Golden Crown Bulk Sampling Yields 218 Ounces and AUD$835K in Doré Sales

Bulk Sampling Success at Golden Crown

Mt Malcolm Mines NL (ASX:M2M) has announced the successful completion of its bulk sampling excavation program at the Golden Crown Prospect, a key asset within its Malcolm Project in Western Australia. The program targeted ultra high-grade gold mineralisation zones, producing a cumulative 218 ounces (6,780 grams) of gold doré from 812 wet metric tonnes (WMT) of material processed via wet gravity recovery techniques.

This milestone not only validates the presence of significant coarse gold mineralisation but also demonstrates the effectiveness of the company’s gravity recovery processing methodology. In January alone, 95.54 ounces (2,972 grams) of gold doré were produced from 200 WMT of material, with gravity-recovered gold grades reaching up to 20.6 grams per tonne in select batches.

Economic Implications and Revenue Generation

The gold doré bars produced have been assayed by The Perth Mint, confirming gold purity levels between 85.6% and 94.5%. Sales of the doré to The Perth Mint have generated AUD$835,462 in revenue, underscoring the commercial viability of the bulk sampling results. Managing Director Trevor Dixon highlighted that the successful program, completed without any lost time injuries, strengthens confidence in the economic potential of Golden Crown.

With processing ongoing for remaining stockpiles, the company is poised to capitalise further on its high-grade material. The bulk sampling results align well with previous drilling data, confirming well-defined auriferous quartz veins within sheared intermediate and felsic volcanics, a geological setting conducive to further exploration and development.

Next Steps: Resource Estimation and Strategic Planning

Looking ahead, Mt Malcolm Mines plans to integrate the bulk sampling data into updated resource estimations, which will provide a more robust foundation for future mining decisions. The company is also evaluating monetisation options for stockpiled ore and preparing for additional drilling programs informed by insights gained during bulk sampling.

These steps are critical as Mt Malcolm aims to optimise mining strategies at Golden Crown, potentially unlocking further value from this historically rich gold region near Leonora. The company’s methodical approach to processing and exploration reflects a commitment to sustainable and efficient resource development.

Technical Approach and Regional Context

The gravity recovery process employed involves crushing material to fine sizes, sluicing, hydrocyclone separation, and Knelson concentrator use, ensuring effective recovery of coarse gold particles. This technique is well-suited to the Golden Crown mineralisation style and has been validated through consistent recovery rates.

Situated within the Malcolm Greenstone Belt, the Golden Crown Prospect benefits from a rich mining heritage and proximity to established operations such as Gwalia and King of the Hills. The prospect’s structural geology, featuring steeply dipping shear zones and quartz veining, supports the potential for further high-grade discoveries.
