India. 



The following particulars with regard to India are taken from a 

 note kindly prepared for me by Dr. Coggin Brown, of the Indian 

 Geological Survey. 



Important deposits of high-grade iron-ore, mainly ha?matite, 

 associated with banded jasper, and in this respect similar to those 

 of Lake Superior and Brazil, have recently been opened up in India. 

 The best-known deposits are those of Mayurbhanj and Singhbhum, 

 in Bihar and Orissa ; Chanda and Drug in the Central Provinces ; 

 Kadur in Mysore; and Goa. The Mayurbhanj deposits are being 

 worked by the Tata Iron and Steel Company at Gurumaishini, 

 where a lens of haematite has been proved to contain 15 million tons 

 for every 10 feet of depth. This ore averages over 60 per cent iron, 

 manganese 0'8, sulphur O'Ol, and phosphorus 0"09. The basic 

 pig made from this ore at the Tata Ironworks, which are situated 

 within 40 miles of the mine workings, contains about 0'04 per cent 

 phosphorus, under 0"05 sulphur, and less than 1 per cent silicon. 

 Similar ore bodies are known at Okampad and Badampahar. 



The Singhbhum deposit is being worked at Pansira Hill and Budu 

 Hill, south-east of Manharpur, on the Bengal-Nagpur Railway. It 

 appears to be a part of an iron-ore range forming a definite horizon 

 in the Dharwar rocks, and extending for some 40 miles in a south- 

 westerly direction from Singhbhum. Enormous quantities of ore 

 are believed to exist, but until the supposed extensions have been 

 definitely proved in depth by drilling, no estimate as to quantity 

 can be made. 



In the Chanda and Drug districts of the Central Provinces, 

 deposits of high-grade low-phosphorus ore have been discovered, 

 but have as yet not been extensively prospected. The Mysore ores 

 are not of great extent. They are being worked tentatively by the 

 Tata Iron and Steel Company, for the Mysore Government. High- 

 grade low-phosphorus ores exist in Goa and Ratnagiri, probably 

 in considerable quantity ; but they have not as yet been proved in 

 depth. 



Altogether the reserves of high-grade ore already partly proved in 

 India may be safely put at several hundred million tons, and the 

 prospects are favourable for the existence of very much larger 

 quantities. 



Australia. 



Little is known of the iron-ore resources of Australia except 

 that many important deposits exist both near the coast and in 

 the interior. Some of these are at present being investigated in 

 South Austraha, Western Australia, Queensland, and Victoria. 



A high-grade ore is being worked in South Australia by the 

 Broken Hill Proprietary Company at Iron Knob. The ore is carried
