Canstar Consolidates Mary March Land Position with

Strategic Eagleridge Option

Toronto, Ontario--(Newsfile Corp. - February 19, 2026) - Canstar Resources Inc. (TSXV:

ROX) (OTCID: CSRNF) ("Canstar" or the "Company") has entered into an option

agreement dated January 16, 2026 (the “Option Agreement”) with Eagleridge International

Limited (the “Optionor”) to acquire a 100% undivided interest in mineral licence 006894M

(17 claims) located adjacent to the Company’s Mary March Project in central

Newfoundland (the “Eagleridge Claims”).

The Eagleridge Claims directly adjoin Mary March at Beothuk Lake and extend Canstar’s

tenure across the projected eastern continuation of the Mary March–Nancy April

volcanogenic massive sulphide (“VMS”) system (Figure 1).

Juan Carlos Giron Jr., President & CEO, stated:

“This is a strategic consolidation of the Mary March system. The geology does not stop at

the former property boundary, and neither should our exploration. The Eagleridge Claims

extend our control over the projected eastern continuation of the Mary March–Nancy April

VMS system and allow us to execute our 2026 geophysical and drill programs without

constraint.

With our partnership with VMS Mining Corporation, a fully funded 2026 exploration

program, and multiple high-confidence targets emerging from our structural model, we

believe Mary March represents a rare opportunity — high-grade VMS potential in a proven

district that remains materially underexplored with modern tools.”

Strategic Rationale

This acquisition completes a key gap in Canstar’s land position over a structurally

complex, high-grade VMS system within the Buchans-Roberts Arm Belt — host to the

historic Buchans Mine, which produced 16.2 million tonnes of ore at average grades of

approximately 14.5% Zn, 7.6% Pb, 1.3% Cu, 126 g/t Ag and 1.37 g/t Au between 1928 and

1984.

Mary March has already delivered one of the most significant base metal drill intercepts in

the belt outside the historic mine area:

9.63 metres grading 4.2 g/t Au, 122 g/t Ag, 10.1% Zn, 1.8% Pb and 0.64% Cu1

Multiple historic drill holes extended eastward beneath Beothuk Lake into the Eagleridge

ground and encountered strongly altered felsic volcanic rocks consistent with VMS

footwall environments. The regional structural model — characterized by stacked thrust

panels — indicates that fault-offset repetitions of the Mary March–Nancy April system may

occur to the east.

By securing the Eagleridge Claims, Canstar:

• Consolidates control of the full projected strike and structural continuation of the

Mary March system

• Eliminates a historic property boundary that bisected the geological model

• Enables seamless execution of ground geophysics and drilling across the entire

target corridor

• Prevents competitive encroachment in a proven but underexplored sector of the

Buchans belt

Over the past 12 months, Canstar has staked new licenses and purchased claims from

prospectors to systematically expand and consolidate its land package at Mary March to

build a contiguous, district-scale position in what management believes is one of the most

prospective yet underexplored portions of the Buchans camp.

Canstar’s tenure across the projected eastern continuation of the Mary March–Nancy April

volcanogenic massive sulphide.

Integration into 2026 Exploration Program

The Eagleridge Claims are being immediately incorporated into Canstar’s winter 2026

technical/geophysical program, which includes:

• High-resolution drone magnetics

• Ground-based induced polarization (IP) surveys

• Borehole electromagnetic (EM) surveys of select historic drill holes

Continuous geophysical coverage across the former property boundary is expected to

materially enhance structural interpretation and drill targeting.

These programs are designed to refine high-confidence, structurally informed drill targets

in advance of Canstar’s fully funded 2026 drill campaign, expected to commence when

ground conditions permit in early 2026 under the Company’s strategic exploration JV with

VMS Mining Corp for up to $11.5 million.

Land Access Agreement

The Company has also entered into a land access agreement (the “Access Agreement”)

with a private landholder in the Mary March area. Under the terms of the Access

Agreement, dated February 4, 2026, Canstar may access the private land for its winter

geophysics program by issuing 79,000 common shares and making a one-time cash

payment of $7,500. The transaction remains subject to TSX Venture Exchange approval,

and all securities issued will be subject to a statutory hold period.

Option Agreement Terms

Under the terms of the Option Agreement, dated January 16, 2026, Canstar may acquire a

100% undivided interest in the Eagleridge Claims over a three-year period by issuing an

aggregate of 575,000 common shares, making aggregate cash payments of $110,000, and

incurring $450,000 in exploration expenditures. Upon receipt of TSX Venture Exchange

approval, the Company will issue 100,000 common shares and pay $10,000 in cash. On or

before the first anniversary of the agreement, Canstar must incur $100,000 in exploration

expenditures, issue 125,000 common shares and pay $25,000 in cash. On or before the

second anniversary, the Company must incur an additional $150,000 in expenditures,

issue 150,000 common shares and pay $30,000 in cash. On or before the third anniversary,

Canstar must incur a further $200,000 in expenditures, issue 200,000 common shares and

pay $45,000 in cash. Upon exercise of the option, the Property will be subject to a 1.0% net

smelter returns royalty. The transaction remains subject to TSX Venture Exchange

approval, and all securities issued will be subject to a statutory hold period.
