Melbourne, Feb 13, 2009 AEST (ABN Newswire) - Mantle Mining Corporation Limited (ASX:MNM) is pleased to report that it has recently defined a number of parallel major shears containing high grade Gold and Silver values adjacent to existing drill indicated shear-hosted gold mineralisation at its 100% owned Granite Castle Gold Project in north Queensland.
The shears identified to date are exposed at surface and in close proximity to the Company's existing JORC resource. Significantly, drill holes completed to date have consistently confirmed the presence of shear-hosted gold mineralisation below mineralised surface outcrops. A review of drilling data, combined with the results from recent prospecting and soil sampling with a portable XRF analyser, have shown extremely good correlation of anomalous geochemistry, including gold and silver, with recognised shear zones.
The best historic drilling results include 5.8 g/t gold over 5m from 34m depth, 13.7 g/t gold over 2m at 11m depth and 25.5 g/t gold over 1m at 139m depth. To date there are in excess of 7 line kilometres of mineralised shears defined by reconnaissance prospecting and rock chip sampling that are only partially tested by drilling. This is significant given that the mineralisation making up the current JORC resource base is contained in a 600 metre length of the Granite Castle shear. Mantle remains confident, from work completed so far and the available lengths of partially drilled mineralised shears, that it should be possible to fast track evaluation of the shear system with a view to drilling out a number of the best shears in 2009 and subsequently deliver a major expansion of the gold resource base at Granite Castle.
