AbraSilver Resource Corp. Announces Additional High-Grade Drill Results from Diablillos

JAC Zone:

• Hole DDH 24-038 was drilled in the JAC southwest areaand intersected a broad zone of high-grade silver mineralization, with 62.0 m at 175 g/t Ag, starting at a downhole depth of 85 m.

• Hole DDH 24-039 intersected a broad zone of silver mineralization, with 52.0 m at 42 g/t Ag, starting at a downhole depth of 86 m.

Oculto Northeast:

• Hole DDH 24-034 encountered near-surface gold mineralization with 18.0 m grading 17 g/t Ag and 1.34 g/t Au, starting at a downhole depth of 81 m.

• Hole DDH 24-037 intersected numerous gold and silver zones, including 20.0 m at 21 g/t Ag and 1.30 g/t Au from 148 m down-hole, followed by an interval of 23.0 m at 25 g/t Ag and 1.21 g/t Au.

John Miniotis, President and CEO, commented, "Continuing high-grade silver and gold intercepts from step-out drill holes demonstrates the significant potential for additional Mineral Resource/Reserve growth at Diablillos, and reinforces our confidence in the Project's ability to deliver robust economics and long-term value for our shareholders. With our experienced team and strong project fundamentals in place, we remain very well-positioned for a transformative 2025 and beyond."

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

Note: All results in this news release are rounded. Assays are uncut and undiluted. Widths are drilled widths, not true widths. True widths are estimated to be approximately 80% of the interval widths for oxides.

Dave O'Connor, Chief Geologist, commented, "The intersection of high-grade silver and gold mineralization in these drill holes reinforces our geological model and underscores the exceptional upside at Diablillos. These results show extensions beyond the current Mineral Resource estimates of high-grade mineralization at both the northeast and southwest parts of the Oculto-JAC mineralized system, and we're eager to continuing exploring and advancing this exceptional project."

Additional Details on Drill Results

Figure 2 demonstrates a substantial extension of the southwestern part of the JAC zone which is expected to result in an expanded open pit and an increased Mineral Resource estimate. This expansion underscores the zone's potential for higher-grade mineralization and may significantly enhance the Project's overall value.

Figure 3 highlights the mineralized intercepts in holes DDH 24-034 and DDH 24-037 located in the Oculto Northeast zone. The shallow high-grade gold intercept in hole DDH 24-034 is located above the previously known dominant level of mineralization and confirms the potential to expand the currently defined open pit and with it the Mineral Resources and Reserves. Additional drilling is underway to test the various levels of mineralization in the area for shallow silver and gold mineralization.

Phase IV Exploration Program Update

The ongoing Phase IV drill program is focused on expanding the existing Mineral Resources at a number of target areas with known mineralization as well as exploring newly identified prospective exploration targets within the broader Diablillos land package. The Company continues to have three drill rigs operating, and to date has completed approximately 13,800 metres of drilling in 67 holes. Several assay results are awaited and will be released on an ongoing basis pending review and meeting Company quality assurance-quality control protocols.

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. Additionally, several satellites zones of silver/gold-rich epithermal mineralization have been located within a 500 m to 1.5 km distance surrounding the Oculto/JAC epicentre.

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:

Table 2 - Diablillos Mineral Reserve 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 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.

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

2. 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) + GA Cost (USD/t) + [Royalty Cost (%) x Revenue]. The NVB method resulted in an average equivalent cut-off grade of approximately 46g/t AgEq.

3. 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.

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

5. All figures are rounded to reflect the relative accuracy of the estimates. Minor discrepancies may occur due to rounding to appropriate significant figures.

The Report titled "NI 43-101 Technical Report, Pre-Feasibility Study for the Diablillos Ag-Au Project" is dated April 30, 2024, has an effective date of March 07, 2024, and has the following authors:

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 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.
