Results of Runruno sampling

Metals Exploration PLC 13 June 2005 IMMEDIATE RELEASE 13 JUNE 2005 METALS EXPLORATION PLC Runruno Project - Final results of channel sampling of Tunnels Highlights • Final results received from extensive channel sampling of local miners' tunnels at Runruno Project have returned average grades of 4.3 g/t gold; 1,125 g/t molybdenum and 4.8 g/t silver. • Local tunnels (fifty tunnels in total) sampled occur over a distance of approximately 2 kilometres • Diamond core drilling anticipated to commence early next month The Company has now received the last batch of results from its recent underground tunnel sampling program. The Company is very encouraged by these results and looks forward to the commencement of a drilling program early next month. Results of mapping and sampling of the local miners' tunnels located at the Balcony 1, Balcony 2, Main Runruno, Tayab and Malilibeg areas have confirmed the existence of the high grade (>1.4g/t Au) potential of gold mineralisation (and molybdenum) in the hangingwall and footwall zones of the main Runruno mineralisation. A description of how the samples were taken, and what they represent, was provided in the Company's recent news release dated 27 May 2005. Generally, 5 metre channel samples were taken continuously along the side walls and backs of the local miners' tunnels. Results of the channel samples represent the grades of the high-grade material that the local miners have been leaving behind. the channel samples (315 samples) taken from fifty tunnels have returned average grades of 4.3 g/t gold; 1,125 g/t molybdenum, and 4.8 g/t silver. -------------------------------------------------------------------------------- Tunnel No. of Tunnels No. of Au Mo Ag Locations sampled Samples g/t g/t g/t -------------------------------------------------------------------------------- Balcony 1 7 50 5.7 754 3.7 -------------------------------------------------------------------------------- Balcony 2 1 14 5.5 978 5.2 -------------------------------------------------------------------------------- Main Runruno 5 42 3.1 420 2.3 -------------------------------------------------------------------------------- Tayab 19 100 4.5 1060 4.5 -------------------------------------------------------------------------------- Malilibeg 18 109 3.9 1642 6.6 -------------------------------------------------------------------------------- Totals 50 315 samples -------------------------------------------------------------------------------- Weighted Average Grades 4.3 1,125 4.8 -------------------------------------------------------------------------------- The local miners' tunnels are located predominantly in the hanging-wall or foot-wall zones of the main Runruno mineralisation, which has been mapped at surface over a strike distance of 2.5 kilometres. The local miners' tunnels occur over a distance of approximately 2 kilometres. Forward Looking Statement The Company's objective is to determine a gold (+molybdenum) resource over a 600 metre strike, 100 metres width to a down-dip depth of 400 metres. Given these parameters, the Directors are setting a resource target for this part of the deposit of 45 to 55 million tonnes. This is a forward looking statement and should not be regarded as anything else and should not be regarded as a true indication of the resource until it has been properly explored.
