Eloro Resources (ELO.V): Announces Restart of Diamond Drilling and Provides Update on Iska Iska Silver-Tin Polymetallic Project, Potosi Department, Bolivia

TORONTO, Jan. 18, 2022 (GLOBE NEWSWIRE) — 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 the Potosi Department, southern Bolivia. By the end of 2021, the Company completed 40,468 metres (m) in 73 drill holes at Iska Iska, as shown in Figure 1. Table 1 summarizes drill holes with assays pending. Currently there are two surface drill rigs and one underground drill rig on site. Drilling with all rigs recommenced on January 17, 2022. Highlights of work in progress are as follows:

• Definition drilling has been substantially completed over the Santa Barbara target zone which extends for over a strike length of approximately 1,400m, across a width of 500m and to a depth of 600+m. All drill holes in the Northwest Extension intersected significant mineralization confirming that the Santa Barbara mineralization extends across the full 1,400m long resource definition target zone. The mineralized system remains open along strike to the northwest and southeast as well as to the southwest.
• More assay results are expected to be released in the next 2-3 weeks, but further delays have been experienced due to the impact of Covid-19 on staffing at the laboratories. All drill core completed prior to shutdown of drilling on December 17, 2021, has been logged, sawn and sampled with samples shipped to the laboratories.
• The Iska Iska caldera complex, which we now know has both a main caldera and two nested secondary calderas, extends along strike in a northwest-southeast direction for at least 2.5km, a width of at least 2km and likely extends to a depth of more than 1km.
• Going forward exploration drilling will be focused on testing the major targets in the Porco and Mina 2 areas along with the potential for a tin porphyry at depth. We are working closely with Micon International Limited to facilitate the National Instrument (“NI”) 43-101 mineral resource estimation process which we are now targeting to be completed in Q2 2022.

Tom Larsen, CEO of Eloro commented: “The last two years have proven to be Eloro’s most transformative and exciting to date. Our decision in 2019 to pursue a new mineral resource project, which resulted in the January 2020 signing of the Iska Iska silver-tin polymetallic property option agreement, has proven to be the catalyst for the Company’s upward trajectory and promising future. In just 15 months since the start of diamond drilling, Iska Iska has advanced from a promising grass roots project to being on the verge of outlining a significant NI 43-101 compliant mineral resource. Under the leadership of Dr. Osvaldo Arce, P. Geo., our in-country General Manager, and Dr. Bill Pearson, P, Geo., our Executive Vice President Exploration, we have built a very strong in-country technical team based in Tupiza, Bolivia. This team is supported by several excellent local contractors including Leduc Drilling who have completed more than 40,000 metres of diamond drilling since we started. As outlined in this update, we have a tremendous amount of work in progress, which will lead to the inaugural mineral resource, confirmation of metallurgical recoveries and drill-testing of more major targets in this remarkable mineralized system.”

Dr. Bill Pearson, P.Geo., Eloro’s Executive Vice President Exploration, added: “Work is progressing well on completing an updated geological model for the Santa Barbara Target Zone. The bore hole induced polarization (IP) survey results are being processed and the resulting 3D inverse model should help in determining the internal geometry of the deposit, especially of higher sulphide zones, which generally have the best grades. We are working closely with Micon International Limited to facilitate the mineral resource estimation process which we are now targeting to be completed in Q2 2022. Both the ALS and AHK Laboratories are working to reduce the backlog of samples waiting for analysis, however, the recent surge in Covid has created staffing issues for the laboratories, hence there may be further delays in receiving assay results although it is expected that more results will be available for release in the next 2-3 weeks. Definition drilling on our 1,400m by 500m wide by 600m deep mineral resource definition target zone in Santa Barbara is almost complete with the final two holes to be completed in the next two weeks. All drill core completed prior to shutdown of drilling on December 17, 2021 has been logged, sawn and sampled with samples shipped to the laboratories. Going forward exploration drilling will be focused on testing the major targets in the Porco and Mina 2 areas along with the potential for a tin porphyry at depth.”

Dr. Osvaldo Arce, P.Geo., General Manager of Eloro`s Bolivian subsidiary, Minera Tupiza S.R.L. (“Minera Tupiza”), said: “The Iska Iska silver-tin polymetallic deposit is hosted in Miocene breccia pipes, dacitic domes as well as granodiorite stocks and Ordovician sandstones, but especially in the breccia pipes. These breccia pipes were formed by explosive fluids derived from a large magmatic plumbing system, likely comparable to several major deposits in southern Bolivia. Such as Chorolque, Tasna, Tatasi, Chocaya and Siete Suyos. However, in contrast to these other deposits, the Iska Iska system shows a uniqueness of preservation due to the intense and ubiquitous silicification that affects all rocks but especially those with closer proximity to the vents marked by the breccia pipes. The basement Ordovician quartz sandstones are also very erosionally resistant. The combination of the silicification and erosionally resistant basement has preserved an almost complete volcanic edifice at Iska Iska which extends 1km vertically from the valley floor. We now know that the Iska Iska caldera complex consists of a large main caldera covering an area of approximately 1.6km by 1.8km with two nested secondary calderas approximately 1.2 km by 1.0 km in the northwest and approximately 800m in diameter in the southeast as shown in Figure 1. The Iska Iska caldera complex extends along strike in a northwest-southeast direction for at least 2.5km, a width of at least 2km and likely extends to a depth of more than 1km. Iska Iska was not discovered historically because of extensive leaching of metals at surface forming a very depleted oxide zone barren of metals.”

Definition Drilling Santa Barbara Target Area

Definition drilling in the Santa Barbara Mineral Resource Definition Drilling Target Area, as shown in Figure 1, has been substantially completed except for one section with holes DSB-26 and DSB-27 that will be drilled in the next few weeks. Overall, 25 surface (18,443m) and 19 underground (8,124m) holes totalling 26,567m have been completed to test the Santa Barbara target zone over a strike length of approximately 1,400m, across a width of 500m and to a depth of 600+m, as shown in Figure 1. The drill holes testing the Northwest Extension all intersected significant amounts of mineralization confirming that the Santa Barbara mineralization extends across the full 1,400m long target zone. Fill-in drilling from underground in the Santa Barbara adit also intersected significant mineralization and completed addition drill coverage in the eastern part of the SBBP. Assay results are pending for 22 of these mineral resource definition holes, as listed in Table 1.

An updated geological interpretation is in progress which will be used to refine the current model developed in Leapfrog mining software. The upper boundary of sulphide mineralization marked by the sulphide/oxide interface is well defined by geological logging and the magnetic susceptibility inversion model. The base of the mineralization, which is up to 600m thick, is defined by the lower limit of the high magnetic susceptibility. The northeast limit of the mineralization is defined by geology near the contact of the basement Ordovician quartz sandstones with the dacitic intrusive domes. The mineralized target zone is open along strike both to the northwest and southeast, as well as to the southwest. Data from the borehole IP inverse model is expected to aid in defining the internal geometry of the mineralization. Zones of higher sulphide content which have greater chargeability and much lower resistivity tend to be higher grade. These zones are also more magnetic because of the presence of pyrrhotite.

Exploration Drilling Porco Breccia Pipe, Gap Area and Mina 2 Targets

The focus of drilling in 2022 will shift to drill-testing the Porco Breccia Pipe (“PBP”) and the area between the PBP and Central Breccia Pipe (“CBP”) where there is a major magnetic anomaly (see press release October 21, 2021, and Figures 2 and 3), and testing the potential for a tin porphyry at depth. Figures 1 and 3 show the initial planned drilling. Holes DPC-07 and DPC-08, will initially test the Porco area targets with more follow-up drilling planned. Hole DM2-01, to be collared near the Mina 2 portal, will test for the potential tin porphyry at depth. In addition, an underground drill hole from the drill bay in the Santa Barbara adit, hole DSBU-07, will be drilled to the southwest to test the magnetic anomaly in the northern part of the CBP. Underground geological mapping and channel sampling is also in progress in the Mina 2 workings in the southern part of the property (see Figure 1 for location) with drilling also planned in this area later in the year. This area appears to be associated with a secondary caldera (Figure 1).

Eloro is currently using two laboratories, ALS Global and AHK Laboratories, both of whom have sample preparation facilities in Oruro, Bolivia and laboratories in Lima, Peru. The Company is also planning to use the ALS laboratory facility in Galway, Ireland, to achieve a faster turnaround and to help reduce the large backlog of samples with assays pending. Unfortunately, the recent wave of Covid-19 is impacting staffing at both ALS and AHK laboratories, hence there may be additional delays.

Metallurgical Drill Holes

Two diamond drill holes, METSBUG-01 and METSBUG-02 were drilled to provide larger samples of drill core for metallurgical testing. Hole MESTSBUG-01 was directed to intersect the mineralized breccia of the Santa Barbara Breccia Pipe (“SBBP”) near the centre of discovery hole DHK-15 which intersected 129.6 g Ag eq/t over 257.5m (see press release January 26, 2021). The second metallurgical hole, METSBUG-02, intersected the centre of hole DHK-18 in the mineralized envelope east of the SBBP. Hole DHK-18 returned 129.65 g Ag eq/t over 300.75m (see press release July 28, 2021). These holes have been sawn and one-quarter core sent for analysis with three-quarters core to be used for metallurgical testing.

Metallurgical Testing

A program of preliminary metallurgical testwork has been completed by the Mineral Concentration Laboratory of the National Faculty of Engineering of the Technical University of Oruro (UTO). The testwork used eight (8) composite samples assembled from early-stage resource definition drilling. These samples were selected to represent oxide and sulphide mineralization from the Huayra Kasa Mine (“HKM”) area, the SBBP and the CBP targets. Four of the samples were from HKM, three from SBBP and one from CBP. These early-stage drilling samples from these mineralized areas contained relatively low amounts of tin and therefore the conceptual testwork program was focussed on other valuable components particularly silver, zinc and lead.

The objective of this preliminary metallurgical testwork was to develop an early-stage conceptual understanding of the metallurgy. Although the program included basic mineralogy using X-ray diffraction (XRD) analysis, preliminary gravity and leach tests, and work index determinations, the main focus of the scoping level testwork program was to investigate froth flotation, without regrinding, to recover silver into separate lead and zinc concentrates. Detailed development work still needs to be done to investigate the recovery of tin, gold and other potentially valuable elements, such as indium, cadmium and bismuth.

Several open circuit flotation tests were completed using each composite sample and the results provided useful insight into the metallurgy of the Iska Iska project. The program was successful in providing a potential pathway to the successful recovery of lead, zinc and silver into saleable concentrates and will be used as a starting point for further metallurgical optimization during the next phase of testwork.

Richard Gowan, P.Eng., Principal Metallurgist for Micon International Limited, reviewed the preliminary open circuit flotation test results and considers that lead recovery of around 80% to 85% into a saleable lead concentrate could be expected once the flotation conditions were optimized. The projected zinc recovery to a final saleable zinc concentrate is around 80% to 90%. The lead concentrate would also contain considerable valuable silver and potentially payable amounts of gold, while the zinc concentrate would also contain payable amounts of silver and potentially valuable cadmium and indium. Total silver recoveries into the combined lead and silver rougher concentrates were around 73%, but with optimization Micon believes that the total flotation silver recovery can be increased up to 80%. Note that the projected recoveries based on the preliminary test data require confirmation from additional metallurgical testing hence should not be relied upon.

The next phase of testwork will be undertaken by Blue Coast Research Ltd. (“Blue Coast”) based in Parksville, BC and will optimize the flotation flowsheet to maximize lead, zinc, silver and gold into saleable concentrates and develop an appropriate flow sheet for the recovery of tin. Recovery of other more minor valuable metals including bismuth, indium and cadmium will also be considered. Blue Coast has world-class metallurgical testing, analytical services, flowsheet development, consulting and operational support. Their excellent team has been augmented with the addition of Mr. Mike Hallewell, C.Eng. a senior independent mineral processing consultant based in Cornwall, England, who has extensive specialist knowledge in the recovery of tin at mining operations and exploration projects worldwide.

Eloro, in consultation with Micon International Limited and Blue Coast, has selected four representative metallurgical samples from existing drill core in addition to the two new metallurgical holes: 1) Mineralized breccia in discovery drill hole DHK-15; 2) Mineralized dacitic envelope from hole DHK-15; 3) mineralized dacitic envelope from hole DHK-18 and 4) Sn-rich zone in hole DSB-06. Approximately 60m of core from each drill hole has been quarter cored. These samples, in addition to approximately 60m from the two metallurgical holes noted above (three-quarter core), are in the process of being shipped to Blue Coast with the testing likely to begin in the first part of February.

Bore Hole Induced Polarization Survey

The Bore Hole IP program at Iska Iska, carried out from August 2021 to December 2021, has progressed well with sixty-two (62) separate cross-hole surveys completed using many of the drill holes in the north-northeast part of the property. This program, which is being directed by Eloro’s Chief Geophysicist, Dr. Chris Hale, P.Geo., initially focused on the mineralization of the SBBP. A further nineteen (19) cross-hole surveys have also been completed to outline the PBP mineralization. In addition, forty (40) profiles have been obtained from twenty-one individual SBBP and PBP drill holes.

Two types of surveys have been carried out with two distinct objectives:

1. Pole Dipole surveys are used to profile the resistivity and chargeability of each drill hole, and

2. Cross-Hole surveys to test the continuity of mineralization between the drill holes.

In pole-dipole surveys current is injected into each hole being surveyed; one dipole length deeper than the lowest potential dipole. The current point changes throughout the survey as the entire array is lowered or raised in the drill hole.

For cross-hole surveys, current is injected at fixed points in several other drill holes around each candidate hole so that the sensitivity of the survey can be concentrated in the various volumes enclosed between different pairs of drill holes.

Low resistivity and high chargeability indicate the presence of metallic mineralization, in both survey types. Dipoles of 10, 25 and 50 m lengths were used to profile different cylinder radii around each drill hole and an additional potential was measured from the collar to depth. This provides a maximum off-hole measurement radius up to several hundred meters for the deepest stations. Profile data from the pole-dipole surveys calibrate the IP/Res response against the known mineralization in the drill core. Cross-hole data are used for inverse modelling with the UBC DCIP3D software and for interpretation of the off-hole distribution of mineralization.

The mineralization of the SBBP is being modeled using current injection from Santa Barbara and Huayra Kasa holes. PBP holes will provide a separate model of mineralization for the southern part of the property including the major target zone between the CBP and PBP.

Synchrotron Study

Synchrotron mineral cluster analysis was performed on 84 drill core samples by Dr. Lisa Van Loon of LisaCan Analytical Solutions and Dr. Neil Banerjee, P.Geo. of Western University, Department of Earth Science. These samples were selected to be representative of higher-grade areas of major and important minor metals including Ag, Sn, Zn, Pb, Au, Bi, In, Cu and Cd. This work builds on previous analytical work done on the underground channel samples from the due diligence program at Huayra Kasa (see press release June 25, 2020). The synchrotron is a type of circular particle accelerator that is an extremely powerful source of broad-spectrum electromagnetic radiation (e.g., visible light, infrared, UV, & X-rays), approximately 10 billion times brighter than the sun that provides a rapid, high-resolution analytical technique for mineral exploration.

Four (4) mineralogical domains were identified. These domains all have the same or very similar mineralogy. These mineralogical patterns are the result of the time-integrated effects of geological processes with the domains representing every event that has happened to these rocks since they were originally formed, including mineralization. Domain 2 is the largest and includes 60 samples while Domain 1 includes 17 samples, Domain 3 includes 6 samples, and Domain 4 consists of 1 sample. Within the 4 domains, Au-, Cd-, Cu-, Pb-, Sn, and Zn-dominant sub-domains are identified. The sub-domains are interpreted using the available geochemistry data to determine the predominant elements of interest within each sub-domain. These sub-domains can be used in a predictive way to better understand the spatial distribution of these elements of interest.

Domain 2 contains two Sn-dominant sub-domains. In one sub-domain Sn is associated with high Cu, Ag, Bi, and In. Cassiterite was positively identified as the Sn-bearing mineral. In the other sub-domain, Sn is associated with high Ag, but no Sn-bearing minerals were identified but this may reflect the limited number of samples (2) available in the second subdomain.

The sub-domains are interpreted to be likely related to variations in fluid composition, precipitation mechanism, or host rock interaction. The 3D distribution of the sub-domains will be evaluated in the context of lithological and structural variability within the deposit as they have important implications for geometallurgy and processing. Further work will investigate if these 3D subdomains can be used to identify blocks with different processing requirements. Additional testing is planned to further refine this pattern.

Enersoft Inc. GeologicAI Scanning Unit

Eloro has contracted Enersoft Inc. to provide a GeologicAI Scanning Unit on site in Tupiza to enable systematic scanning of diamond drill core. The GeologicAI unit has multiple scanners including XRF, Spectroscopy, 50xMicroscopic images and Laser Profilometer. The scanner, which is in a compact self-contained trailer, will provide real time processing of diamond drill core on-site. It will allow generation of mineral maps including distribution of sulphides of the polymetallic mineralization. Data from the synchrotron study will be used to help calibrate the AI to maximize its efficiency in generating these mineral maps which will be very helpful in defining metal and mineral zonation. The scanner is currently en route by boat to Bolivia and it is hoped that it will be on-site and fully operational by the end of February.

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 discovery hole on the SBBP, Eloro has released a number of significant drill results on this target, including:

• 122.66 grams 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 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 (DSB-07).

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.

Hole DCN-04 drilled at -80 degrees to the north from the northern radial platform of the CBP, intersected seventeen (17) mineralized intersections, principally Sn-Ag-bearing, over its 851.4m length. Best results include: 71.54 g Ag eq/t (32.58 g Ag/t and 0.10% Sn) over 97.10m from 134.40 to 231.5m; 101.52 g Ag eq/t (28.74 g Ag/t and 0.19% Sn) over 62.01m; 70.42 g Ag eq/t (28.74 g Ag/t and 0.16% Sn) over 22.59m; and 236.96 g Ag eq/t (92.21 g Ag/t and 0.25% Sn) over 17.45m. Hole DCS-02 was drilled southeast at -60 degrees from the south radial platform of the CBP. This hole, which was drilled to 800.5m, intersected nine (9) reportable Ag-Zn-Pb-Sn mineralized intervals. Best results include 79.53 g Ag eq/t (including 0.21% Sn) over 19.42m, 101.01 g Ag eq/t (32.76 g Ag/t, 0.76% Zn, 0.75% Pb) over 10.47 and 130.95g Ag eq/t (34.14 g Ag/t, 0.10 g Au/t, 1.35% Zn and 0.56 % Pb over 7.40m.

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 SBBP and CBP, both of which have been confirmed by drill-testing, are marked by prominent low anomalies reflecting strong alteration. The magnetic data suggests that the Central and Porco Breccia Pipes likely merge at depth. In addition, there is a prominent area of low intensity magnetics northwest of the SBBP which was reported on in this press release.

Geological mapping and satellite interpretation identified a third major breccia pipe target, Porco (South), that is approximately 600m in diameter (South) located southeast of the 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. Six (6) drill holes have been completed on Porco; assay results are pending. 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 in the current program for Iska Iska is 51,000m of which 40,000m has been completed with the aim of outlining an initial inferred NI 43-101 compliant mineral resource by Q2 2022. The target zone at the SBBP and the surrounding mineralized envelope is 1400m along strike, 500m wide and extends to a depth of 600m. This zone is open along strike to the northwest and southeast as well as to the southwest. A borehole induced polarization/resistivity (IP/Res) 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.
