Eagle Star Minerals Corp. (CVE:EGE) announced Thursday a new edition to its technical team with the appointment of metallurgical engineer Lino R. Freitas.
For more than 25 years, Freitas worked with Vale at their Centre of Technology developing processes for beneficiation and upgrading phosphate and potassium ores.
With over 37 published papers in specialized magazines, he is also the co-owner of 16 patents relating to the beneficiation processes.
In mining, beneficiation is a variety of processes used to extract ore and then separated into mineral and gangue, the former suitable for further processing or direct use.
Freitas joins the company as senior manager of technical services, after helping Eagle Star with chemical and metallurgical tests at the Canabrava block.
His duties will also include developing an optimal beneficiation process for the Canabrava phosphate on analysis of bulk sampling taken from the project area.
In addition, Freitas will be supervising the technological tests to be conducted on other Eagle Star properties, such as the Bomfim and the Samba agro-mineral projects in an effort to find the most efficient way to move these into production.
“We are incredibly fortunate to have Freitas join the Eagle Star team,” chief executive Eran Friedlander said in a statement.
“His vast knowledge of metallurgy and specific experience with phosphate will add considerable value to our projects and ultimately change the dynamics within the company as it moves closer to production.”
Eagle Star, over the past two years, has boosted its presence in Brazil and continues to concentrate on maximizing shareholder value by acquiring proven phosphate mineralization assets.
The Bomfim agro mineral project, located in the new phosphate belt of Brazil, covers 30,922 hectares across four claims with all exploration licenses and permits in place.
Eagle Star has conducted preliminary mapping and sampling work, and also plans to carry-out a scout drilling program of up to 2,600 metres with a 50 metre depth sometime this September.
Earlier this month, Eagle Star received “excellent” solubility and heavy fraction recovery results from its Canabrava mining block in Brazil.
The mining concession, which rests at the Ruth Agro mineral project, encompasses 40,678 hectares across 23 mineral claims.
The tests, aimed at defining chemical composition and solubility of mineral phases, were performed using three chip samples from rock types that compose the mineralized package.
Solubility tests in both hydrochloric and citric acids confirmed fluor-apatite is the main phosphorous-bearing mineral with solubility of phosphorus and calcium ranging from 87 to 96 per cent.
