Comprehensive Solutions for Mining Operations
Metal Accounting Automation
Our flagship offering. We design, build, and automate complete metal accounting systems that align to AMIRA P754, reduce manual reporting, improve data accuracy and consistency, detect anomalies early, provide management dashboards, and save time while reducing human error.
Metal Accounting Audits
Independent reviews of your current system, including gap analysis against AMIRA P754, mass balance validation, stream sampling & measurement assessments, data accuracy & reconciliation checks, and practical improvement recommendations.
Dashboard Development & Reporting Automation
We build clear, visual performance dashboards for daily production, metallurgical KPIs, plant downtime, recovery & efficiency trends, mass balances, and management summaries. All dashboards are designed to be easy to understand, actionable, mobile-friendly, and integrated with existing plant systems.
Advanced Analytics
Unlock deeper insights with forecasting & predictive models, throughput & recovery optimization, anomaly detection, circuit diagnostics, scenario modelling, and data quality assessments.
Training & Skills Development
Empowering your team is part of our mission. Training includes metal accounting fundamentals, mass balancing and reconciliations, sampling & measurement best practice, dashboard interpretation, data quality management, and hands-on analytics coaching. We train operators, foremen, supervisors, and metallurgists.
Ongoing Monthly Analytics Support
Continuous support for teams that need troubleshooting, monthly reporting assistance, system maintenance, dashboard updates, data investigations, and regular improvement recommendations.
