fragmentation of gold mining industry | Postjudice
With the exception of Kinross’s advances in West Africa (and the earlier Newcrest-Lihir tie-up), the gold mining industry has been remarkably quiet on this front. This relative inertia continues despite the much higher level of fragmentation than in the case of more M&A-prone potash or iron ore industry.
