Superior Resources (ASX: SPQ) has reported a ‘significant’ 632m copper intersection from diamond drilling at the Bottletree prospect within its Greenvale Project in Queensland.
Hole BTDD004 delivered mineralisation totalling 632m @ 0.21% Cu, 0.03g/t Au, 0.60ppm Ag, 18.0ppm Mo from 5m below surface.
Within this, key porphyry-style mineralisation included:
- 224m @ 0.40% Cu, 0.05g/t Au, 0.90ppm Ag, 3.5ppm Mo from 242m, incl
- 2m @ 1.01% Cu, 0.24g/t Au, 2.7ppm Ag, 9.5ppm Mo from 337m
- 103m @ 0.53% Cu, 0.05g/t Au, 1.4ppm Ag, 3.3ppm Mo from 363m
- 1m @ 5.25% Cu, 0.31g/t Au, 10.7g/t Ag, 1.5ppm Mo from 363m
- 12m @ 1.01% Cu, 0.07g/t Au, 2.2ppm Ag, 1.9ppm Mo from 363m
- 15m @ 1.19% Cu, 0.15g/t Au, 3.6ppm Ag, 1.9ppm Mo from 451m
- 3m @ 1.12% Cu, 0.14g/t Au, 4.8ppm Ag, 2.1ppm Mo from 631m
Commenting on the results, Superior Resources Managing Director Peter Hwang said: “The better-than-expected results returned from BTDD004 are impressive, particularly considering the mineralisation is thought to be some distance away from the interpreted porphyry core where higher grades are expected. To have intersected such a large interval of significant grade copper at this distal part of the interpreted system, provides us with further confidence that we are dealing with a very large-scale copper-gold system.

The grades and the very large intersectional widths in hole 4 are similar to, or significantly better than those in many recent porphyry copper discoveries in South America, British Columbia and Australia.
This year’s drilling program is on track to commence shortly with the first holes targeting the highest priority interpreted porphyry core, west of BTDD004. With two of three holes from last year’s program confirming very broad intervals of near-surface copper mineralisation, we will also be building on Bottletree’s near-surface, large tonnage potential.
2022 promises to be an exciting year for Superior and we expect multiple catalysts from the activities and expected results ahead of us at Bottletree and our other copper and gold prospects.”
The company also notes that remodelling of MIMDAS IP geophysical data has highlighted a 1km-wide zone located west of 2021 drilling, which is interpreted as potential mineralisation associated with the core(s) of one or multiple porphyry zones.
In addition, these results along with data gathered from IP remodelling have identified a total of 6 high-priority targets with a very large IP chargeability, located 700m to the southeast of drill hole BTDD004. This is coincident with a high priority soil geochemistry target.
Map of the Greenvale Project displaying key prospectsThe 100%-owned Greenvale Project is located approximately 210km west of Townsville in Northern Queensland, and covers a region of volcanic and intrusive rocks. The company notes that the geology is similar to the porphyry copper belt located in New South Wales that hosts the large Cadia and NorthParkes porphyry copper mines.
With the current diamond drilling program ongoing, Superior Resources reports that it will move forward with a multi-stage drilling program to target a potential porphyry core located west of existing near-surface copper mineralisation, with drilling to commence in the coming week.
