ENVIRONMENTAL OVERVIEW AND ENVIRONMENTAL MANAGEMENT PLAN FOR EXPLORATION ACTIVITIES ON EXCLUSIVE PROSPECTING LICENCE EPL4185 AT WLOTZKASBAKEN January 2013 Prepared by: Gecko Namibia (Pty) Ltd Gecko House 8 Sinclair Road Windhoek, Namibia Reviewed by: Nam Enviro Management and Training Services cc Mutjinde Katjiua SUMMARY Gecko Namibia (Pty) Ltd, in the name of its subsidiary Gecko Salt (Pty) Ltd holds EPL4185 which covers 75,335 hectares of coastal desert plains from north of Swakopmund to just south of the Henties Bay peri-urban area. Gecko intends to establish the “Vision Industrial Park” and harbour within the area. The development will require a large amount of fine and coarse aggregate material as well as armour stone for the construction of a breakwater facility. Besides the envisaged VIP development, Gecko is in the process of exploring a number of high-grade marble occurrences on this EPL. As part of the EPL4185 falls within the Dorob National Park, Gecko is submitting this EIA together with Environmental Questionnaires and other prescribed documentation in application for an Environmental Clearance Certificate under the Environmental Management Act of 2007. The company has drawn up an Environmental Management Plan for the prospecting operations and is currently in the process of implementing those measures. Management and exterior control on the adherence of the proposed mitigation actions are considered important tools in preventing negative environmental impacts from the operations. Activities during the exploration phase include sampling, testing and exploratory drilling. The activities are temporary and are conducted at a small scale than those at the drilling/development, production, and decommissioning/reclamation phases. The impacts described for each resource would occur from typical exploration activities, such as vehicular traffic exploration drilling and bulk sampling. Potential impacts from these activities are presented in this study. Gecko Namibia (Pty) Ltd EIA for EPL4185 January2013 1 TABLE OF CONTENTS 1.
