In connection with a new pushback in Aitik, production challenges have arisen as
a result of high deposits of the very hard rock type diorite. The occurrences
create challenges and mean that the production rate for the first quarter is
estimated to be just over 9 Mtonnes. For the full year 2025, production is
estimated at close to 40 Mtonnes. The copper grade is estimated at 0.16%, which
is in line with what was previously communicated.
In 2024, the Aitik copper mine began a new pushback, which means that mining
will take place from ground level and that the open pit will thus be expanded.
In this area, where half of Aitik´s production is now taking place, parts of the
ore are oxidized and contain deposits of the very hard rock type diorite. The
oxidization means a slight negative effect on recoveries and the hard rock means
that the capacity for grinding is clearly limited. This means that the
production rate for the first quarter is estimated at just over 9 Mtonnes.
Drilling has established that the diorite deposits will continue to affect the
production process in Aitik for the remainder of 2025. Aitik's total production
in 2025 is therefore estimated at close to 40 Mtonnes. The copper grade is
estimated at 0.16%, which is in line with what was previously communicated.
