Krakatoa Resources Limited (ASX: KTA) has commenced an Unmanned Aerial Vehicle (UAV) magnetics survey on the company’s Bell Valley Target at the company’s Belgravia Project in NSW.
Executive Chairman, Colin Locke, said the Bell Valley is prospective for porphyry Cu-Au and associated skarn Cu-Au mineralisation and represents one of six initial targets on the Belgravia Project.
Current activities are focused on the Bella Prospect, a “doughnut” shaped magnetic pattern considered characteristic of porphyry intrusion, present within the Bell Valley target.
The survey utilising Thomson Aviation’s UAV drone technology is being flown at a flight height between 30m – 35m, on 25m line spacing in an east- west direction with tie lines every 250m in a north-south direction.
The survey will result in over 320km line kilometres of data which is expected to highlight variations in local magnetic responses, areas of possible porphyry-style alteration, intrusive bodies and potential mineralising structures.
Mr Locke said the company expects the data acquisition and subsequent processing and interpretation will take four weeks.
The Bell Valley target contains the eastern half of the Copper Hill Igneous Complex (CHIC), which locally hosts the Copper Hill deposit with a total resource of 87Mt @ 0.32g/t Au & 0.36% Cu comprising indicated resources of 47mt @ 0.39g/t Au & 0.4% Cu and inferred resources of 39mt @ 0.24g/t Au & 0.32% Cu, using a 0.2% copper cut-off grade1.
The company has identified the Bella Prospect; a “doughnut” shaped magnetic pattern considered characteristic of porphyry intrusion, present within the Bell Valley target. Bella, which has a diameter of approximately 500m, sits near the edge of the CHIC, in a juxtaposition to the Copper Hills Deposit.
The Belgravia Project covers an area of 80km2 and is located in the central part of the Molong Volcanic Belt (MVB), which forms as part of the East Lachlan province within the Lachlan Fold Belt, NSW. The East Lachlan region constitutes the largest porphyry province in Australia.
