For people who are knowledgeable in the reporting and stages...

For people who are knowledgeable in the reporting and stages that will follow, what information in the announcement could we expect if everything is positive considering that it is only an exploratory drill?. What process would you use to value this before they actually get around to measuring what's in the ground with follow up drilling? Would the estimates they have given be similar to an inferred amount like in mining? One last one, how expensive will the follow on drilling be to find out how much is in the ground?

Thanks
