Release: Oropa: More mineralisation at Sihayo

Tuesday, 26 April 2005 ? Oropa Limited is pleased to announce the intersection of additional gold mineralisation at its Sihayo 1 North deposit, North Sumatra, Indonesia.

Drill hole SHDD052 intersected two zones of hydrothermal breccia hosted mineralisation below shallow Tertiary sediment cover. This hole was designed to test for shallow-dipping mineralisation near the unconformity between upper, younger Tertiary sediments and a lower limestone unit, and to provide material for metallurgical test work.

SHDD052 intersected two zones; 7m @ 2.73 g/t Au from 28m and 8m @ 2.83 g/t Au from 44m.

This follows the excellent results from hole SHDD051, which returned 24m @ 2.78g/t from 4m, including 6 metres @ 5.2g/t from 22m, announced on the 13th April 2005.

Drill Hole Details
Hole: SHDD052
Northing:10,225
Easting: 54,950
Azimuth (mag): 040
Dip: -60
Depth (m): 156.5
From: 28 and 44
To: 35 and 52
M: 7 and 8
Grade g/t Au: 2.73 and 2.83

Notes:
1. All assays were determined by 50gm fire assay
2. A 0.5ppm Au lower cut was used
3. A maximum of 2m of consecutive internal waste (material less than 0.5ppm Au) per reported intersection
4. All interval grades were calculated as a weighted average

Drilling is ongoing, with results from new holes expected within the week.

Samples selected for metallurgical test work from SHDD051 have been collected and despatched to Independent Metallurgical Laboratories of Perth for processing. (end of release)
