Keep in mind, the opinions on this site are for the most part speculation and are not necessarily the opinions of the company WITHOUT PREJUDICE
We are all interested in the big anomaly that measures a bit over a mile x a bit under a mile and .74 of a mile thick. The Titan survey in reference to this is not easy to understand and at first glance measuring an electrical phenomenon in degrees of a circle seemed odd, at least to me. Reviewing the Quantec calculations, not being well versed in all three of physics, mathematics and geology gives me difficulty in following the highly mathematical examples Quantec gives. Regarding induced polarization etc they explain that the alternating current phase differences have to be measured in square wave volts (not amps) and show the tangential line angle differences between phase vs. chargeability between full decay and last half decay. It is this change in the slope that measures the milliradians (one thousand of one degree of a circle) that we are interested in. I came across an article with some excellent diagrams etc. and I found some of it easier to understand than Quantec. “Application of Geophysical Inversion in Mineral Exploration” is the title. The link is at the bottom.
This paper may help an understanding of how geologists interpret the figures and is partly in answer to some questions that have been raised in the past that have been answered by Sculpin & Hog etc in earlier posts, re why we should be comfortable with the Titan survey, and in my own case why I only bought a few shares initially and as I kept learning why I kept adding throughout the last 14 months, especially after the second survey.
If you are short of time, start at page 6, and on page 13 they again state that gold values are directly linked to sulphide concentration, and on page 15, using the Mt. Milligan mine, (just northwest of Prince George) example they demonstrate that the error is only 5%. (Incidentally MBX = magnetite brecca type of rock formation). On the next page the IP cut shows the gold concentration of this mixed but mainly copper deposit. I hope I don’t waste your time but I found it interesting and perhaps someone else might also.
p.s. Could I put my name in for the drill results for Sept. 5th?
