Twenty Seven Co hits shallow high-grade gold in inaugural Creasy 1 drilling

The results of up to 3 metres at 20.1 g/t have exceeded expectations and are higher than historical economic gold intercepts.

Twenty Seven Co Ltd (ASX:TSC) has hit shallow, high-grade gold of up to 3 metres at 20.1 g/t from 51 metres in its’ inaugural reverse circulation (RC) drilling at Creasy 1 prospect within the Rover Project in WA’s Goldfields.

The results, which also include 3 metres at 14.8 g/t from 57 metres, confirm the presence of shallow, high-grade gold at Creasy 1 that materially eclipses all historical drill results.

Assays for six out of 15 planned holes have been received with all returning anomalous gold results of at least 0.1 g/t.

“Exceeds expectations”

CEO Ian Warland said: “The geology team’s efforts in identifying priority gold drill targets at the Creasy 1 prospect have delivered an outstanding result that well exceeds expectations.

“Notably, the high grades and shallow depth are exceptional outcomes.”

This encouraging start to drilling comes at a time when there is a resurgence in the Central Yilgarn following recent discoveries by St George Mining Ltd (ASX:SGQ), Spectrum Minerals Ltd (ASX:SPX) and Cobre Group.

Drilling is continuing on schedule at Creasy 1 and further assay results are expected as they are processed by the laboratory.

The holes are being drilled along the Illara shear zone over a strike length of about 1-kilometre at 200 to 400-metre spacing.

Exploration upside

Drilling indicates that the Illara shear is zone is mineralised over an extensive length, which delivers further exploration upside to the Rover Project.

Rover Project relative to greenstone belt and select peers’ operations.

After the Creasy 1 program, the rig will move along strike to Creasy 2 where a volcanic massive sulphide (VMS) target is to be tested.

 Warland said: “This is a very exciting and transformative development for TSC, more so, as we are only part way through the current drilling campaign.

“Overall, we are extremely pleased with the successful start to the current RC drilling campaign and look forward to announcing further results as they come to hand.”

Priority areas for drilling are along the 20-kilometre gold strike which is part of the Maynard Hills greenstone belt, on the eastern boundary.

VMS targets at Creasy 2

At Creasy 1 the targets are shallow historic economic gold intercepts while at Creasy 2, further southwest along the strike, the program is targeting new gold/VMS targets identified from analysing aero-magnetics data.

TSC’s geology team continues to drill test the Illara shear zone, including the coherent copper anomaly found in XRF soil sampling north of Creasy 1.

This anomaly within soil samples across four lines covers around 180 metres of strike.

Further, the anomaly appears to be related to BIF and mafic schist just west of the sheared quartzite contact and north of the major structural offset.

The copper anomaly proximal to the Illara shear contact will be tested in the current RC drilling program.

Work agenda

TSC has a full agenda moving forward including:

  • Ongoing RC drilling at the Creasy 1 gold prospect with further assays of 3-metre composite samples expected shortly; 
  • RC drilling will move along strike to Creasy 2 to test the 200-metre-long zinc-lead anomaly in soils/rock-chips within a broader copper-gold soil anomaly. As coincident zinc-copper-gold mineralisation is typically common in VMS systems, drilling will test for mineralisation underneath this system; and
  • Follow-up RC drilling is planned for Q1 2020.

The Rover Project is 140 kilometres west of Leonora in a base metals and gold mineral-rich area associated with mafic and ultramafic rocks.
