    TSC intersects further significant high-grade gold at Creasy 1

    Twenty Seven Co. Limited (ASX: TSC) has announced an encouraging update from the RC drilling at Creasy 1 prospect within the Rover Project in WA’s goldfields.

    The company reported that the assay results for the remaining nine drill-holes from the recent RC drilling campaign at Creasy 1 verify a high-grade shallow gold discovery. The company said that these new results complement the historic results at Creasy 1.

    TSC announced significant new drilling results at Creasy 1 which include 3m @ 20.1g/t Au from 51m; 3m @ 14.8g/t Au from 57m; 15m @ 1.4g/t Au from 18m including 3m @ 3.1g/t Au and 16.8g/t Ag; 9m @ 1.8g/t Au from 57m including 3m @ 4.0 g/t Au; 3m @ 1.5g/t Au from 36m; and 3m @ 3.3g/t Au from 102m.

    The company reported that the high gold and silver grades in hole 19RVRC008 were accompanied by anomalous base metals mineralisation, which indicates a potential VMS signature north of Creasy 1 at the newly named Harmonic prospect.

    TSC said that the gold mineralisation is open in all directions at Creasy 1 and Harmonic. The company said that both prospects will be subject to further RC drilling in order to better define and expand the mineralisation.

    TSC reported that the Creasy 2 assay results and analysis are pending, with reporting expected early in 2020.

    Rover Project

    The Rover project is located ~70km south-east of the Sandstone greenstone belt in WA, which has produced around 1.3Moz of gold.

    Several targets were identified by TSC’s geology team at Rover. Among them, the 12km long shear zone which hosts the Creasy 1 & 2 prospects and several other historic gold anomalies were given priority for immediate exploration.

    The Creasy 1 target comprises gold mineralisation located along the extensive Illara shear zone which forms part of the 20km prospective gold strike.

    A new copper soil anomaly named the “Harmonic Prospect” was recently defined by TSC’s geology team by portable XRF.

    RC drilling campaign at Rover

    The company had recently completed the inaugural reverse circulation (RC) drilling campaign at the Rover project.

    TSC announced that all drill-holes from Creasy 1 have now been assayed, with Creasy 2 assays still outstanding from the laboratory.

    The company reported that at Creasy 1, gold mineralisation has been intersected over 1.2km along strike. TSC said that although there appear to be high grade zones interspersed with lower grade areas, the anomalous gold > 0.1g/t is continuous along strike confirm the high prospectivity the Illara shear zone.

    TSC said that the future drill testing will aim for better definition around high grade zones, down dip and along strike.

    High-grade drill results from Creasy 1

    The company announced that the RC drilling campaign has confirmed the presence of shallow, high-grade gold at the Creasy 1 prospect that materially eclipses all historic drill results.

    TSC said that six holes from the recent drilling have intersected >1g/t gold. This includes 3m @ 20.1g/t Au from 51m (hole 19RVRC006); 3m @ 14.8g/t Au from 57m (hole 19RVRC001); 15m @ 1.4g/t Au from 18m including 3m @ 3.1g/t Au and 16.8g/t Ag (hole 19RVRC008); 9m @ 1.8g/t Au from 57m including 3m @ 4.0 g/t Au (hole 19RVRC007); 3m @ 1.5g/t Au from 36m (hole 19RVRC013); and 3m @ 3.3g/t Au from 102m (hole 19RVRC014).

    The company said that these new results complement the historic results at Creasy 1 which included 6m @ 1.9 g/t Au from 18m; 3m @ 1.9 g/t Au from 53m; 3m @ 1.4 g/t Au from 51m; 3m @ 1.5 g/t Au from 3m; 3m @ 1.3 g/t Au from 18m; and 3m @ 1.3 g/t Au from surface.

    Encouraging results from Harmonic prospect

    The company reported that the RC drilling under the copper soil anomaly named the Harmonic prospect returned highly encouraging gold and silver intersections.

    Highlights include 15m @ 1.4g/t Au, including 3m @ 3.1g/t Au and 16.8g/t Ag (hole 19RVRC008); and 9m @ 1.8g/t Au, including 3m @ 4g/t Au (hole 19RVRC007).

    TSC said that along with the gold, high grade silver and anomalous base metals were also intersected in hole 19RVRC008 which may indicate a volcanic massive sulphide (VMS) signature. The company said that the mineralisation is hosted in weathered mafic schist and metasediments and is open down dip and to the south

    Updates and next steps

    The company announced that following the completion of this campaign, it is now awaiting assays for the RC drilling completed at Creasy 2 to test the 200m long zinc-lead anomaly in soils / rock-chips within a broader copper-gold soil anomaly.

    TSC said that as coincident zinccopper-gold mineralisation is typically common in VMS systems, drilling will test for mineralisation underneath this anomaly.

    The company announced that follow up RC drilling is planned for Q1 2020.

    Management comments

    TSC’s CEO Ian Warland said: “The teams new geological model is paying off, with TSC’s inaugural RC drilling campaign delivering outstanding results at Creasy 1: the discovery of shallow high-grade gold and potentially new VMS style mineralisation.

    The geology team now have substantial gold intersections to build on for follow up RC drilling campaigns in 2020 around Creasy 1, Harmonic and further along the 20km prospective gold strike to Creasy 2 and 3.

    Overall, the key takeaway from the inaugural drilling campaign is the Rover Project’s now demonstrable gold and VMS potential with significant exploration upside moving forward.”
