Burns 1200m Diamond Drill Hole Update
Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to provide a progress report for the 1200m deep diamond drill hole underway to evaluate the Burns Au-Cu intrusion related mineral system at the Company’s wholly owned Eastern Lefroy Gold Project, located 70km southeast of Kalgoorlie.
- The Burns 1200m deep diamond hole, LEFD006, is on course & currently at 570m down-hole as of 29 July 2022
- LEFD006 has intersected multiple new & unexpected, mineralised diorite-porphyry intervals within altered high-Mg basalt. This includes:
- 400m-440m downhole of potassic-altered multi-phase diorite intrusions with chalcopyrite, pyrite + molybdenite
- These visual results support a broader western lateral extent to the Burns Au-Cu system, which indicates:
- the alteration zone is larger than previously interpreted with the contact of the main porphyry target-zone still yet to come (anticipated at ~650m down hole)
- Samples for the first 400m of diamond drilling have been submitted to the laboratory with preliminary results expected in October
- LEFD006 is part of a two-hole diamond program that is expected to conclude in August
Burns is a new and unique style of an intrusion-related gold (Au}- copper (Cu)-molybdenum (Mo) mineral system hosted by Archean age rocks in the Eastern Goldfields Province (EGP) of Western Australia, with understanding of the scale and genesis of the system to be advanced through this deep drilling program.
The gold, copper (and lesser molybdenum) mineralisation hosted by both the diorite porphyry, high- magnesium basalt and massive magnetite veins are considered by the Company to be a new and unique style of gold-copper mineralisation near Kalgoorlie and located within a land holding dominated by LEX.
Diamond Drill Program
The first hole, LEFD006 (Table 1), of the two-hole/1650m diamond drill program (Figure 1) commenced on 12 July (Refer LEX ASX release 12 July 2022).
LEFD006 is designed to evaluate the Burns Au-Cu mineralised diorite porphyry host rock to a target (vertical) depth of 1000m from surface with key aims to:
- Expand the continuity of the mineralisation discovered to date on a vertical scale
- Test the lateral extent of the system by 250m west of the main known mineralisation
- Provide geological and geochemical information to support ongoing research
- Demonstrate further that Burns is a new, large Au-Cu intrusion hosted mineral system
As of July 29, LEFD006 has intersected a 570m interval of predominantly high-Mg basalt. The wide basalt interval is variably epidote-biotite-magnetite-gypsum altered (Figure 3 and 5) with localised hydrothermal breccia intervals and narrow cross-cutting porphyry intervals. Within this is a new, unexpected 40m interval of multi-phase diorite porphyry intrusives.
Mineralisation within the basalt interval includes fracture-fill native copper (Figure 4) from ~180m in fresh basalt down to a downhole depth of 440m with vein and/or fracture-fill chalcopyrite, pyrite, chalcocite and molybdenite (Table 2). This wide downhole interval of altered basalt has increased the lateral extent of the copper mineralised Western Basalt zone by approximately 250m. The alteration assemblage supports a large hydrothermal alteration cell consistent with an intrusion related system.

Western Australia’s DEMIRS Launches New Online System for Environmental Approvals
The Western Australia Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) is launching a new platform for state environmental approvals, the department announced on August 22.
The Resources Online platform will be a single-user portal that will provide better customer experiences and improve business processes when lodging environment applications under the Mining Act 1978 and state petroleum legislation.
“It will ultimately replace the current Environmental Assessment and Regulatory System,” DEMIRS said, adding that the portal is a key deliverable under the department’s Fast-tracking Mining Approvals program, which “aims to significantly expand and improve the digital capability of mining and petroleum environmental lodgements.”
Targeting improved assessment timeframes and efficiency, the department said it has been working closely with stakeholders to ensure that the new product meets the mining sector's needs.
An industry-wide survey was opened on February 28 to gather insights that were then used to inform the design and department processes around the system. Responses were collected until March 15.
An industry working group consisting of participants from across the resource sector was also established to ensure that a variety of requirements and perspectives were addressed.
“Our goal was to ensure applications are submitted and assessed as efficiently as possible, so it was essential we worked closely with industry,” said Tyler Sujdovic, DEMIRS' executive director, resource and environmental compliance.
“The feedback we have been receiving from the working group has been encouraging,” he continued. “It tells us we are on the right track, and we are looking forward to welcoming the group back to test the system before going live.”
Resources Online is expected to launch at the end of September. DEMIRS said it is following a phased implementation approach, and the first release will be for Programme of Works applications.

Allup Appoints IHC Mining Consultants for McLaren PFS
Allup Silica Limited (ASX: APS) (“Allup” or “Company”) is pleased to announce it has appointed IHC Mining (IHC) to undertake a Pre- Feasibility Study( PFS) for the McLaren Mineral Sands Project in Western Australia.
Allup announced its acquisition of the advanced-stage McLaren Project earlier this month, which has an Indicated and Inferred JORC (2012) resource of 280Mt at 4.8% Heavy Mineral1 near surface. Allup is examining its potential to produce ilmenite, a key titanium mineral, which currently trades at more than US$300/t due to increasing titanium shortages. Strong ilmenite market demand expected to continue due to supply deficits and mine closures in Africa.
Whilst process optimisation of the McLaren plant will continue following the completion of test work, flow sheet development and basic engineering have already commenced. At this conceptual stage, the Company’s PFS is progressing with a focus on a medium sized, 10Mtpa spiral concentration plant, which could produce up to 400,000tpa of ilmenite in concentrate annually.
IHC has significant expertise in the design, engineering and construction of mineral sands processing plants, and has a significant laboratory, mineral processing and engineering group based in Queensland.
Its design optimisation work at McLaren will continue through the engineering and design stages.
Allup aims to deliver the PFS in Q2 2025, before moving into the Bankable Feasibility design phase.

Large Copper - Antimony System at Bulla Park
West Cobar’s (ASX:WC1) 100%-owned Bulla Park Copper Project 110km west of Cobar in New South Wales, contains a large copper – antimony system as indicated by previous drill intersections.
Highlights
- Previous diamond drilling shows broad intervals of disseminated copper - antimony mineralisation
- Previous intercepts have contained significant sulphidic copper and antimony mineralisation, such as:
- 89m at 0.30% Cu and 0.10% Sb, including 33m at 0.47% Cu and 0.15% Sb (19CA002, 176m to 265m)
- Copper grades up to 1.46% Cu (19CA002, 246m to 247m)*
- Antimony grades up to 0.5% Sb (19CA002, 246m to 247m)*
- Copper and antimony grades increase towards a broad zone of faulting targeted by recently drilled diamond hole BPD09 (assays awaited)
Mineralisation is dominantly tetrahedrite (copper - antimony sulphide) and minor chalcopyrite and stibnite (antimony sulphide). Antimony grades in previously assayed drill hole intercepts are approximately 30% to 35% of the copper grade, reflecting the theoretical composition of tetrahedrite (Cu12Sb4S13).
Recently drilled BPD09 (see ASX release of 13 August 2024) was designed to test an interpreted fault zone where higher copper – antimony grades were anticipated. The hole successfully intersected a broad zone from 120m to 338m (218m) of faulting, fracturing, disseminated copper- antimony sulphides, siderite alteration, veining and stockworks, and tectonic and hydrothermal breccias. The core samples from BPD09 are currently in a laboratory undergoing preparation. Assay results are expected to be received during September.
* See Appendix 1 for complete Cu and Sb assays for drill hole 19CA002
Antimony grades at Bulla Park follow the copper distribution. High grades of copper are found with better antimony grades. Apart from the dominant antimony mineral tetrahedrite, stibnite occurs as radiating needles in fractures and makes up about 10% of the antimony content.
Further drilling is planned to extend the major fault zone containing broad intervals of disseminated copper-antimony mineralisation.
Antimony
Antimony (Sb) is a designated critical mineral in many countries and is used in military applications, solar cells, fire retardants and as a strengthening agent in alloy production.
China supplies 56% of the global antimony production and has decided to restrict exports of antimony from 15 September 2024, claiming that its strategic reserves are too low to allow further exports. This has caused the price of antimony to increase significantly to approximately US$23,000/t as USA and European users seek to secure supply. (source: www.reuters.com)
Previous Results at Bulla Park
A characteristic of the Bulla Park deposit is consistency of copper and antimony grades over wide intervals (historical drilling intersected stratabound zones outside of the fault zone, where better grades are anticipated).
Table 1: Summary of historical assay results of copper-antimony mineralisationResults reported using 0.2%Cu cut-off
In previous drilling, both the copper and the antimony grades increase towards the newly intersected fault zone recently targeted by BPD09 (assays awaited). The nearest previously drilled historical hole to the fault zone is 19CA002, which includes 7m of 0.27%Sb and 0.71% Cu from 245m.*
