WMC Resources Ltd discovered Nifty in 1980 by using regional ironstone sampling and reconnaissance geology. Malachite staining of anoutcrop and Cu-anomalous ironstones from dune swale reconnaissance sampling were the initial indicators (Figure 2). This was followed by lag sampling on a 500 x 50 m grid that detected a 2.5 x 1.5 km Cu-Pb anomaly. Secondary Cu mineralization was intersected in percussion drilling in mid-1981, with high-grade primary ore (20.8 m at 3.8% Cu) discovered in 1983.From: [url]http://crcleme.org.au/RegExpOre/Nifty.pdf[/url]
