Ann: Drilling Commences on Manganese Discovery at Korhogo Project, page-11

I did a quick calculation on the manganese potential.

Looking at the map, the outcrop appears to be 14km long and on average 200 metres wide (It may be wider underground). Assuming the average ore thickness is only 10 metres (the drilling goes down to 50 metres), and if the average density of the ore is 5 times (manganese is a dense ore), we get:

14,000*200*10*5 = 140 million tonnes of ore. At 20% manganese, it's 28 million tonnes of manganese.

For a comparison, E25 has 263 million tonnes of ore at 10% manganese (26 million tonnes of manganese). They have a market cap of 122 million.
