Origin of Material
This standard was made using ore sourced from the AngloGold Ashanti (Namibia) Ltd – Navachab Gold Mine. This mine is located in Namibia, 10km southwest of Karibib and 170km west northwest of Windhoek. The orebody is located in the Central Zone of the Pan-African Damara Orogen. Gold mineralization is hosted by a steeply dipping metamorphosed sequence of interbedded siliciclastic and carbonate rocks. All lithological units contain mineralization to some extent within sheeted quartz veins. The calc-silicate/marble unit (MC) hosts higher-grade replacement skarnoid mineralization. Carbonate rich ore for this material was blended from selected RC borehole chips.
