Drilling extends shallow gold discovery at Harmonic prospect

TSC Limited (ASX: TSC) (“TSC” or “the Company”) is pleased to report further shallow gold, up to 5.5g/t Au, was discovered at the Harmonic prospect. This follows receipt of assays for 11 drill-holes (six Harmonic / five Creasy 1 prospects) from the March 2020 RC drilling campaign, which comprised 20 drill-holes for 1,752m.


  • New assays, with grades up to 5.5g/t Au, from the recent RC drilling campaign confirm a new discovery at the Harmonic prospect, which is 500m north of Creasy 1 where there is known high-grade shallow gold mineralisation  

  • Significant intercepts at the Harmonic prospect include:  

    • 6m @ 2.9g/t Au from 44m (20RVRC020) including: 

      •  3m @ 4.9g/t Au from 44m  

      • 3m @ 5.5g/t Au from 59m  

      • 3m @ 1.1 g/t Au from 32m*  

    • 5m @ 1.3g/t Au from surface (20RVRC018)* 

    • 3m @ 1.4g/t Au from 26m (20RVRC022)* 

    • 3m @ 1.9g/t Au from 77m & 3m @ 1.4g/t Au from 101m (20RVRC023)*  

    • 9m @ 1.4g/t Au including 1m @ 7.25g/t from 58m (19RVRC007)#  

    • 14m @ 1.0g/t Au including 2m @ 3.3g/t Au & 21.2g/t Ag from 26m (19RVRC008)#  

  • Further, the assays verify gold mineralisation which starts at surface in the north and extends over a 180m strike length and remains open along strike and down dip 

  • At this stage of TSC’s exploration program, it’s significant to have high-grade shallow gold discoveries at the Harmonic and Creasy 1 prospects – which are half a kilometre apart  

  • Of the 20 RC drill-holes (1,752m) completed in the recent RC drilling campaign, the remaining nine outstanding assays will provide more clarity on the shallow highgrade gold discovery at the Creasy 1 prospect  

  • Once all assays and ground electromagnetic results are received, TSC expects to progress further follow up RC drilling later in the current quarter 


CEO Ian Warland commented: “The real surprise from these initial assays is discovering gold at surface and the extent of shallow high-grade gold mineralisation at the Harmonic prospect. There is now clear confirmation that gold mineralisation extends over 180m along strike, remaining open down dip and along strike. More importantly, TSC now has two high-grade gold discoveries, 500m apart, that can be further explored. Looking forward, the remaining nine assays, which are due shortly, will provide more clarity on the extent of shallow gold mineralisation at the Creasy 1 prospect at two high-grade focus areas.”
