re: Ann: Drilling of Granite Creek Intersects... Drilling of Granite Creek EM anomaly intersects multiple sulphide zones
Oroya Mining Ltd (ASX:ORO) advises that drilling of the second hole from site GC-01 to test
the Granite Creek EM anomaly has intersected 24 metres of sulphide-rich zones so far and was
drilling ahead at 324 metres on 3rd March. Three significant sulphide rich zones have been
intersected:
• 10 metres of disseminated sulphide from 100 metres
• 12.2 metres including 5.8m of massive sulphide (about 50%)from 225 metres
• 4 metres of disseminated sulphide from 299.5 metres
The sulphide rich zones coincide with part of the major conductor predicted by the HeliTEM
results. The mineralisation in the upper two layers is too fine grained to determine copper
content but there is visible fine Chalcopyrite (copper sulphide) from 299.5 metres. The core is
being processed for laboratory assay. True widths are unknown.

GC-01-A is oriented toward 090 (East) with 60 degrees dip and drilling will continue to 400
metres
The sulphide zones are in altered granitic and volcanic rocks, indicating that the prospective
fault contact with sedimentary rocks has not yet been intersected. If so this prospective target is
still to be tested by this or future holes.
The first drill hole from site GC-03-A near the western edge of the anomaly did not intersect
strong mineralisation and was terminated at 250 metres.
