Anson Resources Ltd’s (ASX:ASN) geological mapping and geochemical sampling program has confirmed the geophysical interpretation of an intrusive complex at the company’s 100%-owned The Bull Project in Western Australia.
Confirmation of the mafic-ultramafic intrusive complex following mapping across the Target 1 anomaly determines that The Bull bears similar geological terrane to Chalice Mining Ltd’s (ASX:CHN) Julimar nickel-copper-platinum group element (PGE) discovery.
The Bull is modelled as a 1,400-metre-long, 500-metre-wide and 500-metre-deep chonolith body, with favourable geometry for hosting large-scale magmatic sulphide deposits.
“Pleased with results from mapping”
Anson executive chairman and CEO Bruce Richardson said: “We are very pleased that results from the geological mapping and rock chip sampling closely align with the recently completed 3D modelling of the Target 1 anomaly.
“Although there is still plenty of work to be done, the early similarities between what we are seeing at The Bull and the early results achieved by Chalice on the pathway to discovering Julimar are encouraging.
“We continue to build our knowledge and geological understanding of The Bull as we move quickly towards defining a set of targets for our maiden drilling program later this year.”
Mapping and sampling program
Recently, Anson set out to map and sample The Bull’s Target 1 anomaly in order to “ground truth” its mafic-ultramafic intrusive interpretation.
During exploration, the ASX-lister discovered mafic and ultramafics samples within the area interpreted in the 3D model.
The survey also revealed that even though they were historically mapped as migmatites and granites, the magnetic anomalies identified may form part of a mafic-ultramafic intrusive system, similar to Chalice’s world-class Julimar nickel-copper-PGE deposit, which lies just 20 kilometres north of The Bull.
This means Anson has reason to believe the Target 1 anomaly is part of a larger prospective mafic/ultramafic intrusive complex.
To date, the company has collected 89 rock chip samples from Target 1, with geochemical samples confirming anomalous mineralisation.
Anomalous values were recorded for nickel, copper, palladium and lead, with a maximum of 20 parts per billion palladium and 25 parts per billion lead.
Rock chip samples were collected from outcrop and sub-crop geology from topographic highs, while other areas within the tenement were comprised of paddocks with little to no outcrop, although float and sub-crop were observed and sampled from easily accessible areas.
Visible sulphides were also noted in a sample collected from the area on the western edge of the 3D model.
Following the mapping and sampling program, fixed loop electromagnetic (FLEM) surveying is underway to identify EM bedrock conductor plates, which could be the response to massive sulphide mineralisation.
