They currently know if they have drilled a hole with something highly significant intercept or drilled a hole with nothing significant in, its obvious to any field geologist, they will even have a good estimate of the grades they will receive from assaying. This information is highly sensitive.
It's in all of us shareholders interest to force their hand and reveal what they have intercepted BEFORE the options expire. If they have hit something spectacular, I guarantee they will not announce it before the options expire and we will lose out, they will be playing the game with these options.
You live in a dream world if you believe ASX and ASIC rules are strictly adhered to and I guarantee they will be spending their money on exploration, the reward of another DeGrussa at Wodger is too good to ignore.
