Lithology Comments

Jun 13, 2011 (A Wilson) - Apatite-rich veins and patches are hosted in syenitized calc-silciate gneiss, biotite gneiss, meta-arenite and scapolite skarn. The mineralization occurs in veins and dikes, but also in pegmatitic patches with or without hornblende-micocline.

Mineralization Comments

Jun 13, 2011 (A Wilson) - Apatite occurs as massive aggregates and euhedral crystals, green to brown to red-brown in colour. Selected samples collected from the site returned Mn values ranging from 1250 ppm to 1440 ppm. Sample AF14-2 returned 1500 ppm Sr (spec.), 2000 ppm La, 3500 ppm Nd and 1880 ppm Ce. Sample AF14-7 returned 1890 ppm Zr, 140 ppm U3O8, 540 ppm Th, 10 ppm Rb, 150 ppm Yb, 15 ppm Sc, 700 ppm La, 6000 ppm Nd, <100 ppm Eu, 5000ppm Ce. Sample AF14-8 returned 330 ppm Zr, 9 ppm U3O8, 80 ppm Th, <10 ppm Rb, 20 ppm Yb, 15 ppm Sc, <100 ppm La, <100 ppm Nd, <100 ppm Eu, 460 ppm Ce. Grab samples of apatite collected by Sharpmin in 1996 returned Yt values of 4335 ppm, 495 ppm, 455 ppm and 2620 ppm. Grab samples of apatite collected by Harper in 1993 returned Fe values ranging from 782 ppm (sample 3b) to 3345 ppm Fe (sample 5a); Mn values ranged from 234 ppm to 382 ppm. Grab samples of apatite collected by Harper in 1993 returned 9255 ppm Fe, 170 ppm Mn, 158 ppm Dy, 291 ppm Sm, 2304 ppm La, 79 ppm Yb.
