Ironbark Zinc has decided to forego its option to acquire a 70% interest in the Daltons and Bamboo Creek projects.

The projects will revert to the exclusive ownership of Sorrento Resources.

Ironbark has chosen to place its resources and efforts into the newly acquired Simon-Anderson projects located in Mt Isa, Queensland.

"Ironbark has chosen to focus its efforts in the next 6-months on exploring our newly acquired Simon-Anderson Projects in Mt Isa, Queensland and finding a pathway forward at Citronen in Greenland," commented Michael Jardine, managing director of Ironbark Zinc.
