AbraSilver Drilling Continues to Intersect High-Grade Mineralization at the JAC Zone;

Latest Results Include 17 Metres at 829 g/t Ag & 79 Metres at 238 g/t Ag

Toronto – May 25, 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”). The Company is also pleased to announce that the Phase III program is

being increased as mineralization at the JAC zone remains open.

Drilling at the JAC zone continues to consistently intersect high-grade silver oxide mineralization, with

associated gold in some areas, at shallow depths, as well as underlying copper and silver mineralization

in sulphides.

Notably, drill hole DDH 23-029 encountered silver mineralization in oxides to the west of the main JAC

mineralized zone, which was drilled to test an extension of the magnetic anomaly associated with the

mineralization at JAC. This mineralization is hosted in granitic basement rocks under the andesite

volcanics and, consequently, opens up potential for further mineralized zones. Additionally, the JAC

zone continues to remain open along strike towards the southwest and in other directions.

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

widths. True widths are estimated to be approximately 80% of the interval widths for oxides.

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).

John Miniotis, President and CEO, commented, “We continue to intercept excellent widths and grades of

silver at JAC in practically every single drill hole. Additionally, we continue to see significant potential

for new discoveries beyond the main JAC mineralized zone, as highlighted in hole DDH 23-029. Our drill

results continue to confirm our belief that the new JAC zone is a major mineralized system, with significant

exploration upside remaining to be discovered. For that reason, we are again increasing the amount of

drilling being done as part of the Phase III program.”

Dave O’Connor, Chief Geologist, commented, “In addition to consistently encountering high-grade silver

mineralization with associated gold at JAC, we are also intersecting underlying high-grade copper

mineralization with associated silver/gold in sulphides immediately beneath the oxides. It is now evident

that the high-grade sulphide mineralization in zones beneath the base of oxidation is continuous for at

least 2 km along the length of the Oculto-JAC system, representing an additional attractive exploration

target, beyond the oxidized mineralization at JAC.”

Key takeaways from the latest JAC zone drill results include:

 DDH 23-024 was drilled to test continuity of the JAC Zone for resource estimation. The hole

intersected multiple zones of silver mineralization in oxides, with 17.0 metres grading 828.9 g/t

Ag from a downhole depth of 144.0 metres, including 5.0 metres grading 2,215.4 g/t Ag.

 DDH 23-025 was drilled to test continuity of the JAC Zone for resource estimation. The hole

intersected significant silver and gold mineralization in oxides, including 79 metres at 237.6 g/t

Ag and 0.15 g/t Au from 100.0 metres downhole.

o Immediately beneath this high-grade oxide intercept, the hole encountered 30.5 metres

grading 3.28% Cu and 96.6 g/t Ag in sulphide mineralization. This is the best copper

intercept drilled at JAC to date on a grade-thickness basis, demonstrating the potential

of high-grade feeder structures at JAC to host substantial sulphide mineralisation.

 DDH 23-026 was drilled to test the north-eastern extremity of the JAC Zone near the Oculto

conceptual open pit, and encountered silver and gold mineralization in oxides, intersecting 19.0

metres grading 107.3 g/t Ag and 0.69 g/t Au from 131.0 metres downhole.

 DDH 23-027 was drilled to test the northern margin of the JAC Zone and intersected 59 metres

grading 129.6 g/t Ag, including 4 metres grading 812.2 g/t Ag, starting from a downhole depth

of only 56.0 metres.

 DDH 23-028 was drilled to test continuity of the JAC Zone for resource estimation. The hole

encountered 24.5 metres grading 189.8 g/t Ag in the oxide/sulphide transition zone, including

3.0 metres grading 1,174.9 g/t Ag and 0.79% Cu in sulphides, starting from a downhole depth

of 156.5 metres.

 DDH 23-029, was drilled beyond the JAC drill target area to explore for a possible new

perpendicular zone of mineralization. The hole showed continuity of silver dominant

mineralisation beyond the current southwestern margin of the JAC deposit and intersected 31.4

metres grading 174.4 g/t Ag in oxides starting from a downhole depth of 126.0 metres.

o The hole is located on a zone of low magnetic intensity heading NW from the main JAC

trend towards the Alpaca target where historical drilling intersected silver mineralisation.

Additional drilling in this area will now be conducted.

Exploration Update

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).

Two rigs have essentially completed drilling the planned 22,000-metre Phase III program with results

demonstrating mineralization at the JAC zone over an area at least 800 metres by approximately 200

metres. As the JAC zone remains open in several directions, the Company now plans to drill at least an

additional 15 holes as part of the Phase III program in order to define the limits of the high-grade silver

mineralization in oxides. All Phase III drill 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 systematic drilling of the JAC zone.

About Diablillos

The 80 km 2 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).

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.
