Notice of AGM and Annual Reports & Accounts

Dublin, 30 June, 2010 - Minco Plc (AIM-"MIO"), the Irish exploration and development company, (the "Company") is pleased to announce that its Annual General Meeting (AGM) will be held at D4 Berkeley Court Hotel Pembroke Rd, Ballsbridge, Dublin 4, Ireland on 28 September, 2010 at 11.00 a.m.

The Report and Accounts for the Company for the year ended 31 December 2009 have been published today and are being posted to shareholders, together with the Notice of AGM and Form of Proxy. Copies of these documents will be available on the Company's website www.minco.ie and will also be available on request for one month from 3July 2010, free of charge, from the Company's registered office at Connaught House, Burlington Road, Dublin 4, Ireland.

In a letter to Shareholders, Executive Chairman John F. Kearney said, "Minco Plc moved closer to its goal of developing a new zinc-lead mine at Pallas Green, near Limerick, Ireland. Minco holds a 23.6% interest in the Pallas Green Joint Venture with JV partner Xstrata, the world's largest zinc producing company.

During 2009, twenty-three diamond drillholes were completed for a total of 10,321 metres. Exploration primarily concentrated in the western part of the Pallas Green block in the region around the Tobermalug deposit with the twin objectives of extending the size and grade of the Tobermalug deposit, through a combination of step-out holes and by closer spaced, in-fill drilling within the confines of the known Tobermalug resource to provide better definition and continuity of mineralization.

During 2009, a preliminary Scoping Study was undertaken to provide a number of reports including a resource estimate prepared to JORC standards, a preliminary mining plan, a preliminary metallurgical report, preliminary cost estimates as well as preliminary environmental base line studies.

In August 2009, Xstrata Zinc published an initial JORC compliant resource estimate for the Tobermalug deposit of 11,300,000 tonnes grading 10.2% zinc and 1.9% lead in the "Inferred" resource category which is estimated to contain 1.15 million tonnes of contained zinc metal and 215,300 tonnes of lead metal (worth over US$3 billion in situ). This resource calculation was made as of June 2009 at a 6% cut‐off using the inverse distance weighting method (IDW). The resource was calculated in accordance with the JORC Code for Reporting of Mineral Resources and Ore Reserves of the Australasian Joint Ore Reserves Committee.

Drilling in 2009 and into the first half of 2010 continued to focus on Tobermalug where a preliminary mineral inventory, estimated by Minco at about 17 million tonnes (of about 10.2% zinc plus lead combined), has now been outlined in what is believed to be a semi-continuous zone which remains open to the south, to the northwest and west. This represents an increase of about 20% from Minco's estimate of 14 million tonnes made at this time last year. This mineral inventory estimate is not, and should not be interpreted as a JORC compliant resource estimate.

Minco remains convinced that the Pallas Green project is the premier zinc exploration project in Ireland. The prospective area is approximately 25 km long and 4-5 km wide but, importantly, 60% of the property remains relatively unexplored. Seven distinct lenses of massive sulphide zinc lead mineralization have now been discovered and Pallas Green is without doubt the largest mineralized area ever discovered in Ireland. Importantly, the mineralized areas remain open in most directions.

To the end of 2009, a total of €11.5 million had been expended on the Pallas Green project since 1998, resulting in a discovery cost of less than €1.00 per tonne of JORC compliant zinc resources, a cost considered to be very low by industry standards."

Xtierra - Developing Mexican Precious and Base Metal Production

Following the successful floating of its Mexican properties on the TSX Venture Exchange (Toronto) in 2008, Minco holds 30 million shares of Xtierra Inc. (TSXV | XAG). Xtierra has interests in base and precious metal mineral deposits on properties located in the Central Mexican Silver Belt, in and around the States of Zacatecas and San Luis Potosí, Mexico. This area is an important source of Mexico's silver production from the early colonial period to the present day and hosts many world-class silver and base metal deposits.

During 2009, Xtierra initiated a two-phase feasibility study on its Bilbao silver-zinc-lead-copper deposit in Zacatecas. In February 2010, Xtierra released a new independent resource estimate, compliant with National Instrument 43‐101, for Bilbao showing a 169% increase from the November 2008 estimate in the Indicated resources to 9.68 million tonnes and an increase of 68% in the Inferred resources to 4.04 million tonnes.

Xtierra is currently well financed to complete the feasibility study on the Bilbao project and expects to make a production decision by the end of Q3 2010.

Focus on Pallas Green in 2010

As we move forward in 2010, the international minerals sector appears to have rebounded from the late 2008 downturn largely fuelled by demand from the massive infrastructure stimulus spending but the future, particularly for the base metals, rests heavily on sustained growth in the emerging economies of China, India and Brazil.

Minco completed a placement of £1.06 million in January 2010 and a further £1.04 million in April 2010, in difficult market conditions for junior equities, to ensure sufficient funds were available to participate fully in the Pallas Green Joint Venture.

Minco will continue to focus on the development of Pallas Green, which is the best exploration project we have seen in more than 40 years in this business. While there are no guarantees in exploration we believe it is imperative that Minco keeps up with Xstrata and maintains its share in the Pallas Green joint venture.

Pallas Green is a very exciting advanced zinc-lead exploration project and we remain very optimistic that this project will lead to the development of the next Irish zinc-lead mine, and the first new mine in Ireland since the early 1990s.

In 2010, the budget has been increased to €7 million and approximately 150 holes or about 70,000 m of drilling are budgeted."
