Builds on Highly Successful Phase I Drill Program
Toronto - April 01, 2021: AbraSilver Resource Corp. (TSX.V:ABRA; OTCPK: ABBRF) ("AbraSilver" or the “Company”) is pleased to announce plans to continue the successful exploration program on its wholly owned Diablillos property, located in the mining-friendly Salta Province of Argentina. The Phase II drill program will consist of approximately 10,000 metres of diamond drilling designed to expand the existing mineral resources and will commence immediately following the conclusion of the Company's Phase I, 13,000-metre drilling program, which remains on-track to be completed by the middle of April 2021.
The Phase II drill program will focus on the following priority targets (see Figure 1):
John Miniotis, President and CEO, commented, “Our Phase I drill program, which was aimed at expanding the existing large resource base at Oculto has already been a tremendous success, with plenty more results yet to come. As a next step, we’re very excited to focus on the potential to explore several additional silver and gold target areas by taking a much broader perspective on the Diablillos land package as a whole”.
David O’Connor, Chief Geologist, commented, “Having completed sufficient drilling at Oculto which we believe will result in a considerably expanded resource for the proposed new PEA study, we are very pleased to commence the next phase of exploration drilling. Previous drilling has indicated exciting targets where we are hopeful to develop oxide gold dominant resources to augment the Oculto resource base. The Cerro Viejo porphyry copper-gold target is conceptual, but based on encouraging results of previous exploration. Successful drilling of this target could lead to a significant new discovery”.

Discussion of Phase I Drill Program and Updated PEA Study
The existing Phase I, 13,000-metre drill program remains on track to be completed by the middle of April. Due to the very encouraging silver and gold intercepts announced on March 15, 2021, including DDH 20-026 (65m @ 150.56g/t Ag and 1.88g/t Au) and DDH 20-027 (103m @ 388.62g/t Ag and 1.70g/t Au) the Company plans to drill the final five holes of the Phase I program in this area, which is at the intersection of major mineralized breccia zones, in order to better define this high-grade zone. Holes DDH 20-026 and DDH 20-027 are 125 meters apart, and three holes will be drilled between them, with one each beyond these holes at either end.
Once all assay results are received from the Phase I drilling program, the Company will publish an updated resource estimate, which remains on-track to be completed in mid-2021.
Following the updated resource estimate, the Company plans to deliver an updated Preliminary Economic Assessment (“PEA”) study, which is expected to demonstrate that Diablillos is a very high-margin, economically robust silver-gold project based on results from the 2018 PEA and work done since that time. The updated PEA will be based on the updated resource model, all metallurgical testwork and is expected to be completed in the second half of 2021.
Phase II Exploration Program Targets
The additional 10,000-metre Phase II drill program, will continue with two diamond drill rigs and is expected to be completed by July 2021. This program and the number of drill rigs may be expanded if warranted. The main exploration targets in the Phase II program are summarized below.
Oculto Northeast Extension:
Previous drilling intersected significant gold values northeast of the Whittle Pit (see Figure 2), including:
Significant gold values extend more than 500 metres outside the existing Whittle Pit boundary and into the Zorro and Cerro Bayo areas where siliceous breccia zones outcrop. Drilling will be aimed at expanding the resource base to support a larger pit and potential associated deeper resources potentially mineable from underground.

Laderas Zone:
Gold and silver mineralization at Laderas occurs within structurally controlled, highly weathered, siliceous hydrothermal breccias hosted in Tertiary sedimentary and volcanic rocks similar to Oculto. Controlling structures are steeply dipping and strike in a wide range of orientations including east-northeast, northeast, northwest, west-northwest, and west (Figure 3). The mineralized zones are accompanied by silica-alunite alteration which rapidly grades outwards to alunite at the walls of the breccias.
Previous drilling obtained the following shallow intercepts:

Northern Arc Targets:
This group of prospects lies approximately 3 to 4 kilometres north-northeast of the centre of the Oculto deposit. Each of the Northern Arc prospects has epithermal silver-gold targets similar in style to Oculto, and Cerro Viejo shows potential for porphyry mineralization.
The Pedernales prospect contains the following intercept:
At the Corderos prospect there is excellent breccia development and strong silica alteration exposed at surface. Drilling has demonstrated very high gold grades near surface, including:
At Cerro Viejo Oeste there is a very large area of crackle breccia, with some internal hydrothermal breccias. This is considered a possible porphyry target, with a siliceous carapace hosting anomalous gold. A deep hole is planned to explore for porphyry copper-gold mineralisation at Cerro Viejo Oeste.

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.
