Teal was conducting a 5 200-m exploration drilling programme at Lupoto to verify and update the historical resource.
Borehole D-001 has confirmed the historical interpretation of the upper zones of mineralisation as 2,7 m grading 11,20% copper, and 13 m at 6,44% copper, in the south-eastern area of the main Lupoto structure, the company said.
Teal believed the mineralisation was open-ended at depth. Current drilling was targeting the shallow and predominately oxide copper enrichment.
Further, Teal announced that it was targeting a portion of the drilled mineral resource, totalling 560 000 t at Lupoto, for immediate small-scale mining.
The company was anticipating an operation that mined at a rate of 70 000 m3 a month and was expecting to produce over 20 000 t a year of concentrate, grading 25% copper, containing at least 5 000 t of copper.
The concentrate would be produced through selective mining and, initially, upgrading by hand-sorting.
The mining contractor at Lupoto had completed pre-stripping the overburden, and was building up to planned full production, the company said in a statement.
Teal intended selling the concentrate to existing smelter operators in the DRC and feeding its own electric arc furnace, which was scheduled to start commissioning over the next few weeks.
Teal is a mineral development and exploration company with development projects and exploration areas in Namibia, Zambia and the DRC.
