Karelian Diamond said it expects its permit for the Lahtojoki diamond project in Finland to come through in June.
A final public meeting to decide compensation for landholders will take place ahead of that date and following that Karelian expects to receive approval.
Elsewhere, Karelian reported that a sampling programme in Northern Ireland showed highly anomalous amounts of chromite raising the possibility of the presence of nickel-copper-platinum mineralisation on its acreage there.
Richard Conroy, chairman, added: “I am very pleased that progress towards completion of the National Land Survey’s procedures regarding the Lahtojoki diamond deposit is underway and that we now have a definitive timeline to work to.
"We look forward to obtaining a full mining permit, in due course, and moving ahead with the development of the mine. I also expect further exploration success in both Finland and Ireland.”
Karelian posted a profit of €99,000 (Loss:€193,000) in the half-year to end November 2021.
