This article was on The Australian website today, talking about the drop in iron ore price in the last few weeks. What caught my eye was at the bottom an analyst in London describing Mamba's recent drilling results:

"The news that Mamba has intersected a significant zone of hematite mineralisation with a 275m [change that to 303m and still in mineralisation] intersection potentially means Mamba may be on the verge of delineating the largest DSO deposit within the Labrador Trough".

I checked up on some of the other DSO deposits in the region and the biggest are in the order of New Millenium's and Labrador Iron's deposits of between 50-60 Mt.
