Cyprium Metals (ASX:CYM) said it completed the first pass review of exploration data received from IGO (ASX:IGO) for around 2,000 square kilometers of reacquired tenements adjacent to the Nifty copper complex and Maroochydore copper-cobalt project in Western Australia, according to a Tuesday Australian bourse filing.

The tenements were previously subject to a joint venture and farm-in agreement with IGO, which had identified numerous targets.

It identified potential to extend known copper mineralization at the Rainbow prospect, and a drill program to confirm and extend mineralization is being designed, per the filing.
