A large, multi-element geochem survey for Queensland focussed Superior Resources has delivered results from its wholly-owned Bottletree copper prospect. Multiple, strong targets for a planned aggressive drilling program into the cores of at least three porphyry intrusions have been identified as well as several large zones of copper mineralisation that will feel the pressure of the drill bit.
The multi-element survey was conducted around a large 1.3 square kilometre interpreted, largely buried, intrusive complex it described as an intrusion ring and picked up copper, gold and molybdenum anomalies. The mineralisation remains open to the west and southwest of the survey area with Superior saying the results significantly expanded the area of potential at Bottletree.
The survey picked up 1517 samples from a 2.0 kilometre x 1.8km grid at 50m sample and line spacings with the aim of defining the core of a mineralised porphyry system and planning a subsequent drilling program.
At least six target zones have been identified with three or more buried copper, gold and molybdenum porphyries as highest priority drilling objectives.
It also picked up porphyry intrusions and copper mineralisation outside of the intrusion ring with three bore holes showing copper outside and some way from the interpreted porphyry centre.
Superior Resources Managing Director, Peter Hwang said: “This is a significant boost to what is already a robust and very exciting copper project.”
“The results not only validate our expectations of a buried mineralised porphyry lying to the west of the IP [induced polarity] chargeability anomaly, but they have also highlighted several other unexpected potential porphyry intrusion centres.”
Hwang says of particular note are two new strongly anomalous zones: one about 700m to the southeast of the IP anomaly coinciding with a “very interesting” chargeability feature, originally identified during the 2018 IP survey with another extending to and remaining open on the western flank of Bottletree.
According to Hwang, the soils also indicate the copper mineralisation at the IP anomaly in 2021 is widely mineralised over a large area however is some distance from the main porphyry mineralisation and would be secondary targets.
Frontier has secured its drilling contractors and pending weather conditions and site preparation, will be commencing an aggressive and large drilling program as soon as practicable.
The Bottletree drilling will be in addition to the resource expansion program at Steam Engine, 200km inland from Townsville and associated programs planned for three other Greenvale porphyry copper-gold prospects.
