Power Metal Resources PLC (LON:POW) said additional sampling at the Morula target at South Ghanzi in Botswana had increased the size of the identified anomaly to 18km.
South Ghanzi is being developed through a 50/50 Joint Venture with Kavango Resources PLC (LON:KAV), which is the operator.
The Morula Target geochemical anomaly is now over 18km long (up from 12km previously announced on 21 June 2021) and varies between 800m and 2.4km in width and is open along strike in both directions towards the northeast and southwest, said the statement.
In addition to this, a third sub-parallel geochemical anomaly has been identified immediately to the south of the Morula target approximately 5km long and approximately 700m wide.
Paul Johnson, Power Metal Resources chief executive, said: "The current 18km length of the Morula Target is dramatic, particularly as the target remains open in both directions.
“Alongside this, the discovery of a further geochemical anomaly named "Happy", is another surprising and positive development at South Ghanzi.
“What is also encouraging is that we are seeing strong coincidence between the copper-zinc geochemical anomalism with previously defined airborne electromagnetic ("AEM") conductors.”
