Sydney, Jan 28, 2010 (ABN Newswire) - Dynasty Metals Australia Limited's (
ASX:DMA) Stage 2 Reverse Circulation (RC) drill holes, MMRC016 to MMRC029 were designed to get a better understanding of the mineralisation in Marra Mamba. The final results from these holes are presented in Table 1 (see bottom of release). These results confirm that the intercepts of Marra Mamba Iron Formation to date have been iron-rich with calcined in-situ grades ranging from 55% Fe to 65% Fe, and showing low concentrations of phosphorous, typically 0.04% to 0.07% P.
The results demonstrate Dynasty's early exploration success by confirming with drilling the presence of strongly mineralised sections of the important Marra Mamba Iron Formation up to 100m thick and with a shallow dip to the west. These results provide confidence for future exploration for Marra Mamba on Dynasty's tenements.

About Dynasty Metals Australia Limited
Dynasty Metals Australia Ltd (ASX:DMA) is an emerging Australian iron ore exploration company focused on developing its 100%-owned tenements at Prairie Downs in Western Australia's Pilbara region.
In March 2010, Dynasty announced initial JORC-Compliant Inferred Resources of 453 million tonnes of Detrital Channel Iron and 23.3 million tonnes of Marra Mamba Iron Formation.
The 2010 exploration programs are underway and are aimed at further testing and significantly expanding the current resources, as well drilling a large iron-rich basal conglomerate for the first time. The exploration target is more than 1 billion tonnes of iron.
During 2010, Dynasty plans to commence detailed commercial investigations that will cover preliminary mine planning, beneficiation process design, mining and processing costs, transport infrastructure, capital costs, environment and native title clearances, and government approvals. A pre-feasibility study is anticipated to commence in late 2010.
