[{"type":"text","content":"\n\n12 September 2023\n \n \nTertiary Minerals plc (\"Tertiary\" or \"the Company\")\n \nPROVISIONAL SOIL SAMPLING RESULTS\nMUKAI COPPER PROJECT, ZAMBIA\n \nThe Company is pleased to announce that portable XRF analysis of soil samples has defined a substantial copper-in-soil anomaly at the Mukai Copper Project in Zambia.\n\nKey Points:\n· A total of 526 samples were collected on a 300m x 100m grid infilled up to 100m x 50m and analysed in the field using a portable XRF instrument (\"pXRF1\").\n \n· A large high-grade copper-in-soil anomaly is defined with values in excess of a 160ppm copper over an area of approximately 1,300m by 400m with a peak soil value of 1,660ppm copper (0.16%) and soil values averaging 252ppm (average of 63 samples).\n \n· This high-grade anomaly is part of broader copper-in-soil anomaly defined by 162 samples containing greater than 80ppm copper and averaging 173ppm copper over an area of approximately 1,800m by 800m.\n \n· Soil anomalies from past producing mines on the Copperbelt typically have thresholds in the range 50 to 150ppm copper, averaging 80ppm copper and peak values in the range 100-450ppm copper and averaging 210ppm copper.\n \n· A subset of samples will now be submitted for laboratory-based check analysis.\n \n· The option and earn-in periods at Mukai and Mushima North Projects have been extended by six months by agreement with local partner Mwashia Resources to account for earlier delays with forest permits. \n \n Commenting today, Executive Chairman Patrick Cheetham said:\n\"I am delighted to announce the definition of a large soil anomaly at Mukai with very high values of copper-in-soil based on pXRF analysis. The anomaly stretches to our property boundary with mining licences owned by First Quantum Minerals as part of the Trident mining complex and where soils have a lower copper content but where, nevertheless, drilling has found significant copper sulphide mineralisation. This enhances the prospectivity of the main part of the anomaly on the Mukai licence which now presents an exciting target for drill testing.\"\n\"Looking to other projects in Zambia we are currently completing pXRF analysis of infill samples f...
