The zimmi area is south and east of BO. I had in the past pulled up some good maps and started doing the same thing you are talking about.
I have sent emails to the minister of mines for SL inquiring about SGCP's standing with the GOSL, but with no response. They may only have one computer for many GOSL agencies. I have not yet tried to snail mail them.
The US embassy and the CIA have decent maps of SL. A worthy project to map out all of our active and non active properties, but one that I put aside for personal time reasons.
I think finding a good Geosurvey map would be a great find, I beleive the sewa and zimmi areas have historically been good places for Diamonds.
At some point in the future we will find significant diamond loads, just a matter of time and equipment.
Good luck let me know what you discover.
