FURTHER WIDE, HIGH-GRADE GOLD AT HAFLINGER

64m @ 1.2g/t Au INTERSECTED 100m NORTH OF THE DISCOVERY HOLE

HIGHLIGHTS

• Aircore drilling at Haflinger continues to delineate shallow, high-grade gold mineralisation:

• 64m @ 1.2g/t Au from 56m incl 24m @ 2.4g/t Au in MPAC0291

• 20m @ 1.4g/t Au from 64m incl 4m @ 6.0g/t Au in MPAC0264

• 12m @ 1.0g/t Au from 140m in MPAC0263 (hole ended in the shear zone)

• These new results build on the initial discovery holes at Haflinger:[1]

• 52m @ 1.4g/t Au from 64m incl 12m @ 3.1g/t Au in MPAC0262

• 2m @ 3.4g/t Au from 148m to BOH in MPAC0187 (hole ended in the shear zone)

• 4m @ 2.9g/t Au from 148m within 16m @ 1.0g/t Au in MPAC0231 (hole clipped the shear zone)

• Drilling to date has delineated high-grade gold mineralisation over ~500m in strike, with the system remaining open to the south.

• Mineralisation occurs in a highly favourable structural setting, where the primary maficintermediate contact flexures to the southeast, creating a zone of intense deformation.

• Gateway has now completed additional drilling for a further 1.2km south of the current Haflinger footprint – with assays due in Q2 2026.

• Recent drilling has intersected a highly silica-altered mylonitic shear zone.

• Shearing intensity increases towards the south, indicating strong potential for further mineralisation.

• Gateway remains well capitalised to execute its 2026 exploration programs, with $19.4m cash and $9.3m in liquid ASX securities at the end of the December 2025 quarter.

Management Comment

Gateway's Executive Chairman, Mr Andrew Bray, said: “These latest results from Haflinger continue to reinforce what is emerging as a very promising high-grade gold discovery within our Yandal Gold Project. The standout intercept in MPAC0291 – a broad 64m at 1.2g/t Au with a higher-grade core of 24m at 2.4g/t Au – together with the thick oxide zone intersected 100m to the south in MPAC0264 – 20m @ 1.4g/t Au – demonstrate consistent mineralisation in a structurally favourable setting, where the mafic-intermediate contact flexures southeast, enhancing deformation and fluid flow.

Combined with our previous hits, we have now defined this system over at least 500m of strike, and it remains wide open to the south. This is particularly exciting given the increased shearing intensity observed in recent drilling moving southwards along the prospect.

Our methodical approach to exploration continues to unlock the potential of this under-explored region within the broader Yandal Project. Two rigs are systematically testing key target corridors, with multiple new areas of shearing, veining and strong alteration being intersected. In approximately two weeks, both rigs – together with an additional RC rig – will mobilise to our top priority target, Great Western, to commence the first systematic drilling campaign across this highly prospective, at-surface target.”

Introduction

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to provide an update on recent aircore drilling activities at the Haflinger Prospect, located on the Celia Shear Zone, within its 100%owned Yandal Gold Project in Western Australia.

Haflinger Discovery

The Haflinger discovery is situated on the regionally significant Celia Shear Zones in a structurally complex geological setting. Further drilling at the prospect has yielded excellent results, including:

• MPAC0291: 64m @ 1.2g/t Au from 56m, including 24m @ 2.4g/t Au

• MPAC0264: 20m @ 1.4g/t Au from 64m, including 4m @ 6.0g/t Au

• MPAC0263: 12m @ 1.0g/t Au from 140m (hole ended in shear zone)

==> picture [452 x 280] intentionally omitted <==

Figure 1: Cross section highlighting the mineralisation encountered in MPAC291.

These results build on the initial holes released by the Company:[1]

• MPAC0262: 52m @ 1.4g/t Au from 64m incl 12m @ 3.1g/t Au in MPAC0262

• MPAC0187: 2m @ 3.4g/t Au from 148m to BOH in MPAC0187 (hole ended in shear zone)

• MPAC0231: 4m @ 2.9g/t Au from 148m within 16m @ 1.0g/t Au (hole clipped shear zone)

Assays to date have confirmed the presence of high-grade mineralisation over a minimum 500m strike length. The system remains open to the south, where the geology becomes increasingly favourable with greater flexure and structural deformation.

Drilling so far has highlighted the potential for multiple stacked, high-grade internal lodes within the broader shear zone. Drilling on the section line that includes holes MPAC0262-264 indicates an overall target shear zone at this position of ~70m (see Figure 2).

MPAC0291 (released today), located 100m north of the discovery hole MPAC0262, ended in intermediate volcanics, while MPAC0292 (also released today and 50m east of MPAC0291) ended in mafic volcanics, leaving the target shear zone between them largely untested (see Figure 1 above).

Drilling has continued for a further 1.2km south from the current Haflinger mineralised footprint (see Figure 3 above).

This drilling has intersected a highly silica-altered mylonitic shear zone, suggesting that the target structure extends beyond current results with intensified shearing. This is indicative of enhanced prospectivity for dilation and gold deposition.

Assays from this 1.2km extension are expected to be received in Q2 2026.
