    Saggy,

    15m @5% chalcopyrite - apart from being a useless "weasel word" type of description, is based on a visual estimate of the core. So in effect, it is 5% Chalco by area (estimated), which is extrapolated to 5% by volume for the full 3 dimensions of the core. It is convention not to report mineralisation by mineralogical area %. I can only assume this was done for reasons other than continuous disclosure regulations if you get my drift. There is nothing scientific or quantitative about the number presented. Please exercise extreme caution (skepticism) when dealing with this type of claim.

    Remember that chalcopyrite is CuFeS2 (1 part Cu, 1 part Iron, 2 parts Sulphur). Therfore, it is only ~33% Cu by weight, which brings the core grade down to ~1.5% Cu visually estimated (at ~500m depth, and seen only as secondary mineralisation this is utterly worthless).

    Cheers,
