comments re viability aspect

Some people on this forum have expressed that the results may not be a complete write off and that perhaps a commercial venture may yet eventuate. Like myself I can appreciate that there are probably people on this forum who don't want to be burnt and live in hope that it's not yet game over. The reality with myself is that I really don't know where you draw the line with regard to what Fe grading is commercially viable and what grading is not. I appreciate people on this forum have their various opinions but is there anyone on this forum who has some "firsthand experience/knowledgeable understanding" re Fe grades to give a realisitic comment on the grades and whether there may or may not be any commercial merit in mining Nameless ?
