Aggregates & Minerals Exploration

Fast, Efficient Assessment Of Your Potential Yield - For New Site Extraction, and Old Site Extension

Geophysical Surveys

If you are looking to buy or lease new land for aggregates or mineral extraction, a non-destructive non-intrusive preliminary survey is an excellent starting point to make a purchase decision and negotiate costs with the current landowner.

Geophysical surveys are a fast and efficient tool for assessing the aggregate and mineral resource potential of a site, and identify specific areas for geotechnical exploration.

Minerex Geophysics primary exploration work is in the aggregates industry. We work with quarrying firms to assess their sites for:

  • Extent, Depth, Volume and Resource/Tonnage Weight Calculation of deposits for commercial viability
  • Overburden thickness and depth to extractable rock
  • Rock types and quality
  • Examination of subsurface faults, fracture lines and Karst zones
  • Determine Continuity of rock type/presence of discontinuities
  • Groundwater resources and conditions
  • Slope stability for access design

By measuring and examining regional geophysical and satellite data, then creating reports on target areas, a geophysical survey can investigate the commercial viability of an undeveloped site, or the extension potential of an old site - without the need to mobilise ground crews and heavy plant at a preliminary stage.

  • Different rock and mineral types have different geophysical responses, and their subsurface distribution is studied using electrical, gravity and magnetic survey techniques.
  • Ireland is rich in many mineral deposits - The Department of Communications, Marine and Natural Resources has created a very informative guide to The “TOP 55” Deposits.
  • Aggregates - stone, gravel, sand and clay - are not considered as minerals, but are still regulated in Ireland by planning and environmental laws.
  • When a mineral or commercial aggregate deposit is found, there can be a flurry of excitement - but before any mining works can start a detailed program of investigation and preliminary works is essential.
  • A geophysical survey is a perfect starting point to plan a drilling schedule to extract samples from under the ground. Data sets from geophysics and drilling activities are then combined to produce more detailed maps and diagrams to inform development of the extraction plan.

Effective Exploration Programmes

This pyramid diagram shows the typical progress of an exploration programme.

Thousands of mineral prospecting licenses have been issued in Ireland, but most will not progress beyond the environmental investigation stage, because many promising finds turn out to be unsuitable for long-term commercial exploitation

Minerex Geophysics have worked at mining and aggregate quarrying sites across Ireland, and have a deep understanding of the types of issues faced by mining, construction and engineering companies at these types of sites, including:

  • Safety
  • Commercial viability
  • End-of-life extension potential
  • Water contamination risks
  • Environmental pollution risks

Minerex Geophysics

Bringing Minerex Geophysics on board as your trusted geophysical consultants early in any new planning process can help you build up a better picture of exactly what is going on at and below your project site - saving your company from wasting time, labour, cash and plant resources.
