The handful of assays were bookended by 46m at 4.6% copper and 1.2 grams per tonne gold in one hole, and 2.7m at 13.5% copper and 7gpt gold in another.
The true width of the mineralisation in the latest drilling is yet to be confirmed, with the explorer indicating the aim was to drill at right angles to the mineralisation albeit a “number” of holes intersected copper-gold at high angles.
Still, a key point at this stage is the mineralisation being intersected about 350m down plunge.
Drilling from an underground platform at the previously mined project is due to begin later this month while a second rig has arrived at site to accelerate resource drilling.
Green Bay currently hosts a mineral resource of 39.2 million tonnes at 2.1% for 811,000t copper equivalent.
The project was unveiled by Firefly forerunner Auteco last year.
Firefly had cash at the end of October of about A$24 million.
The company’s last fund raising priced new shares at the equivalent of 37.5c.
