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.

Grupa Azoty adds new sulphur fertilizer to its range

Grupa Azoty has launched DuoS® , a new nitrogen–sulphur fertilizer. Its formulation is based on ammonium sulphate, ammonium nitrate and anhydrite and includes two forms of nitrogen – nitrate and ammonium; two sulphur sources – ammonium sulphate and anhydrite; and calcium to support crop resilience and the quality of produce. The new nitrogen–sulphur fertilizer with added calcium is designed to improve nutrient use efficiency and reduce leaching and other nutrient losses. It is recommended for pre-sowing and top dressing on winter and spring cereals, winter rapeseed, sugar beet, potatoes, legumes, grassland, as well as vegetables and fruit crops. Grupa Azoty says it is introducing DuoS® in the current season as part of a strategy to develop its fertilizer business and focus on specialty products.
