28 October GML says "the presence of chalcopyrite throughout large sulphide intersections confirms the
Company’s opinion that there are very significant copper systems throughout the tenement package"

Then when the assays come out on the "large sulphide intersections":

GRC260 - 14m @ 0.93% Cu & 2.24g/t Ag from 81m
GRC278 – 35m @ 0.18% Cu, 0.11% Zn and 3.07g/t Ag from 125m
GRC279 – 25m @ 0.15% Cu, 0.15% Zn and 3.35g/t Ag from 160m
GRC280 – 20m @ 0.51% Cu & 13.77g/t Ag from 70m
GRC281 – 25m @ 0.25% Cu & 3.75g/t Ag from 185m
GRC282 – 15m @ 0.24% Cu & 3.08g/t Ag from 85m

I think they built up expectations way too high. Obviously they are very good at spotting chalcopyrite, not so good at estimating economic concentrations of same.
