Airborne survey from Sao Domingos delineates continuation of significant magnetic feature and enhance structural understanding
Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, i is pleased to provide results from its geophysical airborne survey over its Sao Domingos Property, in the Tapajos region of Para State, Northern Brazil.

Highlights
Mike Hodgson CEO commented:
“The much anticipated results of the survey have not disappointed. We acquired the Sao Domingos tenement in late 2019. With prolific past and present artisanal gold production, multiple gold occurrences but little systematic exploration, the potential to make discoveries was clear. With a significant number of potential targets for consideration prior to the survey, the results of this survey now provide real focus. The spatial relationship between the high magnetic feature and known Sao Domingos prospects is consistent with our findings along the Mata Cobra belt which hosts several prospects we are already investigating, such as Calico, Juca, Ganso and Forquilha and provides an excellent additional screen to generate further targets. Two of these prospects are the Toucano trend which we have drilled with great success, and the very exciting Matilda geochemical anomaly that lies between Sao Domingos and Sao Chico. This new survey highlights potential beyond these targets and demonstrates the extension of the Mata Cobra magnetic anomaly to over 40km.”

RESULTS
This iinterpretation of the new airborne survey indicates the westward extension of the Mata Cobra trend and fertile structures a further 15km into the Sao Domingos area. Regionally the corridor hosts several high priority targets including Calico, Juca, Ganso and Forquilha. This has generated new targets to be followed up with geochemical sampling and reconnaissance mapping of the Sao Domingos area in 2022.
The principal targets within the newly surveyed Sao Domingos area, Toucano and Matilda, both present specific magnetic signatures.
The Toucano Trend, which was drilled in 2021 with intersections including 7.15m at 258.24 g/t gold, lies parallel to and on the periphery of the magnetic high in an area of low magnetism, interpreted as caused by magnetite destruction by alteration. This proximal relationship is mirrored by the Pedro and Fofoca prospects to the north and is similar to other prospects on the main Mata Cobra trend.

Results also show a subtle but distinct magnetic feature at the Matilda target, interpreted to represent hydrothermal magnetite occurring within potassic alteration. Inversion modelling of the magnetic data was completed and shows a deep annular (or doughnut) shaped magnetic feature, with several protrusions extending to within 200m of the surface interpreted to represent magnetite-rich potassic zonation, typical of porphyry systems. The magnetic feature occurs directly beneath the surface geochemistry anomalies of gold, copper and molybdenum.

The magnetic interpretation of the Toucano and Matilda prospects will assist in drill targeting and focussing the broader exploration efforts during 2022 as Serabi in the highly prospective Sao Domingos tenement area.

| “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 Results
Assay 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
