CANTERRA MINERALS INTERSECTS 16.0 METRES OF 1.72% COPPER EQUIVALENT AT CLEMENTINE PROSPECT, 4 KM NORTHWEST OF PAST-PRODUCING BUCHANS MINE

Canterra Minerals Corp. has released its first drill results from the Clementine prospect, part of its 100-per-cent-owned Buchans project in the central Newfoundland mining district. The Buchans project is located 50 kilometres north of Equinox Gold's Valentine gold mine and 34 km northwest of Teck's past-producing Duck Pond mine. The Clementine prospect is located four km northwest of Canterra's Lundberg deposit and the past-producing Buchans mine.

Initial drilling has successfully extended known high-grade, Buchans-style mineralization and confirmed significant grades at the margin of historic mineralization. Importantly, results coincide with a large, untested chargeability anomaly identified by Canterra's recently completed deep-penetrating 3-D IP (induced polarization) survey, suggesting potential for a larger, higher-grade zone immediately to the south.

In response to these positive results, the company has mobilized a second drill rig to site as part of the continuing 10,000-metre drill program at its Buchans project.

Highlights:

• 1.72 per cent copper equivalent over 16.0 metres (H-25-3546, from 271.6 m depth), including 3.15 per cent CuEq over 2.0 m;
• 2.64 per cent CuEq over 3.0 m (H-25-3545, from 332 m depth), including 4.02 per cent CuEq over 1.0 m;
• Confirms high-grade, classic Buchans-style mineralization in an underexplored area;
• Results include gold and silver credits, which are common in Buchans-style mineralization;
• Expands prospectivity south of the prospect, where newly generated 3-D IP geophysical anomalies identify priority targets for follow-up drilling.

Chris Pennimpede, president and chief executive officer of Canterra, commented: "These first results from Clementine validate our exploration model and belief that our Buchans project has the potential to host multiple high-grade mineralized zones. We have confirmed thick, high-grade Buchans-style mineralization at the edge of the known system, with the potential for more continuous zones. Just as importantly, the correlation with a large IP anomaly to the south gives us a compelling large-scale target to test. This elevates Clementine on our priority list, and we are moving quickly to test the anomaly in the current phase of 2025 drilling."

Drill result analysis

The two holes reported tested extensions of historic drilling and successfully demonstrated true mineralized thickness exceeding 10 metres in hole H-25-3546. This style of transported, breccia-hosted sulphide mineralization was the primary source of the historic high-grade production at the Buchans mine.

This thicker interval occurs in a southern portion of Clementine that corresponds with broad chargeability and resistivity anomalies identified in Canterra's recently completed 3-D IP geophysical survey, providing strong evidence of a larger sulphide system.

Next steps

Following these successful results, Canterra is planning immediate follow-up drilling to test the continuity and extent of mineralization at the Clementine prospect. A key focus will be the Clementine South area, where recent 3-D IP surveys have identified several promising, untested targets characterized by strong chargeability response anomalies similar to those associated with the mineralization in hole H-25-3546. The company's continuing 10,000-metre drill program will also continue to test other high-priority targets across the wider Buchans project.

Buchans project

Canterra's Buchans project is a brownfield project covering 95 square kilometres near the town of Buchans. The project hosts the world-renowned, past-producing Buchans mine, which was operated by Asarco from 1928 to 1984 and was one of the world's highest-grade base metal mines. Adjacent to this legacy operation, the property also hosts the undeveloped Lundberg deposit, a significant near-surface resource of stockwork sulphide mineralization well suited for open-pit development.

Newfoundland and Labrador junior exploration assistance

Canterra would like to acknowledge financial support it may receive from the government of Newfoundland and Labrador's junior exploration assistance program related to completion of its 2025 exploration programs at Buchans.

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 six 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 National Instrument 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum's definition standards for mineral resources and minerals. Canterra's gold projects are located on trend of Equinox Gold's Valentine mine currently under construction and cover an approximately 60-kilometre extension of the same structural corridor that hosts mineralization within Equinox Gold's mine project. 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.

Quality assurance/quality control protocols

Samples consist of saw-cut (NQ) drill core, with one-half retained for reference and one-half submitted for analysis. Samples were submitted in sealed plastic bags delivered by Canterra personnel to SGS Canada's preparatory facility in Grand Falls-Windsor, Nfld. Sample batches consisted of core samples, control standards, blanks and duplicates. Once prepared, pulps (SGS procedure code PRP89) were shipped to SGS Canada's laboratory in Burnaby, B.C., to be homogenized and subsequently analyzed for multielement assays (including copper, lead, zinc, silver and gold) using sodium peroxide fusion with ICP-OES finish (codes GE_ICP90A50 for copper, lead, zinc and silver, GE_AAS42E50 for silver by four-acid digestion by AAS, and GE_FAA30V5 for gold by 30-gram fire assay by AAS). Overlimit assays were completed as necessary by pyrosulphate fusion/XRF (X-ray fluorescence) for copper, lead and zinc (code GO_XRF70V) and silver by 30-gram fire assay, gravimetric (code GO_FAG37V). SGS Natural Resources' analytical laboratories operate under a quality management system that complies with ISO/IEC 17025. SGS Canada's minerals laboratory in Burnaby is accredited by the Standards Council of Canada (SCC) for specific mineral tests listed on the scope of accreditation to the ISO/IEC 17025 standard. Canterra also submits representative pulps to ALS Geochemistry's laboratory in Moncton, N.B., for additional independent check assays.
