Resistivity as measured by ground loop EM. A prominent, near vertical resistive feature is evident extending to depths of +1,200 m. The principal fault encountered in drilling marks the western margin of this feature. At a depth of about 350 m, there is a subtle shift in resistivity marking a likely lithologic transition (purple line), perhaps from volcanic rocks above to basement sedimentary rocks below. Irving’s interpreted boiling horizon is shown in yellow. Irving believes the area highlighted in white is the most prospective target for high-grade veins.
