VANCOUVER, British Columbia — November 6, 2025 — Leads & Copy — Tower Resources Ltd. (TSXV: TWR) has started a 3000-meter diamond drilling program to expand its high-grade Thunder North and Blue Sky gold discoveries on its Rabbit North property in the Kamloops porphyry Cu mining district.

The drilling program will consist of about 12 holes focused on the Thunder North and Blue Sky zones. The objective is to extend these zones east from mineralized intersections found in the latest drilling program in May 2025.

The most easterly holes on the zones showed:

• 19.0 meters of 4.93 g/t Au in Hole RN-25-062 at Thunder North
• 6.02 meters of 23.63 g/t Au in Hole RN-25-060 at Blue Sky

Previous holes at Thunder North and Blue Sky intersected gold zones at depths less than 150 meters, so the current drilling will test the continuity of mineralization down to 300 meters. A few holes at Blue Sky will target the north-south trending contact between the Nicola volcanics and Durand diorite, instead of the main ENE gold trend, to assess the mineralization extent of this contact.

If the drilling campaign proves successful, Tower Resources expects to expand the program to 5000 meters. Selection and approval processes are underway for potential drill sites up to 800 meters east of the Blue Sky zone. These sites will allow preliminary testing of gold grain anomalies identified in the company’s October till heavy mineral survey.
