Kaizen Discovery announces drilling results from Pinaya Copper-Gold Project

Published by , Editor
Global Mining Review,

Kaizen Discovery Inc. has recently announced the results from recent exploration diamond drilling at its 100%-owned Pinaya Copper-Gold Project. The Pinaya Project is located in the prolific Andahuaylas-Yauri Porphyry-Skarn Belt in southeastern Peru, which contains some of the world's largest recent copper mine developments.


  • Kaizen completed a total of 1946 m of diamond drilling in three holes at Pinaya, and all intersected anomalous levels of copper mineralisation in altered Puno Group sedimentary rocks without intersecting the causative porphyry intrusions.
  • Hole PDH-164, collared in an area of outcropping lithocap alteration at the Cerro Antaña target, returned evidence of hypogene enrichment-style mineralisation - a characteristic feature of giant porphyry copper deposits. In addition, the hole intersected a gold-enriched zone including 18 m grading 2.54 g/t gold at a depth of 406 m downhole.
  • The company has interpreted the existing Pinaya Mineral Resource to be a shallow apophysis above a large, unroofed porphyry system extending to depth. Historical shallow-penetrating geophysical surveys would suggest that this system is at least 6 m by 2 m in areal extent.
  • The next step at Pinaya involves the company’s majority shareholder, HPX TechCo Inc. (HPX) - a wholly-owned subsidiary of High Power Exploration Inc., bringing its TyphoonTM high-powered geophysical surveying system to Pinaya to outline the deep porphyry system.

"We are encouraged by the results received from this initial round of diamond drilling, which indicate the presence of a large unroofed porphyry system at Pinaya," commented Eric Finlayson, Kaizen's interim CEO. "We will now be bringing HPX's proprietary Typhoon™ surveying system to site, which will allow us to map the deep porphyry system and direct future drilling."

Zones of anomalous copper mineralisation in altered Puno Group sedimentary rocks

The 2020 drill programme focused on three priority areas: Pedro Dos Mil, Cerro Antaña and Viscachani. These areas were deemed to be prospective for copper-gold mineralisation based on interpretations from recent geological mapping and surface geochemical sampling by Kaizen's geologists. Additionally, historic shallow-penetrating geophysical surveys completed by a previous operator showed the presence of shallow (less than 300 m deep) Induced Polarisation (IP) chargeability anomalies in these areas.

Kaizen's 100%-owned Pinaya Copper-Gold Project

The Pinaya Project is located in the Andahuaylas-Yauri Porphyry-Skarn Belt in southeastern Peru. This Eocene-Oligocene aged belt hosts numerous productive copper-gold porphyry and skarn systems, including Las Bambas, Tintaya, Constancia, Haquira, and Antapaccay.


Approximately 46 500 m of drilling at Pinaya were completed by the previous project operator and largely focused on defining the current Mineral Resource. The Pinaya Mineral Resource comprises measured and indicated resources totalling 41.7 million y grading 0.63% copper equivalent grade (CuEq) (0.32% copper and 0.49 g/t gold) and containing 135 000 t of copper and 656 000 oz of gold, plus 40.2 million t of inferred resources grading 0.55% CuEq (0.36% copper and 0.30 g/t gold) and containing 145 000 t of copper and 388 000 oz of gold. Resources consist of skarn and porphyry-style mineralisation. Based on the results from the recent drill programme, Kaizen believes that the potential for shallow extensions of the current Pinaya Mineral Resource is low.

Historic drilling in the Pinaya Mineral Resource area intersected several significant copper-gold mineralised zones including 84 m grading 1.11% copper and 2.11 g/t gold in PDH-0391 and 103 m grading 1.21% copper and 1.28 g/t gold in PDH-0601.

The Pinaya deposit consists of skarn and porphyry-style mineralisation, which has been interpreted to be a shallow apophysis above a larger, unroofed porphyry copper system.
