Rackla Metals (TSX-V:RAK) has begun a helicopter-borne magnetic and radiometric survey across its 155km² Lentung Tungsten Project in the Northwest Territories, Canada.
Precision GeoSurveys is flying the program, extending coverage beyond a drone-based magnetic survey completed over the main mineralised zones in July.
Rackla says the pilot survey showed a correlation between magnetic highs and known tungsten mineralisation, likely reflecting pyrrhotite and other magnetic minerals in the skarn system.
It also identified previously unrecognised anomalies between the Emma-Western Skarn-Stephen’s Ridge and Far West anomalies, including two that the company describes as significant in size.
Linear features trending northwest–southeast and north–south indicate structural controls on mineralisation, according to Rackla.
CEO Simon Ridgway says the new program is Lentung’s first property-wide airborne geophysical survey.
“Given the success of the pilot survey in identifying the mineralised zones Union Carbide discovered by drilling, I am keen to see the results of the first property-wide airborne geophysical survey ever completed at Lentung,” Ridgway says.
“Deploying modern multi-sensor geophysics over both the Lentung tungsten prospects and the adjoining South Lened Rare Earths target will help our geological team unravel the complex structural and igneous architecture of our flagship property — and has the potential to lead us directly to new mineralised zones.”
Drilling is continuing alongside the survey. Rackla has completed more than 2,000m of diamond drilling across 20 holes and 277m of reverse circulation drilling across five holes, with assays pending.
The company says it plans to complete 10,000m during the 2026 field season, weather permitting. Initial results are expected within two weeks.
Rackla recently announced a placement to support drilling and exploration at Lentung. The wholly owned project lies 120km south of Mactung and 55km north of the former Cantung mine. Historical exploration identified 15 tungsten-bearing zones along 15km of strike.
Rackla Metals is a Vancouver-based tungsten and rare earths explorer advancing Lentung and the neighbouring South Lened target in the Northwest Territories.
