Geological ages: Late Paleoproterozoic (host rocks)
Late Paleoproterozoic (mineralization)
Host rocks: (1) metamorphic; metasedimentary schist (albitized domain)
Metallogenic signatures: Fe-Cu-Au-F-P-V-Zn-Se-Mo-Ag-Te-Ba-REE-Pb-Bi
Alteration signatures: albitization; What was altered: sedimentary rocks; Component: post-metamorphic regional alteration
phyllitization; Component: high grade Cu-Au zones
Radiometric ages: Object dated: host rocks; Age - Ma: 1,703; +6; -6; Dating method: U-Pb Shrimp; Concentrate: zircon; Source rock: Tuff; Event dated: host rock; Interpretive comment: Same age as parts of the Willyama Supergroup, Broken Hill District and Olary Domain

Object dated: alteration signature; Age - Ma: 1,630; Dating method: U-Pb Shrimp; Concentrate: monazite; Source rock: albitite; Event dated: alteration; Interpretive comment: This is very approximate, confirming pre-1600 Ma age of regional albitization; Reference: Teale, G.
