Quality management is a system that integrates both quality assurance (QA) and quality control (QC) to deliver products and services that consistently meet requirements.
QA/QC is not just about sampling and assaying

Technical
Derisk staff have compiled a series of short technical notes covering a diverse range of topics relevant to the mineral industry. Please take a moment to browse through these notes and contact us if you would like more information.
Valuation risks of relying on Inferred Resources
Successful exploration programs reach a stage where there are substantial Inferred Mineral Resources.
Planning and organising effective site visits
Site visits to exploration prospects, mine development properties and operating mine sites can be a critical component of many project reviews, audits, technical studies, expert reports and operational support projects undertaken for a client.
How important is a pre-feasibility study?
The typical study sequence for mineral projects envisages three or four significant study levels as a project progresses from exploration to production:
Valuing operations with minimal Ore Reserves
Many mining projects, particularly narrow vein underground precious metals projects, have limited Ore Reserves defined at any time.
The future of site-based mining geologists
When will site-based mining geologists become redundant? And will the Coronavirus pandemic provide further incentive to fast-track a process that has already commenced?
Due diligence: How long is a piece of string?
Companies considering an option to purchase a mineral asset generally embark on some form of technical due diligence
The value and importance of geological database integrity
Exploration and mining companies have only one primary asset – what’s in the ground they own or have rights over. Consequently, the geological database is the cornerstone of a company’s most important asset.
