MINCO RECOMMENCES DRILLING OPERATIONS AT NORTH PENNINES EXPLORATION PROJECT

Dublin, 21 June 2013 - Minco Plc (AIM - "MIO") (the "Company") is pleased to report that diamond drilling at the North Pennines in the UK will recommence on Monday, June 24th.

It had not been anticipated or agreed that exploration activity would continue during the summer months due to environmental factors. However, in cooperation with regulatory authorities and local landowners, Minco has now agreed upon methods of operation and suitable locations to ensure that exploration can continue during this sensitive season.

The new exploration drilling will focus on extending Minco's understanding of the pervasive Zinc and Lead mineralisation discovered in all of the first phase drill holes. The programme will recommence with the drilling of three new exploration holes located in Cumbria County for a total of 750 metres of drilling. Additional holes will be proposed based on the results of the initial three exploration holes.

A total of 2,221 metres of drilling were completed during Minco's first phase of drilling in four (4) exploration drill holes completed by Irish Drilling Limited under contract with Minco Mining Limited, a wholly owned UK subsidiary of Minco plc.

Widespread, generally low grade, zinc-lead-pyrite mineralization was consistently encountered in all four holes at a vertical depth of approximately 400 metres below surface, in close proximity to and associated with geological units both above and below the Whin Sill intrusive.

Commenting on the resumption of exploration drilling, John Kearney, Chief Executive Officer of Minco said, "We are very pleased to be able to resume drilling on this exciting project. We originally believed we would only have access during the winter months, however with the cooperation of landowners and local County Councils we have found solutions to ensure on-going exploration activity."

The phased preliminary exploration programme is designed to test Minco's conceptual model that zinc-lead mineralization may exist beneath the historical underground mine workings in the geological succession structures that lie beneath the Great Limestone geological formation.

THE NORTHERN PENNINE OREFIELD - A RICH HISTORY OF MINING

The Northern Pennine Orefield covers an area of approximately 350 square miles and has a significant past production of lead, zinc, barite and fluorite. It is the second largest occurrence of zinc-lead mineralization in the British Isles after the Irish Midlands, and was the primary production area for zinc and lead mineralization in Europe during the early part of the twentieth century. Mining in this area ceased prior to the Second World War.

Mining in the area was via adits and was confined to the Great Limestone geological formation and the adjacent sandstone units, generally located at a depth of about 150 meters and about 450 meters above the base of the Lower Carboniferous succession, which in the midlands of Ireland, hosts the extensive Irish lead-zinc ore field, and six successful lead-zinc mines and numerous other mineral deposits.
