Description
M1
9
Main 1
: This is the main domain of mineralization with the best continuity, the
widest veins, and the highest REE grades. It is characterized by strong, near
vertical, high-grade veins with excellent continuity and a NW-SE trend. As it
continues to the northwest it splits into 3 zones, of which the west-most branch
is interpreted as the continuation of Main 1. The Main 1 Zone contains high-
grade mineralization in a vein/dike with widths of 20 to over 100 feet that is the
focus of mining during the first 9 years of production.
M2
6
Main 2
: This is the center of the three branches off of Main 1. Mineralization is
not as continuous nor as high grade as Main 1 or Main 3. The northwestern
extension of Main 2 is poorly drilled, but appears to be mostly barren, although
there may be a weak connection to Whitetail to the northwest.
M3
8
Main 3
: This is the eastern-most splay off of Main 1. High-grade, near-vertical,
north-south trending veins are present, but are narrower and less continuous
than in Main 1, but more continuous than Main 2.
East
7
East
: The East domain is located just to the east of Main 1 and terminates to
its northwest on Main 3. The predominant mineralization is a single, narrow
vein with a strike length of over 1000 feet that is sub parallel to Main 1.
NW
1
Northwest Bull Hill
: Veins in this area are much less continuous than veins in
the Main, East, and West 1 domains. Veins appear to strike about N15E and
dip 65° to the NW. Continuity is poorly defined.
SE
10
Southeast
: The Southeast Domain terminates the Main 1, West 1, and East
domains on their southeast limits. This domain is defined by a sudden
decrease in the intensity of REE mineralization across a discontinuity that dips
approximately 80 degrees to the northwest, and strikes approximately N55E.
The details of the discontinuity are not understood, but it may be a fault or
intrusive contact.
W1
5
West 1
: West 1 is immediately adjacent and similar to Main 1. Veins in West 1
are thinner, lower grade, less continuous, and more widely spaced.
W2
2
West 2
: Mineralization in West 2 is poorly defined by only a few drill holes. It
appears to be less continuous than West 1, and may trend more north-south
than northwest-southeast.
WT1
3
Whitetail 1
: This area is defined by only limited drilling. A single strong north-
south striking vein is defined by the drilling.
WT2
4
Whitetail 2
: Mineralization in Whitetail 2 strikes northwest-southeast. Although
total REE grades are not as high as in Main 1, the grades of the more valuable
heavy REEs are significantly higher than Main 1.
