I certainly think the question is worthy of asking. I personally overlooked it as possibly being the same issue that Twangiza faced, as when I read the Q2 Mining Results I interpreted the reason for the minimal stacking to be due to other issues, rather than a stockpile that was too wet.
Below is the excerpt from the PR that addressed the decrease in stacking levels at Namoya in April. The section in bold led me to believe that this wouldn't have been an issue had all their materials and supplies been on hand, but I could be totally off-base.
The significant decrease in stacking levels from March's 103,163 tonnes to April was also driven by the adverse impact of unseasonably high rains which interrupted supply routes and the ability to deliver procured materials and supplies. The availability of ore from mining activities and the available medium grade stockpile material resulted in the stacking of ore with an average grade of 1.52 g/t Au.
One thing I know for sure in the years to come, I'm going to watch out for April. Q1 is historically the wet season, but April these last 2 years has really thrown a wrench into their production. At least this year it only caused a minor delay. Last year, on the other hand, was a kick in the beans.
