- June 4th, 2019

Horizonte Minerals has completed testwork on samples of limonite ore from its wholly-owned Vermelho nickel-cobalt project in Brazil.

Horizonte Minerals (TSX:HZM) has successfully completed testwork on samples of limonite ore from its wholly-owned Vermelho nickel-cobalt project in Brazil’s Pará state.

Highlights from the press release are as follows:

  • High purity product containing 21.8 percent cobalt, exceeding the reference grade used for sulphate pricing

  • Nickel sulphate produced as a solution ready for purification to final battery grade product.

  • The results confirm the suitability of the Pressure Acid Leach (PAL) process and subsequent purification stages for processing Vermelho limonite ore to produce high purity cobalt and nickel sulphate suitable to supply the EV battery markets;

  • Positive results from the test work to be integrated into the pre-feasibility study underway on the Vermelho project

  • The results follow test work earlier in the year which also showed that Vermelho saprolite ore is suitable for conventional processing at the Rotary Kiln Electric Furnace (RKEF) to be built at the company’s Araguaia ferronickel project.

Jeremy Martin, Horizonte Minerals CEO, commented:

“Producing high purity nickel and cobalt sulphate from the Vermelho project of suitable quality and grade for use in EV battery production is a major milestone in the development of the project. The Vermelho project is a value driver for the company, it is a high-grade scalable resource, with good infrastructure and has the potential to be fast tracked to development.”
