Sustainability Report 2011

About This Report

We at Primero are proud to present our first annual
Sustainability Report*, which highlights our achievements
and challenges in our first full year operating the San Dimas
mine. We acquired San Dimas in August of 2010 from
Goldcorp Inc., a company with established and respected
sustainability practices.

* The 2010 Sustainability Report reported on the five months in 2010 after Primero’s acquisition of the San Dimas property.
All currency is in United States dollars (USD) unless otherwise noted.

PRIMERO SUSTAINABILITY REPORT 2011 1

As we continue along our path to becoming a leading mid-tier gold producer, we are committed to supporting sustainable policies
and practices in mine exploration, development and operations. Corporate responsibility is embedded into our daily activities. Our
goal is to continuously improve workplace health and safety, and environmental performance, and to share the benefits of mining
with our local communities.
A key component of our commitment is transparent, accountable sustainability reporting. Our Board of Directors and senior
management team have committed to the sustainability reporting process, and are working to improve data collection and to
encourage employee engagement in all of our sustainability initiatives.
As a public company, Primero’s financial results are audited annually and reported on a regular basis. Our Annual Reports, Financial
Reports and Regulatory Filings are posted on our website. Therefore, economic performance is not emphasized in this report.

GRI Declaration
This report is based on the standards of the Global Reporting Initiative (GRI), and is the first step in our target for 2012, which is
to achieve a GRI level C standard of sustainability reporting. The GRI is an independent institution that has developed voluntary
guidelines for sustainability reporting. We believe that GRI guidelines help us to maintain a high standard of transparency, clarity
and comparability, and that applying GRI standards demonstrates our commitment to transparent reporting, especially in those
areas that are most important to our stakeholders.

2 PRIMERO SUSTAINABILITY REPORT 2011

Our Sustainability Policy

At Primero, we believe that sustainability is fundamental to
our success. Our prosperity depends on our performance—
at the corporate level and in our relation to our host
communities—in the three pillars of sustainability:
economic achievement, community engagement and
environmental stewardship.


By maximizing earnings and reducing operating costs, we produce results for our
Economic achievement shareholders while also contributing to the economic and social development of our host
communities.

We actively engage in meaningful dialogue with local residents, community leaders
and organizations to identify opportunities and priorities for economic improvement,
Community engagement better training and social development. We support schools, health care and local
infrastructure, and we continually seek development opportunities that will contribute to
a self-sustaining economy in the communities surrounding our operations.

At all times, we seek to operate in a responsible manner and to minimize the impact our
Environmental stewardship operations may cause to the environment. We operate with an awareness of the mine’s
life cycle and practice the progressive rehabilitation of areas affected by our activities.


Letter from the President and CEO

I know I speak for everyone at Primero in saying that growth and
profitability are not at odds with environmental and community
sustainability. In fact, we believe that we can only thrive when our
local communities share in the benefits of mining and welcome our
presence, and when we act with responsibility, transparency and
accountability.

Over this past year, we have maintained the high standards set by Goldcorp, and in some areas,
improved on previous practices. In our health and safety performance, for example, the number
of reportable incidents declined for the sixth consecutive year. As a result of our efforts, the
Mexican Centre for Philanthropy named us an ESR (in English, a Socially Responsible Enterprise).
To achieve this sought-after designation, we were evaluated against rigorous standards of
quality-of-life, business ethics, community engagement, and environmental stewardship.
Despite the overall improvement in health and safety, I am sorry to report a worker’s death in
2011, and I extend my personal sympathies to his family. We take this incident very seriously,
and initiated a thorough investigation. Our experts reviewed our safety training and ensured
that everyone, working directly or indirectly for Primero, had their safety training reviewed
and refreshed.
For 2012, we have set out a number of CSR objectives. While they are ambitious, I am certain
that our teams are capable of meeting every one. Regarding health and safety performance,
I want to see the number of workplace accidents reduced by 50%, and of course, zero
fatalities. That will only be the first step in making San Dimas a “triple-zero” operation by

Focused on Production: the San Dimas Mine

The San Dimas mine is located in central west Mexico, in the
State of Durango, approximately 150 km west of Durango and
125 km northeast of Mazatlán. The mine is 100% owned by
Primero. The San Dimas gold-silver deposit is one of the most
significant precious metal deposits in Mexico in a very large
mining district.


As we continue along our path to becoming a leading mid-tier gold producer, we are committed to supporting sustainable policies
and practices in mine exploration, development and operations. Corporate responsibility is embedded into our daily activities. Our
goal is to continuously improve workplace health and safety, and environmental performance, and to share the benefits of mining
with our local communities.
A key component of our commitment is transparent, accountable sustainability reporting. Our Board of Directors and senior
management team have committed to the sustainability reporting process, and are working to improve data collection and to
encourage employee engagement in all of our sustainability initiatives.
As a public company, Primero’s financial results are audited annually and reported on a regular basis. Our Annual Reports, Financial

Focused on our People

Our people, both employees and contractors, are our greatest
asset. Our success depends on the skilled, hard-working
people who work in the San Dimas operation, and in return
we seek to maintain a culture of safety in which everyone is
continually reminded of the importance of keeping themselves
and their colleagues healthy and injury-free. We treat people
fairly and without discrimination, with full regard for their
human rights.

Focused on the Environment

At Primero, our environmental focus is to act with
responsibility and transparency in developing mining
projects, and to proactively seek to minimize the footprint of
our operations. Precautionary measures are taken to avoid
damage to ecosystems wherever possible. When adverse
impacts occur, integrated programs are implemented to
promote the recovery of the affected ecosystems.

In Closing

As a relatively new company operating a long established
mine, Primero finds itself in a fortunate position. We inherited a
strong safety record, solid environmental policies and practices,
a motivated workforce and well-established relationships to
the local community where mining has been a way of life for
hundreds of years.


For the near future, our primary concerns and objectives focus on improving our environmental practices. While we have always been
in compliance with the regulations that are in force, we are advancing our standards. I feel it is important to report a recent tailings
spill that occurred in early 2012, after the period covered by this report. Although the spill was minor, the result of a leak in the pipeline
feeding the dry tailings facility, it triggered a thorough review of our containment systems. We have taken a series of corrective actions
and ran a preliminary assessment to confirm that there has been no residual impact on the aquatic life of the Piaxtla River. In 2012 we
will improve the containment structures for the tailings pipe and conduct an external assessment of the river.
We will continue to maintain a culture of safety at Primero and I am confident that we can achieve our aggressive goal of a further
50% reduction in workplace accidents in 2012.
I would like to take this opportunity to thank everyone at Primero who has contributed to our collective efforts in health, safety,
environmental stewardship and socio-economic sustainability. Through 2012 and beyond, I look forward to continued development
and improvements to our corporate culture of safety, respect and responsibility to each other, our communities and the environment.
