Before the airborne survey, Hannan's exploration team had identified at least 12 intrusion related porphyry/epithermal/skarn target areas, which correlate with porphyry indicator minerals from stream sediment samples (BLEG) and/or hydrothermally altered boulders in catchments across the 94,500 ha property. This is considered by Hannan to be an exceptional number of copper-gold targets discovered in a new Miocene belt at such an early stage of exploration, none which have ever been drill tested.
Highlights:
A 5,176-line kilometre airborne magnetic and radiometric survey has been completed and processed at the Valiente project. The survey covers the entire 94,500 ha of Hannan's 100%-owned mining concessions across the project area.
Hannan's preliminary evaluation of the airborne data demonstrates at least 18 magnetic anomalies of significance across the project.
Magnetic and radiometric data were recorded simultaneously during the survey. Both data sets are instrumental for targeting porphyry deposits due to the presence of magnetic minerals (such as magnetite) and potassic alteration (from minerals such as biotite and K-feldspar), often associated with the core of porphyry mineral systems.
A strong correlation is observed with known mineralized areas and magnetic and potassic radiometric anomalies such as at:

DISCUSSION
The 100% owned and explored by
The Valiente project is believed to consist of an overlapping suit of porphyry targets with composition ranging from conventional calc-alkalic to alkalic hosted Cu-Au mineralization (reported here). It is anticipated that both high and low-magnetic and radiometric correlations may exist within the property and a detailed evaluation combing the airborne data with 3D litho-structural interpretations and results from stream sediments samples (BLEG) is currently being undertaken.
The initial results presented demonstrate an excellent correlation between the known areas of mineralization and magnetic and radiometric data. This positive correlation is thought to be augmented by two local factors. Firstly, the sedimentary country rocks are non-magnetic which make detection of low magnetic bodies simpler. Secondly, the overburden of the area is local and despite the thick jungle canopy, the detection of potassic alteration zones from radiometric data is straight forward.
