ASX Announcement

DRILL RESULTS FOR THE ROSE MINE PROJECT IN NEVADA.
Elevated gold intercepts in 3 of the 10 holes drilled
Elevated arsenic plus associated Carlin-style indictor
elements intersected in several holes
Low level silver intercept in one hole
The Directors of Navaho Gold Limited (Navaho Gold) are
pleased to advise that final assay results have been received
from drilling at the Rose Mine Project in Nevada, USA.
The Rose Mine Project is located in the Eureka Mining
District on the Battle Mountain Trend (see Figure 1) 13km
south west of the Ruby Hill/Archimedes deposit
(2.23Moz)(1) owned by Barrick Gold Corp. The
area is the subject of a farm-in agreement with Renaissance
Gold Inc (TSX-V:REN) under which Navaho can earn a 70%
interest in the project.
Assay results have been received from the 1,512m
(4,961') of drilling in 10 reverse circulation drill
holes completed during September/October 2011. Drill hole
locations are shown in Figure 2. Drilling was designed to
test both a near-surface gold intersection of 44m grading
0.26 g/t Au from
24m depth, defined in drill hole AR07-02 drilled by a
previous partner of Renaissance Gold, and several soil
geochemical and geophysical (both gravity and magnetic)
anomalies defined by Navaho Gold work.
Three (3) of the 10 holes intercepted anomalous gold (Au >
0.05ppm) as listed in Table 1. Anomalous arsenic (As >
30ppm), along with elevated antimony (Sb), barium (Ba),
bismuth (Bi) and thallium (Tl) was also intersected in
several holes and may indicate proximity to Carlin-style
mineralisation. Anomalous silver (Ag > 1g/t) was also
intercepted in hole RM11-06 (see Table 1).
RM11-01 was drilled to test the historic low grade Au
mineralisation in AR07-02 but did not intersect similar
mineralisation and it is interpreted that faulting has
off-set the known mineralisation to the south.
Of interest are the As intersections in drill hole RM11-09 of
30.5m @ 50ppm As from 83.8m and
9.2m @ 201ppm As from 134.1m as, in the Carlin model, these
may represent haloes to nearby gold mineralisation. RM11-09
was terminated at the base of the second As intersection due
to a lack of sample return and poor ground conditions so the
full depth extent of this zone of As anomalism could not be
tested.
A full review integrating the anomalous geochemistry and
alteration returned from this drilling with the existing
surface geochemistry and geophysics is underway to determine
if any near-miss scenarios can be identified which may
warrant further drill testing during the next season.

Table 1. Rose Mine - Summary of anomalous gold and silver drilling assay results
Notes
Drill samples are collected via cyclone assembly with rotary
wet splitter and analysed in 5' (1.5m) intervals. Gold is
analysed by 30g fire assay and an ICP-AES analysis. Silver is
analysed by four acid digestion and an ICP-AES analysis. All
of the analytical work is being performed by ALS Minerals,
North American laboratories. Sufficient commercially prepared
standards, blanks, and duplicates are inserted to assure
quality analytical results.
"Anomalous" indicates a result which is greater than 50ppb Au
(0.050 g/t) and 1ppm Ag (1.0 g/t). Holes or intercepts not
meeting these criteria are not listed. The foregoing
intercepts are not necessarily true widths as at this time
there is insufficient data with respect to the shape of the
mineralization to calculate its true orientation in space.

About Navaho Gold
Carlin Style Mineralisation
Navaho Gold is clearly focused on the exploration for and ultimate development of "Carlin Style" gold mineralisation. "Carlin" gold mineralisation was recognised near the town of Carlin in Nevada USA in the
1960's. Carlin deposits occur as the result of low temperature solutions precipitating gold, silver and sulphide
minerals in limey, magnesian and carbonaceous sediments, which have first been made a porous and receptive host by the effect of acid solutions emanating from nearby intrusions and fragmentation from fault activity. Carlin orebodies are typically both large and high-grade, ranging up to 40Moz gold (eg. Barrick Gold Corporation's Post-Betze deposit)1. Nevada has 20 major mining operations producing in excess of 100,000 oz gold per annum2.
Projects in Nevada and Queensland
Navaho Gold has various agreements to earn majority interests in, or acquire, at Navaho Gold's election, seven projects in Nevada, four of which are located on or adjacent to the prolific gold-producing Carlin and Battle Mountain Trends, and holds exploration licences over three potential new "Carlin" style regions in Queensland.
From the period 1981 to 2009, in excess of 156Moz gold has been produced in Nevada, making it one of the most strongly endowed gold provinces in the World2. The Carlin Trend alone has produced more gold than any other mining district in the USA3.
Importantly, Navaho Gold's Carlin East project in Nevada lies approximately 5km east of Barrick Gold Corporation's 40Moz gold Post-Betze deposit, and the Utah Clipper project in Nevada is located immediately along trend from Barrick's Cortez and Pipeline-Gold Acres deposits which contain more than 30Moz gold3.
