Azimuth measurements are corrected to true north using appropriate magnetic
declination for the period of drilling, as determined by the NOAA declination
calculator. In general, very minor dip deflections were recorded in the 2010, 2011,
and 2012 drill holes. Deflections were generally no more than several degrees
upward or downward, but ranged up to 10 degrees in 2009 over 1000 feet (300 m).
Lateral deflection was typically less than 5 degrees, but ranged up to 10 degrees over
1000 feet (300 m) in 2009.
In the 2013 drilling, azimuth deviation was generally 5 degrees or less for 11 of 14
HQ drill holes at Whitetail Ridge, based on the first survey at a depth of 100 feet.
However, three of the HQ holes showed azimuth deviation of 6 – 10 degrees.
Azimuth deviation in the PQ holes at Bull Hill was generally less than 2 degrees and
never more than 3 degrees, based on the results from the first survey at a depth of
100 feet. Inclination deviations ranged from less than 3 degrees to a maximum of 6
degrees.
10.3.5 Summary of Drilling Results
The evaluation of the drill data is ongoing. All core holes drilled and assayed between
2009 and 2013 were evaluated and included by ORE in the current resource estimate
update. True thicknesses of the drill intercepts are estimated from cross sections and
3D modeling of the mineralized zones. The 261 core holes completed by Rare
Element (not including bulk sample drill holes) confirm and expand the extent of the
known rare earth mineralization (Figure 8.2). This drilling expands and better defines
the historic resource originally identified by Hecla (Wineteer, 1991), as well as the
resource estimates completed for the Company by O.R.E. and reported in a series of
news releases from 2009 to 2013. To date, the drilling allows for delineation of
Measured, Indicated, and Inferred resources in the Bull Hill deposit, additional
Indicated and Inferred resources in the Whitetail Ridge deposit
,
and Inferred
resources in the Bull Hill NW deposit.
