Latest Results Include 30 Metres Grading 237 g/t Silver Beyond the JAC Pit Boundary  

Toronto – March 11, 2025 – TheNewswire – AbraSilver Resource Corp. (TSX: ABRA; OTCQX: ABBRF) (“AbraSilver” or the “Company”) is pleased to announce new assay results from the recently completed Phase IV drill program on its wholly-owned Diablillos project in Argentina (the “Project”).   The latest drill results confirm significant high-grade silver and gold mineralization across multiple zones, including Oculto Northeast, JAC Extension and the recently discovered Sombra zone.  These findings reinforce the Project’s strong potential for further Mineral Resource expansion.  Key highlights include:

Sombra Target:

• Hole DDH 24-069 intersected 17.0 m grading 101 g/t Ag, starting at a shallow depth of only 38.0 m down-hole.  This includes a higher-grade interval of 205 g/t Ag over7.0 m.  

Oculto Northeast:

• Hole DDH 24-070, drilled approximately 50 m beyond the Oculto open pit boundary, returned 17.0 m grading 1.80 g/t Au and 39 g/t Ag in oxides, startingfrom a down-hole depth of 151.0 m. Thisincludes a higher-grade interval 4.4 m grading 3.30 g/t Au and 28 g/t Ag.  

JAC Extension:

• Hole DDH 24-072, drilled 50 m beyond the JAC open pit boundary, encountered 22.0 m at 168 g/t Ag,  starting at a down-hole depth of 102.0 m.   

• Hole DDH 24-073, drilled 50 m beyond the current JAC open pit boundary, intersected 35.5 m grading 56 g/t Ag, beginning at a down-hole depth of 105.0 m. 

• Hole DDH 24-075, drilled 25 m beyond the JAC open pit boundary, returned 30.0 m at 237 g/t Ag, starting at 125.5 m down-hole depth. Additional drilling is planned to further delineate the extent and continuity of mineralization located south of the JAC zone.

Additional Details on Drill Results

Sombra Target  

The Sombra target is based on an east-northeast trending zone of low magnetic intensity, which runs parallel to the Oculto-JAC trend. To date, Abrasilver has drilled five holes in this target, with four intersecting silver mineralization. The latest results include drill hole DDH 24-069, which returned 17.0 m grading 101 g/t silver, including a higher-grade interval of 205 g/t silver over 7.0 m. The mineralization is covered by only approximately 40 metres of unconsolidated colluvium, making it easily exploitable. Systematic drilling will be conducted to determine the extent and grade of this newly discovered zone as a part of the Phase V exploration drill program.

Oculto Northeast Target  

A linear, high-grade, gold dominant mineralized trend runs along the northern margin of the Oculto open pit and extends several hundred metres northeast, beyond the current modeled open pit boundary. Drill hole DDH 24-070 intersected 17m grading 1.8 g/t gold and 39 g/t silver, including 4.4m grading 3.30 g/t gold and 28 g/t silver. These results demonstrate the continuity of high-grade mineralization along this trend. Under Phase V, drilling will continue in this area, aiming to expand the known Mineral Resource.

JAC Extension

These drilling results confirm that mineralization extends yet further south and southwest of the modeled JAC open pit boundary. The updated Mineral Resource estimate, to be completed ahead of the upcoming Definitive Feasibility Study, is expected to incorporate shallow silver mineralization in these areas. Notably, hole DDH 24-075 intersected 30.0m grading 237 g/t silver, including 11.5m grading 417 g/t silver. The mineralization remains open, particularly to the south of JAC, and planned drilling as a part of the Phase V program will further define these extensions.

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

 

Category	Tonnage (000 t)	Ag (g/t)	Au (g/t)	Contained Ag (000 oz Ag)	Contained Au (000 oz Au)
Proven	12,364	118	0.86	46,796	341
Probable	29,930	80	0.80	76,684	766
Proven & Probable	42,294	91	0.81	123,480	1,107

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. 

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.
