RE:RE:RE:RE:RE:RE:The Grid Chris refers to is 4000 X 500 so Depth is measured vertically from surface. In basic terms, thickness is the measurement of a tabular structure perpendicular to the plane it lies in, which works for pretty much any attitude, whether vertical, flat, or inclined. Width is sometimes used interchangeably with thickness. For instance, many drill tables report "true thickness" or "true width" of a mineralized vein when a drill hole intersects it at an angle. It usually comes down to understanding and following whatever convention the reporting company is using.
As for the 75m vertical spacing, you need to separate the two objectives. 1) The total depth of the "panel" of ore that GBR plans to define is 500m. 2) They have decided that to prove a resource, they need to have a vertical drill hole spacing of 75m i.e. drill hole intersecting/piercing the ore body "panel" every 75m below surface until they reach 500m. Since the horizontal spacing is 100m, it seems that they believe the horizontal predictability of grade and thickness is better than the vertical.

With regards to you wanting them to go deeper, they are doing that as written in the last news release......I underlined it.
"Great Bear is now undertaking a systematic grid drill program testing a 2.5 square kilometre “panel” of the LP Fault (5 kilometres horizontally by 500 metres vertically from surface). Drill spacing will initially average 100 metres along strike and 75 metres vertically. Additional drilling below 500 metres is also being undertaken."
So to confuse me even more, I don't understand the above paragraph. I get the horizontal 5 kilometres and take it that 500 metres vertically is depth. If they are doing that, then why in the very next sentence do they say they are going 75 metres vertically?
