Ann: Investor Presentation Video, page-26

Interesting to see an initial mining plan for E and W Opasura included in the video.  
These are obviously "pretty" cartoons for presentation purposes and represent only the tip of the iceberg for the amount of work that has been done to date on planning.  
The 3D aspect of the image below gives an idea of where the relatively flat lying Arenillas Formation could come close to the surface north of both Op E&W and the central zone.




What do the colours represent? Some ideas:
Magenta - ?open pit "ore" blocks?
dark red. ? UG "ore"
Light yellow and Light pink - ?Arenillas formation and ?sulphide zones respectively.

At Opasura East it looks like most of the 'central' zone (near historical development/adits) is shaping up as an open pit.  These are among the highest grade portions of the deposit and could augur well for quick cash flow.

I am a bit puzzled by what TR meant about only 25% of the exploration target being tested.  
The original areas were given in September and again in recent presentations with phase 1 drilling completed shown which IMO cover at least 50+% of the circled areas drilled on a first pass basis:




Whatever there is significant upside potential at Opasura which Phase 2 drilling will begin to explore.
