CANTERRA MINERALS COMPLETES WINTER DRILLING AND COMMENCES GEOPHYSICAL SURVEY AT CRITICAL MINERALS AND GOLD PROJECTS IN CENTRAL NEWFOUNDLAND

Canterra Minerals Corp. continues to advance its critical and precious metals projects in central Newfoundland. Winter diamond drilling of eight holes totalling 2,386 metres was completed at its Buchans project, with assay results anticipated in Q2 2026. The company also initiated a high-resolution airborne magnetic survey over its Wilding gold project, which covers a 55-kilometre extension of the same mineralized structural corridor hosting Equinox Gold's Valentine mine, the largest gold mine in Atlantic Canada.

Highlights:

• Critical minerals projects:
• • Buchans winter drilling completed: 2,386 metres over eight diamond drill holes targeting resource extension, infill and exploration; assay results are anticipated later in Q2 2026;
  • Critical mineral asset consolidation: systematic integration of historical drilling and geophysics across six critical mineral deposits and prospects to define second half 2026 diamond drill targets;
• Wilding gold project:
• • Basal till drill program complete: 181 percussion holes along the 55-kilometre Valentine structural trend; assays expected in Q2 to Q3 2026;
  • High-resolution geophysics: initiated property-wide airborne magnetic survey on 25-metre line spacing to guide targets for diamond drilling during second half of 2026.

"It was a highly productive winter season across our projects in the central Newfoundland mining district. With winter drilling now complete at Buchans, we expect to soon demonstrate meaningful extensions to known mineralization and further validate the district-scale potential of this historic project. At the same time, our systematic data integration across our broader critical mineral portfolio is sharpening our targeting and ensuring capital is directed toward the highest-priority targets," stated Chris Pennimpede, president and chief executive officer. "Meanwhile, our basal till drill program and high-resolution magnetics survey at Wilding are designed to unlock the next level of gold discovery potential along the prolific Valentine Lake gold corridor."

Canterra Minerals has completed phase 1 winter diamond drilling at its Buchans critical minerals project (eight holes, 2,386 metres), with assay results expected in Q2 2026. Simultaneously, the company has initiated a high-resolution airborne magnetic infill survey over a select target area within the larger property and completed 181 basal till percussion holes at its Wilding gold project, an approximately 55-kilometre land package on the same structural corridor hosting Equinox Gold's Valentine mine, the largest gold mine in Atlantic Canada. Assay results from both Buchans and Wilding are expected in Q2 to Q3 2026, with findings expected to define second half 2026 diamond drill targets across both gold and critical minerals portfolios.

Completion of winter drilling at Buchans critical minerals project

Winter diamond drilling at the Buchans project is now complete across eight holes totalling 2,386 metres. Assay results are anticipated in Q2 2026. Drilling targeted two priority areas:

• West Clementine target: a multikilometre chargeability anomaly with stockwork mineralization, representing Canterra's first drill test of this target;
• Two Level/Lundberg: resource extension and infill holes designed to support a potential Lundberg resource update in Q4 2026/Q1 2027.

Wilding gold project

Basal till drilling program

Canterra has completed 181 basal till percussion holes:

• Method: samples collected beneath glacial overburden to vector directly toward concealed bedrock gold targets, bypassing outcrop limitations;
• Proven technique: basal till sampling has a strong record of unlocking world-class orogenic gold discoveries concealed beneath glacial cover, including in the Finnish Shield, a terrain analogous to central Newfoundland;
• Wilding analogy: Central Newfoundland and the Finnish Shield share comparable stratigraphy, topography and orogenic gold style; multiple till transport directions across the 55-kilometre trend allow basal till anomalies to vector geologists efficiently to bedrock source zones;
• Next steps: results expected Q2 to Q3 2026; findings will directly define second half 2026 drill targets.

High-resolution airborne magnetic survey:

• High-resolution magnetic infill survey initiated to delineate the favourable contact between the Valentine Lake intrusive suite and the overlying Rogerson Lake conglomerate;
• Past work indicates this contact is the primary geological marker for gold mineralization in the corridor;
• Timeline: completion and results expected by the end of Q2 2026.

Mineralization in the Finnish Shield is not necessarily indicative of mineralization that may be found on Canterra's properties.

Critical mineral portfolio -- Victoria Lake supergroup (VLSG) update

Canterra is advancing a systematic, belt-wide prospectivity assessment across its Victoria Lake supergroup (VLSG) critical mineral portfolio. These six resource-stage assets had never been explored under a single company. Canterra is now unifying all available data, including historical drilling, geophysical surveys and geological mapping, into a single modernized database to identify expansion opportunities and new discovery targets ahead of second half 2026 diamond drilling:

• Key assets with VLSG supergroup: Boomerang, Lemarchant, Long Lake, Tulks, Daniels Pond and Bobby's Pond deposits, all under unified management for the first time;
• Data integration: synthesizing historical drilling records, modern geophysical data sets and detailed geological mapping across all six deposits;
• Objective: unify project databases, digitize all available data and delineate priority drill targets for second half 2026 testing.

Election of semi-annual financial reporting

Canterra Minerals announces that it has elected to participate in the Coordinated Blanket Order 51-933, Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers. issued by the Canadian Securities Administrators.

The blanket order permits eligible venture issuers to voluntarily transition from quarterly to semi-annual financial reporting. The company has determined that it satisfies the eligibility requirements under the blanket order, including that it is a venture issuer with revenue of less than $10-million, has maintained a disclosure record of over 12 months and has filed all required periodic and timely disclosure documents.

As a result of this election, the company will file interim financial reports and related management discussion and analysis on a semi-annual basis, rather than quarterly. The company's fiscal year-end is Dec. 31 and will continue to file annual audited financial statements and will remain subject to all timely disclosure requirements for material information.

Pursuant to the blanket order, the company will be exempt from filing interim financial reports and related MD&A for its first and third quarters of its fiscal year. The first reporting period for which the company will rely on this exemption will be for the three-month period ended March 31, 2026. The company's next interim financial statements and related MD&A will be filed for the six months ending June 30, 2026.

This news release is being filed pursuant to the Coordinated Blanket Order 51-933, Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers.

About Canterra Minerals Corp.

Canterra is a diversified minerals exploration company focused on critical minerals and gold in central Newfoundland. The company's projects include seven mineral deposits located in close proximity to the world-renowned, past-producing Buchans mine and Teck Resources' Duck Pond mine, which collectively produced copper, zinc, lead, silver and gold. Several of Canterra's deposits support current and historical mineral resource estimates prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum definition standards for mineral resources and mineral reserves. Canterra's gold projects are located on trend of Equinox Gold's Valentine mine and cover an approximately 55-kilometre extension of the same structural corridor that hosts gold mineralization within Equinox Gold's mine. Past drilling by Canterra and others within the company's gold projects intersected multiple occurrences of orogenic-style gold mineralization within a large land position that remains underexplored.
