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.
