Aguia Resources Limited has two well-advanced mining projects in southernmost Brazil: cathode green copper and organic phosphate. The company pleased to share more outstanding results from agronomic tests on wheat crops using organic phosphate fertiliser, Pampafos®, from Phosphate Project. Pampafos®, was applied to wheat crops on a private property in Tupaciretã, one of the most productive regions in the state Rio Grande do Sul (`RS' or `State').

Wheat production is vital to the State's economy with the amount of land under wheat in RS increasing by 15% over the past year alone. In previous tests, the performance of Pampafos® was close to that of the chemical fertilisers. In this trial however, the productivity of all treatments using Pampafos® was either equal to or exceeded that of the chemical fertiliser, Single Super Phosphate (`SSP').

Previous agronomical testing on corn and rice crops using Pampafos® have also returned excellent results. This is critical as rice, wheat, and corn are the three most consumed grains worldwide. Aguia's natural phosphate fertiliser, Pampafos®, has now been tested on the following Brazilian crops, soybean, rice, corn (maise), oats, pasture and wheat, with all tests returning good results.

In addition to the positive performance of Aguia's natural phosphate fertiliser in the agronomic efficiency tests applied to a range of key crops, growers will also have ongoing environmental benefits of improved soil quality. There is also a potential cost reduction compared to conventional chemical phosphate fertilisers. Following the development of Aguia's organic phosphate fertiliser, Pampafos®, agronomic efficiency tests were conducted on the wheat crop on a commercial farm located at Tupaciretã, RS.

The tests were conducted in partnership with Rural Sul Pesquisa e Consultoria Ltda, an agronomic consulting company focused on the northeast region of the State, where some of the most productive lands in the State are located. The tests were overseen by Integrar Gestão e Inovação Agropecuária (`Integrar'), a renowned independent agronomic consulting firm located in the State, Aguia retained to plan and supervise the program. The wheat was seeded, in a latosoil area, distinct from the previous testing areas where flat soil was used, during the winter season in early June 2022.

The nutrient sources were applied by launching in the field. The test consisted of four treatments positioned side by side, comprising a total area of 4 hectares with approximately 1 hectare for each treatment. In treatments T1, T2 and T3, distinct dosages of P2O5 with Pampafos® were applied.

Treatment T4 followed the usual farm management, applying the conventional phosphate fertiliser Single Super Phosphate (`SSP'). Wheat grain production was determined by harvesting each treatment area separately and weighing the grain to calculate the yield in kilograms per hectare (kg/ha). Treatment T1, where 200 kg/ha of P2O5 was applied through the application Pampafos®, returned the higher yield of all treatments with 2,153 kg/ha, followed by treatment T2 with the application of 100 kg/ha of P2O5 through Pampafos®, resulting in a yield of 2,010 kg/ha.

Treatments T1 and T2 productivities were 18% and 10% higher than treatment T4, respectively. Both treatments, T1 and T2, using Pampafos® surpassed the treatment with the conventional phosphate fertiliser (T4), where 80 kg/ha of P2O5 was applied using SSP and resulted in a yield of 1,822 kg/ha. In the treatment T3 with the application of Pampafos®, 50 kg/ha of P2O5 resulted in a productivity of 1,801 kg/ha.

These positive results demonstrate that the natural phosphate from Phosphate Project, Pampafos®, was effective in providing the macronutrient phosphorus to the plants.
