BRISBANE, AUSTRALIA--(Marketwire - July 16, 2009) - Intrepid Mines Limited (TSX:IAU)(ASX:IAU) (the "Company") is pleased to report that ongoing diamond drilling in Zone B of the Tumpangpitu Prospect, Tujuh Bukit Project has continued to define some higher grade gold-silver oxide zones within a broad lower grade envelope.
The recent drilling has returned oxide intercepts including -
GTD-61 69-104m: 36m @ 0.71g/t gold, 26g/t silver, (1.11g/t gold-equivalent)
GTD-63 70-110m: 40m @ 1.42g/t gold, 37.10g/t silver, (2.00 g/t gold-equivalent)
GTD-64 82-128m: 46m @ 2.12g/t gold, 11.48g/t silver, (2.30 g/t gold-equivalent)
GTD-67 142-196m: 54m @ 1.62g/t gold, 15.89g/t silver, (1.86g/t gold-equivalent)
GTD-70 4-44m: 40m @ 2.10g/t gold, 5.4g/t silver, (2.18g/t gold-equivalent)
The first hole to be drilled into the southern portion of Zone B, GTD-69 (over the extension of the soil anomaly) has intersected -
GTD-69 4 - 18m: 14m @ 3.54g/t gold, 1.36g/t silver, (3.57g/t gold-equivalent)
GTD-69 38 - 52m: 14m @ 2.89g/t gold, 1.64g/t silver, (2.91g/t gold-equivalent)
Observed Brad Gordon, Intrepid's CEO, "The results emerging from Zone B are particularly encouraging for our Tujuh Bukit project as we find higher grade intervals over a large anomaly area of the Tumpangpitu Prospect. Zone B is developing as the largest area of mineralisation and has returned some of the highest grade defined to date in the upper oxide zone and separately from Zones A and C where we have already defined a combined Inferred resource of 2.57 million ounces of gold-equivalent. This is further enhanced by the relatively shallow, high quality, copper-gold-silver mineralisation we are still finding in the lower sulphide zone on which we have just announced the Heads of Agreement with Vale."
(See Intrepid news release dated June 9, 2009.)
The latest drilling in Zone B is also consistently defining relatively shallow sulphide copper-gold-silver mineralisation of grades comparable to that defined at depth under Zones A and C, located 1 kilometre to the North-West.
Significant deeper sulphide intercepts include -
GTD-57: 266-372m: 106m @ 0.19g/t gold, 17.88g/t silver, (0.47g/t gold-equiv) & 0.34% copper
GTD-58: 248-278m: 30m @ 0.14g/t gold, 19.33g/t silver, (0.44g/t gold-equiv) & 0.31% copper
GTD-62 252-314m: 62m @ 0.42g/t gold, 45.2g/t silver, (1.12g/t gold-equiv) & 0.47% copper
GTD-63: 182-196m: 14m @ 1.09g/t gold, 55.14ppm silver, (1.94g/t gold-equiv) & 0.22% copper
GTD-64: 216-250.2m (EOH): 34.2m @ 0.21g/t gold, 80.16g/t silver, (1.44g/t gold-equiv) & 0.24% copper
GTD-65: 298-336m: 38m @ 0.28g/t gold, 10.37g/t silver, (0.44g/t gold-equiv) & 0.44% copper
Detailed soil sampling at Zone B has defined a multi-element anomaly over an area of 300 metres x 1000 metres, twice the areal extent of similar anomalies at Zones A and C. This anomaly is the focus of ongoing drilling, with a second rig having been deployed during June.

Previously reported results from Zone B included 22m @ 6.35 g/t gold, 15.9 g/t silver (6.60 g/t gold-equivalent) from 36m down hole in hole GTD-58. In the same area, historical hole GTD-5 intersected broader lower grade intercepts surrounding 15m @ 6.14 g/t gold, 9.4 g/t silver, (6.29 g/t gold-equivalent) from 163.1m down hole.GTD-57 intersected 26m at 2.07 g/t gold-equivalent from 136m.
