Anson Resources Ltd (ASX:ASN) (FRA:9MY) has increased the nickel-copper-PGE prospectivity of The Bull Project near Chalice Mining Ltd’s (ASX:CHN) Julimar discovery north of Perth in Western Australia after completing a 3D Aeromagnetic Inversion Model.
The company is encouraged by the positive indications from the 3D Model, particularly as the geometry is considered favourable for hosting large-scale magmatic deposits.
Similar irregular intrusive bodies are known to host significant nickel-copper+/-PGE sulphide deposits globally, such as the Kabanga Deposit in Tanzania and Jinchuan Deposit in China.
The 3D Aeromagnetic Inversion Model was created using the data obtained from a Drone Magnetic Survey.
“Exciting exploration opportunity”
Anson’s executive chairman and CEO Bruce Richardson said: “The Bull Project continues to reveal itself as an extremely exciting exploration opportunity for Anson and we are encouraged by the data generated from the drone magnetic survey and subsequent 3D aeromagnetic inversion model.
“Importantly, these programs have highlighted the potential structure and domaining within the intrusive and defined the geometry in three dimensions.
“Anson’s technical team continues to build its geological understanding of The Bull Project and remains buoyed by the considerable similarities the project shares with Chalice’s world-class Julimar nickel-copper-PGE deposit located only 20 kilometres north of our tenure.”
Processing inversion model
Anson hired independent geophysical consultants to process the recently flown magnetic data and an inversion model of the 50 metres line spacing aeromagnetic data from the drone survey was created to define the geometry of the intrusive body in three dimensions.
The intrusive at The Bull is modelled as an approximately 1,400 metres long x 500 metres wide x 500 metres deep chonolith body.
Fixed Loop Electromagnetic survey
The company is now planning to conduct a Fixed Loop Electromagnetic (FLEM) survey over the Target 1 bullseye anomaly at The Bull Project.
Independent geophysical consultants have designed a survey to completely cover the magnetic model.
The survey aims to identify bedrock conductors within the anomaly which may represent massive sulphide accumulation and these conductors will form a key component of future drilling programs at The Bull.
Richardson said: “Follow-up work programs are currently being finalised for Q3 2021 and we look forward to providing further updates on progress from across our portfolio over the coming weeks.”
