ZincOx was formed in 1997 by Andrew Woollett and Noel Masson. Noel Masson was formerly chief executive of Union Minière (now called Umicore), Europe's largest producer of zinc. It was set up to identify and develop zinc oxide deposits. [The term "oxide" is used here collectively to include all "non-sulphide" bearing minerals, e.g., carbonates and silicates etc]. In 1999, following the successful takeover of Reunion Mining PLC by Anglo American, Andrew Woollett and other key members of Reunion's management team joined ZincOx full time. This team, including Noel Masson, had been responsible for completing a feasibility study on the Skorpion zinc oxide deposit in Namibia. The study demonstrated that the deposit, which had hitherto been undeveloped because of its complex metallurgy, had the potential to become one of the lowest cost producers of zinc in the world, using the process flow sheet and technology developed by Noel Masson. Anglo American has now developed the deposit at a production rate of 150,000 tonnes per annum of zinc metal, at a cost of US$450 million, with an operating cost of US$660 per tonne of zinc. ZincOx's strategy is to reassess known zinc oxide deposits located throughout the world, rather than carry out relatively high-risk early stage exploration. Over its first five years the company investigated all the major zinc oxide deposits, work has been carried out on all the major zinc oxide deposits. As a result of this work, ZincOx acquired an interest in the Jabali zinc oxide deposit in Yemen and the Shaimerden zinc oxide deposit in Kazakhstan. ZincOx completed a feasibility study into the development of the Jabali deposit in March 2005 and in October of that year a Mining Contract was signed with the Government of Yemen. This contract was ratified by the Yemen Parliament and the President of Yemen in August 2007, and was the first such contract to be ratified in Yemen, representing a major success. Subject to the successful raising of project finance, construction of the project is planned to commence in early 2008. After successfully completing work on the deposit, the company's interest in Shaimerden was sold at a substantial profit at the end of 2003 for US$7.5 million in cash and a deferred payment related to the price of zinc, payable between 2007 and 2011. These payments are providing the company with a substantial early cash flow, commencing from January 2007. The successful metallurgical research carried out by the management of ZincOx into the treatment of primary zinc oxide deposits, has enabled the Company to develop a strategy for the recovery of zinc from secondary and waste materials (See Projects: EAFD). These include zinc contained in the waste derived from the recycling of steel, such as electric arc furnace dust (EAFD). In May 2006, the Big River smelter in Illinois was purchased, with the intention to convert part of the capacity to treatment of EAFD by installing a new leach and purification circuit but using the existing electrowinning and melting and casting facilities.
HudBay Minerals Inc. (HudBay) is an integrated mining company that operates mines, concentrators and a metal production complex in northern Manitoba and Saskatchewan. The Company also owns a zinc oxide production facility in Ontario, the White Pine Copper Refinery in Michigan, and the Balmat zinc mine in New York. Along with its two primary products, zinc and copper, the Company also produces gold, silver and zinc oxide. HudBay’s operations include three mines in northern Manitoba operated by its wholly owned subsidiary, Hudson Bay Mining and Smelting Co., Limited, and a fourth in the Balmat district of New York state. The Company’s principal processing facilities are located near its Manitoba mines and include two concentrators, a copper smelter and a zinc plant. The metals and zinc oxide HudBay produces are marketed and sold to customers by Considar Metal Marketing Inc., its agent, which is located in Toronto and is 50% owned by the Company. (Source: ARS)
