Rockhaven Reports Multiple Wide, High-Grade Intercepts at its Klaza
Gold-Silver Project, Yukon
Including 5.4g/t AuEq1 over 8.3m, 3.2g/t AuEq1 over 12.9m & 8.0g/t AuEq1 over 4.9m
March 7, 2022 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce
additional assay results from the 2021 exploration program at its 100% owned and road accessible
Klaza property, located in the Dawson Range Gold Belt of southern Yukon.
During summer and fall of 2021, a total of 14,256 m of drilling was completed in 72 holes. The
results discussed in this press release include 23 holes testing portions of the two main mineralized
structures on the property, the Klaza and BRX zones, with the objective of upgrading and
expanding the Klaza property mineral resources2. Results from the first 39 drill holes completed
in 2021 were released on December 15, 2021 and February 7, 2022 . Results from the remaining
10 holes will be announced when assays have been received, checked and compiled.
Maps showing the locations of all drill holes, cross-sections and core photos of mineralized veins
can be viewed on the Rockhaven website at www.rockhavenresources.com. Highlight assay
results from the 23 holes covered in this press release include:

“The 2021 drilling within or adjacent to Klaza mineral resources2 was very successful, both filling
gaps within underexplored portions of the mineral resource areas and continuing with the objective
to upgrade inferred to indicated mineral resources,” stated Matt Turner, Rockhaven’s CEO. “We
were especially impressed by the results from the Central BRX Zone, which has seen mostly
shallow drilling along its 1.1 km strike length and may play a key role in the next phase of resource
expansion at Klaza.”
Central BRX Zone and AEX Zone
The Central BRX Zone has been traced for a strike length of 1.1 km. It is flanked to the west by
the Western BRX Zone (the most significant mineralized zone identified to date on the property),
to the east by the Eastern Zones (which hosts bulk tonnage style mineralization not currently
included in the Klaza Deposit mineral resources2), and to the south by the relatively untested AEX
Zone.
The Central BRX Zone currently comprises only a small percentage of the total mineral resources2
at Klaza, in part because it has received much less drilling than other zones in the deposit . The
results announced today, combined with previously announced results from 2021 drilling at this
zone (see Rockhaven Press Release dated December 15, 2021), demonstrate its potential to
contribute to growth of the mineral resources.
A nearby area that could also be important to growth of mineral resources is the AEX Zone, which
approximately parallels the BRX Zone, 125 m to the south. Step -back drilling at the BRX Zone
has intersected AEX Zone mineralization, as reported at the top of hole KL -21-553, which
averaged 1.5 g/t gold over 7.65 m, starting only 5.75 m from surface. Significant results from the
2021 drilling at the Central BRX Zone and AEX Zone announced in this press release are tabulated
below.

Klaza Zone
The Klaza Zone consists of the Eastern Klaza, Central Klaza and Western Klaza zones, collectively
traced for over a 2.1 km strike length. The Central and Eastern Klaza zones host a laterally
extensive complex of steeply dipping veins, breccias and sheeted veinlets emplaced within a 25 to
100 m wide structural corridor. The Western Klaza Zone differs in that it consists of a single
discrete vein that hosts a higher proportion of silver than gold compared with the other two portions
of the zone. In 2021, eight holes were completed at the Central Klaza Zone and three holes were
completed at the Western Klaza Zone, all were designed to convert inferred to indicated resources
and collect material for advanced metallurgical testing . Three holes were also completed at the
Eastern Klaza Zone near historical holes that contained promising intercepts. The Eastern Klaza
Zone does not currently host mineral resources.
Significant results from the 2021 drilling at the Central Klaza Zone (C. Klaza), the Western Klaza
Zone (W. Klaza) and the Eastern Klaza Zone (E. Klaza) announced in this press release are
tabulated below.

Resource Estimate
Rockhaven has elected to forego the updated resource estim ate planned for this spring, due to
delayed receipt of assays from the 2021 exploration program and the pending start of the 2022
exploration program. Infill drilling has consistently returned as expected, or better than expected,
results, thus the planning of hole locations to complete the conversion of inferred resources to
indicated resources is not dependent upon an updated resource estimation. An updated resource
estimation including results from the 2022 exploration program will have to be done befo re the
planned pre-feasibility study can begin.
QA/QC
All analyses for rock and core samples from the 2021 program were performed by ALS Minerals
with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver.
Core samples were routinely analyzed for gold by fire assay followed b y 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 gravimetric analysis (Au -GRA22). Rigorous procedures were in place regarding
sample collection, chain of custody and data entry. Certified assay standards, coarse reject
duplicates, field duplicat es 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.
