NEW GOLD DISCOVERY AT HAFLINGER
DRILLING INTERSECTS 52m @ 1.4g/t Au , INCLUDING 12m @ 3.1g/t Au
HIGHLIGHTS
-
Drilling on the Celia shear structure at the Haflinger gold target within the Yandal Gold Project in WA has yielded a significant new discovery:
-
52m @ 1.4g/t Au from 64m, including 12m @ 3.1g/t Au (MPAC262)
-
This hole was drilled south of the two bottom-of-hole results reported earlier this week, both of which ‘clipped’ the targeted mafic-intermediate contact structure:[1]
-
2m @ 3.4g/t Au from 148m to BOH, within a broader 6m @ 1.4g/t Au from 144m (MPAC187) – MPAC262 is 500m south of this hole.
-
4m @ 2.9g/t Au from 148m within a broader 16m @ 1.0g/t Au from 136m (MPAC231) – MPAC262 is 200m south of this hole.
-
The mineralisation occurs in a highly favourable structural setting, where the mafic-intermediate contact flexures to the south-east, creating a region of intense deformation (see Figure 1).
-
These three holes now define the mineralised Haflinger trend over a minimum ~500m, with the geology becoming more favourable as drilling moves southwards towards the structural flexure.
-
Gateway remains well capitalised to undertake planned 2026 exploration, having approximately $13.1m (cash and liquid ASX securities) at the end of the September quarter, as well as having completed an additional $22.5m capital raising post September quarter.
Introduction
Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to advise that it has discovered a significant new zone of gold mineralisation from recent aircore drilling at the Haflinger gold target, within its 100%-owned Yandal Gold Project in Western Australia.
Management Comment
Gateway’s Executive Chairman, Mr Andrew Bray, said: The result in MPAC262 of 52m @ 1.4g/t Au, including 12m @ 3.1g/t Au, is an outstanding new discovery from the aircore drilling. Most importantly, this isn’t an isolated result – it builds substantially on the two BOH results we released earlier in the week, both of which returned high-grade gold within the key mafic-intermediate contact structure.
The 2m @ 3.4g/t Au in MPAC187[1] was intersected in fresh rock in the final two metres of the hole before blade refusal. That result is 500m to the north of today’s result. MPAC231, which sits in between those two holes, also ‘clipped’ the key structure, returning 4m @ 2.9g/t Au from 148m in fresh rock (within a broader zone of 16m @ 1.0g/t Au)[1] . With today’s result, the structure has now been intersected over a strike length spanning ~500m and it remains open to the south.
Excitingly, the geology becomes more favourable as we move southwards. This gold mineralisation is located in a highly promising geological setting where the mafic-intermediate contact flexures to the south-east, creating significant complexity and a favourable location for gold deposition due to enhanced fluid flow and trapping mechanisms at the ‘bend’. The next several lines of aircore drilling will drill closer to (and through) this flexure.
Haflinger is clearly shaping up as a very promising high-grade gold structure. Aircore drilling will commence very shortly with two rigs on site. One rig will have the sole focus of increasing drill density around this trend, while the second rig will continue systematically following the eastern Mustang shear southwards. The Company will then undertake follow-up RC drilling.”

Yandal Gold Project
Drilling along the Celia Shear structure has yielded a new gold discovery at Haflinger:
- MPAC262: 52m @ 1.4g/t Au, including 12m @ 3.1g/t Au from 64m
Mineralisation at Haflinger is located along the contact between mafic and intermediate lithologies within the Celia Shear Zone (see Figure 2). Southward, the sheared contact flexures eastward resulting in a series of dilationary structures that have allowed for localised enhanced fluid flow. Interpretation of magnetic imagery shows that the flexure zone that hosts Haflinger continues southward for a least a further 400m, with the next several lines of drilling planned to intersect this structural zone.

Figure 1: Topographic map highlighting aircore intercepts (Au ppm) received to date, in relation to major shear zones and planned drilling across the Mustang-Pony Trend.
Historical rotary airblast drilling across the Haflinger Prospect largely failed to penetrate transported cover and the zone of depletion, rendering previous exploration efforts ineffective at testing the mineralised structures (see Figure 2).
Along strike 200m to the south of drillhole MPAC0262, major northeast-trending brittle structures intersect the target shear zone. As seen elsewhere across the Yandal Project, the intersection of such NE-structures with a mineralised shear zone results in an increased depth of weathering and enhanced supergene enrichment (i.e. thicker oxide mineralisation).
The Company is expecting this area to have the most impressive mineralisation within the target area.

Aircore drilling by Gateway has been far more effective at penetrating into fresh rock and has successfully defined primary mineralisation, hosted within the mafic-intermediate contact, over a minimum strike length of 500m. Aircore drilling results at Haflinger announced previously by the Company highlight the underlying sheared contact as a high-grade target:[2]
-
MPAC187: 2m @ 3.4g/t Au from 148m to BOH, within a broader 6m @ 1.4g/t Au from 144m
-
MPAC231: 4m @ 2.9g/t Au from 148m within a broader 16m @ 1.0g/t Au from 136m
MPAC262 is located 500m south of MPAC187 and 200m south of MPAC231, showing consistent ~3.0g/t mineralisation over a minimum strike of 500m.
Drill results are pending for completed aircore hole MPAC263. This hole was drilled stepping back from MPAC262 and ended within the highly-sheared target structure. Assay results, once received, will be released to the market in due course.

Upcoming Drilling
Aircore drilling will recommence in the coming days with two rigs on site. The first rig will solely focus on infill drilling along the Haflinger trend. The increased drill density is expected to accurately delineate the key mafic-intermediate contact shear zone. These targets will then be followed up by RC drilling.
The second rig will drill systematically southwards along the Mustang Shear, with the aim of approximately mapping the mafic-intermediate contact. Follow-up, closer spaced aircore is expected to then accurately define the key contact zone in preparation for subsequent RC drilling.
