Eloro Intersects 129.65 g Ag eq/t over 300.75m in the Mineralized Envelope of the Santa Barbara Breccia Pipe at the Iska Iska Silver-Tin Polymetallic Project, Potosi Department, Bolivia

Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF FSE: P2QM) (“Eloro”, or the “Company”) is pleased to provide an update on its Iska Iska silver-tin polymetallic project in Potosi Department, southern Bolivia. To date, the Company has completed 46 diamond drill holes totalling 22,398.9 metres (m) to test major target areas at Iska Iska. This press release reports drilling results from four (4) additional holes which tested the mineralized envelope of the Santa Barbara Breccia Pipe (“SBBP”) and the central-southern part of the Central Breccia Pipe (“CBP”). To date, every drill hole that has been assayed has returned multiple reportable mineralized intercepts. Currently three drill rigs are in operation at Iska Iska. One surface drill rig is completing first pass drilling of the major Porco (South) Target. The second surface drill is currently cleaning out drill holes on the SBBP radial platform for the planned downhole induced polarization/resistivity (IP/RES) survey then will be moved to test the gap area between the Central and Porco Breccia Pipes. The third drill, an underground rig, is testing the northeast part of SBBP and its mineralized envelope. This drill will shortly be moved to a new drill bay recently completed on the west end of the Santa Barbara adit. Figure 1 is a geological plan map showing locations of drill holes and an updated geological interpretation. Figure 2 is a more detailed geological plan map of the SBBP and northern CBP areas showing the magnetic low target to the northwest of the SBBP where drilling is planned (see press release June 7, 2021 for an overview of the magnetic results). Table 1 provides significant drilling results and Table 2 lists holes completed with assays pending as well as holes in progress in the three major target areas. Highlights are as follows:

Highlights:

• Hole DHK-18, drilled due south at -10 degrees from the west drill bay in the Huayra Kasa underground workings to test the mineralized envelope of the SBBP, intersected 129.65 g Ag eq/t (18.38 g Ag/t, 2.14% Zn, 0.67%Pb, and 0.047% Sn) over 300.75m from 65.14m to 365.91m. This includes higher grade intervals of 215.54 g Ag eq/t over 72.76m, 163.35 g Ag eq/t over 31.83m and 224.48 g Ag eq/t over 19.39m. This hole intersected significant mineralization approximately 230m below the eastern part of the Santa Barbara adit from which continuous channel sampling previously reported returned 442 g Ag eq/t over 166m (see press release April 13, 2021). 82% of this 446.5m long hole contained reportable intervals;
• Hole DSB-11, drilled to the southeast at -40 degrees from the SBBP radial centre to test the area approximately 300m below the Santa Barbara adit intersected 121.90 g Ag eq/t (40.27g Ag/t, 0.10 g Au/t 0.48% Pb, 0.11% Cu and 0.14% Sn) over 137.4m from 190.02m to 327.36m. This includes a higher-grade interval grading 173.53 g Ag eq/t over 80.54m. Notable intercepts lower in the hole include 76.59 Ag eq/t over 55.9m from 407.60m to 463.51m including a higher-grade section of 105.56 g Ag eq/t over 33.31m and 78.82 g Ag eq/t over 143.03m from 520.7m to 773.73m including 105.48 g Ag eq/t over 34.82m and 120.70 g Ag/t over 19.54m. Overall 61% of this 665.3m hole contains reportable intersections.
• Hole DCS-01 drilled due east at -60 degrees was the first reconnaissance hole drill from the south radial platform on CBP. This hole, which was drilled to 1,007.5m, intersected 25 reportable Ag-Zn-Pb-Sn mineralized intervals ranging in size from 1.43m to 34.86m from the start of the hole to its end. Best results include 87.75 g Ag eq/t over 21.67m, 161.07 g Ag eq/t over 13.25m, 100.60 g Ag eq/t over 15.15m, 54.44 g Ag eq/t over 34.86m, 90.24 g Ag eq/t over 26.91m and 117.48 g Ag eq/t over 16.51m.
• Hole DCN-03 was drilled southeast at -60 degrees from the northern radial platform of the CBP. This hole intersected nine mineralized intersections principally Sn-Ag over its 464.5m length. The best result was 48.59 g Ag eq/t (16.23 g Ag/t, 0.12% Pb and 0.064% Sn) over 15.05m.

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, commented: “We are close to completing first pass drilling over three of our major target areas in the Iska Iska Caldera Complex. Following completion of the downhole IP/Res survey, we will be carrying out additional drilling in the SBBP and its surrounding envelope to define the full extent of mineralization which remains open in all directions. This drilling will also test the potential extension of the mineralized zone to the northwest as indicated by the strong magnetic low as shown in Figure 2. Hole DCS-01 intersected silver-tin polymetallic mineralization similar to what we are seeing visually in the initial drill holes on Porco. Analysis of the magnetic data suggests the potential for a centre of mineralization in the gap zone between CBP and Porco; this will be drill tested soon. The northern part of CBP is primarily an Sn target with some Ag. We will determine the follow-up drill plan there once we receive pending assays from the drill holes. Our Tupiza-based exploration team led by Dr. Osvaldo Arce, P.Geo. continues to do an excellent job keeping up with all the drilling and we thank our drill contractor Leduc Drilling for the continuing high quality drill production.”

Dr. Quinton Hennigh, Senior Technical Advisor to Eloro stated: “The 300.75m intercept grading 129.65 g Ag eq/t in hole DHK-18 generates a metal factor of approximately 39,000 gram-meters Ag eq/t, a remarkable result and a clear testament to the strength of the Iska Iska Ag-Sn-base metal system. For those more familiar with gold, this grade is equivalent to almost 2 g Au eq/t over 300.75m. Importantly, mineralization occurs in the wall rock envelope east of the SBBP, thus the system is not constrained to the limits of the breccia pipes. All holes drilled across the project to date display intervals of alteration and mineralization, and the limits of the system have not yet been delineated. In short, all geologic settings, either in or out of the breccia pipes, can be considered prospective, and the deposit is wide open for expansion in all directions. We have lots to look forward to as results return from multiple outstanding holes including those recently completed at Porco (South).”

Note: True width of the mineralization is not known at the present time, but based on the current understanding of the relationship between drill orientation/inclination and the mineralization within the breccia pipes and the host rocks such as sandstones and dacites. It is estimated that true width ranges between 70% and 90% of the down hole interval length but this will be confirmed by further drilling. Percentage metal contents are shown for each element.

Chemical symbols: Ag= silver, Au = gold, Zn = zinc, Pb = lead, Cu = copper, Sn = tin, Bi = bismuth, Cd = cadmium and g Ag eq/t = grams silver equivalent per tonne. Quantities are given in percent (%) for Zn, Pb Cu, Sn, Bi and Cd and in grams per tonne (g/t) for Ag, Au and Ag eq.

Metal prices and conversion factors used for calculation of g Ag eq/t (grams Ag per grams x metal ratio) are as follows:

In calculating the intersections reported in this press release a sample cutoff of 30 g Ag eq/t was used with generally a maximum dilution of 3 continuous samples below cutoff included within a mineralized section unless more dilution is justified geologically.

Total drilling completed since the start of the program on September 13, 2020 is 22,398.9m in 46 holes (18 underground holes and 28 surface holes) with one underground and one surface hole in progress. The second surface drill is cleaning out holes for the downhole IP survey.

Qualified Person

Dr. Osvaldo Arce, P. Geo., General Manager of Eloro’s Bolivian subsidiary, Minera Tupiza S.R.L., and a Qualified Person in the context of National Instrument 43-101 (“NI 43-101”), has reviewed and approved the technical content of this news release. Dr. Bill Pearson, P.Geo., Executive Vice President Exploration Eloro, and who has more than 45 years of worldwide mining exploration experience including extensive work in South America, manages the overall technical program working closely with Dr. Arce. Dr. Quinton Hennigh, P.Geo., Senior Technical Advisor to Eloro and Independent Technical Advisor, Mr. Charley Murahwi P. Geo., FAusIMM of Micon International Limited are regularly consulted on technical aspects of the project.

Drill samples are prepared in ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia with pulps sent to the main ALS Global laboratory in Lima for analysis, As announced in the February 26, 2021 press release, Eloro has changed the assay protocol to utilize X-ray fluorescence (XRF) to more accurately analyze higher Sn. Tin in the CBP is suspected to occur as cassiterite which is insoluble in acid digestion, and therefore not suited for wet chemical techniques. In addition, other assay protocols have been changed to provide for a more accurate measurement of the wide-ranging suite of polymetallic metals at Iska Iska. Eloro employs an industry standard QA/QC program with standards, blanks and duplicates inserted into each batch of samples analyzed with selected check samples sent to a separate accredited laboratory.

Unfortunately, the ALS Global laboratory in Lima where the Iska Iska samples are being analyzed has had major delays in turnaround time due to the impact of the COVID-19 lockdown of Lima by the Peruvian government. This has restricted availability of critical supplies necessary to carry out analytical work. As a result, there will be delays in reporting of assay results.

About Iska Iska

Iska Iska silver-tin polymetallic project is a road accessible, royalty-free property, wholly-controlled by the Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km north of Tupiza city, in the Sud Chichas Province of the Department of Potosi in southern Bolivia. Eloro has an option to earn a 99% interest in Iska Iska.

Iska Iska is a major silver-tin polymetallic porphyry-epithermal complex associated with a Miocene possibly collapsed/resurgent caldera, emplaced on Ordovician age rocks with major breccia pipes, dacitic domes and hydrothermal breccias. The caldera is 1.6km by 1.8km in dimension with a vertical extent of at least 1km. Mineralization age is similar to Cerro Rico de Potosí and other major deposits such as San Vicente, Chorolque, Tasna and Tatasi located in the same geological trend.

Eloro began underground diamond drilling from the Huayra Kasa underground workings at Iska Iska on September 13, 2020. On November 18, 2020 Eloro announced the discovery of a significant breccia pipe with extensive silver polymetallic mineralization just east of the Huayra Kasa underground workings and a high-grade gold-bismuth zone in the underground workings. On November 24, 2020, Eloro announced the discovery of the Santa Barbara Breccia Pipe (“SBBP”) approximately 150m southwest of the Huayra Kasa underground workings.

Subsequently, on January 26, 2021, Eloro announced significant results from the first drilling at the SBBP including the discovery hole DHK-15 which returned 129.60 g Ag eq/t over 257.5m (29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu, 0.056%Sn, 0.0022%In and 0.0064% Bi from 0.0m to 257.5m. Subsequent drilling has confirmed significant values of Ag-Sn polymetallic mineralization in the SBBP and the adjacent Central Breccia Pipe (“CBP”). The SBBP thus far extends 800m along strike by 400+m wide and extends to at least 700m depth. CBP extends for 700m along strike by 400+m wide and extends to at least 900m deep.

A substantive mineralized envelope which is open along strike and down-dip extends around the breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 gAg/t, 0.46%Sn, 3.46% Pb and 0.14% Cu) over 166m including 1,092 g Ag eq/t (446 g Ag/t, 9.03% Pb and 1.16% Sn) over 56.19m. The west end of the adit intersects the end of the SBBP.

On May 4, 2021, Eloro released results from the first drill hole on the CBP. Hole DCN-01 intersected multiple mineralized intercepts including 196.09 g Ag eq/t (150.25 g Ag/t, 0.10% Sn and 0.05 g Au/t) over 56.2m and containing 342.98 g Ag eq/t (274.0 g Ag/t, 0.16% Sn and 0.16 g Au/t) over 27.53m.

On May 26, 2021 Eloro released results from Hole DSB-07 drilled at -60 degrees to a depth of 683.4m to the southeast from the radial drill platform on SBBP which intersected multiple mineralized intercepts including:

• 122.66 grams silver equivalent/tonne (“g Ag eq/t”) (35.05 g Ag/t, 0.72% Zn, 0.61% Pb, 0.11% Sn and 0.06 g Au/t) over 123.61m from 236.60m to 360.21m including 205.74 g Ag eq/t (92.30 g Ag/t, 0.57% Zn, 0.85% Pb, 0.18% Sn and 0.07 g Au/t) over 32.32m, from 317.21m to 349.53m.
• 105.41 g Ag eq/t (8.55 g Ag/t, 1.01% Zn, 0.48% Pb, 0.06% Sn and 0.38 g Au/t) over 173.58m from 449.87m to 623.45m including 199.77 g Ag eq/t (21.90 g Ag/t, 1.18% Zn, 0.93% Pb 0.12% Sn and 0.94 g Au/t) over 39.08m, from 551.19m to 590.27m.
• 146.19 g Ag eq/t (1.70 g Ag/t, 0.00% Zn, 0.01% Pb, 0.42% Sn and 0.02 g Au/t) over 10.20m from 171.60m to 181.80m in the oxide zone indicating potential for significant Sn mineralization in this strongly leached nearer surface zone.
• In aggregate, 64% of this 683.4m long hole returned reportable mineralized intervals.

Eloro Resources reported additional multiple holes with significant silver-tin polymetallic Intercepts in the Santa Barbara and Central Breccia Pipes on July 6, 2021 including:

• Hole DSB-08, testing the northeast quadrant of the SBBP, encountered eighteen reportable mineralized intercepts beginning near surface to its terminus at 614.4 m. The longest intercept was 69.89 g Ag eq/t over 252.89m from 355.12 to 608.02m including several higher-grade sections of 196.60 g Ag eq/t including 131.13 g Ag/t over 14.52m, 134.62 g Ag eq/t including 93.25 g Ag/t over 21.08m and 145.35 g Ag eq/t including 2.38% Zn over 10.11m.
• Hole DSB-10, testing the southwest quadrant of the SBBP and northern part of the CBP, encountered twenty-nine reportable mineralized intercepts beginning near surface to its terminus at 1,019.4m. Tin was notably elevated in many intervals suggesting proximity to a mineralizing intrusive source in this area. Notable intercepts include 114.96 Ag eq/t including 0.325% tin (Sn) over 56.2m from 322.18m to 378.30m including a higher-grade section of 187.98 g Ag eq/t including 0.535% Sn over 28.86m, 80.71 g Ag eq/t including 0.213% Sn over 74.39m from 474.86 to 549.25m and 118.69 g Ag eq/t over 10.77m from 829.97 to 840.74m.

A detailed ground magnetic survey of the Iska Iska property reported on June 6, 2021 confirmed the extent of the Iska Iska Caldera as determined from geological mapping and satellite interpretation including Aster data. The Santa Barbara and Central Breccia Pipes, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the that the Central and Porco Breccia Pipes likely merge at depth. There is a prominent area of low intensity magnetics northwest of the Santa Barbara Breccia Pipe which requires follow-up work.

Geological mapping and satellite interpretation identified a third major breccia pipe target Porco (South) that is approximately 600m in diameter (South) located southeast of CBP in the southern part of the Iska Iska caldera complex. The Porco (South) Breccia Pipe target has a similar magnetic signature to the Santa Barbara and Central Breccia Pipes, further confirming the likelihood of it being a major breccia pipe. This target is currently being drill tested. Previous channel sampling in the Porco adit located adjacent the target area 200m to the southeast returned 50m grading 519.35 g Ag eq/t including 236.13 g Ag/t, 1.89 g Au/t, 0.87% Cu, 0.22% Bi and >0.05% Sn over an average sample width of 2.49m.

Currently three diamond drill rigs are active at Iska Iska, two surface rigs and one underground drill. Planned drilling for 2021 is 51,000m with the aim of outlining an initial inferred NI 43-101 mineralization by late fall. A a downhole induced polarization/resistivity survey is in progress to further define drill targets and aid resource definition drilling. Preliminary metallurgical tests are also in progress. An updated NI 43-101 Technical Report is being prepared by independent consultant Micon International Ltd.
