Dynasty Metals Australia Limited (ASX:DMA) Announce Continuation Of High Grade Iron Ore Mineralisation At Marra Mamba Prospect
Sydney, Jan 28, 2010 AEST (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.
