Forgot to add this open pit data for Opasura West.



Here is an example of the best section at Opasura East #5 with blocks and what data were entered to spreadsheet for tonnage and grade calculations.



For Dolcevita.
I said I would comment further on discontinuities after all the data for phase 1 came in.

Since then I have wondered if the difference between variability and discontinuity were part of the difference in opinion on the subject.

My interpretation and drafting may not be the best but trying to join the intersections to create a continuous mineralised zones is not easy and probably real rather than a drafting issue.

As would be expected from surface mapping there are probably local faults.  

AZS have been more sparing with faults than I have but use flexures/rolls to show more continuous zones - I don't think it works everywhere and some faults are almost certainly there.

Discontinuity vs Variability

Discontinuity - significant break 10+m which would make mine planning a bit of a challenge.  Definition?

For section 5 apparent discontinuities IMO occur with nearly every block.  Some blocks are obviously from stacked lenses and hence by definition separate though with available data which lens matches which is not possible to say.  The sections to the SE of 5 (6 & 7) are relatively continuous but with apparently variable grades and thickness.

Variability
Section 3 Opasura West is one of the more continuous ones.


Grades vary from 4% to 27%.
Widths 0-1m to 8m,
The 7 blocks on the section reflect this.

This variability is present on most sections to a greater or lesser degree.

I didn't try to locate the original posts about this so not certain what the issue was other than a vague memory that an earlier response would have been better.
