I thought we had finished with discussions on NaF. It seems not.
GBB is correct however, and NaF (Villiaumite) is found at average concentrations up to ~2wt% in all drill cores in the rock type (Iujavrite) found in the Ilimaussaq alkaline complex Kranfjeild. Generally, levels below this were found (1-1.5wt%). GML have known of this for many years, and have adequately allowed for it in the design of the concentrator circuit of the process, where it will be converted to CaF₂ (Fluorspar) and sold as byproduct - See details in June EIA submission, and GML web site.
I'm sure concentration levels of NaF will vary greatly with depth depending on sample locations, geology etc. due to its water solubility and water run off and nature of the rock (fractures etc). Rivers in the area are relatively high in fluoride content.
We don't need any more discussion on this issue IMO.
ALL above IMO
