Introduction:

Objective of Computer Aided Deposit Evaluation is to:

• Achieve enhanced knowledge of the deposit and ensure its optimum utilization.
• Ensure cost effective mining operations and raw mix design for effective production planning and extend deposit life.

Coverage:

The evaluation covers the following:

• Assessment of errors in estimates for various estimations of assay values.
• Preparation of isopleth and thickness maps for selected grades.
• Preparation of grade/ tonnage tables for mineral reserves.
• Preparation of block maps to depict the slice plans of quality.
• Undertake Quarry Scheduling and Optimization considering various parameters/ constraints to analyze their impact on mineral reserve, deposit life and economics of mining.
  

Methodology:

The following modular methodology is adopted in executing Computer Aided Deposit Evaluation (CADE):

Part I   :           Preparation of Drill Hole Data Base (DHDB)
Part II  :           Deposit Block Model (DBM)
Part III  :          Quarry Scheduling & Optimization

Benefits:

It helps an investor:

• Achieve enhanced knowledge of the deposit and ensure its optimum utilization.
• Ensure cost effective mining operations and raw mix design for effective production planning.
• Reduce drilling costs, conserve fuel, homogenize product quality and extend deposit life.
