Eloro Resources Reports Major Advances in Metallurgy for the Iska Iska Silver-Tin Polymetallic Project, Potosi Department, Bolivia
Preliminary tests at TOMRA in Germany indicate the mineralization at Iska Iska is amenable to “ore-sorting” with removal of at least 40% of the waste in the Polymetallic Domain and up to 80% in the Tin Domain which would substantially increase concentrator feed grades as well as reduce future operating costs and significantly lower the cut off grades (COG) for the pending mineral resource estimate (MRE). Positive “ore-sorting” results were obtained from composite samples of both the tin (Sn) and polymetallic (Ag-Zn-Pb) mineralization domains in the Santa Barbara deposit indicating its wide applicability throughout the entire deposit. Further metallurgical studies conducted by Wardell Armstrong International on a composite sample of the tin mineralization has improved tin concentrator recovery to 50%. This recovery is un-optimised and has been achieved using a mixture of Multi Gravity and tin flotation techniques which are specifically designed to recover the finer grained cassiterite. The concentrator could produce an approximately 5%Sn concentrate grade amenable to the tin fuming process that ultimately could produce a 60-70%Sn concentrate for smelting. The level of metallurgical and pyrometallurgical work that has been conducted is exceptionally high for an inaugural MRE but is justifiable due to the significance of this large potentially open pittable tin and polymetallic resource. The additional metallurgical/mineralogical knowledge will enable Eloro to rapidly move towards a preliminary economic assessment (PEA).
Eloro Resources Ltd. (;TSX: ELO OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce major advances on metallurgy for the Iska Iska silver-tin polymetallic project in the Potosi Department of southern Bolivia. These tests were directed by Mike Hallewell, C.Eng., Eloro’s Senior Strategic Metallurgist and a qualified person (QP) as defined by National Instrument 43-101 (NI 43-101). in consultation with Micon International Limited Principal Metallurgist, Richard Gowans, P.Eng., an independent QP.
