Our goal is to maximize the underlying value of your mineral resource by employing the correct project concepts, in alignment with your corporate goals and development strategies. We will rigorously prepare an optimized mine plan using proven methods that provide production surety. We know what works, and which issues constitute opportunities and risks.

Teams of consultants are assembled to meet the unique needs of each project. Our services consist of the preparation of scoping studies, mining pre-feasibility and feasibility studies for both underground and open pit mine projects.

Services

• Mining scoping, pre-feasibility and feasibility studies
• Mining method analysis and selection
• Estimation of mineral reserves
• Optimization of production rate and sequencing.
• Estimation of equipment and manpower requirements.
• Mining logistics and infrastructure design.
• Project execution plan.
• Capital and operating cost estimation.
• Financial analysis modelling and valuation

GADWA Consulting has a team of professional and technical staff who provide innovative, computer-based data integration, management, and presentation services for a wide range of earth science disciplines. Extensive quantities of data may thereby be made readily accessible and meaningful, providing a basis for clients to make and review decisions in real time. Including the management of tailings dam complexes; site characterization; geological, hydrological and geotechnical exploration, and environmental mapping, assessment, monitoring and remediation.

Services

• Geographical information systems
• Integrated information systems
• Integrated information management
• Environmental database
• Geological mapping

Our geologists have extensive experience in exploration, database management, geological modeling, geostatistics, resource estimation, and.  Conditional simulation we help take your project from grassroots exploration through the feasibility study stage and into production. Our approach to resource estimation combines our strengths.

Services:

• Evaluations of exploration properties.
• Reviews of exploration sampling results and QA/QC procedures.
• Optimization of drill hole targeting for resource definition.
• Exploration and database management.
• Statistical and geostatistical analyses.
• Resource estimation, classification and reporting for all stages of projects from scoping studies through to feasibility studies and operating mines.
• geological interpretations and resource estimates

Successful exploration relies on efficient project management based on effective application and interpretation of geology, geochemistry and geophysics to generate and test exploration targets. Our core exploration management services deliver on testing targets, from grassroots to resource definition drilling projects. We also provide economic assessments and project evaluations.

Services:

• Project planning, permitting and implementation.
• Drilling contracting and contract management.
• Core logging and cutting.
• Geotechnical and water logging and monitoring.
• QA/QC design and implementation.
• Assay contracting and management.

Geological mapping is fundamental to any exploration project. Effective mineral exploration requires an in-depth understanding of the lithological and structural controls of mineralization. These insights must be gained through geological mapping at the early stages of the exploration program.

Services:

• Base mapping.
• Drill core logging.
• Structural mapping to define geometry and mineralization controls at regional to mine scales.
• Alteration mapping to define controls on mineralization.
• Expert analytical support to solve specific issues (e.g. petrography, alteration, age-dating, fluid inclusions).

GADWA provides specialized exploration services. These include advanced structural interpretation skills, the ability to connect mineralized systems to the structural setting, systematic data- and knowledge-driven mineral potential mapping, and 3D geological and geophysical modeling . Our consultants are experts in the formation and distribution of minerals within a wide range of geological and tectonic settings.

Services:

• Structural and alteration analysis (drill core and surface exposures).
• Mineral system analysis.
• Structural interpretation of geophysical data at all scales.
• Data- and knowledge-driven mineral potential mapping.
• 3D geological modeling.
• Regional exploration potential assessment.

The collection of reliable samples from a mineral prospect or mine is an essential basis for the production of an accurate resource estimate. The strategy to be adopted must thus be carefully designed so that at each stage of the process, the chance of taking biased, unrepresentative or contaminated samples is minimized.

Sampling and sample preparation protocols should be designed to produce the highest possible data quality given the nature of the target mineralization and the ground conditions.

GADWA provides an integrated program to design, manage and audit sample collection and preparation procedures on behalf of clients in both the mineral exploration and mining industries by the supervision and auditing of exploration drilling programmers undertaken as part of exploration projects and mine feasibility studies and also by the performance monitoring of operating mines. In addition, sampling programmers have been designed for base line environmental geochemical studies and for the assessment of contaminated mine sites.

Services

• Optimum sample length, volume or weight and compositing strategy in relation to the physical characteristics of the mineralization.
• Optimum sampling methodology and collection procedure to minimize contamination, avoid loss of fines in the case of rotary percussion drilling and to produce representative unbiased samples.
• The establishment of on-site supervision and checking procedures for drilling and sampling programs.
• Monitoring of sample recovery.
• Sample homogenization and splitting procedures.
• Duplicate sampling at each stage in the reduction and splitting process to determine the magnitude of errors at each stage.
• Quality control procedures to monitor sample preparation and analysis at the mine or commercial laboratory.
• Replicate sampling and analysis to determine precision of sample grades.
• Comparative studies between assay laboratories and determination of accuracy.
• Compatibility of assay databases produced by different sampling campaigns.
• Integration of historical data into current exploration efforts.
