Auryn Identifies Significant Copper Mineralization at New Prospect Near Sombrero
Figure 1 illustrates the position of the Milpoc license located 12 kilometers to the south of the Sombrero Main target area. The license is characterized as an erosional window through volcanic cover with high-grade stratiform copper-oxide mineralization with porous sandstone units within the Casapalca formation. The two stars within the license area represent the mineralized areas.
Figure 2 illustrates the distribution of both copper-oxide and silver mineralization within the Milpoc licences. Stratiform mineralization occurs over an area approximately 1.2 kilometers by 500 meters and is primarily located within highly porous sandstone units within the Casapalca formation, which is situated above the Ferrobamba limestone. The cross-section at the bottom of the figure illustrates a conceptual model for the mineralization where a buried intrusive body would represent the source area for the mineralization observed on surface.

Vancouver, British Columbia – January 7, 2019 – Auryn Resources Inc. (TSX: AUG, NYSE AMERICAN: AUG, “Auryn” or the “Company”) has identified a significant zone of oxide copper mineralization over a 1.2-kilometer strike length and 500-meter width. It is located about 12 kilometers south of Sombrero at the Milpoc prospect (Figure 1). Rock samples have returned copper – oxide mineralization grades ranging from 0.1% – 8.45% and silver grades ranging from 0.06 g/t - 101 g/t (Table 1).
The stratiform mineralization identified at Milpoc is hosted within red bed sediments of the Casapalca formation and is the first mineralization observed stratigraphically above the Ferrobamba formation. The Ferrobamba hosts the known high-grade copper – gold exo-skarn mineralization at the Sombrero project to the north. This mineralization is preferentially hosted in highly porous sandstone units that typically have a thickness of 10 – 30 centimeters and there are numerous mineralized beds that occur over a 100-meter thickness within the sedimentary sequence.
In addition, the Ferrobamba limestone observed adjacent to the Casapalca formation is characterized by jasperoid silica bodies that are consistent with a distal signature to an intrusive or underlying skarn body at depth (Figure 2). Auryn will continue to evaluate the Milpoc prospect through magnetic surveying in an effort to identify the potential source area of the mineralization.
A Message from Michael Henrichsen, C.O.O. and Chief Geologist:
“The high-grade copper-oxide and silver mineralization at Milpoc represents another opportunity within the Sombrero district to discover an additional intrusive center that could be related to skarn and porphyry mineralization. Our technical group continues to discover new styles of mineralization in different formations that we feel demonstrate a very high level of mineral endowment within this newly-emerging district.”

* Approximately 2-3kg of material was collected for analysis and sent to ALS Lab in Lima, Peru for preparation and analysis. All samples are assayed using 30g nominal weight fire assay with ICP finish (Au-ICP21) and multi-element four acid digest ICP-AES/ICP-MS method (ME-MS61). Where ICP21 results were > 3 g/t Au the assays were repeated with 30g nominal weight fire assay with gravimetric finish (Au-GRA21). Where MS61 results were greater or near 10000 ppm Cu, 10000ppm Pb or 100ppm Ag the assays were repeated with ore grade four acid digest method (Cu-OG62). QA/QC programs for 2018 rock samples using lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed. These samples were collected in a non-representative manner. The mineralization may not be reflective of the underlying system. | ||

About Auryn
Auryn Resources is a technically driven junior mining exploration company focused on delivering shareholder value through project acquisition and development. The Company’s management team is highly experienced with an impressive track record of success and has assembled an extensive technical team as well as a premier gold exploration portfolio. Auryn is focused on scalable high-grade gold deposits in established mining jurisdictions, which include the Committee Bay and Gibson MacQuoid gold projects located in Nunavut, the Homestake Ridge gold project in British Columbia and a portfolio of gold projects in southern Peru, through Corisur Peru SAC.
About Sombrero
This project consists of the North Sombrero and South Sombrero properties, comprising approximately 100,000 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.
