Results from the first two cored drill holes of a five hole program at Melba Flats near Zeehan have been received. Both holes intersected narrow zones of massive sulphide carrying very high grade nickel and copper with associated platinum, palladium and gold. The best of which, MF23, gave 1.3 metres, 6.1% Nickel, 2% Cu plus Gold and PGMs.

DISCUSSION
MF 22 and MF 23 were both drilled at the Nickel Reward prospect to test for southern and up-dip (shallower) extensions of high grade massive sulphide mineralisation intersected in previous drill holes.
Drill hole MF 22 intersected a narrow zone of high grade massive sulphide within a gabbro dyke host rock 20 metres south-west along strike of previously reported drill hole MF 19 which intersected 5.8 metres 4.6% Ni, 1.8% Cu. The MF 22 intersection is only 30 metres beneath surface and is interpreted as an intersection through the very top of the Nickel Reward massive sulphide body.
Drill hole MF 23 intersected three gabbro hosted high grade massive sulphide bodies within a 12 metre wide interval of mixed gabbro and brecciated sediments. These intersections lie approximately 20 metres south-west along strike of previously reported drill hole MF 11 and 20 metres up-dip (above) previously reported hole MF 13 which intersected 3.6 metres 4.36% Ni, 2.86% Cu and 1.4 metres 7.2% Ni, 2.1% Cu respectively.
All of the massive sulphide intersections in MF 22 and MF 23 contained significant platinum and palladium in the range 1-2 g/t Pt + Pd.
A preliminary interpretation of the results of these first two holes suggest the Nickel Reward massive sulphide deposit is a steeply dipping pipe like body developed within a structurally deformed section of gabbro dyke host rocks.
Results of the final three holes in this program are anticipated in early June.
COMMENT
Allegiance believes that the various high grade near surface nickel/copper/cobalt plus PGMs and gold represent remobilised mineralisation from depth. The present program at Melba Flats is designed to better understand the structures containing and controlling the near surface manifestation of the mineralisation with the objective of (a) defining economic near surface accumulations and (b) subsequently follow the high grade shoots to the source. Genetic considerations suggest the source may represent a very significant target.
