package were analyzed using lithium metaborate fusion with an ICP/MS finish
(ActLabs code 4B2-STD), and Au was analyzed by 30-gram fire assay with a neutron
activation finish (ActLabs code 1A1). Quality control for the ActLabs assay data were
monitored with blanks and standards provided by the analytical laboratory. None of
these assays are currently being used for resource estimation. The 2007 and 2008
drill hole data were replaced with more reliable information from the 2009 through
2013 drill programs.
11.3.6 2009 Assaying
Pulps were prepared by Minerals Exploration Geochemistry of Reno, Nevada from
the 2009 drill core samples and sent to Activation Laboratories of Ancaster, Ontario,
Canada for assay. Sets of standards, blanks, and duplicates were inserted to monitor
analytical quality. The samples were analyzed for REE, Au, V, Cr, Co, Ni, Cu, Zn, Ga,
Ge, As, Rb, Sr, Zr, Nb, Mo, Ag, In, Sn, Sb, Cs, Ba, Hf, Ta, W, Tl, Pb, Bi, Th, and U.
The REE include La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y. The
REE and multi-element geochemical package were analyzed using lithium
metaborate fusion with an ICP/MS finish (ActLabs code 4B2-QUANT). Gold was
analyzed using a 30-gram fire assay with atomic absorption finish (ActLabs code
1A2). Over limit REE assays were completed as part of the 4B2-STD-QUANT
analytical package.
11.3.7 2010-2011 Assaying
The 2010 and 2011 drill samples were prepared by Minerals Exploration
Geochemistry of Reno, Nevada and sent to ALS in Vancouver, Canada for assay.
Sets of standards, blanks, and duplicates were inserted at regular intervals to monitor
analytical quality. The samples were analyzed for REE, Sn, Ta, Tb, Th, U, W, Zr, and
Au. The REE include La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y.
The REE and multi-element geochemical package were analyzed using lithium
metaborate fusion with an ICP/MS finish (ALS code ME-MS81h). Gold was analyzed
by 30-gram fire assay with an ICP/AES finish (ALS code Au-ICP21). Over limit REE
assays were analyzed using a lithium metaborate fusion followed by ICP/AES finish
(ALS Code ME-OGREE). Quality control for the ALS assay data was monitored using
blanks and internal standards provided by Rare Element through MEG, and by
selected duplicate analyses. Preparation of the Bear Lodge Project internal standards
is discussed in Section 11.4.
