At the end of all of our interviews, Steve and I always ask our guests two questions: what is something they think that needs to live and what is something that needs to die in the mining industry? We thought it would be interesting to put together some of these responses we have received to those questions over the years. So on this episode of Ideas That Must Die in Mining, we are joined by, in order: Jon Goodman, Attila Pentek, Jon Hronsky, Tony Manini, Hedley Widdup and Mary Poulton. Lets find out what they had to say.
