This is not drilling lingo.. it is mineralogy. This is a ‘core’ drilling result where they drill into the earth and pull up a core sample to find out what it is made out of, and it it is worth the effort to mine.

TREO = Total Rare Earth Oxide

These would be compounds like:

Ce2O3 = Cerium Oxide
Er2O3 = Erbium Oxide
Eu2O3 = Europium Oxide
Dy2O3 = Dysprosium Oxide
Gd2O3 = Gadolinium Oxide
Ho2O3 = Holmium Oxide
La2O3 = Lanthanum Oxide
Lu2O3 = Lutetium Oxide
Nd2O3 = Neodymium Oxide
Pr2O3 = Praseodymium Oxide
Sm2O3 = Samarium Oxide
Tb2O3 = Terbium Oxide
Tm2O3 = Thulium Oxide
Y2O3 = Yttrium Oxide
Yb2O3 = Ytterbium Oxide

These rare earth compounds are often used in optical coating, rare earth magnets, lasers/laser diodes, MRIs, and semi-conductors just to list a few.

It would be interesting to know what the exact Rare Earth concentrations were when broken down to actual elements. The Rare Earth elements have different values depending upon which one they are.

Carbonatite = assumed to be formed when magma moves through a limestone structure, partially melting it. It has to occur in a oxygen-less environment because Calcium and Carbon react violently with oxygen when they get hot enough, with the Carbon going to Carbon monoxide or Carbon dioxide gasses. They mentioned something about igneous over sedimentary in part of the report – this could create carbonatite like structures.

One thing that concerns me is that they throw ‘gold’ in on the mineralization report. (Our interest in Bull Hill NW is also piqued by the intercept of significant gold mineralization in drill hole RES10-60, where the highest grade (12 ft @ 11.85 gpt Au) is contained within a silicocarbonatite dike.). This is a small sample size, seen in only one hole. Considering the worth of the other Rare Earth compounds and that it was only found in one hole.. it would not be worth mentioning. “GPT” means grams per ton. (453.59 grams = 1 pound, 28.35grams per ounce – more than 2 tons of ore would have to be crushed and processed to get 1 ounce of gold).

Table 1,2,3 are interesting.. I would need to take time to plot it out. I need more info on the map locations of the holes and topology of the area. This would give me the underlying geological structure.

Wikipedia has a second on core drilling..

http://en.wikipedia.org/wiki/Exploration_diamond_drilling

Might give you an idea of what they were doing. There was a map of where the drill cores were done and I don’t like the layout/pattern of cores. Normally you try a ‘matrix’ of cores to try to find the edges. I the referenced core results showed that some of the samples were taken right next to each other and most of them were in a single line (actually two closely spaced lines).. not a matrix. It was almost like they didn’t want to find a core that disagreed with their premise of wealth under the ground.

Found info that cost per foot of exploratory drilling averaged $2.16 in 1994. (Encyclopedia of Chemical Processing and Design, pg 20 under surface drilling, exploratory). Lets double it for current price (overestimating). Most of those exploratory holes that REE ran only go down less than 100 feet. Cost would not be a driving factor since that would be a $500 core for 100 feet of depth – not including assay cost. Most of the drilling cost is in getting/setting up the rig. If they run multiple holes, volume makes it cost less. Some of the rigs are also tractor/bulldozer structured – so road access is not an issue. Looks at this, their pattern of holes and depth make me very suspicious (all near each other, all along/near the road).

Example of tractor/crawler rig:
