Eloro Resources' Deep Hole DSBS-02 Encounters Numerous Mineralized Intercepts Including 146.65 g Ag eq/t (10.74 g Ag/t, 1.01 g Au/t, 0.31% Zn, 0.11% Pb and 0.06% Sn) over 88.66m and 131.86 g Ag eq/t (21.38 g Ag/t, 0.06 g Au/t, 0.25% Zn, 0.24% Pb and 0.14% Sn) over 104.38m in the Santa Barbara Target Area at the Iska Iska Silver-Tin Polymetallic Project, Potosi Department, Bolivia

• Hole DSBS-02 was drilled across the interpreted Santa Barbara feeder zone to a length of 1,023.4m, corresponding to a vertical depth of 745m. Notably, 67% of the overall length of this hole yielded reportable intersections which collectively average 100.42 g Ag eq/t.
  
  
• Grade shell modelling in Leapfrog of the Santa Barbara Deposit indicates that, as of this date, drilling has defined a higher-grade zone >90 g Ag eq/t that is approximately 750m along strike, 650m wide and extends to a depth of at least 750m. This deposit remains open in all directions.
• Hole DPC-09, the first of a series of holes to test the major inverse magnetic susceptibility anomaly in the Porco area, intersected 41 reportable mineralized intersections representing 29% of this 1,124.4m long hole that collectively average 94.73 g Ag eq/t. Significantly, the last reportable intersection near the bottom of this hole is higher in Ag and Sn with very low values of Zn and Pb. This is typical of what is seen in the Santa Barbara area in the transition from the Ag-Zn-Pb-Sn polymetallic mineralization to the more tin dominant mineralization at depth.
• The coincidence of the magnetic inverse model with the chargeability/conductivity model from Bore Hole Induced Polarization (BHIP) surveys provides a powerful tool to outline very prospective drill targets. BHIP surveys to a depth of almost 1,000m show that the conductivity increases with depth at Santa Barbara, indicating that the potential feeder zone could be even more substantive.

TORONTO, June 14, 2022 (GLOBE NEWSWIRE) -- Eloro Resources Ltd. (TSX-V: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce assay results from an additional two (2) diamond drill holes from its on-going drilling program at the Iska Iska silver-tin polymetallic project in the Potosi Department, southern Bolivia. Hole DSBS-02 is a surface hole drilled due north at -300 from the south side of Santa Barbara across the higher-grade likely feeder zone. Hole DPC-09 is the first in a series of drill holes to test the extensive magnetic susceptibility anomaly in the Porco area in the southern part of the property. Four drills including three surface drills and one underground drill are focussed on completing drilling in the Santa Barbara Resource Definition Drilling Area. The underground drill is on its last hole and will be moved to surface to complete drill holes requested by Micon International Limited (“Micon”) to better define the preliminary open pit to be utilized for the maiden mineral resource estimate targeted for completion at the end of Q3.

Overall, the Company has completed 59,499m in 95 drill holes to-date, including four holes in progress, as shown in Figure 1. Tables 1 and 2 list significant assay results for the two drill holes reported. Prices used for calculating Ag equivalent grades are as outlined in Eloro’s February 1, 2022, press release. Table 3 summarizes drill holes with assays pending. Highlights are as follows:

Santa Barbara Mineral Resource Definition Target Area – Surface Drilling

Hole DSBS-02 was collared in the south part of the Santa Barbara target at an azimuth of 00 and dip of -300 to test across the likely higher grade feeder zone for the Santa Barbara Ag-Sn polymetallic mineralization. This hole was drilled to a length of 1,023.4m, corresponding to a vertical depth of 745m, with 67% of the hole containing reportable intersections which collectively average 100.42 g Ag eq/t. Significant results are as follows:

• 146.65 g Ag eq/t (10.74 g Ag/t, 1.01 g Au/t, 0.31% Zn, 0.11% Pb and 0.06% Sn) over 88.66m from 319.36m to 408.02m, including a higher-grade section of:
  
  • 737.33 g Ag eq/t (51.11 g Ag/t, 6.82 g Au/t, 0.24% Zn, 0.31% Pb, and 0.19% Sn) over 12.06m from 355.39m to 367.45m. Notably, this is the strongest gold-bearing intercept encountered to date at Iska Iska.
• 131.86 g Ag eq/t (21.38 g Ag/t, 0.06 g Au/t, 0.25% Zn, 0.24% Pb and 0.14% Sn) over 104.38m from 531.22m to 635.60m, including higher-grade sections of:
  
  
  • 224.16g Ag eq/t (50.19 g Ag/t, 0.02 g Au/t, 0.41% Zn, 0.38% Pb and 0.24%Sn) over 26.79m from 543.09 to 569.88,
  • 300.90g Ag eq/t (35.33 g Ag/t, 0.20 g Au/t, 0.26 % Zn. 0.78% Pb and 0.36% Sn) over 10.38m from 590.84m to 601.22m.
• 78.94 g Ag eq/t (12.77 g Ag/t, 0.06 g Au/t, 0.66% Zn, 0.12% Pb and 0.04% Sn) over 235.43m from 670.27m to 905.70m which included higher grade sections of:
  
  
  • 494.81 g Ag eq/t (170.06 g Ag/t, 0.49 g Au/t, 0.37% Zn, 0.35 %Pb, 0.40 % Sn) over 4.46m from 722.70m to 727.16m,
  • 181.64 g Ag eq/t (76.79 g Ag/t, 0.19g Au/t, 0.76% Zn, 0.23 %Pb and 0.07% Sn) over 4.35m from 770.73m to 775.08m,
  • 120.54 g Ag eq/t (15.50g Ag/t, 0.01 g Au/t, 1.57% Zn, 0.34% Pb and 0.03%Sn) over 10.96 m from 800.44m to 811.40m, and
  • 129.54 g Ag eq/t (6.44 g Ag/t, 0.08 g Au/t, 2.03% Zn, 0.34% Pb and 0.02% Sn) over 8.94 m from 853.28m to 862.22m.

Dr. Bill Pearson, P.Geo. Eloro’s Executive Vice President, Exploration commented: “Grade shell modelling in Leapfrog of the Santa Barbara Deposit by the Iska Iska geological team indicates that drilling has defined a higher-grade zone >90 g Ag eq/t that extends approximately 750m along strike, is 650m wide and extends to a depth of at least 750m. The deposit is open in all directions. Figure 2 shows the Santa Barbara deposit model relative to the extensive 3D inverse magnetic susceptibility model, demonstrating the remarkable scale of this enormous mineralized system.”

Dr. Pearson continued: “Figure 3 is a 3D model combining the inverse magnetic susceptibility model and the bore hole induced polarization (“BHIP”) chargeability and conductivity data that clearly shows how this new hole DSBS-02 intersected significant mineralization in an area of an extensive chargeability anomaly coincident with a magnetic high. In the lower part of this hole conductivity increases substantially and indicates that this hole stopped just short of a likely area of massive sulphide mineralization. The coincidence of the magnetic inverse model with the chargeability/conductivity model provides a powerful tool to outline very prospective drill targets. BHIP surveys to a depth of almost 1,000m show that the conductivity increases with depth at Santa Barbara, indicating that the potential feeder zone could be even more substantive.”

Dr. Chris Hale, P.Geo., Chief Geophysicist for Eloro said: “Geophysical targeting is very useful at Iska Iska because the mineralization often occurs in association with pyrrhotite, a mineral that affects both the electrical and magnetic properties of the host rock. BHIP helps to correlate mineralization between the holes because it samples a much larger volume around the borehole than each assay does. BHIP provides two electrical measures of the quantity of mineralization; chargeability that measures the amount of disseminated mineralization and conductivity that shows when the strength of mineralization reaches the point of “connectivity”, resulting in a conductive deposit. This explains the strong spatial correlation between the grade of mineralization and the chargeable volume around DSBS-02. We do not yet have BHIP surveys under DPC-09 but this hole was targeted to test a peak in the magnetic susceptibility that was modelled using surface magnetic data. The excellent spatial coincidence between the mineralized intersection and the peak in magnetic susceptibility gives us confidence that we will also likely intersect mineralization when we drill the larger magnetic susceptibility zone that is modelled deeper and farther to the south.”

Porco Area – Magnetic Inverse Anomaly – Surface Drilling

Hole DPC-09 is the first of a series of holes to test the major inverse magnetic susceptibility anomaly in the Porco area, as outlined in Eloro’s March 1, 2022 press release. This hole intersected 41 reportable mineralized intersections, representing 29% of this 1,124.4m long hole that collectively averaged 94.73 g Ag eq/t. Highlights include:

• 143.47 g Ag eq/t (10.67 g Ag/t, 0.25 g Au/t, 1.90 % Zn, 0.23%Pb, 0.09% Cu and 0.01% Sn) over 11.96m from 363.57 to 375.53m
• 84.46 g Ag eq/t (6.52 g Ag/t, 0.03 g Au/t, 1.13% Zn, 0.37% Pb and 0.01% Sn) over 10.63m from 410.09 to 420.72m
• 79.46 g Ag eq/t (4.47 g Ag/t, 0.02 g Au/t, 1.12% Zn, 0.08 %Pb and 0.03 % Sn) over 42.55m from 740.63m to 783.18m.
• 82.64 g Ag eq/t (3.48 g Ag/t, 0.05 g Au/t, 0.50% Zn, 0.09% Pb, and 0.08% Sn) over 57.34m from 798.15m to 855.49m including a higher grade section of:
  
  
  • 127.94 g Ag eq/t (3.37 g Ag/t, 0.05 g Au/t, 0.50% Zn,0.12% Pb and 0.16% Sn) over 12.02m from 798.15 to 810.17m,
• 96.13 g Ag eq/t (8.14 g Ag/t, 0.15 g Au/t, 0.40% Zn, 0.11% Pb and 0.09% Sn) over 14.83m from 972.51m to 987.34m,
• 69.88 g Ag eq/t (8.73 g Ag/t, 0.11 g Au/t, 0.22% Zn, 0.05% Pb and 0.06% Sn) over 40.24m from 1045.82m to 1086.06m including a higher grade section of
  
  
  • 100.05 g Ag eq/t (16.71 g Ag/t, 0.08 g Au/t, 0.35% Zn, 0.06% Pb and 0.09% Sn) over 13.25m from 1068.37 to 1081.62m
• 163.35 g Ag eq/t (48.35 g Ag/t, 0.12 g Au/t, 0.05% Zn, 0.05% Pb, 0.09% Cu and 0.15% Sn) over 5.95m from 1114.63m to 1120.58m
  

As shown in Figure 4, this hole intersected a very extensive inverse magnetic susceptibility anomaly which, at elevation 3,400m, extends for approximately 1.6km along strike by 700m wide with a vertical extent of approximately 750m. The 3,400m elevation is approximately 100m above the valley floor. Significantly, the last reportable intersection near the bottom of the hole is higher in Ag and Sn with very low values of Zn and Pb. This is typical of what is seen in the Santa Barbara area in the transition from the Ag-Zn-Pb-Sn polymetallic mineralization to the more tin dominant mineralization at depth.

Definition Target Area as at June 14, 2022.

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 and geological modelling.

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 (Prices updated as of February 1, 2022, to more accurately reflect current metal prices):

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.

The equivalent grade calculations are based on the stated metal prices and are provided for comparative purposes only, due to the polymetallic nature of the deposit. Metallurgical tests are in progress by Blue Coast Ltd. to establish levels of recovery for each element reported but currently the potential recovery for each element has not yet been established. While there is no assurance that all or any of the reported concentrations of metals will be recoverable, Bolivia has a long history of successfully mining and processing similar polymetallic deposits which is well documented in the landmark volume “Yacimientos Metaliferos de Bolivia” by Dr. Osvaldo R. Arce Burgoa, P.Geo.

Eloro is utilizing both ALS and AHK for drill core analysis, both of whom are major international accredited laboratories. Drill samples sent to ALS are prepared in both ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia and the preparation facility operated by AHK in Tupiza with pulps sent to the main ALS Global laboratory in Lima for analysis. More recently Eloro has had ALS send pulps to their laboratory at Galway in Ireland. 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.

Drill core samples sent to AHK Laboratories are prepared in a preparation facility installed and managed by AHK in Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Au and Sn analysis on these samples is done by ALS Bolivia Ltda in Lima. Check samples between ALS and AHK are regularly done as a QA/QC check. AHK is following the same analytical protocols used as with ALS and with the same QA/QC protocols. Turnaround time continues to improve, as laboratories return to more normal staffing levels.

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 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 CBP. A substantive mineralized envelope which is open along strike and down-dip extends around both major breccia pipes. Continuous channel sampling of the Santa Barbara Adit located to the east of SBBP returned 442 g Ag eq/t (164.96 g Ag/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.

Since the initial discovery hole, Eloro has released a number of significant drill results in the SBBP and the surrounding mineralized envelope which along with geophysical data has defined a target zone 1400m along strike, 500m wide and that extends to a depth of 600m. This zone is open along strike to the northwest and southeast as well as to the southwest. The Company’s nearer term objective is to outline a maiden NI 43-101 compliant mineral resource within this large target area. This work is advancing well with the mineral resource targeted to be completed in Q3 2022. Exploration drilling is also planned on other major targets in the Iska Iska Caldera Complex, including the Porco and Mina 2 areas.
