AbraSilver Announces Additional High-Grade Drill Results at the JAC Zone Including 10 Metres at 520 g/t Ag & 19 Metres at 253 g/t Ag
Toronto – June 26, 2023: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) (“AbraSilver” or the “Company”) is pleased to announce the latest assay results from the ongoing Phase III diamond drilling program on the Company’s wholly-owned Diablillos property in Salta Province, Argentina (“Diablillos” or the “Project”).
Drilling is now aimed at determining the margins of the high-grade silver oxide mineralization at the JAC Zone, in preparation for a Mineral Resource estimate to be announced later this year.
Key takeaways from the latest JAC Zone drill results include:
- DDH 23-030 was drilled to test the southwest area of the JAC Zone. The hole encountered 28.3 metres grading 76.3 g/t Ag from a downhole depth of 93.7 metres.
- DDH 23-032 was drilled beyond the northwest area of JAC, towards the Alpaca target. The hole intersected multiple zones of silver mineralization in oxides, including 24.5 metres at 176.7 g/t Ag from 131.0 metres downhole.
- Follow-up drilling in this area will be conducted to test for a possible new perpendicular zone of mineralization beyond the JAC Zone, which coincides with a magnetic low.
- DDH 23-033 was drilled in the far southwest area of the JAC Zone and intersected 14.0 metres grading 193.0 g/t Ag from 125.5 metres downhole.
- DDH 23-036 was drilled to test the southwest area of the JAC Zone. The hole intersected several zones of silver mineralization, including 10.0 metres grading 520.0 g/t Ag, and a separate zone of 4.5 metres grading 496.8 g/t Ag.
- DDH 23-039 was drilled to test the southeastern area of the JAC Zone and intersected 19.0 metres grading 253.4 g/t Ag, starting from a downhole depth of 105.0 metres.
- DDH 23-044 was drilled along the southeastern area of the JAC Zone and intersected 20.0 metres grading 112.5 g/t Ag, starting from a downhole depth of only 73.0 metres.
John Miniotis, President and CEO, commented, “Today’s drill results continue to grow the mineralized footprint of the new JAC zone in several directions. In addition, these results demonstrate continuity of silver mineralization beyond the main JAC Zone, highlighting the potential for additional silver Mineral Resources in new target areas, like the Alpaca target."
Dave O’Connor, Chief Geologist, commented, “Drilling to determine the extremities of the JAC mineralized system continues to intersect several zones beyond the margins of the main orebody and these areas demonstrate significant exploration upside. In particular, hole 23-032, which intersected silver oxide mineralisation between the main JAC Zone and the Alpaca target, demonstrates potential for mineralised structures perpendicular to the JAC trend and provides further validation of mineralization being associated with magnetic lows. This Alpaca-JAC target area, as well as the Fantasma Zone, will be targeted in a new drilling campaign which will commence following completion of the JAC drilling.”
The latest assay result highlights are summarized in Table 1 below.

Drilling activity at Diablillos remains focused on the recently discovered JAC zone which is located southwest of the conceptual open pit that constrains the current Mineral Resource estimate (“MRE”) on the main Oculto deposit (M&I MRE containing 1.3 Moz gold and 109 Moz silver – Table 2).
To date, a total of 21,600 metres in 95 holes have been drilled as part of the Phase III drill program. All holes will be incorporated into an updated MRE and will be included in a Pre-Feasibility Study on the Diablillos project, which the Company expects to complete in the second half of 2023.
Moreover, additional exploration targets have been identified to the southwest of the Oculto MRE based on the recently completed detailed ground magnetic survey. Some of these targets, including the Fantasma and Alpaca targets, will be drilled following the completion of the current Phase III drill program.

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 120,000 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 2:

Notes: Effective October 31, 2022. Mineral Resources are not Mineral Reserves and have not demonstrated economic viability. The Mineral Resource estimate is N.I. 43-101 compliant and was prepared by Luis Rodrigo Peralta, B.Sc., FAusIMM CP(Geo), Independent Consultant. The mineralization estimated in the Mineral Resource is sub-horizontal with sub-vertical feeders and a reasonable prospect for eventual economic extraction by open pit methods.

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.
David O’Connor P.Geo., Chief Geologist for AbraSilver, is the Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects, and he has reviewed and approved the scientific and technical information in this news release.
AbraSilver is an advanced-stage exploration company focused on rapidly advancing its 100%-owned Diablillos silver-gold project in the mining-friendly Salta province of Argentina.
