MINE PLANNING AND MINERAL EVALUATION Golder Associates is a global company providing a comprehensive suite of integrated mining services, from concept study to mine closure. Golder has extensive practical experience in all aspects of design, planning and operation of open pit, underground and strip mines, enabling clients to realise the maximum value from mining projects. With 160 offices, our clients have access to pragmatic mine planning and mineral evaluation solutions, no matter where their mining project is located throughout the world. EXPLORATION Golder assists in establishing and managing exploration programs to ensure appropriate data is efficiently obtained and evaluated. These services include: QQ Drill program design and management QQ Quality control and quality assurance QQ Sampling studies QQ Data capture and database management QQ Integrated data presentation QQ Geographical Information System (GIS) using regional and local data GEOLOGICAL INTERPRETATION AND MODELLING STATISTICAL AND GEOSTATISTICAL ANALYSIS Golder uses geological interpretations to develop robust geological and geometallurgical models that characterise the many attributes of the deposit including, grade, density, material types and geotechnical features. Golder evaluates the accuracy, precision and representativity of quantitative data inputs for sound resource estimation. These services include: QQ Data compilation and validation QQ Downhole geophysics QQ Validation of logging and mapping QQ 2D (stratigraphic) and 3D (block) geological modelling considering mineralogy, geochemistry and structures These services include: QQ Exploratory data and variogram analysis QQ Cross validation QQ Geostatistical estimations using both linear and non-linear techniques QQ Resource classification QQ Conditional simulations QQ Reconciliation of predictions, including against actual performance QQ Risk assessment QQ Feed variability characterisation QQ Drill hole density assessment and optimisation MINE PLANNING AND MINERAL EVALUATION Mine planning and mineral evaluation is the process of using various types of information, including geological, geotechnical, metallurgical, and other data to develop mine designs, production schedules, equipment lists, manpower numbers and cost estimates to enable the technical and financial feasibility of a project to be determined. MINING ENGINEERING Golder has extensive experience in the evaluation, design, development and management of both open pit and underground mines. Leading industry software is used for mine design, open pit optimisation, production scheduling, cost estimation and cut-off grade optimisation. These services include: QQ Pit and underground mine optimisation QQ Mining method selection QQ Mine design QQ Mine waste planning and design QQ Blasting design QQ Production scheduling QQ Equipment selection and scheduling QQ Manpower estimation QQ Capital and operating cost estimation QQ Financial modelling QQ Strategic (Life of Mine) reviews QQ Operational mine management reviews QQ Training RESOURCES AND RESERVES Golder develops realistic approaches to resource and reserve estimation that add value and form the basis for mining operations with attainable production targets. Golder is retained by mining clients because of our record of determining and developing innovative approaches to resource and reserve definition. These services include: QQ Mineral Resource and Mineral (Ore) Reserve estimation, validation, review and audit QQ Preliminary assessment (concept/ scoping), preliminary feasibility and feasibility studies GRADE CONTROL (ORE CONTROL) Golder’s customisable grade control system assists mining geologists to produce ore blocks optimised to meet targets and maximise profit. Golder’s Ore Block Optimisation (OBO) software helps ensure ore blocks are optimal, repeatable, consistent and available in a timely manner. These services include: QQ Ore block design QQ Ore block optimisation QQ Conditional simulation QQ Production reconciliation QQ Training TECHNICAL AUDITING AND COMPLIANCE Golder provides reviews and audits to confirm that Mineral (Ore) Reserves meet appropriate reporting codes and international best practice. Golder prepares technical documents as part of the listing or reporting requirements of stock exchanges and lenders in all jurisdictions. Competent (Qualified) Person statements QQ Audits and reviews for due diligence and governance. QQ MINE FEASIBILITY STUDIES Golder routinely performs mine planning and mineral evaluation that encompass all aspects of the investigation, design, economic analysis and resulting investment decision-making of potential mining projects for all sectors of the mining industry worldwide. Mine planning and mineral evaluation work is often integrated with Golder’s other consulting, design and construction services in the areas of: QQ Tailings and waste management, including heap design and construction QQ Rock mechanics and mine geotechnical engineering QQ Environmental services QQ Hydrology and hydrogeology QQ Mine infrastructure QQ Mine energy optimisation and carbon management QQ Sustainability and corporate social responsibility QQ Mine safety and industrial hygiene These services include: QQ Compliance with all international codes QQ Technical reports and prospectuses ENGINEERING EARTH’S DEVELOPMENT, PRESERVING EARTH’S INTEGRITY.
