Magnetic Resources NL (Magnetic or the Company) is pleased to announce an Updated Mineral Resource Estimates from its deposits in the Laverton and Homeward Bound area. The main deposits include Hawks Nest 9 (HN9), Lady Julie Central (LJC), Lady Julie North 4 (LJN4), Mount Jumbo and Homeward Bound South, which are all located in an area with well-endowed regional infrastructure including three processing plants within 35kms.
HIGHLIGHTS
- This update incorporates recent drilling results at Lady Julie North 4 (LJN4) and Lady Julie Central (LJC) since the last resource report in February 2023 (“Expands Mineral Resources estimate ASX release 3 February 2023”).
- Updated combined Mineral Resources estimate for the whole project area of:
- 22.7Mt @ 1.69g/t Au totaling 1.24Moz of gold at 0.5g/t cutoff.
- Increase of 107% of the total ounces over the 3 February 2023 ASX Release.
- Significantly, the contained gold in LJN4 has risen from 204,000oz to 852,000oz Au (a 317% increase).
- LJN4 is now by far the largest resource in the project area – and it remains open at depth; exploration continues for similar deposits along the extensive 12km Chatterbox shear.
- Key deposits are close to each other and form part of one mining field.
- Three processing plants are nearby, within 10km - 35km away providing scope for toll processing. Given the scale of the resource upgrade, consideration is now also being given to a dedicated processing plant.
- Ongoing extension drilling continues and is expected to result in further resource increases.
The update follows extensive infill and down-dip drilling mainly at LJN4 and some at LJC.
The verification and reporting of Mineral Resources on behalf of the Company was completed by its JORC Competent Person, Mr M Edwards of Blue Cap Mining. The Mineral Resources Estimate has been prepared and reported in accordance with the 2012 Edition of the JORC Code.
Total Mineral Resources reported for the Laverton and Homeward Bound South projects is now 22.7Mt @ 1.69g/t Au at 0.5g/t cut-off totaling 1,236,000oz of gold (See Table 1 below). The cutoff grade is considered appropriate for a large-scale open pit operation.
Managing Director George Sakalidis commented:
“The Lady Julie North 4 Resource has been the prime drilling focus as reported in periodic releases to the ASX. It has multiple stacked lodes with a number of thick intersections that have not been closed off at depth. The initial deeper drilling started on the 25 January 2023 and has expanded in subsequent months to a 95-hole RC program for 16,356m. Drilling is continuing, with holes in excess of 400m depth, which is expected to increase the current resource at LJN4 of 13.1Mt at 2.02g/t for 852,000oz at a 0.5g/t cut off (Table 2).
This LJN4 deposit sits within a regional structure called the Chatterbox Shear Zone that extends over a 12km length within the Magnetic tenements. This shear extends southwards of LJN4 and has had initial AC and RC drilling completed and some anomalous intersections that will be followed up with some shallow RC drilling for the purpose of finding further gold deposits.
Drilling in the last 6 months included diamond drill holes for geotechnical evaluation of proposed pits, and for hydrology analysis. Project environmental, heritage and technical background studies are close to completion – optimisation and pit design has commenced on LJC and the expanded LJN4 – the aim is to prepare and submit a Mining Proposal in early 2024. Other strategic opportunities are also being investigated”.
The Table below summarises the updated Total Mineral Resource at a 0.5g/t Au cutoff (Table 1), with Table 2 providing details of the major resources. Details for the smaller resources which have not changed can be found in the 3 February 2023 ASX release.

The key deposits that have been drilled in the last six months are LJC and LJN4, which are shown in Table 2 and are further summarised below:
LJC Resource
The LJC (Indicated and Inferred) Resource of 1.33Mt at 1.68g/t Au for 72,200oz is 350m by 200m in plan (Figure 2). 59% of the resource falls in the Indicated category. There are some thicker intersections including a number of intersections that start from surface (Figure 3 a, b and c). The long section (Figure 4) shows a thickened, near surface zone which gently plunges to the south-east forming two distinct zones.

Overview
Magnetic Resources (ASX:MAU) is an Australian company, developing a portfolio of significant gold projects in the established mining province, Laverton region, in Western Australia.
The company owns a 100-percent interest in the Hawks Nest and Lady Julie projects in Laverton, the Homeward Bound South project in Leonora, and the Benjabbering project in Julimar. The main deposits include Hawks Nest 9 (HN9), Lady Julie Central (LJC), Lady Julie North 4 (LJN4), Mount Jumbo and Homeward Bound South, which are all located in an area with well-endowed regional infrastructure, including three processing plants within 10 to 35 kilometres. These plants are owned by well-known operators including Goldfields Genesis/Dacian; Anglo-Ashanti; and Genesis/Dacian.
The projects’ proximity to these existing processing facilities gives enough options to MAU for toll processing without having to invest millions of dollars in constructing its own processing plant.
Several large deposits such as Wallaby, Sunrise Dam and Jupiter Gold are in this jurisdiction. The company’s projects are adjacent to some of these world-class deposits. The Mt Jumbo and Hawks Nest tenements are only 15 kilometres north of the Wallaby deposit. At both HN9 and Lady Julie, Magnetic Resources had identified multiple thickened stacked lodes near-surface, which have some similarities to Wallaby and Sunrise Dam.
LJN4, a key focus for the Laverton project, hosts thick breccia and silica pyrite zones up to 50 metres thick, which are also prevalent in Anglo Ashanti’s world-class Sunrise Dam deposit, both parallel to near-surface breccia zones and vertical mineralization going downwards into several of their deposits. The Mau breccia zones often carry higher grades and are now being extended by new drilling at depth and further to the east and northeast, potentially growing the LJN4 resource.
In November 2023, the company announced a significant increase in the mineral resource estimates. The deposits in the Laverton and Homeward Bound area have seen a significant 107-percent increase over the last report in February 2023. The updated combined mineral resources estimate for the whole project area stands at 22.7 million tonnes (Mt) @ 1.69 grams per ton (g/t) gold totaling 1.24 million ounces (Moz) of gold at 0.5 g/t cutoff.
LJN4 is now, by far, the largest resource in the project area, as its contained gold rose from 204,000 oz to 852,000 oz, a 317-percent increase. Extension drilling continues and is expected to result in further resource increases.
The significance of LJN4’s gold resource has not gone unnoticed, as research firm Argonaut has called it a ‘sleeping giant,’ noting recent drilling at LJN4 “indicates a significant discovery unfolding in the Laverton region.” If MAU can replicate the recent drilling intercepts, the next resource update at LNJ4 could easily make it a 1-Moz deposit. This will position LJN4 as one of the best undeveloped gold assets in the Laverton region.
