Ammaroo phosphate project secures key mineral leases

Ammaroo phosphate project secures key mineral leases

Verdant Minerals says it has been granted two key productive mineral leases for its Ammaroo Phosphate Project by the Northern Territory government. The company says that this significant milestone advances one of the world’s largest undeveloped phosphate resources, located about 220km southeast of Tennant Creek. Acting Chief Minister and Minister for Mining and Energy, Gerard Maley, stated, “This is a significant milestone in progressing a world-class resource project that will support jobs, drive investment, and strengthen the NT’s position as a leader in resource development.”

The project promises approximately 400 construction jobs and 250 operational jobs, driving local economic benefits and supporting global agricultural productivity. Verdant Minerals is nearing the final stages of securing its mining authorisation, which will enable construction to commence. Verdant Minerals Managing Director, Chris Tziolis, expressed appreciation for the NT Government’s support, emphasizing the project’s crucial role in regional economic growth.

Ammaroo is estimated to contain measured, indicated and inferred resources of more than one billion tonnes of phosphate ore (P2O5 ), making it Australia’s largest phosphate resource. It is expected to ultimately produce around 2 million t/a of phosphate concentrate. Further processing will yield 500,000 t/a of merchant-grade phosphoric acid (100% P2O5 ) and 200,000 t/a of ammonia, which will be used to produce around 1 million t/a of ammonium phosphate fertilisers such as di-ammonium phosphate and mono-ammonium phosphate.

Daewoo to build phosphoric acid plant

Daewoo Engineering & Construction has signed a $700 million framework agreement to build a fertilizer plant in Turkmenistan. The agreement was signed in Seoul with Turkmenistan's state-owned chemical firm, Turkmenhimiya, according to the Turkmen Ministry of Trade, Industry and Energy, noting the Korean firm was named the preferred bidder for the project in October. The project aims to construct a fertilizer plant that will extract phosphoric acid from phosphate rocks and process the substance into 300,000 t/a of annually in eastern Turkmenistan by 2029.

KMCJNC to fund new phosphate project in Egypt

Chinese phosphate and battery chemical producer Chuan Jin Nuo Chemical (KMCJNC) has announced a $265 million plan to build a plant in Egypt to reduce its raw material and export costs. The company will construct facilities in the North African country to produce a range of intermediates and finished products, it revealed in its recent first-quarter earnings report. The plant will have a threeyear construction timeline. Planned capacities for the site are 800,000 t/a of sulfuric acid and 300,000 t/a of ammonium phosphate per year. Other core products will include phosphoric acid and sodium fluorosilicate. At full capacity, the plant is expected to generate over $41 million in net profit, according to feasibility studies.
