Canada's junior explorer Hana Mining CEO Mareck Kreczmer believes his company has on its hands part of one of the largest copper and silver deposits in Africa that can rival the Zambian copper belt.

The official figures now have growth at 7.4 per cent and some, such as Marc Faber of the Gloom, Boom and Doom Report, suspect it may be more like 4 per cent. More telling are some of the non-official numbers. Komatsu’s sales of excavators to China fell 43 per cent year on year in August (marking the 16th consecutive monthly decline). If sales of excavators are falling you can assume that activity in areas in which excavators operate is also falling. Goodbye supercycle.

Speculation has centred on two Chinese firms – Chinalco Mining Corp, a subsidiary of China's state-run aluminum group, and Hong Kong-listed MMG – who may be weighing rival bids for the three Las Bambas open pits which will also produce significant quantities of gold, silver and molybdenum as by-product.

Copper ranks second to silver as an electrical conductor. The copper cladding of LEONI Histral® H16 ensures a good electrical conductivity whenever mechanical properties do not play a primary role.

High-frequency (HF) technology In HF technology the so-called „skin effect“ ensures that the current flow is restricted to a very thin layer situated on the surface of the conductor and that the overall resistance in the conductor is reduced. LEONI Histral® H16 has copper, which features good electrical, in the cladding only. The additional galvanic plating of the surface causes the skin effect to be optimized. Aeronautics and automotive technology Weight is of major importance for the construction of airplanes and automobiles. LEONI Histral® H16 is particularly suited for larger cross-sections here that can be employed for the transmission of power, where there is a significant weight reduction potential. Shielding braids LEONI Histral® H16 features a resistivity lending itself well to shielding braids because high coverage can be achieved at a comparatively low weight. The fact that aluminum suffers from the drawback of having a poor contact resistance is largely offset by the copper cladding. Heating applications The combination of a relatively good resistance value with a rather low mechanical resilience suggest that LEONI Histral® H16 may well be used in all kinds of heating applications that are not exposed to a permanently varying level of stress.

At stake is a copper-molybdenum-silver mine which when built will be the third largest copper operation in the US and supply 10% of the country's red metal.

Nautilus Minerals has developed robotic technology for deep-sea mining in collaboration with the French company Technip. The company is planning to open the first deep-water mine in 2015. The Solwara 1 mine will be located 1600 metres below sea level. The company has found large deposits of copper and gold there. Solwara 1 is located in the Pacific Ocean, north of Australia, in Papua New Guinea.

The mine would be Botswana’s largest copper operation producing some 34 400t of copper and one million ounces of silver annually.

TORONTO (miningweekly.com) – A precious-metals streaming deal with Silver Wheaton will cover about a quarter of the cost to build Augusta Resource's Rosemont copper project, in Arizona, and the company expects to have the balance of the capital tied up by around the end of the third quarter, CEO Gil Clausen said on Thursday.
