We offer real and permanent good to everyday people




We intend to finance, acquire, or partner with small scale mining companies throughout Africa. There are a number of issues concerning the working conditions of small-scale informal gold and diamond diggers throughout Africa. Among these are the unhealthy, unregulated and sometimes dangerous environments in which diggers work. In addition, the majority of diggers do not know the true value of rough diamonds making them vulnerable to exploitation. Reef Mining Company is keen to help find solutions that generate wealth, build infrastructure and help redevelop countries that are home to small-scale informal alluvial diamond digging. We are currently working with three initiatives in order to achieve this objective.

                                    ALLUVIAL DIAMOND MINING FACT SHEET

     Alluvial diamonds is the term used to describe diamonds that have been removed from the
   primary source (Kimberlite) by natural erosive action over millions of years, and eventually
   deposited in a new environment such as a river bed, an ocean floor or a shoreline.

What is alluvial diamond mining?

    Alluvial diamond mining is the term used to describe the process through which diamonds
   are recovered from such deposits of sand, gravel and clay. Large concentrations of alluvial   
   diamond deposits are mined on an industrial basis. However,most alluvial diamond deposits
   are spread across huge geographic areas which cannot be easily isolated and therefore are
   not mined industrially. These deposits are mined informally, in a non regulated way. This is   
   commonly known as artisanal or small scale-alluvial diamond digging. Around 10% of the
   world’s rough diamonds are sourced through industrial alluvial mining and14% through 
  artisanal or small-scale informal alluvial diamond digging.

Where are alluvial diamond deposits found?

Alluvial diamond deposits are found on the Atlantic coast of South Africa and Namibia, as well as in some riverbeds in Angola, Sierra Leone, Democratic Republic of Congo, Central African Republic, Cote d’Ivoire, Guinea, Ghana, Liberia, Tanzania, Togo, Brazil, Venezuela, Guyana, and South Africa.

How are alluvial diamonds mined?
 Formal/industrial alluvial diamond mining. Formal (also known as industrial) alluvial diamond mining is characterized by high investment,strict regulations, government investment and is conducted by formal mining companies.Formal alluvial mining requires a considerable amount of material (called the ‘over-burden’) to be removed first to get to the gravel bed underneath, where diamonds are found. When diamonds are found on the ocean shore or on riverbeds, the gravel is removed and then taken to a plant where it is washed and screened for diamonds. For diamonds that are found offshore, i.e. on the ocean bed, specially constructed ships suck the gravel from the ocean floor before it is transported to land and on to the plants for screening. All the gravel and sand that is removed is specially treated and  then reused in many different ways, such as replacing it to help rehabilitation in the area. Formal alluvial diamond mining mainly takes place in Angola, Namibia and South Africa.
Small-scale informal alluvial diamond digging

 Small-scale informal alluvial diamond digging (also known as artisanal diamond digging) is usually undertaken by individuals, families or groups using very basic equipment, such as sieves and pans, to search for the diamonds. This type of digging is very labor intensive as it entails first removing the sand on river banks and then extracting and washing the gravel in order to find diamonds. The majority of small-scale alluvial diamond digging is defined as Prevalence of small-scale alluvial diamond digging is highest in Angola and the Democratic Republic of Congo (DRC) but also takes place, on a smaller scale, in the Central African Republic, Cote d’Ivoire, Guinea, Ghana, Liberia, Sierra Leone, Tanzania and Togo. It is estimated that 1.3 million people in Africa work in this sector.

Diver-less Dredges

Small dredges with 4, 6 and 8-inch gravel pumps use divers. The work of diver is very dangerous. Collapsing underwater pit will cover up diver, which, in most of the cases, dies suffocated. Also, the diver can't control the flex hose above the 8-inch size. Larger dredges with 10, 12 or 14-inch gravel pumps have to use diver-less system.

The diver-less system has three major advantages:

  1. higher volumes pumped; better cost-to-income ratio;
  2. safer in use;
  3. ability to work inland of the alluvial flat.

Positive Recovery Results from Python at Kloof

Positive Recovery Results from Python at Kloof

The figures in Table 1 above indicate a gold recovery of 89.4% of the gold entering the Python section of the plant, in 26.4% mass. Pending the finalisation of the current modifications and optimisation of fine crushing in the VSI crusher circuit, the concentrate produced from the IPJs is pumped directly to the leaching section of the Kloof No. 1 Plant for final gold recovery.
