AbraSilver Reports Multiple High-Grade Silver Intercepts Extending JAC Mineralization at Diablillos; Including 63.5 Metres Grading 190 g/t Ag

(TheNewswire)

High-Grade Results Support Resource Expansion Ahead ofUpcoming Mineral Resource Estimate

Toronto – April 02, 2025 – TheNewswire- AbraSilver ResourceCorp. (TSX: ABRA; OTCQX: ABBRF) (“AbraSilver” or the “Company”) is pleased to announce new assay results from the recentlycompleted Phase IV drill program on its wholly-owned Diablillosproject in Argentina (the “Project”).

The latest results from step-out drilling at the JACExtension and Oculto Northeast zones, returned multiple high-gradesilver intercepts beyond the current conceptual open pit margins. These results are expected to contribute to a meaningful increase inthe upcoming Mineral Resource estimate, scheduled for release inmid-2025, which will form the basis for the Definitive FeasibilityStudy that is currently underway.

Key highlights include:

JAC Extension:

• Hole DDH 24-077: 41.0 metres(“m”) at 113 g/t Ag , starting at 88 mdown-hole depth, including 8.5 m at 301 g/tAg

• Hole DDH 24-078: 36.0 m at 148g/t Ag, from 137 m depth, including 15.0 m at 182 g/t Ag.

• Hole DDH 24-079: 47.0 m at 169g/t Ag , from 111 m depth, including 4.0 m at 674 g/t Ag

• Hole DDH 24-080: 67.2 m at 77 g/tAg , from 68 m depth, including 12.0 m at 136 g/t Ag

• Hole DDH 24-082: 54.0 m at 125g/t Ag , from 51 m depth, including 8.0 m at 228 g/t Ag

• Hole DDH 24-084: 63.5 m at 190g/t Ag , from 80 m depth, including 9.0 m at 341 g/t Ag

• Hole DDH 24-088: 70.0 m at 147g/t Ag , from 61 m depth, including 9.0 m at 331 g/t Ag

• Hole DDH 24-090: 40.5 m at 86 g/tAg , from 89 m depth, including 7.0 m at 218 g/t Ag

Oculto Northeast:

• Hole DDH 24-074: Drilled 100 m beyond the margin of theOculto Mineral Resource, returned 10.0 m grading1.49 g/t Au and 56 g/t Ag in oxides, from adown-hole depth of 206 m .

John Miniotis, President and CEO, commented, “Onceagain, our latest drill results highlight the significant growthpotential that remains at our Diablillos project. These intercepts continue toconfirm the presence of additional mineralization across Diablillos,and we look forward to incorporating these results into our upcomingMineral Resource estimate. With several zonesdelivering strong grades beyond the existing open pit limits, theProject continues to demonstrate excellent exploration upside.”

Dave O’Connor, Chief Geologist, commented, “Thecontinuity and consistency of the near-surface silver mineralizationwe are seeing south of the JAC open pit is quite remarkable. Withstrong results from both new and existing zones, and severalexploration targets still to be tested, our Phase V drill program willplay a key role in unlocking further upside across the broaderDiablillos system.”

Additional Details on Drill Results

Oculto Northeast Target

A linear, high-grade, gold-dominant mineralized trendextends along the northern margin of the Oculto open pit and continuesseveral hundred metres to the northeast, beyond the current conceptualopen pit boundary. Drill hole DDH 24-074 intersected 10 m grading 1.5g/t gold and 56 g/t silver, confirming the continuity of thismineralized structure.  Additional drilling is planned to furtherdefine and potentially expand this emerging zone.

JAC Extension

The latest drilling confirms that silver mineralizationcontinues to extend south and southwest of the current modeled JACopen pit boundary. These shallow, high-grade intercepts areanticipated to contribute meaningfully to the upcoming MineralResource estimate.  Importantly, mineralization remains open to thesouth, where ongoing Phase V drilling will target further MineralResource growth and continuity.

Exploration Program Update

The recently completed Phase IV exploration programcomprised a total of 21,172 metres drilled across 106 holes.  TheCompany is currently awaiting assay results from the final holes fromthis program, which are expected to be received over the next severalweeks.  All drill results from this program will be incorporated inan updated Mineral Resource estimate scheduled for release in mid-2025and will underpin the Definitive Feasibility Study that has nowcommenced on the Project.

The Phase V drill program is now in progress, withapproximately 20,000 additional metres planned.   Key targetsinclude:

• • The Oculto-JAC epithermal district, focusing on JAC, JAC south extension, Sombra, OcultoNortheast, Oculto East and Laderas targets.

  • The northeast epithermal-porphyry complex, located approximately 4 km northeast of the main Ocultodeposit, including the newly identified CerroViejo gold target, which remains largelyunexplored.

Collar Data

About Diablillos

The Diablillos property is located within the Punaregion of Argentina, in the southern part of Salta Province along theborder with Catamarca Province, approximately 160 km southwest of thecity of Salta and 375 km northwest of the city of Catamarca. Theproperty comprises 15 contiguous and overlapping mineral concessionsacquired by AbraSilver in 2016.  The project site has good year-roundaccessibility through a 150 km paved road, followed by awell-maintained gravel road, shared with other adjacentprojects.

There are several known mineral zones on the Diablillosproperty. Approximately 150,000 m have been drilled to date, which hasoutlined multiple occurrences of epithermal silver-gold mineralizationat Oculto, JAC, Laderas and Fantasma. Several satellite zones ofsilver/gold-rich epithermal mineralization have been located within a500 m to 1.5 km distance surrounding the Oculto/JAC epicentre.  Inaddition, a large porphyry complex is centered approximately 4 kmnortheast of Oculto which includes outcropping porphyry intrusionswithin a major zone of alteration, and associated gold rich epithermalmineralization.

Comparatively nearby examples of high sulphidationepithermal deposits include: La Coipa (Chile); Yanacocha (Peru); ElIndio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero(Argentina); and Filo del Sol (Argentina). The most recent MineralReserve estimate for Diablillos is shown in Table 2:

Table 2 - Diablillos MineralReserve Estimate – As of March 07, 2024

Notes for Mineral Reserve Estimate:

1. Mineral reserves have an effective date of March 7th,2024.

2. The Qualified Person for the Mineral Reserve Estimateis Mr. Miguel Fuentealba, P.Eng.

3. The mineral reserves were estimated using the CanadianInstitute of Mining, Metallurgy and Petroleum (CIM), DefinitionStandards for Mineral Resources and Reserves, as prepared by the CIMStanding Committee on Reserve Definitions and adopted by CIMCouncil.

4. The mineral reserves were based on a pit design whichin turn aligned with an ultimate pit shell selected from a Whittle TMpit optimization exercise. Key inputs for that process are:

• Metal prices of USD $1,750/oz Au; USD $22.50/oz Ag

• Variable Mining cost by bench and material type.Average costs are USD $1.94/t for all lithologies except for“cover”, Cover mining cost of USD 1.73/t, respectively.

• Processing costs for all zone, USD $22.97/t. •Infrastructure and G&A cost of USD 3.32/t. • Pit average slopeangles varying from 37° to 60° depending on the geotechnical domain.• The average recovery is estimated to be 82.8% for silver and 86.6%for gold.

1. The Mineral Reserve Estimate has been categorized inaccordance with the CIM Definition Standards (CIM, 2014).

2. A Net Value per block (“NVB”) cut-off was used toconstrain the Mineral Reserve with the reserve pit 2shell. The NVB wasbased on "Benefits = Revenue-Cost" being positive, where,Revenue = [(Au Selling Price (USD/oz) - Au Selling Cost (USD/oz)) x(Au grade (g/t)/31.1035)) x Au Recovery (%)] + [(Ag Selling Price(USD/oz) - Ag Selling Cost (USD/oz)) x (Ag grade (g/t)/31.1035)) x AgRecovery (%)] and Cost = Process Cost (USD/t) + Transport Cost (USD/t)+ GA Cost (USD/t) + [Royalty Cost (%) x Revenue]. The NVB methodresulted in an average equivalent cut-off grade of approximately 46g/tAgEq.

3. In-situ bulk density was read from the block model,assigned previously to each model domain during the process of mineralresource estimation, according to samples averages of each lithologydomain, separated by alteration zones and subset byoxidation.

4. All tonnages reported are dry metric tonnes and ouncesof contained gold and silver are troy ounces.

5. All figures are rounded to reflect the relativeaccuracy of the estimates. Minor discrepancies may occur due torounding to appropriate significant figures.

QA/QC and Core Sampling Protocols

AbraSilver applies industry standard explorationmethodologies and techniques, and all drill core samples are collectedunder the supervision of the Company’s geologists in accordance withindustry practices. Drill core is transported from the drill platformto the logging facility where drill data is compared and verified withthe core in the trays. Thereafter, it is logged, photographed, andsplit by diamond saw prior to being sampled. Samples are then bagged,and quality control materials are inserted at regular intervals; theseinclude blanks and certified reference materials as well as duplicatecore samples. Groups of samples are then placed in large bags whichare sealed with numbered tags in order to maintain a chain-of-custodyduring the transport of the samples from the project site to thelaboratory.

All samples are sent to the Alex Stewart samplepreparation facility in Jujuy, then the sample pulps are sent to theAlex Stewart laboratory in Mendoza where they are analyzed. Allsamples are analyzed using a multi-element technique consisting of afour-acid digestion followed by ICP/AES detection, and gold isanalyzed by 50g Fire Assay with an AAS finish. Silver results greaterthan 100g/t are reanalyzed using four acid digestion with an ore gradeAAS finish.
