“ In the Republic of Guinea we are working on a hybrid project that combines smart mining practices and the regeneration of the environment! ”

PMA Sarl has identified efficient and cost-effective water management methods in order to rehabilitate the river basin and maintain a balanced allocation of water for its specific uses (farming, fishing, mobility etc). This identified process will assure that water needed throughout the year is available and no longer prone to natural variations that have been considerably affected by global warming and irresponsible practices such as, deforestation for cattle and mining.

The method identified by PMA Sarl is called soil transposition via the use of dredging techniques. The project will be carried out throughout the allocated concessions, which represent 550km of the River Niger (Guinea) and 350km of coastal shore north of Conakry.

The main purpose of the project will involve the removal of accumulated and unwanted sediment from the bottom of and the banks of the river and coastal areas. Such sediment has negative repercussions as the riverbed becomes shallower, affecting its commercial applications (maritime traffic, fishing, farming), thus halting supply chains for basic resources as well as socio-economic activities that evolve the overall wealth of a country. Additionally, the unwanted sediment increases the water salinity and erodes the banks, presenting an environmental hazard for both wildlife and people, such as flash floods.

The advantages of the application of soil transposition are:

Widening/ Deepening for shipping industry Shore Replenishment – Reversing the effects of soils erosion caused by natural disaster or offshore mining Shore Replenishment – Reversing the effects of soils erosion caused by natural disaster or offshore mining
Excavation necessary for infrastructure projects like bridges, docks and tunnels. Waste Removal – Trash and plastics
Land Recovery/Construction Materials – Soil can be displaced and used for land-building projects Environmental Remediation - Cleansing of Lakes, Ponds or Lagoons where water is stagnant
Mining for Heavy Minerals and Precious Metals Remediation of Eutrophication – In Mali’s case, The Water Hyacinth that chokes water flow and fish stocks.

The project is split between the Guinean government (15%) and PMA and its partners (85%), Olimining Global included, and will conglomerate 33 soil transposition projects across the river Niger and on the coast of Guinea in the Atlantic Ocean. PMA estimates the project cost to be approximately USD 350m of which 60% of this will be financed by future profit made from PMA and its partners in mining, thus presenting a sustainable and cost-effective SPV that enriches the government of Guinee and provides over 6000 direct jobs for the youth of the country, as well as to rejuvenate the quality and flow of water and affected areas.

The rehabilitation of the banks of the River Niger, along with the securitisation of the Niger Basin against flooding will lead to the creation of eco-friendly artisanal, agricultural and industrial activities offering a wide range of employment opportunities for local populations, especially for Women and the youth. This project is one of the few being carried out where the conglomeration of social, ecological and economic matters is equally considered.
