Significant increase in gold resource for Palito- Updated Mineral Resource Statement

Serabi Gold (AIM:SRB, TSX:SBI), the Brazilian focused gold mining and development company, is pleased to announce updated Mineral Resource estimates for its Palito Complex (being the Palito deposit and the Sao Chico satellite deposit), prepared in accordance with the standard of CIM and Canadian National Instrument 43-101 with an effective date of 30 June, 2023 as outlined below.

HIGHLIGHTS

Measured and Indicated (“M&I”) resource of 377,800 ounces of contained gold, an increase of 50% compared with December 2021, at the Palito Complex (1,166,300 tonnes at an average in-situ grade of 10.08 g/t).

Further Inferred resource of 153,900 ounces (682,400 tonnes at an average in-situ grade of 7.01 g/t).

Significant increase in average reported grade of the M&I resources at Palito Complex by 93% from 5.23 g/t to 10.08g/t.

Increase in average reported grade of the Inferred resource by 45% from 4.83 g/t to 7.01g/t.

NCL Consultoria en Ingenieria en Minas of Santiago, Chile (”NCL”) who have prepared this Mineral Resource estimation are preparing an updated Mineral Reserve estimate and the accompanying NI 43-101 Technical Report which is expected to be issued within 45 days of the date of this release.

(Note: All resource figures stated above are both gross and net attributable to Serabi.)

Mike Hodgson, CEO of Serabi, commented:

“This significant increase in geological resources for the Palito deposit since the last published estimation as of December 2021, is the result of an aggressive underground drilling programme over the last 18 months which has clearly been very successful. I am pleased to report that we now have a total mineral resource inventory across Coringa and the Palito Complex in excess of one million ounces.

“We have continually maintained that Palito is a long-life asset which can be difficult to demonstrate within a narrow vein underground deposit. When mining started in 2005, the maiden resource was approximately 400,000 ounces. With over 15 years of production during which more than 400,000 ounces has been mined, and to now have a new total mineral inventory in excess of 500,000 ounces is not only extremely encouraging but it clearly demonstrates the geological potential and a successful resource replacement strategy. We have no reason to believe this will not continue. It is also particularly pleasing to see a significant jump in grade.”

“The veins comprising the Palito resource lie within an approximate one kilometre strike with a further three kilometres remaining to be tested indicating the potential for more future upside.

“We wait to see how this translates into Mineral Reserves when mining dilution is taken into account, but I anticipate an uplift on the previous Mineral Reserve estimate of 58,000 ounces.”

The mineral resource estimate was prepared by Mr Nicolas Fuster of NCL Consultoria en Ingenieria en Minas, who is a Qualified Persons under the Canadian National Instrument 43-101.

Mineral Resource Estimates

The updated Mineral Resource estimates for the Palito Mine (Table 1) and the Sao Chico Mine (Table 2) are based on data as at June 30 2023.

Total Mineral Resources Statement for the Palito Complex (Palito and Sao Chico Mines), Para, Brazil (effective 30 June 2023)

Notes to Table 1:

• Mineral Resources are not Mineral Reserves and have not demonstrated economic viability. Mineral Resources are reported inclusive of Mineral Reserves. All figures are rounded to reflect the relative accuracy of the estimates. Mineral Resources are reported within classification domains inclusive of in-situ dilution at a cut-off grade of 3.32/t gold assuming an underground extraction scenario, a gold price of US$1,950/troy oz, an operating cost of $198/t, and metallurgical recovery of 95%.
• Serabi is the operator and owns 100% of the Palito Complex such that gross and net attributable mineral resources are the same. The mineral resource estimate was prepared by NCL Consultoria en Ingenieria en Minas in accordance with the standard of CIM and Canadian National Instrument 43-101, with an effective date of 30 June 2023 by Mr Nicolas Fuster, who is a Qualified Person under the Canadian National Instrument 43-101.
• Polygonal techniques were used for Resources estimates.

Assay Results

Assay results reported within this release include 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.
