| ABSTRACT: | Kamoa North exploration success highlights the potential for significant resource expansion at Kamoa-Kakula and on the adjacent Western Foreland exploration licences that are 100%-owned by Ivanhoe Mines The newly delineated copper corridors at Kamoa North occur on the western flank of the un-mineralized Kamoa Dome. The most significant corridor trends north and south for more than nine kilometres before swinging to the northwest and is projected to continue onto the adjacent Western Foreland exploration licences that are 100%-owned by Ivanhoe Mines. The second corridor trends west-southwest, away from the Kamoa Dome and toward the West Scarp Fault, over a distance of three to four kilometres. The copper corridors are indicated with dashed and dotted lines in figures 3 and 4 (pages 6 and 7). The corridors are partly within the previously defined Inferred Mineral Resources, but the definition provided by additional drilling has allowed significantly increased continuity of grade to be established and then extended along strike into previously untested areas. The recognition of high-grade trends in areas previously tested by wider-spaced drilling reflects a growing understanding of the controls on mineralization at Kamoa-Kakula. Mineralization thicknesses range from three metres up to 30 metres at a 1% copper cutoff. The mineralized horizon generally is in the region of 150 metres to 300 metres below surface, except on the west side of the West Scarp Fault, where it strikes roughly north– south and dips gently to the west at between five and 10 degrees. Copper sulphide mineralization at Kamoa North tends to be bottom-loaded and shows typical downward zonation from chalcopyrite to bornite to chalcocite. Chalcopyrite dominates in the lower-grade intercepts and when mineralization extends into the overlying pyritic siltstone. Fine-grained bornite and chalcocite dominate in the highestgrade intersections. The Kamoa North discovery area already is accessible by an all-season road that connects with the provincial road to Kolwezi and is close to the newly installed electricity line running from Kamoa North to the planned Kansoko and Kakula mines. | |
