AbraPlata Reports Additional High-Grade Silver, Gold and Copper Mineralisation Including 83 Metres Grading 398 g/t AgEq (5.3 g/t AuEq) at Diablillos Project
Toronto - December 07, 2020: AbraPlata Resource Corp. (TSX.V:ABRA; OTCPK: ABBRF) ("AbraPlata" or the “Company”) is pleased to announce significant high-grade assay results from diamond drill hole DDH 20-009 completed at the Oculto deposit, located on its wholly-owned Diablillos in Salta Province, Argentina. The hole was designed to test extensions beyond the current mineral resource.
Hole DDH 20-009 intersected a broad zone of silver and gold mineralisation within the oxide horizon, as well as a substantial zone of gold mineralisation at the base of the oxides, beneath which there is a zone of gold mineralisation associated with copper sulphides. This extends our knowledge of the mineralised system at depth, beneath the Whittle Pit. Highlight intercepts are shown in Table 1 and include an 83 metre interval, starting from 171 m downhole, grading 289.4 g/t Ag and 1.45 g/t Au.
Partial results of hole DDH 20-008 were announced on October 26th, 2020 and complete results are now available. The hole was drilled south of the known mineralised system and obtained a silver intersection extending the zone in this direction, together with a gold zone associated with high-grade copper at depth.
Table 1 – Drill Result Highlights from DDH 20-008 and DDH 20-009:
|Drill Hole||From (m)||To (m)||Type||Interval (m)||Ag
|AgEq1 g/t||AuEq1 g/t|
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.
1 AgEq & AuEq calculations for reported drill results are based on USD $20.00/oz Ag, $1,500/oz Au 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. Refer to Technical Notes below for metallurgical recoveries assumed in the 2018 PEA study on Diablillos.
Dave O’Connor, Chief Geologist, commented, “We are extremely pleased with the results of hole DDH 20-009 which expands our knowledge of the deeper oxide gold zone that is associated with hydrothermal breccias developed along the basal unconformity of the andesite volcanics, as well as the underlying sulphide gold-copper mineralisation at Oculto.”

Hole DDH 20-009
The broad zone of high-grade silver and mineralisation in hole DDH 20-009 (83m @ 398 g/t AgEq) intersected between 171 and 254m depth significantly enhances the grade of oxide silver resource estimated within the Whittle Pit boundary, and also expands the resource beneath the base of the pit where it includes gold associated with copper sulphide mineralisation.

Exploration Program Update
To date, the Company has reported results from a total of 11 diamond drill holes in the Oculto Zone as part of its recently expanded exploration program. To date, the Company has completed drilling a total of 28 diamond drill holes and is awaiting results for the remaining holes. The priority drilling targets are:
- To continue to expand our knowledge of the deeper oxide gold zone;
- To add to the resource base north-east of the Whittle Pit boundary;
- To define a shallow gold zone (from surface to ~100m depth) which would benefit early open pit mining operations.
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: El Indio, Chile; Veladero, Argentina; and Pascua Lama, on the Chile-Argentine border.

QA/QC and Core Sampling Protocols
AbraPlata 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 AbraPlata, is the qualified person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects, has reviewed and approved the scientific and technical information in this news release.
All results in this news release are rounded. Assays are uncut and undiluted. Intervals are drilled widths, not true widths. AgEq calculations for reported drill results are based on USD $20.00/oz Ag, $1,500/oz Au 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. The most recent technical report for the Diablillos Project is the 2018 Preliminary Economic Assessment (PEA) authored by Roscoe Postle Associates Inc. The PEA assumes average metallurgical recoveries of 82% Ag and 86% Au. No metallurgical testwork has yet been completed on the recovery of copper.
