What mineral resource information does the release provide for the Lundberg deposit?

The release gives a Lundberg Mineral Resource Estimate with an effective date of February 28, 2019. It reports In-pit Indicated Mineral Resources of 16,790,000 tonnes grading 0.42% Cu, 1.53% Zn, 0.64% Pb, 5.69 g/t Ag and 0.07 g/t Au, and In-pit Inferred Mineral Resources of 380,000 tonnes grading 0.36% Cu, 2.03% Zn, 1.01% Pb, 22.35 g/t Ag and 0.31 g/t Au. The release states that the drill results are outside the existing resource area, but does not state that the resource estimate has been updated.

How were the copper-equivalent grades calculated?

The release states that CuEq values were based on total contained copper, zinc, lead, silver and gold using metal prices as of April 11, 2025: Cu - US$4.06/lb, Zn - US$1.19/lb, Pb - US$0.85/lb, Ag - US$32.23/oz and Au - US$3,236.00/oz. It also states that metal recoveries were assumed to be 100% (Rec.). The release provides the calculation formula and notes that true widths were estimated to be a ~90% of reported core lengths.

What are the main risks and uncertainties identified by the company?

The company states that exploration results and forward-looking information may differ materially from expectations. Identified risks include possible accidents and other risks associated with mineral exploration operations, unanticipated geological factors, the company’s ability to secure permitting and other governmental clearances, its ability to raise sufficient funds to carry out its business plans, and political uncertainties or regulatory or legal changes. The release also states that readers should not place undue reliance on its forward-looking statements.

How were the drill samples analysed and independently checked?

The release states that saw-cut NQ drill core was split, with one-half retained and one-half submitted for analysis. Samples were delivered to SGS Canada, with batches including control standards, blanks and duplicates. SGS used the procedures described in the release for multi-element assays and overlimit assays, and its laboratories operate under a Quality Management System complying with ISO/IEC 17025. Canterra also submits representative pulps to ALS Geochemistry’s laboratory in Moncton, New Brunswick for additional independent check assays.

Announcement Summary

Canterra Minerals Corporation (TSXV:CTM) (OTCQB: CTMCF) (FSE:DXZB) reported new drill results from the Buchans Project in Newfoundland.

Drillhole H-25-3538 returned 60.70 metres grading 0.85% CuEq from 15.3 metres to 76 metres below surface.
The interval included 4.7 metres grading 2.29% CuEq, with 1.19% Cu, 2.25% Zn, 1.27% Pb, 9.3 g/t Ag and 0.06 g/t Au.
The 60.70-metre interval graded 0.39% Cu, 1.00% Zn, 0.55% Pb, 2.5 g/t Ag and 0.03 g/t Au.
Canterra said broad sulphide stockwork mineralization extends below the current resource, suggesting potential for a larger open-pit mineral resource.
The ongoing 10,000 metre program covers the 100% owned project; the company said 8,000 metres remain this summer and fall.
The project is located in Newfoundland’s Central Mining District, near the town of Buchans.
