Resource Mining Corporation Ltd (ASX:RMI) continues to pursue fieldwork at the Kola Lithium Project in Central Finland, buoyed by the presence of lithium-bearing pegmatites, including boulders.
Numerous boulders found
The company says it has found “many” of these new spodumene-pegmatite boulders during field exploration work at the 100%-owned project, pointing to the potential for lithium-bearing pegmatites in the northern part of the permit, along trend from Keliber’s deposits, which are under development by Sibanye Stillwater and the Finnish Government.
Boulders in this region are generally moved by glacial transportation processes with research by Finnish Geological Services indicating that this movement can be as far as 1.5 to 2 kilometres in a south-easterly direction from the pegmatitic source.
This means that the source or sources of the spodumene-containing boulders might be on the northern part of RMC’s Kola permit.
Source likely to be on permit
Data from a ground-penetrating radar (GPR) field survey is at the lab now and the results will help the company to find the bedrock source of the boulders.
Resource Mining Corporation CEO Andrew Nesbitt said: “We continue to find spodumene containing pegmatite boulders at Kola.
“Given the typical vector for local glacial transportation, the boulders are likely derived from lithium-pegmatite source rocks well within the Kola permit.
“Early results from the GPR survey are indicating that the depth of the boulder field is between two and 11 metres, significantly less than we previously anticipated.
“We are confident that the GPR work coupled with the latest fieldwork will lead to drill-worthy targets.”
Kola Lithium Project
The Kola reservation notification area, which is 101.26 square kilometres and sits in the Kaustinen lithium pegmatite province of Finland, borders the permits and applications of Keliber, a major new lithium project currently under development by owners Sibanye-Stillwater.
Fieldwork continues to identify lithium-containing pegmatite boulders in the Kola permit, along the same trend that hosts the Keliber lithium-pegmatite deposits.
Field observations and multi-element analysis of these new boulder samples and the results of the GPR survey will allow the company to reconstruct a boulder fan that vectors towards the source pegmatite.
The fieldwork continues southeast, along the identified trend, and more spodumene findings are expected. Spodumene-containing pegmatite boulders were also defined near the western border.
A geophysical survey has also been carried out, the results of which will be revealed when they become available.
