Rome Resources reports encouraging testing results from DRC project
Aim-listed Rome Resources has reported encouraging results for copper and tin from metallurgical testing of ore samples from its Bisie North project, in the Democratic Republic of Congo (DRC).
This update on the initial results follows a previous drilling update from January 16.
“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,” CEO Paul Barrett points out.
Metallurgical testing was undertaken by SGS on bulk samples from the tin, copper and zinc zones to assess the potential for commercial recovery of the various commodity metals from the ore. The results for copper and tin recovery are encouraging.
The tin zone sample has responded well to gravity pre-concentration with 80% of the tin reporting to a first concentrate at a grade of over 10% tin from a head grade of 0.6% tin in less than 5% of the mass.
The copper zone sample has also responded well to gravity pre-concentration with 96% of the copper reporting to a concentrate at a grade of 3.7% copper from a head grade of 2.4% copper in less than 63% of the mass.
The copper sample responded well to flotation with 95.5% of the copper reporting to the rougher flotation at a grade of 9.5% copper. The zinc in this sample followed the copper and differential flotation may therefore be considered to separate the copper and zinc, the company explains.
In all cases, customary cleaning of the tin and copper concentrates will be required to raise the grade to export levels.
Currently, the drilling campaign at Kalayi continues and the company will move to Mont Agoma next month to test further the extent of the tin and copper mineralisation, Barret informs.
