Black Adder Yields Up to 9.7 g/t Gold as Mt Clement Exploration Accelerates

Exploration Program Launches with Strong Early Results

Marquee Resources Limited (ASX – MQR) has commenced a systematic exploration campaign across its Mt Clement Project in Western Australia, aiming to unlock the gold potential within its extensive tenement holdings. The initial phase has already yielded encouraging results, with rock chip sampling at the historic Black Adder Prospect returning high-grade gold assays up to 9.7 grams per tonne.

This early confirmation of gold mineralisation is significant given the limited and incomplete historical exploration at Black Adder, where previous operators did not conduct detailed follow-up or multi-element assays. Marquee’s targeted sampling focused on quartz veins and gossanous material, revealing not only elevated gold but also strong arsenic and antimony signatures, which are key pathfinders in polymetallic systems.

Broader Gold Potential Across Mt Clement

Beyond Black Adder, Marquee’s technical team has identified multiple priority gold targets across the Mt Clement tenement package through a comprehensive review of historical data, geological mapping, and geochemical analysis. These targets span several prospects including Hardey Junction, Lady Marian, Fairview, and Mt Edith, each representing different mineralisation styles such as Carlin-type disseminated gold, structurally controlled vein and breccia systems, and stratabound mineralisation within iron-rich formations.

The company plans to progress these targets through a structured exploration program in 2026, starting with desktop studies and reconnaissance sampling before advancing to more detailed fieldwork. This methodical approach aims to build a clearer picture of the gold distribution and its relationship with the known antimony resources in the area.

Strategic Importance of Antimony and Resource Update

Marquee’s Mt Clement Project is also notable for its antimony mineralisation, with an Inferred Mineral Resource Estimate at Eastern Hills. The Australian Government’s recent announcement prioritising antimony within its $1.2 billion Critical Minerals Strategic Reserve underscores the metal’s growing strategic importance. This development could provide additional momentum and support for projects like Mt Clement that can supply high-quality antimony domestically.

Marquee is preparing an updated antimony Mineral Resource Estimate scheduled for release in the first quarter of 2026, which will be closely watched by investors and industry observers. The coexistence of gold and antimony mineralisation enhances the project’s polymetallic appeal and optionality for future development.

Looking Ahead

While the rock chip sampling results are early-stage and selective, they provide a compelling rationale for continued exploration. The Mt Clement Project’s location near Black Cat Syndicate’s Paulsens gold mine and its position within the underexplored Ashburton Basin add further geological intrigue. Marquee’s systematic exploration strategy and integration of historical and new data position it well to unlock value from this polymetallic system.
