Ann: Boseto Operations Update July 2013 , page-2

it would seem:
~ mining tonnes constant;
~ blasted stocks available significantly increased. Expect more about access rather than activity;
~ processed tonnes relative constant
~ processed material higher metal contents
~ lower Cu recoveries (80.0% vs 87.4%); Ag constant @ 84%

Overall then, relative to June better feedstock but lower recoveries delivering about the same metal content.

Not stunning but at least stable.

Lower metal recovery bothersome in as much constant processing rate not maintaining yields. Represents IMO about 170 t / month ... in a year that's a nice slice of revenue (... aka bottom line...);

No insight into costs but if accept volumes driven, C1 costs will still be uncomfortably high;

Saving grace might be [forward looking] Cu price holding up...

Cheers
