Farm-in Joint Venture Agreement expands Red 5 footprint in close proximity to Darlot Gold Mine
The two projects, Darlot East and Mt Zephyr, provide exciting opportunities for the delineation of additional gold resources as part of the Darlot Mining Hub strategy – further expanding Red 5’s exploration footprint in WA’s world-class Eastern Goldfields to over 1,919km[2]
-
Farm-in Joint Venture Agreement signed with Ardea Resources Ltd (ASX: ARL) for Red 5 to earn up to an 80% interest in the Mt Zephyr and Darlot East Gold Projects, both located in close proximity to the Darlot Gold Mine.
-
The Mt Zephyr Project includes five granted Exploration Licences with several gold and base metal targets, including granitoid-hosted gold mineralisation at the Gale Prospect.
-
The Darlot East Project includes two granted Exploration Licences located immediately adjacent to the east of Red 5’s existing Darlot Project tenements, and hosts previously-unmapped greenstones that have seen almost no historical exploration.
-
Red 5 to spend $1.5M over two years to earn an initial 60% interest, with the option to earn an additional 20% interest by spending a further $800k within three years from commencement, for a total 80% interest in the two projects.
Red 5 Limited (ASX: RED) is pleased to announce that it has executed a Farm-in Joint Venture Agreement with ASXlisted explorer, Ardea Resources Ltd (ASX: ARL), to earn up to an 80% interest in two prospective gold exploration projects located in close proximity to the Darlot Gold Mine in the Eastern Goldfields region of Western Australia.
The Farm-in Joint Venture Agreement supports Red 5’s multi-strand strategy to expand the Darlot Mineral Resource base, which includes regional ‘bolt-on’ acquisitions in addition to comprehensive exploration being undertaken as part of the Darlot Mining Hub Strategy.
The Mt Zephyr Project covers an area of 900km[2 ] and represents an excellent gold discovery opportunity, located within 100km trucking distance from the Darlot Mill. Mt Zephyr hosts several areas of known mineralisation, including the Dunn’s Find Prospect (gold associated with Banded Iron Formation) and the Gale Prospect (gold associated with granodiorite intrusion), which shows early-stage similarities to Red 5’s 4.1Moz King of the Hills (KOTH) gold deposit.
Mineralisation within the Mt Zephyr area is associated with the major gold-fertile Celia Lineament structure, extending over a strike length of ~50km of the Mt Zephyr greenstone belt and the northern end of the Mt Morgan greenstone belt.
The Darlot East Project comprises two Exploration Licences in an under-explored area located 8km to the east of the Darlot Mine. Although predominantly underlain by granite batholiths, there is evidence of greenstone in areas previously mapped as granite. The structurally-significant Celia Lineament passes through the tenements, providing an opportunity for mineralising fluids to pass through to form deposits.

Red 5’s Managing Director, Mark Williams, said:
“Following the recent delivery of the Final Feasibility Study for the development of a bulk mining and processing operation at King of the Hills (KOTH), Red 5’s growth vision is based on the establishment of two separate production hubs at KOTH and Darlot.
“This Joint Venture Farm-in Agreement with Ardea Resources provides an exciting opportunity for the discovery of gold resources within economic haulage distance of the Darlot processing plant, which is currently operating at 1Mtpa throughput.

“Ardea’s grassroots exploration programs have delineated a series of highly-prospective targets, including the highpriority Gale Prospect which shows interesting early-stage analogies to our 4.1Moz KOTH deposit.
“Red 5 now has a combined granted tenement footprint of 1,919 km[2] in Western Australia’s Eastern Goldfields (including 423km[2] under application), giving us a commanding position in this world-class gold district and an exceptionally strong growth pipeline of exploration projects.
“We are looking forward to getting on the ground to commence drilling and exploration programs at both the Mt Zephyr and East Darlot projects.”
Joint Venture Farm-in Agreement
Red 5, through its 100%-owned subsidiary Darlot Mining Company Pty Ltd (Darlot), has executed a Farm-in Joint Venture Agreement (Agreement) with Ardea Exploration Pty Ltd, a wholly-owned subsidiary of Ardea Resources Ltd (ASX: ARL) (collectively ‘Ardea’), over the Mt Zephyr and Darlot East Gold Projects in Western Australia (refer to Figures 1 and 2).
Under the terms of the Agreement, Darlot is required to spend $1.5 million within a 2-year period to earn an initial 60% interest in the tenements, after which Darlot may elect to spend an additional $800,000 to earn an additional 20% interest, for a total 80% earned interest in the tenements. Ardea is free-carried by Darlot up to a ‘Decision to Mine’, after which it may elect to contribute pro-rata or dilute. If Ardea’s diluted interest falls below 10%, it will convert to a 1.5% Net Smelter Royalty (NSR).
The list of tenements included within the Agreement is detailed in Table 1.

Mt Zephyr Project – Gold
The Mt Zephyr group of tenements contains both primary gold and nickel mineralisation and encapsulates more than two-thirds of an underexplored greenstone belt traversed by the regionally-significant Celia Lineament (Figure
-
2). The area east of the Celia Lineament is considered highly-prospective for the following reasons:
-
The world-class Jupiter and Wallaby granitoid-hosted gold deposits, as well as numerous historical gold workings, are located east of the Celia Lineament;
-
It is located along-structure from the Mt Morgans and Lake Roe gold deposits;
4
==> picture [157 x 32] intentionally omitted <==
-
First-pass drilling programs completed in the area have confirmed gold mineralisation at the Gale, Dunn’s North and Dunn’s Line Prospects; and
-
First-pass, wide-spaced (160mx160m) drilling has confirmed the presence of granitoid-hosted gold mineralisation at the Gale Prospect.

Gale Prospect
The Gale Prospect is considered to have the highest potential for the early definition of a gold Mineral Resource, with the previous exploration conducted by Ardea indicating[1, 2] :
-
The presence of granitoid-hosted gold mineralisation which has been intersected by limited drilling from surface;
-
Its location proximal to the Celia Shear Zone, along strike from geologically similar Jupiter and Wallaby gold mines;
-
An exceptional 900m x 300m outcrop-limited soil geochemistry anomaly (>0.1g/t Au, up to 1.49g/t Au);
-
Sericite, pyrite, hematite alteration noted in RC drill chips;
-
Gold, arsenic, copper and barium anomalism in soil geochemistry;
-
First-pass, wide-spaced (160x160m) drilling delivered promising results;
-
The mineralised zone remains open in all directions;
5
==> picture [157 x 32] intentionally omitted <==
-
Numerous targets have been defined;
-
Near 100m intercepts are a rarity from a first-pass exploration program and are interpreted as the distal, outlying halo of a significant gold mineralising system;
-
Strong parallels with Dacian’s Jupiter mine and Gold Fields’ Wallaby mine.
Drilling by Ardea in 2019 successfully defined broad intercepts of strong gold anomalism within a granitoid host (Figure 4). Wide-spaced RC drilling on a 160 x 160-metre pattern, across the sub-cropping part of the prospect included best results of:
-
AMZR0006: 96m @ 0.28g/t Au from 2m, including 22m @ 0.48g/t Au from 10m;
-
AMZR0021: 24m @ 0.24g/t Au from 4m;
-
AMZR0002: 22m @ 0.25g/t Au from 6m, including 4m @ 0.79 g/t Au from 6m; and
-
AMZR0018: 20m @ 0.20 g/t Au from 44m.
Results suggest that late-stage NE-striking structures that crosscut the Gale granitoid are spatially related to the gold mineralisation.

Dunn’s Line Prospect
Dunn’s Line is a line of historical workings situated along banded-iron formation (BIF) outcrops to the east of the Celia Shear Zone. The localised workings are distributed over a distance of 4-5kms of exposed BIF, with the host BIF sequence extending up to 18km undercover through various offsets and breaks. Small-scale mining commenced in 1899, with grades between 5 and 90g/t Au reportedly mined from the Mount Zephyr mine.
Ardea carried out a program of shallow air-core drilling (to blade refusal) along the exposed and covered strike extent of the northern parts of Dunn’s Line. This drilling encountered anomalous mineralisation, indicating that gold is associated with pyritic (and sericitic) porphyry intrusives. The results of this program warrant follow-up drilling.
Darlot East (Yandal Belt and Celia Shear Zone)
The Darlot East Project is situated immediately to the east of Red 5’s Darlot Gold Project tenements. It incorporates the Celia Shear Zone towards the east, as well as the eastern margin of the Yandal Greenstone Belt.
Between the Celia Shear Zone and the Yandal Greenstone Belt, multiple generations of granite plutons are evident, as are fragments of greenstones. Several magnetic lows are evident, some of which are coincident with lineament intersections and greenstone fragments.
Prior to Ardea’s reinterpretation of the Darlot East area, greenstones were assumed to be limited, volumetrically insignificant rafts within granitoids. However, the acquisition, integration and interpretation of geophysical data by Ardea indicated that up to 20% of Ardea’s Darlot East tenements is interpreted to be greenstone. On the western margin of the tenement group, the easternmost extent of the Yandal Greenstone Belt comprises a strongly magnetic feature that is possibly a relatively flat-lying mafic layered intrusion.
While no significant soil anomalism was identified in broad (1km x 1km) spaced soil sampling over the area, it should be noted that the areas of early interest, namely the greenstone fragments between the granite plutons, are almost entirely overlain by transported material, thus potentially inhibiting effective testing. Further work is warranted.
Mt Zephyr Project – Nickel and Base Metals
Nickel Sulphide & VMS targets
The Mt Zephyr Project also includes several nickel and base metal targets in the Mount Zephyr project area that have undergone limited historical exploration, with encouraging results:
-
Jones Area A – outcropping, highly oxidised and silicified manganiferous gossans, anomalous in Ni and Cu, with limited historical drilling. Ardea completed 12 air-core drill-holes with best intercepts of 2m at 0.83% Ni from 2m (hole AMZA0022) and 12m at 0.35% Ni from surface (hole AMZA0023).
-
Zephyr North prospect – bulls-eye aeromagnetic feature. Limited historical drilling with best individual assay results of up to 0.31% Ni, 0.075% Cu, and 0.11% Zn.
-
Two Bills Well prospect – shallow historical drilling anomalous in nickel, along strike of a magnetic high.
-
Mt Zephyr VMS-base metal anomalism is evident over a strike length of ~2km, with the mineralised contact evident in magnetics for up to 6km.

| Exploration | • Acknowledgment and appraisal of exploration by other parties. | • The Gale prospect has been subject to limited historic exploration, |
| done by other | mostly as drilling. | |
| parties | • BHP (late 1980s) identified anomalism at surface and drilled 19 | |
| shallow RAB holes immediately southwest of the currently | ||
| defined mineralisation. These early holes were generally less | ||
| than 20m deep in an area of alluvial cover, and are not | ||
| considered to have effectively tested for mineralisation. | ||
| • Aurora Gold (early 1990s) identified sheared and sericite-biotite | ||
| altered granite that was interpreted to be the source of the soil | ||
| anomalism. RAB drill programs yielded results including MZR4 (0 | ||
| to 18 m at 0.51 g/t Au), MZR19 (0 to 18 m at 0.48 g/t Au), and | ||
| MZR49 (0 to 6 m at 1.26 g/t Au). As per the prevailing ideas of | ||
| the day, Aurora assumed vertically-oriented gold lodes, but | ||
| could not make these hold together. | ||
| • Around 2000, shallow RAB drilling by Regal Resources returned | ||
| anomalous geochemical results including 2 m at 3.12 g/t Au from | ||
| 8 m in MZR020 and 2 m at 1.64 g/t Au from 2 m in MZR024. | ||
| • Newcrest drilled 12 RC drillholes, most to 150 m depth, in two | ||
| lines coinciding with known mineralisation, confirming earlier | ||
| gold results and achieving results such as NGRC004 (0 to 48 m at | ||
| 0.19gt Au)and NGRC011(62 to 64 m at 0.71g/t Au). | ||
| Geology | • Deposit type, geological setting and style of mineralisation. | • Mineralisation at Gale appears to be granitoid hosted orogenic |
| gold. Strong parallels are drawn with Dacian’s Jupiter deposit | ||
| around 50 km to the SE. Granitoid plugs are intruded into the | ||
