31 MARCH 2026
Red Mountain Mining Limited (ASX: RMX, US OTCQB: RMXFF, or “the Company”), a Critical Minerals
exploration and development company with an established portfolio in Tier-1 Mining Districts in the
United States and Australia, is pleased to provide the following summary of activities undertaken
during the three-month period ending 31 March 2026 (“the Quarter”). The Quarter saw significant
progress for the Company’s Armidale Antimony-Gold Project in NSW, Australia and further growth in
Red Mountain’s US critical metals project portfolio. The Company closed the quarter with ~$1.75m in
cash and subsequent to the end of the period, secured a strongly oversubscribed placement of $1.6m
in addition to a $1m standby funding facility. The Company is placed in well-funded position to
execute on its growth plan and strategy.
OPERATIONS
Armidale Antimony-Gold Project, NSW, Australia (RMX 100%)
Red Mountain’s Armidale Antimony-Gold Project encompasses 391km 2 of prospective ground within
the Southern New England Orogen (SNEO) in north-eastern NSW. The SNEO is recognised as
Australia’s premier antimony province and hosts Australia’s largest known antimony deposit, Larvotto
Resources’ (ASX: LRV; Market cap ~A$700 million) Hillgrove deposit. Antimony in the SNEO occurs in
hydrothermal quartz veins, breccias, and stockworks, often with associated gold and/or tungsten
mineralisation.
Red Mountain’s project area lies west of Hillgrove and covers part of the Peel Fault system, which has
recognised potential for orogenic gold and antimony mineralisation. Several known mineral
occurrences lie within EL9732, where historical small-scale shallow shafts and open pits, thought to
date from the early 1900s, have exploited stibnite and gold (Figure 1). Given the age of these workings,
the little exploration conducted since and the proximity of EL9732 to the Peel Fault, RMX believes
there is untested potential for antimony and gold within the tenement.
