Harvest Minerals

Harvest Minerals is a potash and phosphate exploration and development company with projects located in Brazil.

The Group has three principal fertilizer projects – the Sergi Potash Project, the Capela Potash Project and the Arapua Fertilizer Project. The Company’s Brazilian subsidiary Triunfo Mineracao holds 100% of the mineral rights in respect of the Sergi Potash Project and the Capela Potash Project. The Company’s other Brazilian subsidiary Triunfo Fertilizantes holds 100% of the mineral rights in respect of the Arapua Fertilizer Project. The Group is currently undertaking various exploration and development activities on all three projects and, subject to capital availability, intends to undertake further exploratory analysis and drilling activities, where appropriate, over the course of the coming year on the assets to further prove up their potential.


Strategically located next to the only producing potash mine in Brazil, Vale’s Taquari-vassouras mine.

Existing plant means low CAPEX and OPEX

Recently completed JORC Inferred Mineral Resource modeling and Preliminary Economic Scope Study indicated a robust project.

JORC Inferred Mineral Resource of 62.0 Mt of Sylvinite grading 25.0% KCl.

Current Exploration Target of a further 28 to 38Mt at 22% to 28% KCl1

Initial drilling programme planned with the aim of upgrading the JORC Inferred Mineral

Resource to Indicated status.


Preliminary Economic Scoping Study completed

- Annual production of 600,000t of K60

- Initial mine life of 10.7 years with significant upside potential

- Mineable resource of 27.4 Mt of sylvinite

- Life of Mine average EBITDA of ~ US$140m per annum

- OPEX estimated at US$38.95/t ROM and plant costs assumed at US$45/t

- CAPEX estimated at US$ 427 million

- Pre-tax NPV 10 is $469m and an IRR 31.2%


  • The Arapua Fertiliser Project is located in the State of Minas Gerais, approximately 400 kilometres south east of the Brazilian capital city Brasilia and within one of the major agro-industrial centers of Brazil.

  • The Arapua Fertiliser Project is composed by eight mineral properties with exploration licenses granted and covering total area of 14,946 hectares. The project is divided into three blocks Arapua, Pindaibas and Maxixeblocks.

  • At the Arapua block, notable grades from recent grab samples ranged from 5% to 24% P2O5, over apatite-rich kamafugitic rocks.

  • At Pindaibas block, recent auger drilling returned values up to 14.8% P2O5.

  • The apatite-rich rocks are nearly horizontal and strongly weathered allowing to an easy mineable operation.

The fertilizer sector in Brazil is one of the fastest growing in the world. Over the last 15 years Brazil’s crop revenue has increased from US$23 billion to US$126 billion. Brazil is the world’s largest exporter of sugar, coffee and orange juice and the second largest exporter of soybeans. The country is currently the world’s fifth largest fertilizer consumer, and demand in Brazil is forecast to grow twice as fast as overall global demand until 2025. The country is one of the largest potash importers and the third largest potash consumer in the world, as well as the second largest world importer of phosphate.
