The Diucon mineralised intrusion has been intersected over a strike of approximately 560m, depth of 900m and a true thickness of approximately 300m. Recent drilling has demonstrated that mineralisation extends down plunge for at least 400m to the WSW of the

Mineralisation intersected in HEDD136 remains open in all directions, including up-dip, and to the west toward
Higher grade mineralisation at Diucon in shallow and deeper drilling appears to be associated with inflections on major shear zones.
Further exploration drilling, recommencing this quarter, will focus on identifying these inflections near surface within open pit depths.
Deeper drilling at Diucon has been conducted at a wide spacing on 160m lines and 80m collars along strike of mineralisation previously intersected in HEDD128.
HEDD128 intersected 359.4m @ 1.2g/t Au through the width of the intrusion from 530m down hole comprising intervals calculated at a 0.3g/t Au cut-off grade.
Strong mineralisation at Diucon has now been intersected for approximately 560 metres along strike, to a depth of approximately 900 vertical metres and remains open. Mineralisation on some sections attains a width of 300 metres over multiple lodes.
Extensional Drilling
Deep mineralisation has been intersected in HEDD135 and HEDD136 up to 120 metres west of the
Infill Drilling
Infill drilling at Diucon to upgrade portions of the current mineral resource from Inferred to Indicated to increase ore reserves for the Hemi definitive feasibility study (DFS) continues to support the resource model.
Planned drilling on the southern margin of Diucon and at the base of the PFS pit shell optimisation has the potential to both expand the mineral resource and extend the open pit shell optimisation to the south and at depth. In addition to the southern and down plunge extensions outlined above, work will also be carried out to follow up shallow lodes between Diucon and Eagle, all of which have the potential to add to the Diucon mineral resource
