Highlights

  • Maiden Inferred Resource totals 7.23Mt at 102g/t Ga₂O₃ and 538ppm TREO.
  • Mineralisation remains open along strike and depth, indicating expansion potential.
  • Metallurgical testing progressing to support concentrate production for western markets.

Nimy Resources Ltd (ASX:NIM) has announced a maiden JORC (2012) Inferred Mineral Resource for gallium and rare earth elements (REE) at its Block 3 discovery within the Mons Project in Western Australia.

The Block 3 resource is estimated at 7.23 million tonnes (Mt) grading 102 grams per tonne (g/t) gallium trioxide (Ga₂O₃) and 538 parts per million (ppm) Total Rare Earth Oxides (TREO), containing 740 tonnes of Ga₂O₃ and 3,890 tonnes of TREO. The resource estimate applies a 70g/t Ga₂O₃ cut-off and is limited to oxide and transition zones to a depth of approximately 100 metres.

Exploration Targets and Growth Potential

Five new Ga₂O₃ exploration targets and one rare earth oxide (REO) exploration target have been identified by SRK Consulting within the Block 3 project area. These targets represent conceptual estimates ranging from 4Mt to 26Mt at grades between 70g/t and 100g/t Ga₂O₃, while TREO targets range from 18Mt to 74Mt at grades of 470–810ppm TREO.

Nimy Resources also identified additional prospects with gallium and REE potential across the Mons Project, including Masson, Thompson, and Vera’s targets, based on geophysical and geochemical surveys.

A surface soil sampling program and airborne magnetic survey are underway across an extended 30km² area surrounding Block 3 to further define mineralised zones.

Metallurgical Studies Underway

Preliminary metallurgical test work on Block 3 reverse circulation samples conducted at Curtin University indicates that gallium-rich minerals can be effectively processed under mild acid leaching conditions. The company is developing a flow sheet aimed at efficient separation and recovery of gallium and associated metals.

Strategic Importance Amid Global Supply Shifts

The Mons Project, located about 370km northeast of Perth, gains significance following China’s 2023 export ban on gallium and several critical metals. Gallium is classified as a critical mineral by Australia, the USA, the EU, Japan, and South Korea due to its applications in semiconductors, defence, telecommunications, and renewable energy technologies.

Nimy Resources has previously signed a non-binding memorandum of understanding (MOU) with U.S.-based M2i Global for future gallium supply. The announcement also follows the 2025 U.S.–Australia critical minerals agreement, which earmarks over AUD 8.5 billion in funding for priority projects, including gallium and rare earth developments.
