Empire Managing Director, Sean Richardson commented:
“ RC drilling at Yuinmery continues to return excellent results. The results from drilling reaffirms the Company’s view that the Yuinmery Project has strong potential to host multiple copper-gold and copper-nickel deposits.
“The excellent results from drilling at YT01 highlight the potential for discovery of new coppergold deposits within the new southern horizon. Meanwhile, Smith Well continues to demonstrate potential with more broad zones of sulphide mineralisation returned from this prospect. The Company looks forward to further investigation of this exciting prospect.
“The Company’s systematic approach to undertaking exploration activities continues to return positive results.”
YUINMERY PROJECT DRILLING
In March 2020 Empire completed a seven (7) hole reverse circulation (RC) drill program for 780m at the Yuinmery Copper-Gold Project. The program tested for copper-gold sulphide mineralisation at YT01 and followed up encouraging RC results from the January RC drill program at Smith Well[4] .

YT01 Prospect
The 3.5km southern horizon was identified by the Company in late 2019 by compiling and analysing historical geochemical, geological mapping, drilling and geophysics datasets[2] . By the end of 2019, the Company had undertaken maiden aircore reconnaissance drilling in this area of the project, identifying copper-gold anomalism in the regolith[3] . In January 2020, the Company completed its maiden RC drilling program of the YT01 and YT19 prospects with results demonstrating the excellent potential for discovery of new copper-gold mineralisation[4] .
Following receipt of the initial 4m composite samples, the original 1m split samples of selected mineralisation intervals from the January RC drilling were submitted for analysis. Results from the recently received 1m splits include:
-
1m @ 2.56% Cu from 44m and 3m @ 1.31% Cu from 48m within 12m @ 1.02% Cu from 44m (YRC20-03)
-
3m @ 1.01% Cu from 57m and 1m @ 1.03% Cu from 79m (YRC20-02)
RC drilling at YT01 in March followed up encouraging results in the upper oxide / transition zone by testing down dip extensions targeting copper-gold bearing sulphide mineralisation at depth.
Drilling intercepted trace and disseminated chalcopyrite, pyrrhotite and pyrite sulphides in holes YRC20-14, YRC20-15, YRC20-16 and YRC20-17. Initial 4m composite assays sent for multielement analysis have been received with significant results from drilling including:
-
30m @ 0.50% Cu & 0.07g/t Au from 108m to EOH, including 12m @ 0.73% Cu & 0.10g/t
-
Au from 112m (YRC20-14)
-
12m @ 0.37% Cu & 0.14g/t Au from 144m to EOH, including 4m @ 0.61% Cu & 0.37g/t Au from 152m to EOH (YRC20-15)
-
24m @ 0.44% Cu & 0.12g/t Au from 56m including 4m @ 0.82% Cu & 0.09g/t Au from 56m (YRC20-16)

Select original 1m splits samples from the March 2020 drilling have been collected and submitted for analysis.
Downhole Electromagnetic (DHEM) geophysical surveys are currently being planned for the June quarter. The DHEM surveys will test for electromagnetic signatures commonly associated with sulphide mineralisation. Any encouraging electromagnetic responses returned from the DHEM surveys will assist the Company in designing future drilling programs targeting sulphide mineralisation.

Smith Well Prospect
The Smith Well prospect is a historic copper-gold prospect with recently identified anomalous nickel in drilling. RC Drilling in January 2020 intercepted a 68m downdip zone of sulphides, including chalcopyrite, pyrrhotite and pyrite in varying concentrations, in hole YRC20-10. Copper intercepts of >1% Cu associated with elevated nickel (>0.2% Ni) and low-level gold values[4] demonstrated the potential of the prospect and merits further assessment.
Two holes were drilled in the March RC program to confirm the dip and orientation of the mineralisation identified in YRC20-10. Both holes intercepted mineralisation as either oxide or sulphide. Significant intercepts for this drilling include 28m @ 0.33% Cu & 0.01% Ni from 60m (YRC20-12) and 12m @ 0.49% Cu, 0.28% Ni & 0.03% Co from 86m, including 4m @ 0.61% Cu, 0.32% Ni & 0.04% Co from 94m (YRC20-13).
==> picture [480 x 434] intentionally omitted <==
Figure 5 – Smith Well Drillhole Locations & Modelled Plates Overlain Mid-Time EM Geophysics
Smith Well is interpreted to lie within a broad stratigraphic horizon extending from Smith Well in the east around to the Just Deserts deposit to the west. This stratigraphic horizon includes multiple existing prospects such as C-Zone and Claudius, where promising historical Cu-Au mineralisation has been identified. Smith Well differs from other prospects at Yuinmery in its elevated nickel content. This is interpreted to be the result of fluids from a mafic intrusion interacting with the original copper-gold mineralisation within the volcanics. Further exploration is required to make a definitive assessment.

ASX Announcement 24 April 2020
==> picture [82 x 47] intentionally omitted <==
Additional 1m split samples from the March 2020 drilling at Smith Well have been collected and submitted for analysis.
Further RC drilling is planned for Smith Well in May 2020 to continue testing the extent and orientation of mineralisation at this exciting prospect. Following the drilling, and subject to results, a program of Downhole Electromagnetic (DHEM) geophysical surveys has been planned for the June quarter. The DHEM surveys will test for off-hole electromagnetic sulphide mineralisation signatures.

| sampling, ground magnetics, IP and EM | |||
| were exploration methods used to target | |||
| their vacuum, percussion and diamond | |||
| drilling programs. | |||
| • | Esso Australia Ltd explored the area | ||
| between 1979 and 1984 using EM, RAB and | |||
| diamond drilling in the search for Golden | |||
| Grove - Scuddles type base metal deposits. | |||
| • | Black Hill Minerals Ltd explored part of the | ||
| area for base metals between 1986 and | |||
| 1991. This involved rock chip sampling and | |||
| limited percussion drilling. | |||
| • | Meekal Pty Ltd commenced an exploration | ||
| program in 1985 by remapping parts of the | |||
| syncline and rock chip sampling. In 1986 | |||
| Meekal introduced Arboyne NL into the | |||
| project who carried out gold exploration by | |||
| drilling reverse circulation holes under old | |||
| gold workings. | |||
| • | Between 1989 and 1991 RGC Exploration | ||
| Pty Ltd explored the area concentrating on | |||
| the potential for gold mineralization. This | |||
| exploration consisted of geological mapping, | |||
| rock chip sampling and some RAB drilling. | |||
| • | In 1992 Meekal Pty Ltd joint ventured the | ||
| project to Giralia Resources NL, who | |||
| brought in CRAE as a partner in1993. CRAE | |||
| completed a ground EM survey and drilled | |||
| three diamond holes in its search for base | |||
| metals. | |||
| • | Gindalbie Gold NL then explored the area | ||
| for gold between 1995 and 2000. This work | |||
| entailed a wide spaced soil sampling | |||
| program but although several anomalous | |||
| zones were identified no drilling was | |||
| undertaken. | |||
| • | Mineral Resources Australia / La Mancha | ||
| explored the northern end of the project area | |||
| between 2002 and 2010 completing; | |||
| extensive soil sampling (Auger), | |||
| reconnaissance (RAB / Aircore) drilling and | |||
| geophysical surveys (VTEM and | |||
| aeromagnetic surveys). |

| programmes have been completed as well | |||

| Geology | • Deposit type, geological setting and | • | The Yuinmery project area covers the |
| style of mineralisation. | eastern portion of the Archaean Youanmi | ||
| greenstone belt with rock types consisting | |||
| largely of altered mafic and ultramafic | |||
| volcanic and intrusive rocks with chloritic | |||
| felsic and intermediate volcanic units. The | |||
| volcanic units contain a number of | |||
| intercalated strongly sulphidic cherty | |||
| sediments which are host to VMS copper- | |||
| gold mineralization. In the project area these | |||
| rocks lie on the eastern side of the regional | |||
| Youanmi Fault and form the southern | |||
| closure of a northerly plunging syncline. | |||
| The volcanic rocks have been intruded by | |||
| dolerites, gabbros, pyroxenites and other | |||
| ultramafic rocks which probably form part of | |||
| the layered Youanmi Gabbro Complex. | |||
| Several zones of copper - gold | |||
| mineralization have been identified within | |||
| the project area by previous surface | |||
| sampling and drilling. The volcanogenic | |||
| massive sulphide style mineralization is | |||
| associated with cherts, felsic volcanic | |||
| breccias and tuffs. | |||
| • | Gold mineralisation is interpreted to be | ||
| associated with lower order shears | |||
| subsidiary to either the Youanmi or | |||
| Yuinmery Shear zones. Gold sits in sub- | |||
| vertical shears, and forms narrow, steep | |||
| plunging high grade shoots at minor flexures | |||
| inthe shears as quartz-sulphidelodes. | |||
