Rockhaven Receives Approval to Direct Ship High Grade from its
Klaza Gold-Silver Deposit, Yukon
Offtake and Credit Facility Agreements with Ocean Partners
June 1, 2026 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce
it has received approval from the Energy, Mines and Resources Branch of the Yukon Government
to extract high-grade Direct Shipping Oxide (“DSO”) material from its 100% owned Klaza
Deposit, Yukon. The Klaza Deposit is royalty free and road accessible. The permit allows for
trench excavation, extraction and shipment offsite of mineralized vein material to a depth of 3.5
meters from surface along the 460 meters of assay confirmed strike length of the Western BRX
Zone.
Statement by Matt Turner, President and CEO of Rockhaven:
“Rockhaven is excited to be gin the extraction of DSO material at the Western BRX Zone, with
surface grades in the upper tier of Canadian precious metal (gold+silver) deposits. Rockhaven
cannot speculate on the economic potential of this program, but by following a comprehensive set
of field p rotocols, it will collect invaluable information to support a potentially larger scale
development of the Klaza project, data which is expected to be incorporated into updated mineral
resource models and the advancement of a pre-feasibility study (“PFS”). In order to facilitate
this approach, Rockhaven has signed agreements for the excavation, crushing and transportation
scopes of the project, as well as an offtake agreement for the processing of the DSO material. The
offtake agreement also provides for a revolving credit facility to support the DSO extraction and
shipping. We plan to commence work in early June 2026.”
The 2026 DSO bulk sampling program at Klaza will be conducted along the surface trace of the
Western BRX Zone, one of twelve high -grade gold-silver zones discovered to date at the Klaza
property. The Western BRX Zone was selected for bulk sampling based on a 2025 work program
that successfully defined the width, grade and character of near -surface mineralization , which
exhibits oxidation of sulphides and probable supergene enrichment. A total of 34 vein exposures
were trenched and sampled across the trace of the 46 0 m long strike extent of the zone. The
average width of these exposures is 1.20 m. Results from this work are summarized in the table
below and a map showing the location of the trenches can be found here: Detailed WBRX Zone

DSO Program Details
The 2026 Direct Shipping Oxide Bulk Sample Program at Klaza will commence in early June and
is expected to run until early September. An excavator will be used to selectively trench and
extract the oxidized vein material . Much of the surface overburden on the Western BRX Zone
was removed during the 2025 program, which will allow bulk sampling to begin immediately upon
crews mobilizing to site. Further, due to its oxidized nature, the DSO material is free-digging (i.e.
does not require drilling and blasting before extraction). The depth of the bulk sample is expected
to be approximately 3.5 meters. After extraction, the material will be crushed to ½ inch size on -
site, bagged and then transported via 40-tonne highway trucks to a northern port for further
shipping to a smelter for processing.
Off-site Processing and Credit Facility
3
Rockhaven has entered into an agreement with Ocean Partners UK Limited (Ocean Partners), to
deliver up to 10,000 tonnes through the end of 2028 of DSO material to Ocean Partners’ facility
offshore. A pre-payment of up to 90% may be made to Rockhaven on material delivered to a
North American port from the property.
Rockhaven has also entered into a revolving credit facility with Ocean Partners, which allows for
the drawdown of up to US$1 .5 million. In exchange, Rockhaven has granted Ocean Partners
exclusive right to process any DSO material removed from the Klaza Project through the end of
2028. The credit facility will incur an interest rate of SOFR+6.50% annually.
Environmental and Reclamation:
As the bulk sample requires no use of water, blasting or traditional milling equipment, Rockhaven
will conduct a simple, environmentally conscious operation. All trenches will be backfilled,
recontoured and properly reclaimed after extraction of the DSO material.
Potential Future Implications:
Although the bulk sample program is the primary focus for Rockhaven in 2026, the Company may
conduct a drill program focused on mineral resource expans ion and infill drilling and to obtain
representative samples for further advanced metallurgical test work in support of a PFS . The
proposed drill program would be conducted in late 2026 and the results used in the contemplated
PFS.
The Klaza project has been explored extensively for 16 years, resulting in the discovery of a series
of twelve high-grade gold-silver veins with an aggregate assay confirmed cumulative strike length
of greater than 10 kms, as shown on Table 2 and a map showing the location of the drill holes and
zones can be found here (Main Mineralized Zones Map). Rockhaven has approved drill permits
for all mineralized veins for the next five years , with extensions to be allowed in future
applications.

Clarification of Economic Potential
The Company cautions that the decision to undertake small-scale bulk sampling activities at Klaza
was made without the benefit of a feasibility study , pre -feasibility study , or reported mineral
resources or mineral reserves demonstrating economic and technical viability and, as a result there
may be increased uncertainty of achieving any particular level of recovery of material or the cost
of such recovery. The Company cautions that, historically, such projects have a much higher risk
of economic and technical failure. There is no guarantee that bulk sampling will continue as
anticipated or at all or that anticipated production costs will be achieved. The failure to continue
production may have a material adverse impact on the Company's ability to generate revenue and
cash flow to fund operations. Failure to achieve anticipated production costs may have a material
adverse impact on the Company's cash flow and potential profitability. Should results from the
bulk sampling program prove posit ive, net proceeds may be used for working capital , further
exploration or to fund future economic studies ; however, there is no assurance that the bulk
sampling will generate net proceeds, after all costs, fees and charges, or that such will be available
to support future exploration or development decisions.
QA/QC
All analyses for trench and drill samples from this press release 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 induct ively 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 g ravimetric analysis (Au -GRA22). Rigorous procedures were in place regarding
sample collection, chain of custody and data entry. Certified assay standards 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.
