Parent companies of Peru's mining concession holders: a lookup table
Publicado el 10 de noviembre de 2026
Peru's mining cadastre (INGEMMET's GEOCATMIN) lists each concession under the name of its holder, the Peruvian company that holds it, and does not show the parent company. For example, Newmont's concessions are listed under MINERA YANACOCHA S.R.L. The table below brings together, for the holders with the most concessions and for companies that people often search for by name, the parent company or group, other shareholders or the previous owner, and the name of the mine or project, with a link to the source of each entry.

How to read the table
Each row is a holder with the name shown in the cadastre and the number of concessions it has in the national concessions layer. The other columns are:
- Parent or group: the holder's current parent company or the group it belongs to.
- Other shareholders or previous owner: the shareholders of a joint venture that do not hold the majority, and the parent company the holder had before a sale changed its owner.
- Mine, project or former name: the name of the mine or project, and the holder's former company name (marked "formerly:").
- The link next to each name goes to the source of that entry, and the date is the date of that document.
Table of holders and parent companies
How the table was made
We reviewed the holders with the most concessions in the national concessions layer of 10 November 2026 (the top 84) and other well-known companies. The sources are the official websites of the companies and their parents, filings with stock exchanges and securities regulators, GLEIF (the public register of LEI codes) and dated articles in the trade press.
For each row we opened the source page and published the row only if that page shows the name of the holder (or of the mine) and the name of the parent. Holders that are natural persons are not included.
Search the map by parent company name
If you type the name of a parent company (for example, newmont) into the search box of the map, the concessions of its holders appear. It also works with typos (newmount). When you select a holder you see the number and area of its concessions and the activity of the last 30 days: concessions whose status changed and new claims (petitorios) within 10 km.
Limits
The table does not include every holder: most holders with few concessions have not been reviewed. Owners change through sales and mergers, so each row holds as of the date of its source document.
If you find an error or an outdated row, please let us know through contact. To check the cadastre itself, use INGEMMET's GEOCATMIN and SIDEMCAT.
