Canterra Minerals Extends Lundberg Deposit with 86m of 0.91% CuEq at Buchans Project, Newfoundland
Canterra Minerals Extends Lundberg Deposit with 86m of 0.91% CuEq at
Buchans Project, Newfoundland
VANCOUVER, British Columbia, Feb. 25, 2026 -- Canterra Minerals Corporation (TSXV:CTM) (OTCQB: CTMCF)
(FSE:DXZB) (“Canterra” or the “Company”) is pleased to announce drill results from the 2025 program at its Buchans Project
in the Central Newfoundland Mining District, extending mineralization at the Lundberg Deposit and validating new, deep-
seeking 3DIP targets across the district.
The 2025 results confirm depth continuity of the Lundberg system and support potential resource expansion within one of the
world’s highest-grade historic Volcanogenic Massive Sulphide (VMS) camps. With a fully funded winter 2026 drill program now
underway, the Company is advancing step-out and discovery drilling designed to generate successive catalysts throughout the
year.
2025 Drill Program Highlights:
• Lundberg Deposit Extended at Depth: An extension of hole H-25-3542 returned 86.0 metres grading 0.91% CuEq ,
extending the known Lundberg resource mineralization 75-100 metres below the previously defined resource limit
(Figures 1 & 2).
• High-Grade Sub-Intervals Within Extended Lundberg Broad Stockwork : (H-25-3542; Figure 2), including:
◦ 6.0 m at 3.43% CuEq and
◦ 22.0 m at 1.21% CuEq.
• Two Level Horizon Confirmed : The upper portion of H-25-3542 intersected 4.45 m grading 7.73% CuEq (previously
released), reinforcing the strength of mineralization within stacked horizons (Figure 2).
• Step-Out Success Demonstrates Lateral Continuity: Hole H-25-3553, drilled 50 m north of H-25-3542, intersected
7.0 m of stockwork grading 0.47% CuEq, confirming continuation of the system down dip (Figure 2).
• Clementine Extension: A 50 m step-out hole (H-25-3552) intersected 3.45 m grading 1.09% CuEq, supporting down-
plunge continuity (Figure 1).
• Priority 3DIP Targets: Drilling north of the Sandfill prospect intersected mineralization associated with a 1.5 km-long
3DIP chargeability anomaly that remains largely untested and a priority target for 2026 (Figure 3).
• Strategic Land Expansion at Nu Target: Following identification of potential Buchans mine trend stratigraphy,
Canterra staked an additional 13.5 km² (1,350 hectares), expanding the project to 106 km² and opening a new
southwest structural trend for follow-up drilling (Figure 1).
• 2026 Winter Drill Program Underway: A significant 2026 drill program has commenced to test high-conviction
targets across the property.
Chris Pennimpede, President and CEO of Canterra commented: “The extension of Lundberg confirms that mineralization
remains open at depth within this world-renowned, high-grade mining camp. Importantly, these results validate our 3DIP
targeting approach and provide clear vectors for follow-up drilling. With our fully funded 2026 program underway, we are
prioritizing capital toward high-conviction targets that can meaningfully expand resources or lead to new discoveries, all while
maintaining a disciplined approach to exploration spending.”

Exploration Discussion
Lundberg Deposit: Depth Expansion Within a Proven System
Hole H-25-3542 was originally drilled to test the Two Level horizon, returning 4.45 m grading 7.73% CuEq. Because the hole
ended in mineralized stockwork during initial drilling (see news release dated November 19, 2025), the Company elected to
extend it. The extension successfully intersected a broad 86.0 m interval averaging 0.91% CuEq, confirming continuity beyond
the previously defined limits. Higher-grade sub-intervals of 6.0 m at 3.43% CuEq and 22.0 m at 1.21% CuEq were also drilled,
highlighting the significant thickness and grade continuity of the system.
Step-out drilling continues to support lateral continuity. Hole H-25-3553, collared 50 m north of H-25-3542, intersected
additional stockwork mineralization further extending the footprint of the system, including 7.0 m grading 0.47% CuEq. To the
west, hole H-25-3554 (a 50 m step-out) returned 0.85 m at 0.58% CuEq within the Two Level horizon.
These results demonstrate that Lundberg remains an expandable system within the broader Buchans camp.
Clementine, Nu target and Sandfill Prospects
• Clementine : Drilling confirmed continued mineralization down plunge. Hole H-25-3552 was drilled 50 m south of H-25-
3546 and intersected 3.45 m grading 1.09% CuEq, confirming mineralization down-plunge. Hole H-25-3547 was
targeting a broad chargeability anomaly south of the main Clementine zone; the hole was lost in the fault zone before
reaching target depth. Additional 3DIP anomalies remain to be tested in the current winter campaign.
• Sandfill: Hole H-25-3555 intersected 1.0 m grading 0.45% CuEq, mineralization coincident with a large, 1.5 km-long
chargeability anomaly and associated alteration footprint, including a broad zone of Na ₂O depletion that appears to
broaden to ~200 m thickness in adjacent historical drill holes, a key VMS pathfinder. The majority of this 1.5 km
anomaly remains untested and is a high-priority target for 2026 drilling.
• Nu Target: Integration of VRIFY’s DORA targeting and 3DIP survey led to identification of Buchans stratigraphy along a
newly defined southwest trend, prompting a 13.5 km² property expansion.
Collectively, these targets provide multiple exploration vectors across the project and support a systematic, capital-efficient
exploration strategy.
Next Steps
The fully funded 2026 winter program has now commenced focusing on:
1. Testing depth and lateral continuity of the Two Level–Lundberg system .
2. Following up on high-priority 3DIP anomalies at West Clementine and Sandfill .
3. Initial groundwork on the newly acquired southern claims to explore extensions of the Buchans group rocks.
Located within a historic mining district with established infrastructure, Buchans enables cost-efficient drilling relative to
remote exploration environments, allowing greater metres per dollar deployed. Results from the winter campaign are expected
to provide a steady cadence of exploration catalysts throughout 2026.

About Canterra Minerals
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 National
Instrument 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 currently under
construction and cover a ~55 km 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.
QA/QC Protocols
Samples consist of saw-cut (NQ drill core) with one-half retained for reference and one-half submitted for analyses. Samples
were submitted in sealed plastic bags delivered by Canterra personnel to SGS Canada’s preparatory facility in Grand Falls-
Windsor, Newfoundland. 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, BC to be homogenized
and subsequently analyzed for multi-element assays (including Cu, Pb, Zn, Ag and Au) using sodium peroxide fusion with ICP
-OES finish (codes GE_ICP90A50 for Cu, Pb, Zn, Ag, GE_AAS42E50 for Ag by 4-acid digestion by AAS, and GE_FAA30V5
for Au by 30g Fire Assay by AAS). Overlimit assays were completed as necessary by pyrosulphate fusion/XRF for Cu, Pb, Zn
(code GO_XRF70V) and Ag by 30g 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 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. Further details regarding SGS procedures are available at SGS Analytical
Methods. Canterra also submits representative pulps to ALS Geochemistry’s laboratory in Moncton New Brunswick for
additional independent check assays.
