I would say it is more likely that this is unclear in the talk. These numbers are the results of just XRT alone.

XRT yielded:
• A 22% mass yield inclusive of fines representing an overall 78% mass rejection;
and
• A 3.5-times upgrade to the gold grade

XRT followed by electromagnetic (EM) sensor yielded:
• A 61% mass yield inclusive of fines representing an overall 39% mass rejection;
• A 1.6-times upgrade to the gold grade;
• Ore sorter tail grade was 0.03g/t Au; and
• A 99.5% gold recovery was achieved into only 61% of the original mass.

By combining the two methods they are achieving 99.5% of the gold in final upgrade.
