Toro Toro - Hydrothermal Alteration Interpretation Muscovite 95/98%tile Pyrophyllite 95/98%tile Jarosite +429000 E +432000 E Toro North Pyrophyllite + jarosite Pyrophyllite Toro 98%tile Muscovite +435000 E Jarosite +6771000 N Figure 18: Image showing apparent zonation of hydrothermal alteration in the Toro and Toro North tenement area (on true-color Sentinel 2 image), using the ASTER-derived mineral models for muscovite, pyrophyllite, chlorite and epidote and Sentinel 2 model for jarosite. Note that the scale of this image is the same as those scales illustrated for the other areas in this presentation. Zones of anomalous muscovite (98th %tile), pyrophyllite and jarosite lie along an inferred north-northwesterly- trending structural corridor (see next figure). Two major centres are indicated: a southern muscovite-dominant centre and a northern pyrophyllite-jarosite centre. This geometry is consistent with increasing proximity to a possible porphyry centre (heat-source) to the south. 98%tile Chlorite/ +6768000 N epidote 80% 1000 2000 3000 +429000 E +432000 E +435000 E 21 1
