SERVICE · A · ADVANCED GEOSCIENCE

Proving ground faster.

Satellite analytics, geophysics and machine-learning targeting that turn a wide licence area into a defensible drill decision — and a bankable resource.

THE HOW

Our Role and Solutions

Unlocking value at pre-production stage through Geo Science Services (and Project Originations).

The mining value chain from generative stage to sales, with Petrasys value proposition and two core roles
Where we sit in the value chain — advanced exploration service provider, and project pipeline builder and financing orchestrator.
A · GEOSCIENCE SERVICES

Eight services. One continuous case.

Each service stands on its own. Run in sequence, they build a single, auditable line of evidence from an unmapped belt to a bankable resource.

Prospect generation funnel narrowing an observed area of 200-300 square kilometres to a 10-15 square kilometre scoping target
From a 200–300 km² observed area to a 10–15 km² scoping target — each step narrowing the ground on converging evidence.
01

Project Due Diligence

Independent technical review before capital is committed — testing geological assumptions and checking resource work against the code it claims to follow.

02

Generative & Greenfield Exploration

Belt-scale interpretation and field geoscience narrow a wide licence area to a defensible set of targets.

03

Mine Geology & Brownfield Exploration

Pit mapping and grade control, stockpile discipline, reconciliation, and near-mine targets that extend life without new ground.

04

Resources & Reserves Estimation

Geostatistics applied by qualified persons and reported to national and international codes.

05

Metallurgy & Geometallurgy

Recovery, hardness and deleterious elements understood before they show up as a shortfall in the mill.

06

Drone LiDAR & Geophysics Survey

Aerial LiDAR and photogrammetry to centimetre accuracy, with magnetics, GPR, multispectral, hyperspectral and thermal payloads.

07

Big Data & AI-Based Target Generation

Models trained on regional datasets rank prospectivity across a whole belt and, just as usefully, say what is not worth drilling.

08

Digital Exploration & Mining Ecosystem

Connected systems built on real geological logic, so data collected in the field stays useful all the way through the operation.

A · DRILLING & SUBSURFACE INVESTIGATION

From exploration to engineering, our drilling and subsurface investigation capabilities turn subsurface uncertainty into reliable, decision-ready evidence.

Exploration stages from desktop study to resource definition, with key challenges and value offering at each stage
Desktop study to resource definition — the challenge at each stage, and the technology we bring to it.

From Potential to Proven Value.

Indonesia's next generation of world-class mining assets is already in the ground — waiting to be understood, developed, and operated.
