Great find.
I think this is the report you are talking about:

From the Pan American Gold Fields filing:
DEPOSIT TYPES
There are three main deposit types that are considered relevant to the Cieneguita Property: epithermal vein, mesothermal vein and porphyry. These are briefly discussed below.
Epithermal
High sulphidation epithermal deposits occur as veins, vuggy breccias and sulphide replacements ranging from pods to massive lenses associated with high-level hydrothermal systems marked by acid-leached, advanced argillic and siliceous alteration. Metal associations in these deposits include variable amounts of precious (Au-Ag) and base (Cu-Pb-Zn) metals and variable gangue
mineralogies. Irregular deposit geometries are the result of host rock permeability and the orientation of ore-controlling structures. Multiple, crosscutting composite veins are common.
Recent research indicates that these deposits form in subaerial volcanic complexes or composite island arc volcanoes above degassing magma chambers. The deposits commonly contain multiple stages of mineralization, presumably related to periodic tectonism associated with increased intrusive activity and magmatic hydrothermal fluid generation (Panteleyev, 1991). The age of the deposits are commonly Tertiary to Quaternary, however, some deposits have been dated Mesozoic and/or Paleozoic in volcanic belts. The rare preservation of older deposits reflects rapid rates of erosion before burial of subaerial volcanoes in tectonically active arcs.
Rock types associated with epithermal deposits include a subaerial andesite-dacite-rhyodacite pyroclastics and flows as well as their subvolcanic intrusive equivalents. It is also thought that permeable intervolcanic sedimentary rocks can act as sites of mineralization. The country rock surrounding epithermal veins is commonly extensively altered even though the vein walls may be sharply defined. It is also not uncommon to find large, highly coloured supergene gossans covering epithermal ores.
