These explosive hydrothermal processes fractured and brecciated the host rock, creating open cavities and fracture zones that were later filled by silica-rich fluids, allowing quartz crystals to grow throughout the specimen.\u003c\/p\u003e\n\u003cp data-start=\"205\" data-end=\"629\"\u003e \u003c\/p\u003e\n\u003cp data-start=\"631\" data-end=\"1034\"\u003eThe specimen contains sulfide-rich refractory gold mineralisation with minute silver values and antimony-bearing minerals. Some free gold is present within the ore, however it occurs in micron-sized particles typically only visible under magnification or a microscope. Most of the gold remains locked within sulfide minerals, making the ore refractory and unsuitable for simple gravity recovery methods.\u003c\/p\u003e\n\u003cp data-start=\"631\" data-end=\"1034\"\u003e \u003c\/p\u003e\n\u003cp data-start=\"1036\" data-end=\"1065\"\u003eThis specimen is ideal for:\u003c\/p\u003e\n\u003cul data-start=\"1066\" data-end=\"1300\"\u003e\n\u003cli data-section-id=\"p8abp0\" data-start=\"1066\" data-end=\"1101\"\u003eMineral and crystal collections\u003c\/li\u003e\n\u003cli data-section-id=\"omj6l5\" data-start=\"1102\" data-end=\"1136\"\u003eGeological display collections\u003c\/li\u003e\n\u003cli data-section-id=\"1ek2f2p\" data-start=\"1137\" data-end=\"1171\"\u003eRefractory gold ore collectors\u003c\/li\u003e\n\u003cli data-section-id=\"10v9ime\" data-start=\"1172\" data-end=\"1206\"\u003eEducational and study purposes\u003c\/li\u003e\n\u003cli data-section-id=\"bqkg90\" data-start=\"1207\" data-end=\"1254\"\u003eQuartz and hydrothermal mineral enthusiasts\u003c\/li\u003e\n\u003cli data-section-id=\"14kxwmt\" data-start=\"1255\" data-end=\"1300\"\u003eSulfide ore and mineral specimen collectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp data-start=\"1302\" data-end=\"1340\"\u003e\u003cstrong data-start=\"1302\" data-end=\"1320\"\u003eSpecimen Size:\u003c\/strong\u003e\u003cbr data-start=\"1320\" data-end=\"1323\"\u003e9cm x 9.5cm x 6cm\u003c\/p\u003e\n\u003cp data-start=\"1302\" data-end=\"1340\"\u003e \u003c\/p\u003e\n\u003cp data-start=\"1342\" data-end=\"1369\"\u003e\u003cstrong data-start=\"1342\" data-end=\"1367\"\u003eImportant Disclaimer:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1371\" data-end=\"1534\"\u003eThis specimen is sold strictly as a collectible geological display sample.
