ASX Announcement DRILLING RESULTS GIDGEE PROJECT, WA

At Gidgee latest drilling confirms Rosie North gold mineralised zone extends over 250 metres and is open along strike and at depth

Gateway Mining NL (ASX: GML) announces new reverse circulation (RC) drilling results from its Gidgee Project in Western Australia.

Drilling has confirmed gold mineralisation in the oxide zone and discovered $\overline{a}$ blind narrow high-grade gold veins (up to 24 g/t gold) in the footwall basalts below the main mineralised gold trend to a depth of 80 metres downhole.

Gold intersections include:	2 metres $@$ 12.8 g/t	3 metres $@6.0$ g/t
	2 metres $@$ 9.8 g/t	5 metres $@$ 6.5 g/t
	16 metres $@$ 1.9 g/t	5 metres $@3.9$ g/t

• Recent successful RAB drilling at S Bend, to the north of Rosie means future drilling will now focus on a total strike length of over 600 metres.
• Barrelmaker Nickel petrological studies on drill chip samples confirm the rock sequence targeted by Gateway to be of komatiitic affinity and exhibits positive attributes for nickel-sulphide exploration

Airport Gateway 85%. Herald Resources Limited 15%

Airport is an extensive 4 kilometre long gold anomalous trend containing numerous zones of high-grade quartz veins discovered by Gateway drilling.

Sixteen RC holes for 975 metres were drilled at the Rosie North prospect. A total of eight drill traverses were completed testing a strike length of approximately 250 metres.

Holes were drilled to test gold mineralisation encountered in previous shallow rotary airblast (RAB) drilling within the oxide zone with some testing below this for gold mineralisation at depth.

Rosie North is located on the contact zone between the Montague granodiorite to the east and basaltic rocks to the west. Gold mineralisation is closely associated to the shallow easterly dipping contact within the oxide zone as evident from drilling and the mined Rosie Castle open pit to the south.

New drilling has successfully intersected gold mineralisation along the contact zone over a 250 metre strike length that is open to the north. Drilling has also intersected narrow steeply dipping high-grade quartz-pyrite gold veins on the footwall side (below) of the main Rosie trend. Significantly the vein mineralisation appears continuous down dip in the fresh rock zone and has returned grades of up to 24 g/t gold. The zone has been intersected over a strike length of 75 metres and is open to the south and down dip.

Drilling is still at a 50 metre spacing over the northern 150 metres. Significantly the most northern hole returned 16 metres @ 1.96 g/t gold and is open along strike and at depth.

Recent RAB drilling results reported (Dec 2003 Quarterly) from the S Bend prospect located to the north of Rosie North has enhanced the potential of the area. Results have confirmed a gold anomalous trend over 150 metres strike length. Gold mineralisation is closely related to the granodiorite basalt contact zone.

RAB drilling composite sample results have included 5 metres @ 13.15 g/t gold from 30-35 metres downhole, 5 metres $@$ 6.86 g/t gold from 18 metres depth and 10 metres $@$ 10.5 g/t gold.

The recent discovery of blind high-grade gold veins in the footwall basalts and recent gold grades returned from RAB drilling at S Bend is encouraging. Future drilling will focus on a total strike length over 600 metres from S Bend to Rosie North. Infill drilling is required to further test the oxide zone and to test for hidden high-grade veins in the hanging wall basalts.

Recent drilling confirms the potential for the Rosie North and S Bend prospects to link at depth.

Legendre Gateway earning 80%.

Three holes for 378 metres were drilled to test beneath gold in laterite and supergene gold anomalism in previous RAB drilling. Holes were drilled 50 metres apart on three sections.

Primary gold mineralisation was discovered in narrow guartz veining below the surface and saprolite anomalism. Results included 5 metres $@$ 1.9 g/t gold and 1 m $@$ 1.37 g/t gold. The extent of the quartz veins is at this stage unknown and will require further testing.

Barrelmaker Nickel Gateway earning 80%. Gateway100%

Barrelmaker is located on the western side of the Gum Creek Greenstone Belt 15 kilometres west of Airport. Previous RAB drilling by Gateway exploring for gold mineralisation has delineated ultramafics over a 3.5 kilometre length hidden below transported lateritised cover. The shallow drilling discovered elevated nickel (>0.3%), copper (>900ppm) and platinum (up to 47ppb). An interpretation of airborne magnetics confirms a magnetic high coincident with the ultramafic zone as delineated in the drilling. The zone is open to the south.

As confirmed in the December 2003 quarterly report, the company whilst investigating the area for its potential to host nickel sulphides, attempted to drill three RC holes targeted to reach 200-240 metres depth. All holes failed to reach target depths due to ground conditions and water flow. Nevertheless holes successfully intersected ultramafic host rocks. The abandoned holes reported nickel up to 5558ppm and copper up to 535ppm.

Hole GRC099 intersected a three metre wide ironstone zone within oxidised ultramafic at a depth of 64 metres. This may reflect a massive sulphide horizon at depth and will be further investigated.

Results of petrological studies on samples from the drill holes indicate the rock sequence targeted by Gateway has positive attributes to host nickel-sulphide mineralisation. The rocks are of komatiitic affinity formed as extrusive lava flows.

A ground EM survey will be completed next quarter to generate nickel sulphide targets along what is now confirmed as a prospective komatiitic sequence that has never been prospected for nickel sulphide mineralisation.
