AbraSilver Continues to Extend Mineralisation Beyond Open Pit Margin Intersecting 57m at 3.01 g/t Gold-Equivalent in Oxides at Diablillos
High-Grade Intercept Includes 17m at 6.16 g/t Gold-Equivalent (431 g/t Silver-Equivalent)
Toronto - March 10, 2022: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is pleased to announce the latest diamond drill hole assays from the ongoing Phase II drill program on the Company’s wholly-owned Diablillos property in Salta Province, Argentina. The latest step-out drill holes continue to confirm the existence of broad intervals of silver and gold mineralization in both directions along strike beyond the current conceptual Preliminary Economic Assessment (“PEA”) open pit margin.
John Miniotis, President and CEO, commented, “Today’s drill results highlight the significant opportunity for AbraSilver to increase Mineral Resources beyond the levels included in the estimate announced in September 2021. The ongoing Phase II drill program results continue to confirm that the high-grade oxide mineralization extends along strike beyond the conceptual PEA open pit boundary, both towards the southwest and northeast. Additionally, we also continue to extend the mineralization at depth where we are now planning a systematic drilling program to test the extent of the deeper sulphide mineralisation later on this year.”
The latest assay result highlights are summarized in Table 1 below.

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.
1 AgEq & AuEq calculations for reported drill results are based on USD $1,750/oz Au, $25.00/oz Ag and $3.00/lb Cu. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices.

Discussion of Drill Hole Results
Hole DDH 21-067 was drilled to test the north-eastern extension of the Main Breccia, while hole DDH 21-068 was drilled to test the south-western extension of the Main Breccia. Both holes were drilled on the margin of the conceptual PEA open pit to test the expansion potential of the pit to incorporate more mineral resources.
Hole DDH 21-067 intersected several high-grade mineralised zones, including 56.0 meters at 83.5 g/t silver from 137 to 193 meters, and 66.0 meters at 1.90 g/t gold and 57.0 g/t silver from 242 to 308 meters, including 9.0 meters at 4.02 g/t silver and 94.2 g/t silver.
Hole DDH 21-068 intersected 57.0 meters at 1.47 g/t gold and 108.0 g/t silver from 89 to 146 meters, including 17.0 meters at 4.65 g/t gold and 105.6 g/t silver.
These two holes show high-grade mineralisation at the margins of the conceptual open pit and demonstrate the potential for expansions of the pit both towards the southwest and northeast.

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 meters 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 Mineral Resource for the Oculto Deposit is shown in Table 2 below:

Effective September 8, 2021. The Mineral Resource estimate and supporting Technical Report are N.I. 43-101 compliant. Full details of the Mineral Resources are available in a Company news release dated September 15, 2021.

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 a well-funded silver-gold focused advanced-stage exploration company. The Company is rapidly advancing its 100%-owned Diablillos silver-gold project in the mining-friendly Salta province of Argentina, which has a current Measured and Indicated Mineral Resource of over 90 million ounces of silver and 1.0 million ounces of gold. The updated PEA study completed in November 2021 demonstrates that Diablillos has the potential to be a highly-economic project. The Company is led by an experienced management team and has long-term supportive shareholders including Mr. Eric Sprott and SSR Mining.
