Tower infills gaps between gold zones at Rabbit North

Vancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Tower Resources Ltd. (TSXV: TWR) (" Tower " or the " Company ") is pleased to report that drilling is progressing well and continuing to intersect wide pyritized zones typical of the Company's orogenic gold discoveries on the Rabbit North property near Kamloops, B.C. (see Fig. 1). Thunder North - Blue Sky Gap As previously announced ( see June 3, 2026 press release ), the main objective of the present 2000 to 3000 m drilling program is to infill, at 50 m spacing, the eastern half of the remaining 400-m-long untested gap between the promising Thunder North and Blue Sky gold zones. The gap area is underlain by Nicola volcaniclastic rocks, and the Thunder - Blue Sky gold trend, which is characterized by shear deformation and quartz-feldspar porphyry (QFP) dyke injection accompanied by hydrothermal bleaching and quartz-sericite-pyrite (QSP) alteration, appears to more coherent in the current drill holes (see Fig. 2) than in the Blue Sky discovery area to the east where the volcanic rocks are intruded by the dioritic Durand Stock (see Fig. 1).

These shear zones are roughly coincident with more recent graben fault valleys that have been infilled by Chilcotin basalt flows. The yellow stars mark the locations of the main Au intersections in the initial discovery holes on the gold zones.

Areas targeted in the current drill program are highlighted.

The planned extension of December's unfinished Hole 073 to obtain a deeper intersection of Thunder North was reconsidered because the drill could not re-enter the hole. A replacement hole has been added 50 m to the east.
