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, “Our drill results continue to demonstrate both the continuity and growth potential of the high-grade silver and gold mineralization at the Tesoro zone, as well as adding to the potential resources of the northeast gold zone beyond the open pit margin.
The Tesoro zone is the highest-grade area within the broader Oculto deposit. The consistent high-grade results we keep encountering, continue to support our view that excellent potential exists to significantly grow the tonnage and grades of the existing Mineral Resources. We look forward to receiving exploration results from our remaining 8 holes of the Phase I drill program, culminating in a resource update in Q3.”

Discussion of Drill Hole Results
Hole DDH 21-012 was drilled to test the newly-named Tesoro zone (ie. the intersection of the Main and Cross breccias). The hole intersected high grade gold and silver mineralisation, with 104 meters of 2.21 g/t Au and 216.2 g/t Ag from 134 to 238 meters down hole depth, including 47 meters of 4.26 g/t Au and 280.2 g/t Ag from 172 to 219 meters.
Hole DDH 21-012 is located on section line 8275 in the Tesoro Zone, between holes DDH 20-026 (section line 8,200) and DDH 20-027 (section line 8,300), both of which intersected thick zones of high-grade gold and silver mineralisation. This new intercept demonstrates continuity of the high-grade zone and should add substantially to the silver and gold resources in the Tesoro Zone.
Importantly, the Tesoro zone is not only expanding resources it is doing so within the existing open pit footprint. As such, the Company expects to add meaningful ounces at materially higher grades within the existing open pit resource used in the 2018 PEA study.

Hole 21-011 was drilled to test the Northeast zone of the Oculto deposit. It intersected zones of moderate grade oxide gold and silver mineralisation together with higher grade sulphide mineralisation beyond the Whittle pit margin defined in the 2018 PEA, with 18.5 meters of 1.70g/t gold and 61.3g/t silver from 235.5 to 254.0 meters down hole depth, including 6.5 meters of 4.22g/t gold and 85.4g/t silver from 247.5 to 254 meters. This hole shows the continuation of gold dominant mineralisation extending north-east of the Oculto Whittle pit.
The hole ended in high-grade silver and gold mineralisation, with the last 1m interval grading 12.1g/t gold and 273.5g/t silver (from 253.0 to 254.0 meters). Additional drilling is planned to test the depth extent of this mineralised zone.

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.

Effective August 31, 2017. The resource estimate and supporting technical report are N.I. 43-101 compliant. Full details of the Mineral Resources are available in a Company news release dated March 2, 2018.

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.
