Cerrado Gold Provides Update on the Las Calandrias Heap Leach Project at Its Minera Don Nicolas Mine in Argentina

• First production expected in second quarter 2023
• Highlights for the project include:
  • Project represents the first stage of the MDN growth program to deliver production rate of approximately 90,000 ounces per annum and All In Sustaining Costs ("AISC") below US$1,000 per ounce by 2024
  • Imminent growth to come from the development of heap leach operations at Las Calandrias and subsequently from the Martinetas area to process lower grade material
  • Las Calandrias first gold pour targeted for 2Q 2023
  • All engineering and testing completed, including Infill drilling, metallurgical testing and detailed design
  • Permitting is well advanced and all remaining approvals are expected during Q4 2022
  • Long-lead items have been ordered and construction to commence in Q4 2022 as planned

TORONTO, ON / ACCESSWIRE / October 18, 2022 / Cerrado Gold Inc. (TSX.V:CERT)(OTCQX:CRDOF) ("Cerrado" or the "Company") is pleased to provide an update on the progress of its development of the gold heap leach project at the Las Calandrias deposit at its Minera Don Nicolas Mine located in Santa Cruz, Argentina ("MDN"). The heap leach production strategy follows extensive review of the potential to utilize alternative production technologies at MDN with the aim of mining lower grade material not being delivered to the CIL plant.

As initially outlined in a press release dated February 9, 2022, the addition of heap leach operations at MDN is targeted to increase production rates to 90,000 ozs per annum from the 2022 rate of approximately 50,000 ozs with a reduction in AISC to below $1,000 ozs by 2024. Production growth and cost reduction is planned from the development of two heap leach operations, firstly at Las Calandrias and secondly at the Martinetas area.

The initial heap leach operation located at Las Calandrias is expected to commence production in Q2 2023. The Company has budgeted approximately US$25 million in development capital in 2022 and 2023 to construct the project. Financing of development is expected to be predominately from sources internal to Argentina.

The Company has completed all metallurgical works, geotechnical testing of the site and a detailed design of the crushing circuit and heap leach pad. License and permit submissions have been completed and main orders for crushing and construction of the pad have been placed or are in final negotiations. First material is expected to be loaded on the pad towards the end of Q1 2023, and the first gold production is expected in Q2 2023.

Mark Brennan, CEO and Co-Chairman commented "As we prepare to enter the Construction Phase at the Las Calandrias project, work to date has confirmed our expectations of the viability of using heap leach methodologies to more fully exploit the known resources at MDN as seen at neighbouring operations. As a result, we are now one step closer to delivering on the first stage of our production growth strategy at MDN by utilizing lower grade material that would otherwise not be processed. The Calandrias project is the first step in our goal to reach production rates of 90,000 ounces per annum with reduced AISC's at MDN by the end of 2023."

Production Plan

The Company has developed an internal mine plan to process lower grade and transitional material through a purpose-built heap leach facility at Las Calandrias. Extraction will be conducted via open pit mining at an estimated life of mine strip ratio of 0.75:1. A plan view of the current pit design is shown below in Figure 1.

Figure 1. Las Calandrias Pit Design

Metallurgical Testing

The company has completed all Metallurgical work at Las Calandrias and expects an average recovery of 67% from processing the Oxide and Transitional material. Recoveries in the primary zone are currently around 36% on average, with grades 30% higher than in the oxide and mixed zones. Testing to date has confirmed the following Au recovery rates for each ore type.

Plant Design

The Las Calandrias plant will be constructed to have a 2Mtpa capacity through a two-stage crushing process and pad design that will be built in stages. Water required for processing is currently expected to be sourced through third party purchases, however, ongoing hydrological drilling could add additional proprietary sources which would deliver a positive impact on operating costs and productions rates. A layout of the pad and ancillary infrastructure is shown below in Figure 2.

Las Calandrias Infill

During late 2021 and in 2022 MDN completed an infill drill program to support its understanding of the resource and to make a development decision. During this program a further 3,582m were drilled (1,320m DDH and 2,262m RC) in addition to the historical holes and assays.

A summary of the Total Exploration holes at the Las Calandrias property are presented below:

The company has received assays for all drilling to date at Las Calandrias. Drill hole locations and composites are provided in in Figure 3. and Tables 2. and 3. below.

Quality Assurance and Quality Control

Analytical work of MDN reported drill holes was carried out by Alex Stewart international, Argentina S.A. Labs (ASI). The facilities of the prep lab and assay lab are in San Julian, 184 Km from MDN mine operations. MDN sends out 10% of samples to check at ALS international labs (ALS) with the prep lab located in Mendoza and assay labs in Lima, Peru and Vancouver, Canada. In the main laboratory ASI (Mendoza), the samples are systematically analyzed for gold (ppm) and silver (ppm) by fire assay (Au4-50 + AgICP-AR-39) regarding the over limits with fire assay results greater than 10 ppm, a second assay is applied including gravimetric finishing (FA50GRAV), with respect to silver, analyzes greater than 200ppm are carried out by AgFA50GRAV.

ASI has routine quality control procedures which ensure that every batch of samples includes three sample repeats, two commercial standards and blanks. Cerrado used standard QA/QC procedures, when inserting reference standards and blanks, for the drilling program. The Reference material used are from CDN Resource Laboratories Ltd. Included in the batches following MDN internal protocols.

The historic database was verified by AGP in 2018. In addition, AGP verified the assay data provided by the company against the assay certificates provided by the laboratories: ALS (Mendoza) and ASi (Mendoza), as provided by New Dimension. AGP verified approximately 20% of New Dimension's database across all drill campaigns with any errors corrected prior to finalizing the drillhole database.

SRK undertook an assessment of the geological model in 2021 and made a number of recommendations that have since been adopted. MDN has reviewed and updated the information into the geological model with the latest drillhole information and using the recommendations of SRK.

Metallurgical testing work was carried out by National University of San Juan, Institute of Mining Investigations. MDN send half core samples for sample preparation to the lab. The laboratory has routine quality control procedures which ensure that testing is to Approved and recognised Standards.
