AbraSilver Reports Multiple High-Grade Silver & Gold Intercepts Including 82 Metres at 4.1 g/t Gold-Equivalent (305 g/t Silver-Equivalent)
- DDH 21-014 was drilled to test the north-eastern extension of the Oculto deposit and intersected various broad high-grade intervals including: 77m at 202 g/t AgEq (2.70 g/t AuEq) from a depth of 79m downhole, as well as a deeper interval of 65m at 217 g/t AgEq (2.89 g/t AuEq)
- DDH 21-015 was drilled in the high-grade Tesoro zone and intersected a wide high-grade gold intercept of 82m at 305 g/t AgEq (4.07 g/t AuEq) including 3m at 2,014 g/t AgEq (26.85 g/t AuEq)
Toronto - June 01, 2021: AbraSilver Resource Corp. (TSX.V:ABRA; OTCPK: ABBRF) ("AbraSilver" or the “Company”) is pleased to report continued high-grade drill results received from three additional diamond drill holes completed on its wholly-owned Diablillos property in Salta Province, Argentina.

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, “We are thrilled by the exciting results that we continue to receive from our Phase I exploration program. These latest results demonstrate the continuity of high-grade silver and gold mineralisation in the Tesoro Zone, as well as the strong potential to add resources in the Northeast gold zone, well beyond the existing open pit margin. We look forward to reporting more assays in the coming weeks and announcing the updated resource estimate and PEA study in the third quarter.”
David O’Connor, Chief Geologist, commented, “Now that we have completed the 15,000-meter Phase I drilling program at Oculto on which the updated resource estimate will be based, we are very excited to be proceeding with drilling other targets within the Diablillos area where previous exploration has shown potential for additional gold dominant zones. Success in these peripheral areas would add substantially to the resource base at Oculto and further improve the economics of the project considerably."
Discussion of Drill Hole Results
Hole DDH 21-013 was drilled to test the northeast mineralised zone several hundred meters beyond the open pit margin. The hole intersected 33.0 meters of 0.92 g/t gold and 12.6 g/t silver (from 236 to 269 meters down hole depth), including 4 meters of 2.99 g/t gold and 21.0 g/t silver (from 236 to 240 meters). This hole demonstrates a mineralised structure that will be followed up as part of the Phase II drill program.
Hole DDH 21-014 was drilled to test the north-eastern extension of the Oculto mineralised system. The hole intersected substantial zones of high-grade oxide gold and silver mineralisation, with 77.0 meters of 0.71 g/t gold and 149.1 g/t silver (from 79 to 156 meters), including 7.0 meters of 2.63 g/t gold and 970 g/t silver and (from 91 to 98 meters). A deeper zone of higher grade gold mineralisation with 65.0 meters of 2.68 g/t gold and 15.9 g/t silver occurs from 282.0 to 347.0 meters, which includes several higher grade intercepts grading upto 1.0 meter of 20.47 g/t gold and 38.9 g/t silver. This hole shows the continuation of high-grade gold dominant mineralisation extending north-east of the Tesoro Zone.
Hole DDH 21-015 was drilled in the Tesoro Zone and intersected high-grade gold and silver mineralisation, with 82.0 meters of 2.75 g/t gold and 104.5 g/t silver (from 120 to 202 meters), including 26.0 meters of 4.79 g/t gold and 140 g/t silver. This hole shows an extension of gold rich mineralisation towards the west and is expected to add to the enhanced grade estimate of the Tesoro Zone.

Exploration Program Update
To date the company has reported results from a total of 48 diamond drill holes, with results from the final 5 holes from the 15,000-meter Phase I exploration program expected to be received shortly. All of the drill results from the Phase I program will be incorporated into an updated resource estimate which is expected to be announced in Q3/2021.
The Company’s Phase II exploration program is now well underway and will consist of a minimum of 10,000-meters of diamond drilling. Both drill rigs are now testing the continuity of gold mineralisation towards the northeast of the Oculto deposit in an attempt to extend the Whittle Pit boundary, following which additional targets peripheral to the Oculto zone will be explored.

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: Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo del Sol (Argentina)

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.
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.
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.
AbraSilver is a well-funded silver-gold focused advanced-stage exploration company.

The Company is led by an experienced management team and has long-term supportive shareholders including Mr. Eric Sprott, Altius Minerals and SSR Mining. In addition, AbraSilver owns a portfolio of earlier-stage copper-gold projects, including the Arcas project in Chile where Rio Tinto has an option to earn up to a 75% interest by funding up to US$25 million in exploration.
