What We Do

Core Services

From first-pass exploration to production-stage grade control — GSA delivers geological and geotechnical capability at every stage of the mining cycle, without the overhead of a large firm.

Exploration

Remote field programmes, geological mapping, domaining, wireframing, and survey work — fully self-contained for projects anywhere in Queensland and beyond.

02 — Mining

Grade Control & Mine Geology

Production-stage grade control, domaining, wireframing, block modelling, and core logging — the day-to-day geological backbone of an operating mine.

Grade control — blast hole logging, ore/waste classification, dig limit design, reconciliation.
Domaining & wireframing — orebody domain definition and 3D wireframe modelling for resource and grade control purposes.
Block modelling — campaign and resource block modelling, domain assignment, estimation, JORC-compliant validation.
Core logging (geological) — diamond core logging to JORC Table 1 standard.
Database design, construction & QA/QC — setup and management of geological databases and QAQC programmes.
Blast movement — implementation and monitoring.
Procedural documentation / SOPs — grade control and core logging procedures.
Training — geology department onboarding and upskilling.
