Ore Reserve Reporting

Ore Reserve Reporting

The JORC (2012) reporting code describes an ore reserve as “the economically mineable part of a measured and/or indicated mineral resource”. It includes diluting materials and allowances for losses that can occur when the material is mined or extracted. It’s defined by pre-feasibility or feasibility studies that include modifying factors, and demonstrate that extraction could reasonably be justified at the time of reporting.

Following the guidelines for competency and transparency adopted by the internationally recognised reporting codes JORC Code (2012), CIM Definition Standards (2005), SAMREC Code (2007) and SME Guide (2007), we have the in-house expertise to cover the modifying factors needing to be investigated to a pre  or feasibility study level.

Our expertise includes hydrogeology and hydrology, geotechnical, mine design and scheduling, mineral processing testwork and flowsheet development, tailings storage, environment and social impact, and economic evaluation and financial analysis.

We write compliant technical reports to support equity market filings on the major international stock exchanges including competent person’s reports, mineral expert’s reports and national instrument 43-101 technical reports. We also prepare mineral resource and ore reserve estimates reports for listed companies for their annual information forms.
