President and CEO Brooke Macdonald said:

"Newcrest is one of the largest gold mining companies in the world, operating mines in Australia, Papua New Guinea, and Canada. They spent over US$2.6 million on the Project, in excess of their US$1.1 million work commitment, and have been an excellent partner.

“As reported in Cornerstone’s news release 22-11 dated April 28, 2022, after drilling three reverse circulation holes no significant assays were reported.

“As per the terms of our Agreement, Newcrest will wind down activities and leave the concessions in good standing for one year, while Cornerstone determines if we can attract another funding partner to reactivate the Project.”
