Legend Mining Limited (Legend) is pleased

to announce assay results from diamond

drillholes (RKDD027 and RKDD029) and a

summary of geological observations from

recently completed diamond drillholes at

the Mawson prospect at the Rockford

Project, Fraser Range, WA.

Legend Managing Director Mr Mark Wilson

said: "The prospectivity at Mawson has

been enhanced by the material widths and

grades of the massive nickel copper

sulphide in hole 27 along with the presence

of platinum and palladium numbers.

"The mineralisation observed in hole 32 is

continuing to develop our knowledge of the

nature of the remobilised nickel copper

sulphide in the vicinity of this hole.

"The overarching point is the amount of

nickel copper sulphide mineralisation we

continue to see at Mawson speaks to a

large system driving the mineralisation

event at this prospect."

TECHNICAL DISCUSSION

RKDD027 - Assay Results

Assay results have been received from diamond drillhole RKDD027 at Mawson (see Figure 1, Figure 2, Table 1, and Appendix 1). RKDD027 is part of an infill diamond drill programme designed to extend/close off known Ni-Cu mineralisation at the Mawson massive Ni-Cu sulphide discovery. The drillhole targeted the extension of known mineralisation in RKDD017 and was planned for a 20m separation from RKDD017. RKDD027 remained straighter than planned during drilling, resulting in an actual separation of 23.8m at 230m downhole.

RKDD027 intersected 26.25m of Ni-Cu sulphide including multiple zones of massive, semi-massive and matrix sulphide. Assay results confirm the visual interpretation of good grade primary Ni-Cu sulphide mineralisation at shallow depths below surface. Elevated palladium and platinum encountered in RKDD027 also adds to the prospectivity of Mawson. The amount of mineralisation encountered by drilling continues to speak to a large system driving the mineralisation event at Mawson.

RKDD029 - Assay Results

RKDD029 was drilled up-dip of Ni-Cu mineralisation intersected in RKDD013, RKDD017, and RKDD027 (see Figure 2). RKDD029 intersected 2m of massive Ni-Cu sulphide grading 2.75% Ni, 1.63% Cu, and 0.15% Co from 171.2m. The narrow nature of the sulphide interval in addition with geological logging and DHTEM suggest the Ni-Cu mineralisation is closed off up-dip to the west on this section. RKDD028 was drilled down dip of the Ni-Cu mineralisation (see Figure 2) did not

intersect any significant Ni-Cu mineralisation, with geological logging and DHTEM suggesting the Ni-Cu mineralisation is closed off down-dip immediately to the east on this section.

Current Diamond Drilling Summary (RKDD028 - RKDD032)

RKDD032 was drilled to test a very strong offhole 25,000-70,000S DHTEM conductor identified in RKDD025, interpreted to be the extension of massive sulphide below RKDD025 and RKDD023 (see Figure 1 and Figure 3). This conductor fits the current emplacement model at Mawson for Ni- Cu sulphide mineralisation, being vertical in nature. RKDD032 intersected a remobilised mineralised zone of Ni-Cu sulphide over 30m in thickness downhole, including heavy disseminated, brecciated, semi-massive and massive sulphide, largely hosted in a gabbronorite to olivine gabbronorite intrusive suite (see Table 2 and Appendix 2 for core photos). A total of 10.97m of massive and semi-massive sulphide was intersected across ten zones, within a +27m zone of variable Ni-Cu mineralisation, before crossing a late-stage fault zone. DHTEM is scheduled for RKDD032.
