Compared to other mining methods, room-and-pillar mining is a low-cost method with a low recovery rate (since some ore is left behind in pillars). Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being on top and ore being at the bottom. Direct operating costs for room-and-pillar ...

This rudimentary mining method has continued to date among ASGMs. Geologists posit that gold exploration in the country has been mainly directed towards the rediscovery of quartz veins at old work sites, at the expense of lands. This has led to inaccurate conclusions that Zimbabwe has been over prospected.
The mining method used at the Mimosa platinum mine is the bord-and-pillar mining method, with an average stoping width of 2m. The ore body at Mimosa mine is superficial and is accessed through the Wedza and Mtshingwe shafts. The Wedza subchamber hosts the economic main sulphide zone, which comprises the economic PGM and base metals.
Summary: Unki platinum mine is in the southern half of Zimbabwe's Great Dyke geological formation–widely ecognised as the second-largest resource of PGMs in the world. The Great Dyke in Zimbabwe occurs as a 2.5 billion-year-old mafic to predominantly ultramafic layered intrusion, over 500km long, trending in a north/north-easterly direction.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
The estimated costs of equipment for the proposed surface mining, underground mining and processing methods are $ 996 222.00, $ 392 912.00 and $ 40 707.00 respectively.
