other burkina faso gold deposits, page-12

"It seems to me that where the other deposits are large continuous ore bodies the shear zone is a series of high concentrates ore bodies separated by ore-less rock. It’s the type of deposit that might lend itself to an underground "

Maybe contiguous maybe not with non continuous lodes along strike but as it hits out near surface I would have thought they would opencut it initially, then maybe put a portal and drive say say starting from 50 metres at the base of the opencut mine to underground mine the dyke.
It would save on around 400metres of drive development from surface.
Some of those grades close to surface are high enough for DSO ore just opencut mine it and ship it back to Australia or timbuktu to process (around $5000 a ton value in ore) never been done before I guess and it would seem over the top compared with putting in a plant on site but shows how high tenor the ground is.
Love to see some met tests on the ore ie is it oxide and easy to treat or is it refractory ?
