From the Management discussion and analysis - Inv. in CL ltd24 Jun 2021 11:48
"Included in marketable securities is the fair value of common shares held in private companies of $1,001,007 (January 31, 2021 - $1,001,007), most of which represents the Company’s holding in Cornish Lithium. "
Given CL's recent capital raise was at a price around double that of the previous raise, I think that CUSN's holding in CL will have risen in value to around $2m. A useful investment, which CUSN might or might not wish to realise next year when CL floats on AIM.
