Drilling Success at Sihayo 1 Prospect
HIGHLIGHTS
• Broad-spaced reconnaissance diamond drilling of the Sihayo
1 prospect area discovers gold mineralisation
• Results of the first 6 drill holes drilled and assayed include:
�� SHDD067: 4m @ 4.09g/t Au from 3m (including 1m @
8g/t Au from 4m)
�� SHDD068: 5m @ 2.1 g/t Au from 7m
• Mineralisation at Sihayo 1 is associated with intense
hydrothermal alteration, consistent with the nearby Sihayo 1
North deposit (610,000 Oz Au Inferred Resource)
• Sihayo 1 prospect is located midway between the Sihayo 1
North deposit (approximately 1km to the north) and the
Sambung prospect (approximately 1km to the south east)
• Drilling of the Sihayo 1 mineralised system continues to test:
�� The lateral extent and depth of mineralisation
�� The possibility of mineralisation extending towards
both Sihayo 1 North and Sambung
Oropa is pleased to announce drilling success at the Sihayo 1 North
prospect, located within the North Block of its 75% owned Pungkut
Project, North Sumatra, Indonesia (Fig 1).
Drilling encountered shallow gold mineralisation in intensely silicified,
hydrothermally altered volcaniclastic and limestone. Gold
mineralisation at Sihayo 1 occurs as sub-horizontal zones of jasperoid
silica, developed within Permian lithology (usually limestone) at the
contact with younger Tertiary sedimentary cover. The cover is
generally not mineralised.

The style of mineralisation at Sihayo 1 appears to be very similar in nature to, and may
represent a direct extension of the Sihayo 1 North deposit.
Initial Drill results include:
SHDD067: 4m @ 4.09g/t Au from 3m (including 1m @ 8g/t Au from 4m)
SHDD068: 5m @ 2.10 g/t Au from 7m
SHDD069: 6m @ 1.42g/t Au from 8m
SHDD070: 6m @ 1.72g/t Au from 8m
SHDD071: 9m @ 1.02g/t Au from 43m
These drill holes, completed on 100m x 100m centres, are designed to assess the lateral
extent of hydrothermal alteration and the thickness of Tertiary sediment cover. The
results confirm that the hydrothermal alteration zone persists over a wide area, and that
the Tertiary cover is significantly shallower than initially thought (Fig 2).
The current drill programme at Sihayo 1 is ongoing and will test an area of approximately
800m x 500m, with infill and extensional drilling to be initiated depending on results.
Concurrently with the drilling programme at Sihayo 1, Oropa has two drill rigs operating
at the Sambung prospect some 1 km to the south east of Sihayo 1. Drilling at Sambung
is targeting high grade gold values encountered in earlier trenching and drilling.
Results from these programmes will be announced as they are received and evaluated.

Notes
1. All assays were determined by 50gm fire assay with AAS finish
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
5. All intervals reported as down hole lengths
6. Collar positions established by tape and compass traverse from surveyed benchmarks
7. UTM Zone 47 Northern Hemisphere
