ABOUT MINCO

Minco Plc, registered in the Republic of Ireland and listed on the AIM Alternative Investment Market of the London Stock Exchange ("MIO"), is an exploration and development company, currently engaged in zinc-lead exploration in the United Kingdom, Ireland and Canada and with investments in zinc‐silver projects in Mexico through holding 30 million shares (~29%) in Xtierra Inc. listed on the TSX Venture Exchange (TSXV-"XAG"). Minco holds 15.4 million shares (~10%) in Buchans Minerals Corporation also listed on the TSXV ("BMC"). Minco also holds a 2% NSR royalty on the Curraghinalt gold property in Northern Ireland which is being explored by Dalradian Resources Inc. (TSX-"DNA").

On 2 November, 2012, Minco announced that it had commenced a new exploration initiative in the North Pennine Orefield located in the English counties of Cumbria, Northumberland and Durham. Minco plans an initial US$ 1 million exploration program, including 4,000 metres of diamond drilling which is now underway.

The Pennines area was extensively mined in the past, with the main mining effort starting in the mid-seventeenth century and, in terms of zinc-lead production, continuing without interruption until the end of the nineteenth century, and at a reduced scale up until 1938. For most of this period, lead was the only metal of economic interest and the English Pennines was recognised as one of the primary lead producing areas in the world.

Minco believes that there is significant untested potential for zinc lead mineralisation at the base of the Carboniferous succession, approximately 300-400m below previous, adit-accessed workings, and such new deposits could be significantly larger than any previously discovered.

These deeper horizons have never been explored, although they are known to be mineralised where they outcrop at the edge of the orefield. Minco believes that the lower formations could prove to be the principal mineralised horizons, hosting stronger and more extensive zinc-lead mineralisation than any worked previously in the overlying Great Limestone approximately 400m above.
