AbraSilver Announces Further World-Class Drill Results, Including New All-Time Best Silver Intercept at Diablillos of 127 Metres at 646 g/t AgEq (9.2 g/t AuEq)
Latest Results Returned Two of the Top Four Best Intercepts Ever Reported at Diablillos
Toronto – September 29, 2022: AbraSilver Resource Corp. (TSX.V: ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is very pleased to announce the first set of assay results from the Company’s ongoing Phase III drill program, on its wholly-owned Diablillos property in Salta Province, Argentina (the “Project”).
The first two holes returned two of the top four best silver-equivalent intercepts ever reported at Diablillos on a grade-thickness basis, including two separate bonanza-grade zones that intersected greater than 2,000 g/t AgEq over 23 metres each. Key takeaways include:
- Hole DDH 22-045 contains the new all-time highest-grade silver intercept recorded on the Project. In total, the hole returned 127 metres at 646 g/t AgEq (9.2 g/t AuEq – comprised of 506 g/t Ag and 1.99 g/t Au) in oxides starting at a down-hole depth of only 122 metres and included:
- Bonanza-grade silver mineralization grading 2,001 g/t AgEq (28.6 g/t AuEq) in oxides over an impressive 23 metre interval, starting at a down-hole depth of 152m.
- Hole DDH 22-043 intersected two separate high-grade zones. The first high-grade zone returned 154 metres at 144 g/t AgEq (2.1 g/t AuEq – comprised of 72 g/t Ag and 1.03 g/t Au) in oxides starting at a down-hole depth of only 36 metres.
- Deeper down, a bonanza-grade zone was intersected in sulphides consisting of 2,116 g/t AgEq (30.2 g/t AuEq) over 23 metres.
- Hole DDH 22-047 also encountered a high-grade intercept of 43 metres at 250 g/t AgEq (3.6 g/t AuEq - comprised of 135 g/t Ag and 1.65 g/t Au) in oxides starting at a down-hole depth of only 101 metres. The hole was located towards the Northeast limit of the conceptual open pit.
The latest assay result highlights are summarized in Table 1 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, $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.
John Miniotis, President and CEO, commented, “The spectacularly high-grade intercept of 646 g/t AgEq over 127 metres in hole 45, represents the best-ever drill result encountered on the Diablillos project. Moreover, today’s announcement includes a 23-metre interval of 2,116 g/t AgEq in hole DDH-22-043, which ranks as the fourth-best drill result in the Project’s history, on a grade-thickness basis. The Company’s ongoing exploration success and track record of outstanding drill results, are presently unparalleled across the silver industry, demonstrating the world-class upside potential of the Diablillos project.”
Dave O’Connor, Chief Geologist, commented, “We are delighted with the truly spectacular results received from the initial holes of our Phase III drill program which continue to demonstrate the extensive exploration potential at Diablillos, as well as the extremely high-grade nature of the Tesoro Zone. We are looking forward to additional high-grade silver and gold intercepts along the known two-kilometer length of this mineralized system, which continues to demonstrate remarkable upside potential.”

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 on testing the extension potential of the high-grade Tesoro zone, as well as in-fill drilling mineralization towards the northeast limit of the conceptual open pit.
Hole DDH 22-045 was drilled to test the southern extension of the Tesoro Zone. The new all-time high-grade record intercept consisted of 127 metres at 506 g/t Ag and 1.99 g/t Au in oxides from 122 to 249 metres. The interval encountered bonanza-grade silver mineralization grading 1,961 g/t Ag over 23 metres, as well as bonanza-grade gold mineralization grading 13.45 g/t Au over 6 metres in oxides.
Hole DDH 22-043 was drilled within the Tesoro Zone and intersected several well-mineralized zones throughout the hole. Starting from a down-hole depth of only 36 metres, the hole initially encountered 154 metres of 72 g/t Ag and 1.03 g/t Au in oxides. The same hole then encountered a subsequent interval of 23 metres at 1,939 g/t Ag, 0.28 g/t Au and 1.9% Cu, deeper down in sulphide mineralization.
Both holes, DDH 22-043 and DDH 22-045 are located near the high-grade Tesoro Zone. These new results are expected to continue to substantially increase both the tonnage and grades of the Mineral Resources classified in the Measured category and are expected to have a marked positive effect on the future economics of the project. Additional drill holes are planned to test the continuity of the high-grade Tesoro zone as part of the ongoing Phase III program.
Hole DDH 22-047 was an in-fill hole drilled within the conceptual open pit boundary to test the northeast extension of the Main Breccia zone. The hole successfully encountered a near-surface intercept of 43 metres at 135 g/t Ag and 1.65 g/t Au in oxides starting from a downhole depth of 101 metres.

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:

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, and he has reviewed and approved the scientific and technical information in this news release.
