Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may delineate adjacent plus regionally distributed zones where the deformation event responsible for mineralization is locally present at sufficient intensity to form ore. This would allow targeted deep drilling in ground with no ore close to the surface saving millions in drilling costs and dramatically increasing the financial viability of this industry.

瞄准盲目矿化是澳大利亚矿业面临的最大问题。本项目开发的建模将整合变形、流体和化学过程，并提供一种了解变形分区的手段，这种分区将后生矿石定位在区域上以及沿大规模构造的沿着部分定位。将其应用于已知的矿床可以描绘出相邻的加上区域分布的区域，其中负责矿化的变形事件以足够的强度局部存在以形成矿石。这将允许有针对性地在地面进行深层钻探，而没有矿石接近地表，节省数百万美元的钻探成本，并大大提高该行业的财务可行性。
