PROJECTVIABILITY
Golder Associates approaches the pre-feasibility stage of a mining
project from both a regulatory and an economic perspective. By
combining mining and environmental considerations, our mining
team is able to effectively understand options for the development
of the mineral resource.
Golder Associates integrated team of engineers and scientists is
able to provide complete pre-feasibility support. At an early stage.
Golder Associates efficiently addresses the balance between
environmental and engineering issues associated with the
development of a mining project.
We advocate a holistic approach to the development of new mining projects. Siting, waste management, mining methods, and water
resource issues are addressed in conjunction with environmental
impact assessment and closure planning.
The overall effect of this approach is a mining operation which
may be more readily permitted, due to the completeness of the
package, be more efficiently mined, due to the integration of all
operating parameters, be more cost effective, due to the advance
planning undertaken at the start of the mine life, and have limited
future closing liabilities.
The goal of the Golder Associates is to prepare a cost-effective
approach to evaluating, permitting, developing, and closing a mine.

Closure and Reclamation For issues related to closure and reclamation, mines are typicallyviewed as in one of two categories, these being historic facilitiesand new facilities.
With historic facilities, closure and reclamation planning wastypically not undertaken prior to mine development. In these
cases, Golder Associates engages in a risk-based approach, withthe aim to manage liability and reduce closure costs.
For more recently-developed mines, Golder Associatesincorporates closure and reclamation plans as part of theEnvironmental Impact Assessment (EIA) undertaken in the pre-feasibility and planning stages of mine development. This
proactive approach allows mine operators to deal withenvironmental issues before they become liabilities and to developmethods to minimize reclamation costs during the operating life of the mine.
Golder Associates is recognized internationally in the fields of reclamation and closure planning and design for closure. Our staff is highly experienced in developing strategies for concurrentimplementation during operations, with the objectives of minimizing impacts during mining, as well as minimizing risks andcosts associated with closure. Golder Associates approach toreclamation and closure planning is based upon current
technologies to achieve physical, chemical, and biological stabilitywithin each mine component, during operations, and in the longer term. Our overall aim is to restore pre-mining land use potentialand capability, or an acceptable alternative. Golder Associates isable to offer the client highly skilled staff with environmentalengineering, biotechnology, ecological, and agronomic expertise.Our Company has an exceptional track record in achieving thehighest mine reclamation and closure standards.
The ultimate goal of reclamation is to achieve an end land use of
equivalent productivity to the pre-disturbance conditions.Golder Associates has the expertise to recommend an appropriateend land use or uses and to quantify productivity requirements
based on the chosen end land use. Our professionals can thendetermine the remediation criteria necessary to achieve the

Water SupplyServices
Ensuring a viable water supply is, in many cases, the most critical
issue facing mine operators/planners. The challenge lies in
assessing the total water resources, both surface water and
groundwater, to ensure development of an optimum supply.
Constraints to such development may be imposed by the limited
supplies available or from competing requirements.
Golder Associates can draw on extensive hydrologic, civil
engineering, and hydrogeological expertise to evaluate and
develop wellfields and surface water reservoirs. For example, the
impacts associated with water supply sources are evaluated by our
environmental scientists and engineers who
may be faced with such problems as assessing
the impact on aquatic habitat of reduced
baseflow or the potential for erosion associated
with reduced lake levels. The consideration of
these impacts leads to an improved water
management strategy to minimize the risk of
supply disruption and support the development
of a proactive environmental program.

Water DiversionStructures
Golder Associates provides designs for water diversion and control
features for new and existing mine projects, beginning with pre-
feasibility studies, through site investigations, final design, and
construction. Our mining team also conducts environment site
investigations and supports projects with impact assessments and
mitigation plans.
Mine water control is often a primary factor in optimizing the
siting of the major project features including the water supply,
waste dumps, and tailings disposal facilities. In some cases, the
feasibility of the entire project can turn on the cost and/or technical
feasibility of a river diversion if the pit is within a river channel.
More frequently, the work involves design of simple freshwater
diversion ditches and channels around project features. Tailingsimpoundment water control is critical in wet climates to prevent
accumulation of excess pond water. In dry climates, water storage
is critical to a dependable water supply for a mine or mill. This
requires design of dams, ditches, and other water control systems.
For closure of existing sites with ARD,
Golder Associates has designed elaborate
water control systems using multiple dams andreservoirs, underground workings for storage
and conveyance, caps and covers, piping
systems with pumps and backup power
supplies, concrete channels with stilling
basins, and other features which serve to divert freshwater around
sources of potential contamination, and to collect potentially
contaminated flows for treatment. Where flows are seasonal,
storage is provided to produce a more uniform flow to the water
treatment facilities. We provide complete design and construction

Planning
The development of a comprehensive and effective environmentalmanagement plan assists in achieving regulatory compliance andminimizes future liability; it may also enhance profitabilitythrough loss control, optimization of operations, and minimizationof remediation and long-term site maintenance requirements. Anaccurate site baseline, as obtained through a biophysical andenvironmental impact assessment, provides realistic criteria for theevaluation of site management methods and determination of theeffectiveness of site remediation and reclamation methods.
In addition, the pre-development environmental planning processcan be used as the basis for the operational environmentalmanagement plan. Priorities for environmental management willhave been identified and mitigative measures developed. Impactsidentified after the mine becomes operational can be comparedwith pre-development predictions and baseline data, anddifferences can be used in modifying design criteria and wastehandling practices, or in identifying the influence of environmentalfluctuations.
The pre-development planning process requires expertise from awide range of fields, as a variety of different potentialenvironmental impacts must be assessed, and mitigation and
remediation measures must then be designed. Golder Associates provides a multi-disciplinary team with expertise in a variety of biological sciences, environmental management, and engineering.Field investigations and computer modelling are utilized todocument existing environments and to provide quantitative
predictions of development-related changes. This enables anevaluation of their significance. The data are then incorporatedinto project planning decisions to avoid, where possible, projectimpacts. Where impacts are unavoidable, practical and cost-
effective mitigation measures are developed.
The very nature of these projects requires a detailed understandingof regulatory requirements and strict attention to scientificcredibility. Golder Associates has the full range of expertise andexperience to provide services in all phases of this process.

schedules and costs, minimized approval conditions, long-term
positive relationships with stakeholders and regulators, and
minimized environmental and social liabilities.
Initiated at the project evolution stage, the EIA approach
advocated by Golder Associates is a balanced and interactive
process that involves continuous communication between the
project proponent, local communities, regulators, stakeholders, and
technical project teams. This ongoing dialogue ensures that
important issues are identified and documented early, are revisited
throughout the assessment, and are used to focus the baseline
environmental studies and impact analyses. Explicit decision
criteria are employed to ensure the data collection, quantitativeimpact analysis, and mitigation designs respond to the projects
primary issues and concerns. Issues which cannot be resolved are
subjected to further study and quantitative impact analysis.
The interaction of the environmental and engineering design teams
ensures that solutions are developed to resolve the issues.
Utilizing current technology (e.g. Geographic Information System
and Remote Sensing) and quantitative tools (e.g. Risk-Based
Assessment and Environmental Modeling), Golder Associates has
developed innovative cost-effective solutions for site selection
studies and evaluation of mining processing and waste
management options.

Biophysical and SoilSurveys
Biophysical investigations integrate the terrain, soil and vegetation
sciences in the description and analysis of landscapes for
environmental impact assessment and reclamation planning
purposes. Golder Associates multidisciplinary approach to
biophysical studies allows us to assess each of the main disciplines
separately and collectively relative to a given environmental
setting and development.
An ecological and land classification
(ELC) approach is used to identify
biophysical map units with a
characteristic assemblage of terrain,
soil, and vegetation conditions at a
variety of scales. Description of map
units may be used, in conjunction
with GIS technology, in
environmental issue scoping,
environmental impact assessment (EIA), environmental protection
planning (EPP), reclamation planning and environmental design.
Wildlife habitat assessments often utilise ELC map units as the basis for quantifying habitat quality and habitat use in both a local
and regional (including cumulative impacts) setting.
Soil surveys may be part of a biophysical inventory or a specific
focus of investigation to identify soil resource conditions, sensitive
(erosive) soils, soil capability for land use and soil suitability for
reclamation. Soil physical, chemical and biological data are used
to determine soil quality and the susceptibility of soils to
disturbance and to develop soil handling procedures required
during and after disturbance.

Wildlife Investigations Golder Associates Ltd. has extensive experience in wildlifeassessment. This expertise is used during initial planning and pre-
feasibility stages of development to conduct fatal flaw analyses,
baseline studies, environmental impact assessments and
cumulative effects assessments. These assessments include
recommended mitigation measures to minimise potential impactson wildlife. Data acquired during such studies also form the basis
for wildlife effects closure, to gauge the efficacy of mitigation
measures and as necessary to modify those measures.
Our biologists often work with groups of stakeholders, including
regulators and aboriginal people, to help set guidelines for wildlife
studies during all stages of mine development. Frequently, the
main concern is possible loss of wildlife habitat. We therefore link
closely to vegetation studies to quantify the importance of
vegetation as wildlife habitat. We employ Habitat Evaluation
Procedures (HEP) modelling, which links wildlife values to
vegetation types using a GIS format. Other capabilities include
wildlife inventories, wildlife distribution and abundance from
ground and aerial surveys, movement studies using radio collars,
behavioural observations and the study of food habits. Faunal
expertise includes ungulates, carnivores, bats, small mammals,
waterfowl, raptors and other birds. Geographical experienceincludes arctic, temperate and tropical regions.

Fisheries Issues related to water quality and fisheries are key concernsthroughout the life of a mine from exploration to closure. Baselinedata collection and impact analysis in these areas is a criticalcomponent in support of permit and licence applications. Duringmine operation and closure, monitoring of the quality of dischargeand runoff waters, as well as health and abundance of fish and
benthic invertebrates present in receiving waters, are frequentlyrequirements for permit maintenance.
Golder Associates services to mines include environmental impactassessments (EIAs), ongoing evaluation of water quality issues,design of operational monitoring programs, compliance monitoringof fisheries resources and fish habitat, and design and maintenanceof environmental protection plans. A practical, cost-effectiveapproach, which includes regulatory compliance and anunderstanding of ecological sensitivities, is stressed.
Biological studies focus on the potential for disturbance or alterations to aquatic habitats during mine advancement. Fieldinvestigations are used to evaluate habitat characteristics. If habitat losses occur as a result of mine development, mitigationmeasures can be developed to compensate for the shortfall.Golder Associates fisheries services include monitoring for increases in tissue metal burdens, taste alteration in fish flesh, and
population decline due to unrestrained angling. These can beuseful tools for the identification of key issues, which leads to
project-specific, cost-effective development of overall aquaticmonitoring programs.
Services relating to surface water quality include the use of mathematical models to predict changes in water quality due tomine development. The corresponding effect on aquatic habitatand aquatic animals can also be predicted. Impacts on receiving
water bodies from a licensed mine discharge(s) or from minedrainage can be assessed. Golder Associates also has thecapabilities for the simulation and design of functioning artificiallakes (wetlands) as a reclamation option.

Air and NoiseQuality Monitoring
Air quality can be affected by process and smelting plant
emissions, fugitive emissions, dust, and other particulates. Golder
Associates offers services to collect data on existing or potential
air quality, identify sources of emission and aid in design and
monitoring of mitigative measures.
To determine the effects of gaseous emissions
on air quality, meteorological and
climatological information is collected to
characterize ambient air. This allows
determination of where emissions will be
carried and in what concentrations.
If the emissions are from a stack, plume
dispersion modelling can be carried out to
identify any potential significant impacts. The
chemical properties of emission gases are
identified and compared to existing standards.
If concentrations of noxious gases exceed regulatory standards,
stack height, stack position, design, and process considerations can
be modified to meet standards. At the design stage potential
impacts can then be mitigated before problems occur.
Golder Associates can aid in the conceptual engineering aspects of
design and advise on monitoring programs when a system is in
place.
For fugitive emissions, approaches including modelling,
monitoring, and project review can be used. Conceptual design
solutions and monitoring programs can be developed and initiated.
Dust in the ambient air can be measured and used as a baseline
from which to compare dust levels during mining activity.
Sampling techniques vary from simple dustfall containers to a
high-volume sampling. If a problem is evident, the dust sources
are examined and dust suppression alternatives recommended.

Socio-Economic ImpactAssessment/Public
Consultation
Golder Associates provides comprehensive services in public
involvement and socio-economic impact assessment (SEIA).
Public involvement services range from the design and
implementation of public involvement programs to obtain
approvals for new or expanded projects, to renew
regulatory approvals, and to address community issueswhich arise during project facility operations and
decommissioning. SEIA services are developed to
meet regulatory requirements for new or modified
projects. In particular, the services identify benefits
and costs resulting from project development,
operations, and decommissioning and recommend how
the associated impacts can be best managed.
Golder Associates staff work with industry, government, andenvironmental/community organizations involved with
environmental planning and management and resource
development. As a result, we are able to apply an integrated range
of experiences to the challenges faced by our clients. Members of
our staff are also trained mediators.
For each project, Golder Associates develops a decision making
process which highlights key objectives, stakeholders to be
involved, and environmental, community and regulatory needs
unique to the project. Subsequent tasks are defined to verify
information used in the process and to develop responses to
address stakeholder issues.
Socio-economic assessments are based on project-related changes
to, or demands upon, land use, regional labour force, and regional
and local populations. Assessments determine the implications of
these project-related demands upon surrounding communities andeconomies and recommend how they can be effectively addressed.
Throughout our assignments, we work closely with clients
throughout both the development and implementation of the
programs and incorporate input from clients in addressing
stakeholder issues.

Cultural ResourceManagement
Golder Associates conducted anexcavation of a tipi ring site at the PrairieCoals Poplar River site in Saskatchewan.
Golder Associates has an in-house staff of archaeologists, able to
conduct feasibility studies and overview assessments of cultural
resources prior to the development of new mines and expansion of
existing mines. Our archaeologists utilize data from background
research, field reconnaissance, topographic maps, and satellite data
aerial photograph analysis to delineate archaeological sensitivity.By completing these studies well in advance of development,
information can be used in the project design phase to avoid costly
delays to operation.
Impact assessment studies seek to identify and assess cultural
resources on a property. This can include prehistoric and historic
period archaeological sites, standing structures, and trails. In many
jurisdictions, these resources are protected by law, and a permit to
proceed with development will be contingent
upon getting an archaeological clearance.
Mitigation, consisting of site mapping,
excavation, avoidance, or other procedures,
is sometimes necessary.
Cultural resources problems also arise at the
decommissioning phase. With the
burgeoning interest in our heritage, it is becoming difficult in some jurisdictions to
decommission mines. This is because the
structures themselves, due to their age, have attained historical
value which may warrant regulatory review and possibly
preservation.
Archaeology has a very broad public appeal. Interpretive displays
for open houses, local museums, and mine offices have proved to
be of great interest to the public and have enhanced the publics
awareness and respect for mining companies.
Cultural resources management is a necessary component of many
mining projects, and Golder Associates offers a very pragmatic
and comprehensive approach.

EnvironmentalManagement
As corporate responsibility for environmental management
increases, companies are faced with the need to incorporate these
issues into their strategic plans. Golder Associates provides a
range of environmental management services that can help to
achieve cost-effective, proactive environmental management,
achieving regulatory compliance and a positive environmental
image in the community. Environmental management should be
responsive to community needs, and should promote
understanding, participation, and commitment at all levels of the
company.
Mining companies require environmental management plans or
systems for a number of reasons. There is a need to be able to plan
over a reasonable time frame for costs associated with remedial
measures or environmental improvements. In addition, an
effective environmental system can save money and allow a
planned response to environmental requirements while minimizing
the environmental liability of a corporation and its officers.
Should an environmental problem occur, these plans will serve to
demonstrate due-diligence on the part of the company.Development and implementation of an environmental plan
demonstrate to financial and regulatory agencies of environmental
control and awareness.
Environmental management plans and systems have the potential
to prevent environmental liabilities from impacting the value of a
company. Long-term planning to achieve cost-effective
decommissioning or close-out of an operation can be achieved
through environmental planning.

Annual EnvironmentalReviews
An annual review of the environmental management system
considers the manner in which it is being implemented and the
effectiveness of the procedures outlined in the plan. It can be an
effective means of ensuring environmental compliance, and a
powerful tool for controlling environmental costs, preventing
future environmental liabilities and difficulties with site
remediation.
The review should address the nature and quantity
of wastes and emissions, and the effectiveness of
waste management procedures. The need for
optimization of specific processes, operations, or
waste handling techniques can be identified. The
potential for additional unforeseen environmental
impacts from the site can be determined.
Aspects of environmental management which can be included as
part of the annual review include:
identification of changes in processes or materials handlingsince the previous review; changes which might createadditional environmental impacts;
annual variation in environmental impacts of miningoperations such as drainage patterns, precipitation, wildlifemigration patterns;
review and assessment of annual monitoring data; and
potential for site erosion/adequacy of erosion control

Risk assessment can be an effective tool in minimizing potential cost ramifications associated with waste disposalliabilities. The risk can be in terms of engineering performanceor in terms of ecological impact. In either case, risk assessment can be the tool to evaluate potential costs so thatrisk management can proceed on a rational basis.
The most economic closure plan begins with a rational designof the facility during feasibility level work. If the facility isalready operating, an evaluation of the technical issues canfocus the closure planning so that costs are minimized.
Risk assessment can also be used to ensure that long term,costly monitoring plans meet the minimum needs to measureengineering performance and environmental impact of theclosed waste facility.
