• The Orchard Tank-Acacia mineralised system comprises a strike length of 400m. The highest grade intersection (WADH012) is also the deepest at 450m below surface, (see long section below).
  
• This is the most extensive zone of zinc-lead-silver-gold-copper mineralisation located to date by De Grey Mining.

Orchard Tank-Acacia Prospect - Metallurgical testing

• Preliminary metallurgical test work was completed in 2007 to determine the optimum grind size, flotation reagent scheme and other process parameters for this mineralisation.
  
• The high metal recoveries (see table below) provide confidence that the type of zinc-silver-lead-gold-(copper) sulphide mineralisation present at Orchard Tank, is suitable for the production of concentrates by standard flotation methods that will be attractive to smelters.
  
• The best concentrate grade and recovery result is given in the following table at a 75µm grind:

*The head grade of the composite sample tested was 7.6% zinc, 260g/t silver, 4.2% lead and approximately 2.1g/t gold.
