Bonya, Northern Territory

Copper, lead, zinc, silver, gold, bismuth and PGE’s

Rox is exploring the Bonya tenement for copper, lead, zinc, silver, gold, bismuth and PGE mineralisation under a joint venture with Arafura Resources.

Highlights:

  • High Grade Copper Intersected in drilling:
    • 38m @ 4.4%Cu
    • 13m @ 5.4% Cu
    • 3m @ 13.4% Cu
  • Geochemical sampling identified several anomalous areas with outcropping secondary copper mineralisation
  • Mineralisation style is the same as the adjacent Jervois copper deposit
  • Rox holds a 51% project interest and Arafura holds 49%

Exploration

Late in 2014 Rox discovered high grade copper mineralisation at the Bonya Mine Prospect. The drilling defined massive copper sulphide mineralisation over substantial  widths and over a vertical interval of at least 100m.

Historic Mining Activities

Assessment of historic mining activities at the old Bonya Copper mine indicates the potential for depth extensions to the outcropping mineralisation, which has never been previously drill tested. Both the Bonya and the near by Jervois copper deposits (which has a current JORC Mineral Resource of 25.2Mt @ 1.1% Cu, 23.4 g/t Ag) are in an interpreted high metamorphic grade Volcanogenic Massive Sulphide (VMS) geological setting similar to other areas such as Mount Hardy in the Northern Territory and of a similar deposit type to those found in the Doolgunna district in Western Australia, which hosts Sandfire’s DeGrussa deposit. There are walk up drill targets at the old Bonya Mine prospect and Rox has identified outcropping oxide copper mineralisation grading up to 33% copper, 55 g/t silver and 0.5 g/t gold.

Agreement Structure and Commercial Terms

Under the terms of the agreement, Rox has eaned a 51% interest in the copper, lead, zinc, silver, gold, bismuth and PGE mineral rights. Arafura retains a 49% interest in these minerals, and 100% of all other mineral rights over the tenement, EL29701.
