Low grade big tonnage versus high grade low tonnage – both are important and both potentially highly valuable. As a rule-of-thumb many geos look at gram metres as to whether or not a drill result is interesting. Simply put, this is the grade multiplied by the width. A vein that is 5 metres wide and averages 60 g/t will represent 300 gram-metres, but so will a zone that is of lower grade, say 100 metres wide, grading 3 g/t. It of course would depend on the geological context as to which is the more interesting drill hole, but any exploration manager would be ecstatic to receive either result! An intersection of 10 gram-metres may or may not make it. An intersection of 50 gram-metres is pretty good; of 100 or 200 gram-metres is pretty gosh darn good, and anything higher becomes exceptional.

I hope Oromin will add to the presentation gram metre maps for Golouma West, Kerekounda, Kourouloulou and Golouma South.
