Dublin-headquartered Karelian Diamond Resources has received the results of a preliminary economic assessment (PEA) for its Lahtojoki kimberlite pipe in eastern Finland, which recommends that a mine should be developed to extract more than $200-million worth of diamonds.
The PEA, which was carried out by Brennan Mining Services, estimates that about 2.11-million carats could be recovered from a mine operating for nine years.
