Kaizen Discovery Provides Exploration Update for the Pinaya Copper-Gold Project in Peru
Planning underway for drilling of shallow gold targets
HPX's deep-penetration induced polarization survey to search for porphyry copper-gold mineralization
Vancouver, British Columbia--(Newsfile Corp. - March 24, 2021) - Kaizen Discovery Inc. (TSXV: KZD) (otherwise "Kaizen" or "the Company") is pleased to provide an exploration update for 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.
Highlights:
- Historic shallow-penetrating Induced Polarization ("IP") geophysical surveys highlight several shallow chargeability anomalies, coincident with gold and geochemical anomalies, over a 6 km long by 2 km wide zone. These have high potential for skarn and vein-related gold mineralization and are mostly untested by drilling.
- Kaizen is planning to test these gold targets with up to ten, 300 m diamond drill holes.
- Planning is also underway for an IP-resistivity survey using the proprietary deep-penetration Typhoon™ high-power transmitter system owned by parent company HPX TechCo Inc. ("HPX") - a wholly-owned subsidiary of High Power Exploration Inc., to trace the Pinaya Mineral Resource and shallow chargeability anomalies to depth, to identify deeper concealed mineralized bodies within the 10 km-long Pinaya hydrothermal system, and to explore beneath Miocene cover rocks west of the Mineral Resource.
"This planned program is an exciting new phase in the advancement of the Pinaya Project. The existing Pinaya Mineral Resource is only part of a much larger hydrothermal system, with plenty of scope for new discoveries," commented Eric Finlayson, Kaizen's interim Chief Executive Officer.
Planned 2021 Drill Program
Multiple untested shallow gold targets have been identified by Kaizen after reviewing historical geophysical and geochemical data, combined with Kaizen's more recent geologic mapping and soil re-sampling. Of the seven large chargeable features identified, only three have been partially drill tested in the past with encouraging results. The focus of exploration by previous operators was to define the current Pinaya Mineral Resource and much less on drill-testing regional exploration targets.
The first phase of the 2021 diamond drill plan at Pinaya will comprise up to 3,000 m of diamond drilling over 10 holes (~300 m each) across six of the seven shallow gold targets (see Figure 1 below). Strike extensions of mineralized cross structures in the area of the Pinaya Mineral Resource are also planned to be drilled.
Permitting of the drill holes is underway and the Company is considering available options to finance the exploration program.
Planned 2021 Typhoon™ Deep-Penetration IP-Resistivity Survey
As indicated previously (refer to Kaizen's news release dated July 7, 2020), an IP-resistivity survey using HPX's proprietary deep-penetration Typhoon™ high-power transmitter system is planned to trace the Pinaya Mineral Resource and shallow chargeability anomalies to depth, to identify deeper concealed bodies of mineralization within the 10 km-long Pinaya hydrothermal system and to explore beneath Miocene cover rocks to the west of the Puno Group host rock sequence. Subject to Typhoon™ availability, this survey could commence as early as May.
Background on Pinaya
The Pinaya copper-gold property is located in the Middle Eocene to Early Oligocene Andahuaylas-Yauri Belt, a significant porphyry copper province that hosts numerous productive copper porphyry and skarn systems including Las Bambas, Constancia and Antapaccay. Pinaya appears to be the southernmost and youngest of the deposits with an age of 28.5 Ma, almost 5 Ma younger than any other deposit within the belt. While most deposits within the Andahuaylas-Yauri Belt are gold-poor, informal gold mining has occurred intermittently at Pinaya and is focused on the area of mineralization known as the Gold Oxide Skarn Zone.
Pinaya occurs within a fold and thrust belt, with the deposit truncated on the western side by a fault that throws the deposit and its Early Oligocene Puno Group sedimentary host rocks against younger Miocene-age rocks. There is untested potential for mineralization to continue westwards beneath the Miocene cover. Geological evidence suggests that mineralization was emplaced during early stages of the fold and thrust deformation, with both porphyry intrusions and mineralization showing strong structural and stratigraphic controls.
The Pinaya Mineral Resource
The Pinaya deposit is located within a 10 km-long zone marked by deep surface oxidation (extending up to 300 m below the surface) and reflecting elevated sulphide contents in the Puno Group host rocks (see Figure 2). Kaizen interprets this to be the overall footprint of the Pinaya hydrothermal system within which numerous copper and gold deposits could potentially occur.
Drilling to date has identified a shallow Mineral Resource comprising Measured and Indicated Resources totalling 41.7 million tonnes grading 0.63% CuEq[1],2 (0.32% copper and 0.49 g/t gold) and containing 135,000 tonnes of copper and 656,000 ounces of gold, plus 40.2 Mt of Inferred Resources grading 0.55% CuEq (0.36% copper and 0.30 g/t gold) and containing 145,000 tonnes of copper and 388,000 ounces of gold. Mineral Resources are reported at cut‐off grades of 0.25 g/t Au for the GOSZ (Gold Oxide Skarn Zone) and 0.3% Cu Equivalent for the WPZ (Western Porphyry Zone) and NWPZ (Northwestern Porphyry Zone) zones. Note that Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
Mineralization remains open to depth and is of both porphyry and skarn styles, with the porphyry mineralization developed within and around sill-type porphyry intrusions. The skarn mineralization, which is the target of the informal miners, is developed within calcareous members of the Puno Group host sequence.
There are two significant features to note about the porphyry mineralization. First is the presence of several long, unusually high-grade copper-gold intersections. Historic drilling in the Pinaya Mineral Resource area intersected several significant copper-gold mineralized zones including 84 metres grading 1.11% Cu and 2.11 g/t Au in PDH-0392 and 103 metres grading 1.21% Cu and 1.28 g/t Au in PDH-0602. Second is the presence of pyrophyllite, dickite, bornite and enargite; and hypogene chalcocite and covellite. Taken together, these features suggest that hypogene enrichment has occurred, a hydrothermal process in which copper is upgraded in a deposit through the action of late acidic fluids. This process is a feature in porphyry copper systems such as Oyu Tolgoi in Mongolia and Resolution in Arizona.
It remains to be determined where the Pinaya porphyry sills and mineralizing fluids originated. It is notable that the original shallow Pebble porphyry copper-gold discovery in Alaska was also hosted by a sill and by tracking the sill eastward to depth, the giant Pebble East deposit was subsequently discovered.
Geophysical expression of mineralization
Historic geophysical surveys at Pinaya included a shallow-penetrating IP-resistivity survey, with a search depth of around 300 m. As this survey did not see through the deep oxidation layer, the IP chargeability response of the porphyry mineralization was muted. However, the Gold Oxide Skarn Zone mineralization, which was presumably more sulphide-rich, provided a much stronger chargeability response due to the presence of more abundant relict sulphides.
What is evident from the historic IP-resistivity data is that the strongest chargeability features, extending in combination over several kilometres, have not been properly tested by drilling. As with the Gold Oxide Skarn Zone mineralization, these anomalies presumably reflect sulphide-rich zones that have not been entirely oxidized near surface.
Geochemical expression of mineralization
The high-chargeability zones are coincident with elevated gold in soils and historic surface trench samples (up to 10 g/t Au) (see Figure 1 below), and with pathfinder element anomalies (principally arsenic and metals such as copper, bismuth and tellurium). The anomalies are structurally controlled and lie along major northwest-southeast and northeast-southwest trending features.
