Geological Modelling & Exploration Consulting

Geological Modelling & Exploration Consulting

Specialist geological modelling services for exploration companies, infrastructure projects, and anyone who needs to understand what’s beneath the surface.

James Horan has over 25 years of experience in geological investigation and modelling – from gold and base metals exploration in Australia and Papua New Guinea, to infrastructure and civil applications in New Zealand. He is an experienced user of Leapfrog 3D, the world’s most widely used implicit geological modelling software, and has delivered models and reports for clients ranging from listed exploration companies to local infrastructure projects.

Services

3D Geological Modelling

Implicit and explicit 3D geological models built in Leapfrog 3D, using drillhole, surface, and geophysical data. Suitable for resource estimation, infrastructure design, and technical reporting.

Drill Programme Design

Design and planning of drilling programmes for mineral exploration, geotechnical investigation, and resource definition. Includes collar layout, depth and spacing recommendations, and targeting rationale.

Block Modelling & Resource Estimation Support

Block model construction and grade estimation to support resource reporting. Experience across gold, base metals, and coal projects.

Topographic Data & Cross Sections

Topographic data sourced from LINZ and other authoritative datasets, integrated into geological models. Cross sections and long sections produced to client specification – including outputs suitable for NZX or ASX stock exchange reports.

Infrastructure & Civil Applications

Geological modelling for civil and infrastructure projects – including dam and reservoir design, slope stability input, and geotechnical investigation support. Previous projects include dam design for a snowmaking system and technical support for Canterbury-based exploration companies.

  • Junior and mid-tier exploration companies (NZX/ASX listed)
  • Mining and resource consultancies
  • Infrastructure and civil engineering firms
  • Local councils and regional authorities
  • Anyone needing a practical, experienced geologist
