Dams rarely give way "suddenly", they erode. Either undercutting, over topping or side erosion, water under increasing pressure will eat away and
eventually the damn will fail. Sounds like they were concerned about that and sent the drill team to determine where water was saturating or traveling
through the dam.
The initial structure of the dam was designed to hold back so much slurry. Ongoing operations would surpass this limit at some point. They know what
the limits are and the overburden they were applying. Unlike dams with sluice gates there is no built in relief for water backing up or sudden
additional pressure, like heavy rains, for instance.
The dam is designed solid, so failure at some point is inevitable. Problem for the company is solved. In the long ruin, there will be an
"investigation", a "token cleanup" and fines levied (a drop in the corporate bucket of waste).
Business as usual.
