Alkane extends high-grade gold trend at Brunswick South

PERTH, Australia, July 13, 2026 (GLOBE NEWSWIRE) -- Alkane Resources Limited (ASX: ALK; TSX: ALK; OTCQX: ALKRY) (‘Alkane’ or ‘the Company’) is pleased to announce the latest exploration results for extension and infill drilling of the Brunswick South deposit, located 400m south of the previously mined Brunswick vein and 200m from planned underground access at its Costerfield Operation in central Victoria, Australia. Program Summary An additional 91 holes targeting the Brunswick South deposit have been drilled since Alkane’s previous update (ASX announcement 15 October 2025 titled ‘Costerfield Resource and Reserve Statement) Confidence in grade continuity has been supported by the drilling with the identification of a high antimony and gold grade connection between the recently discovered gold dominant zone at depth and the historical surface workings. Drilling is continuing to identify extensions to the deeper gold dominant zone (Kiwi zone) with recent geological interpretation indicating the setting for mineralisation is similar to that of the Youle deposit currently being mined.

Additionally, parallel veining has been intercepted approximately 200m to the west of Brunswick South with follow-up drilling scheduled to commence shortly. An updated Mineral Resource Estimation with initial Ore Reserve is due to be released later in the year.
