Antimony Project Acquired in Australia's Premier Province

Red Mountain Mining Limited (“RMX” or the “Company”) is pleased to announce the receipt of a Notice of Proposed Grant of Exploration Licence (relating to ELA6810) from the NSW Department of Primary Industries. The project encompasses 391km² of prospective ground within the Southern New England Orogen (SNEO) in northeastern New South Wales. The SNEO is recognised as Australia’s premier Antimony province (Figure 1). Antimony occurs in hydrothermal quartz veins, breccias and stockworks, often with associated gold and/or tungsten mineralisation.

HIGHLIGHTS

• Exploration Licence to be granted for a period of six years and covering a significant package of 391 km² of prospective ground within the Southern New England Orogen of NSW, Australia’s premier Antimony Province
• The tenement extends over an 85km strike extent of the Peel Fault System, a known mineralised structural corridor, and includes multiple known Antimony and Gold mineral occurrences
• The best reported historical results to date include 465ppm Sb and 0.224ppm Au
• Given limited previous exploration these historical sampling results represent a significant greenfield discovery opportunity for Antimony and Gold
• Antimony prices have surged to ~US$33,500 per metric ton* as of 21 November following China’s recent export ban on a wide range of Antimony products

The Hillgrove project (ASX: LRV) is approximately 20km east of Armidale, is Australia’s largest known Antimony deposit. The mine has recorded production of over 730,000 oz of gold and over 50,000 tonnes of Antimony and a remaining resource of 1.7Moz Au equivalent at a grade of 7.4g/t Au equivalent, including 90,000 tonnes of Antimony, with significant exploration upside¹.

Project Geology

The project lies approximately 100km west of Hillgrove and extends for 85km immediately west of the Peel Fault. The geology of the tenement is dominated by isoclinally folded Carboniferous metasediments of the Tamworth Belt (Figure 2), which is a forearc basinal package related to west-dipping subduction of oceanic crust beneath the Lachlan Orogen. Ultramafic melanges of the Great Serpentinite Belt, which outcrop along the Peel Fault, are considered to be remnants of this oceanic crust. The Peel Fault System has recognised world-class mineral potential, with over 400 known orogenic gold and base metal mineral occurrences along its over 400km strike extent, but is underexplored with less than 200 mostly shallow drillholes over its length, the majority of which are focused on discrete prospects.

Tamworth Belt metasediments within the project are cut by multiple splays off the Peel Fault, including the major Namoi Fault (Figure 2). Gold, Antimony and Tungsten mineralisation are associated with orogenic quartz-vein and stockwork systems hosted within the Peel Fault System. The tenement encompasses nine historical gold workings (a mixture of primary orogenic vein-style and deep alluvial workings); three vein- hosted Antimony occurrences with historical workings; and one vein-hosted tungsten occurrence.
