Empire Managing Director, Sean Richardson commented:
“The commencement of diamond drilling at Yuinmery is an exciting development for the Company. The diamond core will provide crucial lithological and structural data essential in understanding the localisation of mineralisation at Yuinmery.
“This is an important exploration phase at Yuinmery, and we look forward to updating the market as results become available. The results of the drilling are expected to be available during the March quarter of 2022.”

ASX Announcement 15 December 2021

SUMMARY
Empire Resources (ASX:ERL, Empire) is pleased to announce the commencement of diamond core drilling at its Yuinmery Copper-Gold Project in Western Australia.
The 1,800m drilling program is designed to target extensions to mineralisation at Smiths Well, YT01 and Constantine prospects where highly encouraging copper-gold, copper-nickel-cobalt and platinum group metals were encountered in recent deep RC drilling in July 2021[[1]] .
The 2,244m of reverse circulation (RC) drilling completed in July 2021 further delineated the lateral extent and establish continuity of mineralisation at the YT01 Cu-Au-PGM prospect, Smith’s Well Cu-Ni-Co and Constantine PGM prospects.
Smith’s Well intercepts included 16m @ 0.51% Cu, 0.16% Ni & 0.031% Co from 255m in drillhole YRC21-28, including 1m @ 1.05% Cu, 0.19% Ni & 0.033% Co from 261m and 5m @ 0.65% Cu, 0.13% Ni & 0.039% Co from 110m in drillhole YRC21-26 including 1m @ 1.90% Cu, 0.18% Ni & 0.038% Co from 112m.
The results reported above from Smith’s Well are from the deepest mineralised intercepts drilled to date, supporting the hypothesis that Smith’s Well may host economic mineralisation at depth. The mineralised intercepts obtained at Smiths Well since 2019 have very high sulphide content (>50%), primarily Pyrrhotite, enhancing the concept of a substantial mineralised system at depth.
Encouraging PGM results were also returned from drilling at Constantine Prospect, comprising 12m @ 0.41g/t Pd & 0.05g/t Pt from 120m (EOH) in drillhole YRC21-21 including 4m @ 0.64g/t Pd & 0.06g/t Pt from 124m. The drilling at Constantine ended in mineralisation, indicating the mineralised system extends below current drilling depths.

BACKGROUND
Empire’s Yuinmery Project is located 475km northeast of Perth and comprises six contiguous granted mineral tenements covering approximately 106.7km[2] within the Archaean Youanmi Greenstone Belt (“YGB”).
The Yuinmery Project is bounded by the Youanmi shear zone to the west and the Yuinmery shear zone to the east[[2]] (Figure 2). Known copper-gold mineralisation at Yuinmery is of volcanogenic massive sulphide (VMS) style. Empire’s Just Desserts deposit has a previously reported JORC Resource of 2.5Mt @ 1.31% Cu and 0.49g/t Au[[3]] .

Empire has identified a pipeline of Cu, Au, Ni, and PGM targets within its southern Yuinmery tenement area. Multiple targets from greenfields-style conceptual anomalies through to more advanced prospects have been tested by the Company in recent years, culminating the need for diamond drilling techniques to assess deep mineralised targets.

DIAMOND DRILLING
A 1,800m diamond drilling campaign testing several high priority geochemical and geophysical targets prospective for VMS-type Cu-Au and Cu-Ni-PGM mineralisation has commenced at YT01, Constantine, and Smith’s Well.
The program consists of 5 diamond holes to a maximum depth of 450m designed to trace the established mineralisation of those prospects to greater depth.
Diamond drilling allows the lithology to be assessed across the full stratigraphic host sequence, offering valuable structural and geological information important for understanding the relationship between vein hosted and disseminated copper mineralisation. The opportunity to undertake down-hole electromagnetic (DHEM) geophysical surveys in the search for conductors is still present with diamond drilling.
The diamond drilling campaign will run for approximately 4 to 5 weeks until the end of January 2022. Logging, processing and sampling of core will continue throughout the campaign, it is anticipated that final laboratory assays will be returned during the March 2022 quarter.

Smith’s Well – Copper-Nickel-Cobalt Potential
In May 2020 Empire identified a steeply plunging structure trending in a northeast direction at Smith’s Well. This structure has been tested by RC drilling for over 200m of strike and to 240m vertical depth. The structure is associated with the regional magnetic trend and remains open to the northeast and down dip. There is high probability that the copper-nickel mineralisation will continue beyond the zone already identified.
Drilling to date has returned broad zones of disseminated to matrix sulphide mineralisation, including chalcopyrite, pyrrhotite and pyrite in varying concentrations. Drill intercepts of >1% Cu, and associated nickel (>0.2% Ni), gold and cobalt values demonstrate the potential of the prospect[[5]] .
Three RC holes drilled in July 2021[[1]] also intersected a steeply dipping, broad zone of Cu-NiCo mineralisation on the contact between ultramafic rocks and overlying dolerite. Where seen, this contact can be both sharp and irregular, however the mineralisation occurs as matrix and disseminated sulphides within the ultramafic rocks.
The July 2021 RC drilling encountered mineralisation increasing in thickness at depth (Figure 4) in what is interpreted to be a shallowing structure and lithological boundary. Empire believes it may be drilling on the edge of a more laterally extensive sulphide pile. Alternatively the increased thickness seen in the mineralisation could possibly be related to a switch from an extensional regime to a compression regime, post the main mineralisation event at Yuinmery resulting in the remobilisation of mineralisation to its current position.

Constantine Prospect – Ni-PGM Potential
In July 2021[[1]] five RC holes for 692m were drilled at the Constantine Prospect to investigate anomalous Ni and PGM values obtained from shallow RAB drilling in 2010/2011. Analysis of Cu/Pd ratios from historical samples collected from below the base of oxidation had indicated the PGM values are indicative of mineralisation rather than normal mantle concentrations.
Hole YRC21-20 (Figure 6) terminated in mineralisation after having assayed 56m @ 0.10% Ni & 0.01% Co from 52m downhole, an intercept that partially overlaps a deeper interval of 28m @ 0.14% Pd from 104m to end of the hole. Similarly, YRC21-21 ended in mineralisation with an intercept of 12m @ 0.41% Pd from 120m.
Hole YRC21-21 is to planned to be extended by up to 150m of diamond NQ core to test the stratigraphic sequences and assess mineralisation potential at depth.

YT01 Prospect – PGM Discovery
The YT01 prospect was identified by the Company in late 2019 and is associated with a strong east west trending, multi-element (Au-Cu-Zn-Ni) geochemical anomaly that extends over 3.5km in strike length. In June 2020, RC drilling intercepted a broad zone of Cu-Ni-PGM mineralisation. YRC20-28 returned 20m @ 0.39% Cu, 0.11% Ni, 0.02% Co, 0.21g/t Pd & 0.07g/t Pt from 143m[[6]] , including 12m @ 0.38% Cu, 0.34g/t Pd & 0.11g/t Pt from 151m.
In July 2021[[1]] , one 250m RC hole (YRC21-16, Figure 8) was drilled under YRC20-28 to test for continuity of mineralisation at depth. In the targeted downdip position, this hole intersected 36m of mineralisation assaying 0.34% Cu, 0.07% Ni, 0.16% Pd, 0.03% Pt and 0.07g/t Au . These encouraging results demand follow-up and a single deep diamond core hole has been planned for this campaign.

The geology of the YT01 Prospect is poorly understood. The mineralisation occurs as disseminations towards the base of a complex sequence of sheared and altered mafic to intermediate volcanic rocks, which have locally been intruded by thin dolerite units. This maficintermediate volcanic sequence is underlain by talc-rich rocks which may well be ultramafic.
There is an observed zonation to the mineralisation with gold-copper predominating above about 120m vertical depth below which the mineral assemblage also includes nickel, palladium and platinum as well as copper and gold.
