Distance Squared interpolation runs were employed to estimate Cu, Zn, Pb, Ag and Au grades within domains into a subblocked model (parent block size of 25mE x 25mN x 10mRL). High grade restrictions were applied. Tonnage factors were applied to blocks by a regression formula between dry bulk density and the total estimated Fe+Zn+Pb+Cu grade.

Iron is essential for sustaining life, as its ability to cycle between multiple oxidation states is critical for catalyzing chemical transformations in biological systems. However, without proper regulation, this same redox capacity can trigger oxidative stress events that contribute to aging along with diseases ranging from cancer to cardiovascular and neurodegenerative disorders.
