Rockhaven Reports Multiple High-Grade Vein Exposures at its Klaza
Gold-Silver Project, Yukon
November 17, 20 25 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to
announce assay results from the 2025 exploration program at its 100% owned and road accessible
Klaza property, located in the Dawson Range Gold Belt of southern Yukon.
During the summer of 2025, Rockhaven conducted an excavator trenching program along the
surface trace of the Western BRX Zone, one of twelve high-grade gold-silver zones discovered to
date at Klaza. The purpose of this program was to: (1) determine the width, grade and character
of near-surface mineralization in the zone; (2) better define structural features and controls related
to the mineralization; and (3) establish the nature and depth of the oxide to sulphide transition
(visually and analytically) for use in planned PFS -level metallurgical studies. To complete this
evaluation, the organic overburden layer was first removed and much of the zone was stripped to
bedrock. A total of 34 vein exposures were then trenched and sampled across the trace of the 460
m long zone. The information collected from this work is fundamental to the future Klaza
economic studies and will assist Rockhaven’s planning for a potential bulk sampling program
scheduled for summer 2026.
Highlight assays from the 2025 Program include:
• 143 g/t gold and 1,080 g/t silver over 1.79 m (TR-25-118)
• 100 g/t gold and 773 g/t silver over 1.52 m (TR-25-121)
• 67 g/t gold and 758 g/t silver over 2.05 m (TR-25-105)
• 102 g/t gold and 1,535 g/t silver over 1.20 m (TR-25-120)
• 99 g/t gold and 763 g/t silver over 1.22 m (TR-25-108)
• 204 g/t gold and 893 g/t silver over 0.50 m (TR-25-100)
• 80.5 g/t gold and 580 g/t silver over 1.22 m (TR-25-123)
• 64.2 g/t gold and 577 g/t silver over 1.41 m (TR-25-124)
• 89.1 g/t gold and 1,445 g/t silver over 0.90 m (TR-25-132)
• 69 g/t gold and 581 g/t silver over 1.25 m (TR-25-117)
Statement by Matt Turner, President and CEO of Rockhaven:
“The 2025 program was successful in demonstrating continuous, high -grade gold and silver
mineralization in the near surface portion of the Western BRX Zone, while also identifying
important structural and mineralogic al features. Based on these results, Rockhaven has
commenced planning and permitting for a bulk sample in 2026, including engagement with Little
Salmon Carmacks First Nations and their Development Corporation. Rockhaven has also entered
the YESAB environmental assessment process as well as begun discussions with potential direct
shipping customers/traders and smelters . Given the grades of the Western BRX Zone, we see
potential for a fast payback, low impact scenario that should provide invaluable informa tion to
support potential larger scale development of the Klaza project.”

The Western BRX Zone
During the 2025 work program, a total of 188 rock samples were collected. The samples were
taken from excavator bucket test pits (to simulate bulk sampling) or from the rib of excavator
trenches, both of which were oriented perpendicular to the strike of the zone. Float samples were
collected from the floor of the stripped area, between test pits and trenches, to help demonstrate
continuity. A total of 34 new cuts were made across the Western BRX Zone, spaced between 5
and 20 m apart along the strike length of the Western BRX Zone, with the exception of a section
in the southern part of the zone which was exposed through three trenches spaced 40 m apart.
Near surface mineralization in the vein zone is altered to strong limonite and hematite surrounding
highly fractured, pitted and vuggy quartz. The mineralization has a distinctive red-orange colour
that is easily distinguished from adjacent grey to brown, clay altered granodiorite or feldspar -
porphyry dyke waste rock. The weathered wall rock has sharp contacts with the mineralization
and is highly fractured, which should greatly simplify extraction of a bulk sample. Adjacent test
pit samples are shown in Figure 1, demonstrating the different properties of the mineralized rock
versus the unmineralized waste. The depth of the bulk sample is expected to be approximately 2-
3 meters and will target only mineralized vein material.

Placer Claim Staking
Although all mineralized exposures are hosted in bedrock, the presence of placer gold and placer
workings in the area warranted Rockhaven staking five bench placer claims to cover the Western
BRX Zone. These placer claims are now added to the 1,478 quartz claims that are included in the
Klaza property.
QA/QC
All analyses for rock samples from the 2025 program were performed by ALS Minerals with
sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. Rock
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
4
collection, chain of custody and data entry. Certified assay stan dards 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.

of these results on mineral resource estimate ; the potential for future bulk samples or for new
discoveries including porphyry deposits; the results of planned metallurgical programs; the ability
of Rockhaven to obtain additional financing and the permits and approvals required for bulk
sampling and potential future development; whether or not the condition of the rock in situ will,
in fact, assist with its potential future extraction, the potential outcomes of any financial studies;

whether or not there is placer gold within the placer claims; the need to comply with environmental
and governmental regulations ; the results of engagement with First Nations ; fluctuations in the
prices of commodities; operating hazards and risks; competition and other risks and uncertainties,
including those descri bed in Rockhaven’s financial statements and MD&A available under the
Rockhaven profile at www.sedar.com. Additionally, Roc khaven cautions that a potential bulk
sample may be completed without the use of a third-party feasibility study and, as a result, may
have a higher risk of economic and technical failure. If and when the bulk sampling commences
at Klaza, there is no guarantee that the operation will continue as anticipated, or at all , or that
