OPERATIONAL RESULTS

Palito Operations

• First quarter gold production of 7,062 ounces, a 13% reduction compared to the same period of 2021 (Q1 2021: 8,087 ounces).
  • Total ore mined during the quarter of 40,606 tonnes at 5.95 grammes per tonne (“g/t”) of gold, compared with 40,371 tonnes at 6.27g/t for the same period in 2021.
• Production was impacted by continued supply chain issues and greater than expected dilution from the Julia Vein of the São Chico orebody. Shrinkage stoping has been adopted to address this but will result in delayed production and guidance for 2022 is therefore reduced to 30,000 ounces from 36,000 to 39,000 ounces previously.
• 41,357 tonnes of run of mine (“ROM”) ore were processed through the plant from the combined Palito and São Chico orebodies, with an average grade of 5.72 g/t of gold, compared with 41,462 tonnes at 6.27 g/t for the same period in 2021.
• 2,938 metres of horizontal development completed during the quarter

DEVELOPMENT HIGHLIGHTS

Coringa Project

• Underground development of the ramp has now intersected all three veins (V1, V2 and V3) on at least one level. The V3 and V1 veins of the Serra Zone were intersected on the 320m and 340m levels (see news releases dated 28 January and 11 March 2022) with channel samples recording better than expected results including:
  • SRR-320-019 - 1.25 metres @ 7.84 g/t Au
  • SRR-320-012 - 0.86 metres @ 12.44 g/t Au
  • SRR-340-004 - 0.40 metres @ 14.61 g/t Au

• Additional results since 11 March 2022 from the V3 development delivered high grade results including:
  • SRR-340-006 - 0.40 metres@ 30.28 g/t Au
  • SRR-340-010 - 0.52 metres @ 21.25 g/t Au
  • SRR-340-015 – 0.34 metres @ 70.06g/t Au

EXPLORATION HIGHLIGHTS

• Palito: Drilling within the Chica da Santa (CDS) sector, currently the eastern limit of the Palito mining operation, continued to generate positive results from the Ipe and Mogno veins and additional drilling from both underground and on surface further to the north east has delineated a further sector containing the Pele, Romario and Bebeto veins (see news release dated 5 January 2022).
  • High grade underground intercepts include:
    • 0.50m @ 22.56g/t Au (Ipe) from 39.30 metres to 39.80 metres (PUD0709)
    • 1.05m @ 68.09g/t Au (Ipe) from 41.25 metres to 42.30 metres (PUD0726)
    • 1.50m @ 76.09g/t Au (Ipe) from 61.70 metres to 63.20 metres (PUD0727)
  • High grade surface intercepts include:
    • 1.40m @ 14.39g/t Au (Pele) from 106.40 metres to 107.80 metres (PDD0607)
    • 0.82m @ 24.70g/t Au (Jatoba) from 57.38 metres to 58.20 metres (PDD0415)
    • 2.00m @ 33.76g/t Au (Jatoba) from 76.75 metres to 78.75 metres (PDD0558)
• Palito: Shallow drilling at the Piaui prospect confirmed the continuity of three major parallel mineralised structures and identifies further smaller parallel zones, 500 metres from the current underground mine infrastructure.
  • Visible gold encountered in PDD0619 within a zone grading 2.6m @ 13.37g/t Au including 0.75m @ 33.74g/t Au from 28.55m.
  • High grade intercepts include:
    • 0.41m @ 16.89g/t Au from 26.40m, 1.94m @ 11.86g/t Au including 0.70m @ 19.15g/t Au from 35.30m (PDD0618)
    • 0.65m @ 14.28g/t Au from 43.1m, 5.90m @ 4.11g/t Au including 1.00m @ 17.56g/t Au from 69.75m (PDD0617)
• São Domingos Regional: Results from 1,929 line kilometres of airborne magnetic survey over the highly prospective São Domingos property, to the west of the São Chico operation, extends the Mata Cobra magnetic trend into the São Domingos property and extends the strike length of the corridor from 25km to over 40km. Mata Cobra is a magnetic trend that dominates the central part of the tenement and which has a coincident copper and gold soil geochemical anomaly.
• Matilda: The Matilda prospect shows a subtle but distinct magnetic signature coincident with the extensive soil geochemical anomaly, interpreted to reflect a magnetite alteration halo.

Mike Hodgson, CEO of Serabi, commented:

“The first quarter results for 2022 have been somewhat mixed. We have had some excellent, and better than anticipated results from the underground development at Coringa, most specifically on the first of the five ore zones, the Serra Zone. We have progressed development of V3 to the north and south of the ramp on both levels and these early results have been extremely promising. As we advance to the north, we also expect to see improved widths.

“At Palito, the first quarter production results have been disappointing with 7,062 ounces produced, and while March was a significantly better month with improved grades and production, it was not possible to recover earlier shortfalls in planned production due to delays in receiving new mining fleet which while ordered in mid-2021 are only now built and becoming available for delivery. As a consequence, by having to rely on older machinery we have, in the short term, mined and processed the ore in immediately accessible blocks, including those with lower grades, which contributed to lower than anticipated gold production over the last six months. However, all new items of fleet have been delivered or are expected to be delivered during the second quarter of 2022 and we are confident that we can increase production from the already identified new vein structures during the remainder of 2022 and in 2023.”

“At São Chico, dilution in the Julia Vein from mechanised long hole open stoping was also higher than expected as a consequence of the presence of parallel and cross cutting faults and intrusive dykes which post-date the ore. This level of faulting appears to be unique to the Julia Vein. We have therefore decided to change the mining method on the Julia Vein and introduce selective open stoping, the method used successfully on the Palito orebody, and which will over time be expected to improve grades by minimising dilution through greater selectivity in the mining. 1,000 ounces of production which had been scheduled from São Chico in February by long hole, will now be mined selectively during the second quarter and over the rest of the year.

“The decision to mine selectively on the Julia Vein means the reliance on production ounces will, in the near term, focus on the Palito orebody, with operations at São Chico focusing more on mine development with a view to a return to planned production levels later in the year and into 2023. In the short term we will be focusing on producing profitable ounces and maximising operational cashflow rather than production growth for the rest of the year, and we are therefore revising our production guidance to be in the region of 30,000 ounces for 2022.

“The real scale change on production ounces will be driven by the successful start-up of Coringa where we have enjoyed a very encouraging initial mine development. During the quarter, we intersected the three veins of the Serra Zone on the 340m and 320m levels. The results to date have been excellent, and as we develop the two principal veins, V1 and V3 to the north we are recording far better grades than forecast. As a result, we have introduced ‘resue’ development mining, where the ore and waste can be blasted separately. The advantage of this is that dilution of the ore coming out of the mine is minimised. The intention is to build a high-grade stockpile over the coming months.

“On the permitting side, matters continue to progress well. We have had positive meetings with SEMAS, the State Environmental Agency. We continue to expect this will result in Serabi receiving the LI in the coming few months.

“Exploration results from the Palito Mine have been very encouraging. The Ipe and Mogno veins in the Chica da Santa sector, have demonstrated the depth potential and continued high grades of the sector. The Piaui sector hosts two veins, which have now been drilled over a strike length of 500m and 200m vertical depth. Plans are now being finalised to crosscut to this sector from the Senna vein later this year.

“The potential of Palito both along strike, at depth and now laterally is clear to see. From Pele in the east and Piaui in the west, the deposit now comprises a series of veins within a 1,000m wide corridor . Over the next 12 months, we will be expanding the Palito orebody considerably as we access these new sectors.

“Whilst the last two years have been tough operationally due to global supply chain issues and impacts of Covid, we are confident in Serabi’s future. The Palito orebody remains the engine room to our production base but with a turnaround expected at São Chico this year and the material growth from Coringa, our strategy remains to turn Serabi into a multi-asset gold miner with production approaching 100koz within the next few years.”

FINANCE UPDATE

Cash balances at the end of March 20212 were US$6.9 million with a further receipt of US$1.6 million for a sale of copper/gold concentrate due to be received in early April. This receipt was delayed from March following late changes in sailing schedules. The reduction in cash holdings since 31 December 2021, reflects the continued development expenditure of Coringa during the quarter, and the reduced level of sales revenue generated in the period as a result of lower production.

The Company anticipates that the audited financial results for the Company for the year ended 31 December 2021 will be released in the middle of May.

2022 PRODUCTION GUIDANCE

In light of the issues identified during the first quarter of 2022 and the measures that the Company is putting in place, production guidance for 2022 has been reduced to approximately 30,000 ounces from 36,000-39,000 as previously for the full year.

GLOSSARY OF TERMS

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
