I doubt that this will get as much attention as recent failures in Brazil, but it proves that this is an issue that has has no national boundaries

And yet another mining dam failure......

From the link it states the dam failed after heavy rainfall and that this was used as a hydro electric dam.
I would assume that the dam overtopped or was at a higher than normal water elevation. This probably could have been avoided by lowering the reservoir level prior to the rain event.

And I wonder if any local deforestation contributed to it too.

there won't have been any way of controlling the level.
This will be a beaver dam across the river with absolutely zero civil engineering involved.
Its a river bed gold mine.
They will have done the dam with a mine suction hose/pipe under it which will have been fed into a pump converted to a generator.
I have seen a couple of these setups, there is water seeping everywhere. No escape route if it over fills apart from over the unprotected top. Its just a huge lump of local materials blocking a water flow with a pipe though it.
