Aguia Resources Ltd: Significant Phosphate Intersections from Surface at Joca Tavares Project in Southern Brazil
June 21, 2013 — (Source: Aguia Resources Ltd) — Summary
- Previous rock chip assay results of up to 12.5% P2O5 are now supported by excellent first pass results from shallow auger holes that include:
- 14.7 metres @10.8P2O5 from surface (hole ended in mineralisation)
- Includes 10.7 metres @ 12.7 % P2O5
- 6.4 metres @ 8.2% P2O5 from surface (hole ended in mineralisation)
- Includes 2.4 metres @ 12.6% P2O5
- 5.5 metres @ 7.7 P2O5 from surface (hole ended in mineralisation)
- Includes 3.5 metres @ 9.9% P2O5
- Programs of soil and rock chip sampling confirm mineralised carbonatite host rocks outcropping at surface over a large area in excess of 400 metres x 1,350 metres.
- Ground magnetic survey now completed with interpretation to assist follow up reverse circulation drill testing and resource definition
- Joca Tavares is located 41 kilometres east -south-east from Aguia’s Três Estrad as project.
- The projects show similarities to the carbonatite style hosted phosphate deposits mined by Vale within Brazil, including the Cajati (Reserve: 85.1 Mt @ 5.45% P2O5 ) operations.
- The Company holds an extensive land position in the region and believes Rio Grande do Sul has the potential to host a major new phosphate province in close proximity to infrastructure, primary agriculture customers and fertiliser blenders
Aguia Resources Limited (ASX: AGR) (“Aguia” or “Company”) is pleased to announce that the Company has received excellent initial results from the Joca Tavares project located in the state of Rio Grande do Sul in southern Brazil.
The Company has completed detailed programs of mapping, rock, soil and auger sampling to delineate the dimensions of the Joca Tavares carbonatite for follow up programs of drill testing.
To date 25 shallow auger drillholes on four 100 metre spaced lines have been completed. Assays from the first 3 holes have been received and returned significant intersections of phosphate mineralisation from surface at similar grades to the recent discovery at Três Estradas (Figure 1, Table 2).
Joca Tavares has not been previously drill tested and these early results indicate phosphate bearing carbonatite host rock is present over an extensive area. All the holes were drilled to refusal and mineralisation is open at depth.

Aguia’s Managing Director, Simon Taylor, said “We are extremely pleased with the initial results from Joca Tavares and in particular the shallow auger holes that have outlined the potential for shallow oxide phosphate mineralisation. Together with the JORC compliant resource identified nearby at Três Estradas we believe the projects located in Rio Grande do Sul have the potential to form a solid basis for future project development opportunities including a potential early start up and cash flow.”
Both the Três Estradas and Joca Tavares projects represent significant new phosphate discoveries with characteristics similar to existing producers in Brazil. Importantly, the grade and mineralogy is similar to that of other operating mines globally including Yara’s Siilinjärvi mine in Finland and Vale’s Cajati mine in Brazil, both of which produce a high quality concentrate from phosphate within carbonatite host rocks.

|Três Estradas (Aguia)||Brazil||292||4.30%||65-83%||31-36%3||Exploration / Development|

|2. Inferred resource calculated from 45% of potential target length|
The three southern States of Rio Grande do Sul, Santa Catarina and Paraná currently consume over 1 million tonnes P2O51 or almost 30% of Brazilian consumption, however there are currently no producing phosphate mines in the region.
The Três Estradas, Joca Tavares and other Aguia projects will be logistically advantaged to supply the region compared with phosphate mined in Minas Gerais and Goias and imports.
