Rockhaven Ends 2022 Klaza Drill Program Reporting on a High Note
Drills 5.48 g/t Gold and 128 g/t Silver (7.00 g/t AuEq2) over 5.85 m at its Klaza Project, Yukon
March 1, 2023 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce
the final assay results from the 2022 diamond drilling program completed 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 copper -gold mine, Western Copper and Gold’s Casino copper -
gold deposit and Newmont’s Coffee gold deposit.
2022 Program
During the summer of 2022, a total of 12,042 m of drilling w as 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 resource s into 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; an d, (5)
evaluation of some of the exploration targets that lie outside of the known mineral resource areas
through excavator trenching, soil sampling and prospecting. Based on results received to date,
Rockhaven is on track to achieve all objectives.
Highlights
Results presented in this news release are from various parts of the Central Klaza Zone , the
adjacent BYG Zone and the Western BRX Zone Extension target. Previous 2022 season drill
results were announced on January 18th and January 30th, 2023.
Highlight assays from this press release include:
• 5.48 g/t gold and 128 g/t silver (7.00 g/t AuEq2) over 5.85 m (KL-22-603)
• 11.16 g/t gold and 23 g/t silver (11.82 g/t AuEq2) over 2.14 m (KL-22-600)
• 5.60 g/t gold and 174 g/t silver (8.29 g/t AuEq2) over 3.38 m (KL-22-596)
• 4.27 g/t gold and 352 g/t silver (8.44 g/t AuEq2) over 2.31 m (KL-22-590)
• 4.24 g/t gold and 38 g/t silver (4.69 g/t AuEq2) over 3.81 m (KL-22-602)
• 2.56 g/t gold and 14 g/t silver (2.78 g/t AuEq2) over 5.61 m (KL-22-611)
• 25.90 g/t gold and 258 g/t silver (30.50 g/t AuEq2) over 0.64 m (KL-22-594)
Statement from Rockhaven’s President and CEO, Matt Turner:
“Drilling completed at the Central Klaza Zone in 2022 primarily focused on areas to the east and
west of infill drilling done during the 2021 program. Although these areas were considered to be
lower priority targets coming into 2022, all 21 holes returned significant mineralization along the
2
targeted vein structures . The results are expected to be supportive of the potential project
economics because several intercepts are higher than deposit average grade and some, like the
interval averaging 7.00 g/t AuEq across 5.85 m in hole KL-22-603, are located near surface.”
“In addition to the resource definition holes, the 2022 drill program included several geotechnical
holes, the data from which will be used for engineering studies that will be an important part of
our planned pre-feasibility study. The engineering work includes rock strength testing and slope
stability studies, which are essential for optimizing pit shell design. The geotechnical holes were
drilled at oblique angles to the mineralized structures , targeting primarily the hanging wall and
footwall rocks and not the main mineralized structures . Nevertheless, a few of the geotechnical
holes intersected the veins, producing additional assay information that will be used to support
planned resource estimation. Of particular note, geotechnical hole KL-22-605 averaged 7.36 g/t
gold and 136 g/t silver over 5.70 m and KL-22-622 returned a weighted average grade of 2.85 g/t
gold and 41 g/t silver over 33.96 m, with individual assays of 65.8 g/t gold and 182 g/t silver over
1.07 m and 15 g/t gold and 957 g/t silver over 0.93 m, respectively.”
The Central Klaza Zone
The Central Klaza Zone hosts a laterally extensive complex of steeply dipping veins, breccias and
sheeted veinlets emplaced within a 25 to 100 m wide by 1,300 m long structural corridor. In 2022,
twenty-one in-fill holes were completed at the Central Klaza Zone. These holes were designed to
upgrade mineral resources from inferred to indicat ed and to collect material for advanced
metallurgical testing. Fourteen of the holes intersected the western portion of the zone, five
targeted its eastern side and two tested deeper, beneath the central portion. All holes returned
promising intercepts, with the most significant results coming from near surface hits on the eastern
side, where highlights include 7.00 g/t AuEq2 over 5.85 m, 2.78 g/t AuEq2 over 5.61 m, and 3.13
g/t AuEq2 over 3.08 m.

Engineering Work
Completed and planned e ngineering studies include geotechnical drilling and rock strength test
work. During the 2022 program, a total of 16 holes were completed to support the open-pit portion
of the planned pre-feasibility study. Holes were oriented oblique to the main zones, as previous
geotechnical drilling at Klaza had mainly been done in conjunction with exploration holes
designed to cut the veins perpendicular to strike. The holes completed in 2022 were structural
logged in detail to determine joint and fracture orientations and density and this data will be used
to optimize the slope of pit walls. Where the geotechnical holes intersected vein structures, grade
continuity within the resource models was also examined . Significant results from the
geotechnical holes are summarized in Table II. It should be noted that these holes crossed the
veins at oblique angles and their intersected widths do not represent true widths.

Rock strength test work on samples collected from the 2022 drill program includes uniaxial
compression strength, splitting tensile strength, triaxial compressive strength and direct shear
strength. These tests are currently in process.
The Western BRX Zone Extension
Two exploration drill holes targeted the potential eastern projection of the Western BRX Extension
target, an early stage exploration opportunity, which hosts a silver-rich vein discovered in KL-21-
492 (which returned 1,160 g/t silver, 8.4% lead and 5.2% zinc over 0.54 m, see press release dated
December 15, 2021). Drilling in 2022 returned one interval of note, grading 98 g/t silver over 0.90
m in KL-22-567. These results will assist in defining opportunities for potential extensions of the
Western BRX Extension target.
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 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 routin ely inserted into
the sample stream to ensure integrity of the assay process. All of the results reported have passed
the QA/QC screening.
