In an effort to put the Pillars assay results in perspective I've converted the numbers to grade times width to get a frequently used quantity on inclined long section displays with units of gram*meters :

Earlier this year ( Jan 22) our neighbour Kodiak released the following information about one of their recently completed drill programs:
Almost 1/3 (30.4%) of the 217 drill holes in the central Golden Mile returned greater than 7 gram*metres of gold mineralization, and 37 of those drill holes returned greater than 10gram*metres of gold mineralization, a high grade “hit ratio” of 17%, or approximately 1 in 5 holes;
If I've read the Sage press release correctly then 26 holes were drilled at Pillars with results from 8 of those holes still outstanding. That leaves the 5 reported above plus another 13 which presumably were barren. Using Kodiak's definitions I calculate 5/18 holes greater than 7 gm*m or 28 % and 4/18 greater than 10 gm*m or a 22 % high grade well hit ratio. The numbers appear to be very similar with Kodiak's results and should be viewed as encouraging in my opinion. We shouldn't expect bonanza grades with every drill program. Please check my math and let me know if you see any discrepancies.
