LARGE COPPER-GOLD TARGET IDENTIFIED AT CERRO DE FIERRO, SOUTHERN PERU
Strong IP anomalies suggest potential for Manto-style IOCG target at least 1km long and 500m wide
AusQuest Limited (ASX: AQD) is pleased to advise that it has identified a significant ironoxide copper-gold (IOCG) target at the Cerro de Fierro Project , located ~40km from the coastal town of Chala in southern Peru, based on results from a recent successful geophysical survey.
Induced Polarisation (IP) Surveys conducted over the project have located strong chargeability anomalies coincident with a magnetic anomaly that was being tested as a potential IOCG target. Earlier geological mapping and sampling completed by the Company in 2016 had located extensive copper mineralisation proximal to the magnetic target, with numerous copper values in excess of 1,000ppm Cu and many samples returning values in excess of 1% Cu ( Figure 1 ).
Computer modelling of the IP and magnetic data has confirmed that the target is at least 1,000m long and 500m wide with relatively flat dips suggesting the potential for significant amounts of sulphide and magnetite mineralisation within permeable layers (volcaniclastics) in the volcanic sequence, a similar setting to the Candelaria copper deposit in Chile.

The Cerro de Fierro Project is one of three projects in Peru that were selected by the Company’s alliance partner, South32 (ASX: S32), as ‘exploration opportunities’ under the Strategic Alliance Agreement (SAA). South32 can elect to progress the Project to joint venture status once a drilling program has been agreed. Under the joint venture, South32 would spend US$4.0 million to earn a 70% interest in the project.
The Cerro de Fierro prospect was originally identified from the Company’s aeromagnetic data as a potential IOCG target, extending over an area several square kilometres in size. The prospect is located at the southern end of a recognised IOCG metallogenic belt within 150km of the Mina Justa (~475Mt @ 0.68% Cu) and Pampa de Pongo (945Mt @ 44.7% Fe, 0.12% Cu, 0.09 gt Au) deposits.

Geochemical data over the prospect identified a range of metal associations and metal patterns, suggesting that the buried magnetic target could be central to a large-scale redistribution of metals (Cu, Ag) within the volcanic sequence, reflecting the potential for IOCG (manto)-style mineralisation at depth.

The pole-dipole IP survey (200m dipoles, n=1 to 6, line spacing 400m) completed by Valdor SudAmerica, was designed to identify potential drill targets associated with the magnetic and geochemical anomalies.
Strong IP responses (chargeability >20mv/v) were detected on several lines coincident with the magnetic target, indicating the potential for buried mineralisation at depths ranging from ~150m to 300m and extending over a strike length of at least 1,000m. The relatively flat-lying nature of the IP target is compatible with the flat dips inferred for the volcanic (andesitic) sequence, suggesting that mineralisation may occur in layers (volcaniclastics) within the volcanic sequence ( Figure 2 ).
The IP anomalies are thought to reflect a combination of iron sulphide and iron oxide mineralisation with potential for copper oxide and/or sulphide mineralisation throughout the target section, which may be up to several hundred metres thick. The NNW trend of the target parallels mapped structures in the area, implying a possible relationship between structure, sulphides and the magnetic target.
AusQuest Managing Director Graeme Drew said the identification of a large-scale IPmagnetic target at the Cerro de Fierro IOCG Prospect was another highly significant development for the Company.
“This is the second strong drill target to be identified in Peru under our Strategic Alliance with South32,” he said.
“We are confident that we will be able to present the Cerro de Fierro Project to South32 as a drill-ready target under our Strategic Alliance Agreement,” he said. “In the meantime, survey work is continuing at the Alliance’s other prospects both in Peru and Australia and we remain confident that further drilling opportunities will be forthcoming in the not too distant future.”
