Rockhaven Reports 2021 Rusk Zone Drill Results at its Klaza Gold-
Silver Project, Yukon
Rusk Vein System Expanded to 300m with Drill Highlights of 10.8g/t AuEq1 across 2.3m,
4.3g/t AuEq1 across 5.4m & 3.5g/t AuEq1 across 5.3m
March 16, 2022 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to
announce the remaining 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
objectives of this drilling were: (1) expansion of existing mineral resources, (2) re -categorization
of some inferred mineral resources into indicated mineral r esources, (3) in-filling of gaps in drill
patterns that are currently categorized as waste rock within existing resource areas, and (4)
evaluation of exploration targets that lie outside of the known mineral resource areas. The results
discussed in this press release are from 10 holes testing the Rusk Zone, a new vein complex that
was discovered through diamond drilling in 2020 . These holes focused on Objective 4 – the
evaluation of exploration targets outside of the known mineral resources.
All drill holes testing the Rusk Zone structure have returned significant mineralization. Highlight
drill assays from the 2021 work program at Rusk are:
• 5.0 g/t gold and 336 g/t silver (10.8 g/t AuEq1) over 2.26 m (KL-21-523)
• 3.1 g/t gold and 62 g/t silver (4.3 g/t AuEq1) over 5.42 m (KL-21-542)
• 2.2 g/t gold and 69 g/t silver (3.5 g/t AuEq1) over 5.32 m (KL-21-559)
• 1.2 g/t gold and 20 g/t silver (1.6 g/t AuEq1) over 8.72 m (KL-21-560)
• 1.1 g/t gold and 56 g/t silver (1.9 g/t AuEq1) over 6.73 m (KL-21-558)
“The 2020 and 2021 drill results from the Rusk Zone have identified a broad mineralized corridor
that is over 300 m long and is open for expansion along strike and to depth ,” stated Matt Turner,
Rockhaven’s CEO. “Rusk has received only a small fraction (~2%) of the total drilling completed
at the Klaza Deposit2 to date and may have positive implications for the scope and timing of the
potential development at Klaza. Additional drilling is planned to further evaluate the Rusk Zone
in 2022.”
Rusk Zone
The road-accessible Rusk Zone is located 3 km southeast of the Klaza Deposit and was first
identified through soil geochemical sampling and geophysical surveys. A maiden diamond drill
program in 2020 confirmed the presence of a new vein complex, with numerous high-grade gold,
silver, lead and zinc veins discovered in a fence of holes drilled across the 2.6 km 2 multi-element
soil geochemical anomaly. As highlighted in Rockhaven’s February 24, 2022 press release, 450
m of mechanized trenching were completed before the 2021 drilling commenced. This trenching
returned encouraging results from several mineralized structure s located up-dip of 2020 drill
intercepts, including 2.1 g/t gold, 125 g/t silver, 1.3% lead and 1.3% zinc across 8.7 m from the
strongest structure . This structure has now been tested by 11 diamond drill holes , spaced
approximately 50 m apart, over a 300 m strike length and to a maximum depth of approximately
200 m. The zone is open for expansion along strike in both directions and to depth.
Mineralization and controlling structures at Rusk generally resemble those at other zones in the
Klaza Deposit but contain proportionally more silver and less gold on average. They typically
consist of galena, sphalerite, pyrite and arsenopyrite in a quartz -carbonate gangue. At least two
generations of veins have been recognized at Rusk, with the earlier set trending west-northwesterly
and the second set more northerly. The northerly set often occurs along the margins of feldspar
porphyry dykes. A syn- to post-mineralizing sinistral fault, trending northeasterly, offsets the zone
by approximately 120 m. Maps showing the geology of the Rusk Zo ne and the locations of drill
holes, cross-sections and core photos of mineralized veins at the Rusk Zone can be viewed on the
Rockhaven website at www.rockhavenresources.com.

+ 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.

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 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 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 duplicates and blanks were routinely inserte d into the sample stream to ensure
integrity of the assay process. All of the results reported have passed the QA/QC screening.
