With the first drill holes in the mineralisation (I typed too fast yesterday... at this point it is only mineralisation and not yet a resource) the target has been confirmed. At this stage of the process as long as the grade is within the typical economic limits for the mineral in question no further economic evaluation is yet relevant.
It has been said that estimating a resource is akin to solving a jigsaw puzzle which shows a polar bear in a snow storm... but you only have three pieces. At the early stage you are describing the geologists only have one piece of the puzzle...
So the answer is no. Any estimate of the total mineralised zone at this stage can only be a range not a figure (and it would be an extremely broad range).
