African Gold resource growth and completed acquisition

African Gold reported a 119% increase in the Blaffo Guetto inferred resource to 989,000 ounces at a 0.8 g/t cutoff in June 2025 while Oehlman was CEO. Montage confirmed its acquisition of African Gold completed on 29 April 2026. The resource estimate is not production and the transaction was a company and shareholder outcome; his individual contribution is not independently quantified.

Role overlaps event; causation unproven · His CEO role overlaps the resource update; the sources do not attribute the outcome or deal exclusively to him.

Brett Butlin

Executive Director / Chief Geologist

Current
Personal SuccessDocumented · Medium materiality

Documented Jabal Sayid exploration reporting

A 3 June 2009 Citadel announcement names Butlin as exploration manager and competent person for exploration results at Jabal Sayid. Sierra Nevada later described him as Citadel chief geologist involved in delineation. Equinox’s filed annual information form says it acquired Citadel in January 2011; Sierra Nevada’s 2024 quarterly instead describes a sale to Barrick in 2010. Barrick announced its proposed Equinox acquisition in April 2011. The precise transaction description in the later Sierra Nevada report is inconsistent with the Equinox chronology; this does not undermine the cited 2009 reporting role.

Individual involvement documented · The 2009 source directly names him as the person compiling and consenting to the results; it does not establish sole discovery or responsibility for the later transaction.
