Lion One Metals finishes CSAMT survey at Tuvatu Alkaline Gold Project, Fiji

Gold explorer Lion One Metals (ASX:LLO) has completed a controlled-source audio-frequency magnetotellurics (CSAMT) survey at its wholly owned Tuvatu Alkaline Gold Project in Fiji.

The company reports the 2022-2023 CSAMT survey was designed to complement a 2019 survey by adding infill and extensional lines to the previous survey area.

The 2019 survey was ‘moderate to widely spaced’, with line spacing ranging from 300m to 800m and station spacing every 100m. Lion One reports line and station spacing has improved ‘significantly’ across the Navilawa Caldera following the 2022-2023 CSAMT survey, with line spacing now ranging from 100m to 400m and station spacing only 50m apart on all new lines.

The company says the increased line and station density will provide greater resolution across the property and will assist in refining and generating new drill targets in the caldera.

Lion One reports the 2022-2023 CSAMT survey was completed by Adelaide-based Zonge Engineering and Research Organization, surveying a total of 33 line-km. 

The 2022-2023 survey included 5 survey lines oriented north-south across the main Tuvatu deposit, providing a ‘high-density’ grid of coverage across the area. The company says this will provide ‘high-quality’ resistivity data for the Tuvatu deposit and all near-mine exploration targets, such as the West Zone.

Additionally, Lion One reports it has identified numerous regional prospects throughout the Navilawa Caldera, with multiple surface samples returning grades over 100g/t Au. 

A goal of the 2022-2023 CSAMT survey was to improve the coverage and understanding of the structural architecture underlying these prospects, some of which are located on the edge of the 2019 survey lines where results can be less reliable.

Commenting on the CSAMT survey, Lion One Metals Chief Executive Officer (CEO) and Chairman Walter Berukoff says: “We’re thrilled to have completed our CSAMT survey, and we eagerly await the results of the survey, which we hope to have available later in July.

The 2019 survey was invaluable in helping to discover the feeder zone underlying Tuvatu and led us directly to the 500 Zone, where we intersected 75.9m of 20.86g/t Au. The 2022-2023 survey will complement the 2019 survey and will dramatically improve survey resolution across the property, where we have already identified numerous exciting and untested prospects.

The CSAMT data will help us to identify and refine drill targets underlying those prospects, and we look forward to drill testing select targets later in 2023″

CSAMT is a ground geophysical method used for obtaining information about subsurface resistivity in a survey area. The company says it measures the electrical resistivity of rocks down to depths of about 1.2km to 1.5km, which it claims is much deeper than alternative resistivity techniques.

Lion One Metals is an ASX-listed gold explorer focused on its Tuvatu Alkaline Gold Project on the island of Viti Levu in Fiji.
