Chilean Cobalt Corp. announced the execution of a Memorandum of Understanding with EcoBiome Metals, LLC, the parties have agreed to work together to comprehensively study and solve complex copper and cobalt extraction using sustainable and eco-friendly bio-solutions derived from EcoBiome Metals. The execution of this MOU follows successful initial bioleaching test work in 2023 performed by EcoBiome at their facility in Houston, Texas.

EcoBiome applied their patented Cultured Copper and Cultured Cobalt microbes to several tailings and waste rock samples from the La Cobaltera project area. The end result in each of the samples was a successful addition of highly functional and effective microbes, which accelerated the cycling and extraction of copper and cobalt metals through an organic and sustainable biological process. Based on the initial successful laboratory test work, C3 and EcoBiome have elected to formalize their investigative work and to outline an initial test program.

This program will broaden EcoBiome's test work to include samples of ore from new greenfield areas of the La Cobaltera project. This area is where C3 has recently completed topographical and aeromagnetic surveys, and is currently designing a follow-up exploration plan to execute later this year. C3's La Cobaltera exploration program will focus on the north-northwest extensions of known brownfield copper and cobalt-copper oxide resources in the broader San Juan district.

Samples taken for this second round of testing will be sent to EcoBiome's facility in Texas and will be analyzed and processed using the company's newly patented EcoBiome Discovery Platform to assess the effectiveness of copper and cobalt bio-extraction using its novel and proprietary Cultured Copper and Cultured Cobalt biotechnology. Following this second round of test work, C3 and EcoBiome will then discuss mutual interest in pursuing pilot plant development plans, amongst other areas of cooperation. This follows on previous metallurgical work at La Cobaltera completed by C3, which included chemical and mineralogical characterization followed by column leach test work and bottle roll acid leach test work on the oxide and transition zone samples, and rougher flotation test work on the sulphide samples.

Evaluation of EcoBiome's bioleaching technology would reduce, or potentially eliminate the use of harsh, and often expensive, chemicals during the mining and extraction process. The benefits of applying EcoBiome microbe technology will enable the possible replacement of corrosive and deleterious chemicals with the application and introduction of Organic certified and highly effective biomining microbes for the selective targeting, cycling, and extraction of copper and cobalt from complex ores.
