AbraSilver Discovers New Near-Surface, High-Grade Silver Zone at Diablillos; Intersects 357 g/t AgEq (5.1 g/t AuEq) Over 87 Metres

Toronto – August 03, 2022: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is very pleased to announce the discovery of a new near-surface, high-grade silver zone, located over 500 metres southwest of the Oculto Mineral Resource, on the Company's wholly-owned Diablillos property in Salta Province, Argentina (“Diablillos” or the “Project”).

Diamond drill hole DDH 22-019 contains the discovery hole for the promising new zone, called the ‘Southwest zone’.  Key takeaways include:

  • Hole DDH 22-019 intersected a high-grade interval of 87 metres at 357 g/t AgEq (5.1 g/t AuEq - comprised of 346 g/t Ag and 0.15 g/t Au) in oxides starting at a down-hole depth of only 89 metres. The hole included a 22 metre interval grading 1,033 g/t AgEq (14.8 g/t AuEq – comprised of 1,015 g/t Ag & 0.27 g/t Au);
  • The reconnaissance hole was drilled to test a magnetic anomaly extending beneath colluvial cover southwest of Oculto. The newly discovered Southwest zone is located over 500 metres beyond the limit of the current Mineral Resource estimate at Oculto.

John Miniotis, President and CEO, commented, “We’re thrilled that we continue to discover new high-grade, near-surface silver mineralization at our world-class Diablillos project. It is extremely promising for the first hole in a new, untested target to return such strong, high-grade results.  Importantly, the high-grade mineralization is thick, near surface, and demonstrates excellent potential for continuity, thereby ranking it as our highest-priority exploration target for our ongoing Phase III drill program.  We’re eagerly looking forward to announcing more results from this new zone over the coming weeks and months ahead."

The latest assay result highlights are summarized in Table 1 and Table 2 below.

Dave O’Connor, Chief Geologist, commented, “Hole DDH 22-019 is a spectacular exploration success. The hole was drilled to test a linear magnetic anomaly interpreted as being a potential feeder zone hosting a mineralised breccia. This has turned out to be the case and is supported by the high-grade copper sulphide mineralisation at the base of the oxide silver zone. The magnetic anomaly extends for over one kilometre under colluvial cover southwest of Oculto.  Looking forward, our immediate priority is to now systematically drill the Southwest zone in order to determine the scale of this new system. The colluvial cover is about 50-60 metres thick, and the oxide silver mineralisation appears to commence immediately beneath it, presenting an ideal open pit mining situation.”

Discussion of Drill Hole Results

Hole DDH 22-019 was a step-out reconnaissance hole drilled to test a magnetic anomaly extending beneath colluvial cover southwest from the currently defined mineralization at Oculto. The hole is located over 500 metres beyond the limit of the current Oculto Mineral Resource estimate and discovered a new shallow zone of high-grade silver mineralization including visible silver. The hole, which was inclined 60 degrees to the north, intersected 87 metres grading 346 g/t silver and 0.15 g/t gold in oxide mineralisation from 89.0 to 176.0 metres down-hole, including 22.0 metres grading 1,015 g/t silver and 0.27 g/t gold, and including 7.0 meters with 2,001 g/t silver and 0.42 g/t gold. The hole was stopped in sulphide mineralization with 1.0 metre at 31.3g/t Ag and 2.63% Cu from 177.0 to 178.0 metres.

A follow-up hole, DDH 22-044, has recently been drilled 50 metres east-northeast of hole DDH 22-019 and, based on visual interpretation, appears to have intersected very similar altered breccia for which analytical results are currently pending. Five additional drill platforms have been prepared in the Southwest zone which will enable immediate systematic follow-up drilling.

The new Southwest zone adds a brand-new dimension to the Diablillos project and opens up considerable blue sky potential. The prominent linear magnetic anomaly tested by hole DDH 22-019 follows the same east-northeast direction as the conduits that host the mineralised hydrothermal breccias at Oculto. The structural zone interpreted to be the cause of the magnetic anomaly extends for at least one kilometre beyond the conceptual Oculto open pit margin. The high-grade silver encountered in hole DDH 22-019 demonstrates potential for a major mineralised zone extending well to the southwest of Oculto.

Hole DDH 22-017 was drilled in the northeast zone to test a parallel structure north of the Main Breccia. The hole successfully intersected several shallow intercepts of oxide mineralisation, with 31 metres at 48.4g/t silver and 0.87g/t gold starting from 99.0 metres downhole.

Holes DDH 22-018 and DDH 22-020 were drilled to explore for shallow mineralisation in the southwest part of the proposed Oculto pit, north of the Main Breccia. Both holes intersected moderate grade, shallow mineralisation.

Diablillos Drill Program Update

The Company’s Phase II, 20,000-metre drill program has been successfully completed, having delivered numerous positive results throughout the past year.   At this time, assay results for the final 12 holes from this campaign remain pending and are expected to be received over the next several weeks.  Once all assay results from the Phase II program are received, the Company will prepare and publish an updated Mineral Resource estimate, which is anticipated to be completed in September 2022.  The best results to date from the Phase II program are summarized in Table 3, below.

 About Diablillos

The 80 km2 Diablillos property is located in the Argentine Puna region - the southern extension of the Altiplano of southern Peru, Bolivia, and northern Chile - and was acquired from SSR Mining Inc. by the Company in 2016.  There are several known mineral zones on the Diablillos property, with the Oculto zone being the most advanced with over 90,000 metres drilled to date.  Oculto is a high-sulphidation epithermal silver-gold deposit derived from remnant hot springs activity following Tertiarty-age local magmatic and volcanic activity. Comparatively nearby examples of high sulphidation epithermal deposits include: Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo del Sol (Argentina).

The most recent Mineral Resource Estimate for the Oculto Deposit is shown in Table 4 below:

QA/QC and Core Sampling Protocols

AbraSilver applies industry standard exploration methodologies and techniques, and all drill core samples are collected under the supervision of the Company’s geologists in accordance with industry practices. Drill core is transported from the drill platform to the logging facility where drill data is compared and verified with the core in the trays. Thereafter, it is logged, photographed, and split by diamond saw prior to being sampled. Samples are then bagged, and quality control materials are inserted at regular intervals; these include blanks and certified reference materials as well as duplicate core samples which are collected in order to measure sample representivity. Groups of samples are then placed in large bags which are sealed with numbered tags in order to maintain a chain-of-custody during the transport of the samples from the project site to the laboratory.

All samples are received by the SGS offices in Salta who then dispatch the samples to the SGS preparation facility in San Juan. From there, the prepared samples are sent to the SGS laboratory in Lima, Peru where they are analyzed. All samples are analyzed using a multi-element technique consisting of a four acid digestion followed by ICP/AES detection, and gold is analyzed by 50g Fire Assay with an AAS finish. Silver results greater than 100g/t are reanalyzed using four acid digestion with an ore grade AAS finish.
