World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil. Production in Australia was 530 Mtonne. South Australian total production in 2013 was in the order of 12 Mtonne, including 3.2 Mtonne of magnetite direct shipping ore, and 665,000 tonne of magnetite concentrate. 

Ore production in Australia is overwhelmingly from high-grade hematite and pisolitic goethite-limonite deposits, mostly in the Hamersley Basin region of Western Australia. A recent trend has been production of a high-grade magnetite concentrate from beneficiation of low-grade magnetite ore. Resources of this latter material are enormous, in particular in Western Australia, and South Australia, with significant resources also in the Northern Territory, and Queensland. 

The history of iron ore prices differs significantly from other metals. For most of its history the price of iron ore has been fixed globally, and for very long periods. Since the beginning of global pricing, which is pre-1900, the price has remained relatively fixed up until 2003. In that ~100 year period the price changed only once, from A$2/tonne to A$9/tonne in 1965. Since 2003 the iron ore price has fluctuated, reaching a peak of ~A$120/t in 2011. Since then the price has fallen in an erratic but steady decline some 40% to a September 2014 price of A$85-90/t

The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'high-grade' ore, and banded metasedimentary ironstone, magnetite-rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'low-grade' ore

Currently most of the iron ore mined in the world comes from large deposits of massive hematite rock formed by the in situ enrichment of a protore already enriched in iron, most commonly a banded iron formation (BIF)

Norden Crown Metals Corp. is pleased to announce an exceptional discovery at its 100% owned Fredriksson Gruva prospect (“Fredriksson Gruva”) demonstrated by significant results from the first three holes drilled below historical mine workings

Norden Crown Metals Corp. (TSXV: NOCR) is pleased to announce an exceptional discovery at its 100% owned Fredriksson Gruva prospect (“Fredriksson Gruva”) demonstrated by significant results from the first three holes drilled below historical mine workings.  The discovery holes intersected significant mineralized widths ranging from 8.15 to 13.60 metres of precious and base metal, massive and semi-massive sulphide mineralization, within a geological setting unique to mineralization belonging to the Broken Hill Type (“BHT“) clan of silver rich zinc-lead ore deposits

“We are delighted to present to our shareholders robust silver-zinc-lead intersections which are part of a bonafide Broken Hill Type mineralizing system at Fredriksson Gruva; the widths and grades intersected beneath the historical mine workings suggest that the Gumsberg Project has exceptional growth potential”. Stated Patricio Varas, Chairman and CEO of Norden Crown. “Massive sulphide deposits are special because it is possible to delineate large tonnages from comparatively small drill footprints due to the high density of the mineralization. To put these results into perspective, Norden Crown’s GUM-20-09 intercept is comparable in width to the height of a three storey building.”

*Insufficient drilling has been completed to definitively determine true thickness; true thickness is estimated to be between 90-95% for holes GUM-20-09 to -11 based on angle to core axis and 3D interpretation. Metal ratios are calculated assuming 100% recoveries at US $1806 Gold, US $27.65 Silver, US $ 1.05 Lead and US $ 1.29 Zinc

The three discovery drill holes (totaling 569 metres) completed at Fredriksson Gruva were part of an eleven hole 2,365.6 metre diamond drill program completed at the Company’s 100% owned Gumsberg Project, located in the Bergslagen Mining Region of southern Sweden. The objective of the drill program was to demonstrate that mineralization continues beneath the historical mine workings, which extend to 91 metres below surface. The program was also designed to confirm historical silver-zinc-lead grades, thicknesses, and to test the continuity of this mineralization. Holes GUM-20-09 and GUM-20-10 are positioned 30 metres down plunge of the historical underground workings and are spaced 40 metres apart. Hole GUM-20-11 is 30 metres below GUM-20-10 (60 metres below the historical workings) (see Figure 1)

Iron has a chemical formula (Fe), and it is one of the most common elements in the world and forms 5% of the crust of the Earth. It ranks the fourth among the common elements after Oxygen, Silicon, and Aluminum. Iron forms a critical part of modern civilization and its use dates back to thousands of years. It was only around the 14th Century when its use became widespread as smelting furnaces increasingly began to replace the older forges. Iron ore occurs in the form of rock from which the metallic iron is the final product. The bulk of these rocks are either Hematite or Magnetite, and it makes almost 98% of the iron ore produced worldwide that goes into making steel. Much of the iron ore mined are oxide compounds of Magnetite (Fe3O4), Hematite (Fe2O3) Goethite (Fe2O3SH2O), and Limonite. Magnetite is composed of 72% iron, Hematite is 70% iron, Goethite is 63% iron, and Limonite is 60% iron.

Much of the iron ore are in the sedimentary rocks called Banded Iron Formations (BIFs), which dates back to more than 542 million years. They are present in all continents and mined as iron ore or rocks containing iron ore. Deposits that contain at least 60% Fe are often commercially viable for mining, but in some case deposits of 56% Fe have been commercially mined successfully in different countries.

China is by far the largest producer, consumer, and importer of Iron ore. In 2015 it produced 1.3 billion tons of iron ore equivalents to 44% of the world’s output. In 2014, China produced 1.5 billion tons of crude ore extracted mainly in Hebei and Liaoning provinces of mainland China. Other regions include Shanxi, Beijing, and parts of Inner Mongolia.

Australia comes as the second largest producer of Iron ore and has the world’s biggest deposits. The mineral is mainly in the Western Australia in the regions of Pilbara, which represents 95% of Australia’s iron ore. The region forms three of the eleven biggest mining operations in the world. In 2015, Australia produced 824 million tons of iron ore and in 2014 was 774 million tons which represent more than 20% of the global output.

Brazil is the third largest producer of iron ore producing 428 million tons in 2015 and 411 million tons in 2014. The 2015 output represents 12% of the world’s production. Brazil has the second largest deposits of iron ore in the world. The mineral is mined mainly in Minas Gerais and Para states. Carajas is the world’s biggest iron ore mine owned by Vale the Brazil’s industry giant.

In the past, India has been a world leader, but now the fourth largest producer. 95% of the country's iron ore come from Orissa, Chhattisgarh, Jharkhand, Madhya Pradesh, Goa, and Karnataka. The biggest deposits in the country are in Orissa state. In 2015, India produced 129 million tons which were similar to 2014 figures.
