I didn't imply there was stripping at the underground (with no measured resource) niblack, so I have added that bit to the comparison for any readers who are not clear, see below.
The profitability of a property is dictated by the combined probabilities of what nature has deposited, and where the depost is; both on the map and in the bedrock.
a) The type and nature of the deposit will dictate the metal(s) present, the grade, the size, the metallurgy and any deleterious metals
b) The location/orientation of the ore body dicates infrastructure cost, business climate/stability, and stripping ratio, or undergoudn considerations.
The combination of these two sets of factors results in an overall indication of the economics of a project.
The niblack project's score with regard to the above criterias is very weak particularly with respect to measured resource. Almost three hundred holes have produced zero resource in the measured category. the odds af an economic mine at niblack are beyond remote with such a poor geological result.
This is why the fluff here needs to pump it has something to sell into. Proceeds are going into what fluff is bashing, namely CBS, because it scores very high on the criteria above with silver and moly, as I have posted earlier.
