Serabi exceeds production guidance for 2022

Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to report operational results for the final quarter of 2022 and provide a review of its development and exploration activities.

HIGHLIGHTS

•     Fourth quarter gold production totalled 7,798 ounces, taking annual production to 31,819 ounces, exceeding the annual production guidance of 30,000 ounces.
•     The Coringa mine development continued to progress well, with 1,791 metres of development completed during the year, approximately 1,000 metres of which was in ore. The main ramp has now reached the 290mRL, which is under development.

Mike Hodgson, CEO of Serabi, commented:

“The company has ended the year with a very satisfactory 7,800 ounces produced for this final quarter, which sees the total gold produced for the year just short of 32,000 ounces, comfortably ahead of the revised 2022 guidance of 30,000 ounces. The fourth quarter has been somewhat transitional as we have been moving some mining crews and fleet from the Sao Chico orebody over to Coringa. To date, the Coringa deposit has been in a development phase and as we begin 2023 will we see the first production from stoping, and this will result in an increase in the level of Coringa ore being delivered to the Palito plant. It was therefore particularly pleasing to maintain steady mine output from Palito Operations, even with reduced levels of manpower and equipment.

“It is an exciting time for the Company, and we look forward to 2023 being a year of improving production. Having ‘flat-lined’ for the past 2 years, 2023 should see Coringa really begin to contribute as well as improved output from Palito operations. The rate of the Coringa production growth remains subject to the on-going licencing process. Over the year, we have drilled over 17,000 metres of underground exploration drilling in and around the Palito mine, stepping out and down on known veins. As a result, it is our intention to publish an updated Independent NI 43-101 Mineral Reserve and Mineral Resource Estimate during the first half of the year. In addition, we will be keeping stakeholders updated on progress with the planned greenfield exploration programmes following the discovery of the Matilda copper-molybdenum porphyry during 2022.”

OPERATIONAL RESULTS

Total production for the fourth quarter of 2022 was 7,798 ounces, bringing total production for the year to 31,819 ounces, which includes a fourth quarter and annual contribution from Coringa of 443 and 1,013 ounces respectively.

Total ore mined from the Palito Complex during the fourth quarter was 38,293 tonnes at 6.20 grammes per tonne (“g/t”) compared to 43,180 tonnes at 6.28 g/t of gold for the third quarter of 2022. Total ore mined for the year was 163,506 tonnes at 6.15 g/t, compared with 170,261 tonnes at 6.59 g/t for 2021. Development ore produced from Coringa generated a total of 7,654 tonnes at 4.78 g/t in the year.

42,692 tonnes of run of mine (“ROM”) ore were processed through the plant during the final quarter, with an average grade of 6.05 g/t of gold, compared with 44,867 tonnes at 6.34 g/t in the third quarter. 172,404 tonnes of ROM at 6.14 g/t were processed for the year, which included 5,729 tonnes of Coringa ore with a grade of 5.68 g/t.

A total of 2,245 metres of horizontal development has been completed at Palito during the final quarter of which 1,233 metres was ore development. The balance is the ramp, cross cuts and stope preparation development. Horizontal development at Coringa totalled 645 metres during the fourth quarter.

   Mine performance in the final quarter of 2022 was impacted by reduced output from the Sao Chico orebody reflecting the decision taken mid-year to move some crews and fleet to Coringa in readiness for increased Coringa production in 2023. Whilst planned output from the Palito orebody was increased to offset the Sao Chico output, total mined tonnage from Palito Operations nonetheless reduced by 4,900 tonnes for the quarter.
   The extensive underground exploration drilling programme of 2022 has seen over 17,000 metres of drilling completed. Large step outs have been tested on the veins of Chico de Santa, G3 Central, G3 North and Senna at depth. The plan has been to drill at least 250 metre depth extensions below all sectors, as well as strike extensions where access has been possible. As a result, a significant effort has been made during the second part of 2022 to compile these results and update the drill hole database and the geological models for the ore zones at Palito and Sao Chico. The company is working with consultant NCL who will prepare a new NI 43-101 Technical Report comprising updated Mineral Resource and Mineral Reserve estimates during the first half of 2023. FINANCE UPDATE Cash balances at the end of December 2022 were US$7.2 million with a further cash receipt of US$2.2 million being received in early January for a sale of copper/gold concentrate completed in December. This compares with a cash balance of US$10.3 million at the end of September 2022. 2023 PRODUCTION GUIDANCE The Company forecasts combined production from the Palito Complex operations and Coringa Project of between 33,500 and 35,000 ounces of gold during 2023.

"Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed. "Inferred Mineral Resource” is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. “Inferred Mineral Resource” ‟ is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity.

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 Qualified Persons Statement
