The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices. Refer to Technical Notes below for metallurgical recoveries assumed in the 2018 PEA study on Diablillos.
John Miniotis, President and CEO, commented, “Our Phase I drill program was a remarkable success. I would personally like to congratulate our entire exploration team for all their efforts and the tremendous results achieved. With all the drill results from our Phase I drill program now in hand, and our Phase II program well underway, we are currently working on preparing an updated mineral resource estimate and preliminary economic assessment (“PEA”), which are expected to be released in Q3/2021 and Q4/2021, respectively.
David O’Connor, Chief Geologist, commented, “We are excited by the new drill results received from hole DDH 21-019 which continue to demonstrate the extension of high-grade silver and gold mineralisation beyond the western end of the Tesoro Zone, adding to the oxide resources. In addition, the copper-gold mineralisation intersected in hole DDH 21-020 shows continuity of high-grade sulphide mineralisation beneath the oxide zone, which will be systematically tested with follow-up drilling over the coming months.”

Discussion of Drill Hole Results
Hole DDH 21-019 extends the Tesoro Zone to the southwest, while hole DDH 21-020 was drilled south of the Tesoro Zone to test the mineralised system at depth.
Hole DDH 21-019 intersected high-grade gold and silver mineralisation, with 63.0 metres of 159.6 g/t silver and 1.63 g/t gold from 118 to 181 metres, including 8.0 metres of 212.6 g/t silver and 7.72 g/t gold. This hole shows continuity of silver and gold rich mineralisation beyond the western end of the Tesoro Zone.
Hole DDH 21-020 tested the southern edge of the mineralised zone as well as the underlying sulphide root zone. The hole intersected 19.5 metres of 148.9 g/t silver and 0.21g/t gold from 149.5 to 169 metres. In addition, results from the sulphide zone intersected 20.0 metres of 27.4 g/t silver, 1.45 g/t gold and 1.89% copper from 317.5 to 322.5 metres, including 5.0 metres of 39.2 g/t silver, 4.46 g/t gold and 2.54% copper.
Hole DDH 21-020 demonstrates continuity of the high-grade copper-gold mineralisation underlying the oxide resources in the sulphide zone, which will be systematically explored over the coming months.

Exploration Program Update
Phase I drilling: The Company’s 15,000-meter Phase I drilling was completed in April, and all results from the laboratory have now been received and announced. The results from the Phase I program comprised several world-class intercepts including:
- DDH 20-027: 103 m of 388.6 g/t silver and 1.70 g/t gold within oxides (from 141 to 244 m)
Including 17 m of 1,466.7 g/t silver and 0.55 g/t gold within oxides (from 163 to 180 m)
- DDH 21-012: 104 m of 216.2 g/t silver and 2.21 g/t gold within oxides (from 134 to 238 m)
- DDH 20-009: 83 m of 289.4 g/t silver and 1.45 g/t gold within oxides (from 171 to 254 m)
- DDH 21-009: 75 m of 166.7 g/t silver and 2.24 g/t gold within oxides (from 208 to 283 m)
- DDH 20-001: 15 m of 658.0 g/t silver, 2.35 g/t gold and 5.10% copper within sulphides (from 275 to 290 m)
All of the drill results from the Phase I program will be incorporated into an updated resource estimate which is expected to be announced in Q3/2021. The Company’s total costs for the Phase I exploration program came in under the budget of US$4.5 million.
Phase II drilling: The Company has now completed approximately 4,000 metres (17 holes) as part of its Phase 2 drill program, which will consist of a minimum of 10,000-metres of diamond drilling. There are currently two drill rigs operating at site, testing the continuity of gold mineralisation at the Oculto zone to the northeast in support of an expansion of the Whittle Pit boundary, and other targets peripheral to the Oculto zone. Systematic deeper drilling to test the underlying sulphide mineralisation is planned as a follow-up to additional exploration for oxide resources. The budget for the Phase II exploration program is US$3.0 million, and the Company remains very well-funded to expand the program if warranted by results.

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: Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo del Sol (Argentina)

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.
