Rockhaven Drills Resource Step-Out Hole Grading 101 g/t Gold & 107
g/t Silver over 1.30 m at its Klaza Gold-Silver Project, Yukon
January 18, 202 3 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to
announce the first assay results from the 2022 exploration program at its 100% owned and road
accessible Klaza property. The Klaza property is located within the Dawson Range Gold-Copper
Belt of southern Yukon , a prolific belt that hosts several important mineral deposits including
Minto Metals’ Minto mine, Western Copper and Gold’s Casino deposit and Newmont’s Coffee
deposit.
2022 Program
During the summer of 202 2, a total of 12,042 m of drilling was completed in 69 holes at Klaza.
The work program was designed to advance Klaza towards an updated mineral resource estimate1
and pre-feasibility study by attaining the following objectives: (1) re-categorization of prioritized
inferred mineral resources i nto indicated mineral resources, (2) expansion of the total mineral
resource, (3) collection of samples for advanced -stage metallurgical test work, (4) completion of
additional geotechnical drilling for optimized open-pit and underground engineering; and, (5)
evaluation of some of the exploration targets that lie outside of the known mineral resource areas
through excavator trenching, soil sampling and prospecting.
Highlights
Highlight assays from this press release include:
• 101.5 g/t gold and 107 g/t silver over 1.30 m starting at 64 m (KL-22-624)
• 2.18 g/t gold and 199 g/t silver over 13.29 m starting at 193 m (KL-22-579)
• 6.91 g/t gold and 37 g/t silver over 6.62 m starting at 29 m (KL-22-563)
• 18.85 g/t gold and 347 g/t silver over 1.11 m starting at 93 m (KL-22-576)
All of the results in this new s release are from 22 holes drilled in 2022 within the Central and
Eastern BRX zones and the adjacent AEX Zone. Results from the remaining 47 holes completed
in other zones will be released in subsequent news releases.
Statement from Rockhaven’s President and CEO, Matt Turner:
Results from 2022 drilling at the Central BRX Zone confirm, and build upon, earlier results. These
results are expected to grow the total mineral resource at Klaza and upgrade mineral resources
previously defined at inferred to the indicated category.
Additionally, eight holes that tested the eastern projection of the BRX Zone returned promising
results that lie outside of the current mineral resource estimate. The main mineralized structure
was intersected in all of these holes, with the best intercept returning 101 g/t gold over 1.30 m in
hole KL-22-624.

Positive results were also obtained from the sub-parallel AEX Zone, located immediately south of
the BRX Zone, including the strongest intercept to date from that zone, averaging 6.91 g/t gold
over 6.62 m in hole KL-22-563.
Neither the AEX Zone nor the Eastern BRX Zone are currently included in the 2018 Klaza Property
Mineral Resource Estimate, but Rockhaven expects that mineralization in portions of these zones
will be added to the updated mineral resource estimate.
Central BRX Zone, Eastern BRX Zone, and AEX Zone
The Central BRX Zone hosts veins emplaced along the selvages of a single feldspar porphyry dyke
which runs the length of the zone. It hosts an indicated mineral resource estimate of 713,000
tonnes containing 53,000 oz gold, 2.84 million oz silver, 14.8 million lbs lead and 18.3 million lbs
zinc at an average grade of 2.3 g/t gold, 124 g/t silver, 0.9% lead and 1. 2% zinc and an inferred
mineral resource estimate of 1,425,000 tonnes containing 79,000 oz gold, 4,656,000 oz silver, 30.0
million lbs lead and 27.4 million lbs zinc at an average grade of 1.7 g/t gold, 102 g/t silver, 1.0%
lead and 0. 9% zinc (See July 10, 2020 Preliminary Economic Assessment on the Rockhaven
website (www.rockhavenresources.com)).
Prior to the 2022 program, t he Central BRX Zone ha d been traced for a strike length of 1.1 km ,
extending from the Western BRX Zone (the most significant mineralized zone identified to date
on the property) to the Eastern Zones, which hosts sheeted-vein, bulk tonnage style mineralization
not currently included in the Klaza Deposit mineral resources1.
Drilling in 2022 confirmed and better defined the eastern projection of the BRX Zone structure.
The eight holes completed within this area in 2022 , coupled with the results from past drill
campaigns, have increased confidence in the continuity of mineralization within the Eastern BRX
Zone, potentially leading to a 300 m long expansion of the mineral resource to the east. As final
assays have only just been received, resource modelling is currently in progress for this zone.
The AEX Zone, located just south of, and trending sub-parallel to, the Central BRX Zone, hosts
significant potential for near surface growth of mineral resources at Klaza. Step-back infill drilling
at the BRX Zone intersected AEX Zone mineralization in multiple holes , with the best result
returned from the top of hole KL-22-563, which averaged 6.91 g/t gold and 36.5 g/t silver over
6.62 m.

+ Represents the diamond drill hole core length. True widths are estimated to be 80 -90% of the interval as the majority of vein
intersects had contacts that were at or near perpendicular to core axis.
* Gold equivalent (AuEQ) values assume $1,800/oz Au, $22/oz Ag, $1.05/lb Pb, and $1.60/lb Zn, and variable recoveries for the
different metals. The equation used is AuEq=1*Au+Ag/103.42+Pb/4.64+Zn/3.63

Detailed maps showing the locations of completed drill holes can be viewed on the Rockhaven
website at www.rockhavenresources.com. Remaining results from the 2022 program will be
released once assays have been received, compiled and evaluated.
QA/QC
All analyses for rock and core samples from the 2022 program were performed by ALS Minerals
with sample preparation in Whitehorse, Yukon and Windsor, Ontario and assays and geochemical
analyses in North Vancouver. Core 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 coupled plasma -atomic emission
spectroscopy (Ag/Cu/Pb/Zn - OG62) and gold by gravimetri c analysis (Au -GRA22). Rigorous
procedures were in place regarding sample collection, chain of custody and data entry. Certified
assay standards, coarse reject duplicates, field 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 QA/QC screening.
