Rockhaven Discovers Multiple New Mineralized Structures – Exploration Drilling
Cuts 10.12 m grading 1.16 g/t Gold and 18.7 g/t Silver at Klaza Project, Yukon
December 4, 2017 - Rockhaven Resources Ltd. (TSX-V:RK) ("Rockhaven") is pleased
to announce the results for the remaining seven diamond drill holes and other exploration
activities conducted during the reconnaissance phase of the 2017 program at its 100%
owned Klaza gold -silver property, located in the Dawson Range Gold Belt of southern
Yukon.
A total of 15,922 m in 96 holes were completed during the 2017 exploration program .
Results in this release are from diamond drilling, excavator trenching, soil sampling and
ground geophysical surveys that were designed to evaluate prospective areas of the Klaza
property, which lie outside of the known mineral resource area s. The program
successfully identified seven new mineralized zones and a number of geochemical and
geophysical anomalies, which are priority targets for follow-up drilling in 2018.
Highlights from this news release include:
A series of new mineralized veins were discovered in a single drill fence completed
north of the current resour ce area, returning 1.16 g/t gold and 18.7 g/t silver over
10.12 m, 12.60 g/t gold and 312 g/t silver over 0.46 m, 9.43 g/t gold and 180 g/t
silver over 0.86 m, and 5.63 g/t gold and 91.4 g/t silver over 0.94 m;
Trenching and prospecting samples collected at the Victoria Target, southeast of the
newly discovered veins , returned a chip sample grading 4.95 g/t gold and 135 g/t
silver over 1.5 m and rock samples with peak values of 35.3 g/t gold and 1,145 g/t
silver; and,
A new prospecting discovery at the Rusk Target, 5 km south of the current resource
area, identified northwest trending linear structures where the peak value from rock
sampling returned 2.82 g/t gold and 2,070 g/t silver.
“We are excited by the discovery of multiple mineralized structures north of the Klaza
Zone and consider th ese structures high priority target s for diamond drilling in 2018.”
stated Matt Turner, Rockhaven’s CEO. “The se new structures are located within 500 m
of the currently envisioned open pit and are similar in character to the known zones that
host the current inferred resource of 1,360,000 gold ounces.”
Northern Drill Fence
A fence, comprising five diamond drill holes, was completed north of the Central Klaza
Zone to test an area where no mechani zed exploration had been completed previously .
This drilling targeted a number of linear magnetic and electro -magnetic anomalies,
similar to those marking known mineralized zones. The southern three holes intersected
a series of semi-massive sulphide veins that are spatially associated with porphyry dykes.
These veins and dykes closely resemble those within the inferred resource.

Exploration in 2018 will test these newly identified structures along strike to the
northwest, within the Western Fault Block which hosts the high-grade Western BRX and
Western Klaza zones, and to the southeast where soil sampling has identified strong gold-
in-soil anomalies.
Significant drill results from the newly discovered vein zones are shown in Table I.

Rex and Chevron/Dickson Zones
The Rex Zone was discovered in 2016 , 1 km southeast of the Eastern BRX Zone (see
news release dated Sep tember 8, 2016) . In 2017, three additional holes were drilled
down-dip and along strike of the discovery hole. The most significant intersections came
from hole KL-17-434 located 75 m along strike to the northwest , as shown on Table II
below. Additional work is required to confirm the orientation and character of the
mineralization within the Rex Zone.
The Chevron and Dickson Zones are two of the eleven previously identified mineralized
zones within the core of the Klaza property. Four holes were drilled into these lightly
explored zones in 2017. The results from three of the four holes were previously released
(see Rockhaven news release dated September 26, 2017 ). Significant intersections from
the final hole (KL-17-390) are shown in Table II.

Encouraging results from recent surface exploration activities elsewhere on the 287 km 2
Klaza property are described in the following paragraphs. None of these outside targets
have been systematically trenched or drilled to date.
Victoria Target
Prospecting in late 2016 and early 2017 returned favourable results 3.2 km to the
southeast of the area of the inferred resources. Two grab samples returned 35.30 g/t gold
and 1,145 g/t silver, and 12.10 g/t gold and 2,360 g/t silver, respectively, from a broad
recessive linear feature. An e xcavator trench across the linear intersected two
mineralized intervals, which returned 5.43 g/t gold and 149 g/t silver over 1 .0 m and
4.95 g/t gold and 134.75 g/t silver over 1.5 m . An additional rock sample collected on
the eastern, untrenched flank of the linear yielded 7.81 g/t gold and 51.1 g/t silver ,
suggesting the potential for additional parallel veins.
Rusk Target
The Rusk Target, located 3.5 km south of the current inferred resource, features a gold,
silver, antimony and arsenic soil geochemical anomaly that spans an area of over 2.6 km2.
This target saw cursory exploration in the 1970s and 1980s and was acquired by
Rockhaven in mid -2015. It was the focus of a contour soil sampling program in 2016 ,
which produced the highest arsenic -in-soil anomaly (1,900 ppm) returned to date on the
Klaza property. Follow-up work in 2017 included ground geophysics, prospecting and
additional soil sampling.
A total of 36 rock samples were collected at the Rusk Target in 2017 , the best of which
yielded 2.82 g/t gold and 2 ,070 g/t silver . Ten of the 36 samples returned greater than
1.0 g/t gold and four returned greater than 1,000 g/t silver. The mineralized samples are
spatially related to northwest-trending linear structures marked by magnetic lows and
electro-magnetic conductors.
Val Target
4
The Val Target is located 2.5 km north of the historical Mount Nansen Mine and 6 km
southeast of the area of the inferred resources on the Klaza pr operty. It lies on the
northern slope of Back Creek, one of the most productive placer gold creeks in the Mount
Nansen Gold Camp. Previous work has outlined soil geochemical anomalies.
Exploration activity in 2017 consisted of ground based geophysical surveys, which
identified north -northwest trending linear magnetic lows and electro -magnetic
conductors.
QAQC
All analyses of core, rock and soil samples from the 2017 program were performed by
ALS Minerals with sample preparation in North Vancouver, Whitehorse, Yellowknife or
Thunder Bay and assays and geochemical analyses in North Vancouver . Samples were
routinely analyzed for gold by fire assay followed by atomic absorption (Au -AA24) and
48 other elements by inductively coupled plasma -mass spectrometry (ME -MS61).
Samples that exceeded the detection limits of the routine methods were assayed for silver,
copper, lead and zinc by inductively couple d plasma -atomic emission spectroscopy
(Ag/Cu/Pb/Zn - OG62) and gold by gravimetric analysis (Au -GRA22). Rigorous
procedures were in place regarding sample collection, chain of custody and data entry .
Certified assay standards, coarse reject duplicates, fi eld duplicates and blanks were
routinely inserted into the sample stream to ensure integrity of the assay process . All of
the results reported have passed the QAQC screening.
