Aim, your fist sentence; "I as told by an employee of Quantec that it's a great minefinder in brownfield sites, but much less so on greenfield.", is correct in the sense that brownfield projects are categorized as such, because of the amount of historical data that is able to conjoin the geophysics.

In simpler terms, the Titan geophysics has less chance at finding a mine, if there is no surface work, nor work at depth done, hence, the greenfield definition. The green field definition evolves into the brown field, upon considerable surface work and the "at depth" complement.

A decision to use Quantec, or any geophysics in the same calibre, only comes upon reasonable evidence to employ. As for the Tesoro, evidence backs up, or justifies its use on the Tesoro. It is justified because of the many years of sampling and exploration work done on the Tesoro, which classes it as an "advanced project". If there had been no "underground" sampling or work, then perhaps it may have been acceptable to consider the Tesoro a green field project and not worthy of an in depth geophysical application.

Its because of the underground sampling that displays more facts about the Tesoro, for instance, but definitely not limited to; the increase in sulphides to depth, the established association of gold/sulphide content near surface and to depths around 100 meters. Also, is the extreme, which consists of veinlets intruding host rock that appear to be comprised of pure sulphidic metals which may or may not contain an efficient gold complement. Nevertheless, these micro veinlets are present and do intrude the host rock on the Tesoro, spreading a mineralized effect into the anomalies. If we take time to actually look at the size of 1 ounce of gold and compare it to the size of one ton of rock, we come to the conclusion that it is very very easy for one ton of rock to contain one ounce of gold, when veinlets millimeters, less than 1 cm in width, contain almost no hydrothermal fluids, such as quartz. The pure nature of the gold found on the Tesoro also evidents and supports any related data from the property.

If we look at this link provided, we will see how a centimeter cube of gold weighs around .6 ounces or 19 grams. If we look further, we see how an inch cube of gold, weighs about 10 ounces or about 315 grams. If we take the dimensions of a ton of rock, with comparable density to that which usually contains mineralization, we find something like 1m x 1m x ~18 inches. If you now think of a centimeter wide vein running through the entire meter of that ton of rock, and see how many cubed centimeters of gold could fit in there, it may suprise you. So what I am saying is , that one measly ounce per ton of gold disseminated throughout the ton, would not even be visible to the naked eye, and which is also, extremely high grade.

To tie this in with the geophysics, well the signatures seem to be picking up a constant mineralization through bigger consistent bodies, while underground sampling perhaps suggest the consistent grades in the C-1 area are not confined to the actual vein, but that there is a disseminated compliment of mineralization there as well. The historic data also helps establish this as fact and not theory.

Its because of the above and more, that no, the Tesoro is/was well worthy of a geophysics to the tune of what the Quantec offers and in fact required because of the advanced exploration results of samples and property/regional knowledge.

This part of your post;

"Someone told me that the ovoid anomoly is a granite intrusive, and whilst that is only hearsay, it could be. If you speak to a geologist he will confirm that many properties have a magnetic anomoly, but most of the time it does not turn out to be gold."

may not be readily justified had that person that suggested this to you, dug a little further into historical data. Had they dug further and clearly understood, I believe they would have had a much different perspective than what they have depicted in your above disclosure.

The historical data tells us that the host rock of the area appears to be mainly granodiorite with dioritic aspects. This rock , although perhaps granitic in nature to a small degree, goes through a different metamorphosis and should not be used as a lable or means for identification of the Tesoro host rock. Being fully open, I dont believe the person that told you this above, had access to all the property information and perhaps created an assumption.

I do agree that many properties have magnetic and electrical fieilds surrounding some sort of mineralization, however it should not be confused as to all ground having any appreciable electrical/magnetic field without a mineral complement to sustain the field. There is always a weak electric/magnetic/gravitational field with any singular rock in and on the ground, but when this rock is taken away, it disrupts those fields. And yes, properties will present characteristic magnetics and/or polarization and not have any gold, depending on the types of minerals present, this is why exploration work is done, to confirm the presence of what minerals and to what degree. But being frank, we can rule out the anomalies as having no gold, because the geophysics has already been proof tested on the property in many ways which Quantec themselves have documented into such proofs as the Z1-10 targets, and more.

We cannot ascertain if the anomalies have been drilled or not and where. The lack of information supplied to investors have us unable to come to a reasonable conclusion. Hole #8 would have been a fantastic determination, but apparently the bottom part of that hole that was initially released, turned out to be a mistake by management, and it appears now that the drill was stopped just short of drilling an anomaly in that area, which is weird.

Thank you for posting this, it gave me an opportunity to perhaps clarify a few misconceptions that some may have.
