Auryn Trenches 184 meters of 0.57% Copper-Gold Equivalent at Sombrero

Auryn Resources Inc announced results from the first trench at the Fierrazo area at the Sombrero copper-gold project in southern Peru. Trench 20 is characterized by a continuous broad interval of both endoskarn and exoskarn mineralization that sampled 184 meters of 0.57% copper equivalent, including threehigher grade internal intervals of 20 meters of 1.53% copper equivalent (1.50% copper and 0.04 g/t gold), 24 meters of 0.76% copper equivalent (0.70% copper and 0.09 g/t gold)and 20 meters of 0.95% copper equivalent.

A Message from Ivan Bebek, Executive Chairman & Director “This trench considerably increases our confidence that Sombrero could develop into a major copper-gold discovery. Trench 20 is the widest trench we have completed due to access to bedrock, and the grade is comparative to major mines along the Las Bambas belt nearby. We are very excited about additional trenches at Fierazzo, which are underway, and to begin surface work at the Nioc, Good Lucky and Totora targets. We anticipate a steady flow of trenching and sampling results in the months ahead prior to receiving our first drill permit at Sombrero Main.”

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.

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.

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.
