>>>>>>>>>>> oh limp ick damn? >>>>>>>>>>> says here ....... 3) Vein and disseminated uranium (in addition to Cu ± Au ± Co) mineralisation occurs in and proximal to hematite and/or magnetite breccia zones hosted by sedimentary, intrusive and/or volcanic rocks adjacent to regional-scale fault systems in extensional environments. Associated elements include any or all of Cu, Co, Au, Ag, La, Ce, F and Ba. Gangue minerals include carbonate, quartz, feldspar, sericite, fluorite and barite. Alteration includes hematisation, sericitisation, extensive sodic (albite, scapolite) and/or potassic (K-spar, biotite) alteration and/or abundant carbonate. Example: Olympic Dam (2320 Mt, avg. 0.4 kg/t U O , 1.3% Cu, 0.5 g/t Au, 2.9 g/t Ag). Favourable target areas in the Yukon for this 3 8 style of mineralisation are those underlain by Paleoproterozoic Wernecke Supergroup and ?Paleo- to Mesoproterozoic Wernecke Breccia, e.g. Wernecke and Ogilvie Mountains. geology.gov.yk.ca btw - thanks -learned something today .... you can hump this stuff 3 ways: Unconformity-associated model: Vein-type model: IOCG model: and I think CHX represents the IOCG model but have to confirm? that somehow. in any event, thanks, regards, John
