Copper research sample / Free download
Filter projects, locate changes and check the original evidence. A workbook, a real change log and a bilingual newsletter use the same records to reduce source hunting, retyping and version comparison.
Filter Projects by CL to find Candelaria, Caserones, Centinela and Los Pelambres. Keep the period, output basis, status and source with each number.
Preparation already done: locating disclosures, transcribing output, and matching projects and periods.
Use CU-001, CU-003 and CU-005. A withdrawn forecast stays blank, earlier versions remain visible and source locations are linked.
Preparation already done: comparing old releases and rebuilding the guidance timeline.
Use CU-002, CU-004 and CU-006 to distinguish a partial restart, restored transport and commercial production at an expansion.
Preparation already done: reconstructing operating status and identifying double-counting risks.
All eight records cover calendar 2025, in tonnes of copper on a 100% project basis. This selected sample is not a ranking or global coverage estimate.
On narrow screens, scroll the table horizontally to read the full basis.
| Project | Country | 2025 output (t) | Status and reporting boundary |
|---|---|---|---|
| Las Bambas | PE | 410,834 | Reported Copper contained in concentrate, full year, 100% project. |
| Kamoa-Kakula | CD | 385,808 | Reported Phases 1–3 concentrators only. Excludes 3,030 t from the slag concentrator; issuer total is 388,838 t. |
| Kansanshi | ZM | 181,000 | Preliminary Preliminary output, reported as 181 kt, including S3. Not replaced with later final results. |
| Sentinel | ZM | 189,000 | Preliminary Preliminary output, reported as 189 kt. Excludes Enterprise nickel. |
| Candelaria | CL | 145,471 | Reported Issuer explicitly reports 100% production; do not multiply by Lundin’s 80% ownership. |
| Caserones | CL | 132,881 | Reported Issuer explicitly reports 100% production; do not multiply by Lundin’s 70% ownership. |
| Centinela | CL | 240,400 | Reported Concentrate copper plus cathodes. Do not add child facilities. Page publication date not stated. |
| Los Pelambres | CL | 295,300 | Reported Full-project annual copper output; do not scale by 60% ownership. Page publication date not stated. |
The two First Quantum records retain their preliminary status. Kamoa-Kakula uses phases 1–3 concentrator output and excludes the slag concentrator. No cross-project total is calculated.
The newsletter explains what changed, which field to update and what evidence to follow next. Stable record IDs connect each story to the workbook and CSV files.
The sample organizes source links, names, periods, before-and-after states and reporting differences. You decide how each change fits your model.
The timing cells are intentionally blank. Complete the same task manually and with the sample, check that the answers agree, then record both times. Time savings have not yet been measured.
