Kaiser Reef Commences Development at A1 Gold Mine to Enhance High-Grade Gold Production

Strategic Insights

Jun 25, 2024 — 1 min read

Kaiser Reef (ASX:KAU) has initiated development of a decline to access additional high-grade mineralisation at its A1 Gold Mine in Victoria, Australia. The project aims to capitalize on the existing high-grade gold production as the operation transitions from the current remnant mining. The Nova mineralisation, situated below the remnant mining operations, has been defined by diamond drilling between 2020 and 2023, revealing an extension of grade in both known and newly discovered quartz reefs in a hydrothermally altered host dyke.

Key Takeaways:

Kaiser Reef has started development of a decline to access high-grade mineralisation at the Nova deposit within the A1 Gold Mine, in Victoria, Australia.
The operation aims to increase high-grade gold production as it transitions from current remnant mining.
Diamond drilling between 2020 and 2023 defined an extension of grade in both known and newly discovered quartz reefs in the host dyke.
The host dyke has been drilled 143m below the 23 Level and is open at depth.
Initial sampling from the Dukes Reef returned average grades of over 15 grams per tonne (g/t) gold.
Broken stockpile sampling returned grades of up to 49g/t, while the central portion of the quartz vein returned grades of up to 18.1g/t.
Kaiser Reef initiated development in May to gain access to the Dukes Reef, which is expected to contribute to the September quarter production.
The A1 Mine has a history of production, operating between 1861 and 1992, producing around 620,000 ounces of gold at an average grade of 25g/t.
Kaiser acquired the A1 Mine in January 2021 via the acquisition of Centennial Mining.

Statistics:

430m of the Dukes Reef remains open at depth.
Diamond drilling between 2020 and 2023 revealed an extension of grade in the host dyke.
143m of the host dyke was drilled below the 23 Level.
Initial sampling returned grades of over 15g/t gold.
Broken stockpile sampling returned grades of up to 49g/t.
The central portion of the quartz vein returned grades of up to 18.1g/t.
