- Bacteria are among the best geochemists in
the world, and occupy niche environments. ‘Omics-based detectors of specific genes can be used as exploration tools.
- Consortia of particular bacteria can remove
multiple constituents of concern from mine- influenced water simultaneously.
- Mineral-binding peptides that discriminate
between chalcopyrite and enargite can selectively recover these minerals.
- Bacteria can remove metals from water in
remote mines located in cold climes.
- Microbial communities are resilient and
resist catastrophic disturbances making ecological recovery possible.

BRIMM RESEARCH THEMES
- Integrate geological, mining, metallurgical, environmental and
economic data to create an accurate spatial and geologically- based orebody model to maximize value while minimizing risk throughout the mining value chain.
- Combine information from exploration, extraction, processing,
and waste management to better understand key performance issues such as, energy consumption, grade, grindability, efficiency of separation, water retention and tailings reactivity.
- New approaches to core logging are needed to allow data
collected to be systematic and spatial. This requires the innovative use of tools and development of geometallurgy- specific logging methods.
- Enable innovation and development of new approaches to
handling, treating, and storing tailings and leaching residues that extracts maximum value from gangue heterogeneity and maximizes water recovery.

BRIMM RESEARCH THEMES
Exploration geochemical data is available deposit wide. Use of these date to estimate mineral abundance allows:
- Ore and gangue heterogeneity to be assessed
- Representative samples to be more easily identified so they
can better inform metallurgical testing
- Assessment of environmental reactivity of tailings as a
function of alteration style and ore type

pathway to carbon sequestration in tailings and potential offsets to GHG emissions to reduce carbon tax and improve environmental impact.
