JUST DESSERTS – JORC 2012 RESOURCE
In 2016 the Company delineated a JORC 2012 compliant Resource for the Just Desserts deposit of 2.52Mt@ 1.31% Cu & 0.49g/t Au, including 1.27Mt @ 1.31% Cu & 0.64g/t Au in Indicated classification (refer ASX:ERL “Updated copper-gold Resource Yuinmery Project” 17 May 2016).
The Just Desserts deposit consists of a medium to steeply easterly dipping North-West striking massive and disseminated sulphide zone which is anomalous in copper and gold. The mineralisation occurs over a strike length of 760m, a vertical depth of 400m and a true width between 2m and 25m. The mineralisation is offset in places. The deposit remains open at depth.

A ZONE – HIGH GRADE COPPER OPPORTUNITY
The A-Zone prospect is located 1.3km along strike from the existing Just Desserts Resource of 2.5Mt @ 1.31% Cu & 0.49g/t Au. Previous drilling has returned high-grade results, including 12m @ 2.05% Cu from 138m (YRC18-01) and 7m @ 3.3% Cu from 192m (YRC11-26). Limited exploration has been undertaken at A Zone since 2011. With mineralisation open in all directions A Zone offers an opportunity to expand the scale potential of the Project.

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, including 12m @ 0.34g/t Pd & 0.11g/t Pt from 151m.

SMITH’S WELL – COPPER-NICKEL POTENTIAL
In May 2020 Empire identified a steeply plunging structure trending in a North-East direction at Smiths 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 North-East and down dip. There is every likelihood the copper-nickel mineralisation has continuity well 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. Copper Drill intercepts of >1% Cu and associated elevated nickel (>0.2% Ni), low-level gold and cobalt values demonstrate the potential of the prospect.
