Bulk Tonnage Metallurgical Tests Return Significantly Higher Silver Head Grade of 91 g Ag/t Compared with the 31 g Ag/t Average Grade from the Original Twinned Holes in the Polymetallic Domain at Iska Iska, Potosi Department, Southwestern Bolivia
Metallurgical tests from a 6.3 tonne PQ drill core bulk sample representative of the higher grade Polymetallic (Ag-Zn-Pb) Domain returned a significantly higher average silver value of 91 g Ag/t compared to the weighted average grade of the original twinned holes at 31 g Ag/t strongly suggesting that the average silver grade is likely significantly underreported in the original twinned holes due to the much smaller sample size The metallurgical tests confirm the viability of “Ore-Sorting” and Dense Media Separation at Iska Iska Project. Excellent pre-concentration results from the higher grade Polymetallic (Ag-Zn-Pb) Domain are now proven in a bulk sample. The 91.9% recovery of silver and lead with 76.0% recovery of zinc into a high grade (176g/t Ag, 1.88%Pb, 2.86%Zn = 299.15 g Ag eq/t) potential mill feed stream that contains only 46.6% of the Run of Mine Tonnage. The introduction of the pre-concentration stage allows Eloro to have more operational flexibility based upon conducting economic trade off scenarios between reducing downstream capital-operating costs and optimizing overall metal recoveries. XRT Ore Sorting is proposed for the coarser size fractions and Dense Media Separation (“DMS”) for treatment of the finer fractions so as to pull on the strengths of both technologies. The size split between the two technologies is unoptimized and the current results support the ability to potentially “ore sort” slightly coarser rocks than tested which would further increase the overall benefits of pre-concentration. Tin (Sn), although not included in the 132 million tonnes higher-grade starter pit area (MRE), is expected to potentially contribute to the enhanced values in the initial Preliminary Economic Assessment (“PEA”) with additional metallurgical testing and infill drilling.
