Environmental Stewardship
PDAC has long been an advocate for the industry to improve its social, environmental and health & safety performance both at home and abroad. We were the first industry association in the world to develop detailed guidance for companies on how to explore responsibly.
Toolkit
The excellence in Environmental Stewardship (EES) e-toolkit promotes the advancement of environmental stewardship in the exploration stage of mineral development worldwide.
The EES toolkit has been separated into sections which include an introductory description and a printable PDF file. See the left menu for a full list of sections within this toolkit.
Welcome
Welcome to the Environmental Stewardship Toolkit
The Prospectors and Developers Association of Canada (PDAC) welcomes you to our Excellence in Environmental Stewardship (EES) e-toolkit. The development of the EES e-toolkit was based on the principles set out in the following Mission Statement:
The EES e-toolkit program will promote the advancement of environmental stewardship in the exploration stage of mineral development worldwide. It will provide rapid access to the most up-to-date information, in the most accessible multimedia formats, for the purpose of encouraging the implementation of sound environmental management practices by the exploration community, its contractors, and subcontractors.
Exploration practitioners are the primary audience for EES e-toolkit and the content is written for, and directed to, them. In addition to providing guidance for exploration personnel, e-toolkit will also educate other stakeholders about current mineral industry good practices and promote a better understanding of responsible environmental stewardship in exploration.
The e-toolkit lets exploration professionals, and other interested individuals, zero in on relevant industry and environmental practices. You can explore these on-line or create a PDF version of selected practices to print for your reference.
The e-toolkit Web site is organized by issues (e.g., Planning Needs, Land Disturbance, and Site Management). When you are designing your exploration program by activities (e.g., Land Acquisition, and Surveys), you can go straight to the relevant issue to find the practice guidelines for that activity. Because of the content in any one activity is similar, or identical, to that of other activities each issue is organized as a "stand alone" section, to avoid duplications of effort and waste of resources.
There are up to five sublevels of information in this site, so a brief examination of the Table of Contents does not reveal the extent of the detail available to you. In general, the level of detail in any particular section increases the further down in the sublevels you go. The "upper" levels are designed to give more general information, and the "lower" levels to supply more specific detail.

Introduction
The Excellence in Environmental Stewardship (EES) e-toolkit is a comprehensive and up-to-date on-line resource for environmentally and responsible exploration practices and issues. Throughout the e-toolkit, emphasis is placed upon planning for avoidance of adverse impacts wherever possible. Taking account of the potential impacts before initiating an exploration program helps to ensure that exploration professionals leave as light a footprint as possible during their work.
EES e-toolkit is designed to provide guidelines to current professional practices, not prescriptive solutions to specific issues. The e-toolkit can, however, form the basis for individuals and companies to set up more detailed guidelines for their own activities. EES includes information on measures and practical options to minimize the environmental impact of exploration, anywhere in the world.
Archaeological and Cultural Sites
Introduction
From time to time, exploration crews may become aware of, or suspect that, sites of archaeological or cultural significance are located on lands to be explored, or which are being explored. This is a critical issue that must be addressed during the planning or execution of any exploration program. Failure to do so may create serious legal difficulty and lead to significant conflict with local people. There is no surer way of creating conflict than desecrating, however unintentionally, a grave or a place of worship. Many jurisdictions have laws and regulations pertaining to the protection of archaeological and cultural sites. As professionals, explorationists must have knowledge of these laws and be in compliance with them.

Introduction
In its early stages, exploration generally has a low environmental and socioeconomic impact. Consequently, the need for rehabilitation is modest and it is possible to take the steps to remediate a disturbance quickly. As more detailed exploration proceeds, the impacts increase correspondingly, as do the requirements for effective mitigation.
EES encourages a proactive way of looking at the issue of environmental impact - to avoid it in the first instance wherever possible. This proactive approach also encourages taking into account the total cost of a program, rather than just the direct cost of carrying out a particular activity.
Proper planning and consideration may result in new and improved approaches. Asking whether a program will have more or less impact on the natural and social environment may lead to a decision to use different, perhaps newer, technology to achieve the same aim.

Introduction
This section describes the natural causes and consequences of erosion, and how exploration activities can accelerate erosion processes. It then details the steps to take to control erosion during exploration activities. In addition, it explores the unique vulnerabilities of special terrains to erosion.
Erosion is the wearing away of the land surface in response to natural forces such as wind and rain. These forces cause the materials of the earth's surface to loosen, dissolve, or wear away, then to be transported from one place to another by natural agents. The result is a change in the shape, and often the usefulness, of the land surface.
Erosion is accelerated by exploration activities. Understanding the causes and consequences of erosion makes it possible to better evaluate and select methods to mitigate and control the impact of exploration.

Introduction
The primary goal of a site management system is to ensure every person entering the site completes their business in a safe, environmentally sensitive and effective manner. This includes: contractors; visitors; inspectors; and senior company management.
For the purposes of this e-toolkit, a site is any area where exploration and related activities are conducted by the company, its employees, contractors, and subcontractors, whether or not the company has land tenure. The following two examples would both be considered sites worthy of inclusion in a site management system:
The location of a contracted prospector's parked truck on the shoulder of a highway, while the prospector is on a reconnaissance traverse. The boat or floatplane loading area of a public dock.
As described in the Management Essentials section of this e-toolkit, site selection planning is an important factor in the safe and successful completion of any exploration program. Although access to water for consumption, hygiene, overburden stripping, sluicing, drilling, and transportation is an important factor in the site selection process, also consider the effects that the selection will have on soil erosion, local and regional water resources, ecosystem health, and future exploration programs.
Mining operations often take advantage of infrastructure established by exploration crews, so planning (especially roads and camps) should consider potential long-term effects. In addition, be aware that water management and soil erosion control forms the bulk of environmental control activities at operating and closed mine sites.

Introduction
The role of reclamation and closure in any mineral exploration project can be regarded as the final chapter in the life of that project. When the exploration project develops further into a feasibility study or a full-scale mining operation, however, then the reclamation process undertaken at the exploration stage becomes the first step in the final rehabilitation of the mine.

GHG Emission
Calculator
The GHG Emissions Calculator is designed to capture the majority (75 percent+) of GHG emissions produced by a company's exploration stage activities and provide a ‘ball park’ estimate of emissions produced.
The GHG Emissions Calculator can also assist companies in understanding the 'cost' of a fossil fuel charge per the federal backstop based on fuel use and GHGs emitted.
Caribou Management Strategies
In the summer of 2021, PDAC completed their Caribou Management Strategies: Best Practices for the Mineral Industry study, to analyze the impact of exploration and mining activity on caribou populations and provide solutions to mitigate this impact. Led by a third party consultant, the research was informed by company case studies, outlining industry leading practices from operations of various sizes and jurisdictions.
This project will serve as a tangible resource for PDAC members to understand strategies to mitigate caribou disturbance at each stage of the mineral development sequence, from exploration to closure.
Land Disturbance
Report
This study presents a methodology to estimate the physical disturbance of mining and mineral exploration projects across the mineral development sequence, from early exploration through to mine closure. The methodology uses satellite imagery of exploration and project sites to estimate disturbance associated with different stages of the mineral development sequence.
Commissioned by Land & People Planning (L&P), in partnership with O2 Planning and Design (O2), the report was published by PDAC and MAC in Fall 2023.
