(MENAFN- ProactiveInvestors)Commodity prices may have tumbled but Cambridge Mineral Resources (CMR) sees the fall as a help rather than a hindrance. CMR which went private in 2009 hopes to relist on the AIM market in February or March next year to help it develop its copper-zinc assets in Spain. It says copper and zinc prices may have bottomed out and that presents a market opportunity. Mark Slater chief executive said: 'The commodities market is a bit depressed at the moment but there are one or two opportunities. 'When you get into a market it's always best to do it at the bottom because there's only one way it can go. 'Now's a very good time if you're correctly funded to exploit some of those opportunities.' Joint venture CMR was founded in 1992 and initially had concessions in South America Europe and Romania. But it has since refocused and now concentrates on the Iberian Pyrite Belt in southern Spain where it is investigating the Masa Valverde copper-zinc deposit near Huelva. It is also evaluating a number of other mining projects in the Andalucia region. The group is developing Masa Valverde in a joint venture with commodity giant Glencore (LON:GLEN) which has just taken a 60% stake in the firm's Spanish subsidiary. The companies are close to completing 28000 metres of drilling on a concession at the deposit and are about a year ahead of schedule. Glencore has been cutting copper and zinc output and selling copper mines as it moves to reduce debt. But other miners have said copper demand fundamentals remain good supported by power infrastructure development in China. Slater said Glencore was already building mining infrastructure at Masa Valverde and had clear plans stretching into 2017 to take the project forward. It has all the rights to the eventual output from the project which is not expected to enter production until 2021. 'We have no concerns regarding Glencore's continued involvement at this time' Slater said. Bumpy recovery Last month the price of copper dropped close to its lowest level in six and a half years. Demand for the metal used by industries ranging from telecoms to car-making has taken a hit from the Chinese economic downturn. Goldman Sachs has predicted that copper prices would fall to US$4800 a tonne by the end of 2015 and to US$4500 by the end of next year. Capital Economics said it expected the recovery in prices of copper and other commodities to be bumpy. But it said sentiment towards commodities had become too pessimistic and may be bottoming out. The economic research group cited growing evidence that previous sharp price falls were prompting the supply cuts necessary for a sustained recovery. Capital Economics head of commodity research Julian Jessop said: 'Glencore has dominated the headlines recently but is not alone in the mining sector while there have also been substantial cuts in oil industry investment." Capital Economics said it expected copper prices to rise to US$7000 per tonne by the end of next year against about US$5280 now. CMR's Slater said he did not think copper and zinc prices were going to drop much further. China had not stopped buying copper and zinc despite reducing the quantities it was purchasing. 'I think prices are pretty much at the bottom' he said. 'I think copper prices are stable and will slowly edge up.' CMR is expected to have a market capitalisation of about £10m when floated and expects to raise only a relatively small proportion of that figure in the listing. Management owns about half of the company and about 2500 private investors including a couple of institutions own the rest. Slater says the flotation should enhance the profile of the company among investors and awareness of its assets. 'The assets are so prospective that they deserve the opportunity to advance in the open market' he said. CMR has appointed Grant Thornton UK as its nominated adviser and Northland Capital Partners as brokers.
