be in the range of $620 to $640
per gold equivalent ounce or between $280 and $300 per gold ounce on
a by-product basis, similar to or below 2012 cash costs. Primero's
2013 outlook is summarized in the following table:  


 
                                                                            
----------------------------------------------------------------------------
                                                                Outlook 2013
----------------------------------------------------------------------------
Attributable gold equivalent production(1) (gold             120,000-130,000
 equivalent ounces)                                                         
Gold production (ounces)                                      90,000-100,000
Silver production(6) (ounces)                            6,000,000-6,500,000
Total cash costs(3) (per gold equivalent ounce)                  $620 - $640
Total cash costs(3) - by-product (per gold ounce)                $280 - $300
----------------------------------------------------------------------------

 
Material assumptions used to forecast total cash costs for 2013
include: an average gold price of $1,700 per ounce; an average silver
price of $8.52 per ounce (calculated using the silver agreement
contract price of $4.12 per ounce and assuming excess silver beyond
contract requirements is sold at an average silver price of $30 per
ounce); and foreign exchange rates of 1.00 Canadian dollars and 13
Mexican pesos to the US dollar.  
Capital expenditures during 2013 are expected to increase to
approximately $42 million excluding capitalized exploration costs.
Underground development capital and sustaining capital remain at
similar levels to 2012, with approximately 49% of 2013 capital
expenditures allocated to projects and 51% to operations. The 2013
project capital includes the mill expansion to 2,500 TPD ($10.7
million) and the first phase of a two-year waste rock pad project
($6.8 million) designed to support the long-term (20 years) waste
disposal at San Dimas.   
Underground development in 2013 will again be focused in the main
mining (Central Block and Sinaloa Graben) blocks. In 
2013 the
majority of the ore is anticipated to come from the Central Block
with approximately 30% from the higher-grade Sinaloa Graben block.

----------------------------------------------------------------------------

 
Primero is committed to the safety, health and welfare of its
employees, contractors and visitors to the mine. Despite this
commitment, a tragic workplace accident occurred in 2012 resulting in
the death of an employee. As a result, the Company has conducted a
thorough assessment of its workplace safety program and plans to
reinforce and enhance its safety processes in 2013. 
Mine Exploration Success Leads Way for District Exploration Program 
Following a very successful 2012 exploration program which saw the
discovery of two new high-grade veins in the Sinaloa Graben and a 17%
increase in gold contained in Mineral Reserves at mid-year 2012,
Primero will be initiating a district exploration program in 2013.
The exploration work will be divided between District Exploration
(field activities and exploration drilling from surface on the San
Dimas property as well as the Ventanas property) and Mine Exploration
(delineation and exploration drilling and drifting from underground
in the San Dimas mine). The entire 2013 exploration plan is expected
to total approximately $15.4 million and aims to increase reserves
and resources and define higher-grade underground ore.   
The San Dimas property covers an area of 24,825 hectares. More than
120 veins have been recognized, explored and some of them exploited
starting in 1928. However, the historic records show the outcrop of
more than 260 veins. To date, half of the San Dimas property is
completely unexplored, either because of the barren geological
capping or lack of basic geological reconnaissance. Therefore, the
potential to discover new economic veins regionally is considered
excellent.  
The Mine Exploration program includes approximately 54,000 metres of
diamond drilling and 3,900 metres of exploration drifting. The Mine
Exploration program will focus mainly on reserve and resource
development and the exploration for the extension of the known
underground veins. The majority of the delineation drilling is
planned for the Roberta/Robertita and Marina 1/Marina 2 vein systems
in the Central Block and the Victoria/Alexa and Elia/Aranza vein
systems in the Sinaloa Graben.   
The District Exploration program includes approximately 19,000 metres
of drilling and will focus mainly on new discoveries as well as on
the surface features of the known underground veins.   
The east-west tunnel that joins the north-south Sinaloa Graben
tunnel, connecting the historical main mining block, the Central
Block, with the new mining area, the Sinaloa Graben, is expected to
be completed in early 2013, significantly improving access routes at
the mine. The Company is also driving a second east-west haulage
tunnel approximately 250 metres below the first, that is expected to
be completed within 18 months and is designed to facilitate the
increased haulage associated with the mine expansion to 2,500 TPD.  
Three-Year Plan Shows Significant Growth  
Primero's three-year plan reflects the benefits of the investments
made during 2012 and that are planned for 2013 including anticipated
production from the Cerro Del Gallo asset commencing in mid-2015. The
Company's production profile (shown in Figure 1) reflects the
optimization of San Dimas to achieve its current milling capacity of
2,150 TPD by the end of the first quarter of 2013, the expansion of
San Dimas to 2,500 TPD by the end of the first quarter of 2014 plus
incorporates long-hole mining into the 2013 to 2015 mining
plan.(5),(7) 
Assumptions used to forecast total cash costs for the three year plan
include flat metals prices of an average gold price of $1,700 per
ounce; and an average silver price of $8.52 per ounce (calculated
using the silver agreement contract price of $4.12 per ounce and
assuming excess silver beyond contract requirements is sold at an
average silver price of $30 per ounce).  
The Company has designed the mill expansion project such that a
potential further expansion to 3,000 TPD can be achieved with minimal
capital and no down-time at the operation. The Company will continue
detailed engineering in 2013 for a potential expansion to 3,000 TPD
and, based on exploration results, could announce a further expansion
to 3,000 TPD before the end of the year.  
Cerro Del Gallo Acquisition Diversifies Production Base and Enhances
Growth  
Primero's proposed acquisition of the Cerro Del Gallo asset,
announced in early December 2012(5), will create a diversified, high
growth, competitive-cost precious metals producer in Mexico with
further consolidation opportunities. It will diversify Primero from a
single asset company to a multi-mine producer and delivers on the
Company's strategy of growth in low risk regions of the Americas.
Cerro Resources NL shareholders will own approximately 15% of the
issued common shares of Primero on a proforma basis.  
The proposed acquisition doubles Primero's reserves and triples its
measured and indicated resources(7) and will diversify and improve
its production profile. The Company's combined three year plan
forecasts production to increase by at least 80% to over 200,000 gold
equivalent ounces in 2015. The first production from Cerro de Gallo
is expected to occur in mid-2015(7).
At flat metals prices of $1,700 per ounce of gold and $30 per ounce
of silver, the forecast 2015 combined cash costs are expected to be
approximately $650 per gold equivalent ounce, or below $450 per ounce
on a by-product basis.
Assuming the transaction closes in May 2013 as expected, Primero
estimates 2013 capital expenditures of between $50 and $60 million on
the Cerro Del Gallo project.

(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 2012 was 416:1 based on the average realized prices of $1,715
per ounce of gold and $4.12 per ounce of silver. The ratio for full
year 2012 was 221:1 based on the average realized prices of $1,662
per ounce of gold and $7.52 per ounce of silver. The ratio used for
the 2013 guidance projection is 200:1 based on estimated average
prices of $1,700 per ounce of gold and $8.52 per ounce of silver.  
(2) As announced on August 2, 2012 in the news release "Primero
Reports Record Second Quarter 2012 Results; and Increases 2012
Production Guidance".  
(3) 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 (and copper in the case of Cerro de
Gallo) 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.   
(4) The preliminary cash cost information provided is approximate and
may differ from the final results included in the 2012 annual audited
financial statements and MD&A.   
(5) Assuming the successful closing of the Cerro Del Gallo
acquisition as announced by the Company on December 12, 2012 in the
news release "Primero to Acquire Cerro Del Gallo", available on the
Company's website www.primeromining.com or Sedar www.sedar.com and
that it begins production in mid-2015.  
(6) 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 $4.12
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.  
(7) Assuming Goldcorp Inc. converts their 30.8% position in Cerro Del
Gallo to a Net Profit Interest and that resources include reserves.
Cerro Resources NL has filed a technical report under National
Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI
43-101") entitled "Technical Report, First Stage Heap Leach
Feasibility Study, Cerro del Gallo Gold Silver Project, Guanajuato,
Mexico" (the "Technical Report") with an effective date of May 11,
2012. Mr. Gabriel Voicu, Vice President, Geology and Exploration, who
is a "qualified person" for the purposes of NI 43-101, has reviewed
the Technical Report on behalf of Primero. To the best of Primero's
knowledge, information and belief, there is no new material
scientific or technical information that would make the Technical
Report inaccurate or misleading. Primero plans to file a technical
report on the Cerro Del Gallo project within 180 days of December 13,
2012 in accordance with the requirements of NI 43-101.
