Tower Hits High-Grade 23.63 g/t Gold over 6.02 m Near Surface in Hole 060 at Blue Sky, 70 m NE of Hole 055, Underscoring the Potential of the Durand Diorite to Host a Substantial Gold Deposit
Tower Hits High-Grade 23.63 g/t Gold over 6.02 m Near Surface in Hole 060 at Blue Sky, 70 m NE of
Hole 055, Underscoring the Potential of the Durand Diorite to Host a Substantial Gold Deposit
Vancouver, B.C. – July 10, 2025 - Tower Resources Ltd. (“Tower” or the “Company”) (TSXV: TWR) is
pleased to report the gold assays from the first two of four holes, Nos. RN-25-059 and 060, drilled in May
on the Company’s Rabbit North property in the heart of the Kamloops mining district (see Fig. 1). Hole
060, a 70 m step-out northeast into the Durand Diorite Stock (Fig. 2) from the diorite-hosted Blue Sky
gold discovery in Hole RN-24-055 on the western edge of the stock (31.5 m of 4.15 g/t Au; see December
23, 2024 news release), intersected an exceptional 23.63 g/t Au over 6.02 metres. Hole 059, drilled
above Hole 055, cut 7.6 m of 3.28 g/t Au and ended in mineralization grading 4.85 g/t Au.
Overview
The primary objective of the small May drilling campaign was to determine the strike and dip of the Blue
Sky gold trend to aid in siting holes for a much larger drilling program that the Company is currently
planning, especially longer, deeper holes given the great depth extent that is usual for such shear-hosted
gold mineralization and the apparent subvertical attitude of the zone. Both Holes 059 and 060
successfully intersected the Blue Sky zone, extending it 70 m along strike and 90 m upward to within 55
m of surface. The drilling further showed that gold zone strikes northeast, well into the Durand Diorite
toward the historical gold intersection in Hole 90-05 (40 m vertically @ 1.78 g/t Au), ~1 km further
northeast (see Fig. 2).
Figure 2 – “Horsetail” shear zone model for the Rabbit North gold system. See Table 2 for detailed Au
analyses.
Hole 060 Results
Hole 060 was drilled parallel to and 70 m east of discovery hole No. 055 but at a shallower dip (-45 versus
-60○) and, due to terrain conditions, oriented southeast rather than northwest. Except for a near-surface
slab of diorite-entrained volcanics, the core was entirely of Durand Diorite ‒ the gold host rock in the
discovery hole. In Hole 060, the 6.02 m interval from 84.14 m down-hole ‒ just 55 m from surface and
nearly 100 m higher than the ~150-m-deep discovery intersection in Hole 055 ‒ returned an exceptional
23.63 g/t Au including 1.95 m of 51.30 g/t Au (see Table 1). Like the discovery hole, Hole 060 intersected
six additional gold zones ranging from 1.82 m of 1.78 g/t Au to 7.12 m of 1.49 g/t Au (see Table 2).
Importantly from a mineral resource perspective, four of these zones occur within a 22.5 m interval
from 44.5 m down-hole, and thus above the high-grade gold zone, that averages 1.0 g/t Au.

Table 1 - Breakdown of Au analyses from the Blue Sky zone in Hole 060.
Although the Blue Sky gold intersection in Hole 060 is of a much higher grade than the similarly diorite-
hosted intersection in Hole 055, it is not as strongly altered (pyritized). This may be due to the presence
of excess magnetite in the Hole 060 diorite as magnetite is an efficient scavenger of gold from
hydrothermal fluids. As in Hole 055, the Au is accompanied by minor Cu (0.1-0.2%), possibly stripped from
the older, widespread porphyry Cu-Au mineralization that was introduced during emplacement of the
Durand Diorite.
Hole 059 Results
Hole 059 was collared forward of and in line with (i.e. above) Hole 055 and drilled at a shallower -45○ dip
with the intent of intersecting, closer to surface, the diorite-volcanic contact that constrains the Blue Sky
zone in Hole 055. It overshot the contact and entered the volcanics directly, indicating that the contact
passes between the two holes and dips outward to the west.
Hole 059 intersected the presumed up-dip, volcanic-hosted part of the Blue Sky shear zone ~50 m above
the diorite-hosted discovery intersection in Hole 055, cutting 7.60 m of 3.28 g/t Au from 137.4 m down-
hole (see Fig. 2), including 0.97 m of 16.20 g/t Au (see Table 2). Two narrower gold zones were
encountered higher in the hole, including 4.08 m of 2.05 g/t Au. Furthermore, the bottom sample from
the hole, spanning 0.9 m of altered volcanics, returned 4.85 g/t Au, suggesting the possible presence
~40 m north of Blue Sky of a significantly mineralized, volcanic-hosted shear zone similar to Thunder
North.
Table 2 - Significant gold intercepts of the shear-hosted type from the Thunder, Lightning and Blue Sky
trends. The Au-Ag-Pb-Zn zone intersected in Hole 058 is included but gold-bearing intercepts of the
porphyry Cu-Au type are excluded. The core diameter was NQ. Gold values are uncut. Samples with
Au grades greater than 15 g/t are shown individually. True widths have not been determined.

Next Steps
By successfully intersecting the Blue Sky gold zone 50 to 100 m above and up to 70 m northeast of the
Hole 055 discovery intersection, Holes 059 and 060 have provided sufficient orientation data to guide
placement of the drill holes that are being planned to follow the gold structure along strike and to depth.
Hole 061 also targeted the Blue Sky zone and the Au analyses pending from this hole should provide
additional control data. Hole 062, which targeted the eastern extension of Thunder North, is expected to
be similarly helpful there.
Methods and Qualified Person
The drill core was logged at Tower's leased, fully equipped core facility near Kamloops by and/or under
the direction Matthew Husslage, P.Geo. Mr. Husslage has managed or co-managed all of Tower’s Rabbit
North diamond drilling programs since the discovery of the Lightning Zone in December 2021.
Split samples of the core, generally 1.0 or 1.5 m in length, were delivered directly to Activation
Laboratories (ActLabs) in Kamloops, BC, a laboratory certified as ISO/IEC 17025 Accredited (Lab 790) by
the Standards Council of Canada. QA/QC samples including blanks and standards were inserted regularly
into the sample sequence at a ratio of approximately 1:20.
The samples were analyzed for Au by fire assay and ICP-OES and for Ag and 36 additional elements by ICP-
OES using a four-acid, near-total digestion. Any over-limit (>5 g/t) Au analyses were repeated using the
same fire assay procedure but with a gravimetric rather than ICP finish.
