Havilah Resources Limited provides an update on progress of work at its large-scale Kalkaroo copper-gold-cobalt deposit (Kalkaroo) in northeastern South Australia, near Broken Hill. Havilah's priority focus during recent months has been on advancing several key tasks that are required to commence the West Kalkaroo open pit gold mine. Several infill reverse circulation (RC) drillholes were completed along strike of the proposed West Kalkaroo open pit to improve confidence in the continuity of mineralisation. These results will be used in future mine planning studies. Widespread copper and gold mineralisation was intersected in most drillholes, with grades and widths of mineralisation very typical of the Kalkaroo deposit, including: KKRC606: 17 metres of 2.24 g/t gold from 110-127 metres (native copper zone); 46 metres of 0.49% copper from 110-156 metres (native copper zone and chalcocite zone). Extensive faulting and fracturing is likely enhancing the grade of gold mineralisation in this area. Low-grade base of Tertiary gold mineralisation was also extended by shallow aircore drilling within or adjacent to the proposed West Kalkaroo open pit. Six sterilisation holes have been completed in the vicinity of the planned locations of key infrastructure, including the processing plant, tailings storage facility and waste dump, to ensure that they will not be built too close to potentially economic mineralisation. The PEPR document, which is the final permitting approval required for commencement of mining, was submitted to the DEM during March 2021. Thusfar, Havilah has had no feedback other than in relation to the calculation methodology of the rehabilitation bond, which it is in the process of addressing. Havilah has conducted Kalkaroo site visits with potential mining contractors with a view to agreeing the terms and scope of possible mining contracting arrangements. The process flow sheet design is well advanced, with further refinement in equipment selection. The process plant has been designed to treat the soft oxidised and clayey ore material and would recover coarser gold and native copper (greater than 50 microns grain size) by gravity methods. The finer gold would be recovered via a conventional cyanide leach circuit. A positive feature of the Kalkaroo deposit is that while there is a high proportion of sub-10 micron saprolite gold ore material, there is very little gold in this size fraction. This raises the possibility of rejection of a large mass of the very fine clayey material prior to leaching, thus effectively increasing the leaching circuit ore throughput.
