Resource & Technical Disclosure
Mineral resource information for Canterra’s Newfoundland projects, organized by deposit and linked to supporting technical reports.
Lundberg, Buchans
The Buchans project page reports the following Lundberg mineral resource figures. Indicated and Inferred resources are shown separately. The linked 2024 NI 43-101 technical report provides the detailed estimate basis, including its effective date, cut-off and material assumptions.
| Category | Tonnes | Zinc | Lead | Copper | Silver | Gold |
|---|---|---|---|---|---|---|
| Indicated | 16.79 Mt | 1.53% | 0.64% | 0.42% | 5.7 g/t | 0.07 g/t |
| Inferred | 0.38 Mt | 2.03% | 1.01% | 0.36% | 22.4 g/t | 0.31 g/t |
Inferred resources have greater geological uncertainty and are not added to the Indicated category. Figures may be rounded.
Other deposits in the portfolio
The following estimates are identified as historical on the project pages. They have different estimate dates, technical sources and cut-offs and should be read separately from the current Lundberg resource.
Lemarchant
Historical 2018 estimate reported using a 4.0% zinc-equivalent cut-off. The project page also links to a 2023 technical report.
Lemarchant project and reportsBoomerang & Domino
Historical estimates described in the 2007 Tulks South technical report. The project page reports a 1% zinc cut-off.
Boomerang & Domino projectLong Lake & Tulks Hill
Historical estimates from different technical sources: Long Lake (2012; 7.0% ZnEq) and Tulks Hill (1.1% CuEq).
Long Lake & Tulks projectDaniel’s Pond & Bobby’s Pond
Historical estimates sourced to 2008 technical reports. The source materials cite a 2% zinc cut-off for Daniel’s Pond and a 1.0% copper-equivalent cut-off for Bobby’s Pond.
Daniel’s Pond & Bobby’s Pond projectHow to read these figures
- Resource categories. Measured, Indicated and Inferred resources have different levels of geological confidence. Inferred quantities are reported separately.
- Current and historical information. Historical estimates are not included in the current Lundberg resource and should not be combined into a current portfolio resource total.
- Metal equivalents. ZnEq and CuEq figures depend on metal prices, recoveries, payability and calculation methods stated in the relevant source.
- Rounding. Reported figures may be rounded and may not sum precisely.
Technical reports
Canterra’s Investor Centre hosts technical reports, including the Lundberg, Lemarchant and Long Lake reports. The individual project pages provide further deposit-level tables, citations and explanatory notes.
