Record High Oxide Intercept Includes 9,536 g/t AgEq (136.2 g/t AuEq) over 4 Metres
Toronto – July 25, 2022: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is very pleased to announce assay results from its latest diamond drill holes from the Phase II program on the Company’s wholly-owned Diablillos property in Salta Province, Argentina (“Diablillos” or the “Project”).
Diamond drill hole DDH 22-015 contains the highest-grade silver intercept recorded on the Project to date. Key takeaways from the latest intercept includes:
- Hole DDH 22-015 was drilled to test the southwestern extension of the high-grade Tesoro Zone. The highest-grade intersection consisted of 26 metres at 2,383 g/t AgEq (34.0 g/t AuEq - comprised of 2,358 g/t Ag and 0.36 g/t Au), including 4 metres at 9,536 g/t AgEq (136.2 g/t AuEq – comprised of 9,488 g/t Ag and 0.69 g/t Au); and
- This drill hole further extends the high-grade Tesoro zone by an additional 25 metres towards the west, thereby extending the dimensions of this zone to over 500m in length by approximately 100m width
John Miniotis, President and CEO, commented, “Without a doubt, assay results from our Phase II drill campaign continue to exceed all expectations. This exceptional high-grade drill result meaningfully extends the Tesoro zone and adds to a series of outstanding drill intersections recently announced, which are expected to have a positive impact on the forthcoming Mineral Resource Estimate update and Pre-Feasibility Study (PFS) for the Diablillos project.”
The latest assay result highlights are summarized in Table 1 and Table 2 below. These drill holes will form part of the inputs to the updated Mineral Resource Estimate expected to be announced later this year.

Dave O’Connor, Chief Geologist, commented, “We are very excited that drill hole DDH 22-015 returned the highest-grade silver intercept ever recorded at Diablillos, an impressive result with over 125,000 metres drilled on the Project to date. This result confirms that the high-grade Tesoro zone is open and can be expanded, which should provide a significant boost to the overall economics of the Project. Looking ahead, we continue to await further drill results from our Phase II program, including important step-out drill holes in the new emerging southwest zone.”

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.
1AgEq & AuEq calculations for reported drill results are based on USD $1,750/oz, $25.00/oz Ag 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.

Discussion of Drill Hole Results
Hole DDH 22-015 was drilled to test the southwestern extension of the Tesoro Zone. The record high-grade intercept consisted of 26 metres at 2,358 g/t Ag and 0.36 g/t Au in oxides from 131.5 to 157.5 metres, including 4 metres at 9,488 g/t Ag and 0.69 g/t Au starting at 148.5 metres downhole. The high-grade intercept in the Tesoro Zone is expected to substantially increase both the tonnage and silver grades of the existing Mineral Resources classified in the Measured category and could have a marked positive effect on the project economics. Additional drill holes are planned to test the continuity of this high-grade zone farther to the southwest in the Phase III program.
Hole DDH 22-006 was an in-fill drill hole which obtained multiple intersects in the oxide zone, including 26 metres at 67 g/t Ag and 1.67 g/t Au from 107 to 133 metres. The hole also obtained high-grade gold intercepts in oxides with 15 metres at 3.17 g/t AuEq, including a very high-grade interval of 1 metre grading 23.37 g/t AuEq.
Hole DDH 22-007 was a step-out hole drilled well northeast of the proposed open pit and intersected numerous narrower zones of mineralization including 3 metres at 4.91 g/t AuEq in the deeper gold zone.
Hole DDH 22-008 was a reconnaissance hole drilled east of Oculto. The hole intersected deep mineralization in the oxide zone including 26 metres at 44 g/t Ag and 0.45 g/t Au.
Hole DDH 22-013 was drilled in the southwest extension of the shallow gold zone and intersected narrow zones of gold dominant mineralisation.

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 over 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).
The most recent Mineral Resource Estimate for the Oculto Deposit is shown in Table 3 below:

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.
