Eloro Resources Intersects 66.90g Ag/t, 0.63% Zn, 0.42% Pb and 0.11% Sn (111.14g Ag eq/t) over 289.13m in First Hole of Definition Drilling at the Iska Iska Project, Potosi Department, Southwestern Bolivia

Intersection in hole DSB-68 above also includes higher grade intervals of: 126.10g Ag/t, 0.55% Zn, 0.60% Pb and 0.09% Sn (160.72g Ag eq/t) over 122.03m, 47.61g Ag/t, 0.22% Zn, 0.40% Pb and 0.45% Sn (146.06g Ag eq/t) over 16.51m, and 25.52g Ag/t, 2.19% Zn, 0.65% Pb and 0.10% Sn (129.60g Ag eq/t) over 7.46m The high grade mineralization is associated with a prominent intrusion breccia body that is widening at depth over a vertical interval of over 500m and likely extends much further to the south. This breccia body is likely a major feeder for mineralization. Geophysical data indicates that there is a prominent northwest trending structural corridor 500m wide that extends from the Santa Barbara area southeastwards for at least 2km. Within the Santa Barbara High Grade Corridor, a strong spatial correlation is evident between the high-grade intersections in the intrusion breccia and areas of higher chargeability. This hole is the first of a strategic infill program in the potential starter pit area at Santa Barbara to better define the vertical and lateral extent of high-grade Ag mineralization; fill-in gaps that are presently categorized as low-grade or waste in the mineral resource model but are very likely mineralized; expand the higher-grade Sn mineralization to the west; and complete two large size PQ holes for further metallurgical testing (see Eloro press release of September 4, 2024).

Eloro Announces Restart of Definition Diamond Drilling on the Iska Iska Silver-Tin Polymetallic Project, Potosi Department, Southwestern Bolivia

Updated modelling of the potential starter pit area at Santa Barbara indicates that areas with higher-grade mineralization typically have much better drilling density, whereas holes outside the core area are too widely spaced to give an accurate grade estimate. This increased drilling density is particularly important for defining the extent of the high-grade Ag-bearing and Sn-bearing structures, and for categorizing the mineral resources from inferred to indicated, which have a major influence on overall grade and resources that will contribute to the preliminary economic assessment (“PEA”). An initial program of 5,700m of diamond drilling in 13 holes in the Santa Barbara starter pit area is planned to better define the vertical and lateral extent of high-grade Ag mineralization; fill-in gaps that are presently categorized as low-grade or waste in the resource model but are very likely mineralized; expand the higher-grade Sn mineralization to the west; and complete an additional 1,400m in two large size PQ holes for further metallurgical testing. Drill pads are expected to be completed by mid-September for start up of this initial diamond drilling program. The Santa Barbara Adit and area will be of particular interest and focus, where previous systematic continuous channel sampling along the adit returned average grades of 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. Once this initial 7,100m drilling program is completed, an additional 7,000m drilling program is planned in the polymetallic Ag-Zn-Pb and Sn-Ag domains to produce an independent updated mineral resource estimate (“MRE”) which will be reported and incorporated into the PEA. The Eloro team continue to look for opportunities to process tin zones for recovery of cassiterite either after cessation of the aforementioned Ag-Zn-Pb project by adding a tin plant onto the existing flotation plant infrastructure already installed or construction of a stand-alone tin plant. A silver rich bi-product is envisaged from processing the tin-silver domain that would be commercialized separately. The tin–silver sulphide domain will be metallurgically tested so it can be included in the PEA study. A conceptual scoping study has been initiated that will identify the potential for developing an underground ramp into the core of the Santa Barbara zone, with the following objectives: Extract systematic bulk and channel samples to confirm grade and continuity of mineralization especially for Ag and Sn Generate samples for external laboratory bulk metallurgical test work Potentially leading to a small pre-concentration plant to generate additional metallurgical data on this important stage in the process and permit pre-concentrated “ore” that could be treated at Empresa Minera Villegas SRL’s lead-zinc-silver differential flotation plant located 15 km from Iska Iska for the production of silver-rich lead and zinc concentrates. This would potentially provide a source of short-term income to help support the capital and operating costs of this initiative. It would also demonstrate the technical viability of the pre-concentration plant unit processes in readiness for the 35,000 tonnes per day bulk tonnage open pit mine model envisioned for the PEA. Detailed geological and engineering work to further assess the ground-water quality, contamination risks, predicting geologic hazards, characterizing mineral resources and their extraction costs, producing geotechnical information, waste repository siting and general education. Provide access for targeted underground diamond drilling to further upgrade the mineral resource

Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE: P2QM) (“Eloro: or the “Company”) is pleased to provide an update on Eloro’s Iska Iska silver-tin polymetallic project in Potosi Department, southern Bolivia. read more

Eloro Resources’ drill hole DHK-27 intersects 202.43g Ag eq/t (69.80g Ag/t, 1.21% Zn, 0.49% Pb, and 0.12%Sn) over 325.48m including a higher-grade portion of 395.98 g Ag eq/t (182.02g Ag/t, 1.73% Zn, 0.97% Pb, 0.18% Cu and 0.19%Sn) over 109.60m in the High-Grade Zone, Santa Barbara Deposit at the Iska Iska Silver-Tin Polymetallic Project, Potosi Department, Bolivia

The silver grades in DHK-27 are the highest and most extensive yet intersected in the Santa Barbara deposit. 50% of this 860m long hole, drilled from Huayra Kasa due west at -45 degrees, returned reportable intersections averaging 172.09 g Ag eq/t. Holes DHK-26, DHK-28, DHK-29, DHK-30 and DSB-42, which returned multiple intersections, are additional holes collared in the Huayra Kasa area that tested the eastern margin of the High-Grade Zone at Santa Barbara. Highlights include: 222.51g Ag eq/t (28.44g Ag/t, 3.11% Zn and 0.26% Pb) over 53.90m and 99.76 g Ag eq/t (32.59g Ag/t, 0.11 g Au/t and 0.54% Zn) over 82.38m (DHK-26). 79.22g Ag eq/t (26.62g Ag/t, 0.35% Zn and 0.35% Pb) over 141.56m including 162.77g Ag eq/t (67.00g Ag/t, 0.55% Zn and 1.30% Pb) over 23.85m (DHK-28). 176.28g Ag eq/t (19.10g Ag/t, 2.29% Zn and 0.27% Pb) over 21.30m and 82.48g Ag eq/t (5.07g Ag/t, 0.21 g Au/t, 0.78% Zn and 0.18% Pb) over 69.18m (DHK-29). 130.69g Ag eq/t (7.19g Ag/t, 1.83% Zn and 0.48% Pb) over 42.17m and 129.98g Ag eq/t (19.71g Ag/t, 1.50% Zn and 0.57% Pb) over 72.31m including a higher-grade portion of 208.42g Ag eq/t (33.10g Ag/t, 2.37% Zn and 1.00% Pb) over 34.64m (DSB-42). Channel sampling of the Mina1 and Mina2 underground workings in the southern part of the property approximately 2km south-southeast of the Santa Barbara adit, returned significant values in vein breccias as follows: 153.94g Ag eq/t (55.03g Ag/t, 0.11 g Au/t, 0.7% Zn, 0.16% Pb and 0.08 % Sn) over 145.95m of the northwest trending drift including a higher-grade portion of 285.16g Ag eq/t (120.18g Ag/t, 0.25 g Au/t 1.23% Zn, 0.30% Pb and 0.13% Sn) over 56.34m in Mina 1. 382.79g Ag eq/t (15.67g Ag/t, 1.70 g Au/t, 2.20% Zn and 0.75% Pb) over 68.53m in an east-west trending crosscut in Mina 2. A second shorter crosscut on a secondary subparallel structure approximately 20m to the south returned 475.78g Ag eq/t (69.31g Ag/t, 0.26 g Au/t, 5.62% Zn and 1.92% Pb) over 26.67m in Mina 2. Drilling across the valley of the Iska Iska Caldera indicates that this area is underlain by a coarse-grained porphyritic dacitic intrusion that is well mineralized with Ag, Zn and Pb and is the likely source of the extensive epithermal mineralization in the Santa Barbara and Central Breccia areas. The porphyry, now named the Iska Iska Porphyry, is approximately 800m by 600m and is notable for the absence of tin mineralization despite the abundance of tin in the nearby area. The tin at Iska Iska is likely the product of an earlier higher temperature and deeper tin porphyry, which has been overprinted by the later higher-level porphyry-epithermal Ag-Zn-Pb mineralization related to the Iska Iska Porphyry. The definition drilling has more than doubled the volume of the High-Grade Zone defined by the >90 g Ag eq/t grade shell model to approximately 1,000m along strike, 800m wide and extending to a depth of 1,100m. This zone is open to the south, west and northwest as well as at depth. Eloro is working closely with Micon International to provide all data necessary for estimation of the inaugural mineral resource estimate targeted for the end of Q1 2023. Magnetic inverse modelling and limited deep drilling suggest that the major tin porphyry is likely below the Iska Iska Porphyry and to the south and southwest in the Porco and Mina Casiterita areas. The tin porphyry will be a major focus of exploration in 2023.
