(Sharecast News) - Bradda Head Lithium has reported encouraging preliminary results from a mineralogical ore sorting study at its San Domingo project in Arizona on Tuesday, highlighting potential for reduced operating costs and enhanced project sustainability.
The AIM-traded firm said the study, conducted on core samples from 2023 drilling and supervised by ABH Engineering, suggested that the spodumene ore is amenable to particle sorting techniques.
It said the bench-scale findings indicated the potential to produce a direct shipping spodumene concentrate in-country through the efficient separation of wall rock and waste material.
The waste stream was found to contain virtually no lithium and could be sold as aggregate for local infrastructure use.
An intermediate lithium-bearing product was expected to be stockpiled for future processing.
The company said the results opened the door to lower water usage and improved environmental performance, while also offering economic benefits during construction and operation.
Based on the findings, Bradda Head said it was planning to proceed with a second phase of testing using a larger bulk sample and will assess options for economic optimisation, including resource cut-off adjustments and potential stockpiling strategies.
"Bradda Head is keen to move as quickly as possible to operational mode on its San Domingo pegmatite project in Arizona, leveraging the determination of the US government to develop domestic production of strategic minerals including lithium," said executive chairman Ian Stalker.
"This was most recently demonstrated with the presidential executive order issued on the 20 March, that clearly denotes benefits for junior miners such as Bradda.
"To this end, these mineral processing test results are positive indications of the opportunity for potentially producing a saleable, intermediate concentrate product that can be directly shipped."
Stalker said it would also be expected to greatly reduce potential upfront capex costs and permitting demands.
"Integrating mineral sorting early in the process can increase the grade, reduce the amount of mining equipment, infrastructure, and time to produce a saleable product.
"The results build on the previously announced study that also highlighted the opportunity for the production of a saleable lithium 6.0% and/or lithium 5.5% concentrate product via a gravity process route, again at minimum capex demand and potential low operating costs."
The further benefit, unveiled by the results, of producing a lower grade "ore sorted" concentrate was the minimum usage of water, Ian Stalker added.
"Bradda head continues to push ahead with its San Domingo pegmatite project in Arizona, not only to benefit from the ongoing 'America first' approach to strategic minerals supply in country, but also to be in a position to be operationally ready when the uptick comes in the lithium market in general."
At 1007 GMT, shares in Bradda Head Lithium were up 8.7% at 1.25p.
