The assay results come from a hole drilled 2.5 kilometres along strike to the west of the resource.
It was re-entered based on a revised geological model that tested for peripheral mineralisation.
Assays include 17 metres at 3.18% lead, 2.91% zinc and 42 g/t silver from 350 metres, and 12 metres at 4.01% lead, 3.02% zinc and 47 g/t silver from 351 metres.
Chalcopyrite-rich mineralisation intercepted
Following confirmation of the peripheral mineralisation, a second hole was successfully positioned and intercepted around 20 metres of overprinting chalcopyrite-rich mineralisation.
The entire 20 metre interval is estimated at around 40% total sulphide content.
It comprises overprinting chalcopyrite and interpreted cobaltiferous pyrite with layers of massive pyrite, semi-massive pyrite, laminated pyrite and inter-fingered siltstone and shale horizons.
A similar hole drilled a further 1.2 kilometres to the west hit a similar chalcopyrite-rich interval.
Results confirm geological model
These intercepts confirm the presence of mineralisation seen within the current resource as well as the revised geological model from 2017.
The drilling campaign commenced in April utilising three drill rigs to drill at least 30 kilometres to advance the known mineralisation to development status.
It also aimed to test the potential extension of the current resources on the company’s tenements.
The Walford geological model first announced in July 2017 is closely associated with the sediment hosted copper-cobalt style mineralisation of the Zambian Copperbelt in Africa.
