Tower's Till Gold Grain Survey Expands the Rabbit North Gold System 1000 m Eastward Across the Durand Stock, More Than Doubling its Footprint to 1.5 km2, and Yields an Exceptional 1001-Grain Anomaly 800 m Along Strike from the High-Grade Blue-Sky Zone
Tower (OTC: TWRFF) reported results from a 66-sample till survey on November 3, 2025 that expand the Rabbit North gold system ~1000 m east across the Durand Stock and more than double its footprint to 1.5 km2. The survey returned up to 1001 gold grains (Sample 342) and another peak of 560 grains; 45% of samples exceeded 100 grains versus a background of 5 grains. The strongest 1001-grain anomaly lies ~800 m ENE of Hole RN-25-060, which intersected 6.02 m of 23.63 g/t Au. Three discrete gold dispersal trains (Nos. 303, 342, 347) were identified, the results support nearby, minimally transported sources and will guide an expanded diamond-drilling program focused on Blue Sky and Thunder North.
Tower (OTC: TWRFF) ha riportato i risultati da un sondaggio di till su 66 campioni il 3 novembre 2025 che espandono il sistema d'oro Rabbit North circa 1000 m a est attraverso la Durand Stock e più che raddoppiano l'area a 1,5 km2. Il sondaggio ha restituito fino a 1001 chicchi d'oro (campione 342) e un altro picco di 560 chicchi; il 45% dei campioni ha superato i 100 chicchi contro una base di 5 chicchi. L'anomalia più forte di 1001 chicchi si trova a ~800 m ENE del Pozzo RN-25-060, che intersecò 6,02 m di 23,63 g/t Au.

- Footprint doubled to 1.5 km2
- 1001 gold grains — strongest anomaly at Rabbit North
- 6.02 m @ 23.63 g/t Au in Hole RN-25-060 confirms high-grade nearby
- Three dispersal trains (303, 342, 347) identified for focused drilling
- Large area now requires intensive drilling and increased exploration spend
- Till anomalies require drilling to confirm bedrock source and continuity
Vancouver, British Columbia--(Newsfile Corp. - November 3, 2025) - Tower Resources Ltd. (TSXV: TWR) ("Tower" or the "Company") is pleased to report that all gold grain results have been received from the 66-sample till survey completed three weeks ago on the Durand Stock to guide hole placement in the Company's diamond drilling programs on the Rabbit North property in the heart of the Kamloops porphyry Cu mining district (see Figs. 1 and 2 and Table 1 at end of press release).
Every till sample was significantly anomalous in gold grains (see Fig. 3 below), expanding the Rabbit North gold system eastward 1000 m across the Durand Stock and more than doubling its footprint to 1.5 km2 while leaving it open to further expansion.
Importantly, the strongest anomalies, 560 and 1001 gold grains, are strategically located ~150 and 800 m east-northeast along strike from the Company's easternmost and highest-grade drill intersection, 6.02 m of 23.63 g/t Au in Hole RN-24-060 on the edge of the Durand Stock (see July 10, 2025 press release) on the emerging Blue Sky gold trend. The 1001-grain anomaly is the strongest obtained to date at Rabbit North and the gold grains are still pristine (see Fig. 4 below), indicating that their source is nearby.
The till 1000 m east of the Thunder, Thunder North and Lightning zones is also strongly anomalous, indicating that the structural corridor containing these volcanic-hosted gold zones also extends eastward through the Durand Stock.

Overall Distribution of Gold Grains
The 66 new till samples, including two duplicates, were of the same weight (~10 kg) and numbered in sequence with the 289 samples that Tower collected in 2021-2022. The samples yielded from 21 to 1001 gold grains with
Three New Gold Dispersal Trains Identified
Most of the gold in Tower's Lightning, Thunder and Blue Sky zones at Rabbit North occurs as fine inclusions in pyrite rather visible gold grains. Where the exposed host rock was fresh when glaciated, this fine gold was only partially liberated into the till. Where the exposures were lateritized, the gold had already been liberated by oxidation of the pyrite and degradation of the rock to clay. Consequently, gold grain dispersal trains like the Dominic Lake Train down-ice from the low-grade (~1.5 g/t) but lateritized Lightning Zone tend to be stronger and longer (>1000 m vs. <500 m) than those like the Central Train from the high-grade but unoxidized Thunder North zone.
A gold grain dispersal train as large and persistent as the one over the Durand Stock would be expected to have multiple sources, and three sub-trains suggestive of discrete, wide and/or high-grade gold sources are discernible within it (see Fig. 3). These trains have been numbered 303, 342 and 347 - the numbers of the most anomalous till samples within them (see Fig. 2 and Table 1). All three are presumed to be of the Central Train type - i.e. sourced from unoxidized, potentially high-grade gold zones - due to their relative shortness and the resistant nature of the Durand diorite which forms a prominent ridge (see Fig. 2) above the less resistant Nicola volcanics.
The heads (i.e. origins) of two of the trains, Nos. 342 and 347, are along the northeastward projection of the high-grade Blue Sky trend through the Durand Stock toward historical percussion drill hole No. 1990-05 (see Fig. 2), which intersected 39.7 m vertically of 1.75 g/t Au. However, the till is still significantly anomalous for 200 m up-ice from the heads of the trains, indicating the presence of another, parallel gold trend to the north, and Hole 1990-05 appears to have intersected this trend (see Fig. 3) rather than the Blue Sky trend. Both gold trends appear to extend westward from the stock into the Nicola volcanics beyond the area covered by the till survey.
Train 342 peaks at 1001 gold grains ~800 m east-northeast of the Company's easternmost and highest -grade intersection of the Blue Sky zone, 6.02 m of 23.63 g/t Au in Durand diorite in Hole RN-25-060 on the western edge of the stock (see Fig. 3). Most of the gold grains are still physically pristine (see Fig. 4 and Table 1) indicating that they have undergone negligible glacial transport and thus that their source is probably within 100 m up-ice (i.e. to the northwest) on the Blue Sky trend. By comparison, the highest gold counts obtained from the Central and Dominic Lake Trains were 452 and 785 grains, respectively. The train remains strong 200 m down-ice where Sample 333 yielded 405 grains. Sample 343, collected 100 m west of Sample 342, yielded only 154 grains but Sample 344 collected 200 m to the west yielded 363 grains.
Train 347 peaks at 560 gold grains ~150 m east-northeast of the high-grade Hole 060 intersection. The next sample 100 m further along the Blue Sky trend, No. 348, yielded 292 grains. Together these results imply that the newly discovered Blue Sky zone continues uninterrupted from the Nicola volcanics into the Durand Stock for at least 300 metres.
The two till samples collected between the heads of Trains 342 and 347 were only weakly anomalous in gold grains despite being close to the Blue Sky trend. However, this gold dispersal "gap" is due to a patch of Chilcotin basalt lava flows (see Fig. 3) that covers at least 100 m of the Blue Sky trend and protected it from glaciation.
The third gold dispersal train, Train 303, is in the southern part of the Durand Stock ~1000 m east of the Lightning Zone, suggesting that the structural corridor that contains Tower's volcanic-hosted Thunder, Thunder North and Lightning zones extends eastward through the stock and has significantly mineralized the diorite, at least locally. Sample 303, at the head of the train, yielded 390 gold grains, most of which are still pristine or only slightly deformed (see Table 1). The train remains strong 200 m down-ice at the limit of sampling where Sample 291 yielded 214 gold grains and a nearby till sample from Tower's initial 2021 reconnaissance survey yielded 236 grains (see Fig. 3).
Next Steps
By more than doubling the footprint of the Rabbit North gold system and confirming the initial evidence from Hole 060 at Blue Sky that the Durand diorite is a hospitable gold host, the till sampling program has opened up a very large area requiring intensive drilling.
While the initial focus of the pending drilling program will be on sites near the promising Blue Sky and Thunder North zones for which the required notice of drilling has been given, the drill program may be expanded to test the heads of the three strong gold grain dispersal trains identified in the till survey.
Methods
Overburden Drilling Management Ltd. (ODM) collected the till samples and processed them at the company's heavy indicator mineral laboratory in Ottawa, Ontario.
The samples were collected by a three-person team led by David Hozjan, MSc., P.Geo. At each sample site, a pit was excavated by hand into the C-horizon of the post-glacial soil profile, typically to a depth of 0.5-0.8 m, to reach minimally oxidized, structurally compact till, the subglacially deposited variety that is required for an effective survey.
The till from each pit was sieved at 8 mm to remove most of the clasts and obtain approximately 12 kg of -8 mm material which, after finer screening at 2 mm in the laboratory, typically yields approximately 10 kg of fine sandy silt, the particle size fraction in which most gold grains reside. The clasts were examined to determine their lithologies and checked for possible archeological artefacts. The pit and surroundings were photographed both before and after the pit was filled in and the ground was restored to its original level.
At two sites, a duplicate sample was collected by screening to obtain approximately 24 kg of -8 mm material and splitting this in small, alternating scoopfuls on site to obtain two equal 12 kg samples. The samples were shipped in sealed containers to ODM's laboratory by a commercial trucking company.
Prior to extracting the heavy mineral fraction from the samples in its laboratory, ODM removed a representative 500 g split and further sieved it at 0.063 mm to separate the fine silt + clay fraction. This fraction is being analyzed geochemically in Kamloops by Actlabs Ltd., a laboratory certified as ISO/IEC 17025 Accredited (Lab 790) by the Standards Council of Canada. When submitting the samples to Actlabs, ODM included several splits of a blind (i.e. visually indistinguishable) quality assurance sample from a natural till section that contains consistently elevated levels of Au, Cu, Mo and other key elements.
Heavy mineral concentration was effected by ODM on the bulk of each sample using a shaking table modified to recover the fine, silt-sized gold particles that normally comprise
