1. Survey and Geological Mapping
We provide reconnaissance to detailed-stage geological surveys and mapping to support mineral and coal/lignite exploration programs. Our work covers G4 to G1 level exploration, helping define geological conditions with greater accuracy.

2. Exploratory Drilling, Core Logging and Sampling/Analysis
We undertake drilling, i.e., core/non-core drilling, RC & suction drilling, detailed lithological logging, various type of sampling, all type of chemical analyses and petrographic studies for surface and subsurface investigations to establish the occurrence and characteristics of coal, lignite, and other mineral deposits, including their disposition, geometry, vertical and lateral continuity, and grade, supported by reliable subsurface interpretation.

3. Geological Data Generation and Interpretation
We collect, organize, and interpret geological data to build a complete understanding of the exploration area. This includes geological database preparation, seam correlation, structural analysis and Minex modelling/Surpac modelling and resource and grade estimation.

4. Geophysical Logging and Investigations
We conduct borehole geophysical logging using gamma, density, and resistivity methods. These investigations help interpret subsurface formations and strengthen geological modelling outcomes.
5. Resource Estimation and Geological Modelling
We develop geological resource estimates supported by 2D and 3D modelling. Our assessments also include grade evaluation and preparation of resource statements.

6. Geological Plans and Reports
We prepare professional geological maps, sections, lithologs, contour plans, seam folio and technical reports supported by annexures and compiled data. The Geological reports also included all the project documentation, Floor contour and structure contour plans.
