I think you made a good purchase - I didn't realize it was trading below cash value. Of course, I don't know what the cash burn is - that would require reading financial statements - something I no longer do.
While there is no clear evidence of a bottom, there are hints - the last few days of heavy selling smack of capitulation. Also, a lot of the juniors are bottoming and starting to come to life, as the fear trade continues to dissipate. So I bought some today - I'll sell if it pops up or reaches my best before date (January 31).
