AbraSilver Reports Continued Drilling Success at Diablillos with High-Grade Intercepts Including 52.8 Metres at 286 g/t AgEq & 15 Metres at 711 g/t AgEq



 

Toronto – TheNewswire - March 29, 2021 - AbraSilver Resource Corp. (TSXV:ABRA); (OTC:ABBRF) ("AbraSilver" or the “Company”) is pleased to announce that it continues to intersect significant high grade silver and gold mineralization from infill and step out surface drilling on the Oculto deposit, demonstrating the continuity and overall robustness of the large-scale, high-grade Diablillos project.

The drill results continue to successfully achieve all three of the Company’s key exploration objectives:

  • - Expanding the resources in the deeper gold zone (Hole DDH-21-002);

    - Expanding the resource base to the northeast beyond the current Whittle Pit (Holes 20-028 and 20-030); and

    - Outlining shallow gold resources (various holes).

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.

1 AgEq & AuEq calculations for reported drill results are based on USD $20.00/oz Ag, $1,500/oz Au and $3.00/lb Cu. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices. Refer to Technical Notes below for metallurgical recoveries assumed in the 2018 PEA study on Diablillos.

John Miniotis, President and CEO, commented, “It’s quite remarkable that we’re encountering high-grade silver and gold intercepts in practically every hole we drill at Oculto.  Once again, we’re extremely pleased with the new drill results, which continue to augment the grade of the existing silver resource, expand the deeper gold zone, and demonstrate the potential for a substantial expansion of the Whittle Pit towards the northeast.

These consistent high-grade results over significant widths should help considerably increase the contained ounces in our updated Mineral Resource statement expected later this year.”

Discussion of Drill Hole Results

Hole DDH 21-002 intersected 10 meters grading 1,004 g/t silver in the upper silver zone, as well as a separate interval of 52 meters at 127 g/t silver and 2.13 g/t gold (including 20 meters at 184 g/t silver and 3.19g/t gold) in the lower oxide gold zone. This hole augments the grade of the silver resource and expands the size of the deeper gold zone.

Holes DDH 20-028 and DDH 20-030 were both drilled on section 8450 to explore the area northeast of the Whittle Pit boundary. These holes intersected numerous zones of oxide gold and silver mineralisation that substantially expand the potential resource base, including:

Hole DDH-20-028

  • - 11.0 m @ 89.15 g/t silver and 1.17 g/t gold (from 70 - 81 metres down hole)

    - 3.0 m @ 37.4 g/t silver and 5.52 g/t gold (from 139 - 142 metres)

        including: 1.0 m @ 65.8 g/t silver and 12.80 g/t gold (from 141 - 142 metres)

 

Hole DDH-20-030

  • - 12.5 m @ 32.94 g/t silver and 4.68 g/t gold (from 205.5 - 218 metres)

    - 4.5 m @ 11.37 g/t silver and 3.19 g/t gold, in underlying sulphide mineralisation

These intercepts demonstrate the potential for additional gold and silver mineralisation in the northeast zone. A program of follow-up drilling is planned in this mineralised zone which extends for more than 500 meters beyond the Whittle Pit boundary.

Shallow Intercepts

Several holes in this announcement were also aimed at expanding the shallow mineralised zone that was previously classified as waste rock. These intercepts are expected to form part of a shallow resource that could considerably further improve the economics of an open pit. Notable intercepts include:

  • - Hole DDH-20-028: 11m @ 89.15 g/t silver with 1.17 g/t gold (from 70 – 81 metres)

    - Hole DDH 20-032: 17m @ 8.21 g/t silver with 1.63 g/t gold (from 56 – 73 metres), and 14.0m @ 69.84 g/t silver (from 75 to 89 metres)

    - Hole DDH 21-001: 46m @ 69.80 g/t silver with 0.84 g/t gold (from 33 to 79 metres), including 5.5m @ 87.60g/t silver with 2.45g/t gold (33 to 38.5 metres)

    - Hole DDH 21-002: 10m @ 41.6g/t silver with 1.76g/t gold (from 71 to 81 metres)

Exploration Program Update

To date the company has reported results from a total of 34 diamond drill holes, with results from an additional 13 holes currently pending from the assay laboratory.  The results from all drill holes will be incorporated into an updated Mineral Resource estimate which remains on-track to be announced in mid-2021.

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 approximately 90,000 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: El Indio, Chile; Veladero, Argentina; and Pascua Lama, on the Chile-Argentine border.

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.

Qualified Persons

David O’Connor P.Geo., Chief Geologist for AbraSilver, is the qualified person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects, has reviewed and approved the scientific and technical information in this news release.

 

Technical Notes

All results in this news release are rounded. Assays are uncut and undiluted. Intervals are drilled widths, not true widths. AgEq calculations for reported drill results are based on USD $20.00/oz Ag, $1,500/oz Au and $3.00/lb Cu. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices.  The most recent technical report for the Diablillos Project is the 2018 Preliminary Economic Assessment (PEA) authored by Roscoe Postle Associates Inc.  The PEA assumes average metallurgical recoveries of 82% Ag and 86% Au.  No metallurgical testwork has yet been completed on the recovery of copper.
