Star Minerals Limited (ASX: SMS, “the Company” or “Star Minerals”) is pleased to advise that it has received the assay results from its phase 2 reverse circulation (RC) gold drilling campaign at the “Star of the East” project.
HIGHLIGHTS
- Gold assays received for phase 2 reverse circulation drilling at Star of the East
- Phase 2 drilling assays include:
- 5m @ 2.45 g/t Au in hole SRC017 from 9m downhole
including 3m @ 3.16 g/t Au from 10m downhole - 3m @ 3.24 g/t Au in hole SRC009 from 52m downhole
- 3m @ 2.68 g/t Au in hole SRC010 from 34m downhole
- 5m @ 2.45 g/t Au in hole SRC017 from 9m downhole
- Drilling was designed to extend known mineralisation at the Prospect
- Review of the model is in progress to support final Project evaluation
Star Minerals’ Chair, Ian Stuart commented:
“The drill program at Star of the East was efficiently executed, with a strategy to test the deposit for extensions.
Project review on the available data, as validated by Star Mineral’s drill testing during phase 1 and now phase 2 is in progress to evaluate the potential value of the deposit.”
The phase 2 drilling program consisted of 10 RC holes which were completed for a total of 757m. Including the phase 1 drilling of 294m over 7 holes, Star Minerals have now drilled a total of 17 holes for 1,051m of RC drilling, to ensure a considered evaluation of the Star of the East Project is completed.
Star of the East is a historic high-grade gold mine in the Murchison region of Western Australia, first mined in 1897 after discovery by prospectors. Tenement E51/1561 contains evidence of this historic work, with an old shaft and other remnants of previous activity. Records indicate that the mine produced around 27,700oz gold, working along a main lode down to around 50m depth.1
Drilling has tested extensions of the Star of the East gold deposit to the east, west and down dip of the existing high density of drilling focused on the turn of the 19th Century mining works in the shallow portion of the deposit.
Star Minerals has right to drill at the Star of the East Project due to an access agreement signed as part of an option agreement for the Project with the holders of the tenement.

Intercepts of significance from phase 2 drilling include:
- 5m@ 2.45 g/t Au from 9m depth on hole SRC017, including:
- 3m @ 3.16 g/t Au from 10m depth
- 3m @ 3.24 g/t Au from 52m depth on hole SRC009
- 3m @ 2.68 g/t Au from 34m depth on hole SRC010.

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.
