Sandfire said the “outstanding” new results show the zone of mineralisation now extends to 700 metres as opposed to the 250 metres previously calculated.
Among the main samples, there were 18 metres at 5.2% copper and 124 grammes per tonne of silver, as well as 21 metres at 2.4% copper and 64 grammes per tonne of silver.
Sandfire added that initial resource drilling programme was progressing “well” but had to be interrupted in late March after Botswana implemented a lockdown to prevent the spread of coronavirus.
Operations will resume once restrictions are lifted.
Data has been re-processed and re-interpreted by Sandfire, which identified “several” new high-priority structural targets for drilling.
“Sandfire’s A4 drilling results from Tshukudu are very encouraging and we look forward to drilling resuming in Botswana, both for Sandfire and Kalahari Metals,” said Michael McNeilly, chief executive at Metal Tiger in a statement.
“Kalahari Metals, in which Metal Tiger has a 62.2% interest, has tenements located near T3 and A4 and we believe to be in the right stratigraphy.”
Metal Tiger holds 6mln shares in Sandfire, representing approximately 3.64% of its issued share capital.
Metal Tiger shares shot up 14% to 1.37p on Friday at noon.
