RE:How Big?WWH,
The shear veins coming from Sigma can be seen in slide 28 of this old presentation.
https://www.integragold.com/i/pdf/2016-06-02-fig1.pdf
These have been drill from Sigma and there is at least one diagram that show at least 3 veins coming across the 500m space between Sigma and Lamaque. It's called the GRC target compilation. They have the historic data which were given to the GRC contestants. I believe it was under link
www.wsw.com/webcast/egf16/icg.v/presentationdownload.pdf
but unfortunately the presentation has been removed. (I only have a hrad copy of selected diagrams). They called them P shears in the historic Sigma, similar to the C zones prevalent to Triangle.
Now the pilot hole, drilled from the Lamaque side seemed to intesect those veins. Not sure if they collected and analyzed the cores from the pilot holes, but these days they have probably have a quick scan of the core sample to determine appromimately the gold contents with the hand-held analyzer. At least they should be able to determine the rock types, and if the shear zones (veins) are thick enough. From the illustration, they look thick (it's the pink on black diagram, pink is for the mineralized zones for Sigma(to 1800m) and Lamaque (to 1100m).
This means Lamaque Deep may not only contain stuff straight down below 1100m, but the deposit would bend toward Sigma filling the 500m gap between the two separate entities currently visualized for Sigma and Lamaque. In other words, there is a strong possibility that the two deposits joint together at depth, starting at around 1100m forming a mother of all deposits...May be, that's why George Salamis got all excited?
Hope that somebody got that presentation downloaded on their machines. Surely, that presentation must be archived somewhere at ICG. IR could perhaps help?
