CEO.CA Chairman's Briefing

(TheNewswire)

Toronto – October 23, 2024 – TheNewswire: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) (“AbraSilver” or the “Company”) is pleased to announce assay results from the ongoing, fully-funded 20,000 metre (“m”) Phase IV drill program, on its wholly-owned Diablillos project in Argentina (the “Project”).  Key highlights from the latest drill assay results include:

Oculto Northeast:

• Hole DDH 24-031 was designed to expand the existing known shallow mineralization beyond the open pit margin at Oculto Northeast. Drilling encountered high-grade silver mineralization with 15.0 m grading 496 g/t Ag and 0.28 g/t Au, starting at a downhole depth of 152 m, within which was 5.7 m grading 1,151 g/t Ag and 0.22 g/t Au.  

Extension of JAC Zone:

• Hole DDH 24-033 was a step-out hole in the JAC southwest area that was drilled to extend the existing Mineral Resources beyond the current open pit boundary. Drilling intersected a broad zone of high-grade mineralization, with 50.0 m at 250 g/t Ag, starting at a downhole depth of 110 metres and included an interval of 5.0 m grading 1,036 g/t Ag 

New Discovery Area (Sombra Target):

• Hole DDH 24-036 was the first reconnaissance hole targeting a brand new zone, named the Sombra target, located approximately 500 metres to the southeast of Oculto and JAC, that is believed to run parallel to the existing Mineral Resources.  

• Drilling intersected mineralization near-surface, with 22.0 m at 40 g/t Ag starting at a downhole depth of only 42.5 m marking a successful initial test of this new exploration area.  Additional drilling is now planned to test the extent of mineralization in this new silver zone.   

The Company is also pleased to announce the commencement of drilling of an initial exploration hole situated on the Diablillos Porphyry Complex, located approximately 3.5 km northeast of the Oculto deposit.  The initial hole is in the Cerro Viejo target area and is designed to test the potential for a large copper-gold-molybdenum porphyry system.   A minimum of three priority holes have been selected to be drilled targeting coincident chargeability and resistivity zones, defined by the recently completed geophysical survey detailed by the Company in its press release dated September 30, 2024.

John Miniotis, President and CEO, commented, “These exceptionally high-grade silver intercepts at both the JAC and Oculto Northeast areas reinforce the potential for significant Mineral Resource growth at our world-class Diablillos project.  Additionally, we are very pleased that the first reconnaissance drill hole at the new and nearby Sombra target successfully intersected silver mineralization, suggesting that this area holds great potential for future exploration.”

Dave O’Connor, Chief Geologist, commented, “We are very excited by these latest drill results, which continue to demonstrate strong continuity of high-grade silver mineralization beyond the existing boundaries at both the northeastern and southwestern parts of the Oculto-JAC mineralized system.  Moreover, the identification of the new Sombra target, and the commencement of drilling at the porphyry complex also represent significant milestones as we continue to expand the mineralization footprint across Diablillos.”

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

Additional Details on Drill Results

Hole DDH 24-033 in Figure 2 below, shows the 50.0 metre intercept of 250.2 g/tAg beyond the open pit margin defined in the latest Pre-Feasibility Study and reinforces the potential to increase the Mineral Resources and Reserves at the JAC deposit.   Additional drilling is currently underway along this trend.

Figure 3 shown below highlights the mineralized intercept in hole DDH 24-031 located in the Oculto Northeast zone.   The intercept is situated 150 – 200 metres above the previously known dominant level of mineralization and confirms the continuity of a shallow, silver enrichment zone.   The section demonstrates 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 shallower silver mineralization and a potentially higher-grade gold zone beneath.

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 11,560 metres of drilling in 58 holes.  Several assay results are awaited and will be released on an ongoing basis pending review and meeting Company quality assurance-quality control protocols.

Collar Data

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.

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.
