Yes, exploration and discovery of new deposits continues. Everything else remaining constant, the 88M tonnes (99M tonnes in the latest USGS report in [3]) will need to go up by orders of magnitude to get the 25% to 100% (if that is ever the goal).
The US went from 700,000 to over 12,000,000 from the 90s to today. In places where we've actually really started to look, we've found orders of magnitude more. I wonder how much more we'll find when we actually go looking for it elsewhere.
