Update on Mambare and Direct Nickel Pty Ltd;

Red Rock Resources Investment in Ascot Mining.

19 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 announces that it has reached agreement to invest in Direct Nickel Pty Ltd ("DNi"), and for joint financing with DNi of an exploration programme at the joint venture Mambare lateritic nickel/cobalt project in Papua New Guinea. It also reports on an investment by its 20.96% associated company Red Rock Resources plc (AIM:RRR).

Background

On 6 November 2009 the Company announced a joint venture with DNi, under which the parties agreed to co-operate on a 50/50 basis in the piloting and application of DNi's advanced nickel/cobalt leaching technology at Regency's Mambare lateritic nickel project in Oro Province, Papua New Guinea. Changing market conditions and nickel price developments coupled with new geophysics flown over the Mambare area for the Papua New Guinea government in Spring 2010 have resulted in a revised exploration and drill programme and a proposal for an initial £1.5m drill programme has now been prepared.

Subscription to DNi

Regency has agreed to subscribe for a new issue of shares by DNi on the same terms of investment as those of DNi's last funding round and value DNi on a pre-funding basis at US$75,000,000. Regency's investment will be for a total amount of $6,000,000 in two equal tranches of $3,000,000, the first for payment within seven days of 18 November 2010 and the second for payment one month after that date. The consideration will be settled by the issue of new shares in the Company, at a price equivalent to the volume weighted average share price of Regency in the five trading days up to and the five trading days after 18 November 2010.

Exploration Joint Venture

Regency and DNi have agreed that they will each contribute £1,000,000 to the next phase of exploration at Mambare, which will start immediately. It is provided inter alia that an Operating Committee will be set up to conduct this programme which will consist of two representatives from each of DNi and Regency. The Exploration Manager, who will be nominated by DNi and approved by the Company, will be a member of the Operating Committee. The committed budget will be drawn down in tranches from DNi and Regency by the Operating Committee as work proceeds.

Other Matters

The existing agreements and understandings between the parties in relation to the joint venture are not superseded but continue to guide the parties in their conduct, and over the next weeks the parties will consider, revise, and adapt the detailed documentation laying out the next stages.

A further and fuller announcement is expected to be made next week.
