Lithospheric conductors reveal source regions of convergent margin mineral systems
The clean energy transition will require a vast increase in metal supply, yet discoveries of new mineral deposits are declining. Recently, several case studies have demonstrated links between electrical conductors imaged using magnetotelluric (MT) data and mineral deposits. Use of MT methods for exploration is therefore growing but the general applicability has not yet been tested. We look at spatial relationships between conductors and three deposit styles and find that volcanic hosted massive sulfide (VHMS) and copper porphyry deposits show weak to moderate correlations with conductors in the upper mantle. In contrast, orogenic gold deposits show strong correlations with mid-crustal conductors. These differences likely reflect differences in the way these deposits form, and suggest a metamorphic-fluid source for orogenic gold is significant. The resistivity signature can be preserved for hundreds of millions of years, and therefore MT can be a powerful tool for mineral exploration.
