30 Seconds of Info from Paul Blackney – resource estimation

This week's 30 Seconds of Info comes from Paul Blackney - Principal Consultant. Every step of the resource estimation process should be validated in some way: While this may sound onerous and time consuming, it doesn’t need to be. For instance, check the downhole compositing process by determining the total sample length before and after compositing – it should be the same or nearly the same. The cause of any difference should be determined and either corrected or understood before proceeding.

30 Seconds of Info from Ian Glacken – Capping before compositing or after?

This week's 30 Seconds of Info comes from Ian Glacken - Optiro's Director of Geology: Capping before or after compositing? This is a controversial topic which has adherents on both sides, although most believe that capping should be carried out after compositing, when the data has equal support. If you are going to cap before you composite the data, then the capping should be carried out with the variable as ‘metal’ or accumulation (grade times length), rather than just the assay itself.
