Airfield Gold Project at Marvel Loch
Kula Gold Ltd applied for ELA77/2621 over the south-central part of the Ghooli Dome near Marvel Loch in the Southern Cross region of Western Australia, which is known as the Airfield Gold Project.
Prior exploration at the Airfield Project was completed by Sons of Gwalia Ltd (“SOG”) in the late 1980’s. The exploration reports at the time showed auger gold in soil anomalies in the Ghooli Dome which had not been followed up.
The Airfield Gold Project in Marvel Loch (under application) covers an area of 120km2 and is located 5km east of the town of Marvel Loch, a major gold mining centre in Western Australia. This locality has a number of current and historical mining operations nearby which provides valuable infrastructure and services for potential future development including the Marvel Loch mine and mill which are in production under the ownership of Minjar Gold.
The Southern Cross Greenstone Belt is a strongly deformed, metamorphosed synformal remnant of a once larger greenstone assemblage.
It has been shaped and attenuated by the emplacement of syn-tectonic granitoids (Gee, 1995). These granitoid domes include the Ghooli, Parker and Rankin Domes (Gee, 1982; Keats, 1991).
On a regional scale, sheared lithological contacts are the primary control on the distribution of gold mineralisation. Most of the belt’s production has been derived from shear-hosted deposits (Marvel Loch, Yilgarn Star and Frasers) and to a lesser extent fold hinge deposits, usually in Banded Iron Formation (Copperhead, Golden Pig and Bounty).
The data has been re-processed by the company’s consulting geophysicist who has identified a number of structures with a series of extensional jogs which are co-incident with the historical auger gold in soil anomalies. The targets have strike lengths of over 2km, and some are open to the north and south.
One of the SOG geochemistry samples returned a value of 311ppb and the location of this sample was physically located in the field (see photo above) during the visit. The regolith in the vicinity of the sample contains a mixture of yellow sand and Tertiary in situ laterite.

Westonia Gold Project
Kula Gold Limited have four new exploration licenses adjacent to the Edna May Gold Mine to create the ‘Westonia Gold Project‘, making it an additional focus for Kula’s Southern Cross exploration programs in 2021.
The licenses cover an area of ~357km² and contain gravity and magnetic targets identified by Kula from reprocessing publicly available data.
This acquisition continues Kula’s focus of drilling near to operating gold mines as geologically proven areas for discovery, and importantly the development and mining of any discovery is potentially much quicker and any development of future projects would require far less capex than a green fields new mine development.
The Edna May gold mine is a substantial producer in the Southern Cross region, owned by Ramelius Resources Ltd (ASX:RMS). It has a notable production history as detailed later in this release, including historical production 1911-1991 of 700,000 Oz, Since re-starting in 2010 has produced approximately 80-100,000 Oz p.a. and hosts resources of 28mt @1.0 g/t gold for 930,000 Oz as at 31 December 2020. (Ramelius Resources Ltd Annual Report 31 December 2020).
In total, the Edna May gold mine has an endowment of over 2 million Oz gold. Read the history of Edna May here.
No historical gold drilling has been undertaken on the southern section (E77/2766), as per the WAMEX database.
Kula plans to test the gravity anomaly shown in Figure 2 below with deeper auger drilling to adequately test for gold anomalism below the interpreted transported soil cover.
The gravity anomaly of interest is similar in tenor to surrounding anomalies which host gold mineralisation (yellow triangles in the figure below) and include the Edna May gold deposits.
The licences, to the northeast of Edna May, were acquired based on magnetic targets which suggest a potential northern extension of the greenstone belt as shown in Figure 3 below.
Previous exploration in Kula’s Northern Westonia license has consisted of surface sampling which did not reveal any significant gold anomalies. Kula’s concept is that the previous surface soil sampling work was ineffective in testing the areas for gold mineralisation, therefore Kula will employ deeper auger type geochemical sampling to better test the gold potential of the licences at low cost.
Further work on the Westonia project is in progress, and results will be reported in due course.
⛏️ The acquisition of the Westonia Gold Project now brings Kula’s projects at Southern Cross to a total of three – alongside Airfield Gold at Marvel Loch and Rankin Dome.
Rankin Dome 1 & 2 Gold Projects
Kula Gold Limited also has a project located 10k west and 26km north west (respectively) of Southern Cross known as the Rankin Dome Gold Project.
Rankin Dome 1’s ELA77/2709 was applied for in July 2020 which covers approx 160km2 and is located 10km west of Southern Cross.
A field trip was completed in September 2020 which successfully located a 1988 water bore drill hole which had been assayed for gold, and identified gold values of 0.46g/t Au over 2m from 10m vertical downhole in amphibolite. 3 historic RC drill holes were located during the field visit which are not in the DMIRS database. The drill cuttings were logged as amphibolite (greenstone possibly meta High Mg Basalt) unit with a soapy feel, although the area is mapped as granite. The amphibolite is over 1km wide which adds significantly to the prospectivity of this project. The amphibolite is not obvious in the open file magnetics which show a granite signature suggesting the amphibolite is overlying the granite in this area.
Landowner agreement has been secured over a significant portion of the licence including the area with amphibolite. On granting of the license, the initial work plan will comprise of a shallow geochemical air-core drilling program over each target area totalling approximately 200 holes.
Rankin Dome 2 (E77/2753) was established in February 2021 after exploration at the end of 2020 discovered Ultramafics with Nickel and Gold potential.
A new licence (E77/2753) was applied for 26km north-west of Southern Cross after a field visit in late 2020 showed Ultramafics outcropping in the north-west corner of the licence application. The magnetic interpretation shows about 6km of potential Ultramafic strike and a further 3.5km of strike in the south-east corner of the licence which require testing.
This licence abuts and extends the company’s existing Rankin Dome 1 Project (E77/2709).
