Underground workings? I continually look at Line L5750N, and compare that info to the 43101 Figure 13-2 (C1 Vein Sampling)
I hope many have actually looked at this? If not, you should at least look. If nothing else, you have to find this interesting? What do you come up with?
Figure 13-2 on page 251, 2nd last page of the 43101, shows many of the historic samples, and the approx 11 of the 2010 verification samples. Look at those, and the results. Then go to Line L5750N, on page 90 (193), from approx the 1050 - 1250 mark. (that is where it seems this should line up, very close) Visually line that all up, look at all 3 images, and what do you come up with?
I am by no means not a Quantec expert, I only know what I've seen & read. But, look at these 2 pages, and compare.
Look back at the old NR for the C Veins (Sep 01, 09 & Dec 23, 09 & Sep 14, 06 & Nov 12, 09, etc)
This too, has to make you say, hmmm?
