    no, i was saying, (asssuming a grade), companies need to assess how big a deposit needs to be to become minable for a certain depth and adjust their drill spacing to suit. for example if you have a supergene intersection of 7m at 66g at a depth of 35m you dont need it to be 50m x 50m laterally (and you'd be mad to think that is even possible), you would only need an ore block 7m x 10m x 10m to have a mine, so close up the drilling spacing to 5m in all directions away from your original hole.

    in regard to the numbers quoted above...the jokes on me...because, looking at the quantities in more detail, an ore block of 11m x 50m x 50m would produce 63,000t ore valued at $30,000,000 while costs would be about $10million...but getting back what you could reasonably expect of an ore body there, they have already assumed the supergene zone runs from east to west, ie is linear, and is therefore not likely to be wider than 17m or about one third of the numbers above, producing less than $10mill worth of gold, which could be marginal.

    i looked at this prospect in detail years ago when i was considering plainting it for lack of work by tmb (remember it is already 4 years into an 8 year term and they haven't drilled a single hole),
