- 2.28 opt (78.03 g/t) Gold over 15.8 ft (4.8 m) in hole N07U050
- including 4.66 opt (159.71 g/t) over 5.9 ft (1.8 m)
- 1.47 opt (50.28 g/t) Gold over 16.5 ft (4.0 m) in hole N07U052
- Results pending for 80 additional underground holes
- Results pending for 7 additional surface holes
- Geological re-assessment work 55% complete; resource update Fall 2010
Because the 2007 and 2008 results were not formerly reported, a careful review was initiated by Fire River of all quality control and quality assurance procedures used by the former operator. Although original check assays from the 2007 drill program were not documented, it is clear, however, that certified standards were used. The re-sampling program of the 2007 drill core is essentially a modified field duplicate exercise of the original assay results.
The re-sampling of the remaining half-cores, were fully analyzed except in rare cases where quarter-cores were used. Sampling of core-duplicates as compared to FAU's pulp-duplicates can produce a high degree of variability in the results due to the "nugget effect" of gold mineralization that occurs at Nixon Fork. This nugget effect was clearly evident in the bonanza grades reported for the 2008 drilling.
Every effort has been made to replicate the previous sample intervals except when a previous sample crossed a lithological or mineralized boundary. In these cases the new 2010 samples were terminated at such boundaries.
The differences in lengths of the intervals may account for some of the variability in gold grades. In general, the assays are in conformity, especially for a comparison of field duplicate samples in a high-grade, coarse gold system.
Table 1 illustrates the most recent significant intercepts for drill holes relogged and sampled during this program. These drill holes were completed in the Crystal decline around the 3300 zone near the 220 ft level.
Table 2 illustrates a comparison of the 2010 reassay field duplicate samples. In general, the results match up very well.

The differences in grades shown are typical of high grade, gold deposits with a significant nugget distribution.
For additional details, please refer to FAU's April 20th March 23rd and March 31st press releases, which includes the results from the first 33 holes, the geological re-assessment program, historic site production, a description of the deposits, additional information on the QA/QC measures and a description of our planned 2010 exploration drilling program.
The Nixon Fork project produced significant bi-product copper and silver. Until the closure of the mine in 2007, reported copper production was 1,273,066 lbs and silver production was 19,566 ounces from 106,137 tonnes mined. Historic recovered grades are about 0.6% for copper and 0.18 opt for silver.
The project is being managed by Richard Goodwin, P.Eng, VP Mining for Fire River Gold and is the Qualified Person for this news release.
