Mine exploration management services

Gemecs will plan, manage and supervise your mine exploration activities. This includes field liaison with surface owners and other specialists, core logging, sampling services and data capture.

Borehole-database management services

Gemecs will setup and design a borehole database to suit your needs, and import and standardise your current spreadsheet data to the geological database.

Analytical lab data is also checked and verified using specialised routines, to ensure a clean, validated database. Graphical output logs are designed according to your needs and are produced as PDF files for secure storage. Gemecs also performs audits on existing borehole databases.

Geological coal resource modelling

Gemecs specialises in coal resource modelling. We will create a geological model from base principles and deliver a geological model, coal washabilities and products, JORC and SAMREC-compliant resource statements are provided and competent persons report to the client. Together with our mining engineering partners, we are able to deliver a full feasibility study.

Although we specialise in coal modelling, we have the expertise and experience to also model other layered ore bodies using Gemcom Minex™ – geology and mine planning tool for coal / stratified deposits.

Mineral-potential prospect permit studies

Gemecs perform desktop studies to evaluate mineral potential on prospect permits, as well as indicative resource estimations. We also have the capability to assist with prospect permit applications and renewals, as well as provide expert advice on mineral rights issues.

Audits and due diligence studies

Gemecs is available to perform resource-compliant audits and due diligence studies.

Geological and mining engineering software training and support

Gemecs provides training and support to users of the Gemcom Minex™ suite of geological and mining engineering software throughout South Africa. We use the Gemcom Minex™ software system for all our computer-based studies and consulting work.

Gemcom Minex™ provides the best geology and mine planning tools for coal and other stratified deposits, ensuring resources are evaluated accurately and mined efficiently. Minex has been designed to rapidly evaluate large, deep and data-intense deposits such as coal, bauxite and platinum.

Developed in partnership with the mining industry, the software is employed by the world’s largest mining companies to model, optimise, design, schedule and rehabilitate even the most complex faulted deposits. As a single, integrated system spanning exploration through production scheduling, data and skills can be readily moved between teams at significant time and cost savings.

Coal quality, core logging and sampling training and support

Gemecs provides training in basic core logging and sampling techniques. Our courses are specifically designed to train young geologists in the basic, practical know-how and best practices of exploration core logging and sampling.

Gemecs has also designed a basic coal quality understanding program for geologists. This course is aimed at geologists unfamiliar with coal qualities, and provides theoretical as well as practical training.
