William Lewis, P. Geo from Micon International Limited (“Micon”) in Toronto, Ontario. Was a qualified person in charge of estimating mineral resources.

The updated PEA envisions an optimized mining program for open pit mining and heap reach mining operations, with daily production of 8,000 metric tonnes (“mtpd”) for the first two years and remaining mine life. Increases to 15,000 mtpd (“LOM”).

PEA can be found on our profile ( and on the Sonoro website (

PEA highlights:

  • 5% discount on net present value before tax (“NPV”Five”) US $ 84.4 million
  • 74.9% pre-tax internal rate of return (“IRR”)
  • NPV after taxFive US $ 53.5 million
  • 45.6% post-tax IRR
  • The gold recovery rate is 74% and the silver recovery rate is 27%.
  • 7-year LOM with 344,500 ounces (“oz”) of gold equivalent (“AuEq”)
  • 45,000 ounces of AuEq LOM average annual production (1-7 years)
  • Annual production of 46,000 ounces of AuEq at 0.58 g / tAuEq in the first to third years
  • Initial capital investment costs of $ 26 million, including $ 3 million in reserves
  • Maintaining the cost of capital of US $ 7.4 million
  • cash(1) Cost USD $ 1,206 / oz AuEq
  • AISC(2) US $ 1,333 / oz AuEq
  • 2.2 year payback period

Note: All currencies are reported in US dollars. The parameters of the base case assume that gold is $ 1,750 / ounce and silver is $ 22 / ounce.
(1) Cash costs include mining, crushing, processing, analysis and management.
(2) All-in-sustain costs include cash costs, as well as sustain, refining, refurbishment costs, and 2% royalties.

Estimates of mineral resources
The updated PEA utilizes the mineral resource estimates contained in our first PEA dated October 29, 2021 and is based on our September 2018-April 2021 drilling campaign. ..

Readers find that the extent of these potential mineralizations is conceptual in nature and is based on a limited amount of exploration drilling and sampling outside the current resource pit shell. Please note that it is unclear whether the mineralization target will be portrayed as a mineral by further exploration.

Excavation data
The recent completion of an additional excavation of approximately 7,200 meters at Cerro Cariche is not included in the current mineral resource estimates. The new geological data will be included in the updated resource estimates to be submitted in the fall of 2022.

Since the resumption of drilling in November 2021, we have announced multiple high-grade interceptions and expansions of several known mineralization zones in the southwestern part of the property. The potential economic impact of updated resources on the proposed heap reach mining operation will be reviewed in further technical reports.

PEA overview
PEA is inherently preliminary and contains estimated resources that may be considered too speculative, so it cannot be classified as mineral reserves with economic considerations and is presented in PEA. It is uncertain whether the estimate will be realized.
