The Kiskama deposit is inferred to contain 7.7 million tonnes grading 0.25% copper and 0.04% cobalt, with the estimate predominantly based on historical drilling.

Talga's promotion of Kiskama includes a nearby untested conductor discovered this year and the world's need for "conflict free" cobalt supplies.

Talga's recent focus has been on its Vittangi graphite project also in northern Sweden, with prefeasibility work last quarter outlining a staged development costing a total of US$174 million and having a pre-tax net present value of $1 billion and pre-tax internal rate of return of 55%.

Talga, which started the current quarter with A$7.7 million cash, is capitalised at about $86 million.
