Noronex has completed its Sleitat tin project acquisition and expanded the mapped Alaskan greisen system beyond one kilometre, but the explorer ended September with A$1.135 million and only 1.28 quarters of estimated funding. Assay results, South32-backed drilling and a potential capital raise now sit alongside the company’s exploration ambitions.
- Sleitat acquisition completed with more than 1km of mapped northern greisen
- 150 rock samples collected, with assays expected in November 2026
- Alteration response extends locally to approximately 200m around mapped greisen
- South32-supported 2,500m-3,000m drill program due to start in December
- A$1.135m cash balance and 1.28 quarters of estimated funding remaining
Sleitat acquisition moves into target generation
Noronex Limited (ASX:NRX) has finished the acquisition of the Sleitat Tin-Tungsten-Silver Project in Alaska, turning the company’s recent US expansion into an active exploration program. Mapping during the September quarter traced the northern greisen system over more than one kilometre of strike, including ground beyond the area tested by historical drilling.
The result extends the field evidence around a project that carries a substantial but non-JORC historical estimate of 25.9 million tonnes grading up to 0.37% tin, 0.04% tungsten and 17 grams per tonne silver. Historical drilling included a 29.1-metre interval at 1.56% tin and 28 grams per tonne silver, including 3.1 metres at 12.55% tin. Those figures remain historical estimates and intercepts: Noronex cautions they have not been classified under JORC 2012 and may not convert into a current Mineral Resource or Ore Reserve.
The acquisition completes the transaction reported in the Sleitat option exercise, while the exploration work advances the modern program that had been launched in September. Noronex collected 150 rock samples across the project, including from the known greisen and newly mapped areas, with assay results expected in November. The company is using those results to assess the distribution of tin, tungsten and silver and select targets for potential drilling.
Geophysics points to a larger alteration system
A high-resolution airborne magnetic, radiometric and VLF-EM survey has added a second layer to the field observations. Radiometric imagery identified alteration locally up to approximately 200 metres wide around the mapped greisen, while magnetic and radiometric interpretation suggests the granite and alteration system may continue beneath adjacent cover.
That is encouraging for target generation, but it is not evidence of continuous mineralisation. Noronex expressly says the geophysical features do not establish tin mineralisation beneath cover. The company is combining the survey with surface sampling, historical drilling and a three-dimensional geological interpretation before preparing a JORC Exploration Target and prioritising a maiden drilling program for the 2027 field season.
South32 program keeps African portfolio active
While Alaska becomes the headline project, Noronex’s Kalahari Copper Belt portfolio remains the company’s main near-term fieldwork engine. South32 continues to support exploration across Noronex’s Namibian and Botswanan assets, with a 2,500-metre to 3,000-metre drill program scheduled to begin in December 2026.
At Botswana’s Cgae Cgae project, earlier reconnaissance drilling intersected copper anomalism and pathfinder elements but no economic mineralisation. The strongest result cited in the quarterly report was a 14-metre zone above 250 parts per million copper. Noronex says the result provides vectoring information for a potentially fertile undercover hydrothermal system, while ground gravity surveys have now been completed to help define further targets. Licence renewals and applications in Namibia remain at various approval stages, including the Rosy Copper application, which has received its environmental compliance certificate but still requires final ministerial endorsement.
Cash position leaves limited room for delay
The financial position is less expansive than the exploration map. Noronex ended the quarter with A$1.135 million in cash after A$890,000 of net operating outflows and A$497,000 spent on exploration and evaluation. On the company’s Appendix 5B calculation, that represents an estimated 1.28 quarters of funding at the current level of relevant outgoings, with no unused financing facilities reported.
Noronex says it expects to maintain operations through South32 funding, the ability to reduce exploration and overhead spending, and the capacity to raise capital under its ASX placement rules. The filing also records A$500,000 of South32 earn-in funding in financing cash flows and says the company expects to receive A$500,000 from South32 after quarter-end, a funding line that will matter if the December drilling schedule is to proceed without a fresh equity raise. James Thompson has taken over as chief executive, while Alaskan geologist Joe Piekenbrock has joined the advisory board after having been involved in Sleitat’s original discovery.
Bottom Line?
November Sleitat assays and the December South32 drilling program are the next tests of exploration momentum, but the 1.28-quarter cash estimate makes funding and spending discipline just as important as the geology.
Questions in the middle?
- Will the November assays support a JORC Exploration Target large enough to justify maiden drilling at Sleitat?
- Can South32 funding sustain the December African drill program while Noronex advances Alaska toward 2027 drilling?
- Will Noronex raise capital, cut expenditure, or rely on expected earn-in funding before its reported cash runway expires?
