Empire Metals Limited, the AIM-quoted resource exploration and development company, is pleased to announce the results of the third phase of reverse circulation (‘RC’) and infill diamond drilling at the Eclipse Gold Project, located 55km north-east of Kalgoorlie, Western Australia (‘Eclipse’ or the ‘Project’).
· Third phase of RC drilling at the Eclipse Gold Project has delivered encouraging results and supports the scaling of the Project’s mineralised footprint.
· The drilling campaign was conducted over a 10 day period from 20 April 2021 to 29 April 2021 during which time 19 RC holes were drilled for a total of 1,893 metres, and three PQ core diameter drill holes were drilled for a total of 201.1 metres.
· The RC drilling has confirmed the existence of several parallel veins in addition to the main Eclipse vein and the diamond drilling has replicated intercepts from previous RC drilling as well as providing an invaluable insight into the nature of the mineralisation and the alteration zones.
· Targeted RC drilling with respect to a twin set of historical workings located SW of Eclipse has proved favourable and has identified a mineralised lode running sub-parallel to the Eclipse vein, referred to as ‘Twin Shafts’.
· The drilling has confirmed the different stockwork style of near-surface mineralisation in the vicinity of the Jack’s Dream old workings, which is breccia in style and has a different orientation to Eclipse/Twin Shafts. This indicates both increased complexity and possibly an increased duration of the gold system.
· Significant RC drilling intercepts include:
o 5m @ 3.54 g/t Au from 126m downhole at Jack’s Dream
o 6m @ 2.39 g/t Au from 50m downhole at Jack’s Dream
o 4m @ 4.78 g/t Au from 66m downhole at Twin Shaft
o 2m @ 3.65 g/t Au from 53m downhole at Eclipse
o 1m @ 4.08 g/t Au from surface at Eclipse
The RC drill intercepts above 1.3 g/t Au from the current phase of drilling are summarised in Table 4 below.
· The consequence of the extensional RC and infill diamond drill campaigns is that the gold camp at Eclipse is starting to present characteristics that underscore the exploration potential.
Shaun Bunn, Managing Director, said: “The results from the most recent drilling campaign at Eclipse are most encouraging, confirming the presence of additional mineralised zones. A new lode, referred to as the Twin Shafts, has also been identified. The lodes at Eclipse and Twin Shafts are sub-parallel veins spanning a lateral distance of 120m. The mineralisation at Jack’s Dream has now been intercepted at depth, 126m downhole, and continues to remain open at depth and to the south-east, towards the Eclipse orebody. The exploration work to date continues to bear fruit and the footprint of mineralisation at Eclipse is starting to gain scale. Work at Eclipse will continue to evaluate and extend the mineralisation at Twin Shafts and Jack’s Dream, and we are also now looking forwards to the first results for our initial soils programme at Central Menzies. ”
The Eclipse Gold Project
Empire Metals has a 75% interest in the high-grade Eclipse Gold Project comprising a mining licence located 55km north-east of Kalgoorlie, Western Australia, together with an option to acquire the remaining 25%.
The project lies within the highly concentrated gold mining region of Western Australia, north-west of famous gold operations such as Kanowna Belle and Paddington (Figure 1).
RC and Diamond drill programmes at Eclipse
The primary purpose of the Eclipse RC drill programme of April 2021 was to test if the mineralised system continues along strike towards Jack’s Dream and to establish how the mineralisation exposed by shafts proximal to Eclipse link with the Eclipse gold system. Infill drilling also added confidence to the mineralisation model and the previous RC drilling around the Eclipse shaft were supported by the addition of three diamond drill holes. The diamond drill holes targeted the Eclipse mineralisation at various depths from surface. They had a dual purpose of both characterising the vein-system hosting the gold mineralisation and to also enable geotechnical assessments ahead of mine design.
BM Geological Services was commissioned by Empire Metals to assist with the supervision of drilling of the drill campaign at the Eclipse Gold Project. iDrilling was engaged for 10 days from Tuesday 20 April 2021 to Thursday 29 April 2021 and drilled a total of 19 RC holes for 1,893 metres. During this period Terra Drilling commenced a programme of three PQ core diameter drill holes for a total of 201.1 metres.
Results for the RC drill programme at Eclipse
The RC drilling resulted in several significant intercepts (Table 1). Due to an inundation of samples at the assay laboratories, it has taken 7-8 weeks for gold assays to be reported. This update presents the results of 1m resplits where available. However in some instances only 4 metre composites samples can be reported.
The mineralisation of Jack’s Dream workings was targeted by a few RC holes. Previously ECRC21_020 encountered significant quartz-breccia hosted gold mineralisation. Recent drill holes ECRC21_045 and ECRC21_046 confirmed that the down dip extent of the primary vein set exceeds 60 metres and has a horizontal strike of 40 metres (Figures 2 and 3).
ECRC21_054 targeted an un-named shaft situated approximately 120 metres south-west of Eclipse and reported 4 metres @ 4.78 g/t Au (Figure 4). It aligns with the locations of a twin set of shafts and represents a new lode, highlighting the potential for multiple subparallel gold-bearing quartz vein arrays within this gold camp. ECRC21_055 also intersected the Twin Shaft mineralisation with 1m @ 1.26 g/t Au.
ECRC21_053 extended the defined Eclipse mineralisation another 30 metres to the north-west. This drill intercept demonstrates that along the Eclipse corridor, the mineralised vein sets will pinch-out but then swell again yielding strong gold mineralisation.
ECRC21_059; ECRC21_060 & ECRC21_062 targeted the Eclipse workings, improving confidence within an area at the southern margin of the Eclipse mineralisation that has strongly relied upon the results of historical drilling.

Results for the diamond drill programme at Eclipse
Each of the three diamond drill holes intersected mineralisation with gold metal concentrations that matched expectations (Table 2). Gold was not present in the larger bucky-white veins but rather it was associated with thin ladder veins proximal to patchy sericite and albite alteration that also comprised disseminated pyrite ± arsenopyrite (Figure 5).
The host rock was largely homogenous and non-descript. However, occasional bands of fine-grained siltstone indicated that the lithology is dominantly a sandstone with minor siltstone occurrences. Mixed sand/silt provenance may have led to the intermediate composition of this material.
The Central Menzies Gold Project
The Company recently announced the signing of an Option Agreement to acquire a 75% interest in the Central Menzies Gold Project, located in the Menzies Shire, approximately 115km north of the city of Kalgoorlie-Boulder and 10km south of the township of Menzies (Figure 1). The prospect is accessible from Kalgoorlie-Boulder via the sealed Goldfields Highway and then by a 2km unsealed road.
Central Menzies is wholly located within a north-north-west trending greenstone belt, with basalts as the dominant hosts together with interbedded shales and magnetite-rich banded iron formations (“BIF”), with mineralisation hosted within the Menzies Shear Zone, or associated fault splays. Gold-bearing quartz veins occur along the contact between basalts and sediments. A series of structurally controlled high-grade gold deposits have been historically mined and display extensive exploration potential for high-grade extensions.
The Company continues to build up a comprehensive geological database for Central Menzies utilising historical exploration reports and data. The Company is currently conducting soil sampling for geochemical mapping ahead of a planned RC drilling campaign expected to commence in August.
