HIGHLIGHTS
�� Diamond drilling at the Sambung prospect identifies broad
zones of gold mineralisation

SAMDD061: 8m @ 2.60 g/t Au from 0m
21m @ 5.36 g/t from 27m
�� Geological model confirmed; indicates exploration upside
�� Further drilling to test down – dip extent of high grade zone
this quarter

Oropa is pleased to announce further encouraging drilling
results from its Sambung prospect, North Sumatra, Indonesia.
The completion of over 5000m of diamond drilling at Sambung
by Oropa has enabled the exploration team to complete
detailed geological modelling of the central portion of the
Sambung prospect. Modelling indicated the presence of a
core zone of high grade gold mineralisation, which was tested
by the completion of holes SAMDD054, 55, 56, 59 and 61; all
of which intersected strong zones of gold mineralisation within
predicted zones. Additional holes were designed to close off
mineralisation on selected drill sections.
Gold mineralisation at Sambung predominantly occurs as a
blanket of shallow-dipping siliceous jasperoid that formed at or
near the unconformity contact between older Permian
limestone and younger Tertiary sediment. Mapping, drilling
and geological interpretation strongly suggested the presence

DRILLING REVEALS HIGH GRADE GOLD ZONE AT SAMBUNG

of a high grade primary “feeder zone” of gold mineralisation that had until now
remained elusive or unrecognised. High grades discovered in these recent holes are
associated with a structurally-controlled jasperoid hydrothermal breccia, dipping
steeply back towards the south west and trending north west. Additional diamond
drilling will test the down dip extent of this mineralised zone and will also endeavour
to follow the strike extent of the structure beyond late – stage cross cutting faults that
disrupt the sequence.

Notes
1. All Au assays determined by 50gm fire assay with AAS finish by Intertek- Caleb Brett Laboratories of
Jakarta
2. Lower cut of 0.5ppm Au 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. Quality Assurance and Quality Control (QAQC):
Gold intersections reported have been verified by the company’s QAQC protocols, which include
routinely inserted standards. All samples from drill holes are prepared by Intertek-Caleb Brett and
pulverised to 90% passing 75 microns then analysed for gold using Fire Assay methods
Oropa is advancing exploration activities at Sambung towards the completion of a
preliminary resource calculation this quarter. Step–out drilling will also be
undertaken to assess the strike extent of identified jasperoid gold mineralisation
towards grid east.
