Ann: Oposura Drilling Update, page-11

PS I am quite tired and started doing stream of consciousness style musings which are meandering.  Some effort put into this post so putting it up but consider it only a draft which will need significant editing. GLTAH

First pass crunching of the numbers is summarised in this diagram.

What does it mean? 

No easy answers as there are many complexities which will need to be fed into a very detailed study. 

AZS give this sectional view to which I have added some information.

Showing only the good intersections?.

The main mineralised zone is consistent around the 1180m RL but shows moderate to strong local variation.  This section IMO is selected very carefully to give perhaps one of the best impressions of the Opasura East deposit's western edge.  This is the most obvious high grade thick zone of mineralisation and will provide the incentive to go underground in a way that may well provide a good return. 

The devil is in the detail which is the nature of mineral deposits being variably complex beasts when formed and further complicated by subsequent structures which can impact of what is economic.  The really big orebodies (e.g. Olympic Dam) have long and complex histories with multiple phases of mineralisation and structure which is, in part, what makes them so valuable.  Opasura is certainly not in that class but is IMO good enough to warrant significant further studies to see if it can make money for AZS.

Some comments about the methodology for today's M% diagram - The boring, variably important stuff.....

• Transfer of AZS's assay and location data into an excel spreadsheet.  I now have ?all of this for Opasura up to this week's announcement.  Would be great to have good computer programmes to handle it automatically.  I don't so there will be errors, omissions given the sheer volume of work involved.  I enjoy it.  DYOR and check if necessary.

• Metre % numbers contain length and grade (Zn+Pb in this instance) and are a simple multiplication of them to give a number that is potentially useful for graphic and predictive purposes.
• NOTE  a high number can be from a narrow high grade zone that could be below the mine parameters but the grade can carry the dilution.
• Or the same high number could be a very thick intersection of high grade that could only be mined in a bulk open pit situation.
• The M% numbers used are from intersection lengths and grades down hole.  The mineralisation is essentially horizontal so vertical holes will give something close to true thickness.  However, some holes have been drilled at less than 60 degree dip (Holes 184 and 185 at nominal -45 degrees (174 -20!)) which means M% numbers can be skewed by length.
• I have focused on high and low M% and left out some of the stacked zones that are intermediate but could make some money if they need to be mined rather than waste.
• Next steps for this would be to look at how the intersections sit in 3D spaced
• For this map IMO the majority of Red stars and Orange hexagons will fall within potential economic parameters for individual intersections.  The real issue is can AZS tie them together into a mine plan.
