Epithermal Au-Ag: Low Sulphidation, with inferred porphyry-Cu roots
Nine separate mineralized structural zones have been discovered on the Klaza property.

The MNGC comprises two clusters of gold-rich polymetallic veins: (1) the Klaza cluster (NW); and (2) the past-producing Brown-McDade cluster (SE). Both clusters form the intermediate sulfidation epithermal extensions of a central porphyry complex. The central porphyry complex located south of Klaza comprises the Kelly, Cyprus, and Rusk drilled prospects.
Porphyry-type mineralization and alteration (Stage 1): Four vein types localized to the Kelly zone are grouped together and these define the stage 1 event.
Epithermal-type mineralization and alteration (Stage 2): The stage 2 veins constitute the main-ore stage at Klaza and comprises three sub-stages with the mineralogy zoned laterally (on the deposit scale) with respect to the inferred heat source, thus from hotter (SE) to colder (NW).
Epithermal carbonate veins (Stage 3): Sulfides hosted in carbonate veins are minor contributors to the overall Ag–Pb–Zn budget of the ore system. This vein stage cuts stage 1 and stage 2 assemblages and occurs as breccia or narrow veins and vein swarms.
Cataclasis (Stage 4): Stage 4 is syn- to post-stage 3 and occurs in the form of extensive shearing and cataclasis along the composite-vein-hosting fault structure. Vein-hosting faults display evidence of post-mineral movement, such as clay-altered fault gouges on the margin of mineralized quartz veins.
