RE:Kevin at it again..cdnrock,
This picture is nice, since we can draw some information out of it. A cropped picture may look pretty, but useful information such as the worker's boot may be cropped out , so we would end up having nothing to compare the sample with.
- There is an unintended/intended scale in the picture for us to size up the sample. It was not a ball-point pen this time, but a computer keyboard in the background would be good enough for comparison purposes,... The longest key is about 5cm long.
What we really need is
the date this rock was picked up. Does anyone know? Kevin should.
- So, this rock is approximately (very rough estimate) 14cm x 14 x 8cm thick x 2.6 = 4070 g @10%Au = 407gAu = 13 oz Au x 1700 = $22k (say roughly $20k rock...This is just for
the right tip of the whole rock, the part that contains the "pure gold" in quartz.
- As you move to the left side of the rock, there seems to be visible gold in the grey sedimentary rock as well. They are in small cracks (mm size) which are more abundant in the middle portion compared to the extreme right. This make sense, since the major puking site is located in the quartz area, but the thermofluid would try to squeeze in whatever cracks, crevices available in any rock (sedimentary included). But the quartz zone (gold draping over the quartz, and filling the cracks in quartz crsytals) seems to contain better catalysts: lowest pressure due to the stretching in the shear zone, or the presence of some kind of chemical compound, e.g. iron magnesium??? (chemimistry is not my forte, so weigh in if you are a geo-chemist).
- For a macro-economic consideration, let's ignore the finer gold on the left side of the rock, which could amount to several gpt, but why bother if the right side contain Au @ much higher grade (in %, noting that 1% = 10,000 gpt...please check my conversion).
