Polymetals Resources Ltd (ASX:POL) has identified eight high-priority geophysical targets during a recently completed aeromagnetic survey at its Mansala Gold Project in Guinea.
The objective of the 500-line kilometre 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 a lateritic cover.
Encouragingly, the structural features identified during the survey are comparable with the large Siguiri-style mineralised systems in the region, providing the company with “additional confidence” for its next drill program.
Moving forward, Polymetals will use the newly identified mineralisation controls to refine its model for gold discovery.
“Very prospective area”
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.
“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.”
High-priority geophysical targets
Two 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).
Notably, this makes Area F a highly prospective location to drill test in the coming field season.
Targets, T1 and T2 encompass all relevant mineralisation criteria for a large mineralising system and could be related to a Siguiri-style gold deposit.
These targets comprise folds and faults that are proximal to a shear zone, and felsic intrusive and structural lineaments that compare well with known deposits in the Siguiri Basin.
Forward plan
During the wet season, Polymetals will plan for the next field season by compiling and refining its interpretation of all currently available data.
In addition, the company aims to start the planning process for drill programs for the Alahiné and Mansala tenements.
For all bottom-of-hole samples collected during previous auger drilling programs and recent soil samples collected on the Mansala licence trace element abundances including pathfinder elements such as arsenic, silver, antimony, molybdenum, chromium, tellurium and tungsten will be measured by a portable X-ray Fluorescence (pXRF) analyser.
Furthermore, anomalous abundances of some or all of these elements may signal the presence of mineralisation at depth, in which case, further follow-up will be undertaken.
