It is taking longer than I expected to get the CIL results, they must be getting close. We have had a few punts on what the grade from the "heads" fresh material will be, I am sticking with 15 g/t, that would be a great result for the diluted material coming up from the mine IMO. The tails are a very different story. The results from 31/01/18 ranged from 4.75 up to 11.9 g/t, they where from test pits so not the same sampling method for the CIL testing, that was taken with a trench sample. They reported an average grade of 9.27 g/t, that is the grade we have been working on, but not likely to be the average over the 40k tons. Going from memory, when the wheels fell of, MP told me they expected the diluted head grade to be around the 8 g/t, and ended up recovering around 2 g/t, leaving 6 g/t behind. There was all sorts of number being thrown around at the time, 70 to 80 percent recovery, recovering 2 g/t, working backwards would have been a feed grade of around 3 g/t putting 1 g/t in the tails. There will be hot spots and cold spots over the tails dumps for sure, the trench will give us a better idea of what to expect but still could well over or under the end result. So if I take the what I consider to be the worst case, 1 g/t and the best case, 9 g/t the average would be 5 g/t, a perfectly respectable grade, better then most operating mines. That would give us 6 or 7 thousand oz sitting in the tails, could much more, could be much less for sure. When we get the results from the CIL on the tails it will tell us much more than the grade alone, and we need to temper our expectations, be them good or bad expectations, with the fact it is still only a small area of the tails and could be in no way representative of what the tails hold. However, as it was taken from a trench, so it would be more representative than any results we have to date, so still an important number,,, I hope it's not a doughnut....

Thanks once again Jimone.

If your estimates are right (15 g/t & 5 g/t), what would that mean for operations, or rather changes in operations? I assume we would even more urgently need a ball mill, flotation circuit...and of course that very elusive CIL plant (not holding any hopes for CIL, given that this is Brazil!). Would we utilize some existing equipment on the site, more intensively, based on your estimates turning out to be right?

And if your estimates do come to be true, what does it mean for the share price of OGX?

All the above is of course nothing but scenario analysis. It may also help if you examined the other extreme scenarios for tailings (1 g and 9 g) and what they would mean for changing operations.
