TK has invested in plenty of stocks that have gone seriously south EUC & MEI certainly spring to mind but you should do more than cursory views of SP in those companies - as posters in this thread have rightly said BGL were well on the way to proving up an economic gold resource before TK came on board and NCZ was a mothballed plant with resources that simply required a better economic outlook on zinc and some cash to restart operations!
As you have invested in A1G you should really ensure you understand everything in the prospectus or ask someone you trust to inform you!
