(“Serabi” or the “Company”)
Successful high-grade exploration drilling extends the newly developed Mogno and Ipe lodes at depth and potentially along strike.
Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to update the market on exploration drilling results from the Palito Mine where the combination of surface and underground exploration drilling has confirmed depth and plunge continuity of the high grades in the Mogno and Ipe lodes.

Highlights
Drilling on the Mogno and Ipe veins at the Palito Mine has confirmed depth extensions by over 100 metres below the lowest mined level. Furthermore, step out drilling indicates additional payable ore shoots up to 600 metres along strike in both directions.
Significant down plunge intersections on the Mogno lode from underground exploration drilling include:
- PUD0578 – 0.75m @ 39.96 g/t Au
- PUD0635 – 0.50m @ 12.52 g/t Au
- PUD0679 – 1.00m @ 51.76 g/t Au
- PUD0681 – 0.85m @ 35.31 g/t Au
- PUD0684 – 1.25m @ 17.29 g/t Au
Down plunge intersections on the Ipe lode from underground drilling include:
- PUD0684 – 2.05m @ 13.54 g/t Au
- PDD0566 – 0.89m @ 36.62 g/t Au
Surface drilling has highlighted a number of potential new ore shoots along strike on both lodes. On the Ipe vein, PDD0565 intersected 0.95m @ 3.49g/t Au 600 metres to the NW of the mine current development, and PDD0573 intersected 1.25m @ 3.64g/t Au 400 metres to the SE of the current mine development, opening up the possibility of a very significant resource increase.
On the Mogno Vein previous drilling undertaken in 2018 also indicated this vein to be gold bearing 600 metres to the SE of the current mining area with PDD0533 having intersected 0.5m @ 1.38g/t Au whilst PDD0534 intersected 0.5m @ 2.06g/t Au.
Mike Hodgson, CEO of Serabi, commented:
“The Ipe and Mogno lodes are increasing their contribution of the Palito Mine ore feed due to their relative shallow depth and high grades. Both these veins are being mined less than 200 metres from surface so are easily accessed and with the main ramp already deepened to over 350 metres from surface, both Ipe and Mogno do not require much capital development.
“Both shoots are extremely rich in both gold and copper with grades similar to the G3 vein which was a major contributing vein to Palito production in previous years. The confirmation that these veins are continuing at depth is excellent news and bodes well for the future of the operation. Furthermore, the drill results indicate significant potential to extend resources laterally along strike. We will continue drill testing these strike extensions over the coming months, and if we see a replication of the ore shoots currently being mined, this will confirm the potential for these two vein structures to continue make a major long-term contribution to gold production.
“With drilling still ongoing at the Sao Chico and Sao Domingos prospects and a fourth rig arriving in June, we look forward to providing further exploration results to the market over the coming months.”

| Reported intercepts calculated based on a minimum weighted average grade of 0.5g/t Au using a 0.5g/t Au weighted average lower cut and a maximum internal waste interval of 1.2m based on ALS and Serabi´s on-site lab reported analyses. Assay results reported within this release for surface drilling have been provide by ALS laboratories in Brazil whilst assay results for underground drilling are those provided by the Company's own on-site laboratory facilities at Palito and have not yet 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 results without sufficient duplicates from an appropriately certificated laboratory.
