Site connectivity
Intermittent or high-latency links require designs that degrade predictably rather than fail.
Extraction and resource operations
Mining
Mining operations run distributed sites with constrained connectivity, industrial control systems, and safety obligations. Technology change must respect operational technology boundaries and remote support realities.
Business challenges
What makes change difficult in this sector
OT and IT separation
Control systems require deliberate boundaries and monitored crossing points.
Workforce mobility
Rotational and contractor workforces create rapid identity lifecycle change.
Safety and reporting
Operational and environmental reporting obligations depend on data that is often locally held.
Architecture principles
Decisions we hold constant
- Site operations continue when the link to the centre does not
- OT boundaries are monitored crossings, not implicit trust
- Identity lifecycle is automated for rotational workforces
- Operational data is collected once and reused
Governance considerations
- Documented OT change control separate from IT change control
- Remote access to control environments brokered and recorded
- Environmental and safety reporting data lineage documented
- Contractor access expiry enforced by default
Transformation phases
A sequence that protects service while it changes
Site and control-system baseline
Document site architecture, control system boundaries, and existing remote access paths.
Boundary and access control
Introduce brokered remote access and monitored OT boundaries.
Data consolidation
Establish reliable collection from sites into a governed analytics platform.
Operations handover
Transfer monitoring and access administration with site-level procedures.
Technology alignment
Where platform capability supports the approach
Identity
Microsoft Entra ID with automated joiner-mover-leaver processes for rotational staff.
Edge and cloud
Azure services with edge-tolerant data collection patterns.
Data
Microsoft Fabric for consolidated operational and environmental reporting.
Security
Microsoft Defender and Sentinel for boundary monitoring and detection.
