Thanks for your response Piper. I read those sites you listed and am still a little confused. Based on what you posted below, if I had a chunk of Dronino in my hand, I could say it has a Nickel content of either 98.1%, 10.8% or 9.8%...I guess which one is dependent upon what part of the sample I'm referring to. So if I refer just to the Nickel content in the troilite its' about 98.1%. And the Nickel content in the rest of the Dronino is 9.8%, But combined it comes out to 10.8%. Is my understanding correct?

Chemistry : A bulk Dronino sample analyzed by INAA in UCLA contains: Ni 98.1, Co 5.54 (mg/g), Cr 37, Cu 32, Ga <0.3, As 3.52, W 0.38, Ir 1.68, Au 0.284 (ppm). The average of EMP analyses of the metal is 10.8 wt% Ni. The higher Ni concentration relative to the INAA data can be explained by the presence of troilite in the bulk sample. Dronino has about 10 vol% troilite, enough to significantly skew the bulk nickel content (9.8%) relative to that in the metal (10.8%). **************A Good Credit Score is 700 or Above.
