Can always ask GT, but I do wonder what it is that people honestly believe they will benefit from doing so, along with constant sectionals, other than to address a personal niggle like the sectionals have proven to be? Zeff is drilling across strike, or has been for the most part.. Some drills are reporting up to 10 separate zones (by that I mean significant grades above reported economical cutoff)
You can see why as the deposit is a series of minerlised lenses from surface to circa 300m deep in a body of altered tonalite. CDE I wager through a number of drills down along the cross cutting strikes and returned good numbers.
But good numbers in a thin corridor does not a low grade bulk tonnage mine make..
In the end it will be like Fort Knox below where the pluton is cross cut with a series of fractures which happened on cooling.. A higher grade centre with the rest as infused granite...
There is no real lode type structure to this arrangement, ergo the benefit in a typical long section is mute to a degree. 8teyThe Fort Knox gold is hosted by a late-Cretaceousgranitepluton that intruded into the surrounding Fairbanks Schist.[6] The pluton is described as "a light gray, fine grained granodiorite, medium grained biotite granite, and coarse grained, biotite granite porphyry, which form blocky bedrock exposures".[6] Gold, bismuth and tellurium minerals occur in pegmatite and quartz veins and fractures within the pluton.[6] The sulfide content is very low (<0.1%).[6]
The Fort Knox gold deposit had pre-production Proven and Probable Reserves in 1996 of 158.3 million tonnes @ 0.83 g/t gold with a 0.39 g/t gold cut-off for 4.2 million ounces.[7] After the production of over 7.5 million ounces, at 31 December 2019 Proven and Probable Reserves were 255.8 million tonnes @ 0.3 g/t gold for 2.80 million ounces.[8]
