The Igor Project includes the Callanquitas structure (the “Igor 4 concession”), where the PPX Mining has been conducting an underground operation through current mining partner, Proyectos La Patagonia. Ore has been mined and treated at a third-party plant.
The PPX Mining intends to build the CIL and flotation plant in Igor Project. The plant will process oxides and sulfides currently mined from high grade Callanquitas Mine, and other important satellite deposits that constitute part of the Project in the near future.
PPX has not declared commercial production at Mina Callanquitas. Nonetheless, increasing metal prices and mine productivity, coupled with superior toll milling contracts, have all contributed to the increasing revenue derived from operations at Mina Callanquitas. |

Summary:
The Igor property encompasses three exploration targets: Portachuelos, Domo, and Tesoros.
Field evidence suggests that the Igor project mineralization belongs to the epithermal type of gold-silver deposit.
The setting, alteration, and mineralization characteristics of the Callanquitas deposit are consistent with an intermediate to high-sulfidation epithermal system (Hedenquist et al., 2000). The deposit lacks the characteristic enargite, vuggy residual quartz, and alunite of the high-sulfidation systems and does not have the adularia diagnostic of the low-sulfidation systems.
The Igor project mineralization occurs within mineralized structural breccias that originally contained variable quantities of pyrite, arsenopyrite, and minor chalcopyrite. These sulfide minerals were subsequently strongly oxidized to significant depths.
Mineralization
Igor project mineralization occurs within four primary target areas: Callanquitas, Domo, Tesoros, and Portachuelos. Mineralization within the property often occurs at the transition zone from Chimú up into the Santa and Carhuaz rocks. There is a spatial association of dacite porphyry dikes emplaced within structural breccias with both structural and manto-style mineralization.
Callanquitas Veins
The Callanquitas veins (Callanquitas Este, Callanquitas Oeste and Cianuro) occur within a north-south striking zone of multiple, anastomosing to divergent faults that extend over a le ........
Mining Methods
- Cut & Fill
- Unconsolidated rockfill
Summary:
The mining method is a modified cut and fill. The development is mined first to access the mining area. Two raises are mined on both ends of the mining area. Then an ore drive is mined along the strike of the orebody. The first lift is mined by drilling and blasting up holes. The material is moved out of the drift via a slusher bucket and the raises. After the first lift is mined out the drift is filled by dropping waste fill down the raise and into the drift using the slusher bucket. This process is repeated until the mining area is mined out.
During 2022, Callanquitas produced ore with gold and silver content never seen before.
Summary:
Ore has been mined and treated at a third-party plant at a nominal 150 tonnes per day for several years.
In 2022, Callanquitas produced its highest production of gold equivalent ounces since the start of exploitation. This increase was possible due to the high silver grades.
