First orebody intersected at Coringa mine development

Highlights
Mike Hodgson CEO said
“These initial results from Coringa represent a significant milestone achieved and excellent progress continuing at the project. Coringa has over 50,000 metres of drilling already complete, but this is the first exposure of the mineralisation by underground excavation. The underground development will be continued on this level to expose the other veins of the Serra ore body and will be followed up by on-lode development to gain further underground exposure as well as to extract a significant bulk sample for further testing. We feel the underground exposure will allow us to optimise the mining methodology currently being considered and the bulk sample will be used to undertake ore sorting testwork, using our facility 200km to the North at Palito. Coringa does appear to be amenable to ore-sorting and this would bring the prospect of reducing process costs and diminishing tailings required for filtration, a huge plus for the project.
“With a drilled resource of approximately 500,000 ounces, we will now develop through some of these ore zones. As this development continues, we will continue sampling and assessing the geometry of the orebodies as well as completing various studies. I am therefore looking forward to providing regular updates on this exciting Project during 2022.”
RESULTS
The Company commenced the main ramp into the Serra zone, July 2021. The ramp is a four metre high and four metre wide gallery, which has intersected the first of three veins which comprise the Serra Zone. The ramp has traversed the lode, perpendicular to strike. This development lies on the 320 metre level, approximately 50 vertical metres below the portal entrance. The ramp will continue to advance on the 320m level to the second and third lodes in the Serra Zone. As each lode is intersected, smaller three metre high and three metre wide ‘on-lode’ development will advance, following the veins along strike, allowing regular sampling and consequently significantly enhancing the understanding of the ore-body.
A smaller ramp has commenced off the main Serra ramp, rising up to level 340 metres, where once the veins are again intersected, a similar development design on each of the three lodes is planned. Over the next months the Company plans to undertake sufficient ramp and ore development at Serra Zone to assist with optimizing the mine methodology and securing a bulk sample.
Coringa permitting progress continues as planned. With the application for the installation license having been submitted in September 2021, the Company anticipates approval in late Q1/early Q2 2022, with construction planned to commence early Q3.
The Company has, over the past few months, been working with Icone Technology & Engineering to complete the detailed engineering design of the Coringa process plant. Icone are an established engineering firm within the Brazilian mining industry. Located in Minas Gerais state they have provided services to multiple projects across Brazil, including Serabi’s redevelopment of the Palito process plant and the installation of Serabi’s ore sorter circuit. The detailed engineering design of the Coringa process plant is advancing well and is expected to be concluded by Q2.

| “dacite porphyry intrusive” | a silica-rich igneous rock with larger phenocrysts (crystals) within a fine-grained matrix |
| “deposit” | is a mineralised body which has been physically delineated by sufficient drilling, trenching, and/or underground work, and found to contain a sufficient average grade of metal or metals to warrant further exploration and/or development expenditures; such a deposit does not qualify as a commercially mineable ore body or as containing ore reserves, until final legal, technical, and economic factors have been resolved. |

Assay ResultsAssay results reported within this release include those provided by the Company's own on-site laboratory facilities at Palito and these will not have been independently verified. Serabi closely monitors the performance of its own facility against results from independent laboratory analysis for quality control purpose. As a matter of normal practice, the Company sends duplicate samples derived from a variety of the Company's activities to accredited laboratory facilities for independent verification. Since mid-2019, over 10,000 exploration drill core samples have been assayed at both the Palito laboratory and certified external laboratory, in most cases the ALS laboratory in Belo Horizonte, Brazil. When comparing significant assays with grades exceeding 1 g/t gold, comparison between Palito versus external results record an average over-estimation by the Palito laboratory of 6.7% over this period. Based on the results of this work, the Company's management are satisfied that the Company's own facility shows sufficiently good correlation with independent laboratory facilities for exploration drill samples. The Company would expect that in the preparation of any future independent Reserve/Resource statement undertaken in compliance with a recognised standard, the independent authors of such a statement would not use Palito assay
