Optiro has developed an internationally recognised system for the audit and evaluation of Ore Reserve estimates and the assessment of compliance to JORC, SOX and other international standards.

Reviews designed to improve sustainable financial outcomes for mining projects.

Risk assessment

We have developed an innovative format for audits which provides: a quantitative ranking against world’s best practice in over twenty key areas; a four-hundred point checklist for assessing compliance and operational performance; areas for improvement ranked according to the level of rectification required; and a comprehensive and yet compact summary document.
