Geology of the Green Parrot and Reward Silver-Lead Deposits Jervois Range, Northern Territory

The Green Parrot and Reward stratabound silver-lead (copper-zinc) deposits are located in the eastern part of the Arunta Block. At Green Parrot, mineralisation is contained within a north-south striking lode horizon comprised of elongate lenses of massive garnet or calcsilicate-carbonate "lode rocks" with intercalated sericite-biotite schist and laminated biotite-feldspar schist. The "lode rocks" are increasingly calcareous to the west._x000D_
The mineralisation is broadly zoned with an increase in lead content and decreases in copper and silver contents from east to west._x000D_
The principal sulphide minerals are galena, sphalerite and bornite. The Reward deposit lies adjacent to a lens of massive garnet "lode rock" which is contained within garnetiferous sericite-quartz schist. Primary mineralisation consists of galena, chalcopyrite, sphalerite and pyrite. Both deposits are associated with a substantial thickening of the lode horizon which is narrow and discontinuous along strike from the Green Parrot and Reward deposits.
