Technical Reporting
NI 43-101, JORC, and SK-1300 compliant technical reports. We specialize in thorough mining project evaluations for strong decision-making.
Geology and Resources
Geological modeling, resource estimation, and grade control services. We support your projects from exploration through production with data-driven geological analysis.
Our geologists work with your data to build reliable geological models, validate estimation methods, and deliver defensible resource statements.
Mine Engineering
Open pit and underground mine design, production planning, and operational support. From scoping studies to detailed engineering, using the same software we develop.
Automation & Digitalization
Digital twins, automated workflows, and data integration for mining operations. We connect your geological, planning, and production data into a unified system.
K-MINE guides mining companies through the study stage progression - explaining scope, accuracy, cost, and timeline differences between Preliminary Economic Assessment, Pre-Feasibility Study, and Definitive Feasibility Study deliverables.
Our team helps project developers understand what each study stage requires in terms of engineering detail, data density, cost estimation accuracy, and regulatory acceptance. We advise on optimal study sequencing to match project maturity with investor expectations and financing milestones.
