Magnetic susceptibility – the measure of how much a material will become magnetized in a magnetic field – reflects the presence of magnetic minerals in surface and subsurface rock bodies.
Magnetic susceptibility differences can help identify structures and rock bodies that may control rare earth mineralization.

The presentation illustrates the initial structural interpretation and context for the Lopez and Santos Trends. Significant REE mineralization crops out in surface exposures corresponding to approximately 2.5 km length of the Lopez Trend.
Geological exploration work currently underway at THOR is directed toward the identification of structural and lithological features that control the distribution of the REE mineralization. The strong NNE-trending positive magnetic anomaly coincident with the Lopez Trend is a major feature under current investigation, along with a number of cross structures indicated in the detailed data.

Forthcoming drilling will test mineralization concepts developed from detailed surface geology and 3-dimensional magnetic data interpretation. Understanding of the controls and context of REE mineralization along the Lopez Trend is being extrapolated to develop further drill targets in the covered Santos Trend with similar orientation and magnetic signature.
The REE mineralization occurs primarily as the mineral monazite, a rare earth phosphate. The monazite is hosted in granitoid intrusive rocks of Precambrian age.
The mineralization appears to have both magmatic and late magmatic to hydrothermal components, which may manifest as both favored lithic bodies and favorable structural alignments.
