Cabral Gold Inc (TSX-V:CBR)’s Brazilian subsidiary has hired a firm to conduct metallurgical tests on near-surface gold-in-oxide saprolitic material from its Cuiú Cuiú project.
The company shipped samples of near-surface oxide blanket and saprolite mineralization from the MG and Central gold deposits to Testwork do Brasil for heap-leach testing, as well as engineering tests.
"We already know from previous metallurgical test work that the gold-in-oxide material is very amenable to heap-leach processing,” CEO Alan Carter said in a statement. “Material from the MG deposit returned 82% gold recoveries after 70 days.”
“The tests we announced today are designed to provide initial information regarding the gold-in-oxide heap leach recoveries from the Central gold deposit and further assessing the metallurgical recoveries of higher-grade gold-in-oxide material which grades 2 grams per ton gold from both the Central and MG deposits. This work is critical to further refining the design of the gold-recovery circuit which will form part of the prefeasibility study," he continued.
The follow-up leach and engineering tests on oxide mineralization are being conducted in parallel with an ongoing trial-mining prefeasibility study, the company said, which is examining the potential exploitation of near-surface oxide mineralization being conducted by Ausenco do Brasil Engenharia Ltda.
In addition to the metallurgical tests on the oxide gold mineralization, further metallurgical results are also pending on the underlying hard rock mineralized material and are expected to be available in the coming weeks, according to a statement.
Elsewhere, Cabral Gold announced that board members Derrick Weyrauch and Rod Cooper have resigned to focus on other business interests.
Cabral Gold is a junior resource company engaged in the identification, exploration and development of mineral properties, with a primary focus on gold properties located in Brazil. The company has a 100% interest in the Cuiú Cuiú gold district located in the Tapajós Region, within the state of Pará in northern Brazil.
