Tasman Resources NL<strong>Parkinson</strong> <strong>Dam</strong> – Local Geology
Tasman Resources NL<strong>Parkinson</strong> <strong>Dam</strong> - Historical• Mid-2005: Outcropping epithermal gold/silver discovered byTasman following up (PIR<strong>SA</strong> compiled) calcrete data• Late-2005 <strong>and</strong> 2006: Drilling (PACE in 2005) locates multiplelow grade gold-silver-lead-zinc zones. E.g.– 7.6% Pb, 10.5% Zn, 0.4% Cu, 1.20g/t Au, 120g/t Ag over1.66m– 3.4g/t Au, 80g/t Ag over 3m• Mid-2007: High grade gold <strong>and</strong> silver (21g/t Au, 83g/t Ag)over 21m in PD 63 (inc. 9m at 31g/t Au, 152g/t Ag)
