Star Minerals Limited (ASX: SMS, “the Company” or “Star Minerals”) is pleased to provide its Quarterly Activities Report for the period ended 31 December 2023.
HIGHLIGHTS
Tumblegum South Gold Project Scoping Study Completed
- The Scoping Study presented a range of outcomes for open-pit mining and third-party toll treatment of the Tumblegum South gold deposit (“Tumblegum South” or “the Project”) which is located approximately 40km south of Meekatharra in the Murchison district of Western Australia.
- The positive results of this Scoping Study provide a basis to refine material inputs and enhance project economics for the Tumblegum South gold resource.
West Bryah Copper Gold Project
- Comprehensive data review underway incorporating additional tenements.
Corporate
- Placement; $600,000 private placement completed.
- $583k cash at bank as at 31 December 2023.
Corporate
A placement of ordinary shares to new and existing sophisticated investors was completed, raising $600,000 at 4 cents per share.1 Shares were issued following shareholder approval obtained at the general meeting of shareholders, held on 18 October 2023.
Participants in the placement received one free attaching option for every one ordinary share subscribed for. The unlisted options are exercisable at 6 cents and expire on 31 October 2026.
Funds raised from the placement allow the Company to advance scoping and environmental studies at the Company’s Tumblegum South gold Project, exploration activities at the West Bryah copper gold Project and provide additional working capital.
At the end of the quarter, the Company had $583k cash at bank. Included in the Appendix 5B – Section 6 are amounts paid to the Directors of the Company during the December quarter totalling $19,050 comprising director remuneration, including superannuation.
The Company has two projects, a gold Mineral Resource at Tumblegum South, 40km south of Meekatharra and the West Bryah copper-gold exploration project, 120km northwest of Meekatharra.

Tumblegum South Gold Project – Scoping Study2
Various options utilising third-party processing plants operating under a toll treatment agreement were considered. There are currently two active processing plants within a radius of 50km to 150km from Tumblegum South. A range of outcomes were defined based on gold price, and processing cost including trucking costs.
- At gold prices from AUD$2,250 to AUD$3,000/oz, the Production Target for the Project ranges from approximately:
- 116kt at 2.25g/t producing 7.6koz gold, to
- 286kt at 2.00g/t producing 16.6koz gold.
- The Production Target generates an undiscounted accumulated cash surplus after payment of all working capital costs, but excluding pre-mining capital requirements, of approximately $7.2M to $16.3M.
- Mining is contemplated as a single campaign over approximately 18-months.
- Pre-mining capital and start-up costs are estimated to be approximately $0.7M to $1.5M.
- Sensitivity of the Base Case scenario to gold price was assessed. Results suggest that project economics are robust for a broad range of gold prices.

EIS Grant for Minnie Springs Copper Porphyry Drilling
- Augustus Minerals has been granted a co-funded drilling grant of up to $110,000 for 2 x 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
- The deeper diamond drill program is designed to test and to provide a 550m deep, 1km wide geological/geochemical/structural cross-section through the large 3km long by 1km wide copper moly porphyry system, linking the Mo mineralised leucogranite to the extensive Cu in soil anomaly to the northeast.
- Previous RC drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a large porphyry copper / moly system.
Andrew Ford, GM Exploration
“The Company is pleased to receive an EIS grant to complete deeper drilling at the Minnie Springs Copper Molybdenum Project. The resultant data will enable mapping of the lithology and alteration to a depth of 550m and potentially intersect, or provide vectors to, higher grade Mo-Cu mineralisation using a Mo-Cu porphyry geological model”.
Minnie Springs
Minnie Springs hosts porphyry related copper molybdenum mineralisation previously drilled and defined by Catalyst Metals. A molybdenum Exploration target has been defined for the historicdrillingareacomprisedofbetween12-84Mtasoutlinedbelow (Table 1 and Figure 1, 2.)1.
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm cut-off at 100% recovery.
The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The planned diamond drilling will complement the recently completed 3,200m RC drilling program that infilled around hole MSRC012 (18m @ 0.37% Cu and 9.7 g/t Ag from 94m downhole, and 16m @ 0.38% Cu and 19.4g/t Ag from 121m downhole2) and tested the northern half of the 2km long copper-in soil anomaly. Assays from this program are expected to become available over the next month.
The limited exploration in the region, highlighted by 95% of the Ti-Tree project having no previous exploration, demonstrates the prospectivity of this underexplored mineral province.

Quarterly Activity Report 31 March 2024
Figure 1. Fiery Creek Copper Prospect/Yataga Granodiorite summarizing rock (brown diamonds) and termite mound sample results (black crosses)
Continuing with its primary exploration focus on the Georgetown project in the latter half of 2023, EMU received assay results during the quarter from its second, in field reconnaissance work. The geochemical sampling programme covered the Fiery Creek high grade copper vein swarm and the Snake Creek prospects with significant element results returned from the Fiery Creek Copper (elevated Cu-Au-Ag-Bi-In-Pb-Sb-Te) and Snake Creek (elevated Pb-Ag-Au-Sb).
Whilst the survey was cut short due to inclement weather, EMU was encouraged by the significant success reflected in the assays results. The results from mineralogical studies confirmed EMU’s interpretation of an indicative, scale Copper-Porphyry system at the Fiery Creek prospect and was a highlight of the survey with new information building on the scale and potential of the prospect1.
Assay results returned included:
- Fiery Creek rock assay results up to 23.5% Cu, 0.27ppm Au, 460ppm Ag, 1.9% Bi, 89ppm In, 2.7% Pb, 667ppm Sb, 1470ppm Zn2.
- evidence of strong potential for the presence of critical and strategic minerals (Cu, Bi, In), with precious and base metals.
- evidence of alteration mineralogy, mineralisation geochemistry and areal extent of the Fiery Creek quartz-Cu-Bi vein swarm strongly suggesting a previously unrecognised subjacent porphyry Cu-Mo system.
- Yataga Granitoid Complex termite mound and coincident rock chip sampling returned several anomalous polymetallic zones for follow up.
- Snake Creek Prospect assays returned 0.20ppm Au, 390ppm Ag, 22.4% Pb, 464ppm Sb1.
Significant results were returned from the Fiery Creek Copper prospect with elevated Cu-Au- Ag-Bi-In-Pb-Sb-Te and from the Snake Creek prospect with elevated Pb-Ag-Au-Sb.
The elevated pathfinder element results and a macro-petrology assessment3 of rock samples completed by Mr Nigel Maund, Consulting Economic Geologist, from the previously unexplored Fiery Creek Prospect, point to the discovery of a porphyry copper system.
The sampling program assessed a number of high-priority prospects within the Georgetown Project tenements utilising termite mound and outcrop rock chip geochemistry. A total of 46 rock chip and 489 termite mound samples were collected across eight prospects.
