Your point was that they sampled 1.96m (7x 0.28m). The samples were taken perpendicular to the vein. i.e they sampled the average width of the vein (0.28m) every 4.75m (just to make you happy as it "wasn't 5m") for a 28.5m intersection. They have provided the average grade and channel width over the 7 samples along that intersection length and extrapolated that will be what the vein contains on average. I don't really think it is that hard to understand

What you are suggesting by claiming that is false is that they selectively picked 7 mineralised intersections and the 4.75m between each spot was lower grade or barren. Pretty big call if you ask me.

And yes they said that 44% of the samples had >3g/t cutoff which is what they have obviously used as their guide of economical. That also wasn't that hard to understand. It's clearly in the heading. It also gives a weighted grade of almost 6g/t + an ounce of silver which should be economical for an underground operation. They only need 16kozEq to pay back start up cost + allow for an AISC at c. USD$700/oz.
