The geochemical signature is akin to Stage II mineralization in the Veta Sur system, but also exhibits highly anomalous vanadium contents, similar to bonanza grade mineralization at the Porgera gold mine in Papua New Guinea and elsewhere.
Pinguro Vein Target (Figure 1)
The Pinguro prospect is located in a 1 square-kilometre area containing multiple families of auriferous veins, outlined by soil geochemical work, geological mapping and near-surface rock-chip sampling. Two orientations of vein sets have been recognized, north-northwest-striking and east-northeast-striking and moderately southwest-dipping, the latter vein sets with potential strike lengths of over 300 metres, vertical extents of potentially more than 300 metres and open in all directions. Country rocks are mainly Cretaceous metabasalts and metasediments locally intruded by andesitic bodies.
Limited rock-chip sampling indicates that both vein orientations may exhibit high-grade, gold-silver mineralization. Highlights of vein channel sampling are included in Table II and outlined in Figure 1 along with gold-anomalous soil samples.
