Complete represented report chrome 1 Report on

2013-6-20  6.2 The current chrome mining activities are primarily artisanal and restricted to mainly open cast mining which is an environmental hazard. However such type of mining approach will only access the chrome seams to maximum shallow depths of about 20m and the site is abandoned, yet these same chrome seams persist to greater depths below the mined pits, that need conventional underground mining. The thrust is to encourage more of conventional mining that will include mine planning for underground operations and thereby exploit the chrome seams to much deeper depths and hence more production for the country. This is the reason why you will notice that when Zimasco and Zimalloys were in full production before independence, most other operations where underground mines and this phenomenon of shallow pits all over the dyke is a result of artisanal mining
