Ann: LiDAR Survey further enhances Equador Niobium Project, page-171

Fact is that because these samples have been hand sorted (the darker minerals being hand sorted from the quartz and feldspar) means they are not rock chip samples. They are processed samples with a heavy bias, basically a concentrate. This has been pumped harder than a pro but it looks like a house of cards to me. How many dark minerals can you see in the rock mass from Pedro's photo shoot? If you are not one of the uprampers here then the answer is not a great amount. Furthermore it occurs as veinlets so the volumes of potentia Niobium and Tantalum bearing minerals looks to be tiny. Dyor and have a good weekend.
