AbraSilver Announces Additional High-Grade Drill Results in the Oculto Northeast Zone; Near-Surface Intercepts Include 43.5 Metres Grading 196 g/t AgEq (2.8 g/t AuEq)
Near-Surface, Intercept Includes Bonanza Silver Grades of 1,423 g/t AgEq (20.3 g/t AuEq) over 4m
Toronto – August 11, 2022: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is pleased to announce assay results from three new diamond drill holes from the Phase II drill program located on the Company’s wholly owned Diablillos property in Salta Province, Argentina.
All three holes were located in the Oculto Northeast zone. Key takeaways include:
- DDH 22-021 intersected a near-surface, high-grade silver interval of 17m at 365 g/t AgEq (5.2 g/t AuEq - comprised of 355 g/t Ag and 0.14 g/t Au) in oxides starting at a down-hole depth of only 53 metres. This included a bonanza-grade 5m interval of 1,037 g/t AgEq (14.8 g/t AuEq – comprised of 1,022 g/t Ag & 0.21 g/t Au);
- DDH 22-022 intersected multiple zones of high-grade gold mineralization, including a broad intercept of 34m at 156 g/t AgEq (2.2 g/t AuEq - comprised of 18 g/t Ag and 1.98 g/t Au);
- DDH 22-024 intersected near-surface, high-grade silver mineralization including a broad intercept of 43.5m grading 196 g/t AgEq (2.8 g/t AuEq - comprised of 188 g/t Ag and 0.11 g/t Au) in oxides starting at a down-hole depth of only 68.5 metres. The hole included a bonanza-grade interval of 4m at 1,423 g/t AgEq (20.3 g/t AuEq – comprised of 1,410 g/t Ag & 0.18 g/t Au);
John Miniotis, President and CEO, commented, “We are very encouraged by the numerous near-surface, high-grade silver results intersected in the Northeast zone by these latest drill holes, as well as the underlying high-grade gold intercepts. These results will be included in the updated Mineral Resource estimate which will be announced later this year. It is evident that the multiple zones of mineralisation being encountered in the Northeast zone should add substantially to our overall Mineral Resource estimate which continues to grow rapidly.”
Dave O’Connor, Chief Geologist, commented, “These new results, drilled in the Oculto Northeast zone, help clearly demonstrate the continuity of numerous mineralized breccia zones in this highly prospective area. What is particularly encouraging is the newly discovered shallow, high-grade silver mineralization encountered in holes 21 and 24, which is expected to allow for a substantial expansion of the conceptual open pit towards the northeast.
Furthermore, these latest intercepts are located over 1km along strike from the newly discovered Southwest zone, announced on August 3rd, highlighting that we are successfully expanding high-grade mineralisation in both directions beyond the current Oculto Mineral Resource and along multiple breccia zones.”
The latest assay result highlights are summarized in Table 1 below.

1AgEq & AuEq calculations for reported drill results are based on USD $1,750/oz, $25.00/oz Ag & $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 22-021 intersected numerous zones of high-grade oxide mineralisation, commencing with a near-surface, high-grade silver zone consisting of 17 metres grading 355 g/t Ag and 0.14 g/t Au starting from a down hole depth of only 53 metres. The hole was stopped in sulphide mineralization and encountered a high-grade copper and gold interval of 67 g/t Ag, 1.26 g/t Au and 2.49% Cu over 1 metre, at a down-hole depth of 305 metres.
Hole DDH 22-022 was drilled outside of the proposed open pit shell and successfully intersected multiple zones of high-grade gold mineralization. The highlight intercept consisted of 34 metres grading 18 g/t Ag and 1.98 g/t Au, including 10 metres of 26 g/t AG and 3.39 g/t Au. The hole was terminated when it reached sulphide mineralization, with high-grade copper and gold intercepts, consisting of 2 metres at 24 g/t Ag, 3.72 g/t Au and 0.61% Cu, and an additional 2 metres grading 8 g/t Ag, 0.79 g/t Au and 1.22% Cu.
Hole DDH 22-024 intersected multiple zones of high-grade silver and gold mineralization, including 43.5 metres grading 188 g/t Ag and 0.11 g/t Au, starting from a down hole depth of only 68.5 metres. The hole intersected numerous broad zones of high-grade mineralization which is expected to help further expand the Mineral Resources in this area.
Mineralisation in the Northeast zone is controlled by several structures hosting siliceous breccias, including the North Breccia Zone, the West Breccia Zone and the Main breccia Zone, see Figure 1 below. These mineralised zones are open towards the northeast where historical drilling indicates that they have considerable strike extent. The structures are particularly well mineralised where the breccias coalesce and these areas represent our main drill targets for higher grade mineralization. The newly discovered shallow silver zone also represents a prime exploration target as this is expected to allow for an expansion of the conceptual open pit.

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 100,000 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 2 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.
