HIGH GRADE DRILLING RESULTS CONFIRM
PROSPERO POTENTIAL
Jubilee Mines NL (ASX: JBM) is pleased to announce that the latest drilling at the Prospero Deposit,
located 4.5 kilometres south of the Cosmos Mine (figure 1), has confirmed the internal continuity and
high grade of the nickel sulphide mineralisation and further extended the mineralisation up-dip.
Results from this drilling are summarised below (see table 1 for details):
• BJD082e 2.26 metres @ 8.52% Ni
• BJD082f 14.0 metres @ 6.56% Ni
• BJD112c 4.0 metres @ 10.67% Ni
BJD82f and BJD112c were drilled internal to the mineralised zone (figure 2) and although still wide
spaced, have confirmed the internal continuity of the mineralisation.
BJD82e was drilled approximately 25 metres up dip from previous drilling (figure 2) and indicates that
the high grade nickel mineralisation remains open in this direction.
The mineralisation at Prospero typically consists of massive, massive-breccia and massive-stringer
high tenor, nickel sulphides associated with a package of felsic volcanic rocks internal to the
ultramafic sequence.
Based on current information the intersections are considered to be close to true width.
