AbraSilver Announces Final Phase II Drill Results at Diablillos Including 38.5 Metres at 183 g/t AgEq (2.6 g/t AuEq)

Toronto – September 15, 2022: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is pleased to announce assay results from the final eight diamond drill holes completed as part of the Company’s highly-successful Phase II drill program, on its wholly-owned Diablillos property in Salta Province, Argentina.

The latest batch of holes targeted the Northeast zone, as well as the extension potential of the conceptual Oculto open pit.   Key takeaways include:

  • Hole DDH 22-041 intersected 38.5 metres at 183 g/t AgEq (2.6 g/t AuEq – comprised of 119 g/t Ag and 0.91 g/t Au) in oxides starting at a down-hole depth of only 74 metres. The hole included a 12.5 metre interval grading 350 g/t AgEq (5.00 g/t AuEq).
  • Well-mineralized oxide intercepts were encountered in all of the final 8 holes from the Phase II program.  All results will be incorporated into an updated Mineral Resource estimate to be released next month.

The latest assay result highlights are summarized in Table 1 and Table 2 below.

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 and $25.00/oz Ag. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices.

John Miniotis, President and CEO, commented, “We are very pleased with the excellent results received from our 20,000 metre Phase II drill program. The drill program successfully demonstrated the robust exploration upside potential at Diablillos, where we have not yet reached the limit of the strike and depth continuity of several mineralized zones.  We’re looking forward to announcing our updated Mineral Resource estimate in October, and continuing to add value from our exciting Phase III exploration program which is currently drilling in the Southwest zone, where hole DDH 22-019 recently intersected 87 meters of 346 g/t Ag near-surface.”

Dave O’Connor, Chief Geologist, commented, “These latest drill results add to our knowledge of the structures controlling mineralisation in the Northeast zone beyond the conceptual Oculto open pit, demonstrating the excellent continuity of numerous mineralized breccia zones in this area. With all the drill results from our Phase II drill program now in hand, the Company’s near-term exploration focus is on the newly discovered Southwest zone, which displays significant potential for future growth of Mineral Resources and a significantly expanded open pit”  

Figure 1 – Oculto Plan View of Drill Results 

Figure 2 below highlights the Oculto mineralised system which is now known to extend well beyond the conceptual open pit and is open for at least two kilometres along strike. Drilling is continuing both to the northeast and southwest as well as laterally, demonstrating increasing tonnage potential of the system.

Discussion of Drill Hole Results

The latest drill intercepts were focused primarily northeast of the open pit where several mineralized breccia structures extend well beyond the conceptual Oculto open pit boundary. These results demonstrate continuity of mineralization in this area and continue to confirm the strong potential to expand the current Mineral Resource base outside of the current conceptual open pit shell.

Hole DDH 22-032 intersected several well-mineralized zones throughout the hole, including 44 metres at 35 g/t Ag and 1.38 g/t Au in oxides from a downhole depth of 165.5 metres. The same hole, also encountered an interval of 46 metres at 18.5 g/t Ag and 1.73 g/t Au deeper down in the oxide/sulphide transition zone.  These intervals were located outside of the current conceptual open pit margins, demonstrating potential for an expansion of the open pit towards the northeast.

Hole DDH 22-041 was an in-fill hole drilled within the conceptual open pit boundary to test the northeast extension of the West Breccia zone. The hole successfully encountered a near-surface intercept of 38.5 metres at 119 g/t Ag and 0.91 g/t Au in oxides from a downhole depth of 74 metres.

In the Northeast Zone, hole DDH 22-031 was located approximately 350 metres beyond the current open pit boundary, and successfully intercepted a high-grade gold intercept of 3.25 g/t Au and 33 g/t Ag over 20 metres.  These results, combined with prior drilling in the Northeast Zone, demonstrate the large size of the system which extends for at least 500 metres beyond the conceptual open pit margin.

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 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 3:

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.
