Chargeability Anomaly at Bertha Zone
Edmonton, Alberta--(Newsfile Corp. - August 13, 2025) - Torr Metals Inc. (TSXV: TMET) ("
Torr"
or the
"
Company
") is pleased to announce results from a recently completed induced polarization (IP)
geophysical survey and rock grab sampling program at the Bertha Zone target within its highway-
accessible 332 km² Kolos Copper-Gold Project in south-central British Columbia.
Within the historical Bertha exploration pit ("Bertha") selected rock grab sampling expanded on a single
location of historical sampling, returning
up to 16.9% copper (Cu) and 8.48 grams per tonne (g/t)
silver (Ag)
from a series of paralleling quartz-carbonate veins along a 30 meter (m) strike-length. These
results validate the high-grade nature of the historical exploration pit, which reported past production of
30 tonnes averaging 2.14% Cu and 27.43 g/t Ag
1
. Additionally, mineralization continues
along a
>450 m west-southwest strike
between the Bertha and Bertha South showings ("Bertha Zone") with
no recorded drilling (Figure 1).
Importantly,
the high-grade copper mineralization is situated along the margins of a newly
defined IP chargeability anomaly exceeding 900 metres in strike length and over 500 metres in
width
, which remains open at depth, down-plunge, and to the east.
Highlights:
Broad, Open-Ended IP Chargeability Anomaly Coincident with Resistivity:
The IP survey
defines a >900 m long by >500 m wide chargeability anomaly, expanding to over 750 m centrally
where key north- and west-southwest-trending structures intersect. Chargeability appears tabular in
cross-section and strengthens eastward, remaining open in this direction near-surface as well as
down-dip and down-plunge >600 m vertical depth to the west-southwest, coinciding with a
resistivity high interpreted as a potential intrusive source or secondary porosity (Figure 1).
Evidence of Strong Structural Preparation:
All six rock grab samples from the Bertha Zone
consisted largely of chalcocite mineralization that returned >1% copper, with four exceeding 3%
and the highest yielding 16.9% Cu (Figure 1). Hosted within the same fragmental volcanic unit
(Late Triassic-Early Jurassic Nicola Group) as the historical Bertha exploration pit these results
suggest a broad supergene-style blanket where vertical downward-migrating high-grade copper
sulphides precipitated along pre-existing vein and fracture networks near the core of a porphyry
system (Figure 1).
Prime Untested Porphyry Drill Target Identified:
Southeast of the historical Bertha exploration
pit, a large hydrothermal alteration footprint coincides with overlapping chargeability (10-20 mV/V)
and resistivity (500-700 ohm-m) anomalies along the margins of a magnetic low, outlining a high-
priority, untested target with strong potential for a significant alkalic porphyry discovery (Figure 2).

"The confirmation of high-grade copper at-surface and identification of a large 0.7 km
2
IP geophysical
anomaly at Bertha represent a major step forward in defining the untested potential of this area," stated
Malcolm Dorsey, President and CEO. "The signature strength and dimensions are highly promising for
targeting a midsize high-grade porphyry system perhaps similar to the New Afton system, with a broad
moderate chargeability overlapping resistivity along the margins of a magnetic anomaly, together with
nearby evidence of high-grade supergene copper mineralization. We now have the geochemical and
geophysical data needed to plan drill targets in preparation for an inaugural drilling program at Bertha,
the first to test this previously untouched target."

Discussion: Chargeability Vectors for a New Afton Style Porphyry System
At the New Afton copper-gold alkalic porphyry deposit in south-central British Columbia, IP surveys have
been key to mapping copper sulphide mineralization and alteration at depth. Productive zones typically
show moderate chargeability of 10-15 mV/V, occasionally reaching up to 25 mV/V in the near-surface
supergene chalcocite zone
3
. While chargeability highs above 20 mV/V do occur, they are often linked to
non-economic pyrite-rich alteration halos or magnetite, making moderate chargeability a more reliable
vector for near-surface mineralization.
Comparatively at Bertha a 7-20 millivolts per volt (mV/V) chargeability feature overlaps a parallel,
plunging resistivity anomaly (500-700 ohm-m), potentially indicative of intrusive activity or secondary
porosity, the latter being a key feature exhibiting similar values that are associated with deeper
hypogene copper-gold mineralization at the New Afton deposit, 28 km to the northeast
2
. These
geophysical signatures together with recently compiled geochemistry (see
July 22, 2025 news release
)
underscore strong potential for the discovery of a significant untested copper-gold porphyry at Bertha,
largely hidden beneath a thin (<3 m) layer of younger Eocene volcanic cover that would have preserved
mineralization from glacial erosion.

Quality Assurance and Control
Results from samples were analyzed at ALS Global Laboratories (Geochemistry Division) in Kamloops,
Canada (an ISO/IEC 17025:2017 and ISO 9001:2015 accredited facility). A secure chain of custody is
maintained in transporting and storing of all samples. At ALS the samples were digested using Aqua
Regia and analyzed via ICP-MS and ICP-AES using a 25g sample aliquot under the ALS code AuME-
TL43. The Company follows industry standard procedures for the work carried out on the Kolos Project.
Due to the reconnaissance nature of the soil sampling the Company relied on the internal quality
assurance quality control ("QA/QC") measures of ALS. Torr Metals detected no significant QA/QC
issues during review of the data.
