Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce commencement of a preliminary economic assessment (“PEA”) for the Iska Iska silver-tin polymetallic project in the Potosi Department of southwestern Bolivia. The PEA study will consider the inferred mineral resource estimate (“MRE”) of 560 million tonnes grading 13.8 g Ag/t, 0.73% Zn and 0.28% Pb in the Polymetallic (Ag-Zn-Pb) Domain and 110 million tonnes grading 0.12% Sn, 14.2 g Ag/t and 0.14% Pb in the Tin Domain (Sn-Ag-Pb). While the Polymetallic Domain and the Tin Domain do not overlap or share any resource blocks, for the purposes of the PEA the mineral resources within both domains will be combined. read more

Eloro Resources Announces Robust Initial Inferred Mineral Resource Estimate of 670 million tonnes containing 1.15 Billion In-situ Ounces Silver Equivalent for Iska Iska Project, Potosi Department, Southwestern Bolivia

Total in situ metal estimated to be 298 million ounces Ag, 4.09 million tonnes Zn, 1.74 million tonnes Pb and 130,000 tonnes Sn totalling 1.15 billion ounces silver equivalent. Due to the multi-metal nature of the deposit, the resources are reported using Net Smelter Return (NSR) cut-off values which are as follows: Polymetallic (Zn-Pb-Ag) domain = US$9.20/t for open pit (OP) and US$34.00/t for underground (UG) mining; Tin (Sn-Ag-Pb) domain = US$6.00/t for OP mining. Costs have been significantly reduced due to the major impact of the positive “ore-sorting” tests. Potentially open pittable inferred mineral resource in Polymetallic Domain (Zn-Pb-Ag) of 541 million tonnes at 0.69% Zn, 0.28% Pb and 13.6 g Ag/t for an NSR value of US$20.32/t at a cutoff of US$9.20/t. Includes higher grade near surface inferred mineral resource of 132 million tonnes at 1.11% Zn, 0.50% Pb and 24.3 g Ag/t for an NSR value of US$34.50 at an NSR cutoff of US$25/t. Potentially open pittable inferred mineral resource in the Tin Domain of 110 million tonnes at 0.12% Sn, 0.14% Pb and 14.2 g Ag/t for an NSR value of US$12.22/t at an NSR cutoff of US$6.00 per tonne. Potential underground inferred mineral resource in the Polymetallic Domain of 19 million tonnes at 1.88% Zn, 0.36% Pb and 18.8 g Ag/t with an NSR value of US$42.23 at a cutoff grade of US$34.40. Total inferred mineral resource, 97% of which is potentially open pittable, is 670 million tonnes at an NSR of $19.62. Potential open pit is 1.4km in diameter, extends to a maximum depth of 750m below the Santa Barbara hill and has a stripping ratio of 1:1. Resource estimate is based on 139 diamond drill holes totalling 96,386m. All holes intersected significant reportable mineralization and the deposit is open in all directions.

Eloro Resources intersects Significant Tin Mineralization (0.17% Sn over 52.75m) in Mina Casiterita Property and also Receives Strong Results from Infill Holes at Santa Barbara Deposit, Potosi Department, Bolivia

Tin mineralization at Casiterita is located 2km southwest of the Santa Barbara deposit indicating that the overall Iska Iska mineralizing system is much more extensive, as predicted from geophysical data. Further drilling is required to fully evaluate this prospective target area.

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).

Cartier Silver Outlines an 800m by 500m Epithermal Silver Polymetallic Target on Gonalbert Property, Potosi Department, Southern Bolivia

Gonalbert is underlain by a dacitic intrusive dome approximately 1,300m by 600m which hosts epithermal Ag-Pb-Zn mineralization along structures that are exposed in a number of historical and recent artisanal workings and trenches. An IP chargeability anomaly surrounding the structures covers an area of 800m by 500m and extends to a depth of at least 400m, the depth limit of the survey. The chargeability anomaly becomes stronger, especially at depths greater than 100m, below a depleted, near-surface zone where sulphide mineralization has been extensively oxidized. Drilling to test this anomaly will commence shortly.

Eloro Resources Outlines an Extensive IP Conductivity Anomaly on the Casiterita property adjacent to the Iska Iska Silver-Tin Polymetallic Project, Southern Bolivia

Magnetic data strongly suggest that a large intrusive body lies below the Iska Iska Caldera Complex and that it is nearer to surface on the Casiterita property. This intrusive is approximately 5km long by 3 km wide. Diamond drilling and geophysical surveys are in progress to test for a potential major tin porphyry south of Iska Iska and on the adjacent Casiterita property.
