Canstar Resources Launches First Mary
March Drill Program Since 2019 as Earn-In
Partner VMSC Increases Phase 1 Investment to
C$2.0 Million
New geological model defines the drill targets now being
tested at the Mary March Project in Newfoundland
Toronto, Ontario--(Newsfile Corp. - June 17, 2026) - Canstar Resources Inc. (TSXV: ROX) ("
Canstar
" or
the "
Company
") has received an additional C$500,000 in exploration capital from the Company's joint
venture partner, VMS Mining Corporation ("VMSC") pursuant to VMSC's exercise of the Phase 1 Option
under the parties' earn-in agreement in respect of the Buchans and Mary March properties
.
The additional investment increases VMSC's total Phase 1 funding under the earn-in agreement to
C$2.0 million. Pursuant to the earn-in agreement, the Phase 1 Option entitles VMSC to acquire an
additional 5% indirect interest in the project-level vehicle on completion of the applicable acquisition
steps, increasing VMSC's total Phase 1 indirect interest from 10% to 15%. Consistent with all
investments under the earn-in structure, the funding is made directly at the project level and is non-dilutive
to Canstar's corporate share capital. Funding will advance the Mary March volcanogenic massive
sulphide ("VMS") Project, where the Company's first diamond drill program since 2019 has now
commenced.
Juan Carlos Giron Jr., President & CEO of Canstar, commented:
"This additional C$500,000 reinforces momentum at our flagship Mary March program as we begin
our first drilling campaign alongside a partner with whom we share deep alignment on exploration
philosophy and real excitement about this project's potential. Under the technical leadership of Dr.
Harold Gibson, a year of disciplined work - relogging more than 14,400 metres of historical core,
completing multiple geophysical surveys and building a "first principles" geological foundation - has
generated drill-ready targets and positioned us for an effective campaign. We are grateful to have a
partner in VMSC that values building that foundation the right way, and we believe this approach will
keep compounding."
Exploration Updates
Results of the recent field programs of trenching, mapping, airborne, ground and borehole geophysical
surveys, coupled with relogging of 14,400 metres of historic Mary March core incorporating systematic
surface and drill core lithogeochemical and pXRF surveys have generated a new geological model for
the Mary March area. This model extends the geochemically distinct, prospective felsic volcanic rocks
that host high-grade massive sulphide mineralization intercepted by historic drilling to two panels that lie
on the north and south limbs of a northeast-trending anticline whose south limb, which hosts the known
mineralization, is cut and repeated by a low-angle thrust fault. Chargeability anomalies detected in the
winter 2026 direct-current induced polarization ("DCIP") survey correlate well with alteration and
mineralization in the prospective rhyolite along the south limb of the anticline, and alteration and stringer
mineralization drilled at Nancy April lies in footwall rocks within the core of the anticline. A third DCIP
anomaly located down-dip of the prospective rhyolite along the north limb, along with alteration and
mineralization in the immediate footwall rocks, will be tested. The prospective rhyolite on the north limb of
the anticline had not been previously recognized. The planned drill program includes extending one
existing drill hole to penetrate the full thickness of the southeast limb rhyolites where they are most
altered, a second hole to intersect the rhyolites almost 500 metres southwest of their closest known
occurrence and three holes are planned to test the northwest anomaly.

Joint Venture Structure
Under the earn-in framework announced February 18, 2026, VMSC may earn up to a 60% indirect
interest in the project-level vehicle by investing an aggregate of C$11.5 million in project-level exploration
expenditures across three phases in accordance with the earn-in agreement. Exercise of the Phase 1
Option adds a further C$500,000 of investment - bringing total Phase 1 funding to C$2.0 million - and an
incremental 5% indirect interest, subject to completion of the applicable acquisition steps, increasing
VMSC's maximum potential indirect interest in the project-level vehicle to 65% and increasing maximum
aggregate capital in project-level expenditures across three phases to C$12 million. The drill program
represents the first test of targets generated by a new integrated geological model and marks a key step
in unlocking the broader Mary March VMS system.
