From the Quarterly:
GEOLOGY AND EXPLORATION
2nd paragraph:
"The Company is looking at optimising its holdings at Charters Towers with the aim of focusing on the core gold mining operations of the Charters Towers goldfield surrounding the resources and reserves already defined. Rather than looking for new discoveries regionally further afield. The Charters Towers project can provide a long and profitable mine life for the Company, shareholders and the local community."

Tenement EPM 16979 has been relinquished.

So, IMO, CTO can no longer afford to maintain the exploration permits so we have to give them up.
Not sure what area this tenement is in, but the are giving the farm away.
