The drilling at the Lantern prospect hit "disseminated" and "blebby" sulphides in the first two holes over widths of 16-23m, with the third hole of a three-hole program underway.
One of the completed holes was targeted underneath a previous drilled RC hole that hit nickel and copper, while the other completed hole (that also hit sulphides), "did not identify a conductor able to explain the responses observed from both surface moving loop and fixed loop EM surveys".
Further geophysics will be undertaken.
Assays are awaited.
The third hole is prefaced on a structural target.
Lantern is located between IGO's Nova mine and Legend Mining's Mawson discovery.
