Blackstone Minerals Ltd has Ta Khoa nickel sulphide low CO2 view confirmed by independent LCA
Blackstone Minerals Ltd (ASX:BSX, OTCQX:BLSTF) welcomes confirmation in an independent Life Cycle Assessment (LCA) of its lowest life cycle carbon dioxide (CO2) view2) emissions from the Ta Khoa Project (TKP) in Vietnam.
The results support ongoing partnership and funding efforts by validating the TKP nickel sulphide production design as the pathway with the lowest CO life cycle.2 emissions versus emerging and existing NCM811 precursor cathode active material production pathways.
The Ta Khoa LCA study confirmed a result of 9.8 kg of CO2-equivalent per kg of precursor cathode active material (pCAM) from the project, which is significantly lower than existing production pathways in terms of global warming potential (GWP), with known opportunities to reduce even further to 6.3 kg of CO2-equivalent per kg pCAM.
Minimize the environmental footprint
Blackstone Chief Executive Scott Williamson said: “At Blackstone, we have the opportunity to incorporate best practices into our development strategy, start from scratch on our emissions targets and align with industry leaders.
“We want to lead the way through the electrification of our mining fleet, the study of green hydrogen technology, the use of renewable hydroelectricity and, above all, our interactions with local communities.
“The decision to undertake this assessment reflects Blackstone’s commitment to minimizing its environmental footprint through its design process and understanding the most impactful and efficient pathways to achieve this.”
Summary of GWP LCA Results
Zero emission objective
Minviro, who is also responsible for completing the LCA of Tesla in its 2021 Impact Report and other industry peers, has been appointed by Blackstone to lead an LCA on the production of precursor cathode active material from nickel-cobalt-manganese (NCM) (pCAM) to TKP.
The study, which was conducted in accordance with the requirements of ISO-14040:2006 and ISO-14044:2006, used data from published pre-feasibility studies for the Ta Khoa Downstream Refinery (TKR) project and the of nickel from Ta Khoa upstream (TKN). .
As part of the accreditation process, the ACV was independently reviewed by a panel of three industry experts. Chaired by Dr. Viktor Kouloumpis, the panel included a representative from the Nickel Institute’s public policy team and an independent nickel metallurgy consultant.
While the base case GWP result of 9.8 kg CO2-equivalent per kg pCAM is an excellent result, Blackstone is aiming for zero emissions and is evaluating options to further reduce Ta Khoa’s GWP.
Minviro Director Laurens Tijsseling said, “Integrating LCA into the design stages of projects that will deliver the essential products for the world’s decarbonized future enables environmentally informed decision-making.
“We are proud to have been able to work with Blackstone to uncover current drivers of their environmental impact, both highlighting the effect current efforts will have on reducing environmental impacts and simultaneously showing areas of interest for truly activate Mining Green. »
