Exploring the Fraser Range: Geological Map Insights and Drilling Program Results
The Fraser Range, located in southern Western Australia, is a region of significant geological interest due to its potential for hosting various mineral deposits. The Geological Survey of Western Australia (GSWA) has extensively mapped this area, providing valuable insights into its geological framework. These maps highlight several prospects, including those with potential for copper, gold, and base metals.
One of the key features of the Fraser Range is its association with Iron Oxide Copper Gold (IOCG) and Broken Hill Type (BHT) mineral systems. These systems are characterized by specific geological signatures, such as high magnetic anomalies and gravity responses, which are indicative of underlying mineralization. The GSWA's geological maps have been instrumental in identifying these targets, guiding exploration efforts in the region.
In addition to IOCG and BHT targets, the Fraser Range is also noted for its potential to host other critical minerals. Recent studies have indicated the presence of rare earth elements (REEs), titanium dioxide (TiO₂), and scandium in the near-surface saprolite layers. These findings open up new avenues for exploration, emphasizing the region's diverse mineral potential.
The geological mapping efforts by GSWA continue to evolve, incorporating advanced technologies and methodologies. This ongoing work ensures that the geological understanding of the Fraser Range remains current, supporting sustainable and efficient exploration activities.
