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.
David O’Connor, Chief Geologist, commented, “We are excited by the initial drill results received from the Phase II drill program which demonstrate the extension of substantial gold mineralisation for hundreds of metres beyond the Whittle Pit boundary in the Oculto Northeast Gold Zone. Together with the ongoing systematic drilling of the area, these holes continue to expand our knowledge of the Oculto mineralised system well beyond the limits of the current Whittle Pit margin and the resource estimate currently in progress. In addition, the underlying copper-gold mineralisation will be systematically tested with follow up drilling to develop an initial sulphide resource.”

Discussion of Drill Hole Results
Holes DDH 21-021, DDH 21-022 and DDH 21-023 were step-out holes drilled between 250 to 400 metres beyond the Whittle pit to explore for possible northeast extensions of mineralisation. All holes intersected significant gold mineralisation and systematic drilling continues in the Oculto northeast zone aimed at expanding the mineral resources beyond the Whittle Pit.
DDH 21-021 has various mineralised intervals including 20.5 metres of 2.82 g/t gold and 24.4 g/t silver from 182.0 to 202.5 metres, together with numerous narrow gold and silver intercepts within the oxide and underlying sulphide zone where mineralisation is associated with copper sulphides.
Hole DDH 21-022 intersected 53 metres of oxide mineralisation grading 2.49g/t gold and 33.3g/t silver from 192 to 245 metres, including 14 metres grading 4.84g/t Au and 47.2g/t Ag. The gold dominant mineralisation is hosted in a siliceous breccia zone to the north of and sub-parallel to those that intersect in the Tersoro Zone of the Oculto resource, demonstrating the potential for substantial extension of the mineralised system in this area.
Hole DDH 21-023 intersected numerous zones of gold and silver mineralisation with oxides down to 317 metres and mineralisation associated with copper in sulphides below that. These are considered to be the peripheral parts of a robust mineralised system which extends for at least half a kilometre to the northeast of Oculto where high grade gold mineralisation was intersected in previous drilling.
Systematic drilling is ongoing and aimed and continuing to extend the deposit's established mineralized zones in the Northeast Gold Zone. The target in Oculto Northeast is the gold dominant oxide mineralisation hosted in several structurally prepared zones which extend well beyond the margin of the current Whittle pit as demonstrated by recent mapping an trenching of surface siliceous breccia outcrops.

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 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. For additional information please see Technical Report on the Diablillos Project, Salta Province, Argentina, dated April 16, 2018, completed by Roscoe Postle Associates Inc, and available on www.SEDAR.com.
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.
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.
