According to Eruobattery, the majority of the samples were selected from the main mineralized nickel sulphide intervals previously confirmed by geochemical assaying and the objective of the study was to determine the mineral abundances and high-level analysis of liberation characteristics of sulphide and gangue minerals to aid with future mineral testing programmes.
The mineral studies determined the predominant Ni-sulphide mineral to be pentlandite with very minor millerite and violarite. Silicate minerals, iron oxides and chromite contain relatively low nickel concentrations.
“We are encouraged by the mineral test results which confirm high-value nickel sulphide minerals as dominating asset in the Castriz deposit,” Roberto García Martínez, CEO of Eurobattery Minerals, said in the media brief. “Our attention will now turn to identifying ways to maximize the value of our discovery by identifying potential massive sulphide zones and assessing the optimal mineral processing option for recovering the sulphides.”
Castriz is part of the Corcel project, located in Galicia, northwest Spain, near the town of La Coruña. The rock types at Corcel are ultramafic and mafic layered intrusive rocks which are known to host Ni-Cu-Co ore deposits.
