That's my understanding on this topic as well.

As of 2016, the global average copper ore grades for copper mines was 0.62%. This represented a 25% decrease in the average ore grade in just 10 years. [source]. Estimating off the trend, and global grades are likely in the 0.5x % range currently.

A lot has changed in the previous 5 years. Without a doubt, the rapid electrification of the global economy as the world transitions to renewables is going to speed up the process of diminishing grades.

Where will we see global ore grades in another 5 years? In the low 0.5% range? Or perhaps even touching the 0.4% range?

Any additional tonnage to the reserves at 0.5% or above will have both a significant and positive impact on the life of mine.

In the mean time, we already have a significant and robust resource - 598.5kt at 1.51% for Nifty alone - ready to be early mine feedstock.

In 5 years time, when global grades are once again lower, CYM will be in a prime position to potentially launch the Maroochydore and Murchison mines, funded from operational cash flow. These sites have already proven to be well above current global grades.
