Sampling Program Design

Designing an effective sampling program requires careful planning and clear objectives. Program Objectives Define the purpose: - Reconnaissance rapid coverage - Resource definition systematic grid - Grade control high density, short turnaround Sample Density Factors affecting density: - Deposit geometry and continuity - Grade variability - Economic cut-off grades - Project stage Budgeting Cost components: - Field collection labor - Sample preparation cutting, crushing - Analytical costs - QA/QC samples add 10-15% - Shipping and logistics Documentation Create sampling protocols that specify: - Sample types and intervals - Collection procedures - QA/QC insertion rates - Chain of custody requirements

Verification resources

Cross-check terminology, classification, methods, and safety with these authoritative external resources.

  • Mineral Exploration Best Practice Guidelines — Canadian Institute of Mining, Metallurgy and Petroleum. Professional guidance for representative sampling, chain of custody, laboratories, security, and QA/QC.
  • National Instrument 43-101 — British Columbia Securities Commission. Canadian mineral-project disclosure requirements and related technical-report framework.
