Tertiary Minerals (AIM:TYM) Exploration Update – Jacks Copper Project, Zambia

Tertiary Minerals plc (LON: TYM), the AIM traded mineral exploration and development company is pleased to announce the start of a detailed soil sampling programme at the Jacks Copper Project (“Jacks”) in Zambia, where Tertiary has now earned a 90% joint venture interest from local Company Mwashia Resources Ltd.


·Detailed soil sampling planned for four separate areas to include:

  • A 5.3 sq.km. area surrounding the copper mineralisation recently intersected in drilling at the Jacks Copper Prospect (announced 29 June 2022).
  • Infill sampling in key areas of a 15km long soil anomaly defined by Cyprus


  • Infill sampling of Copper:Scandium (“Cu:Sc”) soil anomalies in two areas defined in wide-spaced soil sampling by First Quantum Minerals (“FQM”).
  • Tribal & Stakeholder engagement successfully completed.
  • Up to approx. 1,600 samples to be collected on a 200m x 40m grid with initial field analysis of samples using portable XRF analyser (“pXRF”) delivering results in real time.

Commenting today, Executive Chairman Patrick Cheetham said:

“The announcement of this programme highlights the growing momentum of our exploration programmes in Zambia following the successful drilling programme at Jacks this summer and the recent announcement of our collaborative agreement with First Quantum Minerals.

The soil sampling programme at Jacks is targeting extensions to the known copper mineralisation as well as areas defined during wide-spaced soil sampling by FQM as having high Cu:Sc ratios which can indicate the presence of copper sulphide minerals in potentially economic concentrations.”
