AbraSilver Expands Gold Mineralization at

Oculto East with Broad Step-Out Intercepts

Highlight Intercept of 171 Metres Grading 0.83 g/t Gold,

Including 9 Metres at 3.46 g/t Gold

Toronto, Ontario--(Newsfile Corp. - April 13, 2026) -

AbraSilver Resource Corp. (TSX: ABRA)

(OTCQX: ABBRF)

("AbraSilver" or the "Company") is pleased to report new assay results from four

diamond drill holes from the ongoing Phase VI drill program at its wholly-owned Diablillos project in

Argentina (the "Project").

The latest results from the Oculto East target area continue to demonstrate strong potential to expand

mineralization beyond the current open pit constrained Mineral Resource estimate.

Highlight Drill Results:

Widths are reported as drilled; true widths are not yet known.

Hole DDH 26-008

encountered a broad, continuous zone of gold-dominant mineralization,

returning

171.0 metres ("m) grading 0.83 g/t gold and 10.3 g/t silver

from 230 m downhole,

including:

9.0 m at 3.46 g/t gold and 16.0 g/t silver

The hole also encountered a shallow

20.0 m zone grading 0.35 g/t gold and 57.0 g/t

silver

from only 79 m downhole

Hole DDH 26-006

intersected multiple mineralized intervals, including a broad zone of

56.0 m

grading 0.29 g/t gold and 8.0 g/t silver

from 109 m downhole

John Miniotis, President and CEO, commented, "The ongoing results from Oculto East continue to

demonstrate the strong potential to expand mineralization beyond the current Mineral Resource and

conceptual open pit limits. The consistency of broad gold-dominant intercepts, along with higher-grade

intervals, reinforces our confidence in the scale of the system and highlights the significant opportunity for

continued Mineral Resource growth."

Dave O'Connor, Chief Geologist, commented, "Drilling at Oculto East continues to intersect broad zones

of oxide gold and silver mineralization beyond the current Mineral Resource boundary. The presence of

higher-grade intervals within these broader zones supports our geological interpretation and highlights

the potential to increase Mineral Resources in this area."

Details on Drill Results - Oculto East

Oculto East remains the primary focus of the ongoing Phase VI drill program, with results to date

highlighting the potential for meaningful Mineral Resource expansion.

The latest drill results continue to confirm that mineralization extends several hundred metres east of the

currently defined open pit margin, with the system remaining open along strike and at depth.

Hole DDH 26-008 returned the strongest intercept, demonstrating a thick, continuous zone of gold-

dominant mineralization with localized higher-grade intervals, highlighting both scale and grade

continuity. Hole DDH 26-006 intersected multiple mineralized zones closer to surface, supporting lateral

continuity of mineralization across the target area.

Additional drill holes completed in this area also intersected broad zones of gold and silver

mineralization, consistent with the Company's geological model and reinforcing the potential for

continued expansion at Oculto East.

About Diablillos

The Diablillos property is located within the Puna region of Argentina, in the southern part of Salta

Province along the border with Catamarca Province, approximately 160 km southwest of the city of Salta

and 375 km northwest of the city of Catamarca. AbraSilver acquired the property in 2016, which

comprises 15 contiguous and overlapping mineral concessions with excellent year-round road access.

Exploration to date has outlined multiple occurrences of silver-gold oxide mineralization at Oculto, JAC,

Laderas, and Fantasma, located within a 500 m to 1.5 km distance surrounding the Oculto/JAC

epicentre. To date, over 150,000 metres have been drilled on the property, which continues to

demonstrate the strong growth potential of shallow, oxide-hosted silver and gold resources.

In addition, a

large porphyry complex is centered approximately 4 km northeast of Oculto which includes outcropping

porphyry intrusions within a major zone of alteration and associated gold rich epithermal mineralization.

Comparatively nearby examples of high sulphidation epithermal deposits include: La Coipa (Chile);

Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo

del Sol (Argentina). The most recent Mineral Resource estimate for Diablillos is shown in Table 2:

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

best 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 at site; these include blanks and certified reference materials as well as

duplicate core samples which are collected in order to assess sampling precision and reproducibility.

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 ASA (Alex Stewart Argentina) preparation laboratory in Salta, where

they are prepared, then the pulp sachet is directly dispatched to its facility in Mendoza, Argentina, 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 re-analyzed using four acid digestion with an ore grade AAS finish.
