Mar 07, 2011 (C Ravnaas) - A significant occurrence of Rare Earth metals was discovered on the English River during prospecting for uranium. Five grab samples were taken from a rusty-weathered pegmatite in contact with amphibolite. The potential for this zone has not been evaluated. (Reference Quest Uranium Kenora Assessment File 52L07SE V-1 AFRO # 2.40813).
Dec 03, 2014 (C Ravnaas) - Five (5) samples from moderately radioactive rocks returned slightly anomalous uranium values, the highest being 107 ppm U3O8. The radioactivity appears to be caused by thorium, which averages 2690 ppm Th for 5 samples. Total REO content is over 2 percent for the five samples. Lanthanum (La) and Cerium (Ce) in all five samples total over 1% (up to 10000 ppm La and Ce). Nd and Sm content averages 2512 and 395 ppm respectively for the five samples. Terbium is also present (30 ppm). Yttrium (Y) results up to 604 ppm Y. The metal ratios and the high content of phosphorous suggest the presence monazite as a source mineral, although apatite may be present.
