Tennant Minerals Limited (ASX: TMS), is excited to announce a spectacular, true-width intersection of high-grade copper and gold from BBDD00181, the first diamond drillhole of the recently completed Stage 2 drilling program at the Bluebird discovery (see intersection on longitudinal projection, Figure 1 below).
- Diamond drillhole BBDD0018 has produced a spectacular, true-width, intersection of high- grade copper and gold at the Bluebird discovery, 40km east of Tennant Creek in the NT:
- 30.5m @ 6.2% Cu and 6.8 g/t Au from 153.6m (downhole),
including 17.8m @ 5.2% Cu and 11.5 g/t Au from 153.6m, and,
including 16.1m @ 10.5% Cu and 0.44 g/t Au from 164.9m.
- 30.5m @ 6.2% Cu and 6.8 g/t Au from 153.6m (downhole),

- This spectacular gold and copper-sulphide intersection occurs at a similar depth to previous, exceptional, copper-gold intersections at Bluebird, including:
- BBDD0012: 63m @ 2.1% Cu, 4.6 g/t Au from 153m incl. 40m @ 3.0% Cu, 7.3 g/t Au2
- BBDD0007: 50m @ 2.7% Cu, 0.52 g/t Au from 158m incl. 24m @ 5.0% Cu, 1.0 g/t Au3
- BBDD0013: 40m @ 2.6% Cu, 1.3 g/t Au from 131m incl. 24.5m @ 3.9% Cu, 0.45 g/t Au4
- BBDD-2: 20m @ 0.61% Cu, 8.17 g/t Au, from 157m incl. 4m @ 0.66% Cu, 37.9 g/t Au3
- BBDD0012: 63m @ 2.1% Cu, 4.6 g/t Au from 153m incl. 40m @ 3.0% Cu, 7.3 g/t Au2
- These intersections occur within a thick and shallow-plunging dilational zone which is open along strike to the east and especially to the west, where it becomes shallower.
- New drilling is planned to test shallow extensions of this exceptionally thick and high-grade copper-gold zone, as well as at depth where results are pending from a further five drillholes, including intersections of thick and intense copper mineralisation (descriptions – Appendix 1).
- Drilling will also test other priority targets within the 2.5km Bluebird-Perseverance Corridor.
Tennant Minerals Chairman Matthew Driscoll commented:
“This latest drill-hit from Bluebird is truly spectacular and includes a thick and high-grade gold zone of over 11 grams per tonne, as well as a massive copper-sulphide zone grading over 10 percent copper.
“Drilling is already planned to extend this remarkable new discovery, which lies under shallow cover to the east of the Tennant Creek Mineral Field and continues to grow – in all directions.”
“Theresultsareanotherkeystepinour strategy to identify multiple, multi-million tonne, high-grade copper- gold deposits within the Barkly Tenements, where we aim to establish a stand-alone copper-gold project.”

The spectacular BBDD0018 diamond drilling intersection of:
- 30.5m @ 6.2% Cu and 6.8 g/t Au from 153.6m (downhole),
includes a high-grade gold zone of 17.8m @ 11.5 g/t Au, 5.2% Cu from 153.6m which extends from the faulted hanging wall side of the brecciated ironstone. The gold zone overlaps with the high-grade copper zone of 16.1m @ 10.5% Cu from 164.9m, which includes massive copper-sulphides (chalcopyrite and chalcocite – see descriptions, Appendix 1) (see Image 1). The copper zone extends to the footwall side of this thick, true-width intersection (see Table 1 for all significant intersections and Table 2 for drilling details).
This new intersection extends the shallow easterly plunging dilational zone to the west, where it becomes shallower and remains open. This zone also includes the extraordinary results from BBDD0012 of 63.0m @ 2.1% Cu and 4.6 g/t Au2 from 153.0m and BBDD00091, which intersected 50m @ 2.7% Cu and 0.52 g/t Au3 from 158m, which occur at a similar depth below surface (see Figure 1).
Other key intersections within this zone include BBDD0013, which intersected 40m @ 2.6% Cu and 1.34g/t Au4 from 131m, and the previous exceptionally high-grade gold intersection in BBDD-2 of 20m @ 0.61% Cu and 8.17 g/t Au3, from 157m (Figure 1).
