Avanco Resources intersects 27.70m at 5.96% copper and 2.80g/t gold at Rio Verde

Avanco Resources’ (ASX:AVB) deep drilling program at its Rio Verde Copper Project in Brazil continues to intersect substantial widths of ore grade mineralisation at Antas North.

Some holes contain significant gold values, with highlights including 27.70 metres at 5.96% copper and 2.80 grams per tonne (g/t) of gold from 53.15 metres and 35.60 metres at 3.67% copper and 0.22g/t gold from 153 metres.

Meanwhile, at Antas South the latest drilling results include 4.70 metres at 9.31% copper from 48 metres, including 1.70 metres at 16.04% copper from 51 metres, and have confirmed the strike length of the Rio Verde High Grade Zone to exceed 520 cubic metres and to remain open on strike.

Earlier deeper drilling at Antas South intersected a 31 metre wide ore zone, which returned results of 1.40% copper and 0.1g/t gold from 171 metres.

Mineralisation intersected to date is interpreted to represent a thick sub-vertical ore body containing zones of high grade massive sulphides.

The latest results show that deeper drilling at Antas North is intersecting increasing lengths of primary sulphide mineralisation, and supports the potential presence of a large primary iron oxide copper gold (IOCG) system.

Drilling will continue to follow mineralisation down plunge and along strike to the south-west. Avanco predicts this trend could intersect the Antas South trend at depth. Infill drilling has begun, to enable resource estimation.

To enhance the targeting of primary IOCG sulphides, a helicopter VTEM (Electromagnetic) survey will begin in the coming weeks.

The survey will cover the key Rio Verde trend and test for deep primary sulphides at Antas North, definition/continuation of sulphide mineralisation below Antas South, and primary sulphide targets along the Rio Verde trend.

Avanco's highly prospective Rio Verde Project comprises seven copper prospects; Agua Boa, Antas North, Antas South (host to the High Grade Zone), Capivara, Clovis, Lazinho and Paulinho.
