Elida is a newly discovered porphyry copper-molybdenum exploration project within a property composed of 28 mining concessions totaling 19,210 hectares that are 100% owned by Element 29 Resources. The property contains a large, 2 x 2 kilometre alteration system enclosing a cluster of porphyry centres that represent five distinct exploration targets. The Project is located in central Perú, approximately 85 kilometres inland from the Pacific coast at moderate elevations between 1,500 metres and 2,000 metres and close to transportation and power infrastructure, including a 45 mega-watt hydroelectric generation facility situated 15 kilometres from the project.
In 2021, Element 29 completed seven drill holes in Target 1 totalling 4,481 metres that intersected multiple, long intervals of Cu-Mo-Ag mineralization and traced mineralization to a depth greater than 900 metres. Mineralization remains open at depth. The remaining four large targets are untested. Under the current drill permit, the Company can elect to drill-test all identified targets.
Exploration planned in 2022 will be designed to test the unexplored segments of the Target 1 mineralized zone and further constrain limits of mineralization where drill holes are lacking. Initial drill testing of Targets 2 and 3 will also be planned. Also in 2022, preliminary metallurgical studies have been initiated to examine recovery and comminution characteristics of mineralization for use in preliminary economic studies.
Elida Mineral Resource Highlights
- Pit-constrained, Inferred Mineral Resource Estimate of 321.7 million tonnes grading 0.32% copper (for a total of 2.24 billion pounds of contained copper) plus 0.029% molybdenum and 2.6 g/t silver, using a 0.20% copper cut-off grade and low modeled strip ratio of 0.74:1 (waste: mineralized material).
- A near surface, higher-grade subset of the Mineral Resource consisting of 34.1 million inferred tonnes at 0.55% copper, 0.037% molybdenum, and 4.4 g/t silver (at a cut-off grade of 0.45% copper) has potential to be mined with minimal stripping in the initial years of mining.
- Significant molybdenum and silver grades have the potential to enhance the economics of the deposit, subject to metallurgical test work.

Notes:
- The effective date for the Mineral Resource is September 20, 2022.
- Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.
- The CIM definitions were followed for the classification of Inferred Mineral Resources. The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as an indicated Mineral Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.
- Mineral Resources are reported at a cut-off grade of 0.2 g/t Cu, using a US$/CAN$ exchange rate of 0.75 and constrained within an open pit shell optimized with the Lerchs-Grossman algorithm to constrain the Mineral Resources with the following estimated parameters: copper price of US$3.46/lb, US$2.00/t mining cost, US$5.00/t processing cost, US$1.40/t G+A, 87% copper recovery, and 45° pit slope.
- The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
