Services · Geology and mining engineering consulting in Indonesia
Thirteen consulting services, one independent team, reports that banks, exchanges and regulators accept.
ACALA’s geologists, engineers and economists work from exploration to closure: exploration programs, resource estimates, mine design and planning, valuations, due diligence, economics and studies. Independent by ownership, reporting under SNI, KCMI, JORC 2012, SAMREC and NI 43-101, and delivered in the same GEOVIA software your own team runs.

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 and site visits.
09 · StudiesMining Studies
Scoping, pre-feasibility and feasibility studies, technical studies for resource and reserve reporting and regulatory compliance, reviews and 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.
