RE:Initial Inferred Resource for Cañariaco Sur Copper-Gold

[ckwong]

Apology for my careless mistake. The 9B pound copper is for Caariaco Norte. Caariaco Sur adds 2B pound of copper to infeered.

Candente Copper Announces Initial Inferred Resource for Caariaco Sur Copper-Gold Porphyry & Updates Caariaco Norte Resource, Peru

Vancouver, British Columbia, January 28, 2022. Candente Copper Corp. (TSX:DNT, BVL:DNT) ("Candente Copper” or “Company”) is very pleased to announce that an Initial Inferred Mineral Resource has been estimated for the portion of the Caariaco Sur deposit drilled to date.  Additionally the mineral resource for Caariaco Norte has been updated for purposes of the 2022 Preliminary Economic Assessment (“PEA”) which is nearing completion.
Commenting on the results, President and CEO Joanne C. Freeze stated, “We are very pleased to be able to establish this initial Inferred Resource containing 2.2 billion pounds of copper and 1.2 million ounces of gold* in Caariaco Sur.  This deposit contains higher levels of gold and molybdenum than Caariaco Norte, minimal arsenic levels and mineralization that starts at surface.  Caariaco Sur has the potential to add significant value to the resources at Caariaco Norte, 2km to the northeast.  The Initial Caariaco Sur estimate is based on 15 drill holes on the eastern portion of a large geochemical anomaly which extends several hundred metres to the west and southwest.  Higher grade phyllic style copper-gold mineralization was intersected in the western-most hole drilled to date.   Future drilling is planned for the west and southwestern sides as well as the undrilled Quebrada Verde porphyry target 1.5km southwest of Caariaco Sur.”
Ms. Freeze further stated “We are very excited to be nearing completion of the 2022 PEA on Caariaco Norte with project optimizations including a smaller higher-grade starter project, a lower initial capex and opportunities to enhance ESG aspects.”

Notes to accompany Caariaco Sur Initial Inferred Resource table:

1. The Mineral Resources have an effective date of January 27, 2022.  The Qualified Person for the estimate is David Thomas of DKT Geosolutions Inc.
2. The Mineral Resources were estimated in accordance with the Canadian Institute of Mining and Metallurgy ("CIM") Definition Standards (2014) and the CIM "Estimation of Mineral Resources and Mineral Reserves Best Practice" (2019) guidelines;
3. A single 0.1% Cu grade shell domain was constructed using implicit modelling
4. Raw drill hole assays were composited to 15 m lengths broken at domain boundaries.
5. Capping of high grades was considered necessary and was completed on assays prior to compositing. Copper assays were capped to a 0.8% threshold and gold assays were capped at a threshold of 1 g/t.
6. Block grades for gold were estimated from the composites using ordinary kriging interpolation into 20 x 20 x 15 m blocks coded by the 0.1% Cu grade shell .
7. The mineral resource is reported above a 0.15% Cu cut-off grade. Additional cut-off grades are shown for sensitivity purposes only.
8. A dry bulk density of 2.5 g/cm3 was used for all material.
9. The Mineral Resources are reported within a constraining Lerchs Grossmann pit shell developed using Hexagon’s MinePlan 3D™ software using:
   1. A copper price of US$3.50/lb
   2. Mining cost of US$1.60/t;
   3. An combined processing, tailings management and G&A cost of US$6.52/t;
   4. 45 degree Pit slope angles;
   5. A copper process recovery of 88%. 
   6. Copper concentrate smelter terms: US$75/DMT TC, US$0.075/lb RC and 96.2% payable
   7. Estimated concentrate shipping costs of US$133.00/WMT of concentrate
10. Copper equivalent grades including contributions from gold, silver and molybdenum, were estimated using metal prices (copper US$3.50 /lb, gold US$1, 650 /oz, US$21.5 /oz and US$11.00/lb Mo), metal recoveries (copper 88%, gold 65%; silver 57% and molybdenum 60%) and smelter payables (copper 96.5%: gold 93%; silver 90% and molybdenum 100%). Copper grade equivalent calculation: Cu Eq% = Cu % + ((Au grade x Au price x Au recovery x Au smelter payable%) + (Ag grade x Ag price x Ag recovery x Ag smelter payable%)+ (Mo grade x Mo price x Mo recovery x Mo smelter payable%))/(22.0462 x Cu price x 31.1035 g/t x Cu recovery x Cu smelter payable%).
11. There is no metallurgical testwork on Caariaco Sur at this time – Caariaco Norte average recoveries have been applied for LG shell generation and Copper equivalent estimations.
12. All figures are rounded to reflect the relative accuracy of the estimate. Totals may not sum due to rounding as required by reporting guidelines.
13. The contained metal figures shown are in situ.  No assurance can be given that the estimated quantities will be produced.
14. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

This Caariaco Sur estimate is based on 15 drill holes as well as geology, geochemistry and a review of the deposit lithology, alteration and specific gravities.
In addition, the Caariaco Norte Mineral Resource Estimate (previously reported on Nov 1, 2010) has been updated by David Thomas, P.Geo., of DKT Geosolutions Inc. and Jay Melnyk, P.Eng. Principal Mining Engineer at AGP Mining Consultants Inc.  The 0.15% Cu applied cut-off represents an approximate breakeven cut-off, based on parameters developed during the nearly completed 2022 Canariaco Norte PEA study.  Those results will be available shortly.

CAUTIONARY NOTE TO U.S. INVESTORS
We advise U.S. investors that this news release uses terms that are not recognized by the United States Securities and Exchange Commission ("SEC"), including "mineral resources", "measured resources", "indicated resources" and "inferred resources". The estimation of measured and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that mineral resources in these categories will be converted to reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. U.S. investors are cautioned not to assume that estimates of inferred mineral resources exist, are economically mineable, or will be upgraded into measured or indicated mineral resources. U.S. investors are cautioned not to assume that mineral resources in any of these categories will be converted into reserves.
