    Thanks for the table. Just one comment though, the cobalt concentrations are a bit out-dated for the current boom in battery demand. Those levels are appropriate for sulfide deposits where dissolved cobalt and other minerals may accumulate. For example, AML and CZN have recently reported levels that seem to fit your table. (Also, the Congo has large deposits which fall into this category). But these types of deposits are becoming harder to find, and so in recent times the soils from ultramfic rocks are becoming the next mining opportunity. These deposits tend to be bigger but with levels of cobalt that are lower, so a range of 0.1% is acceptable for mining if there is a large resource. For example, CLQ and ARL are two well-known companies preparing to mine with levels of about 0.1%.
