CEO.CA Chairman's Briefing

(TheNewswire)

Toronto, ON - TheNewswire - May 4, 2023 - AbraSilver Resource Corp. (TSX.V:ABRA) (OTC:ABBRF) (“AbraSilver” or the “Company”) is pleased to announce its latest diamond drilling assay results holes from the ongoing Phase III exploration program on the Company’s wholly-owned Diablillos property in Salta Province, Argentina (“Diablillos” or the “Project”).

Drilling at the JAC zone continues to consistently intersect high-grade silver oxide mineralization, with associated gold in some areas, at shallow depths, as well as underlying copper and silver mineralization in sulphides. The JAC zone remains open along strike towards the southwest and in other directions.

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.

          1AgEq based on 81.9(Ag):1(Au) calculated using long-term prices of US$25.00/oz Ag and US$1,750/oz Au, and 73.5% process recovery for Ag, and 86.0% process recovery for Au as demonstrated in the Company’s Preliminary Economic Assessment in respect of Diablillos dated January 13, 2022, using formula:  AgEq g/t = Ag g/t + Au g/t x (Gold Price/Silver Price) x (Gold Recovery/Silver Recovery).  

Key takeaways from the latest JAC zone drill results include:

• DDH 23-017was drilled to test the southwest extension of the JAC zone and intersected several zones of silver mineralization in oxides, with 12.0 metres grading 876.1 g/t Ag from a downhole depth of 92.0 metres downhole, including 2.0 metres grading 4,968.4 g/t Ag and 0.14 g/t Au. 

• DDH 23-020 was drilled towards the northern margin of the JAC zone and intersected several zones of silver and gold mineralization in oxides, including 19 metres at 149.5 g/t Ag and 0.78 g/t Au from 127.0 metres downhole. 

• DDH 23-021, located in the southeastern part of the drill target area, encountered high-grade silver mineralization in oxides, intersecting 32.0 metres grading 530.8 g/t Ag and 0.60 g/t Au from 161.5 metres downhole.  This high-grade intercept further demonstrates the importance and continuity of the deeper layer of silver-gold mineralisation at JAC. 

  • Immediately beneath this high-grade oxide intercept, the hole encountered 6.0metres grading 1.32% Cu and 52.6 g/t Ag in sulphide mineralization, demonstrating the potential of mineralised feeder structures at JAC to host substantial sulphide mineralisation. 

• DDH 23-023, located in the northwestern part of the drill target area shows continuity of silver dominant mineralisation along the northern margin of the deposit.  The hole intersected59.5 metres grading 103.4 g/t Ag and 0.05 g/t Au starting from a depth of only 50.5 metres.

John Miniotis, President and CEO, commented, “Our drill results continue to encounter multiple thick intercepts of oxide silver in virtually every hole as we increase confidence and extend the size of the new high-grade JAC discovery.  The JAC zone features a highly attractive combination of scale, grade and continuity, which is expected to significantly increase the economics of our Diablillos project.  We look forward to additional drill results and incorporating all the data into an updated Mineral Resource estimate later this year.”

Dave O’Connor, Chief Geologist, commented, “Today’s drill results further define and expand the high-grade core area of the new JAC zone.  Additionally, the contact zone between the oxides and underlying sulphides continues to show substantial potential for an extensive zone of high-grade silver dominant mineralisation at the base of the oxide zone as well as for significant underlying copper sulphide mineralisation with associated precious metal content.”

Exploration Update  

Drilling activity at Diablillos remains focused on the recently discovered JAC zone which is located several hundred metres southwest of the conceptual open pit that constrains the current Mineral Resource estimate (“MRE”) on the main Oculto deposit (M&I MRE containing 1.3 Moz gold and 109 Moz silver – Table 2).  

To date, the Company has completed approximately 20,000 metres of drilling in 85 holes, as part of the planned 22,000-metre Phase III program that is primarily targeting the JAC zone.  The Phase III exploration drill program will form the basis for an updated MRE and will be included in a Pre-Feasibility Study on the Diablillos project, which the Company expects to complete in the second half of 2023.  Planned drilling will also test the margins of the JAC zone to provide data for geotechnical studies for a conceptual open pit at the JAC zone.  

Additional exploration targets have been identified to the southwest of the Oculto MRE based on the recently completed detailed ground magnetic survey. Some of these targets, including the Fantasma and Alpaca targets, are expected to be drilled following the systematic drilling of the JAC zone.

At the La Coipita project, a deep hole was completed down to a depth of 1,242 metres.   The Company has completed final core splitting and has sent final sample shipments to the laboratory. Assay results are expected to be received around late June and will be reported once they are received and interpreted.

Collar Data

About Diablillos

The 80 km2 Diablillos property is located in the Argentine Puna region - the southern extension of the Altiplano of southern Peru, Bolivia, and northern Chile - and was acquired from SSR Mining Inc. by the Company in 2016.  There are several known mineral zones on the Diablillos property, with the Oculto zone being the most advanced with over 120,000 metres drilled to date.  Oculto is a high-sulphidation epithermal silver-gold deposit derived from remnant hot springs activity following Tertiarty-age local magmatic and volcanic activity. Comparatively nearby examples of high sulphidation epithermal deposits include: Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo del Sol (Argentina).

The most recent Mineral Resource estimate for the Oculto Deposit is shown in Table 2:

Table 2 - Oculto Mineral Resource Estimate – As of October 31, 2022

Notes: Effective October 31, 2022. Mineral Resources are not Mineral Reserves and have not demonstrated economic viability. The Mineral Resource estimate is N.I. 43-101 compliant and was prepared by Luis Rodrigo Peralta, B.Sc., FAusIMM CP(Geo), Independent Consultant. The mineralization estimated in the Mineral Resource is sub-horizontal with sub-vertical feeders and a reasonable prospect for eventual economic extraction by open pit methods.

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 received by the SGS offices in Salta who then dispatch the samples to the SGS preparation facility in San Juan. From there, the prepared samples are sent to the SGS laboratory in Lima, Peru 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.
