Pretty easy to read.
It is amazing that you dismiss terrible drill results.
For a mine with very little reserve left, these drill results are pretty fundamental.
They are already chewing through the low-grade stockpile. They wouldn't be doing that is they didn't have to.
The tailings dam is irrelevant. They don't have a choice but to upgrade it, and are upgrading in stages.
Fact remains, although we are all confident the mine life will be extended, they are drilling (so far unsuccessfully) to achieve this aim.
I don't know why this is an argument. The market clearly agrees that this is a real risk, and overwhelmingly positive drill results will lead to large increases to the share price.
