AbraPlata Continues to Intersect High Grade, Near-Surface Oxide Silver & Gold Mineralisation Including 13.5 Metres Grading 515 g/t AgEq (6.86 g/t AuEq) at Diablillos
Toronto - February 03, 2021: AbraPlata Resource Corp. (TSX.V:ABRA; OTCPK: ABBRF) ("AbraPlata" or the “Company”) is pleased to announce the latest assays received for five diamond drill holes on its wholly-owned Diablillos property in Salta Province, Argentina.
Four of the drill holes were designed to develop shallow resources within the Whittle Pit area at Oculto. Holes DDH 20-018 and DDH 20-020 were short holes drilled to a depth of only 50 meters from the same platform to test for near-surface gold mineralisation. Both holes intersected significant gold and silver mineralization near surface, including 13.5 metres grading 515 g/t silver equivalent (“AgEq”) starting from 3 metres downhole in hole DDH-20-020. These previously undefined shallow resources within the Whittle Pit will contribute significantly to the early economics of open pit mining.
In addition, a reconnaissance hole in the Laderas zone, intersected 24 meters grading 1.49% copper with 34.79 g/t silver and 0.22 g/t gold approximately 500 meters north of the Oculto resource. Hole DDH 20-019 was drilled to a total depth of 244.5 meters and intersected substantial copper sulphide mineralisation with associated silver and gold. Large linear outcrops of siliceous breccia that occur in the Laderas area suggest that the copper and associated precious metal mineralisation intersected in hole DDH 20-019 may be extensive. As a result, follow-up drilling is now being planned at Laderas.
Table 1 – Drill Result Highlights:
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.
John Miniotis, President & CEO, commented, “We are very pleased with the positive drill results that are being consistently encountered at our Diablillos silver-gold project. We are looking forward to a busy year ahead, in which AbraPlata remains fully funded with a very strong balance sheet in hand, enabling us to continue to aggressively explore and advance the project. Against a backdrop of favourable silver and gold prices, we are confident that we will continue to build on our exploration successes and add significant value for our shareholders."

Multiple Shallow Holes with Near-Surface Mineralisation
All four shallow holes drilled (DDH 20-005, DDH 20-018, DDH 20-020 and DDH 20-024) showed very good continuity of near-surface mineralisation within the Whittle Pit boundary. Systematic drilling of this previously undefined shallow mineralisation continues and further results will be released as they become available.
Hole 20-005 was drilled on section 8175 and is located towards the south-west. The hole intercepted a near-surface zone of shallow gold and silver mineralisation which is not reflected in the current resource estimate.

Holes DDH 20-018 and DDH 20-020 were 50-meter holes drilled to test for shallow gold and silver mineralisation within the Whittle pit. Hole DDH 20-018 intersected 16.5 meters grading 1.11 g/t gold 114 g/t silver, while hole DDH 20-020 intersected 21 meters grading 2.93 g/t gold & 132 g/t silver, displaying excellent continuity of high-grade zones of shallow gold and silver mineralization.

Hole DDH 20-024 was a shallow hole drilled to test for near-surface gold mineralisation. It was stopped in silver mineralisation at a depth of 110m because previous drilling had tested the main underlying silver zone at this locality. Hole DDH 20-024 intersected several zones of shallow mineralisation including 4 meters grading 3.25 g/t gold and 96 g/t silver.

Holes DDH 20-019 – Step-Out Hole at Laderas Zone
At the Laderas zone, gold and silver mineralisation, with associated copper, occur in hydrothermal breccias in volcanic rocks similar to Oculto. There is currently no mineral resource estimate for the Laderas zone and most of the historic drilling in this area has been shallow.
Hole DDH 20-019 was drilled to the north of Oculto into the Laderas zone where previous drilling obtained interesting mineralisation associated with a zone of outcropping silica breccias. Hole DDH 20-019 intersected 10.5 meters grading 1.48% copper, 0.35g/t gold and 34.02g/t silver in sulphides approximately 500 metres north of the Oculto mineralized zone. This encouraging mineralisation will be followed up with additional drilling.

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.
