SBT I was there twice last year (May and December). I was after buffalo tho here is what I have gathered.

In May while hunting buffalo we encountered a couple of tracks of solitary sable bulls, that we could follow if I was after one. In december I remember passing a couple of salt licks where we saw a lot of sable tracks and even stumble upon one.

All this refernig to upper area that was formerly leased by Chifuti's. Once we made a short stroll out of camp and came upon a huge herd of 30 with a couple of bulls - although Gordon is keeping those off the shooting list there are more herds in the lower area around the camp.
There was a GB client there before me in April on 21 day hunt. He got ele, buff, sable and leopard.
There was a US group of 3 hunters there in August - amongst other things they got 2 sables.
Further more - Gordon's area has improved so much that now even guys that hunt Park's area come and ask if they could hunt in his concesion.

If you wan't know more just ask Gordon directly and he will give you a honest reply.
