Regency Mines PLC (AIM: RGM; Frankfurt: RM4) is quoted on the Alternative Investment Market of the London Stock Exchange Ltd in London and on the Frankfurt Exchange. The company is focused on exploring areas of copper and nickel potential in Western Australia, Queensland, and Papua New Guinea.

It seeks to add shareholder value by systematic exporlation and, where appropriate, development of these assets, and by joint venture, acquisition, and disposal.

Since 2006 the company has operated the Mambare Plateau lateritic nickel project in Papua New Guinea, now 100% owned. The Mambare Plateau, the central part of which is 20km by 7km, is extensively mineralised. In 2008, the company completed sampling results which have confirmed the presence of a substantial nickel-cobalt deposit. On the 19th of August 2009, Regency announced its intention to form a joint venture with Direct Nickel Proprietary Limited, which has developed atmospheric tank leaching technology with potential to reduce the capital and operating costs of nickel and cobalt extraction from laterites. The two companies intend to create a new company which will raise money for further exploration and a pilot plant.

Regency retains and has recently added to, substantial ground holdings in the Lake Johnston greenstone belt in Western Australia. Regency's interests now extend over more than half the known strike length of the belt, which has been relatively under-explored. Recent gravity and magnetic work and reinterpretation of old data have identified nuberous drill targets.

The company owns just under 30% of Red Rock Resources Plc and 15% of Alba Mineral Resources Plc.
