7.5.5 Stockwork Mineralization
The stockwork mineralization consists of zones of intersecting veins and veinlets that
tend to occur as envelopes along and between larger FMR/carbonatite veins and
dikes. Stockwork-type mineralization is common in all of the REE mineralization types
summarized in Table 7.2. Individual veinlets can range from sub-millimeter to meter
widths and exhibit either random orientation or orientation sub-parallel to the major
dikes and veins. REO grades in the stockwork mineralization tend to be lower than in
the dikes and larger veins, with a range between approximately 0.5% and 3% TREO.
Vein densities vary widely, with higher vein densities and abundance of contained
vein material generally corresponding to higher REO grades within a given stockwork
zone. The stockwork style of mineralization contributes significantly to the contained
REO resource in the Bull Hill, Bull Hill NW, and Whitetail Ridge resource areas, and in
the Carbon and East Taylor target areas. Recognition and quantification of this
category of mineralization will be an important component in the mine grade control
