Medusa Mining Limited through its Philippines subsidiary, Philsaga Mining Corporation, is providing an update on its portfolio of copper prospects. This report is an update from the announcement dated May 7th 2010.

Additional prospects have been added in the Tambis District, the Sawahon prospect where reconnaissance outcrop samples returned to 0.44 % Cu and 0.10 gram per tonne gold in favorably altered diorite and the Lower Bananghilig prospect where reconnaissance samples in stock worked volcanics returned 0.16% Cu and 0.35 gram per tonne gold as discussed in the announcement dated May 10th 2011.

Work during this financial year to June 30th 2011 focused on mapping and relogging of core for Kamarangan and Lingig, mapping and ridge and spur soil sampling at the Sawahon prospect.

An extensive program of Induced Polarization and resisitivity geophysics totaling approximately 186 line kilometres in conjunction with ground magnetics commenced on May 2nd 2011 to cover the Sawahon to Supon zone and the Kamarangan, Usa and Lingig prospects prior to further drilling which is being planned for the 2011 ton 2012 financial year.

Mr Geoff Davis MD of Medusa Mining said that "The portfolio now comprises nine copper targets and other copper occurrences. Whilst no drilling has been undertaken since February 2010 we have been working steadily to increase our knowledge of the Linigig, Usa and Kamarangan prospects while mapping has discovered several new outcropping copper areas including the Sawahon and Lower Bananghilig prospects. The IP program and ground magnetics will assist to delineate and prioritize drill targets for drilling during 2011 to 2012.
