Object dated: Host Rocks; Age - Ma: 16.75; +0.35; -0.35; Dating method: Ar-Ar; Concentrate: whole rock; Source rock: porphyritic intermediate intrusion; Formal name: intrusive event; Event dated: host rock; Interpretive comment: age of relatively unaltered intrusive rocks indicates the time of emplacement ; Reference: Dow, R.

Qualified comments: |
(Applies to: discovery and development) Discovered in 2000 during gelogical mapping of the area of Arizaro prospect found in 1999; 1100 m of trenching returned an average grade of 0.66 g/t Au and 0.13 % Cu, in a semicircular zone 900 x 70 m. |
