NEWS RELEASE
Trident Resources Corp. Announces Updated Mineral Resource Estimates for Four La
Ronge Gold Belt Deposits in Northern Saskatchewan, Canada
Vancouver, BC, November 24, 2025 – Trident Resources Corp. (TSXV: ROCK) (OTCQB:
TRDTF) (“Trident” or the “ Company”) is pleased to announce that it has received updated
Mineral Resource Estimates for its Preview SW, Preview North, North Lake and Greywacke
gold deposits. The updated Mineral Resource Estimates were prepared by Bird Resource
Consulting Corp. (BRCC) and represent an 18% increase in Indicated gold (Au) ounces now
totaling 896,500 combined ounces, and a 190% increase in Inferred gold ounces now totaling
1,129,600 combined ounces across the four deposits when compared to the historical MRE’s
calculated in 2021 (Greywacke) and 2022 (Preview SW, Preview North and North Lake). All four
of these deposits are wholly-owned by Trident Resources and are located in the prolific yet under-
explored La Ronge Gold Belt of northern Saskatchewan. The Mineral Resource Estimate has an
effective date of November 6, 2025.
Highlights:
• Trident reports a significant upgrade to the existing Mineral Resource Estimate using
US$2,600 / oz gold (previously calculated at US$1,500 / oz - US$1,700 / oz):
▪ 18% increase to Indicated resource gold ounces
▪ 190% increase to Inferred resource gold ounces
• Indicated resources at Trident’s 100% owned Preview SW, Preview North, Greywacke
and North Lake deposits total 896,500 combined gold ounces (see Table 1)
• Inferred resources at Preview SW, Preview North, Greywacke and North Lake deposits
total 1,129,600 combined gold ounces (see Table 1)
• Drilling recently completed on the Contact Lake Project, with 3 of 19 holes reported,
including Hole CL25003 which returned 7.03 gpt gold over 43.25m, including 30.06 gpt
gold over 9.25m; this updated Mineral Resource Estimate does not include recent
nor historical Contact Lake drill results.
Jonathan Wiesblatt, Chief Executive Officer of Trident, commented: “ When we merged Eros
Resources, MAS Gold, and Rockridge Resources earlier this year, our vision was clear — to
create a Saskatchewan-focused gold exploration company with scale and momentum. Today’s
updated Mineral Resource Estimate delivers on that promise, confirming the quality and potential
of all four highlighted deposits. But this is only the beginning. With strong funding, a growing asset
base, and an ambitious exploration program ahead, we’re poised to unlock even greater value in
the La Ronge Gold Belt — and the next phase of our growth story is about to unfold.”
Mr. Wiesblatt continued “With these results, the Company now hosts more than 0.9 million ounces
(24.7Mt at 1.13 g/t) of Indicated mineral resources and 1.1 million ounces (38.6Mt at 0.91 g/t)
Inferred mineral resources, marking a significant milestone in our growth. Importantly, we see
clear potential to expand these totals even further through our ambitious exploration programs
planned for the coming months. Reaching this scale in one of the world’s top mining jurisdictions
puts the Company firmly on the radar of the broader gold industry and strengthens our strategic
position for future development. Trident management eagerly awaits additional analytical results
from its recently completed Contact Lake drilling program, where results to date suggest that a
robust gold-mineralized system may exist outside of, but proximal to existing historical mining
infrastructure.”
Trident commissioned Bird Resource Consulting Corp. (BRCC) to update its Mineral Resource
Estimates to coincide with the recent formation of the Company and to better reflect the value of
their Saskatchewan gold properties given current commodity prices. Additionally, the Company
continues to execute its exploration program at Contact Lake, a former producing gold mine that
was shut down in 1998 when the average gold price was approximately $300 (USD) per troy
ounce. Contact Lake was not included in the updated Mineral Resou rce Estimate yet remains a
flagship project for the Company with significant exploration potential.

Notes to the Resource Estimate Tables:
• The Mineral Resource Estimates was completed by Sue Bird, P.Eng. who is independent of the
Company, with an effective date of November 6, 2025.
• The Mineral Resource Estimate for all four deposits have been confined by an open pit with
“reasonable prospects of eventual economic extraction” using the following assumptions:
o Metal price of US$2,600/oz Au;
o Payable metal of 99% for Au;
o Offsite costs (TC/RC/Transport) for Au of US$5.80/oz;
o Pit slopes are 45 degrees;
o Mining cost of mineralized material of CDN$2.56/t and CDN$2.40/t for waste , and;
o Processing costs of CDN$15.60/t with G&A costs of CDN$7.20/t.
• Metallurgical recoveries are 90% for all deposits.
• Forex = 0.72 $US:$CDN
• The NSR equation is: NSR (CDN$/t) = (Au*90%*CDN$114.68/g)
• The specific gravity for each deposit and lithologies or domains ranges from 2.40 to 2.91.
• Numbers may not add due to rounding.
Preview SW Deposit (Contact Lake Property):
The Preview SW deposit is a shear -hosted gold deposit located 2.5 km southeast of Trident’s
Contact Lake gold project, a past-producing gold mine at which a 6,838m drill program was just
completed. The Preview SW deposit is hosted in several NE trending sub -parallel zones within
sheared dioritic to gabbroic rocks located near the meeting point of the La Ronge, Kisseynew and
Glennie Domains. The most recent historical Mineral Resource Estimate for Preview SW had an
effective date of October 31, 2022. The updated Mineral Resource Estimate is as follows:

North Lake Deposit (Contact Lake Property):
The North Lake deposit is a vein-hosted mesothermal gold deposit located along the margins of
the La Ronge and Kisseynew Domains within the La Ronge Gold Belt. The deposit forms a
branching and elongate zone within a felsic metavolcanic host that has been metamorphosed to
the upper amphibolite facies. Gold mineralization is hosted in sheeted quartz veins that are
roughly parallel to regional foliation and also in quartz tension veins that are at high angles to the
foliation. The last Mineral Resource Estimate for North Lake had an effective date of October 1,
2022. The updated Mineral Resource Estimate is as follows:

Greywacke Deposit (Greywacke Lake Property):
The Greywacke deposit is a disseminated gold-sulfide deposit hosted in metasedimentary rocks
located along the margin of the La Ronge and Kisseynew Domains within the La Ronge Gold
Belt. The host arenite and arkose metasediments trends NE and dip steeply toward the northwest
and have been metamorphosed to the upper Amphibolite facies. The Greywacke gold
mineralization is found in discrete parallel zones of gold -enriched disseminated sulfide . The
Greywacke mineralized trend extends for over 7 km in a NE -SW direction and features several
gold showings in identical geological settings to the mineralization discovered at the north zone.
The previous Miner al Resource Estimate for Greywacke had an effective date of December 1,
2021 and incorporated surface channel samples that were not used to calculate the current MRE.

Mineral resources that are not mineral reserves do not have demonstrated economic viability;
however, a reasonable prospect of eventual economic extraction pit has been used to confine the
Resource Estimate using parameters detailed in the table notes. Inferred mineral resources are
subject to uncertainty as to their existence and as to their economic and legal feasibility. The level
of geological uncertainty associated with an Inferred mineral resource is too high to apply relevant
technical and economi c factors likely to influence the prospects of economic extraction in a
manner useful for evaluation of economic viability.
The QP for the Mineral Resource Estimate is not aware of any environmental, permitting, legal,
title, taxation, socio-economic, marketing, political, or other relevant factors that could materially
affect the potential development of Mineral Resource Estimate. Factors that may affect the
estimates include: metal price assumptions, changes in interpretations of mineralization geometry
and continuity of mineralization zones, changes to interpolation assumptions, metallurgical
recovery assumptions, operating cost assumptions, confidence in the modifying factors, including
assumptions that surface rights to allow mining infrastructure to be constructed will be
forthcoming, delays or other issues in reaching agreements with local or regulatory authorities
and stakeholders, and changes in land tenure requirements or in permitting requirement.
Modelling Methodology:
For each deposit the assay data was examined within the domains using cumulative probability
plots (CPPs) to cap the assay data at high grade values that deviate from the lognormal
distribution. In addition, where warranted, and to ensure the model validates with the de-clustered
composite data, the composites were restricted during interpolations at high grade values that
unduly influenced the mean grades. Table 7 summarizes the capping and outlier restriction values
used for each deposit.

For the first two passes the outlier is capped at the outlier value, for the
third and fourth pass composites above the outlier value are not used.
The interpolations of the Au grade have been done using inversed distance cubed (ID3) with
matching of domains and of the Indicator model “Au Indicator” domain. The Au Indicator domains
have been created within each domain using inverse distance squared interpolations to determine
the probability of the Au grade to be above 0.3 g/t. If the probability of the block to be above this
cutoff is greater than 50% than the domain is considered within a “Au Indicator” domain.
In each case the Au interpolations have been completed in 4 passes with the search parameters
increasing for each pass. The first 3 passes require at least two drillholes, with the fourth passes
relaxed to allow only one drillhole if necessary. The distances and directions used for each pass
are based on the variography completed for each domain where sufficient data was available, as
well as on the orientation of the mineralization.
Classification:
Classification of each deposit has used the distance to drillholes as a proxy for the required
drillhole spacing for material to be considered Indicated. Blocks not meeting the criteria that have
been interpolated with a n Au grade are considered Inferred. This distance corresponds to the
range between 80%-90% of the sills for the variogram models. For example, the criteria of having
an average distance to 2 drillholes of 22m also uses the criteria of the furthest distance to one of
these two drillholes to be 31m. The 31m distance is the hypotenuse of a right-angled triangle with
side of 22m, thus approximating a drillhole spacing of 22m.

Model Validations:
The models have been validated by comparing the mean modelled grades at zero cutoff to the
de-clustered composite (Nearest Neighbour model) mean grades. The modelled tonnage and
mean grade above cutoff have also been validated for the entire grade distribution, through
comparisons of the metal content at several cutoffs.
