Discovery Metals Limited has reported the maiden Mineral Resources estimate at the NE Mango 2 Deposit. NE Mango 2 is located approximately 20 kilometres from the 100% owned Boseto Copper Project, and approximately 5 kilometres along strike from the NE Mango 1 Deposit . It extends over a strike length of approximately 6.6 kilometres.
The Managing Director of Discovery Metals, Brad Sampson commented, “The NE Mango 2 deposit maiden Mineral Resources estimate continues to emphasise the growth potential in the Boseto zone. We will further define the mineralisation in this area and assess its suitability for both open cut and underground mining over the coming months. The existence of a thick high grade zone extending over approximately 1 kilometre should auger well for this mineral resource to become a key feature of the Boseto project expansion story. ”
The estimate has been completed by independent consultants, Xstract Mining Consultants Pty Ltd, and reported in accordance with the guidelines of the 2004 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.
Discovery Metals completed exploration drilling at the NE Mango 2 Prospect during 2012. Drilling comprised 45 drill holes, totalling 6,580 metres. All of these drill holes were reverse circulation (RC) collars with diamond drilling tails (DD) through the mineralisation. All drill holes are located within the area modelled for Mineral Resource estimation.
The mineralised zone at NE Mango 2 has been interpreted between 15 sections spaced approximately 400 metres apart, with one section spaced at 1,000m in the north confirming mineralisation continuity along the total 6.6 kilometre strike length. Copper-silver mineralisation is generally dipping at 80 degrees to the north-west, has been intersected at depths between 30 metres and 250 metres. It occurs as a discrete mineralised layer of approximately 2 metres to 16 metres in thickness, with a general thickening in the central portion of the Prospect over a strike length of 1,000 metres.
Approximately 30 metres of unconsolidated Kalahari Sands and calcrete overlay the mineralisation at NE Mango 2, with the top of the sulphide zone occurring at vertical depths of approximately 100 metres. For comparison, at the Zeta open pit sand cover typically is less than 10 metres and sulphide mineralisation is generally within 35 metres of the surface.
The sulphide copper mineralisation at NE Mango 2 is primarily chalcopyrite with lesser amounts of bornite and chalcocite.
The copper-silver mineralisation remains open at depth and the presence of a thick central core of copper-silver mineralisation may create opportunities for open pit and underground mining.
Further drilling is required to understand the nature of the copper-silver mineralisation in the oxidised zone which has not been included in this Mineral Resources estimate. At the nearby Zeta and Plutus Deposits the oxide and transitional zones contain economic copper-silver mineralisation and potential for this exists at NE Mango 2.
Work continues to assess the full potential of the NE Mango 2 Prospect with the copper-silver mineralised zone showing potential for open pit and underground mining.
