The mineralization found in tailings at the CMP has been deposited by manmade processes following grinding and flotation processes of black pyritic shale and is therefore not characteristic of a traditional manganese deposits. The material can be physically characterized as a compacted soil, with varying degrees of particle sizes from clay to coarse sand.

There is sorting of the flotation waste by grain size and weight, resulting from the sedimentation from the edge to the center of the tailings deposit (based on other tailing pond borehole sludge studies (Novotny et al. 1972). Subsequently, three zones of grain sizes in the tailing pond can result with:

- An outer zone of fine-grained sand and silty sand

- A central zone of alternating sandy laminae with the outer and inner zone types, and

- An inner zone comprised of silt to slightly clayey silt (finest material of all zones).

This zoning is typical for slurry tailings and results from sedimentation of deposited slurries; from fluctuation of water levels during decantation operations (removal of water) within the central zone, and a gentle slope (1.5%) leaving little to no water in the outer zone (Bateria Slany, Chapter 2 1989).

The Chvaletice bedrock deposits of iron and manganese mineralization constitutes one horizon in the metasedimentary stratigraphy with variable proportions of carbonate and silicate minerals occurring laterally from west to east ........

Milos et al. (2018) conducted a comparative evaluation of various tailings extraction and transportation methods. The methods evaluated include excavators and trucks, hydromonitoring, conveyors, and pipelines for transport. The following points have been extracted from Milos et al. (2018) on the benefits of the use of excavators and dump trucks for tailings extraction:

- Transport by dump trucks provides flexibility and enables operational increase in or decrease of the mined tonnage.

- Breakdown is easily solved by using back-up capacity of dump trucks or by sub-contractor, at extraction operation or at rehabilitation.

- Dump trucks are used for both, tailings extraction and rehabilitation.

- Tailings extraction is very flexible as an excavator along with the dump truck fleet can be moved operatively according to head grade requirements.

- Dry ore and dry tailings stockpiles require smaller areas and capacity may be temporarily increased by stockpiling ore at the mine site.

- More economic water management, water remains in the processing plant, contamination of the tailings extraction operation and the rehabilitation area is limited.

The use of excavators and dump trucks to extract and transport the tailings to the mill is the selected method.

Tailings extraction using excavators and trucks will take place in 5 m high benches, with berms a minimum of 20 m wide, and bench faces angled b ........
