Recording date: 1st July 2026

Selkirk Copper Mines Inc. is advancing the restart of a previously producing copper-gold-silver operation, targeting first production by mid-2028. Positioned as a “restart story,” the project benefits from existing infrastructure, including a processing mill, camp facilities, and established site systems, significantly reducing the capital intensity and technical risks typically associated with new mine development. The company is focusing on incremental upgrades rather than rebuilding core infrastructure, while leveraging a substantial historical database to streamline engineering and planning.

Initial drilling results have reinforced confidence in the asset. A 175-hole Phase 1 program intersected economic-grade mineralisation in 87% of holes and identified two new mineral lenses near existing workings. These findings support the company’s broader strategy to develop an integrated mining operation combining open-pit and underground sources, with a roughly equal contribution in the early years and a gradual shift toward underground production over a projected 12-to-15-year mine life.

Selkirk is now progressing a 50,000-metre Phase 2 drill campaign focused on upgrading resources and advancing geotechnical studies. The program is ahead of schedule and will inform a feasibility study expected to begin in late 2026 and conclude by mid-2027. Updated economic and resource estimates are anticipated in July 2026.

Production planning targets approximately 30,000 tonnes of copper-equivalent output annually, supported by by-product gold and silver credits. To fund development, the company is pursuing non-dilutive options such as offtake agreements, project financing, and a potential silver stream, while avoiding the over-leveraging and permitting missteps that affected the previous operator.

With strong drilling results, existing infrastructure, and favorable metal price conditions, Selkirk aims to position the project as a lower-risk path to near-term copper production.

Interview with Philip Williams. Director & CEO of IsoEnergy Ltd.

Our previous interview: https://www.cruxinvestor.com/posts/isoenergy-ltd-tsxiso-sequential-build-out-anchored-by-us-uranium-restart-9432

Recording date: 1st July 2026

IsoEnergy has moved through a period of significant portfolio development, anchored by the completed acquisition of Toro Energy, encouraging exploration results in Saskatchewan, and continued technical work toward a potential production restart in Utah. Together, these developments position the company across three of the jurisdictions most favoured by uranium investors: Canada, the United States, and Australia.

The Toro acquisition brought the Wiluna project into IsoEnergy's portfolio, adding three near-surface deposits containing an estimated 75 million pounds of uranium. The project's shallow depth, from surface to approximately 10 metres, and its history of federal and state permitting make it a comparatively advanced addition. Management has outlined a six-to-twelve-month plan to update Wiluna's resource estimate and economic study to current Canadian reporting standards, alongside additional infill drilling intended to improve confidence in the resource.

In Saskatchewan, drilling at the Hurricane deposit's "south trend" produced results that exceeded internal expectations. An area previously modelled to contain grades of 1–1.5% uranium instead returned intersections above 10%, including a best result of 11.6%, with a follow-up hole grading 2.75% roughly 550 metres from the existing resource. Hurricane already ranks among the highest-grade uranium deposits globally, with an indicated resource of 48.6 million pounds at 34.5% uranium. The south trend results suggest that high-grade mineralisation may extend beyond the boundaries of the current resource model, and the company plans to continue testing this trend as its 20-hole summer drilling programme resumes.

In Utah, IsoEnergy is evaluating a restart of the Tony M mine. A 2,000-tonne bulk sample is being processed through a beneficiation technology that has shown it can remove 75% of material volume while retaining over 90% of contained uranium in initial testing. These results will feed into an updated economic study, expected before the end of 2026, which management has indicated will inform the ultimate restart decision.

Financially, IsoEnergy reports approximately $130 million in cash, providing flexibility to fund study work and exploration across all three jurisdictions without near-term reliance on external capital. NexGen Energy, an early investor in the company, holds approximately 28% of shares outstanding following dilution from the Toro transaction.

Management has characterised its overall approach as sequencing three potential mines according to their individual stages of readiness: Tony M as the nearest-term production candidate, Wiluna as a three-to-five-year development project, and Hurricane as a longer-dated asset dependent on further exploration and potential collaboration with neighbouring operators. This framing reflects a broader intent to reduce the binary risk associated with single-asset uranium developers by diversifying across geography and development stage.

For investors, the near-term catalysts to monitor include the Tony M economic study due by year-end 2026, further assay results from Hurricane's south trend as the summer programme continues, and progress toward updated resource and economic disclosures for Wiluna over the coming months.

Interview with Layton Croft, President & CEO, Carolina Rush

Our previous interview: https://www.cruxinvestor.com/posts/carolina-rush-tsxvrush-testing-deep-porphyry-potential-in-americas-first-gold-district-9470

Recording date: 1st July 2026

Carolina Rush has completed the first deep drilling program at its Brewer Gold-Copper project in South Carolina, confirming the presence of a copper-gold porphyry system beneath its historic near-surface gold mine. The program, consisting of three deep holes totaling 3,500 metres, marks a significant shift in the company’s exploration focus from shallow gold mineralisation to a larger, deeper target.

Results from hole 37 provided early indications of a porphyry system, including elevated copper levels, the presence of chalcopyrite, and characteristic quartz veining. More importantly, hole 38 delivered a breakthrough by intersecting copper-gold mineralisation beneath the lithocap for the first time. The hole returned multiple mineralised intervals, including 60 metres grading 681 ppm copper and 0.24 g/t gold within potassic alteration, a zone typically associated with the core of porphyry deposits.

A revised geological model, developed with porphyry expert Dr. Richard Sillitoe, suggests the system is tilted 20–30 degrees to the northwest rather than vertical. This interpretation implies that the mineralised core may lie at a shallower and more economically accessible depth than previously assumed.

The project is being advanced through an earn-in agreement with OceanaGold, which must invest US$8 million by the end of 2027 to earn a 50% stake. Carolina Rush remains the operator, while OceanaGold brings funding and regional infrastructure, including its nearby Haile gold mine.

With a defined near-surface resource of approximately 500,000 ounces of gold and growing evidence of deeper porphyry potential, Brewer represents a dual-opportunity asset. Assay results from the third hole are pending, and further drilling is planned to test the system along its interpreted northwest extension.
