So here is the gold mining industry's AIC - (total costs i.e AISC growth capex, G&A, M&A, dividends etc.) vs the gold price. As you can see its been a horrible business, slipping in and out of marginally positive and negative free cash flow over the past 15 years. And suddenly...Boom! Massive positive margin expansion. I'm not sure anyone is really getting this outside the sector specialists. In theory the industry can now, for the first time in living memory, finance reserve replacement and a much higher return of capital to shareholders from FCF.
