Auryn Identifies Multiple Copper-Gold Drill Targets at Sombrero
Vancouver, British Columbia – November 26, 2018 – Auryn Resources Inc. (TSX: AUG, NYSE
AMERICAN: AUG, “Auryn” or the “Company”) has identified several kilometer-scale targets under
copper – gold surface mineralization at its Sombrero project in Southern Peru . The targets identified
tend to begin at surface and can continue to a depth of 600 meters, representing more than one
substantial opportunity for skarn and porphyry mineralization.
Ivan Bebek, Executive Chairman and Director:
“The Sombrero project continues to evolve as a globally significant exploration opportunity due to it ’s
scale and analogous features to the world-class mines nearby.
“It is a rare opportunity to explore a project with this size and scale that has never been drilled before.
We still don’t know the full extent of the mineralized system, on surface or at depth however, we
anticipate drill permits in the second quarter of 2019.”
The Targets:
The targets are based on extensive geological mapping, geochemical sampling and geophysical
surveys. The results of the targeting have outlined a large copper – gold system that is exposed over a
10 x 5 kilometer area (Figure 1). This scale of alteration and mineralization is similar in scale to the Las
Bambas complex and demonstrates the potential magnitude of the opportunity at the Sombrero project
(Figure 1). Auryn has recognized three superimposed separate target types within the observed
Sombrero mineralized system:
• Exoskarn high -grade gold: copper – gold targets located along the boundary between
monzonitic to dioritic intrusives and the Ferrobamba limestone.
• Endoskarn bulk tonnage : copper – gold targets hosted within the monzonitic to dioritic
intrusive rocks
• Porphyry bulk tonnage: copper – gold targets that are spatially associated with monzonitic
intrusive dykes and plugs.
The area currently being drill permitted (Figure 1) allows for 40 drill pads, giving Auryn’s technical
team flexibility in the initial program to make adjustments based on the geology identified while drilling.
There are a total of 7 high-priority exoskarn targets over a 4.5 kilometer strike length at the contact
between the multiphase intrusive complex and the Ferrobamba limestone (Figure 2). In addition, there
are a total of 6 high-priority chargeability (IP) targets over a 7.25 kilometer strike length that
represent the potential for bulk tonnage endoskarn and porphyry-styles of disseminated copper – gold
mineralization. Typically, these chargeability anomalies are situated between 100 – 150 meters below
the surface, with several of them situated underneath mineralized trenches. The 2019 drill program will
test for exoskarn targets, endoskarn targets and porphyry-style targets (Figure 3) with drill holes ranging
from 200 – 800 meters in depth.

Figure 1:
Figure 1 illustrates a size comparison of the mineralized system identified at the Sombrero project and the Las Bambas
cluster of deposits. The Sombrero project has three separate mineralized clusters identified to date at the Sombrero,
Nioc and Good Lucky occurrences, which appear over an area of approximately 10 x 5 kilometers, which is similar in
scale to the Las Bambas deposits.
Technical Rationale:
Geologic and Geochemical Summary:
The defined targets are centered around three exposed copper – gold systems at the Sombrero Main,
Nioc and Good Lucky areas, which are situated within a larger Pb-Zn mineralization alteration halo (15
x 10 kilometers) (Figure 4) that defines the known extent of the mineralization and alteration within the
project area. There are three recognized stages of mineralization present within the area, which are
defined below:
• Stage 1: Prograde exoskarn and endoskarn development associated with the emplacement of
large diorite bodies into the Ferrobamba and Gramadal limestone sequences. As part of this
event fracture network copper – gold mineralization is observed within the underlying sediments
within the Hualhuani and Labra Formations (Figure 3).
LEGAL_29515744.3
• Stage 2: Retrograde gold – copper breccias and vein development overprinting both calcsilicate
alteration within the endoskarn mineralization as well as the marble/wollastinite alteration within
the Ferrobamba limestone (Figure 3).
• Stage 3: Porphyry staged copper – gold veins and breccias associated with intense clay
alteration and the emplacement of evolved monzonitic intrusive dykes and plugs. These
evolved porphyry staged dykes and plugs are associated with a molybdenum geochemical
signature (Figure 4). These porphyry targets are developed both within the larger diorite
intrusive bodies as well as within the sediments of the Hualhuani and Labra Formations (Figure
3).
Figure 2:
Figure 2 illustrates the targets that form the basis for the initial 2019 drill program on the Sombrero property.
The image on the left defines the targets based on chargeability values above 25 millivolts, which represent
the potential for disseminated copper – gold mineralization and can be hosted in both endoskarn and porphyry-
styles of mineralization. There are a total of 6 chargeability anomalies that will be drilled, which represent 7.25
kilometers of strike length. The image on the right defines targets base d on magnetic intensity, which
represent the potential for high-grade exoskarn targets. There is a total of 7 magnetic anomalies that will be
drilled, which represent 4.5 kilometers of strike length.

Figure 3 illustrates drill traces depicted by the green lines on geological and geophysical cross-sections. These sections
demonstrate the drill targeting concepts that aim to build a discovery through drilling high -grade exoskarn and bulk
tonnage endoskarn and porphyry-styles of mineralization.
▪ Drill holes PDDH1, PDDH5, PDDH6 and PDDH10 target high-grade exoskarn mineralization at the contact
between the monzonitic intrusive and the Ferrobamba limestone.
▪ Drill hole PDDH2 targets bulk tonnage endoskarn mineralizati on in the monzonitic intrusive and then into
pophryry-style mineralization within the Hualhuani sediments through a chargeability anomaly of greater
than 25 millivolts.
▪ Drill holes PDDH3, PDDH4, PDDH6, PDDH7, PDDH8 and PDDH9 target bulk tonnage endoskarn a nd
porphyry mineralization hosted within monzonitic intrusives through chargeability anomalies greater than
25 millivolts.
Geophysics Summary:
The use of geophysics data has proven integral to the development of targets at the Sombrero project.
Through the integration of geologic mapping and magnetic and induced polarization data , Auryn has
been able to identify all of the target types listed above.
LEGAL_29515744.3
Magnetics Data:
Magnetic highs have a direct spatial correlation with mapped exoskarn bodies which allows us to target,
under the volcanic cover, the exoskarn that flanks the large multiphase intrusive body at the Sombrero
and Nioc targets (Figure 2). A total of 4.5 kilometers of strike length of exoskarn targets have been
defined along the flanks of the multiphase intrusive center, defining the Sombrero target and again
demonstrating the potential size of the mineralized system at the project.
Induced Polarization (IP) Data:
A comprehensive IP geophysical survey was completed in an effort to image disseminated sulphide
bodies defined by chargeability highs above 25 millivolts. These chargeability highs are interpreted to
have the potential to host significant copper – gold mineralization (Figure 2).
Figure 3 illustrates two cross-sections through the Sombrero target area that demonstrate the
distribution of exoskarn and endoskarn target types being observed on the surface and at depth
through the use of magnetics and IP geophysical surveys. These cross-sections integrate geological
mapping, surficial geochemical data from soils, rocks and trenches as well as the geophysical data.
Critically, all data sets support the potential for a large-scale copper – gold mineralized system, both
in skarn and porphyry -styles of mineralization , hosted within the Ferrobamba limestone, the multi -
phase intrusive complex and the Hualhuani sediments.
District-Scale Opportunity:
The drill targeting exercise has been completed over the Sombrero and Nioc target areas , an area of
approximately 5 x 5 kilometers. To date, work in the Sombrero district has focused on the Sombrero
North licences, which includes 62,000 hectares. Auryn controls an additional 58,000 hectares in the
Sombrero South project area, which is situated approximately 50-75 kilometers to the southeast of the
Sombrero North project area (Figure 5). Initial follow-up work on these anomalous dr ainage basins
has included higher resolution stream sediment surveys, reconnaissance mapping and rock sampling.
The goal of this work is to identify the next mineralized system to advance toward s drill targeting.
Results from this work are anticipated to be released over the next several months as Auryn continues
to develop new targets within the district.
Michael Henrichsen, C.O.O. and Chief Geologist:
“The drill targeting process has demonstrated that the Sombrero project has the scale, continuity of
mineralization on surface and required geophysical signatures to deliver a major copper – gold
discovery.
“We are very impressed with the geologic similarities between Sombrero and Las Bambas and are
looking forward to drilling the three target types of high-grade exoskarns, bulk tonnage endoskarns and
porphyry-styles of mineralization.”

Figure 4:
Figure 4 illustrates the geochemical zonation patterns within the Sombrero mineralized system. The system is defined
by a lead – zinc halo that occurs over an area of approximately 15 x 10 kilometers. Internal to this halo there are three
copper – gold systems that are exposed at the Sombrero, Nioc and Good Lucky occurrences. Molybdenum geochemical
signatures are typically located internal to the copper – gold systems and are spatially associated with evolved
monzonitic intrusive rocks that are associate d with porphyry-styles of mineralization. The image on the left shows the
mineralized system on a geologic map with the volcanic cover that is present; whereas, the image on the right shows
the same mineralized system on an interpreted geologic map with the volcanic cover removed.
