AbraSilver Reports Additional High-Grade Silver and Gold Intercepts Demonstrating Considerable Extension Potential Northeast of the Known Mineralized Zone
Highlight results: 36m @ 399 g/t AgEq (incl. 5m @ 1,645 g/t AgEq), & 45m @ 172 g/t AgEq
Toronto - April 06, 2021: AbraSilver Resource Corp. (TSX.V:ABRA; OTCPK: ABBRF) ("AbraSilver" or the “Company”) is pleased to announce significant high-grade results from the latest assays received from two diamond drill holes completed at the Oculto deposit, located on its wholly owned Diablillos property in the mining-friendly Salta Province, Argentina.
Hole DDH-21-004 is a step-out hole located in the Northeast Zone, a priority growth target for our upcoming Phase II drill program which was announced on April 1, 2021. Importantly the high-grade results from this hole are well beyond the margins of the current Whittle pit, demonstrating considerable extension potential of the mineral resources at Oculto.
Table 1 – Drill Result Highlights (Intercepts greater than 2,000 gram-meter AgEq shown in bold text):
|Drill Hole||From (m)||To (m)||Type||Interval (m)||Ag
|AgEq1 g/t||AuEq1 g/t|
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 continue to intersect multiple high-grade silver and gold zones in effectively every drill hole on the property. We are very excited by the new drill results which demonstrate the potential for a substantial expansion of the Whittle pit towards the northeast where previous broad spaced drilling also intersected high grade gold zones. We plan systematic drilling to develop additional resources in this area, which represents a priority growth target at Oculto.”

Discussion of Drill Hole Results
Hole DDH 21-003 is located in the zone of intersection of the Main and Cross breccias and extends the high-grade silver and gold zone northwards. The multiple high-grade intercepts in this hole are expected to augment the grade of the existing silver resource and also expand the size of the deeper gold zone. Highlight intervals from this hole include:
- 36m @ 370.2 g/t silver with 0.39 g/t gold (from 106 – 142 metres), including 5m @ 1,555.8 g/t silver and 1.17g/t gold in the upper part of a steeply dipping siliceous breccia feeder zone
- 45m @ 146.2 g/t silver with 0.34 g/t gold (from 207 – 252 metres), as well as 1.5m @ 102.5g/t silver and 5.36g/t gold (from 268.5 to 270 metres), in the lower oxide gold zone.

Hole DDH 21-004 is located approximately 200 meters north of the limit of the mineralised zone included in the Whittle pit. It demonstrates the potential for a considerable extension of the Oculto mineralised zone to the northeast where a program of follow up drilling is planned to connect the higher-grade gold intercepts obtained in previous drilling. Highlight intervals from this hole include:
- 17m @ 43.6 g/t silver with 1.56 g/t gold (from 142 – 159 metres)
- 8m @ 81.8 g/t silver with 7.97 g/t gold (from 184 – 192 metres)
- 6m @ 62.7 g/t silver, 4.39 g/t gold, 0.69% copper (from 239 – 245 metres) in the sulphide zone

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.
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.
