Prospects

Jacks Creek – Gold

  • Historic drilling (1990-91) over 1.3km strike, with all drilling very shallow (15-24m, deepest 39m below surface). Highlights include:                                                                         
    • 7m @ 2.47g/t Au from 6m     7m @ 1.73g/t Au from 11m
    • 7m @ 1.25g/t Au from 4m     7m @ 1.01g/t Au from 11m
    • 6m @ 1.72g/t Au from 25m   5m @ 4.23g/t Au from 9m
    • 5m @ 2.98g/t Au from 21m   4m @ 1.96g/t Au from 11m
    • 3m @ 4.22g/t Au from 22m   2m @ 3.36g/t Au from 46m (EoH)

  • Jacks Creek Extensions: Jacks Creek North & South stream sediment sampling has identified gold anomalies over a strike of 15km, with the southern area possibly having a better host rock as indicated by a magnetic anomaly which suggests mafic-ultramafic lithologies                                         
  • Note – Historic drilling based solely on Arsenic soil anomalies (no Au assays completed prior to drilling) – potential displacement from main gold mineralisation

    Prospect Locations and known Gold, REE, Nickel, Cobalt and Tungsten mineralisation within EPM 26360. Rock Chips at Jacks Creek up to 10.95g/t Au.

    Jacks Creek – Gold

    • Gold and multi-element soil sampling (5 traverses) was completed for first time at Jacks Creek by Sturt in October 2021. Very high-grade Au (+/- As and Sb) results up to 459ppb outlined. Open to north and south.

    • Main high-grade Au zone immediately east of regional N-S trending regional scale fault. Lower-grade Au zone (to 43ppb Au) west of fault also outlined.

    • Subsequent campaigns by Sturt in 2023-24 has taken the number of of infill and extensional soil traverses to 36 with Au results up to 534ppb

    • Detailed and reconnaissance soil programs (and rock chip) planned to extend zones and identify more anomalies along the full strike of Jacks Creek fault

    • Maiden RC and diamond core drilling campaigns planned

    Jacks Creek (looking north). Note – easy track access to site, historic PVC collars. Also shown are historic dillhole collars (circa 1990-91) which will be rehabilitated after planned SEM RC/core drilling.

    Jacks Creek – Gold

    • Discovered by regional stream sediment sampling, with all subsequent drilling very shallow (~18m below surface).
    • Lynch Mining completed, Arsenic (As) only, detailed soil sampling at Jacks Creek circa 1989-90
    • Lynch Mining completed percussion drilling at Jacks Creek 1990-91 (over 1.3km strike), although all drilling very shallow (typically 15-24m) with drillhole JC034 the deepest 39m below surface – 2m @ 5.28g/t Au stopped in mineralisation
    • Gold and multi-element soil sampling (16 traverses) completed by Sturt 2021-24 (first multi-element soil survey at Jacks Creek)
    • Outlined an extensive very high-grade gold and srsenic anomaly (+/- Sb), which is clearly still open to north and south
    • Sturt has completed 901 samples to date with gold to 534ppb (Arsenic to 1,042ppm)
    • Stream sediment sampling followed by soil sampling are rapid cost-effective techniques to target gold mineralisation at Jacks Creek
    • Multiple drill ready targets on the Au (and As) soil grid
    • Gold and multi-element soil sampling required along full length of Jacks Creek fault (circa 15km strike) and infill sampling on current soil grid prior to drill testing
