North Queensland gold and base metals study

The North Queensland gold and base metals study was conducted in two stages. The first stage covered the Georgetown (Etheridge and Croydon) region and the second stage covered the Charters Towers region.

The reinterpretation of data for these regions involved a desktop analysis using geophysical data acquired through original mapping, followed by limited field checking of significant geological revisions.

Stage 1: Georgetown (November 2002)

The North Queensland Gold and Base Metals Study, Georgetown, is an integrated digital geological information package for the Georgetown area.

The Georgetown area is most prospective for epithermal gold systems, the Broken Hill type base metal mineralisation model, Kidston-Mount Leyshon type gold model, and possibly Carlin style mineralisation.
