    Sydney - Friday - September 9: (RWE Australian Business News) - Avanco Resources Ltd (AVB) has confirmed the existence of primary copper systems underlying the Antas South and the Antas North deposits at Rio Verde in Brazil.

    Results also indicate the tenor of mineralisation is comparable to large IOCG deposits, typical of the Carajas region.

    Delineation of a possible connection (at depth) between Antas North and Antas South is being investigated as a priority.

    Four deep drillholes have been completed at Antas South.

    Assays for hole ARVD-146 collared 300m northwest of the HGZ confirm a significant primary zone of underlying copper sulphide:

    * 31.00m at 1.40pc copper and 0.10g/t gold from 171.00m

    incl 6.15m at 2.54pc Cu and 0.17g/t Au from 175.00m

    incl 12.20m at 1.89pc Cu and 0.13g/t Au from 189.80m

    incl 2.20m at 5.47% Cu and 0.16g/t Au from 189.80m.

    Two other deep holes at Antas South intersected significant zones of oxide copper mineralisation, including ARVD-139 which also intersected multiple narrow high-grade sulphide lenses, returning:

    * 42.15m at 0.96pc copper from 2.00m

    incl 17.15m at 1.80pc Cu from 27.00m

    incl 1.15m at 9.00pc Cu and 1.12g/t Au from 43.00m

    and 0.85m at 10.60pc Cu and 1.39g/t Au from 114.85m

    and 6.50m at 3.87pc Cu and 0.96g/t Au from 143.00m

    and 3.60m at 5.97pc Cu and 0.81g/t Au from 156.15m.

    Primary sulphide mineralisation has also been confirmed at Antas North (800m from Antas South) where eight diamond drillholes have been completed. Available results include:

    * 47.95m at 1.71pc copper and 0.24g/t gold from 79.60m (AAND-12)

    incl 8.00m at 2.95pc Cu and 0.29g/t Au from 88.00m

    incl 8.00m at 2.49pc Cu and 0.68g/t Au from 114.00m; and

    * 36.00m at 1.39pc copper and 0.27g/t gold from 52.00m (AAND-13)

    incl 5.00m at 3.09pc Cu and 0.39g/t Au from 68.00m

    and 7.60m at 0.84pc Cu from 98.40m

    and 23.15m at 0.69pc Cu from 1.50m.

    Significant intersects have been made along strike at Antas North and it remains open along strike in both directions.

    High concentrations of chalcopyrite in AAND-14, AAND-15 and AAND-19 have been recorded, and favourable results are anticipated.

    Drilling at Antas North continues down plunge and along strike to the southwest, where mineralisation is interpreted to intersect Antas South.

    The interpreted intersection of these trends is supported by the presence of an untested EM (electro-magnetic) anomaly. Follow-up deep drilling at Antas South is expected to resume within the week.
