Trident Intersects 1.32 g/t over 132.0m including 2.85 g/t over 40.3m from 22.0m Depth at its Preview SW Deposit, Located 2.5km Southeast of the Contact Lake Deposit, Confirming Both High-Grade and Bulk-Tonnage Potential of the La Ronge Gold Belt, Saskatchewan

Vancouver, BC, June 23rd, 2026 – Trident Resources Corp. (TSXV: ROCK) (OTCQB: TRDTF) (Frankfurt: 6BP0) (“Trident” or the “Company”) is pleased to announce inaugural assay results from eleven diamond drill holes completed during the 2026 winter drill program at the Preview South West Deposit, part of the Company's Contact Lake Gold Project in northern Saskatchewan. Preview Southwest is a cornerstone asset and target area within Trident's emerging district-scale exploration strategy in the La Ronge Gold Belt, one of Canada's up and coming premier mining jurisdictions. Together with the Contact Lake Deposit and several additional prospective target areas within a defined structural corridor, Preview Southwest forms part of a growing regional portfolio of deposits and targets that demonstrate the potential for significant resource expansion and new discoveries.

• Hole PR26007 returned 1.08 g/t Au over 77.59m from 120.91m

• The Preview Trend represents a string of mineralized bodies within a localized trend, with mineralization located close to surface; the Company intends to test the potential for additional mineralization along strike

• The summer 2026 drill program has recently commenced and will continue into the fall with an anticipated +20,000m of additional drilling

“The Preview Southwest results announced today represent the first holes drilled by Trident at the target area and mark a pivotal milestone in our pursuit to unlock the full value of the La Ronge Gold Belt,” stated Jonathan Wiesblatt, CEO of Trident Resources. “Preview is not just an exploration target; it is one of several cornerstone assets in a district-scale structural play that we believe has the potential to expand our existing mineral resource base. The continuity and consistency we are seeing at Preview SW, combined with the clear geological link to the high-grade Contact Lake mineralizing system, reinforces our conviction that there is substantial high-value resource growth ahead across our property package. Building on very successful fall 2025 and winter 2026 drill campaigns, we have launched a +20,000 metre summer drilling program at the Contact Lake Gold Project, with a primary focus on expanding the Contact Lake deposit while also growing the Preview SW deposit. With approximately $26 million in cash on our balance sheet, Trident is well funded to execute aggressively on this program and to continue converting our exploration success into high-value gold ounces for our shareholders.”

Summary of Drilling:

The Preview Trend spans over 7.0km and hosts the Preview SW and Preview North deposits in addition to five other distinct gold-bearing zones. Preview SW and Preview North host current Mineral Resource Estimates that together contain over 350,000 oz Au in the Indicated category and 540,000 oz Au in the Inferred category (see Trident news release November 24, 2025). The Preview SW deposit is located 2.5km SE of the Contact Lake deposit and past producing mine within in a parallel shear zone. Though currently being advanced as a lower-grade, bulk-tonnage deposit, high-grade mineralization has been encountered historically in drilling, with previous operators reporting 633.61 g/t Au over 4.08m, including 1,123.25 g/t Au over 2.30m including 4279.00 g/t Au over 0.6m (Comstock Resources news release March 4, 2013)*.

*The drill results reported above are historical in nature and were completed by previous operators on the property. A Qualified Person (QP) has not completed sufficient work to verify these historical drilling results, as the original core, assay certificates, split samples, and quality assurance/quality control (QA/QC) protocols from these programs are either partially unavailable or have not yet been fully audited. Accordingly, these historical results are unverified and should not be relied upon.

Mineralization along the Preview Trend is interpreted to be directly related to the mineralizing system at the nearby Contact Lake deposit, reinforcing the Company’s view that the entire La Ronge Gold Belt corridor represents a cohesive, district-scale structural play with substantial high-value gold ounce growth potential.

Table 1: Mineral Resource Estimate

Notes to the Resource Estimate Tables:

1. The Mineral Resource Estimates was completed by Sue Bird, P.Eng., with an effective date of November 6, 2025.
2. 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:
   • Metal price of US$2,600/oz Au;
   • Payable metal of 99% for Au;
   • Offsite costs (TC/RC/Transport) for Au of US$5.80/oz;
   • Pit slopes are 45 degrees;
   • Mining cost of mineralized material of CDN$2.56/t and CDN$2.40/t for waste, and;
   • Processing costs of CDN$15.60/t with G&A costs of CDN$7.20/t.
3. Metallurgical recoveries are 90% for all deposits.
4. Forex = 0.72 $US:$CDN
5. The NSR equation is: NSR (CDN$/t) = (Au*90%*CDN$114.68/g)
6. The specific gravity for each deposit and lithologies or domains ranges from 2.40 to 2.91.
7. Numbers may not add due to rounding.

The winter drill phase at Preview comprised 3,142.0m in eleven holes. Eight of the holes were collared at the Preview SW deposit and three were drilled at Preview Zone C, an under-explored area that is located 1.5km NE of Preview SW and 600m SW of Preview North. Drilling at Zone C confirmed that significant gold mineralization is present along the entire Preview Trend. The eight drill holes at Preview SW were designed to both infill and expand the current pit-constrained resource area. Drilling confirmed that material gold mineralization is present below and along the margins of the currently defined limits of the deposit, which remains open for expansion in all directions.

Gold mineralization is structurally controlled in quartz veins within or on the margin of sheared diorite sills, which extend 5.2km along the trend. Both Preview SW and Preview North are comprised of multiple sub-parallel shear structures that bifurcate and merge along their length and are persistent at depth.

Contact Lake Gold Project Overview:

The Contact Lake Gold Project covers approximately 22,790 hectares and includes the past-producing Contact Lake gold mine, which produced approx. 190,000 ounces of gold at an average head grade of 6.16 g/t Au during active mining operations between 1994 to 1998. At the time of mine closure, the price of gold hovered around USD $300/oz and Cameco Corporation reported that substantial gold resources were left unmined. Situated in the highly prospective La Ronge Gold Belt of Saskatchewan, the Contact Lake Property also hosts the Preview SW, Preview North and the North Lake orogenic gold deposits.

Along with the Greywacke North deposit (located by road 40km northeast of Contact Lake), these four deposits are wholly-owned by Trident Resources and together comprise a current Mineral Resource of more than 2.0 million ounces of gold. These estimates are supported by Mineral Resource Estimates (Trident news release November 24, 2025) which do not include any gold-related ounces from the past-producing Contact Lake target area. Trident believes that significant additional high-value resource growth opportunities exist across all of its assets, and that the Contact Lake Gold Project as a whole — anchored by Contact Lake and advanced by Preview — represents one of the most compelling development opportunities in the La Ronge Gold Belt.

Quality Assurance and Quality Control:

All drill core is logged, photographed and cut in half with a diamond saw. Half of the core is placed in sealed poly bags with unique identification numbers and transported to ALS Global in Saskatoon, Saskatchewan for analysis, while the other half is archived and stored on site for verification and reference purposes.

At the lab, samples are received and digitally recorded then dried and pulverized into a fine powder. Gold is assayed using a 30g fire assay method and 49 additional elements are analyzed by Inductively Coupled Plasma (ICP) utilizing a 4-acid digestion. Secondary metallic screen analyses are performed on select mineralized zones and all samples that return >3 g/t Au to quantify the nugget effect of the gold mineralization. Quality Assurance and Quality Control (QAQC) samples including field blanks, duplicates and lab-certified standards are inserted in the sample stream at a rate of greater than 10% of all samples submitted to the lab. ALS Global also conducts their own internal QAQC protocol.
