. I recall looking over the drill core samples that SAN had on display. I guess their was a few meters of each of the Hinge, Cobina, 007 and L13. The L13 in particular had an blueish grey heavy streaking that appeared to be flowing through out the core. I gather that this was the result of the Ross River Pluton eruption as the magma flow filled the faults and cracks . I guess from doing Lab work we can follow the compositions of hydrothermal tourmalines are consistent with formation from this fluid at temperatures of 350 to 500°C, which are in line with temperatures from fluid inclusion microthermometry.... I guess once the drills hit the GoldenFairWay , then Bill F can follow these boron gases that left the tourmalin in the core after the cooling process....Long On The Golden FairWay Traps7
