Arc Minerals Limited (AIM:ARCM, OTC:ACMNF, FRA:DFYA) told investors it has mapped an 18-kilometre geological contact at its Virgo copper project in Botswana, expanding the prospective structure by 14 kilometres ahead of drilling scheduled to start in early August.
The induced polarisation survey identified several high-priority chargeability and resistivity anomalies, alongside areas of structural complexity that may act as mineral trap sites. The inferred contact between the D’Kar and Ngwako Pan formations is now more than four times longer than the company had previously expected.
Chief executive Remy Welschinger said the structure lies within metres of MMG’s Mawana Fold and Zone 9 discoveries in the Khoemacau mining project. Arc said the survey findings remain qualitative exploration targets and require geological testing through drilling.
The company is finalising its choice of drilling contractor. Welschinger will also present an update on the Virgo project through Investor Meet Company on 30 July at 4.30pm BST.
