Tasman Resources NL Tasman Resources NL Parkinson Dam - - Historical Historical Parkinson Dam • Mid-2005: Outcropping epithermal gold/silver discovered by Tasman following up (PIRSA compiled) calcrete data • Late-2005 and 2006: Drilling (PACE in 2005) locates multiple low grade gold-silver-lead-zinc zones. E.g. – 7.6% Pb, 10.5% Zn, 0.4% Cu, 1.20g/t Au, 120g/t Ag over 1.66m – 3.4g/t Au, 80g/t Ag over 3m • Mid-2007: High grade gold and silver (21g/t Au, 83g/t Ag) over 21m in PD 63 (inc. 9m at 31g/t Au, 152g/t Ag)
