Key highlights

Noronex completed its Acquisition of a 100% interest in the Sleitat Tin-Tungsten-Silver Project in Alaska.
Mapping extended the northern greisen system to more than 1 km of strike, beyond historic drilling.
Assays from 150 rock samples are expected in November 2026.

Noronex Limited (ASX:NRX) announced on 6 October 2026 that it has completed its maiden field exploration program and high-resolution geophysical survey at the Sleitat Tin-Tungsten-Silver Project in Alaska, USA. The company also reported that it has completed the acquisition of a 100% interest in the project.

Field program results

Surface mapping in September 2026 extended the mapped strike of the northern greisen system to more than 1 km, which the company says is substantially beyond the area tested by historic drilling. A total of 150 rock samples were collected and submitted for assays, metallurgical testing and ore sorting, with assay results expected in November 2026.

Geophysical survey

About 250 line-kilometres of magnetics and radiometrics were flown at 50 m line spacing, compared with roughly one-mile spacing in historical government surveys. Initial data has been received and interpretation is expected during October 2026 to assist drill targeting and identify possible extensions beyond the roughly 1,400 m of shallow historical drilling.

Planning for drilling

The company plans to review historical drill core held at a government Facility in Anchorage and to integrate the datasets into a three-dimensional geological interpretation. The results are intended to support a JORC Exploration Target and planning for a maiden drilling program, with drill permitting activities expected to start shortly. Noronex also appointed Alaskan geologist Joe Piekenbrock, who was involved in the original discovery of Sleitat, to its Advisory Board.

About the Sleitat program

The program is described as the first systematic modern exploration of the broader mineralised system at Sleitat. Alongside mapping and geophysics, the 150 rock samples will be used for assays, metallurgical testing and ore sorting. The company intends to combine these results with the historical drilling and core review to assess possible extensions to known mineralisation, and it expects to work toward an updated JORC Exploration Target for the project.

Risks shareholders may weigh

The announcement reports mapping and geophysics but no new assay results, and historical drilling was shallow. The project has no JORC resource reported in the announcement, and an Exploration Target remains to be defined. Assay and interpretation timing may change.

Other factors include Alaskan permitting and seasonal access, tin and tungsten prices, funding for drilling and general exploration risk.

What's next

Noronex expects geophysical interpretation in October 2026 and surface sampling assays in November 2026. These datasets, alongside the historical core review, will feed into an updated JORC Exploration Target and drill targeting for the maiden program.
