Auryn Trenches 184 meters of 0.57% Copper-Gold Equivalent at Sombrero
Significance of Trench Results to the Sombrero Project:
The results from Trench 20, from the recently optioned Fierrazo concession (see press release from Dec 19, 2018), extend the known copper-gold skarn mineralization to over a 3.5-kilometer strike length along the margins of the contact zone between the Ferrobamba limestone and the mineralizing intrusive. The results from trenching programs to date provide a large-scale target where both high-grade exoskarn (109 meters of 0.70% copper equivalent in Trench 18 [3.5 km from Trench 20]) and bulk tonnage endoskarn mineralization (105 meters of 0.30% copper equivalent in Trench 09 [1.5 km from Trench 20]) have been encountered (Figure 2).
Trench 20 extends the copper-gold mineralization 1.5 kilometers to the northeast of previous results from Trench 09. The area between the mineralized trenches is obscured with post-mineralization volcanic cover, but based on the continuity of mineralization observed on surface and robust chargeability geophysical anomalies, Auryn believes the mineralized system continues beneath the cover.
Geologic Details at the Fierrazo License:
Importantly, a previously unrecognized block of Ferrobamba limestone has been encountered in the Fierrazo trenching program. It is dipping steeply to the west, indicating excellent depth potential from the mineralization encountered on surface at Trench 20. In addition, evolved monzonite porphyry dikes have been recognized, which demonstrates the potential for significant porphyry mineralization. A total of four additional trenches are currently in process at the Fierrazo license to better define the surface mineralization and the geometry of the Ferrobamba limestone, which coincides with a 750-meter by 250-meter copper-in-soils geochemical anomaly (Figure 3).
A Message from Michael Henrichsen, COO & Chief Geologist:
"We are very impressed with our first trench at the Fierrazo concession area. The long, continuous copper-gold results validate our exploration model and have given our technical team a great deal of confidence in the potential of the project to deliver a discovery drill hole in the first ever drill program at the project."
Sombrero Exploration Plans:
Auryn plans to expand its surficial exploration program, which includes soil sampling, rock sampling, trenching and geophysical surveys at the Nioc, Good Lucky and Totora target areas. These targets are characterized by strong skarn and porphyry styles of mineralization at surface (Figure 4). Drill targets will be developed at each of these mineralized intrusive centers with applications for drilling permits expected to be completed by the end of 2019.

Figure 2: Illustrates the position of Trench 20 relative to Auryn's previously announced trench results. In total, Auryn has now trenched significant copper-gold mineralization over 3.5 kilometers of strike length and has extended mineralization by 1.5 kilometers to the northeast with the results from Trench 20.

About Auryn
Auryn Resources is a technically-driven, well-financed junior exploration company focused on finding and advancing globally significant precious and base metal deposits. The company has a portfolio approach to asset acquisition and has seven projects, including two flagships: the Committee Bay high-grade gold project in Nunavut and the Sombrero copper-gold project in southern Peru. Auryn's technical and management teams have an impressive track record of successfully monetizing assets for all stakeholders and local communities in which it operates. Auryn conducts itself to the highest standards of corporate governance and sustainability.
About Sombrero
This project consists of the North Sombrero and South Sombrero properties, comprising over 120,000 hectares of mineral claims owned or optioned by Auryn Resources. The copper-gold Sombrero mining concessions are located 340 kilometers SE of Lima in southern Peru and are hosted in the Andahuaylas-Yauri belt. This belt is interpreted to be on the north-western margins of this Eocene-Oligocene aged copper-gold porphyry and skarn belt that hosts the Las Bambas, Haquira, Los Chancas, Cotambambas, Constancia, Antapaccay and Tintaya deposits. The project is characterized by a strong structural control and significant copper and gold values from historical surface samples. The principle targets at Sombrero are copper-gold skarn and porphyry systems and precious metal epithermal deposits.
Trenches 2019 (Sombrero, Peru)
Analytical samples were taken from each 2-meter interval of trench floor resulting in approximately 2-3kg of rock chips material per sample. Collected samples were sent to ALS Lab in Lima, Peru for preparation and analysis. All samples are assayed using 30g nominal weight fire assay with atomic absorption finish (Au-AA25) and multi-element four acid digest ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10,000 ppm Cu, Zn or Pb the assay was repeated with ore grade four acid digest method (OG62). QA/QC programs for 2019 trench grab samples using internal standard and blank samples; field and lab duplicates indicate good overall accuracy and precision.
Intervals were calculated using a minimum of a 0.1% Cu cut-off at beginning and end of the interval and allowing for no more than five consecutive meters of less than 0.1% Cu with a minimum length of the resulting composite of 5m.
Copper and gold equivalent grades (CuEq and AuEq) were calculated using gold price of $1300/oz and copper price of $3.00/lb.
