Agree snc mining companies have a typical trading pattern to them. They go high when the excitement builds after discovery and during permit stage. Then fall when the reality of funding hits. Once this is finalized they build again as production gets close or starts. Is the fall unusual? I would say no. Is the degree of fall unusual? Possibly but don't forget this is a very large and valuable asset and it requires sizable capital. So extreme price movements may be expected. Smaller companies have been through this as well. Look at image and strandline or BSE.

am I panicking? Not at these prices. I just wish I could buy more but timing stops me.

still everyone needs to do their own research and decide is the rollercoaster ride what they want or not, as its possibly going to be here for a while yet.
