Twenty Seven Co. Limited (TSC) is currently undertaking its maiden RC drilling program at Mt Dimer Mining lease in Western Australia.


  • The Mt Dimer Gold Project comprises a mining lease (M77/515) and exploration license (E77/2383) located circa 100km North-East of Southern Cross (see the map on the right). To recap, the Mt Dimer mining lease was last mined in the mid-1990’s when the gold price was circa A$500 per ounce. The open pit produced ~77,000t @ 3.44g/t Au for circa 8,500 Oz of Au, to 50m depth. (Reference: ASX: TSC: 30 September 2020, Strong gold potential at Mt Dimer)
  • No significant production or exploration work has been completed since 1996. Historical drilling from the 1990’s and four drill-holes from 2017 indicate that significant gold mineralisation exists under the open pit and along strike. A north-south long section through the Mt Dimer deposit indicates gold mineralisation plunging shallowly south below the current pit level and remaining open at depth.
  • TSC’s Mt Dimer project sits just over 1 hour North of Great Eastern Highway, to the North West of the famous gold mining town of Southern Cross.
  • As well as the project’s close proximity to the major highway and power it’s sits within a two hour drive from the major Gold Mining centre of Kalgoorlie.
  • Mt Dimer’s Mining Lease expires in 2034.
