Highlands Pacific Ltd has received further evidence of extensive mineralisation at the remote Star Mountains project in PNG, with recent assay results confirming long high grade copper intercepts.
The company reported to the ASX that final assay results from the third hole drilled at the Fune prospect have been received, identifying significant mineralised zones at depth, including the following intercepts at 0.1% Cu cut off:
• 50.0m @ 0.32% Cu, 0.09g/t Au, from surface, including: • 8.0m @ 0.63% Cu, 0.33g/t Au, from surface
• 67.0m @ 0.41% Cu, 0.13g/t Au, from 82m, including:
• 8.9m @ 0.87% Cu, 0.28g/t Au, from 114m
• 10.0m @ 0.87% Cu, 0.30g/t, from 137m
• 158m @ 0.45% Cu, 0.13g/t Au, from 198m, including:
• 6.4m @ 1.12% Cu, 0.28g/t Au, from 198m
• 2.0m @ 0.57% Cu, 0.28g/t Au, from 208m
• 2.0m @ 0.65% Cu, 0.07g/t Au, from 278m
• 6.0m @ 1.09% Cu, 0.20g/t Au, from 234m
• 42.0m @ 0.87% Cu, 0.31g/t Au, from 308m
The fourth hole drilled at Fune, to investigate a conductive anomaly identified through geophysics and airborne surveys, was completed on August 2, reaching 907.8 metres. Core logging revealed skarn and porphyry mineralisation between 136 metres and 390 metres. Assay results for the hole are expected in September.
Drilling will now resume at the Olgal prospect to the south east of previous drilling, where a number of holes were drilled in the 2015 campaign, revealing extended zones of mineralisation. A drill pad is now being prepared for hole 21 at Olgal, which is to be drilled to 600 metres, targeting a potential skarn zone. This is expected to be the final hole in the current campaign.
Highlands CEO Craig Lennon said the latest results provided further information to enhance understanding of the Star Mountains geology.
“These are great results, again confirming wide mineralised zones. This drilling information continues to support our expectation that there is potential for a large copper porphyry system at the Star Mountains that could support a significant mining operation. Each piece of drilling data helps us to understand the geology and allows us to refine our exploration efforts,” he said.
Highlands and Anglo American commenced the current exploration drilling program in October 2016. Six holes have now been drilled and completed for a total of 5,182.6 metres.
