Ann: Fourth Quarter Activity & Cashflow Report, page-2

Very interesting paragraph taken from the Quarterly ann.....

Measurements carried out on core samples of the massive chalcopyrite from hole TRBDD09 revealed that the actual EM response for that rock is only about 10% of the theoretical response that might be expected from material grading 28% Cu (approximately 80% chalcopyrite). The probable reason is that the mineral grains are separated by “gangue” and so are not physically in contact with each other, inhibiting the rock’s ability to conduct an electrical current and so rendering DHEM surveys much less effective than in other circumstances.

....these guys could just be scratching the surface in regard to what could potentially lay beneath!
