Canterra Minerals Corporation (TSXV:CTM) (OTCQB: CTMCF) (FSE:DXZB) announced drill results from its 2025 Buchans Project program.

  • Extension H-25-3542 returned 86.0 meters grading 0.91% CuEq, 75-100 meters below the previously defined resource limit; CuEq uses metal prices dated September 16, 2025.
  • The same hole included 6.0 meters at 3.43% CuEq and 22.0 meters at 1.21% CuEq; its upper portion had 4.45 meters at 7.73% CuEq, previously released.
  • Hole H-25-3553, drilled 50 meters north, intersected 7.0 meters grading 0.47% CuEq, extending the system down dip.
  • At Clementine, 50-meter step-out H-25-3552 intersected 3.45 meters grading 1.09% CuEq; H-25-3547 was lost in a fault zone before target depth.
  • H-25-3555 intersected 1.0 meter grading 0.45% CuEq beside a 1.5 km-long chargeability anomaly, most of which remains untested and is a priority for 2026 drilling.
  • The fully funded 2026 winter program has commenced to test Two Level-Lundberg continuity and 3DIP anomalies at West Clementine and Sandfill.
  • Canterra staked an additional 13.5 km² at the Nu target, expanding the project to 106 km².

Separately, the Grignan Holdings Ltd. dba Peterson Capital consulting agreement ends December 31, 2026; fees are $85,000 plus $5,000 in pre-approved expenses upfront.

Investor FAQs

Canterra Minerals Corporation (TSXV:CTM) (OTCQB: CTMCF) (FSE:DXZB) has announced drill results from its 2025 programme at the Buchans Project in the Central Newfoundland Mining District. The results include an extension of mineralisation at the Lundberg Deposit and drilling of 3DIP targets across the district.
An extension of hole H-25-3542 returned 86.0 metres averaging 0.91% CuEq, which the Company says extends known Lundberg resource mineralisation 75-100 metres below the previously defined resource limit. The hole also included 6.0 m at 3.43% CuEq and 22.0 m at 1.21% CuEq. The upper portion of the hole previously intersected 4.45 m grading 7.73% CuEq.
Hole H-25-3553, drilled 50 m north of H-25-3542, intersected 7.0 m grading 0.47% CuEq. Hole H-25-3554 returned 0.85 m at 0.58% CuEq. At Clementine, hole H-25-3552 intersected 3.45 m grading 1.09% CuEq. At Sandfill, hole H-25-3555 intersected 1.0 m grading 0.45% CuEq. Hole H-25-3547 was lost in a fault zone before reaching target depth.
The Company says its 2026 winter drill programme has commenced and is focused on testing depth and lateral continuity of the Two Level–Lundberg system, following up on 3DIP anomalies at West Clementine and Sandfill, and beginning groundwork on newly acquired southern claims. A 1.5 km-long chargeability anomaly at Sandfill remains largely untested, and additional 3DIP anomalies at Clementine remain to be tested.
Canterra staked an additional 13.5 km², or 1,350 hectares, at the Nu target. The Company says this expanded the project to 106 km² and opened a new southwest structural trend for follow-up drilling.
The release states that CuEq% is calculated using metal prices as of September 16, 2025. It lists prices of Cu 4.54$US/lb, Pb 0.88$/lb, Zn 1.35 $US/lb, Ag 42.55 $US/oz and Au 3692.80 $US/oz, together with stated recoveries of 90.41% Zn, 91.32% Pb, 91.14% Cu, 32.12% Au and 72.87% Ag. The release also says true widths are estimated to be a ~80-90% of reported core lengths.
The Company cautions that forward-looking statements may not prove accurate and that actual results and future events could differ materially. Identified risks include accidents and other mineral exploration risks, unanticipated geological factors, difficulties securing permitting and governmental clearances, insufficient funding to carry out business plans, and political uncertainties or regulatory or legal changes.
