Polymetals Resources (ASX: POL) announces that the recently completed 500 line-kilometre airborne magnetic survey has identified 8 targets within the company’s wholly owned Mansala Gold Project in Guinea, West Africa.
Polymetals Resources reports the airborne magnetic survey was conducted by AeroPhysX in June 2022 on 100m-line spacings. The objective of the about 500-line km survey was to provide detailed data to determine the structural controls of mineralisation and information on the nature and disposition of host rocks currently obscured by lateritic cover.
The geophysical data has been processed and an initial geological interpretation and target generation program has been carried out with 8 ‘high order’ geophysical targets identified.
Images of processed aeromagnetic data show NW – NNW and NE – NNE magnetic lineaments pattern, as well as lithological and structural features that may have controlled the localisation of the known gold mineralisation.
Another key structural feature identified is the intense folding with axial planes along NNW and NNE directions that may influence mineralisation.
Commenting on the results, Polymetals Project Manager William Pountney said: “We are excited about the outcome of the magnetic survey and the structural features associated with the very prospective Area F at the Mansala Gold Project.
“We are excited about the outcome of the magnetic survey”
The high-grade pit sampling trend defined as Area F, identified within previous campaigns, is coincident with an interpreted felsic intrusive (Cupola), faults and folded units. These structural features are known criteria for large Siguiri style gold deposits within the region and provide the Company with additional confidence in targets for our next drill program.
In addition to identifying prospective gold zones within the Mansala tenement, the survey has provided the Company with additional vectors to explore for new targets within the licence. The team looks forward to both a productive field season and commencing Mansala’s first AC/RC drill program.”
The company reports 2 high-priority geophysical targets identified from the airborne magnetic survey at Mansala intersect the known NNE trend of strongly anomalous gold found in artisanal pit sampling in the NE quadrant of the permit (Area F).
This makes Area F a highly prospective location to drill test in the coming field season. Targets 1 and 2 encompass all relevant mineralisation criteria for a large mineralising system and could be related to a Siguiri-style gold deposit.
These targets comprise folds, faults, are proximal to a shear zone, felsic intrusive and structural lineaments that compare well with known deposits in the Siguiri Basin.
The company notes during the wet season compilation and further refinement of interpretation of all currently available data will be undertaken.
Drilling programs for both Alahiné and Mansala tenements will be planned.
