"So a couple of outstanding items and we're hoping to make a decision on that in the near future. Service. Primary minerals are chalcopyrite, pyrrhotite and arsenopyrite. OAO RussNeft.

Maybe you're feeling lonely? Both are contained within the Lower Proterozoic Urquhart Shale. Australia is estimated to have about 13 per cent of the world’s economic resources of copper, the second largest behind Chile. apparently up to 1939, it was described that “ore as low as” 15.99% Cu had been shipped and not made money.The report went on to describe that hematite-specularite mass at Mount Oxide is not an uncommon amoung well-known copper districts in Arizona, New Mexico and Nevada. The treatment of copper ores was in full swing in the 1970s. Silver and zinc were removed from the surface oxidized zone and were deposited as supergene ore at a depth above the primary ore.Copper occurs in brecciated “silica-dolomite” rock. However, mining and closure of operations continued to fluctuate until recent times.Capricorn Copper recent acquisition of the Mammoth and Esperanza deposits (Figure 6) which is now renamed Capricorn appears to be creating some interest in the area.
In Figure 5 below, one can see a more schematic representation of the orebody.Figure 5: Schematic cross-section of the Mt Isa Mine showing the anomalous east-dipping to subhorizontal fault contact controlling mineralisation. These artworks have got you coveredVictoria records 76 new cases and 11 deaths overnightHumans might have lived at this coastal site 120,000 years ago — the trick lies in proving itFive things we heard in the committal hearing for the Yuendumu police shootingA party of one: Can Territory Alliance survive with Robyn Lambley as its sole survivor? Mining company Glencore says it is still considering the extension of its copper smelter operations in Mount Isa, in north-west Queensland, despite the company's plummeting share price. The Mt Isa and Cloncurry mineral field is heaven for base-metal style mineralisation or a more scientific nomenclature, the IOCG style of mineralisation.According to the Australian Department of Industry,  copper is one of Australia’s top ten commodity exports, worth about AUD$6 billion a year. Those that have read my writings over time would attest to my liking for the copper story. What COVID-19 scenarios might Melbourne be facing? If you believe that copper pricing will rise with time, then these deposits are going to become highly profitable. Distribution information Distribution information.

Owing to the remote location, little production took place until the 1920s.The main mining periods were 1927 to 1943 and 1955 to 1960, when the higher grade ore was worked by underground methods with access via an adit; and 1967 to 1971, when the lower-grade envelope and remnants of high-grade ore were bulk mined in an open-cut.Underground mining produced 79,000 tonnes of ore (15.9% Cu) for a yield of 12,500 tonnes of copper, and some 355,000 tonnes of ore averaging 2.5% Cu were treated at the Gunpowder concentration plant in 1970–71.
Nordenhamer Zinkhuette.

It is very rare to have one “mine” isolated within the emplacement of the deposit.Mount Oxide was discovered by Ernest Henry in 1882.

Deep hole navigational drilling Glencore Mount Isa Mines – George Fisher. Minor arsenopyrite, marcasite, chalcopyrite, valleriite, proustite, polybasite and argentite also occur. The abandoned townsite is about 1 km south of the existing open pit.Mount Oxide Mine is now classed as an abandoned mine site as there is no current mining lease or environmental authority in place.An 80% increase (announced on 28 February 2008) in the Mount Oxide mineral resource estimate to 203,000 tonnes of contained copper, together with the majority Indicated status of the resource, strengthens the project’s potential for development in the current strong copper market.Mount Oxide has considerable potential as a low cost near term development project. Away from all the traditional copper regions and armed with the discovery of a potential mine making mineralisation in Victoria,  We don’t hear of too many copper discoveries because it is expensive and like nickel sulphides, it is not simple exploration. The Urquhart is 1,000 metres thick and is a grey dolomitic shale with tuffaceous horizons. Isa region in Queensland. Mount Isa contains two separate orebodies: a stratigraphically lower lead-zinc-silver ore horizon and an upper copper ore. It is interesting to note that this is higher than the traditional copper countries such as Peru, Mexico, the USA, Indonesia and China. SEDEX: The Biggest Lead and Zinc Deposits in the World. I have touched on copper several times in the following articles,Mining in Queensland is known for lead, zinc and bauxite. (source: Geoscience Australia)Figure 3: Queensland’s new resources and mineral intersections map. Over the years, I learnt that this region is famous for great copper, zinc, lead and silver mines and later learnt the term IOCG (The region was made famous in 1923 by the discovery of a world-class copper lead zinc and silver deposit by John Campbell Miles. Their presence can be regarded as short-range guides to ore because copper ore-bodies commonly are associated with them and, if present, usually touche their peripheries at dome point. Note the discrete nature of the copper and lead-zinc ore. (source: Geomechanical Modelling of the Mount Isa Copper Deposit – Predicting Mineralisation – Scientific Figure on ResearchGate. These guys were pitching their technology story and had this slide up.
