Mining Method

The Igor Project includes the Callanquitas structure (the “Igor 4 concession”). The The PPX Mining Corp. entered into a commercial agreement with Patagonia, a Peruvian mining contractor, whereby the PPX Mining granted to Patagonia a rights to mine the Igor 4 concession for certain number of years.

Proyectos La Patagonia S.A.C. utilizes the proceeds from the sale of the mineralized material to advance underground development at Mina Callanquitas in order to facilitate the future expansion of the mining rate to 350 tonnes/day.

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.

Deposit Type

  • Epithermal
  • Vein / narrow vein
  • Breccia pipe / Stockwork
  • Porphyry


Summary:

Mineralization within the property often occurs at the transition zone from Chimú up into the Santa and Carhuez rocks. There is a spatial association of dacite porphyry dikes emplaced within structural breccias with both structural and manto-style mineralization.

The Callanquitas veins (Callanquitas Este, Callanquitas Oeste and Cianuro) occur within a north south striking zone of multiple, anastomosing to divergent faults that extends over a length of 2,400 meters.

Individual veins can be up to 1.5km long with thicknesses between 0.2 to 8.2m. The Callanquitas structures are open along strike to the south and north and also at depth. The Callanquitas mineralization is considered an intermediate-sulfidation type, consisting of mineralized structural breccias that originally contained variable quantities of pyrite, arsenopyrite, and minor chalcopyrite. These sulfide minerals were subsequently strongly oxidized to significant depths. The primary mineralized structures (Callanquitas Este and Oeste structures), are nearly vertical and steep westerly dips are common.

The structures cut through a sequence of sandstone, siltstone and quartzite. The silicified sandstone and quartzite units were more amenable to brecciation and therefore more favorable for migrating hydrothermal fluids and mineralization. The dacite intrusive rocks are generally argillically-altered and although the mineralized structures cut through the dacite, the general lack of brec ........


Mining Methods

  • Cut & Fill


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.


Crushing and Grinding


Processing


Summary:

The mine currently produces at a rate of approximately 140 tonnes/day with ore being processed at nearby toll milling facilities.

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.
