Frankly, I do not really understand, page-49

Actually good pick-up... when I went to look up density for dolomite again I realised I picked up the wrong number... my mistake... just to clarify I'm not a geo... resource estimation is a lot more complicated than what I've done in this table... but effectively it's about working out the volume initially and multiplying the volume and the specific gravity OR density. This then gives you the volume of resource in tonnes:

Here's the updated table, I've increased the density or specific gravity to 2.87gm/cc and the link below explains it.

	Column 1	Column 2	Column 3	Column 4	Column 5	Column 6	Column 7	Column 8	Column 9	Column 10
0	Scenario	Length (m)	Average Width (m) - Lower End	Average Width (m) - Upper End	Average Depth (m)	Volume (m3) - Lower End	Volume (m3) - Upper End	Density	Resource Estimate (t) - Lower End	Resource Estimate (t) - Upper End
1	Single DOF depth to 150m	11000	4	5.5	150	6,600,000	9,075,000	2.87	18,942,000	26,045,250
2	Single DOF depth to 200m	11000	4	5.5	200	8,800,000	12,100,000	2.87	25,256,000	34,727,000
3	Single DOF depth to 250m	11000	4	5.5	250	11,000,000	15,125,000	2.87	31,570,000	43,408,750
4	Single DOF depth to 300m	11000	4	5.5	300	13,200,000	18,150,000	2.87	37,884,000	52,090,500
5	Single DOF depth to 350m	11000	4	5.5	350	15,400,000	21,175,000	2.87	44,198,000	60,772,250

Hope this makes sense.

And @bratty, whilst CLA will have a lot of contained cobalt in the ground which will indeed be valued over $3-$4B, the company only gets valued at a fraction of this due to the cost involved with getting this out and making it into a marketable product.
