Tower Reports Exceptional Exploration Success on its October Drilling Program at Rabbit North,
Discovers the Faulted Western Half of the Lightning Zone and a New, More Strongly Mineralized Gold
Zone, “Blue Sky”, 300 m to the North
Vancouver, B.C. – October 31, 2024 - Tower Resources Ltd. (“Tower” or the “Company”) (TSXV: TWR) is
pleased to report that its 4-hole October drilling program on the Rabbit North property in the heart of the
Kamloops mining district (see Fig. 1) appears to have been the most successful to date, intersecting shear
hosted, Lightning-type mineralization in every hole and discovering not only the faulted western half of
the Lightning Zone but also a completely new and more strongly mineralized gold zone – “Blue Sky” –
that significantly expands the gold potential of the property.

Drilling Summary
Four holes, Nos. RN24-055 to 058, were drilled for a total of 1096 metres. All of the core except that from
the Chilcotin cover basalts has been cut and submitted for analysis, along with previously uncut core from
Holes 052 and 053 of the June drilling program.
New Hole 055 Au Discovery – the “Blue Sky” Zone
Hole RN24-055 was drilled 300 m north of the Lightning Zone (see Fig. 2) to crosscut a historical (2004)
porphyry Cu-Au exploration hole that was drilled vertically and intersected several quartz-sericite-pyrite
(“QSP”) altered shear zones containing significant Au but no Cu – hallmarks of Tower’s earlier Thunder
and Lightning orogenic Au discoveries.
Drilled to the northwest at a -60° dip, Hole 055 intersected a 32.5 m wide, intensely QSP altered and
quartz veined (see Fig. 3) shear zone straddling the contact between Durand Stock diorite and Nicola
volcanics, 254 to 286.5 m down-hole. Core angles suggest a true thickness of roughly 25 metres.
Figure 2 – Location of the new Blue Sky gold zone relative to the Thunder and Lightning Au trends and
the Durand Stock. The Au grade x metres value for significant Au intersections in previous
drill holes are used by Tower for exploration targeting only; they are not indicative of the
economic potential of the mineralization.
Figure 3 – Selected photos of analyzed drill core from the Blue Sky Zone: (a) intensely QSP-altered to
quartz-veined diorite from 1.0 m sample interval containing 7.03 g/t Au; (b) intensely QSP-
altered diorite cut by a late chalcopyrite vein, from 0.85 m sample interval containing 8.78
g/t Au.
The QSP alteration in Hole 055 is even more intense than that in the Thunder and Lightning Zones.
Approximately 25% of the 32.5 m mineralized zone consists of brecciated quartz veins (see Fig. 3a) and
the rest is generally so intensely silicified and pyritized (see Figs. 3a,b) that its protolith is unrecognizable.
Seven test samples from the top half of the 32.5 m section (see Table 1) were assayed on a “rush” basis
during the drilling program. All returned significant Au values ranging from 1.6 to 8.8 g/t and averaging
4.0 g/t, nearly three times the 1.5 g/t grade of the Lightning Zone.

Table 1 – Comparison of the Au and pyrite contents of the drill core from the Blue Sky Zone. Only
seven samples, all from the top half of the zone, have been analyzed. Most but not all
pyrite-rich samples yielded higher Au assays than samples containing less pyrite. Note that
the bottom half of the gold zone tends to contain more pyrite.
Of the seven analyzed samples, those with the most pyrite tend to contain the most gold, although not in
all cases. The core from the unanalyzed bottom half of the section contains significantly more pyrite
(typically 35-45% versus 5-25%), suggesting that it may also have a higher Au content.
In addition to revealing the grade potential of the orogenic Au system at Rabbit North, the Hole 055
discovery expands the target area both northward from the Thunder–Lightning trend and eastward into
the Durand Stock, possibly for 1.2 km to a vertical 1990 percussion drill hole that intersected 39.7 m of
1.75 g/t Au (see Fig. 2) and was never followed up by diamond drilling. For this reason the discovery has
been named “Blue Sky”.
Two significant, 3.7 and 8.8 m intervals within the overall 32.5 m zone contain ~10% chalcopyrite (see
Table 1) in the form of discrete veins. These veins cross-cut the pyrite mineralization and thus appear to
be unrelated to the older (~215 Ma versus 149 Ma) porphyry Cu-Au mineralization associated with the
Durand Stock. The presence of chalcopyrite in gold-bearing drill core along the Thunder–Lightning trend
is generally undesirable because it has consistently indicated that the gold mineralization is of the older,
low-grade porphyry type rather than the higher-grade orogenic type that Tower is primarily targeting. The
younger variety of chalcopyrite in the Blue Sky Zone may, however, prove to be beneficial because the
highest Au assay obtained from the seven test samples – 8.78 g/t – was from the only sample with
chalcopyrite veins. The Cu analyses are pending.
Both Hole 055 and the historical 2004 hole on which it was based were collared on the northern band of
young Chilcotin basalt flows near the western edge of the Durand Stock (see Fig. 2). Below this basalt
cover, Hole 055 intersected Durand diorite to 275.9 m, in the middle of the Blue Sky Zone, followed by
alternating intervals of Nicola andesite flows and Durand diorite dykes. The hole was initially terminated
at 272 m while still in the gold zone. Following receipt of the seven positive Au assays, it was re-entered
and deepened to 332 metres.
The diorite above the Blue Sky Zone contains two QSP-altered dykes of quartz-feldspar porphyry similar
to those that occur in association with the Thunder and Lightning gold mineralization. It also contains
three shear zones 14 to 34 m wide (core length) that are less altered than Blue Sky but still contain
significant pyrite (2 to 5%) and, locally, may also contain significant gold. The vertical historical hole may
have followed the edge of one of these shear zones as it encountered several shorter but similarly sheared
and altered sections including a 7.5 m interval that averaged 1.48 g/t Au.
The projected surface footprint of the Blue Sky Zone, assuming a vertical dip, is ~50 m north of the mapped
limit of the Chilcotin cover basalts (see Fig. 2), implying that the top of the zone was glaciated.
Furthermore, the projected footprint is directly up-ice from the strong, axial zone of the Dominic Lake
gold grain dispersal train (see Fig. 4), the western part of which led to the discovery of the Lightning Zone.
These features, together with the apparently higher Au grade of the Blue Sky Zone, suggest that Blue Sky
is the principal gold grain source for the core of the dispersal train.
Figure 4 – Location of the new Blue Sky Au discovery in relation to the Dominic Lake gold grain
dispersal train in the glacial till. Blue Sky appears to account for the strong central part of
the train.
Hole 056 Extends Thunder North Zone 150 m to East
Hole 056 was drilled on the Thunder North trend ~150 m east along strike from the discovery hole, RN23-
039 (see Fig. 2). It intersected 15.8 m of lapilli to block tuff from 139.5 to 155.4 m down-hole that is visually
as intensely QSP altered as the 25.0 m section in Hole 039 that averaged 2.07 g/t Au. Importantly, the
small diorite plug that restricted the thickness of the gold zone in an earlier follow-up hole (No. 040) drilled
50 m east of Hole 039 does not extend as far east as Hole 056, leaving the zone open for expansion in this
direction.
Hole 057 Finds Western Half of Faulted Lightning Zone
Hole 057 was drilled ~150 m west of Lightning Zone discovery hole No. RN21-026, on the west side of a
N-S fault that was previously thought to completely cut off the gold zone. Within a 94.3 m section
extending from 43.0 to 137.3 m down-hole and dominated by andesitic lapilli tuff, the main host rock of
the Lightning Zone, Hole 057 crossed six strongly sheared and QSP-altered intervals – apparently a series
of “horsetail” shears – ranging in width from 2.3 to 15.45 m and aggregating 56.9 m, or 60.3% of the
overall 94.3 m section. The sheared tuff tends to be sericite rich with a soft, clay-like consistency.
The tuff hosting the Lightning Zone is similarly horsetail sheared and sericitized, and the disseminated
pyrite mineralization in both cases has a spotted, rash-like “disease” texture (see Fig. 5). These shared
features strongly suggest that the Hole 057 intersection represents the faulted western half of the
Lightning Zone.
Figure 5 – Pyrite veined and "diseased" drill core from (a) Holes 057 west of the Lightning Zone and
(b) Hole 026, the original Lightning Zone discovery hole drilled in 2021. This type of pyrite
mineralization is specific to the Lightning Zone indicating , together with other shared
features of the core, that Hole 057 intersected the faulted western extension of the zone.
Hole 058 Obtains a Deeper Cut of the High-Grade Hole 051 Shear Zone
Hole 058 was drilled midway between the Thunder and Lightning Zones, on-section with June’s Hole 051
which intersected 4.27 m of 6.06 g/t Au, but at a steeper dip (75° v ersus 50°) with the objective of
obtaining a second, deeper intersection and thereby determining the dip of the gold zone. A similar, 4.0
m section of intensely sheared and QSP-altered tuff, visually compatible with the Hole 051 shear zone and
indicative of a steep southerly dip, was obtained from 275.5 to 279.5 m down-hole. Unusually, the pyrite
mineralization is accompanied by 5 to 10% galena.
Follow-up Drilling Plans
Drilling can be done year-round at Rabbit North. The next drilling program is now being planned and will
be finalized once all assays from the present program have been received.
Methods and Qualified Person
The drill core was logged at Tower's leased, fully equipped core facility near Kamloops by Matthew
Husslage, P.Geo. and Ryan Parsons, G.I.T. 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 are being 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 are repeated using
the same fire assay procedure but with a gravimetric rather than ICP finish.
