EL 22244 and EL 22245 Karawa (Foelsche) Project Final technical report for the period 3 March 2003 to 6 March 2011

Abstract

This final report describes the exploration activities conducted on the EL 22244 and EL 22245 from their grant on 7 March 2003 to their expiry on 6 March 2011. The EL 22244 and EL 22245 were granted to the Astro Diamond Mines Limited (Astro). Astro placed them in its Calvert Hill Project and carried out initial phase of exploration in three stages. During the first stage, Astro acquired all relevant geological information comprising historical exploration data and publicly available government geophysical and geochemical data. During the second stage, information received was meticulously evaluated to generate targets and structuring of exploration program. During the third stage, identified targets were geophysically mapped by airborne EM and ground gravity surveys. The aim of exploration was to explore for commercial source of diamonds. In 2006, Legend International Holdings Inc. (Legend) was appointed to manage Calvert Hills Project. In the following year (2007), Legend became their owner and operator and continued with the planned exploration work until the surrender on 6 March 2011. During Legend's ownership, tenements remained part of the Calvert Hills Project for 2006-2010 duration but subsequently in 2010-2011, the project was renamed as 'Karawa Project'. Legend conducted HMA sampling, rock chip and soil geochemical analysis programs and drilling targeting kimberlites. During exploration three consultants, a geophysicist, a photogeologist and a mineralogist, were engaged to provide professional input to the company's acquired exploration data.
