Big crashes tend to send the tide out on all stocks and cause a flight to safety (like gold and the US dollar). It would depend on what caused the crash as to which asset class is viewed by investors as the best place to run so it's hard to make any predictions for the future.

I've been holding TBR for a very long time so would not let another crash change that holding in any way. More likely I would only sell a few TBR when the price is rising not falling. That is my personal position so it may not suit others who have entered the stock later or have different investing trading philosophies. NST looks like it's shaping into a pretty solid company with great margins, good profits, no debt, an increasing production profile and a reasonably long LOM, so a good long term hold if $A stays strong like I think it should. I'd probably consider accumulating NST on any big retraces. As for RND I've only ever held a few but don't see much difference between RND and TBR other than TBR also having the assets in Ghana.
