Kaizen Discovery Announces Positive Results from Diamond Drilling Program at Its 100%-Owned Pinaya Copper-Gold Project in Peru
Vancouver, March 1, 2022 - Eric Finlayson, Interim President and Chief Executive Officer of Kaizen Discovery Inc. (TSXV: KZD) otherwise ("Kaizen" or the "Company"), is pleased to announce positive results from recently completed exploration diamond drilling at the 100%-owned Pinaya Copper-Gold Project, located in the 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 3,046 metres of diamond drilling in 10 holes at the Pinaya Project, confirming the presence of shallow gold mineralization associated with base metal veins and skarn.
- The newly identified mineralization confirms that Pinaya is a large, multi-phase porphyry-related system with mineralization occurring over an area of at least 5km by 2.5km and with potential for new concealed porphyry copper-gold intrusions.
- Additional evidence of high sulfidation hypogene copper enrichment was intersected in retrograded skarn alteration affecting carbonate-bearing Puno Group conglomerates.
- Typhoon™ deep-penetration IP-resistivity equipment has been mobilized to the Pinaya camp. A survey covering the entire property will start in early March, with the aim of identifying anomalies potentially related to buried porphyry copper-gold mineralization. At 129km2, this will be the largest 3D Typhoon™ survey ever conducted.
"We are encouraged by the positive results received from this drilling program, which confirmed the large size of the Pinaya hydrothermal system and the potential for finding new porphyry mineralization," said Eric Finlayson, Interim President and CEO of Kaizen. "We will be commencing a Typhoon™ IP-resistivity survey in March to identify new porphyry targets for 2022 drilling."
2021-2022 diamond drill program at Pinaya identifies skarn and vein-related gold mineralization
The 2021-2022 diamond drill program comprised 3,046 metres of diamond drilling over 10 holes (see Figure 2 below). Targets were considered to be prospective for skarn and vein-related gold mineralization based on historical IP and geochemical data, combined with Kaizen's more recent geologic mapping and soil sampling (refer to Kaizen's news release dated March 24, 2021).
These targeting methodologies proved to be successful as a number of polymetallic veins were intersected in the northernmost drilled zone, more than 1km north of the area where the presently known Pinaya Mineral Resource is located. Additional veins were intersected 800m east of the resource.
The veins are interpreted to be of intermediate sulfidation affinity. They are sulfide-rich and emplaced into conglomerates and coarse-grained sandstones of the upper Puno Group sediments. They have thicknesses of up to several metres, with selvages of moderate hydrolytic alteration containing illite, chlorite, sericite, clays and sometimes adularia. Vein mineralogy may vary even within the same drill hole, evidencing a multiplicity of hydrothermal events. Veins normally carry pyrite, arsenopyrite, sphalerite, galena and chalcopyrite in variable proportions. They are also generally anomalous in antimony, tellurium and bismuth, elements characteristic of environments located distal to porphyry systems. Veins generally tend to diminish in intensity with depth.

A number of hydrous, retrograde skarn zones occasionally showing relict prograde skarn mineralogy were also intersected. These zones are mostly mineralized with zinc but sometimes also carry copper and anomalous gold. Locally, these zones have been strongly retrograded by acidic hydrothermal fluids which deposited high sulfidation copper minerals. This hypogene copper enrichment process was previously recognized within portions of the Pinaya Mineral Resource and is a particular characteristic present in giant porphyry copper deposits.

Typhoon™ Deep-Penetration IP-Resistivity Survey
The Company has mobilized a Typhoon™ geophysical transmitter to Pinaya and plans to commence a deeply-penetrating IP-resistivity survey over the entire property in early March. This survey should be a definitive test of deep porphyry potential and will be followed by drill testing of resulting targets later in 2022 (refer to Kaizen's news release dated August 9, 2021).

The Pinaya Mineral Resource
The Pinaya deposit is located within a 10 km-long zone marked by deep surface oxidation (irregularly extending up to 300 m below the surface) and reflecting disseminated sulphides in the Puno Group host rocks. 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% CuEq3,4 (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 million tonnes 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. 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 illegal miners on the property, 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 copper-gold intersections with grades significantly higher than in the rest of the Pinaya Mineral Resource, including 84 metres grading 1.11% Cu and 2.11 g/t Au in PDH-0395 and 103 metres grading 1.21% Cu and 1.28 g/t Au in PDH-0603. Second is the presence of pyrophyllite, dickite, bornite, 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.

ON BEHALF OF THE COMPANY
Eric Finlayson, Interim President and Chief Executive Officer
Kaizen's Chief Operating Officer, Mark Gibson, Pr.Sci.Nat. is a Qualified Person as defined under NI 43-101 who has reviewed, approved and verified the data disclosed, including the sampling, analytical and test data underlying the information or opinion related to the 2021-2022 diamond drill program at Pinaya, and is responsible for the scientific and technical information presented in this news release.
The Mineral Resources disclosed herein for the Pinaya Project are reported in the NI 43-101 technical report dated April 26, 2016, "Pinaya Gold-Copper Project Technical Report" prepared jointly by Brian Cole, P.Geo. and Ronald G. Simpson, P.Geo. (Geosim Services Inc.). Both Mr. Cole and Mr. Simpson are the Qualified Persons as defined under NI 43-101 for the Mineral Resource estimate and are independent of Kaizen.
Kaizen utilizes a comprehensive industry-standard QA/QC program. Drill core is sampled every 2 metres down hole along its length, and post-mineral cover and overburden is excluded from sampling. Sampled core is sawn lengthwise in two halves, and one half is sampled and shipped to an ISO-certified sample preparation laboratory. The other half of the core is stored in a secure facility for future assay verification if required. In the case of "field duplicate" samples, two quarter core samples for the same sample interval are sent for laboratory analysis, and the remaining half is stored in a secured facility. All samples were prepared at SGS SA's laboratory in Arequipa, Peru, and assayed at SGS SA's laboratory in Lima, Peru. SGS operates in accordance with ISO/IEC 17025. Gold is determined by 50 g fire assay with an AAS finish. An initial multi-element suite comprising copper, molybdenum, silver and additional elements is analyzed by four-acid digest with an ICP-ES or ICP-MS finish. Certified reference materials, blanks, and duplicates are inserted into the sample stream to monitor laboratory performance.
