Cabral Gold Inc.’s (TSXV: CBR) Brazilian subsidiary has engaged Testwork do Brasil to commence metallurgical tests on near-surface gold-in-oxide saprolitic material from the Cuiú Cuiú project in northern Brazil.
Additional samples of near-surface oxide blanket and saprolite mineralization from the MG and Central gold deposits have been shipped to Testwork for further heap-leach testing, as well as engineering tests. These tests follow a successful column-leach test completed using a composite oxide sample from MG in 2022 which had 82% gold recoveries after 70 days.
The follow-up leach and engineering tests on oxide mineralization are being conducted in parallel with an ongoing trial-mining Prefeasibility Study which is examining the potential exploitation of near-surface oxide mineralization being conducted by Ausenco do Brasil Engenharia Ltda.
“We already know from previous metallurgical test work that the gold-in-oxide material is very amenable to heap-leach processing,” President and CEO, Alan Carter, said.
“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 2.0 g/t 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.”
Previous column-leach test work conducted by Kappes Cassidy & Associates in Reno, Nevada on a composite sample of oxide material from the MG gold deposit at Cuiú Cuiú, returned gold recoveries of 82% after 70 days. Recoveries after 15 days were 70% and recoveries after 30 days were 78%.
Recalculated gold grades following the column test were significantly higher than those determined by numerous assays from the bulk composite prior to the test.
In addition to the metallurgical tests that have commenced 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.

About Cabral Gold Inc.
The company 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.
Two main gold deposits have so far been defined at the Cuiú Cuiú project which contains National Instrument 43-101 compliant Indicated resources of 21.6Mt @0.87g/t gold (604,000oz) and Inferred resources of 19.8Mt @0.84g/t gold (534,500oz).
The Tapajós Gold Province is the site of the largest gold rush in Brazil’s history producing an estimated 30 to 50 million ounces of placer gold between 1978 and 1995. Cuiú Cuiú was the largest area of placer workings in the Tapajós and produced an estimated 2Moz of placer gold historically.
