Chilwa Minerals Limited (ASX: CHW) has completed an extensive aeromagnetic and radiometric Survey over its entire 708km2 Chilwa Critical Minerals Project.
The Lake Chilwa area is described as an endorheic basin, which occurs where the river system is completed isolated from the ocean. With other mapped carbonatites within and surrounding the Chilwa Project, the company believes there is value in exploring for the discovery of both primary and secondary clay hosted rare earth elements mineralization within the project area. The company will commence diamond drilling once the results of this programme are received to focus in on high priority areas.
Chilwa’s managing director, Cadell Buss, commented: “Whilst we are firmly focused on the current drilling programme, the initial field results are an interesting surprise and it makes sense for the company to broaden its exploration programme, particularly in the clays that underly the mineral sands horizon. With this new information, the company decided to complete a project wide aeromag and radiometric survey, rather than over just the extension area as originally communicated in the prospectus, to detect high-priority targets that we will look to follow up with further exploration activities.
The Lake Chilwa area contains a number of carbonatites, which are known source rocks for rare earth mineralization. The aeromag survey results will be used to better define the carbonatites within the project area for follow up assessment. The company anticipates the modelled and interpreted survey data to be available in mid-July and diamond drilling will commence following a review of the aeromag data for improved targeting.
