Frequently Asked Questions
What is an ore?
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically a mineral of value that can be extracted profitably from a resource deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.
What is Manganese Ore?
Manganese ore is a silver-gray with a blueish tinge. It is a hard metallic element, although it is quite brittle. Manganese ores are found in metamorphic rocks or sedimentary deposits. Pyrolusite is the main ore mineral for manganese. Manganese combines easily with air and water and is therefore a reactive element frequently found in nodules on the sea floor. It is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels and is important in steel production.

Where does manganese occur in the natural environment?
Manganese (Mn) is a naturally occurring trace metal commonly found in the environment. It is the twelfth most abundant element in the earth’s crust, present in rocks, soil, water and food. It does not occur naturally in a pure state and the most important Mn-containing minerals are oxides, carbonates and silicates.

What is copper ore?
Any rock containing commercial amounts of copper. Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color.

What is Iron ore?
These are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4 , 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)•n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).

What is Gold?
It is a chemical element with symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

What is your approach to dealing with the environmental impact of mining?
We recognize that mining can have adverse ecological effects, and are committed to minimizing the environmental impact of our activities. We work towards preserving the natural environment around our mines, by taking all possible measures to mitigate adverse affects. This approach is reflected in our Environmental Impact Assessment (EIA) for our licensed mining area, which has been integral to our planning for the Mbabarenyi mine site in Taita Taveta County.
