A2MP: Files Canyon Minim-Martap Valuation Challenge Over Bauxite Mine

• A2MP Investments is challenging the valuation of Canyon Resources, specifically concerning its primary asset, the Minim-Martap bauxite mine in Cameroon.
• The dispute stems from a takeover offer where A2MP's A$0.05 per share bid was deemed "neither fair nor reasonable" by Canyon's independent valuer, BDO Corporate Finance Australia.
• BDO's valuation placed Canyon shares between A$0.14 and A$0.446, with a preferred value of A$0.32.
• A key point of contention is that nearly 96% of BDO's A$737.1 million valuation for Canyon is attributed to Minim-Martap resources not included in a modeled production scenario.
• A2MP's takeover offer is scheduled to expire at 7 p.m. Sydney time on September 21, 2026, unless it is extended or withdrawn.

The heart of the disagreement lies in the fact that a substantial portion—nearly 96%—of BDO's A$737.1 million (approximately CFA299 billion) valuation for Canyon Resources is derived from Minim-Martap bauxite resources that are not incorporated into any modeled production scenario.

A significant challenge has been mounted by A2MP Investments against the valuation presented by Canyon Resources, a move directly impacting a proposed takeover offer. This dispute, formally lodged with Australian regulators on September 2, 2026, centers on A2MP's contention that the assumptions underpinning Canyon's valuation are flawed. The independent assessment, conducted by BDO Corporate Finance Australia, suggested a share value for Canyon ranging from A$0.14 to A$0.446, equivalent to approximately CFA57 to CFA181, with a preferred midpoint of A$0.32, or about CFA130.

In stark contrast to BDO's figures, A2MP has maintained its offer price at A$0.05 per share, which translates to roughly CFA20. This substantial discrepancy led BDO to conclude that A2MP's bid is "neither fair nor reasonable" for Canyon shareholders. The ongoing takeover offer is scheduled to conclude at 7 p.m. Sydney time on September 21, unless Canyon Resources opts to extend or withdraw it before the deadline.

At the core of this financial disagreement is the Minim-Martap bauxite mine, Canyon Resources' principal asset located in Cameroon. A2MP's criticism of BDO's valuation methodology specifically targets how the mine's resources contribute to Canyon's overall worth. The independent valuation firm assigned a total value of A$737.1 million, or approximately CFA299 billion, to Canyon.

However, a critical detail highlighted by A2MP is that a staggering A$707.1 million—representing about CFA286 billion—of this total valuation is derived from Minim-Martap resources that are explicitly *not* included within any modeled production scenario. This means that nearly 96% (specifically, 95.9%) of Canyon's valuation, as determined by BDO, relies on bauxite resources for which no production plan has been factored into the financial model, forming the crux of the A2MP Canyon Minim-Martap valuation challenge.

This high-stakes Australian takeover bid challenge underscores the complexities inherent in cross-border mining M&A, particularly when significant assets like the Minim-Martap bauxite mine are involved in a Cameroon mining M&A dispute. The divergence in valuations between the bidder and the target's independent advisor highlights the critical importance of robust and transparent asset valuation in such transactions. The ongoing nature of the offer, with its impending September 21 deadline, adds immediate pressure to the situation.

For legal professionals advising on acquisitions in the African mining sector, this case serves as a potent reminder to meticulously scrutinize valuation reports. Assumptions regarding unproven or unmodeled resources, as seen in the BDO Corporate Finance Australia valuation, can become major points of contention. The potential for challenges from either bidders or regulatory bodies necessitates a thorough understanding of the underlying data and methodologies used to determine asset worth.

The A2MP Canyon Minim-Martap valuation challenge is more than just an isolated corporate dispute; it exemplifies the broader issues surrounding the valuation of natural resource assets, especially those with significant future potential but unconfirmed production pathways. The fact that almost 96% of Canyon's valuation stems from resources outside a production scenario raises fundamental questions about the defensibility of such figures in a takeover context.

This situation emphasizes that asset valuation, particularly for mining projects, must be grounded in clear, verifiable production scenarios to withstand scrutiny. Without this, even independent valuations can be perceived as speculative, opening the door for challenges that can derail or significantly alter the terms of an acquisition. The outcome of this particular dispute could set a precedent for how unproven resources are factored into public company valuations during takeover bids in the Australian and broader international mining markets.

This case highlights the critical importance of robust and defensible asset valuation in M&A transactions, particularly for mining assets where future production scenarios are key. Lawyers advising on cross-border acquisitions in the African mining sector should scrutinize valuation reports for assumptions on unproven resources and be prepared for potential challenges from bidders or regulators.
