In May the explorer announced a giant drilling result of 596m at 0.61% copper and 0.85 grams per tonne gold from just 24m down the hole at the Olgal prospect when using a 0.2% copper cut-off.
The Olgal drilling campaign struck copper-gold intersections in 12 out of the 14 holes and drilling is underway at the Rattata and Pad 48 prospects 3km away.
Highlands aims to drill a $US8-10 million budgeted 16 holes over six target areas by the end of the financial year.
Gooding revealed the Ok Tedi mine, which is 25km north of the project, is a key part of its plans for the project.
"Our strategy for Star Mountains is simple, to identify multiple near surface copper gold deposits of modest scale - 100-200 million tonnes - which can be easily mined and make a meaningful difference to the production options for the existing OK Tedi process plant, which we believe by mid-decade may have spare capacity," he said.
"To this end we will seek to hold discussions with Ok Tedi Mining Limited during 2012-13 on the potential for collaboration and possible studies."
