Bonanza gold
grades from ali vein

prospect
·
Excellent
grades from diamond drilling at Hutabargot Julu Prospect (Pungkut Gold
Project):
HUTDD018: 5m @ 35.67 g/t Au from 47m,
including
2m @ 80 g/t Au from 47m
·
Latest drilling supports
the Hutabargot Julu exploration model, demonstrating the potential for
high-grade bonanza shoots developed within the extensive vein structures.
·
Regional potential
highlighted by the fact that Hutabargot Julu is one of 20+ targets identified
to date within the Pungkut Contract of Work.
Oropa Limited (ASX: ORP
– “Oropa”) is pleased to report a bonanza grade near-surface gold intersection from recent
drilling of the Ali vein in the
central part of the Hutabargot Julu prospect, located 5.5km south east of the
current 710,000oz gold resource at its 75%-owned Pungkut Gold Project in Indonesia.
The Ali vein
was discovered earlier this year by mapping and surface sampling, which
consistently returned anomalous gold with some high grades (maximum 136 g/t Au) from within an inferred
330m strike length. The vein is one of several high-grade vein systems within
the Hutabargot Julu area, where Oropa is a major high-grade epithermal gold
system.
Five diamond
drill holes have now been drilled at intervals along the Ali vein. Most holes
intersected narrow zones of stringer quartz veins and clay, with
low-to-moderate gold grades returned from these zones. However, where veining
is better developed, the gold grades increase, as highlighted by the
southernmost drill hole, HUTDD018,
which returned 5m @ 35.67 g/t Au
and 198 g/t Ag and 2m @ 80g/t Au from 47 metres from an
intersection that includes 1.3 metres
of colloform banded quartz vein.
Some of the
earlier drilling results from the Ali vein include:
HUTDD016: 2m @ 3.68 g/t Au from 18m
2m @ 3.62 g/t Au from 37m
HUTDD017: 4m @ 1.21 g/t Au from 71m
Another
drilling program is planned for Hutabargot Julu after a suitable rig is located
to test the high grade mineralisation at Ali, which is open to the south.
Further east, the Sarahan vein
remains a priority target due to the massive alteration over several kilometres
of strike length and potential to host a large scale resource. Drilling
at Sarahan is expected to extend its strike length to the south, where mapping
has shown the vein to increase in width, and where recent outcrop samples
returned 5.54 g/t Au & 251 g/t Ag,
and 5.19 g/t Au & 171 g/t Ag.

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
