Ann: Letter to Shareholders, page-7

Idk what else to call it. What causes a mine collapse?
- Poor safety culture
- Dodgy workmanship / cutting corners
- A force majeure event

How is someone who isnt an insider supposed to do due diligence on any of these?

I'm just as disappointed as every other shareholder to lose my money in this way but the only lesson I learnt from this failure of an investment is to skim more profits next time when a stock is up.
Going deeper into the quarterly/annual reports and cash balance analysis isnt going to help me predict the next mine collapse.
At this point im in the final stage of grief lol, just accepting everything and waiting to claim my tax loss
