Mineral Deposits Limited: Measured and Indicated Resource Estimate for Grande Cote Zircon and Ilmenite Project MELBOURNE, AUSTRALIA--(Marketwire - May 7, 2009) - Mineral Deposits Limited (TSX:MDM - News; ASX:MDL - News) During the first quarter of 2009, Measured and Indicated Resources for the Diogo-Fass Boye area where MDL has completed infill drilling were estimated by AMC Consultants Pty Ltd. The resource estimate was provided at a series of cut-off grades and for a series of depths below the water table applicable to MDL's stated intention to mine the resources by cost efficient dredging. The MDL infill drilling was undertaken on lines at 200 metre intervals and with the majority of drill holes at 25 metre spacing. The drilling was a combination of RC (air core) using in-house Bombardier-mounted drill rigs and hand auger using a conventional DORMER shell auger. Overall, MDL completed 75,578.2 metres of RC and 32,677.6 metres of hand auger drilling over a strike length of some 23 kilometres. The granted mine lease is about 107 kilometres long. The results from this drilling were combined with previous RC and hand auger drilling in MDL's possession to provide a comprehensive database for the AMC resource estimate. The company has completed its initial mine planning based on these Measured and Indicated Resources:
