The diamond drilling intersected the mineralisation between 10-75m below surface with peak grades up to 1.7% copper, 0.3% nickel and 0.09% cobalt.
The four lenses ranged from 3.5-26.2m thick, with the best and thickest being the most shallow: 26.2m grading 0.5% copper, 0.2% nickel and 0.06% cobalt.
In the field, ahead of a 4-5 week infill and extensional RC drilling program focused on the Central zone, the company is also undertaking downhole electromagnetic surveys to better understand the extend of the conductor plates at depth.
A gravity survey is also due to begin to identify discrete intrusions within the larger Mt Venn and Eastern Mafic complexes, and should cover about 70% of the Yamarna project.
The exploration program is split between focusing on the...
