Vancouver, BC, Nov. 24, 2025 (GLOBE NEWSWIRE) -- 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 Resource Estimate yet remains a flagship project for the Company with significant exploration potential.

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 Mineral 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. The updated Mineral Resource Estimate is as follows:

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 economic 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.

Table 7: Summary of Capping and Outlier Restriction

Deposit	Domain	Cap value (g/t)	Outlier Restriction (g/t)	Outlier Distance (m)
North Lake	1	30	10	5
	2	10	3	5
Preview SW	1	70	15	5
	2	30	15	5
	3	6	4	5
	4	6	4	5
	5	10	5	5
Preview North	7	50	na	na
	8	10	na	na
	9	10	na	na
Greywacke	1	50	10	5
	2	2.5	3	5
	3	25	3	5
	4	10	3	5
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 an 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.
  

Table 8: Classification Requirements

Deposit	Avg. Distance to 2 DHs (m)	Furthest Distance to DH (m)
North Lake	40	57
Preview SW	22	31
Preview North	22	31
Greywacke	22	31

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.
