A refresher on Bottletree, but on reflection, BTDD004 might be what DD011 is targeting, not 5 or 6 as suggested in my previous post.

Bottletree Copper Prospect

Bottletree is Superior’s most exciting large-scale copper prospect, located approximately 210 km west of Townsville, Qld and only 5 km south of the Steam Engine Gold Project.

In September 2021, a deep diamond drilling program commenced, which saw the completion of three diamond core holes totalling 2,200m, targeting the untested core of a large, high-order MIMDAS IP chargeability anomaly.

A 2018 hole drilled by Superior identified extensive copper mineralisation, returning 292m @ 0.22% Cu, including 18.7m @ 1.12% Cu (SBTRD006) (refer ASX release 25 October 2018).

On 30 November 2021, Superior announced that drilling at the first two diamond drill holes had identified the presence of extensive porphyry-style copper-gold mineralisation.

The third hole intersected numerous visually-observed copper mineralised vein sets and disseminated copper over the majority of the 659m hole. Strong copper sulphide mineralised vein sets were intersected over an interval of approximately 200m immediately west of the chargeability anomaly. Importantly, veins of quartz-chalcopyrite-molybdenite which resemble Type-B veins in a porphyry system were intersected. Porphyry Type-B veins are a classic indication of a nearby porphyry system.

In January 2022, Superior announced the first assay results from the 2,300m Bottletree drilling program. BTDD001, drilled to 684.6m, intersected extensive disseminated and vein copper-gold-silver mineralisation over variably broad intervals from 132m to 681m, with individual intervals ranging up to 87m. The disseminated zones included numerous zones of high grade, intensely mineralised shear-related chalcopyrite pyrrhotite-quartz veins returning up to 2.79% Cu. Drilling confirmed that the extensive copper mineralisation highlighted by the chargeability anomaly does not represent the main mineralised porphyry stock, but late-stage mineralisation sourced potentially from a large copper-gold porphyry system located nearby and to the west of the anomaly.

FIRST CRITICAL DRILL HOLE: BTDD004:

Significant porphyry-style mineralisation:

632m @ 0.21% Cu, 0.03g/t Au, 0.60ppm Ag, 18.0ppm Mo from 5m below surface, including:
224m @ 0.40% Cu, 0.05g/t Au, 0.90ppm Ag, 3.5ppm Mo from 242m • 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.

..........The mineralisation is more extensive than indicated by the chargeability anomaly and crops out at surface. Although the drilling did not identify the targeted porphyry stock, the amount of copper mineralisation is considerable and is currently observed over at least 750m surface strike, 500m width and 600m vertical extent.

In May 2022, Superior announced assay results from a large multi-element soil geochemistry survey. The results confirmed the Company’s 2021 conclusions by strongly highlighting multiple copper-gold-molybdenum porphyry core targets to the west and southwest of the 2021 area of focus. In addition, porphyry pathfinder elements defined new targets that extend beyond the survey area, significantly expanding Bottletree’s area of interest to 2.5 km by 2.0 km.

In June 2022, Superior announced assay results from the third deep diamond hole completed during 2021, BTDD004. Drilled to 658.9m, it was the third and last hole drilled at Bottletree during the 2021 field season and was designed to test the potential for porphyry copper-gold mineralisation on the western side of a large and intense MIMDAS induced polarisation (IP) chargeability anomaly.

The assays confirmed that a very extensive zone of copper mineralisation was intersected over almost the entire length of the 658.9m hole. Core from BTDD004 showed variably mineralised quartz-chalcopyrite vein sets and disseminated chalcopyrite, including a strongly mineralised 224m interval immediately to the west of the MIMDAS IP anomaly.

Although interpreted to be located some distance from the core of an intrusive porphyry system, the assays returned an impressive main copper zone of 224m @ 0.40% Cu, 0.05g/t Au, 0.9ppm Ag, 3.5ppm Mo (molybdenum) within an overall mineralised zone of 632m @ 0.21% Cu, 0.03g/t Au, 0.60ppm Ag, 18.0ppm Mo.

The results in BTDD004 added to the mineralisation reported earlier from hole BTDD001, collared 500m to the east, which returned an overall intersection of 552.6m @ 0.16% Cu, 0.02g/t Au, 0.7g/t Ag from 132m to the end of hole at 684.6m. BTDD004 has returned the best copper intersection so far at Bottletree and is considered to be indicative of better mineralisation towards the interpreted core of a central porphyry system, west of the 2021 MIMDAS IP anomaly.

2022 drilling program

In June 2022, Superior commenced its 2022 diamond drilling program at Bottletree, comprising an initial eight deep diamond holes for a minimum of 3,700m. The drill holes are targeting the core of at least one large, interpreted Cu-Au-Mo porphyry system that is coincident with a 1.5km x 1km soil copper anomaly and a 1km-wide induced polarisation (IP) chargeability anomaly.

Post-balance date, in August 2022 Superior announced that visual copper mineralisation had been intersected over almost the entire 933.6m Bottletree Hole 5, collared 300m west of the fourth hole. Hole 5 intersected variable zones of visually observed copper-mineralised vein sets and disseminated copper of variable intensities from near surface to end of hole at 933.6m.

The results reinforced the Company’s expectations of the project’s very large size potential, with an extensive dispersion of copper mineralisation. The Bottletree drilling program is expected to continue through to the end of calendar 2022. 9 BTDD005 – 699.9m (left, 708.5m (right) – buck quartz vein with chalcopyrite pyrite-pyrrhotite infill.
