Services offering · Geology and mining engineering consulting
Scale up your projects using our resources: geologists, engineers and economists from the pit to the plant.
ACALA brings together experts from all facets of mining to help open pit and underground miners raise the efficiency and productivity of their operations. Our geologists, engineers and operations specialists use current technology and industry best practice to pinpoint challenges, close knowledge gaps and implement practical solutions. Thirteen services, one team, reporting to SNI, KCMI, JORC 2012, SAMREC and NI 43-101.
Why ACALA
Independent, technically grounded, and used to tight timelines.
By leveraging deep industry expertise, ACALA helps miners optimise their processes and achieve better results. Every aspect of the operation is considered, from the geology to the economics, so outcomes are streamlined and productive.
Independent by ownership
ACALA is independently owned with no equity in any project. Reviews, valuations and Competent Person reports are impartial, which is what banks, exchanges and investors require.
Great science, practical approach
From kriging to recoverable resource estimation with local uniform conditioning and simulation, using GEOVIA Surpac and 3DEXPERIENCE, always tempered with what works on site.
Multidisciplinary teams, fast
Geologists, engineers and economists mobilised to several sites concurrently and at short notice, so transactions and studies keep their timelines.
Thirteen services
Geology and mining engineering services
Each service has its own page with scope, method and examples.

04 · AssuranceDue Diligence and Project Reviews
Independent engineer reports, technical reviews for finance and M&A, risk assessments, technical audits, due diligence studies and litigation support.
05 · EngineeringOpen Pit Mine Design and Planning
Pit optimisation, cut-off strategy, economic depth and scale, life-of-mine plans and technical-economic models, transition studies, cost and productivity assessments.
06 · EngineeringUnderground Mine Design and Planning
Mining method selection, geotechnical characterisation, life-of-mine optimisation, drill and blast, ventilation, equipment and manpower, cost benchmarking, operational reviews.
07 · OperationsPlanning and Optimization
Geological models that sharpen near-mine targets, grade control and reconciliation; geotechnical and geometallurgical modelling; mapping campaigns, audits and site training.
08 · EconomicsMining Economics
Technical economic models and asset, project and property valuations at every stage, built on market data, benchmark indicators, site visits and project history.
09 · StudiesMining Studies
Scoping, pre-feasibility and feasibility studies, technical studies for resource and reserve reporting and regulatory compliance, project reviews and technical audits.
10 · ExplorationReconnaissance Survey
The first pass over ground nobody has measured yet: field mapping, sampling and target generation that decide where a drilling budget is worth spending.
11 · SurveyTopography Mapping
Detailed surface and subsurface maps with elevation, contours and geological features, delivered in the format your planning software reads.
12 · ReportingSNI/KCMI/JORC Standard Report
Auditable resource models reported to the code your stakeholders accept: SNI 4726-2019, KCMI and JORC 2012, with Competent Person sign-off.
13 · StudiesFeasibility Study
Geological, technical and economic work run together, so the decision to proceed rests on one consistent model of risk and return.
How an engagement runs
From the first data request to a report a bank can read.
Validate what exists
Every engagement starts with the data you already have and what it can support.
Data
- Laboratory assay reports, drilling methods, collar locations and downhole surveys validated.
- QAQC data assessed; sampling, assaying and reconciliation processes audited.
Gaps
- Gap analysis against the reporting code you will publish under.
- Fatal flaw analysis before a transaction moves forward.
Geology first, then numbers
Geology is considered throughout the resource process, not bolted on at the end.
Resource
- Domain interpretation, exploratory data analysis, variography, kriging neighbourhood analysis.
- Linear and non-linear estimation, simulation for risk, drill hole spacing analysis for classification.
Tools
- GEOVIA Surpac, Geoscience Referential Manager and Geology Modeler on 3DEXPERIENCE.
- Exploration databases organised so every number is traceable.
Design, schedule, value
Practical mine designs and schedules that allocate capital and resources efficiently.
Engineering
- Pit optimisation, cut-off grade and production rate strategy; underground method selection and ground support.
- Life-of-mine plans, transition studies, drill and blast, ventilation.
Economics
- Technical-economic models from scoping to feasibility.
- Capital and operating cost estimates from first principles and benchmarks.
Reports built for decisions
Balanced, focused documents for acquisitions, financing, listings and internal reviews.
Public reporting
- Competent Person, Qualified Person and Specialist reports under SNI, KCMI, JORC 2012, SAMREC and NI 43-101.
- Independent technical reports for stock exchanges, banks and private investors.
After the report
- Collaboration with your team so the knowledge stays in house.
- Site-based training on geology, grade control and planning software.
Software and people
The same tools we license, run by the people who train on them.
ACALA is the official GEOVIA reseller for Indonesia, so consulting, licences and training come from one team. Work delivered in Surpac, Whittle and MineSched stays usable in your own office afterwards.
