Hi GG: Yes., Peter is correct in the tonnage implications on what is
known. In S. African diamond systems.., dykes and fissures are synomomous terms interchangeably used. Winspears terminology could be termed a dyke or a sill depending on the orientation of the deposit., I think Walt cleared up the differences in some previous posts., will have to look back to refresh., but Fissures or
dykes in S. Africa are as well accompanied by bulges where the magma swells thru the fractures in the parent rock. As well., small
pipes can accompany those dyke swarms as well., evidence the
small pipe near the Lando Dyke in Sierra Leone.
As I had once stated some time back in a conversation with Winspear., Randy Turner believe the slope of the defined dyke area
if extended to 186 anamoly would intersect kimberlite based on the
10 to 12 degree dip in the general area that the 100 plus meters of
kimberlite was intersected originally. If you will recall as well., that the
400meter step out hole intersected kimberlite at the EXPECTED depth. Are the 2 areas one., I dont know., but we know the area between the 4 drill holes in the S. Corner and 186 there have been
kimberlite intersections. and small kimberlite bodies.
Peter is on track with this deposit., the test will be the bulk sampling.
I would not begin to extrapolate the potential., but there could be
a wide swing depending on the propensity for large stones., and colors. Hope this helps gg.
Also the term dykes can be used whether it cuts thru a fault., etc.,
Walt had some references as well. in earlier posts.
Sincerely
