heavy reading..... this from page 7:

“In the Ossu area, float and large boulders of pyrite and chalcopyrite are found on
a ridge of serpentinite. The area is 15x15 metres wide and the float is in situ. Grades in
the pyrite are reported to be 10 per cent of copper, 3-4 g/t gold and 70 g/t silver.
Gossanous material was observed encrusting the sulfides…” (Wittouck, 1937). These
spectacular large boulders of copper/gold/silver massive sulfide weighing from 5 to 15
tons are located at the bottom of a serpentine ridge along the track from Ossu to Leca, on
the east side of the Vei Berek stream about 10 metres above the stream level (photo 3.2).
The occurrence has not been evaluated and explored. The Allied Mining
Company (1937) describes the occurrence as “…probably small…” without having done
sufficient work. With today’s knowledge of this style of mineralization, one must
conclude that the outcrop itself is a significant indication and may well be the tip of a
much larger ore body. The confirmed occurrence of these boulders in close association
with the serpentinized basic/ultrabasic rock sequence suggests that the other areas
underlain by these ophiolites have potential for the same mineralization.
