"where some Australian Mining companies - already on the stock exchange" ... "to get listed on the stock exchange"?

I heard that it was the small dotcoms that were looking to get on the stock exchange would buy enough shares in the inexpensive mining companies and then as majority shareholders have the mining company buy out the dotcom (or at least merge with it)... or something like that.

I'm guessing it's the same thing that you heard, but the way you worded it confused me. Or my coffee hasn't kicked in. Either way.
