Note: photographs of specimens in this section of tiger iron labeled from Perenjori Shire are more likely to have come from Marra Mamba, or nearby in the Pilbara. Several small iron ore mines and prospects do occur east of Perenjori,which are based on Banded Iron Formations, but the region lacks asbestos needed for the tiger eye component of tiger iron. Geologists I have talked to from mines in the region agree, and the writer has never come across specimens pictured while fossicking in the area.
The Shire of Perenjori is 360 kilometres north of Perth, covers 8 313 square kilometres, with a population of 524. Perenjori itself is the only town in the shire. The western portion of the shire is flat wheatfields, while the eastern portion is beyond the agricultural area in pastoral land, although a lot of the stations in this area are now conservation reserves. The economy is based on cereal growing/sheep and mining.
Attractions include a Monsignor John Hawes historic church in the town, and tourist drives. As Perenjori sits between the northern heathlands region, and pastoral areas it is a good base for wildflower viewing in spring.
The eastern portion of the shire contains the Karrara iron ore mine, the Warriedar copper mine, the Kooloonooka iron ore mine, and historically the Rothsay gold/copper mine, and Mount Mulgine Tungsten mine. There are also several historic gold mines in the area. The Rothsay beryl mine was a popular beryl and apatite fossicking location, although specimens are likely to only be seen in local collections. The writer's family once owned Karara Station, now a conservation reserve.
