Geological
Investigations

Geological mapping is the basis for all geological interpretations and allows for predictions to be made.

Geological field mapping

Geological mapping forms the foundation on which all other geological data and geological interpretations are built.

Geochemical sampling

MINROM will test the grade of a sample at a specific location for a number of elements or compounds.

Geophysical surveys

Geophysics makes use of the physical properties of the Earth in order to understand and interpret the subsurface geology without using invasive methods.

Metallurgical sampling

Metallurgical samples are commonly extracted as a bulk sample with the aim of getting enough material to accurately represent the deposit or a lithological portion of the deposit.

Drilling

Once target areas have been identified from the mapping data then drill holes can be planned.

Geological Field Mapping

The most basic way of obtaining geological information is through geological mapping. This may sound simple enough, but it is the primary way geological data is obtained and is especially important in the initial stages of a project. Geological mapping forms the foundation on which all other geological data and geological interpretations are built. The better the geological mapping data, the better the interpretations and the overall project understanding.

A famous quote in mining is “the orebody dictates”, meaning that we can’t tell the Earth what we want to be there, but instead, we need to listen when it tells us what is actually there. Geological mapping is one way we listen.

Geological Surveys

Geophysics makes use of the physical properties of the Earth in order to understand and interpret the subsurface geology without using invasive methods (i.e. pitting, trenching or drilling). Geophysical techniques and applications to finding all sorts of elements and commodities have grown dramatically in the last few years. It is important to match the type of geophysical survey with the mineralisation and surrounding country rock before deciding on a survey method. This is where geological expertise can really save a lot of money and help get excellent project data. Occasionally, two or three surveys might be required in tandem to identify true anomalies.

MINROM can assist you with the following types of geophysical surveys:

  • Seismic surveys
  • Ground penetrating radar (GPR)
  • Magnetic surveys (Mag)
  • Radiometric surveys
  • Gravity surveys
  • Induced polarity (IP) surveys
  • Electromagnetic (EM) surveys

Drilling

Drilling is probably the second most powerful tool in a geologist’s arsenal, the first being geological mapping. Once target areas have been identified from the mapping data, then drill holes can be planned. The aim of drilling is to obtain material from known intersections and depths below the surface so that interpretations of the geology can be made and samples of the mineralisation can be collected.

The type of drilling performed plays a big role in what data can be collected, the method of collection, and the planning of the drill holes in order to maximise the amount of data obtained. The following drilling methods are commonly used:

  • Diamond drilling / Core drilling
  • Reverse circulation drilling (RC drilling)
  • Percussion drilling
  • Percussion rotary air blast drilling (RAB) – widely used in Australia, but not Africa
  • Sonic (vibratory) drilling
  • Auger drilling

With MINROM’s assistance, you can be confident that your mineral resources will be accurately assessed and evaluated.
