Update on Mambare and Direct Nickel Pty Ltd

30 November 2010

Regency Mines, the mining exploration and mineral investment company with interests in nickel and other minerals in Western Australia, Queensland, Papua New Guinea and Pakistan, announced on 19 November 2010 that it had entered into an agreement whereby the Company was to invest in Direct Nickel Pty Ltd ("DNi"), and the two parties would, pursuant to their joint venture, jointly finance the next stage of exploration at Regency's Mambare lateritic nickel/cobalt project in Papua new Guinea.

Direct Nickel Pty Ltd and the Direct Nickel Process

DNi is a private company incorporated in Australia. It is currently demonstrating a potentially revolutionary process with attractive economics for treating laterite nickel ores (the "Direct Nickel Process" or the "Process").

The Direct Nickel Process is a hydrometallurgical process for treating nickel laterites with unprecedented efficiency and environmental benefits. It is designed to operate with tank leaching at atmospheric pressure, and is the first to treat both limonite and saprolite ores with a single flowsheet. The Process recycles its novel reagents, offers high cobalt and nickel recoveries with short residence time, produces mixed hydroxide precipitates ("MHP") or sulphide concentrate, has substantially lower capital and operating costs than competing processes and is fully scalable.

DNi owns the worldwide perpetual rights to the Process which it developed from precursor processes originally developed in the chemical processing sector in the USA. DNi has spent more than USD 14m over the past three years on proving the Process, partly through technical partnership with its shareholder and major Canadian miner Teck Resources Limited.

The Direct Nickel Process has the potential to revolutionise the economics of global nickel production.

Direct Nickel Pty Ltd and Regency Mines plc

DNi and Regency first announced a joint venture co-operation on 6 November 2009 with a commitment to pilot and apply DNi's advanced nickel-cobalt extraction technology.

Regency Mines has now subscribed AUD 3,000,000 (approximately £1,852,520) for a first tranche of 519,930 new shares in DNi at AUD 5.77 per share ("First Tranche") and will subscribe AUD 3,000,000 for a further tranche of 519,930 new DNi shares on 19 December 2010. The First Tranche is being settled by the issue of 26,841,114 new Regency shares at a price of 6.9018 pence per share. DNi currently has 13,192,029 shares in issue and, on completion of the second tranche, Regency will have a shareholding equivalent to approximately 7.31% of DNi's enlarged issued share capital. The subscriptions attribute a valuation to DNi of approximately USD 75,000,000, the same basis as an investment by the Commonwealth Scientific and Industrial Research Organisation ("CSIRO"), Australia's national science agency, in June 2010.

Next steps

The Direct Nickel Process reagent recycling circuit demonstration was completed in August 2010 at its facility in Charlotte, North Carolina, and DNi is now in the final design phase for the building of a Demonstration Plant at Waterford, Perth.

A joint technical team of DNi and the CSIRO will build a Direct Nickel Process prototype facility to process one to five tonnes a day of ore from various deposits in which DNi has equity participation.

Regency and DNi have agreed that they will each contribute up to £1,000,000 to the next phases of exploration at Mambare which is planned to commence in January 2011 with the twin objectives of drilling out a resource and testing further areas of mineralisation.

Other

In its unaudited results for the year to 30 June 2010, DNi made Pre-Tax Losses of AUD 4,795,221 and had Net Assets of AUD 1,067,204 at that date.

As shareholder in Direct Nickel, Regency joins Canadian miner Teck Resources Limited, Australian copper-gold company OZ Minerals, and the CSIRO.

Regency considers this investment an important step, both in furthering its strategic alliance and co-operation with DNi, and in allowing it to become a significant shareholder at an early stage in a mining technology that may change the nickel processing industry.

Application will be made for the 26,841,114 new Regency shares, which rank pari passu with the Company's existing issued ordinary shares, to be admitted to trading on AIM. It is expected that admission will become effective and that trading will commence on 3 December 2010. Following the issue of the new Ordinary Shares the Company's enlarged issued ordinary share capital will be 534,192,891 Ordinary Shares.
