在澳大利亚新南威尔士州北部阿米代尔以东30公里的Hillgrove矿区,新英格兰锑公司(NEAM)经营着一个小型锑金矿和一个选矿厂.该公司租借了大部份大型废旧巷道,但自1971年起,采矿活动已主要集中于Smith‘s、Freehold、Eleanora和Gari-baldi矿脉走向线上.辉锑矿(Sb_2S_3)成矿在低温热液矿脉中:脉石为石英及少量方解石.伴生矿物有黄铁-磁黄铁矿、砷黄铁矿、白钨矿、绿泥石和金.矿化带宽度平均300～400毫米.
At Hillgrove, 30 km east of Armidale, northern New South Wales, Australia, New Antimony Gold Company (NEAM) operates a small antimony gold and a concentrator, which renters most of the large abandoned roadways but from Since 1971, the mining activities have been mainly focused on the Smith’s, Freehold, Eleanora and Gari-baldi ore-line trends.Smigrant Sb2S_3 mineralization in the low-temperature hydrothermal veins: the gangue is quartz and a small amount of calcite. Minerals are pyrites - pyrrhotite, arsenopyrite, scheelite, chlorite and gold. The average width of the mineralized zone is 300-400 mm.
