Hi George, It's not a question of good or bad, it's more of a geological surprise for me! Most magmatic Ni/Cu/PGE deposits of the type found in Ungava are the result of magmatic segregation of sulphides at the bottom of shallow flat intrusion(sills) or flows of ultramafic rock (Kambalda type). But, according to the author of the paper, the «South Raglan Trend» can be interpreted as a series of «en echelon» or parallel dikes. Much more similar to deposits found in the Jinchuan mining camp in the province of Gansu, China. Also, the dykes were intruded at the end of the tectonic evolution. Usually, ultramafic rocks of this type occur at the beginning of the cycle, not at the end! But as long as there are sulphides, I am happy. JP
