Victor, Here is one of the Ann's that CLA has put out to comment on extraction.
Ann: Excellent Cobalt Leach Extraction and Improved Flotation
We really only have Company Ann's to work off, I imagine it is the same for most investments, unless you are an industrial chemist with some insider knowledge of the exact situation.
What we do know is that there is a strip of Dolomite ore that runs for pretty much the full 100km length of the CLA tenement, with fairly consistent Cobalt grade for what appears to be it's length. The prior company that had possession of this land had done drilling looking for Copper, but it was only reasonable grade, better prospects elsewhere. Cobalt was at a much lower price back then, and of little interest.
So today, we know that Cobalt is worth a hell of a lot more and it resides on the DOF that runs from surface to +400m deep. It is also of a mineralogy that makes it one of the cheapest to extract in the world. This Capex/Opex saving is the kicker.
Having a 'reasonable' amount of Copper mixed in is just a little bonus, Slab money for xmas.
Sound good so far?
Once the Feasibility study comes in, we will have some figures to wrap around what seems like a pretty obvious play.
If you spend some time digging through older reports rather, including some from KNE, you may just find that there are other Minerals on other various locations of the tenement (It's a large one). Celsius isn't focusing on those these days, Cobalt harvesting seems to be their game to date.
There are obviously other companies/sites that have greater Cobalt yields, 5%+ from some that I hear about, and I'm sure they will also do well. I cant imagine one Cobalt source providing enough for the entire global market.
I do however have a feeling this one will do well (extremely well) based on the simple facts of it's availability, mineralogy, surrounding infrastructure, management and locale.
Best wishes on your life choices.
