Vancouver, British Columbia--(Newsfile Corp. - December 18, 2025) - Tower Resources Ltd. (TSXV: TWR) (" Tower " or the " Company ") is pleased to report that it has successfully completed its expanded diamond drilling program on the high-grade Blue Sky gold trend and Thunder North gold zone (see Fig. 1) on its Rabbit North property in the heart of the Kamloops porphyry Cu mining district (see index map of Fig. 1).

Due to high drilling productivity, the program was expanded from 3000 m to 3213 m before drilling was suspended for the holiday season. Drilling is expected to resume in February as the daylight hours increase.

Blue Sky Drilling

Six holes totaling 1756 m, Nos. RN25-063 to 068, were drilled on the Blue Sky trend (see Table 1). The first three holes were drilled at various angles near discovery hole No. RN24-055 ( 31.5 m of 4.15 g/t Au; see Fig. 1) to determine the orientation and overall prospectivity of the contact between the Durand diorite and Nicola tuff along which the Hole 055 mineralization occurs. The other three holes were designed to follow the Durand-hosted Hole 060 intersection ( 6.02 m of 23.63 g/t Au; see Fig. 1) both down-dip and 100 m eastward along the mineralized trend toward the strong, 560-grain anomaly obtained from the Company's recent till gold grain survey (see Fig. 2 and November 3, 2025 press release ).

Thunder North Drilling

Five holes totaling 1457 m, Nos. RN25-069 to 073, were drilled at Thunder North (see Table 1). One hole was drilled west of the known mineralization to verify previous indications, from Hole RN24-054, that Thunder North is faulted to the south and continues westward as the Thunder Zone (formerly Thunder South) which was intersected in Hole RN23-041 in 2023 ( 13.3 m of 3.28 g/t Au followed 10 m down-hole by 10.1 m of 2.16 g/t Au; see Fig. 1 and April 5, 2023 press release ) and on which the Company has not yet performed any follow-up drilling. The other four holes were variously designed to extend the Thunder North zone eastward from Hole RN25-062 ( 19.0 m of 4.93 g/t Au; see Fig. 1) or confirm continuity of the gold mineralization to depths >150 m and fill in a gap left by the intersection of a cross-cutting, post-mineralization dyke in Hole RN23-040 (see Fig. 1).

Assay Schedule

Tower's previous drilling campaigns have shown that most of the drill core is significantly anomalous in Au, reflecting the large scale and pervasiveness of the previously unknown gold mineralizing system that the Company has discovered at Rabbit North and differs in both age (younger) and style (orogenic) from the typical Late Triassic porphyry Cu±Au deposits of the Kamloops District. Consequently, all core except that from the post-mineralization Chilcotin basalt cover flows must be analyzed, typically in 1 to 2 m intervals yielding an average of 200 samples per hole. Nevertheless, the Company expects to receive most of the assays prior to the planned resumption of drilling in February.
