Thank you for the question. I will answer in English.
Biomining process technologies have been around for over 50 years. There have been over 300 commercial operations globally. Canada has yet to deploy a large-scale biomining process.
We're using naturally occurring bacteria as the catalyst to break down minerals. These are often found in mine waste deposits and have adapted to the particular conditions of a site. Rather than using heat or chemicals, we use bacteria to act as the catalyst to break down minerals, and then release those into solutions so we can recover them.
This is a tested technology, but it has not had the time to mature and be deployed at commercial scales in Canada. It is one of the ideal solutions to deploy for reprocessing tailings or low-grade materials that would be too costly to put back into a smelter or a large capex operation.
We're working very hard to accelerate this with our partners to have an additional tool or processing technology for various materials that could be deployed quite quickly.
