AbraSilver Intersects Additional High-Grade Silver and Gold Mineralization: 109m at 292 g/t AgEq, Including 6m at 1,180 g/t AgEq
(TheNewswire)
Additional 250-Metre Step-Out Hole in Northeast zone Intersects: 21m at 6.0 g/t gold-equivalent in oxides
Toronto – TheNewswire - September 16, 2021: AbraSilver Resource Corp. (TSXV:ABRA) (OTC:ABBRF) ("AbraSilver" or the “Company”) is pleased to report additional high-grade drill results from the latest diamond drill holes of the Company’s ongoing Phase II drill program, on its wholly-owned Diablillos property in Salta Province, Argentina.
Hole DDH 21-038 was drilled in the Tesoro zone as part of a program to continue to upgrade Indicated Resources to the Measured category, while hole DDH 21-039 was drilled in the Northeast zone approximately 250 metres beyond the open pit resource shell. Assay results from the two key highlight holes are summarized in Table 1 below, with results from all additional holes included in Table 2.

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 additional information.
John Miniotis, President and CEO, commented, “Today’s announcement demonstrates further continuity of high-grade gold mineralization for hundreds of metres beyond the open pit resource in the Northeast Zone. Yesterday we announced that M&I Resources at Oculto increased by 37% for gold and 11% for silver. We remain highly encouraged by the results from our ongoing Phase II drill program which clearly demonstrates significant potential for additional mineral growth.”

Discussion of Drill Hole Results
Hole DDH 21-038 was drilled in the high-grade Tesoro zone in order to upgrade more high-grade Indicated resources to the Measured category. This hole intersected 109.3 metres of 176.8 g/t silver and 1.53 g/t gold from 112 to 221.3 metres, including 25.7 metres of 125.0 g/t silver and 5.20 g/t gold within the oxide zone. In the silver enriched layer, a significant high-grade interval of 6 metres of 1,164 g/t silver and 0.21 g/t gold was encountered. These intercepts support the continuity of the shallowly dipping secondary enriched silver layer and the underlying gold dominant layer that extend within the mineralised system.
DDH 21-039 was drilled in the Northeast zone approximately 250 metres beyond the open pit resource shell. The hole has numerous intercepts with significant gold and silver mineralisation over substantial widths, including 21.0 metres of 50.6 g/t silver and 5.30 g/t gold from 194 to 215 metres. This is a part of a robust mineralised system associated with silicification and fracturing in the oxide zone extending northeast of the Oculto resources.
Systematic drilling is ongoing as part of the Phase II drill program aimed at further expanding the recently announced updated Mineral Resource Estimate (see news release dated September 15, 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: Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo del Sol (Argentina)

Effective September 8, 2021. The resource estimate is N.I. 43-101 compliant. Full details of the Mineral Resources are available in a Company news release dated September 15, 2021. The full technical report, which is being prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI-43-101”) by Mining Plus, will be available on SEDAR (www.sedar.com) under the Company’s issuer profile within 45 days of the news release dated September 15, 2021.
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. No metallurgical testwork has yet been completed on the recovery of copper.
About AbraSilver
AbraSilver is a well-funded silver-gold focused advanced-stage exploration company. The Company is rapidly advancing its 100%-owned Diablillos silver-gold project in the mining-friendly Salta province of Argentina, which has a Measured and Indicated resource base of over 160Moz on a silver-equivalent basis or 2.3Moz on a gold-equivalent basis. The Company is led by an experienced management team and has long-term supportive shareholders including Mr. Eric Sprott 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. AbraSilver is listed on the TSX-V under the symbol “ABRA” and in the U.S. under the symbol “ABBRF”.
