Toronto, ON – TheNewswire – January 10, 2023 – AbraSilver Resource Corp. (TSXV:ABRA) (OTC:ABBRF) (“AbraSilver” or the “Company”) is very pleased to announce the discovery of a new high-grade feeder structure at the recently discovered Southwest zone (JAC target), located several hundred metres beyond the current Mineral Resource estimate on the main Oculto deposit at the Company’s Diablillos project (“Diablillos” or the “Project”).
Hole DDH 22-067 encountered the highest-grade intercept to date, on a silver-equivalent basis, at the JAC target, with 871 g/t AgEq over 27m in sulphide mineralization. That interval is located immediately beneath a further high-grade oxide intercept grading 522 g/t AgEq over 36m.
Highlights and detailed results are shown below along with accompanying figures:
-
Hole DDH 22-067 intersected a new high-grade feeder structure at the JAC target and encountered two separate high-grade zones:
-
The other four reported holes tested the margins of the high-grade silver mineralization at the JAC target, with hole DDH 22-065 encountering 35m at 82 g/t Ag from a downhole depth of 83.0m

Note: All results in this news release are rounded. Assays are uncut and undiluted. Widths are drilled widths, not true widths. True widths are estimated to be approximately 80% of the interval widths.
1AgEq based on 81.9(Ag):1(Au) calculated using long-term prices of US$25.00/oz Ag and US$1,750/oz Au, and 73.5% process recovery for Ag, and 86.0% process recovery for Au as demonstrated in the Company’s Preliminary Economic Assessment in respect of Diablillos dated January 13, 2022, using formula: AgEq g/t = Ag g/t + Au g/t x (Gold Price/Silver Price) x (Gold Recovery/Silver Recovery). No value is ascribed to copper grades in the AgEq calculations.

John Miniotis, President and CEO, commented, “The discovery of a high-grade feeder structure in the JAC target represents another significant achievement for our ongoing Phase III exploration program. The high silver grades over substantial widths reported in hole 22-067 highlight the significant blue-sky potential of our recently discovered JAC target. We remain convinced, now more than ever, that AbraSilver remains exceptionally well-positioned to unlock significant shareholder value in 2023 with several near-term catalysts on the horizon, including: additional drill results; a maiden Mineral Resource estimate on the JAC target; and a Pre-Feasibility Study on the entire Diablillos project, all expected to be announced in H1/2023.”
Dave O’Connor, Chief Geologist, commented, “The exceptional grades encountered in hole 22-067 showcases the continuity of high-grade mineralization within our exciting JAC target. Intersecting a high-grade feeder is of primary importance in building confidence in our geologic model and enhancing our understanding of this new deposit. Our immediate exploration priority is to continue drill testing this high-grade feeder structure while continuing to delineate other high-grade targets which were recently identified by our latest ground magnetic survey.”

Exploration Update
Systematic grid drilling, at 25 and 50 metre spacing, of the JAC target continues to progress rapidly. To date, assay results have been announced for a total of 19 holes in the JAC target, with all holes returning silver mineralization at reasonably shallow depths. The limits of the JAC mineralised zone have yet to be found and drilling is continuing to determine the length and width of the JAC target. A total of 43 holes have now been drilled in this new zone, with assays pending for 24 holes.
The JAC target was discovered by drilling a linear magnetic anomaly interpreted, correctly, as resulting from the introduction of mineralizing hydrothermal fluids. A new detailed ground magnetic survey was recently completed by geophysical consultants, Quantec Geoscience Ltd. The figure below shows the reduced to pole magnetic character of the Oculto area with numerous low magnetic signature zones in the west and southwest portion of the plan marked in blue, including the JAC Zone which is the current drill target. The low magnetic zones follow a conjugate set of linears, with the JAC Zone on a marked east-northeast trending structure and other potential targets on west-northwest structures, including the Fantasma target. In addition to the completion of grid drilling at the JAC target to outline an initial Mineral Resource estimate, reconnaissance drilling is planned on other target areas to the west of Oculto, including Fantasma, Alpaca and other targets as shown in Figures 1 and 3.

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 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. For additional information please see Technical Report on the Diablillos Project, Salta Province, Argentina, dated November 28, 2022, completed by Mining Plus, and available on www.SEDAR.com.
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.
