CHANNEL SAMPLING AT PORCO ADIT RETURNS 103M STRIKE LENGTH GRADING 521 AG EQ/T (INCLUDING 117 G AG/T, 1.44 G AU/T, 0.54% CU AND 0.66%SN) AT ISKA ISKA SILVER-TIN POLYMETALLIC PROJECT, POTOSI DEPARTMENT, BOLIVIA

Eloro Resources Ltd. has provided an update on its Iska Iska silver-tin polymetallic project in the Potosi department, southern Bolivia. To date, the Company has completed 35,738 metres (m) in 68 drill holes including three (3) in progress to test major target areas at Iska Iska. This press release reports drilling results from one (1) additional hole which tested the Porco Breccia Pipe ("PBP") (Hole DPC-01) and new underground channel sampling from the Porco adit located approximately 200m south of the PBP. Currently three drill rigs are in operation at Iska Iska. Two surface drill rigs are continuing to drill at the Santa Barbara Resource Definition Target Zone (Figure 1) to outline an initial National Instrument 43-101 ("NI-43-101") compliant resource. A third drill, an underground rig, situated in the west end of the Santa Barbara Adit, is testing the eastern part of Santa Barbara Breccia Pipe ("SBBP') and its mineralized envelope. Figure 1 is a geological plan map showing locations of drill holes completed, in progress and planned to complete resource definition drilling along with an updated geological interpretation. Figure 2 is a plan map of channel sampling at the Porco adit. Table 1 provides significant drilling results with definitions of chemical symbols, Table 2 details channel sample results from the Porco adit and Table 3 lists holes completed with assays pending, as well as holes in progress in the three major target areas. Highlights include:

Porco Adit

Channel sampling in the Porco adit returned 521.33 g Ag eq/t (including 117.10 g Ag/t, 1.44 g Au/t, 0.54% Cu and 0.66% Sn) over a 103m strike length with an average channel width of 1.8m as shown in Figure 2 and Table 2. Mineralization in the Porco adit is hosted in a series of veins, veinlets, stockworks and disseminations in Ordovician quartz sandstone. The veins are parallel to and crosscutting the drift. In the western part of the drift veins are primarily sulphide-bearing whereas those in the eastern half are primarily oxide. Eloro believes mineralization at the Porco adit is sourced from a large underlying porphyry system as evidenced by recently acquired magnetic susceptibility data.

Porco Breccia Pipe

Hole DCP-01 drilled due west at -65 degrees from the Porco radial platform intersected sixteen (16) separate zones of quartz-tourmaline veins in granodioritic intrusive breccia with best results of 110.30 g Ag eq/t over 3.0m,67.08 g Ag eq/t over 6.0m including 168.25 g Ag eq/t (25.0 g Ag/t, 1.31% Zn, 0.32% Pb and 0.25% Sn) over 1.54m, 131.16 g Ag eq/t (18 g Ag/t, 0.54% Cu and 0.31% Bi) and 80.66 g Ag eq/t over 3.0m (0.23% Sn).

Figure 3 is a longitudinal section (A-A' in Figure 1) showing the inverse model of magnetic susceptibility which highlights major targets and geological features. Figure 4 is a 3D view of the inversion model showing that Hole DPC-01 just clipped the edge of a very strong and extensive magnetic susceptibility anomaly below and to the northwest of the PBP. The strongest part of the anomaly, as shown in Figure 5, a cross section along drill hole DPC-01 (B-B' in Figure 1), is located just to the northwest of this hole in the very prospective gap area between the Central Breccia Pipe and the PBP (see Figure 1). Further drilling is planned to test this target once definition drilling at the Santa Barbara Resource Definition Target Zone is completed.

Definition Drilling Santa Barbara Target Area

Definition drilling is continuing in the Santa Barbara Resource Definition Target Zone as shown in Figure 1. Currently a series of SW-NE sections at approximately 100m intervals are being completed with holes drilled on each section at -40 degrees and 65 degrees to provide coverage over the full target strike length of 1,400m. Underground drilling is continuing in the Santa Barbara adit to evaluate the resource potential in the mineralized envelope east of the SBBP. It is anticipated that the definition drilling program will be completed by early December. Drilling will then refocus on exploration of the major magnetic targets in the Central-Porco target area as outlined above.

Dr. Bill Pearson, P.Geo., Eloro's Executive Vice President Exploration, added: "The magnetic data have proven invaluable in outlining the overall extent of the massive porphyry-epithermal system at Iska Iska. The higher-grade mineralized zones at Iska Iska tend to be magnetic hence the areas with high magnetic response are very prospective targets. Our geophysical team is also currently processing the downhole IP data from the Santa Barbara Resource Definition Target Zone which should help to better define the overall extent of mineralization especially zones with higher sulphide content which are generally higher grade."

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro`s Bolivian subsidiary, Minera Tupiza S.R.L. ("Minera Tupiza"), said: "The mineralization in the Porco adit is interpreted to be the lower part of the high sulphidation epithermal system which is likely connected to a major tin porphyry at depth as suggested by the extensive magnetic susceptibility anomaly. The intersections in Hole DPC-01 which are most abundant where this hole clipped the magnetic susceptibility anomaly are tin-rich supporting this conclusion. Our work continues to expand the remarkable mineralized system at Iska Iska which has now been shown to be at a district-scale."

Dr. Quinton Hennigh, P.Geo., Eloro's Senior Technical Advisor, commented: "The return of impressive polymetallic grades from the Porco adit confirm that the Iska Iska mineral system extends a remarkable 2.5 km from north to south. Metal endowments display notable zonation along this corridor from Ag-Zn-Pb-rich in the north to Ag-Sn-rich in the middle to Ag-Sn-Cu-Au-rich in the south. This is likely a reflection of proximity to the underlying source porphyry believed to be situated along the southern margin of the caldera complex as evidenced by recently collected magnetic data. The southern part of the Iska Iska system shows great potential for further discovery. It will be exciting to see drilling resume in this area."
