Mineral Rangahau holds ground in two areas with potential for northward dipping gold ore-shoots in the identical geological setting to those recently discovered by Santana Minerals. The crustal kilometer- scale fault separating Otago Schist of Texture Zones 3 and 4 that controls the location of the Santana discovery also controls the location of a 10-million oz resource (Macraes Mine owned by Oceana Gold). The 19sqkm Capburn area lies 20 km east of Macraes while the second 45sqkm RaggedyRange area lies 30 km east of the Santana discoveries.
At Capburn during the the 2020-21 summer eight holes drilled on the south side of the fault revealed a channel in the schist with anomalous gold arsenic and antimony 1.5km wide by 290m thick extending over 1km. Fluid flow was controlled by permeable schist foliation and likely extends many more kilometres downdip paralleling the foliation under and parallel to the controlling crust-scale fault.
Eighty of the 750 metres core-drilled analysed plus 100ppmAs. Sixty metres of core showed over 100ppb Au; the highest As over 20,000ppm and the highest Au over 1.2ppm. The distribution of values suggesting smaller-scale channeling within the larger fluid-permeable body. With nearly all the good values in 3 of 8 holes the drill-hole distribution leaves open the possibility of 50 to 150m x 1 to 20m shoots within the mineralised schist.
At Capburn only one of three targets developed by soil sampling was drilled. At Raggedy Range soil sampling is yet to be done to develop drill targets.
