Cosa Resources Announces Summer Drill Plans For The Darby Joint Venture With Denison Mines Cosa Resources announced summer plans for the Company's Darby project. Darby is a joint venture between Cosa and Denison Mines and is located 10 kilometres west of Cameco's Cigar Lake Mine in the eastern Athabasca Basin, Saskatchewan. Cosa is the operator of Darby and holds a 70% interest with Denison holding a 30% interest. Drilling at Darby is expected after completion of a significant drill program at the Company's Murphy Lake North joint venture to follow up uranium mineralization intersected in winter 2026. Drilling is planned at the Gamma trend to follow up structure, alteration, and strongly anomalous uranium geochemistry intersected during the winter 2026 drill program. Drilling is planned at the Bravo trend to follow up weak uranium mineralization proximal to structure and alteration intersected by historical drilling. Drilling at Darby is planned to comprise up to 2,000 metres at the Gamma and Bravo trends. Drilling at Gamma will follow up Cosa's winter 2026 drill program which intersected a broad zone of structure with significant unconformity offset, alteration, and elevated to strongly anomalous uranium geochemistry on trend with historical uranium mineralization. Drilling at Bravo will follow up compelling historical results including structure, alteration, and uranium mineralization. The Company remains on schedule and expects to announce the commencement of drilling at the Murphy Lake North joint venture in the coming days. Drilling at Murphy Lake North is expected to take a minimum of two months to complete and will be followed by drilling at Darby. Located 10 kilometres west of the Cigar Lake Mine, Darby contains multiple prospective conductive trends and several intersections of weak uranium mineralization. Historical drilling indicates that many of these trends are highly prospective for uranium deposits characteristic of the eastern Athabasca Basin, yet most of the strike length has not been effectively evaluated. Work by Cosa in 2025 prioritized these trends and identified several historical drill holes with results that suggest proximity to uranium mineralization. Initial drilling results from winter 2026 significantly upgraded multiple trends. Summer drilling is expected to commence in late August and will include follow up of anomalous results from both winter 2026 and historical drilling. Historical drilling and geophysical results for Darby were sourced from the Saskatchewan Mineral Assessment Database (SMAD). SMAD sources for Darby include file numbers 74H14-0021, 74H14-0023, 74H15-0041, 74H15-0053, 74H15-0055, 74H15-0056, 74H15-0066, 74H15-0067, 74I02-0031, 74I02-0042, 74I02-0053, 74I02-0080, 74I02-0095, and MAW00516. Some confidential data and reports not presently available via SMAD were supplied to Cosa by Denison. Verification of historical drilling results included confirming historical drill hole collar locations from air photos and ground checking selected collars with a handheld GPS unit. Basement and lower sandstone sections from most historical drill holes were relogged in 2024 and 2025 by Cosa. Verification of geochemical results for drill holes completed between 2008 and 2010 was facilitated by the reissuance of analytical certificates to Cosa by the Saskatchewan Research Council (SRC). Cosa thanks the SRC for its valued assistance in increasing confidence in the historical dataset. Verification of historical geophysical results included confirming the locations of geophysical survey grids from air photos, compiling survey data and interpretations, and evaluating whether interpreted geophysical results could be reasonably explained by historical and current drilling results. Samples from Cosa's drilling were transported to SRC Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan (ISO/IEC 17025:2005 accredited) for U3O8 assay and multielement analysis. Cosa inserts certified reference material (CRM) blanks and standards into the split core sample series as a QA/QC measure. SRC conducts a QA/QC programme which includes repeat analyses and insertion of CRM standards CAR218, BL4A, and BL2A, as appropriate. SRC's CRM results are verified by Cosa staff. The Company's disclosure of technical or scientific information in this press release has been reviewed and approved by Andy Carmichael, P.Geo., Vice President, Exploration for Cosa. Mr. Carmichael is a Qualified Person as defined under the terms of National Instrument 43-101. Tillkännagivande • Jun 05

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 32% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 56% per year over the past 5 years. Shareholders have been substantially diluted in the past year (32% increase in shares outstanding). Revenue is less than US$1m. Minor Risks Share price has been volatile over the past 3 months (17% average weekly change). Market cap is less than US$100m (CA$85.6m market cap, or US$62.5m). Tillkännagivande • Apr 15
Cosa Resources Corp Reports Anomalous Radioactivity in Multiple Drill Holes At Murphy Lake North Joint Venture with Denison Mines Corp Cosa Resources Corp. reported the intersection of anomalous radioactivity in multiple drill holes and completion of the winter 2026 drilling program at the Company's Murphy Lake North Project. Radioactivity intersected in three drill holes. Radioactivity remains open in multiple directions including for at least 600 metres along strike to the east and 600 metres to the west within the larger kilometre-scale Cyclone alteration zone. Depth of the radioactivity is shallow at approximately 260 metres vertically from surface. Cyclone trend structural corridor is over 100 metres wide and hosts significant alteration consistent with major eastern Athabasca uranium deposits. Winter drilling at MLN followed up structure and alteration intersected at the Cyclone trend in summer 2025. Five drill holes totaling 2,015 metres were completed during the program with three drill holes intersecting anomalous radioactivity. The first drill hole of the program, MLN26-013, intersected the strongest radioactivity including a 5.0 metre interval of continuously anomalous radioactivity in the upper basement. Two holes were completed to directly follow up radioactivity in MLN26-013. Two additional holes were completed to define underlying geology ahead of summer drilling and follow up another radioactive intersection. All drill holes were completed on Section 3200E. Three of five drill holes intersected anomalous radioactivity in two discrete zones. Drilling also defined highly prospective geology with similarities to the Hurricane deposit and other unconformity related uranium deposits of the eastern Athabasca Basin. Multiple intervals of anomalous radioactivity were intersected in two discrete zones. All radioactive intersections are associated with faulting and broad zones of strong hydrothermal alteration in the sandstone and basement. All radioactive intersections remain open along strike to the east and west for at least 600 metres and some intersections remain open on section. MLN26-013, the first hole of the winter program, intersected a significant zone of structure and alteration underlain by faulted graphitic gneiss hosting several intervals of anomalous radioactivity between 306.5 and 313.5 metres ranging from 400 to 13,900 cps. Radioactivity in MLN26-013 was followed up to the north (MLN26-014) and south (MLN26-015). MLN26-014 intersected anomalous radioactivity in the upper basement within a 0.5 metre strongly altered interval. Elevated radioactivity was intersected in the lower sandstone by MLN26-015. 50 metres north of MLN26-013, MLN26-016 intersected a 1.0 metre interval of anomalous radioactivity immediately below the unconformity associated with a broad zone of strong alteration and structure. Drilling determined the Cyclone trend is underlain by a package of graphitic and non-graphitic pelitic gneisses and quartzite over 100 metres in width. The full width of the mineralized structural corridor is unknown as additional prospective graphitic rocks may lie north and south of current drilling. Graphitic basement units host faulting and alteration. Basement faulting is best developed in the northernmost graphitic unit where MLN26-016 and -017 intersected metre- to decametre-scale fault zones, including a 35 metre interval that is enveloped by moderate to strong alteration. At the unconformity, the northern edge of this fault zone hosts radioactivity (MLN26-016) which remains open in several directions. 100 metres to the south, MLN26-013 and -014 intersected another graphitic fault zone which is enveloped by alteration and remains untested at the unconformity. Significant zones of sandstone structure and alteration are present throughout, and sandstone alteration patterns are similar to the Hurricane deposit where widespread bleached zones and distal silicified zones envelop broad desilicified zones cored by clay alteration. MLN26-013, -014, and -016 all intersected decametre-scale zones of sandstone faulting and alteration overlying the northern graphitic fault zone. Zones of faulting and alteration in the upper to middle sandstones of MLN26-013 and -016 suggest additional potential north of existing drilling. Multiple altered basement fault zones remain untested at the unconformity and down-dip. The Company and its Joint Venture partner, Denison Mines, will be finalizing summer plans in the coming weeks. The drill remains on site for rapid startup when drilling resumes this summer. Assays for all winter drill holes remain outstanding. MLN covers a portion of the Larocque Lake trend and is located 2.7 kilometres east of the Hurricane deposit. Hurricane is the world's highest-grade indicated uranium resource and was discovered and delineated for IsoEnergy Ltd. by current members of Cosa's team. The Larocque Lake trend also hosts the high-grade Larocque Lake Zone, Yelka Prospect, and Alligator Lake Zone. MLN contains the along-strike extension of basement geology underlying the Hurricane deposit (the Hurricane trend), as well as a parallel conductive trend to the south (the Cyclone trend). Cosa's winter 2026 drill program intersected several meters of basement hosted radioactivity within a broader zone of strong structure and alteration at the Cyclone trend. Following up these results is the primary objective for the remainder of 2026 at MLN. Cosa considers radioactivity anomalous when it (i) exceeds 350 cps measured with a Radiation Solutions RS-125 hand held spectrometer, (ii) is accompanied by structure and/or hydrothermal alteration consistent with Athabasca unconformity related uranium deposits, and (iii) spectrometric assay by RS-125 indicates uranium is the dominant source. All drill core is scanned with an RS-125 hand held spectrometer to check for radioactivity. Intervals of anomalous radioactivity are removed in 0.5 metre core lengths to an area of background radioactivity and average radioactivity for the 0.5 metre interval is measured. Cosa drill holes are also surveyed using an Imdex EZ Gamma (NOVAx) down hole probe to provide a continuous log of radioactivity at 0.1 metre intervals. Down hole probe results are compared to RS-125 results to verify the depth and strength of radioactive intervals and to assess for radioactivity though sections of lost core.

Cosa Resources Corp., Annual General Meeting, Jun 10, 2026 Cosa Resources Corp., Annual General Meeting, Jun 10, 2026. New Risk • Mar 24
New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of Canadian stocks, typically moving 17% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 56% per year over the past 5 years. Revenue is less than US$1m. Minor Risks Share price has been volatile over the past 3 months (17% average weekly change). Market cap is less than US$100m (CA$36.8m market cap, or US$26.7m).
