ELO Eloro Resources Ltd

Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro”, or the “Company”) is pleased to announce the first assay results from five (5) of the drill holes in its eleven (11) hole 5,267.7m definition drill program on the Iska Iska silver-tin polymetallic project in the Potosi Department of southwestern Bolivia.

Tom Larsen, CEO of Eloro commented: “These latest drill hole results are very encouraging. They demonstrate substantive higher-grade intervals, especially for silver, in the potential starter pit mineral resource area that may now be potentially upgraded and expanded.”

Larsen continued, “Significant tin is present in several holes with grades up to 0.5 percent, highlighting the chances to expand and increase the grade of the tin resource which is a high priority exploration target in 2024. As we expected, the higher-grade silver and tin intercepts from this definition drill program are demonstrating selective higher-grade metal zonation within the starter pit area and the Tin (Sn-Ag-Pb) Domain. We expect to release results from the six (6) remaining definition drill holes in the first part of January 2024, concluding our first phase infill definition drilling program aimed to enhance grade and expand tonnage in the Santa Barbara starter pit area.”

The definition diamond drill program focussed on upgrading and expanding the higher-grade Polymetallic (Ag-Zn-Pb) Domain Type inferred mineral resource, which as previously reported (see Eloro press release dated October 17, 2023) contains an inferred mineral resource of 132 million tonnes at 24.3 g Ag/t, 1.11% Zn and 0.50% Pb (72.06 g Ag eq/t) at an NSR cutoff of $US25/t. The net NSR value of this higher-grade resource is US$34.40/t which is 3.75 times the estimated operating cost of US$9.20/t.   Several of these holes also tested the adjacent Tin (Sn-Ag-Pb) Domain where high values of silver (Ag) have previously also been obtained in addition to tin.

Dr. Bill Pearson, P.Geo. Executive Vice President, Exploration said: “The bulk of mineralization at Iska Iska, especially the high-grade Ag zones, occur within veins, vein breccias and veinlets that overall have a general west-northwest trend (300o). Channel sampling of a typical high-grade structure in the Santa Barbara adit (see Eloro press release dated April 21, 2021) returned 165 g Ag/t, 3.46% Pb and 0.46% Sn (310.25g Ag eq/t) over 166m which included a very high-grade section of 446 g Ag/t, 9.03% Pb and 1.16% Sn (817.38g Ag eq/t) over 56.19m. This gives an excellent indication of the potential strike length of these high-grade Ag structures, as well as the potential for bonanza-type grades in them. Closer spaced drilling as expected, provides a better definition of these important mineralized structures, especially those with higher grade silver, which has the potential to increase the overall resource grade as well as expand resource tonnage.”

Pearson continued: “Work is continuing on the “ore-sorting” tests with metallurgical work on the concentrate samples produced at TOMRA in Germany being completed at Wardell Armstrong in Cornwall. In addition, our geophysicists are processing new IP data which will provide important information on potential extensions of the remarkable Iska Iska mineralizing system.”

Table 1 below lists significant results for the five drill holes reported. Figure 1 shows locations of all the definition drill holes completed with the holes with results released highlighted. Silver equivalent (g Ag/t) has been calculated using 3-year average metal prices and preliminary metallurgical recoveries (see note below Table 1 for more information).

DEFINITION DRILL PROGRAM

The definition drill program has been designed to fill-in major gaps in the block model as well as upgrade and expand the higher-grade zone both along and across strike in the general area of the potential starter pit. As noted by Micon International Limited, authors of the National Instrument 43-101 (“NI 43-101”) Technical Report detailing the initial Iska Iska mineral resource estimate (“MRE”)(see Eloro press release dated October 17, 2023), the highest-grade areas are also the best drilled. As drill density in the deposit is improved, it is expected that grade will increase due to better sample density. Initial results reported herein confirm that this is likely the case.

Table 2 lists the coordinates of the Definition Drill Holes with assay results reported in this release and holes for which assay results are pending. Figure 1 shows the locations of the definition drill holes with holes reported in this release highlighted in yellow.

Qualified Person (“QP”)

The inaugural MRE for Iska Iska outlined in the NI 43-101 Technical Report (see Eloro press release dated October 17, 2023) has been prepared by Micon International Limited. Independent QPs for the Technical Report are Charley Murahwi, P.Geo., FAusIMM, Richard Gowans, P.Eng., Ing. Alan J. San Martin, MAusIMM (CP) and Abdul Aziz, Drame, P.Eng., all of whom are independent QP’s as defined by NI 43-101. Mr. Murahwi completed site visits in January 2020 and November 2022.  

Dr. Bill Pearson, P.Geo., Vice President Exploration, Eloro and a QP as defined by NI 43-101 has reviewed and approved the technical content of this news release.   Dr. Pearson who has more than 48 years of worldwide mining exploration, development and production experience, including extensive work in South America, manages the overall technical program, working closely with 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 NI 43-101, who has supervised all field work carried out at Iska Iska.

Eloro utilized both ALS and AHK for drill core analyses, both of whom are major international accredited laboratories. Drill samples sent to ALS were 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. 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 were prepared in a preparation facility installed and managed by AHK in Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Check samples between ALS and AHK are regularly done as a QA/QC check. AHK is followed the same analytical protocols used as with ALS and with the same QA/QC protocols.

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 100% 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 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 164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu over 166m including 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 DHK-15 which returned 29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu and 0.056%Sn over 257.5m, Eloro has released a number of significant drill results in the SBBP and the surrounding mineralized envelope which along with geophysical data has defined an extensive target zone. On October 17, 2023, Eloro filed the NI 43-101 Technical Report outlining the initial inferred MRE for Iska Iska, prepared by Micon International Limited. The MRE was reported in two domains, the Polymetallic (Ag-Zn-Pb) Domain which is primarily in the east and south of the Santa Barbara deposit and the Tin (Sn-Ag-Pb) Domain which is primarily in the west and north. The Polymetallic Domain is estimated to contain 560Mt at 13.8 g Ag/t, 0.73% Zn & 0.28% Pb at an NSR cutoff of US$9.20 for potential open pit and an NSR cutoff of US$34.40 for potential underground. The majority of the mineral resource is contained in the constraining pit which has a stripping ratio of 1:1.

The Polymetallic Domain contains a higher-grade mineral resource at a NSR cutoff of $US25/t of 132 million tonnes at 1.11% Zn, 0.50% Pb and 24.3 g Ag/t which has a net NSR value of US$34.40/t which is 3.75 the estimated operating cost of US$9.20/t. The Tin Domain which is adjacent the Polymetallic Domain and does not overlap, is estimated to contain a mineral resource of 110Mt at 0.12% Sn, 14.2 g Ag/t and 0.14% Pb but is very under drilled.

The Company has completed a 5,267.7m definition drill program to expand the higher-grade mineral resource in the Polymetallic Domain and has commenced a preliminary economic evaluation (PEA) led by Lycopodium.
