[{"type":"text","content":"\n\n \n\n \n25 June 2025\nTertiary Minerals plc\n (\"Tertiary\" or the \"Company\")\n \nProject update: Konkola West Copper Project, Zambia\n \nTertiary Minerals plc (AIM: TYM) is pleased to provide the following update on the current drill programme being undertaken by a subsidiary of KoBold Metals (\"KoBold\") at its Konkola West Copper Project (\"Konkola West\" or the \"Project\"), Zambia. KoBold has the right to earn into the Project by drilling two drill holes for a minimum of 2,000m (for further details see below and the Company's news release dated 19 December 2023).\nKoBold is targeting the potential continuations of mineralisation being mined at the world-class Musoshi, Lubambe and Konkola Mines, which had a pre-mining combined endowment of over 775Mt grading 2-3% copper. KoBold's large and high-grade Mingomba copper project is located approximately 5km to the northeast of the Project.\n \nDrilling Update\n \nKWDD001\nHole KWDD001 was collared in the northeast of the licence and was drilled to a depth of 2,711m where it was terminated due to continued technical difficulties prior to reaching the targeted horizon (Ore Shale, Copperbelt Orebody Member). KWDD001 is believed to be the deepest mineral exploration drill hole to have ever been drilled in the Zambian Copperbelt and marks a significant milestone within the industry.\nFull geochemical assay results have now been received for part of the hole (107.9m to 1837m and 2,664m to 2,711.6m). The remaining assays (0m to 107.9m and 1,837 to 2,664m) are expected from the external laboratory shortly.\nVisible copper mineralisation, as reported in the Company's news release dated 31 March 2025, returned anomalous copper values commensurate with the observed visual estimates of chalcopyrite and bornite:\n· 232.23m - 233.28m: 2,950ppm copper over 1.05m.\n· 2,670m - 2,695m: copper values of up to 1,050ppm.\nThe wider geochemical data is being used to further the understanding of fluid dynamics, aiding stratigraphic correlation, and characterize alteration within the target sedimentary basin.\n \nKWDD002\nHole KWDD002 is collared on the eastern side of the licence and is targeting down-dip extensions of known mineralisation (Figure 1). KoBold commenced drilling of KWDD002 on 26 March 2025 and drilling has ...
