Environmental Impact Assessment and Management Plan
2016-5-21 Namibia has good reserves of the necessary raw materials. The proposed site has reserves of limestone, shale containing sufficient iron and aluminium, and silica all estimated to be sufficient for more than 100 years. Gypsum is also needed, which can be sourced elsewhere in Namibia or can be imported from outside Namibia.

Limestone extraction SOLANCIS
Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. This study investigates the existence and quantity of stone at the site and also the
