Demand for antimony is rising as new technologies require specialized metals for modern industrial systems. Manufacturers use the element in semiconductors, flame retardants, batteries and military equipment. Consequently, governments and technology companies are paying closer attention to global supply.
Antimony also plays a role in energy storage systems and advanced electronics. Additionally, the metal is used in solar panels, ammunition and certain types of glass manufacturing. These industries continue expanding as countries invest in new infrastructure and defense capabilities.
However, the global antimony supply chain remains heavily concentrated. China produces and processes the majority of the world’s antimony. As a result, Western governments increasingly view the metal as a strategic resource.
Officials in the United States, Canada and Australia have taken steps to diversify supply. Policymakers are supporting domestic exploration and development projects. Furthermore, several governments have placed antimony on official critical minerals lists.
These policies aim to reduce reliance on overseas supply chains. Consequently, mining companies operating in politically stable jurisdictions are attracting greater investor attention.
Many deposits containing antimony also host gold or other metals. Historically, companies focused primarily on precious metals while treating antimony as a secondary component. However, the metal now carries greater strategic value.
Exploration companies are beginning to recognize this opportunity. Additionally, several junior miners are identifying antimony mineralization within projects originally targeted for gold or other commodities.
Consequently, some companies are repositioning their projects to include both precious metals and critical minerals. This approach allows them to participate in multiple commodity markets while expanding the potential value of their deposits.
Several publicly traded companies are now advancing projects containing both gold and antimony mineralization. The following companies illustrate how the sector is evolving as demand for critical minerals continues rising.
Larvotto Resources
Larvotto Resources (ASX: LRV) (OTCMKTS: LRVTF) is an Australian mining company developing antimony and gold deposits. The company is advancing its flagship Hillgrove Antimony-Gold Project in New South Wales.
Hillgrove sits about 25 kilometres east of Armidale in northern New South Wales. The region has a long mining history and strong infrastructure connections. Roads, rail links and nearby airports support industrial development in the district.
Historically, miners extracted gold and antimony there since the late nineteenth century. Consequently, the district became one of Australia’s better-known historic mining centres. Larvotto acquired the Hillgrove project in December 2023. The company quickly began preparing the historic site for a restart.
The deposit contains significant antimony and gold mineralization across several zones. Additionally, exploration programs continue identifying new mineralized areas within the broader system.
Larvotto plans to redevelop Hillgrove into a major producer of both metals. The company expects the mine to produce about 5,000 tonnes of antimony each year. The operation could also generate roughly 40,000 ounces of gold annually. Consequently, Hillgrove could become one of the largest antimony producers outside China.
Larvotto is targeting production in mid-2026. Meanwhile, crews are advancing underground development and upgrading processing infrastructure. Workers have already begun rehabilitation activities at the historic mine site. Furthermore, the workforce is expected to grow as development accelerates.
Recent company updates focus on progress toward restarting the mine. Management reports that underground development and plant refurbishment continue moving forward. Exploration drilling has also continued across the Hillgrove system. Additionally, recent results confirmed strong gold-antimony mineralization in multiple zones.

Felix Gold
Felix Gold (ASX: FXG) (OTCMKTS: FXGDF) is an Australian exploration company developing gold and antimony deposits in Alaska. The company is advancing projects across the Fairbanks Gold District in the state’s interior. Its flagship asset is the Treasure Creek project about 25 kilometres north of Fairbanks. The district sits within the prolific Tintina Gold Province.
Several large operations operate nearby, including the Fort Knox gold mine. Consequently, the region remains one of North America’s most productive gold belts. Felix controls a large land position across the district. Additionally, historic exploration has already identified extensive gold mineralization and several high-priority drill targets.
Treasure Creek contains both gold and antimony mineralization. As a result, the project represents a dual-commodity opportunity. Several historic workings previously produced antimony from the property. One operation, the Scrafford mine, produced about 2.4 million pounds of high-grade antimony ore.
Modern exploration confirms similar mineralization across the property. Additionally, stibnite-bearing veins host significant antimony alongside surrounding gold zones. Felix continues advancing Treasure Creek through exploration and development programs. Management is evaluating potential pathways for both gold production and antimony recovery.
Recent updates also focus on exploration progress at the NW Array target. Drilling and trenching returned encouraging gold and antimony results. The results confirmed a large mineralized system that remains open along strike. Furthermore, the mineralization also extends deeper below current drilling.

NevGold Corp
NevGold Corp (CVE: NAU) (OTCMKTS: NAUFF) (FRA: 5E50) is a Canadian exploration and development company focused on gold and antimony deposits. The company operates projects across Nevada and Idaho in the western United States.
Both regions host major historic gold discoveries. Consequently, they remain among the most active mining jurisdictions in North America. NevGold’s flagship asset is the Limousine Butte Project in eastern Nevada. The project lies within the prolific Carlin-type gold trend.
This geological belt hosts some of the largest gold mines in the world. Additionally, it continues attracting exploration investment across Nevada. Limousine Butte hosts significant oxide gold and antimony mineralization near surface. As a result, the project is drawing attention from investors tracking critical mineral supply.
NevGold also controls several additional exploration assets. These include the Cedar Wash gold project in Nevada. The company also holds the Nutmeg Mountain gold project in Idaho. In addition, NevGold owns the Zeus copper project in the same state.
Together these properties provide exposure to several metals. However, management continues focusing primarily on gold exploration. Recent drilling at Limousine Butte expanded the Bullet Zone discovery. Step-out drilling continues extending the mineralized footprint.
Early 2026 results included 12.42 grams per tonne gold equivalent over 3.1 metres. Consequently, the company believes the system could support a future resource estimate. NevGold is also evaluating historic leach pads at the project. These materials contain measurable antimony from earlier mining operations.
