Executive Summary: Key Legal and Evidentiary Issues

• Central dispute concerned whether the Area of Interest (AOI) clause in section 6.1 of the 2004 West Athabasca Option Agreement continued to bind the parties after UEX exercised its option and the Option Period ended on December 31, 2007.
• Interpretation of the Option Agreement’s text, especially sections 2.4, 2.6 and the definition of “Mineral Disposition,” was critical to determining if the AOI applied to later joint ventures and post-2007 mineral dispositions.
• The Court had to decide if summary judgment was appropriate on a pure question of contractual interpretation, despite UEX’s arguments about conflicting affidavit evidence, industry context, and the need for viva voce testimony.
• Both sides challenged the admissibility and quality of affidavit evidence (hearsay, opinion, subjective understandings), but the Court ultimately treated the evidentiary defects as mutual and non-dispositive.
• UEX relied heavily on subsequent conduct (2014–2020 dealings under the AOI) and raised equitable defences (estoppel, laches, acquiescence, waiver) to keep the AOI alive, which the Court rejected as a basis to “revive” an expired clause.
• The judge concluded that the plain language of the agreement limited the AOI to the Option Period, such that Orano’s later mineral dispositions in the AOI area are not subject to the Option Agreement, and granted declaratory relief accordingly.

Facts of the case

Orano Canada Inc., a long-standing uranium exploration, mining and milling company operating primarily in northern Saskatchewan, held mineral dispositions in several West Athabasca Basin projects, including Shea Creek, Douglas River, Erica, Alexandra, Laurie, Nakita, Uhrich and Mirror River. In the early 2000s, these projects were at varying stages of exploration, mostly at an early stage, and Orano sought an investment partner to share the substantial cost, risk and potential return involved in uranium exploration. UEX Corporation, a publicly traded uranium exploration company formed in 2001, entered negotiations with Orano in late 2003 and early 2004 for a potential investment in these West Athabasca projects. On March 5, 2004, the parties executed a letter agreement setting out the basic terms of an option that would allow UEX to earn up to a 49% interest in the projects by expending $30 million over 11 years. Following extensive negotiations and drafting, the parties executed the formal West Athabasca Option Agreement on November 10, 2004, but made it effective as of March 5, 2004. Under this agreement, UEX could acquire an interest in the defined mineral dispositions by funding exploration work, and upon satisfying its funding obligations, the parties would shift to a joint venture structure for each project. By December 31, 2007, UEX had met all its funding obligations under the Option Agreement, thereby earning a 49% interest in the mineral dispositions. Orano transferred that interest to UEX shortly thereafter. At that point, the Option Period ended and the parties were expected to move into a joint venture stage under the framework contemplated by the option.

The option agreement and area of interest clause

A central feature of the Option Agreement was the Area of Interest, or AOI, clause found in section 6.1. This provision stated that as of the Effective Date but prior to the exercise of the option, the parties agreed to create an area of interest surrounding the defined mineral dispositions, as described in Schedule “D,” to enable them to jointly explore this buffer area in the manner outlined in Schedule “E.” The clause further provided that if at any time after the Effective Date either party acquired ownership of any mineral disposition within the Area of Interest, that additional mineral disposition would, subject to section 6.2, be subject to the Option Agreement as if it were one of the original mineral dispositions. The surrounding evidence indicated that AOI clauses are common in uranium exploration agreements, typically providing a one-to-two-kilometre buffer around existing claims so that any new claims in that buffer – often based on confidential geological information developed in the project – must be offered to the other party. This prevents a party from using joint exploration data to privately stake adjacent ground without giving the partner a chance to participate. The dispute in this case turned on whether this Option AOI survived beyond the Option Period and continued to apply to the parties’ relationship once UEX had exercised its option and the joint ventures were in effect.

Joint venture provisions and failed negotiations

The Option Agreement contemplated a clear transition from the option phase to joint ventures. Section 2.4 provided that upon UEX satisfying its funding obligations, the option would be deemed exercised and the agreement would become one for transfer and assignment of Orano’s earned interest to UEX as a tenant-in-common in the mineral dispositions, free of encumbrances other than a royalty. Section 2.6(a) then required the establishment of a joint venture for each project upon exercise of the option, with each party contributing its participating interest in the relevant mineral dispositions. Section 2.6(b) listed “principal terms” to govern each joint venture – addressing matters such as management committee, cost sharing, dilution, minimum programs and budgets, operatorship, disposition of product and rights of first refusal – and stated that until formal joint venture agreements were negotiated and executed, the joint ventures would be governed by these principal terms. Section 2.6(c) obligated the parties to negotiate and execute formal joint venture agreements incorporating both the principal terms and such other terms “typically contained in a joint venture agreement for uranium exploration, development and production” in Saskatchewan, with any disagreements to be resolved by arbitration. In practice, although negotiations for formal joint venture agreements began in 2008 and involved extensive back-and-forth drafting, they were never successfully concluded. Attempts continued sporadically until around 2011 and again later, but the parties remained at an impasse. The result was that the projects moved forward in an “interim” joint venture state, governed only by the principal terms referenced in section 2.6(b), with no finalized joint venture contract setting out comprehensive provisions such as an AOI tailored for the joint venture stage.

Subsequent conduct and emergence of the AOI controversy

In July 2014, Orano acquired two mineral claims and UEX acquired several others in the same region, triggering questions about whether these new acquisitions fell within the original Option AOI. UEX took the position that the AOI clause in section 6.1 still applied and captured these new claims. After a brief internal review, Orano initially accepted UEX’s position and conducted itself on the basis that the AOI continued to apply. From approximately 2014 to 2020, both parties operated as though the AOI remained in force, offering each other opportunities to participate in claims within the defined AOI. Orano’s senior management, however, eventually revisited the agreement and concluded that the AOI no longer applied once the Option Period ended in 2007 and the relationship shifted to joint ventures governed only by the principal terms. In September 2023, Orano wrote to UEX’s new President and CEO to state its position that the AOI clause had expired with the Option Period and requested a formal acknowledgment. UEX rejected that interpretation and maintained that the AOI remained in effect, including for later-acquired mineral dispositions. This clash over the ongoing effect of section 6.1 set the stage for Orano’s application for declaratory relief in the King’s Bench.

Summary judgment and evidentiary issues

Orano brought the matter forward as a summary judgment application, arguing that the dispute was a narrow question of contractual interpretation that could be resolved on the written record. It submitted that there were no genuine issues of material fact requiring a trial, that the record allowed the judge to make necessary factual findings, apply the law and do so in a proportionate, efficient manner. Orano also pointed to the discretionary power under The King’s Bench Act to grant declaratory relief on a real, live dispute where both parties have a genuine interest in the outcome. UEX opposed summary judgment, contending that the matter was ill-suited to this procedure. It argued that there were conflicting affidavits on surrounding circumstances and subsequent conduct, outstanding concerns about admissibility of evidence, a need to understand the technical uranium exploration context more fully, and reasons for the Court to hear witnesses directly and assess credibility in viva voce testimony. UEX highlighted several prior cases where courts declined to resolve disputes on summary judgment due to evidentiary conflicts and interpretive complexity. Both sides attacked each other’s affidavits. UEX complained that many of Orano’s affidavits were hearsay-based and failed to identify the sources of the information. Orano responded that the context made clear the information came from within the company. Orano in turn criticized UEX’s affidavits for containing subjective opinions and interpretations of the agreement rather than strictly admissible facts. The judge acknowledged these evidentiary imperfections on both sides, noting that it is rare to see “perfect” affidavits in a dispute stretching over more than 20 years. He ultimately held that both parties were effectively in the same position with respect to affidavit flaws and that none of the objections was serious enough to drive the outcome. He dismissed the applications to strike aspects of the evidence and proceeded on the basis that summary judgment was appropriate, concluding that the core issue was contractual interpretation – a matter well suited to resolution on the written record.

Contract interpretation and the AOI clause

On the merits, UEX emphasized modern principles of contractual interpretation anchored in the Supreme Court’s decision in Sattva, stressing that the court must determine the parties’ mutual intentions at the time of contracting by reading the text in light of the whole agreement, its purpose and commercial context. UEX argued that the Option Agreement served a dual purpose: governing both the option phase and, until formal joint venture agreements were executed, the interim joint ventures themselves. It contended that section 6.1 created the AOI during the Option Period but did not expressly terminate that AOI upon exercise of the option, and that the second sentence (“if at any time after the Effective Date…”) contained no end date. UEX also focused on the definition of “Mineral Disposition,” which includes both the listed claims and, subject to section 6.2, “any new mineral dispositions that may be acquired in the Area of Interest by either party” and certain substituted or replacement claims obtained by the “Owner” during the Option Period. In UEX’s reading, only the latter substituted-or-replacement claims were limited to acquisitions during the Option Period; the new dispositions acquired in the AOI by either party were not temporally restricted and therefore remained subject to the AOI regime throughout the life of the relationship until superseded by specific AOI provisions in future joint venture agreements or project abandonment. Orano advanced a much more straightforward reading. It argued that the Option Agreement expressly defined the “Option Period” as running from the Effective Date to the exercise, abandonment or termination of the option, which the parties agreed ended on December 31, 2007. It maintained that section 6.1, properly read, created an AOI “as of the Effective Date but prior to the exercise of the Option,” meaning the AOI applied only during the Option Period. Once the Option Period ended and joint ventures were established, the only terms governing the joint ventures were the principal terms in section 2.6(b). Those principal terms did not include any AOI, and the parties had left AOI questions for the joint venture agreements to negotiate later as “typical terms.” The judge accepted Orano’s interpretation. He found that the plain language of section 6.1 explicitly tied the AOI to the Option Period, and that when the Option Period expired on December 31, 2007 with UEX’s exercise of the option, the AOI clause also ceased to apply. He further agreed with Orano’s reading of the definition of “Mineral Disposition,” rejecting UEX’s attempt to carve that definition into distinct temporal regimes in a way that would keep the AOI alive indefinitely for certain new claims but not for others.

Subsequent conduct and equitable defences

UEX also relied on the parties’ subsequent conduct between 2014 and 2020, pointing out that both Orano and UEX had acted for years as though the AOI remained in effect, offering each other opportunities in newly staked ground within the AOI. Orano responded that a party’s mistaken interpretation or change of mind cannot transform an expired contractual clause into a live obligation, and that courts exist precisely to resolve such interpretive disagreements. The judge agreed with Orano on this point, holding that subsequent conduct of this kind does not “revive” a clause that, on proper interpretation, has expired. In the alternative, UEX argued that even if Orano’s interpretation of the AOI clause was correct, Orano’s claim for declaratory relief should be barred by equitable doctrines, including estoppel by election, estoppel by convention, estoppel by representation, laches, acquiescence and waiver. UEX’s theory was that Orano had, over approximately 16 years, relied upon and benefited from the AOI and induced UEX to do likewise, and thus could not now resile from that position. Orano replied that it was not seeking to impose any AOI-based obligations on UEX; rather, it was asking the Court to confirm that an AOI obligation no longer existed under the contract. It stressed that equity is a shield, not a sword, and cannot be used to rewrite the parties’ contract to reinstate obligations that no longer exist under its terms. The judge accepted Orano’s position and rejected UEX’s equitable defences. He found no legal basis to “revive” an expired AOI through estoppel or related doctrines, especially where UEX itself had not consistently complied with the AOI in more recent dealings yet sought to impose it perpetually on Orano.

Ruling and outcome

In conclusion, the Court held that this was an appropriate case for summary judgment and that the dispute could be resolved on the basis of contractual interpretation without a full trial. Applying the plain language of the Option Agreement, the Court found that section 6.1 created an Area of Interest that applied only during the Option Period, which ended on December 31, 2007, when UEX exercised its option. After that date, the parties’ relationship was governed by interim joint ventures based solely on the principal terms listed in section 2.6(b), which did not incorporate the Option AOI. The Court therefore declared that the rights and obligations of Orano and UEX under section 6 of the Option Agreement expired on December 31, 2007, and that any mineral disposition acquired by Orano in the AOI after that date is not subject to the Option Agreement. Orano Canada Inc., as the plaintiff, was thus the successful party, achieving the declaratory relief it sought. The judge did not award any specified damages or quantify costs in this decision, instead inviting the parties to attempt to agree on appropriate costs or return to the Court to argue the issue. As a result, no exact monetary amount for costs, damages or any other financial award can be determined from this judgment alone.
