Twenty Seven Co has defined three broad areas of anomalous gold mineralisation at its Yarbu gold project north of Southern Cross in Western Australia, with one zone coming in it at a hefty 1.9km-by-1.4km. The company plans to drill-test the new targets located along the Marda-Diemals Greenstone Belt that also hosts Ramelius Resources’ 280,000-ounce Marda gold project to the south.

Twenty Seven Co has defined three broad areas of anomalous gold mineralisation with an extensive auger sampling campaign at its Yarbu gold project north of Southern Cross in Western Australia. The company plans to drill-test the new targets, including one hefty 1.9km-by-1.4km area, located along the Marda-Diemals Greenstone Belt that also hosts Ramelius Resources’ 280,000-ounce Marda gold project to the south.

The results from 662 auger holes to an average 1.46m depth, said to be the most comprehensive geochemical sampling at Yarbu to date, have helped Twenty Seven Co define several wide-spaced geochemical anomalies with gold values going as high as 164 parts per billion at the 1.9km-by-1.4km “Area 2” zone in the central part of the tenure.

Management says that Area 2, in conjunction with the nearby Area 3 zone, lie adjacent to the historical Clampton North prospect also identified via a 1,000m-by-200m auger gold anomaly.

The mineralisation in the adjacent tenement is believed by the company to be associated with the Area 2 anomaly.

Intriguingly, significant historical intercepts including 16m at 3.09 grams per tonne gold from 88m with a richer interval of 10m at 4.44g/t gold from 90m are also reported to the south of Area 3 in an adjoining licence.

At the Area 1 zone to the north, a gold-in-soil anomaly covering about 2km-by-1km is reported to be associated with zinc and molybdenum.

Twenty Seven Co’s CEO Simon Phillips said: "We are delighted with the outcomes from our auger drilling campaign, the first large-scale regional sampling program to be undertaken within the Yarbu project area. Importantly, the program has achieved its main objective, which was to confirm gold mineralisation across key areas of the Yarbu project.”

“Encouragingly, the anomalism identified within Yarbu highlights the typical geochemical response from gold deposits in the region, such as being elevated in lead and to a lesser extent zinc, so we are looking forward to further investigating this potential over the coming months.”

Twenty Seven Co is now planning more closely spaced auger or air-core drilling to pinpoint targets for more advanced follow-up testing.

The 100 per cent owned Yarbu tenure lies adjacent to Ramelius Resources’ Marda ground where the mid-tier Australian gold miner is mining 1.8-to-2 g/t dirt for trucking to its 2.7 million tonne per annum Edna May plant near Westonia.

Yarbu forms part of the company’s gold exploration portfolio in Western Australia which combined covers some 784 square kilometres of land.

Twenty Seven Co recently delivered a maiden resource of nearly 50,000 ounces gold and 90,000 ounces silver at its Mt Dimer project about 80km south-east of Yarbu.

The resource is said to be open to the south and down dip with strong potential to extend the mineralisation along strike.

The company is also exploring its Rover project south-east of Sandstone where successive drilling and soil sampling programs have produced a string of strong gold results along parallel, linear regional greenstone structures between Sandstone and Menzies to the south.

Drilling at the Creasy 1 prospect returned 15m at 3.8g/t gold from 49m, including 1m at 54g/t gold.

At the Harmonic prospect near-surface hits include 17m at 1g/t gold, with a richer interval of 1m at 3.7g/t gold.

Follow-up drilling of high priority targets at Rover is on the cards in the second half of the year.
