Reverse Circulation Drilling at Mulgabbie North Gold Discovery

OzAurum Resources Ltd ( ASX: OZM or OzAurum or the Company ) is pleased advise that it has commenced Reverse Circulation (RC) at the Cross Fault Gold Discovery within the Mulgabbie North Gold Project.

Highlights

• RC Drilling Program Commenced: A 17 hole, 1,600m RC drilling program started at the Cross Fault Discovery zone within the Mulgabbie North Project.

• Drilling Focus: The program aims to expand high grade gold mineralisation at Cross Fault, both at depth and along strike.

• Key Cross Fault RC Drilling Results: Previous RC drilling yielded significant gold intersections, that will be targeted in this program including:

• 48m @ 1.66 g/t gold (Au) – (from surface to 48m, EOH) including 9m @ 5.79 g/t Au (from 12m) – MNORC 221

• 12m @ 4.26 g/t Au – (from 18m) – including 2m @ 22.58 g/t Au MNORC 220

• 17m @ 1.65 g/t Au – (from 45m) – within 39m @ 1.09 g/t Au (from 31m) MNORC 222

• 10m @ 1.80 g/t Au – (from 127m) – and 1m 3.91 g/t Au to end of hole (EOH) within 35m @ 0.79 g/t Au (from 103m) MNORC 251

CEO and Managing Director, Andrew Pumphrey, commented:

"This RC drilling program will target high grade gold mineralisation at the Cross Fault Project at Mulgabbie North. The learnings from our recently completed diamond drilling have been applied to this latest round of RC drilling.

We are systematically exploring the potential of this discovery, and we look forward to receiving the assay results in due course. We remain committed to advancing the Mulgabbie North project and delivering value to our shareholders.”

Mulgabbie North –RC Drilling Cross Fault Target

The aim of this 17 hole 1,600m drilling programme is testing high grade gold mineralisation recently intersected in RC drilling at the new Mulgabbie North Cross Fault Discovery.

Previously released results (refer to ASX Announcements 1/04/25 and 6/05/25) in areas that are targeted in this drilling campaign include:

• 48m @ 1.66 g/t gold (Au) – (from surface to 48m, EOH) including 9m @ 5.79 g/t Au (from 12m) – MNORC 221

• 12m @ 4.26 g/t Au – (from 18m) – including 2m @ 22.58 g/t Au MNORC 220

• 17m @ 1.65 g/t Au – (from 45m) – within 39m @ 1.09 g/t Au (from 31m) MNORC 222

• 10m @ 1.80 g/t Au – (from 127m) – and 1m 3.91 g/t Au to end of hole (EOH) within 35m @ 0.79 g/t Au (from 103m) MNORC 251

Geological Discussion

The key observation from the recent diamond drilling program (ASX release 30/05/25) is that gold mineralisation at the western part of Cross Fault (at MNODH 017) is a sheeted vein system and mineralisation at the eastern contact (in MNODH 018) is breccia dominated. In both drill holes, faults are associated with higher-grade gold mineralisation. The intermediate volcanoclastic host lithology at Cross Fault is dominated by conglomerate, with interbedded sandstone units.

The results of the recent diamond drilling has informed OZM’s current RC drilling at Cross Fault. OZM considers that this information can be applied along the entire Relief Shear. OZM is still working on the geological interpretation of this area and will continue to seek opinions from structural geology consultant, Dr Brett Davis.

OZM continues to undertake geological fieldwork along the Relief Shear and the nearby Golden Goose prospect, seeking to locate north-south striking faults in outcrop. Such faults are associated with gold mineralisation at nearby Carosue Dam and other significant gold deposits in the Eastern Goldfields.

Sandstone appears to be the dominant host to gold mineralisation, with extensive quartz veining. Sandstones represent a brittle host rock and such mineralisation is being mined in the Carosue Dam basin, with pits approximately 2km from Mulgabbie North.

The Mulgabbie North project areas, including James, Ben and Alicia, are hosted by extensively foliated conglomerate facies, the foliation resulting from ductile deformation. Sandstone units are brittle host rocks.

OZM considers this size-grading to be typical of intermediate volcaniclastic units, where facies can vary from mudstone and sandstone through to conglomerate. The intermediate volcaniclastic, with its variety of facies, extends along the Relief Shear, within OZM tenure, for some 8 km and represents the eastern limb on the Carouse Dam basin syncline. The western limb hosts the Carosue Dam mines, operated by Northern Star Limited (NST, figure 3 – intermediate volcaniclastic coloured on the plan).

OZM laboratory assay turnaround times currently vary from two weeks to six weeks, depending on workload and laboratories in Kalgoorlie are busy as a result of the current gold boom, with mine grade control samples being given priority over exploration samples.
