Mineral exploration is the process of discovering minerals containing valuable materials, often on the surface of the planet or, increasingly, at depth.

The key aspects of exploration are really to further develop your understanding of the geology. From an initial analysis, companies may consider further expenditure, often using the techniques of geophysics or geochemical analysis to enhance existing data to drive informed decisions on future drill programs.

“GREENFIELDS EXPLORATION” is where exploration companies go into remote locations where few people, if anyone, has looked before.

“BROWNFIELDS EXPLORATION” is defined as exploration close to existing mines, trying to find new satellite type ore bodies that can be fed into the existing processing plants.

SMGC has experience in all aspects of exploration from greenfields to brownfields exploration of provincial scale concessions, to pre-production, extending existing operations and grade control sampling.


Geophysics uses a lot of computer power to process data collected in the field to enhance it and extract the content to be used in the geological interpretation we display as geophysical maps, images and 3-D models. These images and models are then interpreted by the geophysicist or the geologist to extract and convert the geophysical information into geological information. This is used to target minerals and pass on to the next stage of the exploration process.

Using Minex, Surpac, Micromine, Minescape, acQuire and other mining software, SMGC is able to collect, manage and interpret the data required to build geological models. In partnership with our clients, the planning and supervision of drilling programs can be conducted using state-of-the art software. Geological data can be enhanced by interpreting magnetics, gravity, radiometric and seismic data.


Geophysics is the study of the interior of the earth using principles of physics. This means taking measurements at or above the earth’s surface to find out what’s beneath our feet and creating an image of those geological features. The 3 dimensions that geophysics allows is like having X-ray vision, to look into the earth to see and understand the structure and history of potential ore bodies.

Geophysics in a mineral exploration setting allows us to look into the earth and identify structures and different rock types. We can’t necessarily determine what is gold, nickel, copper, or iron, but we do start to get a picture of the rocks that are either metal-containing or potentially metal-containing from those that are not.

The geology provides information on where rock types are or where there are changes between the rock types. The geophysical survey connects to the geological mapping. Often looking at connections between rock types in the third dimension, at depth, using geophysical techniques will give you this information.

To produce sound geological models, SMGC uses a variety of structural tools including wireframing, ore body geometry, seam or vein modelling and geostatistical skills. SMGC uses these models to provide technical advice relating to exploration and mining geology. We also like to use multiple methods at the same time or on the same area, to give greater confidence. Interpretation is the key to a valid geological model and Resource estimate. Geochemistry, geology and geophysics techniques are used together to give a more definitive indication of whether there’s a mineral deposit in the ground that’s worth excavating.


SMGC’s cutting edge pit optimisation techniques are able to incorporate all facets of the mine operation into true Life of Mine solutions. SMGC uses the Lerch Grossman and floating cone 3D pit optimiser to provide NPV-based LOM solutions that integrate full mine production scheduling. Whittle optimisation is another option that may be seamlessly incorporated.

Additionally, SMGC in association with Whittle consulting allows optimisation to be extended to full Enterprise Optimisation should the client require it.


The drilling phase of mineral exploration is the first time explorers can directly observe and analyse the rock beneath the surface of the earth. Drill holes can be targeted using geological maps, rocks observed in the field, magnetic or gravity geophysical data or geochemical information from soil samples where areas of elevated gold, coal, nickel, or other mineral levels form the focus of drilling efforts.

A typical drilling operation draws upon the expertise of geologists, geophysicists, field samplers, drillers and laboratory personnel. SMGC’s geologists determine the areas, spacing and priorities for the exploration drilling. Drilling rigs are then are used to extract samples from the site.

Drilling methods vary according to the size of the project area, budget, type of rock, topography, or mineral being targeted. Holes are drilled either vertically or at an angle to various depths. The rock is broken by the drill advancing through the rock or soil and returned to the surface as cuttings (small pieces of rock) or as core (solid cylinders of rock or clay). The drilled material is then collected and sent for laboratory analysis.

There are a range of exploration drilling methods that can be used but the most common methods are: reverse circulation (RC) and diamond core drilling.

SMGC works with a number of experienced drilling companies, dependent on the location of the concession and the type of mineral.


If we ask the question: “For every dollar invested in greenfields exploration, “do I get 50 cents back…”, which wouldn’t be very good, “..or do I get my dollar back, or do I get $1.50 or $2?”

SMGC provides high-level economic analysis as an important step in creating an Ore Reserve from a Mineral Resource. Economic analyses are based on pit optimisation and block ranking methods applicable to surface mining.

Economic analysis is also used to defermine the highest value strategic plan for the entire business from exploration through to geological modelling, cut-off grade analysis, pit design, scheduling, dumping strategy, equipment selection, mine operations, product blending, logistics and product marketing.


Evaluating, designing and scheduling the life of mine requires a rigorous planning process. Mine planning needs to address factors such as overall project value, sustainability, community expectations, mining methods, technical and practical considerations, infrastructure, processing, marketing and workforce options. Each planning stage considers the economic viability of the mine, weighing the business risks against the likelihood of turning a profit in a volatile mineral market.

Mine planning occurs every day in a mine, and it’s an ongoing process from pre-mining all the way through to depletion and mine closure. The purpose of mine planning is to connect the economics of what is believed to be in the ground from the exploration geology with the likelihood of being able to make a profit after investment in the mine, processing plant and other infrastructure.

How to mine it? How to process the ore into a product? How to transport the product? The mine planning function addresses these questions while considering the current commodity price exchange rates, costs, and grade of the ore body. All of these components will influence the revenue and cost streams, and thus the future cash flows for the project.

SMGC provides mine design and scheduling services for open cut and underground mines, with particular strengths in stratiform and thin vein deposits. SMGC is actively engaged in planning from high level conceptual studies through to operational planning. We support both pre-production and operating mines.

SMGC can provide the full cycle of mine planning services from short term operational planning to life of mine planning.


Mines require an incredible amount of equipment and resources to operate. Having found a deposit that can form a mine, consideration must be given to the infrastructure requirements. This includes the transport in and out of goods, materials and people. It will also require a power source, water supply, communications, healthcare and everything else to service the workforce on site.

Infrastructure planning can be complex and involve large investments. It is the engineer’s role to design, plan and build fit for purpose infrastructure on time and under budget. The project may need water, power, road, rail, port and other supporting infrastructure. Mineral deposits are seldom blessed with convenient locations close to existing transport, infrastructure, workforce and customers.

Mining projects will either build their own road and rail infrastructure as a cost of the project or in a joint venture with other third parties or state authorities, particularly if there is a social benefits to nearby communities or the transport options become part of the state’s infrastructure. The same applies to port infrastructure, where companies may either build their own land-based port infrastructure or enter into arrangements with third parties or government authorities.

SMGC can help with infrastructure planning including, material handling, processing, power, water, haul roads, ports, camps and other project specific requirements. SMGC also helps mining companies to improving the efficiency and effectiveness of their existing assets. By considering the entire business, SMGC can interrogate current operations and provide an optimised plan to move forward.

Due Diligence is a series of in-depth and comprehensive inspection and tracking processes with the aim of obtaining material information from a target company before a transaction or business cooperation is conducted.

The Due Diligence process aims to determine the potential risks and opportunities associated with the target project. This is done through a systematic process of enquiry, observation, investigation, analysis and verification of key aspects of the project being considered. Due Diligence is also conducted to determine the economic, technical and practical feasibility of projects. This can include the verification of reported mineral Resources or Ore Reserves.

Thorough Due Diligence studies demand the ability to examine in detail the essential factors that affect the final appraisal of a property. SMGC’s senior staff have a wealth of experience to guide clients through the potential risks and opportunities they may encounter.

Drones have made it possible to map a mining concession area very quickly in a very cost-effective manner, compared to the traditional methods of ground survey, manned aircraft and satellite imagery. The mining industry is now extensively using drone mapping and surveying, to monitor mine operations and conditions. Drone surveys can also be used to measure surface elevations and volumes to track the progress of mining, dumping and stockpiling operations against the plan. With this almost real-time monitoring, prompt remedial actions can be implemented to re-align operations to restore compliance with the mine plan to maximise project value.

Surveying with a drone offers enormous potential. With a drone, it is possible to carry out topographic surveys of the same quality as highly accurate measurements collected by traditional methods, but in a fraction of the time. Often it is possible to capture the entire pit, dumps and mine infrastructure in one detailed flight. This provides engineers and planners with a greater understanding of the entire concession. This substantially reduces the cost of a site survey and the workload of specialists in the field.

SMGC owns a variety of drones that are being used for surveying, mapping and general data collection during site visits. This provides SMGC’s engineers with a greater insight of the whole project and the ability to advise clients on a “Live” basis.

The use of drones by SMGC during Due Diligence assignments allows a rapid assessment of the site with recorded evidence of any observed issues.

Mine site power is key to mining operations and costs. SMGC can provide innovate power solutions based on each concession’s specific requirements.


One of the key decisions facing surface mining operation is the selection of the optimum equipment combination. This can include conventional truck and shovel systems as well as other alternatives such as in-pit crushing and conveying (IPCC), surface miners and draglines. SMGC can assist with this initial selection based on various site factors and then then further optimise the selected system.


SMGC can provide clients with in-house training in exploration, geology, engineering and mine planning for technical or non-technical participants.


As required, SMGC will collaborate with different industry partners to bring in specific expertise to suit the requirements of each project.


QA/QC programs need to be carefully designed and implemented at all stages of exploration and development where sampling of material is undertaken. Furthermore, QA/QC programs require review prior to, and during, each sampling program with modifications made where necessary based on numerous factors such as sample type, size, and the proposed sample processing and treatment methods.

QA/QC is required to ensure all geological data generated over the course of a sampling program (exploration or development) adheres to the key fundamental aspects of:

  • Accuracy – the degree to which an analysis is reflective of the expected result.
  • Precision – the repeatability of the result, and
  • Identification of sampling failures/errors/contamination.

SMGC’s geologists provide and train clients with QA/QC procedures based on the requirements each specific project.


Trenching or test pits can be a key part of the exploration process where conditions require a certain method of sampling to remove overburden that is covering the mineralisation.

Trenching involves removing a shallow amount of surface material to expose a vertical section of mineralised zone.

SMGC can assist with the design of the trenching plan and QA/QC support. SMGC can provide onsite assistance and support to client throughout the process.
