Yarram Park Project
COPPER-GOLD EXPLORATION
PROJECT OVERVIEW
The Yarram Park Project, comprising exploration licences EL5478, EL7628 and EL7920, overlies the Bunnugal Belt of the Cambrian Stavely Volcanic Arc, which is considered highly prospective for intrusive related porphyry copper-gold.
QUICK LINKS
REGIONAL GEOLOGY
The Yarram Park Project is located within an area where interpretation of regional aeromagnetic data has identified the presence of an offset portion of the Bunnagul Belt (another volcanic belt located to the west of the Stavely Belt), beneath the Quaternary cover. Both the Stavely Belt and the Bunnagul Belt are considered to be highly prospective for intrusive-related porphyry copper-gold and diatreme-hosted gold mineralisation. Maiden drilling in 2017 confirmed the existence of the right host rocks with the presence of distal porphyry-style alteration.
TOORA WEST
Drilling at the Toora West prospect on the Yarram Park Project confirmed the presence of porphyry-style copper and molybdenum mineralisation as well as a later phase of high-grade gold mineralisation. Exploration at Toora West was successful in identifying porphyry-style Cu-Mo-Au mineralisation beneath 30 to 40m of transported cover. Examination of the aircore chips and diamond core has led to the conclusion that while the abundance of intrusion types suggests Toora West as an interesting porphyry-related magmatic system, none of the intrusions contain anything other than a simple and single porphyry Cu-Au style episode of mineralisation. It has been concluded that the Cu-Au vein mineralisation in the drill holes is more typical of veins hosted within wall rocks and is likely related to deeper porphyry source rocks.
