- Follow-up drilling scheduled for mid-November, including maiden drilling at the Fair Dinkum prospect along strike from Flying Diamond and Lone Wolf deposits in the Lisbon Valley1,2.
CEO, Lyle Thorne commented:
“Our maiden scout drill program at Phoenix has returned some exciting results at Philadelphia, intersecting a shallow mineralised copper zone in the northernmost hole that is open in all directions and at depth. Follow-up drilling is scheduled to commence in mid-November and will include our maiden drill program at the high-priority Fair Dinkum prospect, located directly along strike from known copper deposits in the Lisbon Valley.
Exploration is also underway at our recently acquired Star Range Silver-Antimony Project in Utah, where surface sampling and mapping have commenced ahead of an airborne magnetic survey scheduled for November. With drilling and exploration advancing concurrently across both assets, investors can expect steady, value-driving news flow over the coming months.”
