Intrepid updates drilling result from E. Java gold project

GTD 58 was drilled within the central portion of Zone B on an azimuth of 270 degrees. The hole was collared near historical hole GTD 5, which was drilled on azimuth 180 degrees (see diagrams below).
Results have also been received from 3 other holes drilled at Zone B - GTD 54, 55, and 57. Results from holes 59 and 60 are expected within the next few weeks. Drilling is continuing. Data review to plan additional drilling at Zone B south is also in progress.
Zone B is located 1 kilometre southeast of Zones A and C where an aggregate inferred oxide resource of 2.57 million ounces gold equivalent (gold + silver) has been estimated.
In addition to the near surface oxide gold-silver mineralisation the drill holes at Zone B have intersected high sulphidation copper-gold-silver mineralisation below approximately 200 metres from surface (see figure below). This is significant and provides encouragement for future deeper drilling at Zone B to define high sulphidation and porphyry related copper-gold-silver mineralisation similar to that intersected in deep drilling near zones A and C.
Results from hole GTD 58 are,
Oxide mineralization
24-88 metres: 64 metres at 2.65 grams per tonne gold, 17.2 grams per tonne silver, 2.91 grams per tonne gold equivalent. Including 36-58 metres: 22 metres at 6.43 grams per tonne gold, 15.9 grams per tonne silver, 6.67 grams per tonne gold equivalent.
High Sulphidation mineralization
248 - 292 metres: 44 metres at 0.11 grams per tonne gold, 0.31% copper, and 13.3 grams per tonne silver
310 - 338 metres: 28 metres at 0.22% copper, 1.5 grams per tonne silver.
The high grade oxide gold-silver results from hole GTD 58 are consistent with intercepts from the historical hole GTD 5
GTD 5 - Oxide mineralization
25.1 - 82.1 metres: 57 metres at 0.71 grams per tonne gold, 6.5 grams per tonne silver, 0.81 grams per tonne gold equivalent
106.1 -193.1 metres: 87 metres at 1.8 grams per tonne gold, 13 grams per tonne silver, 2.0 grams per tonne gold equivalent. Including 163.1 - 178.1 metres: 15 metres at 6.14 grams per tonne gold, 9.4 grams per tonne silver, 6.29 grams per tonne gold equivalent
Also of interest are anomalous results in historical holes 7 and 13 located approximately 400 metres to the northwest of holes GTD 58 and 5. Anomalous gold and silver values in the oxide zone of these holes suggest that the margins of the Zone B oxide mineralisation may locally extend beyond the limits suggested by surface gold anomalism in soil samples, thus further expanding potential target areas.

The deeper high sulphidation zone is clearly shown by elevated copper depicted by the green histograms.(end of edited release)
