Ann: Commencement of Diamond Drilling - Okavango Copper Project, page-70

In 2019, the first harvest of 3,700 pounds of copper cathode (32 sheets x 117 pounds) was made at Florence Copper. The copper sheets produced were assayed at more than 99.9% pure copper.PTF operations at Florence Copper successfully demonstrated Taseko’s ability to produce high-quality copper cathode within the stringent environmental guidelines of federal and state permits. It also informed the positive economic projections for the project.

As for CBE only my opinion here:
No technical comment has been posted on the latest ISCR report, this suggest to be that the broader investors are not fully aware of the process, a cathode picture like what is displayed above is not coming atm, Investors can check the Tesco mine time line pilot plant.
It is a journey and management's cautious approach here is paying dividend, so far they are on the right track.
