In brief
On 5 December 2025, the National Mining Secretariat published Resolution No. 101/2025 (“Resolution”). The Resolution establishes the updated annual mining fee (canon) that holders of mining rights must pay, with an increase of 31.3%.
As the canon is payable in advance and in two equal installments, due on 30 June and 31 December each year, the updated amount of the canon for the first half of 2026 is due on 31 December 2025.
In focus
The Resolution updated the annual mining canon per tenement using the consumer price index, as follows:
| First category substances (lithium, gold, silver, copper, etc.) | ARS 17,740.09 |
| Second category substances | ARS 8,963.42 |
| Provisional explorations or concessions of first and second category for one unit of measurement (500 ha) |
ARS 90,381.06 |
As an example, the following table compares the canon for 2025 with that for 2026, assuming a 10,000‑hectare exploration and a concession of 35 tenements, both assumptions for first-category minerals:
| Canon 2025 |
Canon 2026 | |||
| ARS | USD TC official (*) | ARS | USD TC official (**) |
|
| Exploration permit 20 units = 10,000 ha |
1,376,710.8 | 1,360.4 | 1,807,621.2 | 1,282.0008 |
| One category disseminated mine 35 tenements = 3,500 ha |
4,728,888.5 | 4,672.8 | 6,209,031.5 | 4,403.56 |
