Ann: Wide interval of visible gold in drilling at El Zorro, page-94

Good pick up on that H8. I've done some rough calcs to get an idea of what grades we could be expecting for 51.

Diameter of the visible gold chips are ~0.5mm. Calculating as a sphere we get a volume of 0.065mm3 and weight of 0.00124g for 1 gold chip.



Then to calculate concentration per 1kg sample


Drill core diameter according to pics provided and some googling is 6.35 cm. Gives a sample weight of 2kg for 25 cm length of sample. Sample is split in half down the middle so 25cm length of sample is then 1kg.


This is all based on a bit of googling so may be wrong but the math seems to check out. This means that if we only have one of these Au chips every 0.25m, grade across each 0.25m interval will be 1.24g/t. Then consider all the smaller grains of Au and the chips within the core that aren't visible.
