AbraSilver Further Expands High-Grade Silver Mineralization Beyond JAC Boundary at
Diablillos; Including 65.0 Metres Grading 162 g/t Ag
Toronto – April 29, 2025: AbraSilver Resource Corp. (TSX: ABRA; OTCQX: ABBRF) (“AbraSilver”
or the “Company”) is pleased to report additional encouraging drill results from its wholly-owned Diablillos
project in Argentina (the “Project”).
The latest drill results from the JAC Extension zone continue to demonstrate multiple high-grade, near-
surface silver intercepts beyond the current conceptual open pit limits. These assays represent the final
results from the successful Phase IV exploration campaign. All Phase IV drill results, which comprised
a total of 21,172 metres, will be incorporated into an updated Mineral Resource estimate, which remains
on schedule for release in mid-2025.
The Company remains very well-positioned to continue delivering exploration success, with a fully-funded
Phase V drill campaign, already well-underway, targeting several high-priority zones across the Diablillos
project.
Key highlights from the latest assay results include:
Latest Phase IV JAC Extension Drilling:
Hole DDH 25-001: 56.0 metres (“m”) at 107 g/t Ag, starting at 66 m down-hole depth, including
6.0 m at 181 g/t Ag.
Hole DDH 25-002: 65.0 m at 162 g/t Ag, from 82 m depth, including 12.0 m at 405 g/t Ag.
Hole DDH 25-005: 63.0 m at 139 g/t Ag, from 74 m depth, including 26.0 m at 244 g/t Ag.
Hole DDH 25-006: 88.0 m at 89 g/t Ag, from 52 m depth, including 6.0 m at 200 g/t Ag.

Hole DDH 25-015: 35.0 m at 91 g/t Ag, from 81 m depth, including 2.0 m at 385 g/t Ag.
Hole DDH 25-017: 43.0 m at 134 g/t Ag, from 100 m depth.
John Miniotis, President and CEO, commented, “We are very pleased with the final results from our highly
successful Phase IV program, which continue to demonstrate significant growth potential beyond the
current open pit boundaries. With all Phase IV results now received, we look forward to updating our
Mineral Resource estimate, which is expected to further enhance the scale and quality of the Diablillos
project.”
Dave O’Connor, Chief Geologist, commented, “The latest drill results confirm the presence of strong
silver grades over broad widths at shallow depths, further reinforcing the outstanding potential of the JAC
deposit. We are excited to continue building on this momentum with our Phase V drill program, which is
designed to systematically test the multiple high-priority targets across the property, and build on the
success of our prior campaigns.”

Additional Details on Drill Results
JAC Extension
Drilling at the JAC Extension zone has successfully expanded silver mineralization both beneath and
along the edges of the current conceptual open pit. Results from these final Phase IV drill holes, together
with previous silver intercepts, will be incorporated into an updated Mineral Resource estimate that will
underpin the ongoing Definitive Feasibility Study. The mineralization at JAC remains open towards the
south and west, and ongoing drilling is continuing to test the potential for further Mineral Resource growth
in this area.

Figure 3 – Section Through JAC Holes from Table 1 Looking East
The composite section through drill holes shown in Figure 3, above, may give the impression that several
intercepts lie within the conceptual pit boundary, however, this is due to the section being a composite
view. A detailed section through, for example, DDH 25-002 (shown in Figure 4), indicates that the
intercept is actually located outside the current proposed pit shell.

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. The property comprises 15 contiguous and overlapping
mineral concessions acquired by AbraSilver in 2016. The project site has good year-round accessibility
through a 150 km paved road, followed by a well-maintained gravel road, shared with other adjacent
projects.
There are several known mineral zones on the Diablillos property. Approximately 150,000 m have been
drilled to date, which has outlined multiple occurrences of epithermal silver-gold mineralization at Oculto,
JAC, Laderas and Fantasma. Several satellite zones of silver/gold-rich epithermal mineralization have
been located within a 500 m to 1.5 km distance surrounding the Oculto/JAC epicentre. 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 Reserve estimate for Diablillos is shown in Table 2:

Notes for Mineral Reserve Estimate:
1. Mineral reserves have an effective date of March 7th, 2024.
2. The Qualified Person for the Mineral Reserve Estimate is Mr. Miguel Fuentealba, P.Eng.
3. The mineral reserves were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), Definition Standards for Mineral
Resources and Reserves, as prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.
4. The mineral reserves were based on a pit design which in turn aligned with an ultimate pit shell selected from a Whittle TM pit 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 slope angles 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.
5. The Mineral Reserve Estimate has been categorized in accordance with the CIM Definition Standards (CIM, 2014).
6. A Net Value per block (“NVB”) cut-off was used to constrain the Mineral Reserve with the reserve pit 2shell. The NVB was based 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 Ag Recovery (%)] and Cost = Process Cost
(USD/t) + Transport Cost (USD/t) + G&A Cost (USD/t) + [Royalty Cost (%) x Revenue]. The NVB method resulted in an average equivalent cut-
off grade of approximately 46g/t AgEq.
7. In-situ bulk density was read from the block model, assigned previously to each model domain during the process of mineral resource
estimation, according to samples averages of each lithology domain, separated by alteration zones and subset by oxidation.
8. All tonnages reported are dry metric tonnes and ounces of contained gold and silver are troy ounces.
9. All figures are rounded to reflect the relative accuracy of the estimates. Minor discrepancies may occur due to rounding to appropriate
significant figures.
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.
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 sent to the Alex Stewart sample preparation facility in Jujuy, then the sample pulps are
sent to the Alex Stewart laboratory in Mendoza 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.
