RE:RE:RE:RE:RE:RE:RE:Just an observationThese are good questions that can't be answered in terms of facts, but they can be answered in terms of risk:
Risk One: to survive, the company will have to raise cash at terms that are highly disadvantageous to current shareholders. This is affected by the side of the environmental cleanup bill, the amount of time production is out, and the cost of repairing the infrastructure. The first and third of these could be very expensive, and the second is unknown. It's not guaranteed that the company will survive, in a way that current investors can benefit from.
Risk Two: lawsuits and liability. Unknown, but potentially vast. If the company is shown to be negligent, they may lose their permitting.
Risk Three: loss of reputation. This isn't a physical risk, but one to shareholders; owning the stock, you have to put your faith in a management team that failed. This might not matter to you, but it does mantter to the financial people who will be lending them money.
Risk Four: physical risk. It's not yet certain exactly what will be required to make the mine functional again in a purely physical way. The current management failed to build a physically safe mine the first time around, now they have the unstable remnants of their first attempt to consider as well.
