Canuc Completes Gold Assay Verification Program at ESP
Canuc Resources Corporation (“Canuc” or the “Company”) (TSX -V: CDA, OTCQB: CNUCF,
WKN: A14ZX4) is pleased to report on the positive confirmation results of a gold assay
verification program conducted on lab reject samples from the Company’s East Sudbury Project
“ESP’. This assay verification program was undertaken in order to comprehensively check and
confirm the significant number of gold assays which had been reported for the property over its
history of more than 32,685 meters of drilling spanning three decades.
Canuc acquired 100% ownership of the ESP by purchasing MacDonald Mines Exploration Ltd.
(MacDonald Mines) on May 8 th, 2025. Since that time, the company has focused on verification
of data and information relating to numerous gold prospects within the property as well as
evaluation of other copper-gold-cobalt and related critical mineral occurrences.
Drill core, totalling 32,685 m, is stored at the Scadding Mine site in the western part of the ESP.
The core is from historical drilling programs carried out by Trueclaim Exploration Inc. (2009 to
2011), Northern Sphere Mining Ltd. (2017) and MacDonald Mines (2019 to 2025). Casing for
most of these holes is in place, and easily loca table. Reject material from a large proportion of
MacDonald Mines and Trueclaim drilling programs a re also stored on site . A comprehensive
review and categorization process for the available sample materials has been undertaken to
confirm both the authenticity, and the accuracy, of historical gold grades reported for the Scadding
Gold Mine system and surrounding area. The principal focus of this verification program was on
re-assaying the reject material from sections of available holes in which either high gold values
were reported, or visible gold (VG) was noted in the drill logs and from which gold values were
returned from assaying. To complete this verification program, eighty-five (85) samples from 17
holes along with 7 certified reference materials and 6 “blank” duplicates were submitted to
Activation Laboratories Ltd. (Actlabs) for gold analysis.
The principal conclusion from th is re-assaying and core examination program is that historically
reported gold assays are supported by verification. T here is a nonmaterial statistical variance
between reported gold assays and checked gold assays, and therefore there remain no outstanding
issues with the results from previous gold sampling and assaying at the Scadding Gold Mine.
On average, the assay results from the duplicate reject samples compare very favourably with the
original assay results. The data demonstrates a very strong correlation between duplicate and
original assay results from samples containing gold values that are less than 5 g/t . Samples that
are greater than 5 g/t show a higher variability in gold grades. For example, the original assay for
one sample (from Hole SM-20-41) assayed 34.4 g/t Au but the reject test assayed 82.7 g/t Au. In
some cases, the assay of the reject sample was lower than the original with the most severe decrease
being 0.804 g/t Au compared to an original of 22.3 g/t Au. Of the 18 samples that were greater
than 5 g/t Au, the average value for the original samples was 12.64 g/t Au and the average value
for the reject test samples was 13.35 g/t Au. The average value of the 85 reject samples was 3.92
g/t compared to the average value of the original assaying of 3.82 g/t Au.

A high degree of variability between duplicate assays is most likely due to a non -uniform
distribution of coarse gold particles which occur locally within the mineralized zones. This is a
common issue with gold deposits that contain coarse gold. More representative assay values can
be determined using metallic screen analys es. A metallic screen analysis consists of one assay
from the coarser fraction and a second assay from the finer fraction of a sample. The two weighted
values are then combined to provide a more representative average gold value. The companies
previously involved with ESP were aware of this issue and were diligent in re-assaying the higher-
grade material using screen metallic analytical methods so the gold values that are in the current
drill sample database are considered to be acceptable estimates of the gold grades. All future gold
assaying will use a larger sample (50 grams compared to 30 grams) and all initial assay results
greater than 5 g/t will be re-assayed using the coarse metallic method.
One of the principal observations made during this exercise was the presence of coarse visible gold
in all drill core that was examined in the sections where gold values exceed 5 g/t. When values
were lower in grade, e.g. below 5 g/t Au, there often is visible gold but it is very fine grained and
typically only visible under a microscope.
“This important work confirms the extensive records for gold mineralization in the high-grade
gold system of the Scadding Gold Mine and surrounding claims. Our next step will be to further
quantify, and then to pursue development of, the high-grade gold lenses which are located near to
the abandoned gold mine workings found across the property.”
“Perhaps more importantly, we have now also secured the confirmation we sought to pursue more
expansive geological models. These models include the pro spect of the Scadding Gold Mine
system and surrounding gold deposits having been generated from, and being located proximal to,
a classic IOCG deposit type gold metal endowment. Further exploration work to test this exciting
and transformational hypothesis is now being planned for the project,” stated Christopher Berlet,
President & CEO of Canuc Resources Corp.

About Canuc Resources Corp.
Canuc Resources Corporation is a junior resource company developing its 100% interest in the
East Sudbury Project (“ESP”) which spans 19,710 hectares and is centered approximately 20
kilometers northeast of the Prolific Sudbury Mining Camp and near to the extensive infrastructure
of the adjacent Sudbury Mining District. ESP encompasses several centers of critical and precious
metal mineralization interpreted to be related to a mineral system that can form IOCG and affiliated
critical and precious mineral deposits. Included within the Project is the historical Scadding Gold
Mine and associated Scadding Gold Tailings Project.

Canuc also holds a 100% interest in the San Javier Silver-Gold Project located in Sonora State,
Mexico. The San Javier Silver-Gold Project spans 28 claims covering 1,052 hectares and evidences
extensive silver, gold and copper mineralization interpreted to be related to a mineral system that
can form silver-dominant IOCG and affiliated deposits.
Canuc generates cash flow from natural gas production at its MidTex Energy Project located in
Central West Texas, USA where Canuc has an interest in eight (8) producing natural gas wells and
has rights for further in field developments. The Company also receives a 4% Net Smelter Royalty
from gold production at the Scadding Gold Tailings Project located on Mining Claim LEA
