Initial Tin and Copper Metallurgy Testing Results
Rome Resources plc has announced encouraging initial metallurgical testing results for its Bisie North project in the DRC, located near the Alphamin Mpama tin mine. The tin zone sample showed 80% of tin reporting to a concentrate at over 10% Sn from a 0.6% Sn head grade, while the copper zone sample achieved 96% of copper reporting to a concentrate at 3.7% Cu from a 2.4% Cu head grade using gravity pre-concentration. Further flotation tests on the copper sample yielded 95.5% of copper reporting to a rougher flotation at 9.5% Cu, with zinc also following the copper, suggesting potential for differential flotation. These results are considered highly encouraging for the commercialisation of both tin and copper at the project. Disclaimer*
About this update from Rome Resources Plc
[{"type":"text","content":"\n\n2 February 2026\n \nRome Resources plc\n(\"Rome Resources\" or the \"Company\")\n \nInitial Tin and Copper Metallurgy Testing Results\n \nRome Resources plc (AIM: RMR), the DRC-focused tin and copper explorer, is pleased to provide an update on the initial results from metallurgical testing of ore samples from its Bisie North project in the Democratic Republic of Congo (\"DRC\"), located just 8 km from the world-class Alphamin Mpama tin mine complex. This update follows the drilling update provided on 16 January 2026.\n \nMetallurgical testing was undertaken by SGS on bulk samples from the tin, copper and zinc zones in order to assess the potential for commercial recovery of the various commodity metals from the ore. The results for copper and tin recovery are encouraging.\n \n· The tin zone sample has responded well to gravity pre-concentration with 80% of the Sn reporting to a first concentrate at a grade of over 10% Sn from a head grade of 0.6% Sn in less than 5% of the mass.\n \n· The copper zone sample has also responded well to gravity pre-concentration with 96% of the Cu reporting to a concentrate at a grade of 3.7% Cu from a head grade of 2.4% Cu in less than 63% of the mass.\n \n· The copper sample responded very well to flotation with 95.5% of the Cu reporting to the rougher flotation at a grade of 9.5% Cu. The Zn in this sample followed the Cu and differential flotation may therefore be considered to separate the Cu and Zn.\n \nIn all cases customary cleaning of the tin and copper concentrates will be required in order to raise the grade to export levels.\n \nPaul Barrett, Chief Executive Officer of Rome Resources, said:\n\"These preliminary results are highly encouraging for the potential commercialisation of both the tin and copper at Bisie North. As the copper is developed at shallow depths in the Mont Agoma deposit, recovery and monetisation of this is expected to be highly accretive to the overall project economics.\n \nCurrently, the drilling campaign at Kalayi continues and we will move to Mont Agoma next month to test further the extent of the tin and copper mineralisation. We will update the market in due course.\"\n \nFor further information, please contact:\n \n \n\n\n\n\n...
