Demonstrates Further Growth Potential

Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to update the market on ongoing drilling from the Sao Chico project where brownfields diamond drilling has further demonstrated the potential of extensions to the main mineralised corridor on the Julia lode and the existence of a series of parallel mineralised structures that should be accessible using existing mine infrastructure.

Highlights

• Surface drilling on the Julia Vein (Zone 3) intersected significant shallow mineralisation including
  
  4.30m @ 8.52g/t Au
  
  (including 0.80m @ 31.08g/t),
  
  2.55m @ 14.29g/t Au
  
  (including 0.50m @ 66.70g/t Au) and
  
  0.8m @ 11.85g/t Au
  
  to 100 metres below surface.
• Drilling on the Julia Vein (Zone 4) intersected 0.6m @ 3.46g/t Au indicating shallow mineralisation continues from Zone 3 into Zone 4, a western extension of the shallow mineralisation across a dacite dyke intrusion.
• Julia Vein underground drilling intersected
  
  3.3m @ 12.02g/t
  
  indicating a potential deeper mineralised shoot developing below 200 metres vertical depth on Julia Zone 3.
• Remodelling and interpretation of historic data has identified a parallel structure approximately 70 metres to the south of the Main Vein, containing several small, but very high-grade shoots. Named “Gabi”, recent underground drilling to confirm this vein target returned results including 0
  
  .55m @ 18.24g/t Au
  
  .
• Drill testing of an induced polarisation geophysical anomaly 100 metres north of the Main Vein and adjacent to the decline ramp intersected 1.95m @ 3.63g/t Au including
  
  0.70m @ 8.88g/t Au
  
  on the Lagoa Intermediate target.

Mike Hodgson, CEO of Serabi, commented:

“These recent drill results on the Julia Vein to the west of the mine, and the previously overlooked historical drilling into the Gabi Vein, to the south of the mine are very encouraging.   These are satellites that are close to surface, therefore are easy to develop and require minimal capital development to access them.

“Our initial understanding of the Julia Vein was that the mineralisation had been truncated to the west by dacitic intrusions, and the vein was limited to what we called zones 1 and 2. We have now drilled to the west of this area and found the continuation of the intrusive structures, with good vein widths and grades.

“All these intersections lie in the zone 3 block, immediately west of the current mine limit. Zone 3 is itself bounded to the west by another dacite dyke, but we have now intersected the further continuation of Julia west of this dyke and with further drilling hope to see a repetition of zone 3 in zone 4. As can be seen from the long section (Figure2), we are now focussing on drilling the upper levels of zone 4 from surface, and hope for further positive results.

“Recent drilling has also led us to review some historic Sao Chico drilling results and core with encouraging results, notably the identification of the Gabi Vein. Located 70 metres south of the Main Vein it was intersected with early Sao Chico drillholes that were targeting the Main Vein. As is often the case, the Gabi structure, being narrower and not the primary target, was overlooked at the time. Re-interpretation and a good deal of re-logging and sampling is building a very interesting and encouraging prospect that justifies further development of the Gabi Vein.”

RESULTS

Julia Vein

The Julia Vein, discovered in the 2016 extension drilling campaign, is a mineralised vein structure located close and parallel to the Main Vein. The Julia Vein develops west of a NE-SW cross cutting structure, which effectively terminates economically mineable grades within the Main Vein. The Julia Vein is interpreted to be the focus of gold mineralising fluids west of the cross-cutting structure and although the Main Vein structure extends in its parallel position, the gold grades within the continuation of the mineralised structure are not significant.

Julia is cut by a series of cross-cutting, NE-SW trending dacite dykes and therefore broken into a series of dyke-bound blocks referred to as Zones 1, 2, 3 and 4. Mine development and stoping has occurred on the shallow portions of Zone 1 and 2, and the deeper portion of Zone 1. Recent surface drilling into the shallow portion of Zone 3 and 4 has returned some significant drilled intercepts at mineable widths. Drilling on the Julia Vein (Zone 3) intersected significant shallow mineralisation including 21-SC-210 with

4.30m @ 8.52g/t Au

from 66.70m (including 0.80m @ 31.08g/t), 21-SC-211 with

2.55m @ 14.29g/t

Au from 84.45m (including 0.50m @ 66.70g/t Au) and 21-SC-212 with

0.8m @ 11.85g/t Au

from 68.35m (including 0.35m @ 22.46g/t Au).

These recent drilling intercepts demonstrate that Zone 3 contains mineable grades down to 100m vertical depth and along a 100 metre strike of the Julia Vein.

Surface drilling in 2020 into Zone 3, did not return any significant intercepts between 100 metres and 200 metres vertical depth. However, recent underground drilling has demonstrated that mineable mineralisation exists below 200 metres vertical depth with drill holes 21-SCUD-523 reporting

3.3m @ 12.02g/t Au

, 21-SCUD-517 with 0.92m @ 1.07g/t Au, 21-SCUD-542 with 0.61m @ 1.45g/t Au and 21-SCUD-546 reporting 0.83m @ 1.73g/t Au.

Recent surface drilling into Julia Zone 4 returned an intercept of 0.6m @ 3.46g/t Au from 136.55m in drill hole 21-SC-192. This intercept indicates shallow mineralisation continues from Zone 3 into Zone 4. As such a follow-up programme of a further six shallow surface drill holes is planned to confirm this western strike extension of the Julia Vein.

Gabi Vein

The Gabi Vein lies 70 metres south of the Main Vein and current mine infrastructure. This vein was intersected in the initial 2011 drilling campaign where deeper drilling targeting the Main Vein cut the Gabi Vein in the shallow portion of the drill holes. Intersected by six shallow diamond drill holes, a single significant intercept of

1.31m @ 10.0


0


g/t Au

from 11-SC-021 was reported.

Similarly in the subsequent 2013 drilling campaign the vein was intersected by eight drill holes whilst targeting the deeper portion of the Main Vein, with the significant intercept of

0.70m @ 103.64g/t Au

in 13-SC-049. The Gabi structure was again pierced in the subsequent 2015 campaign, however, on this occasion, without reporting significant mineralisation.

In 2018, underground drilling intersected the vein whilst targeting the Cross Roads induced polarisation geophysical anomaly. Two holes were completed returning 1.39m @ 3.96g/t Au (18-SCUD-207) and 0.36m @ 3.71g/t Au (18-SCUD-206) from the Gabi structure. The structure was also pierced by surface drilling undertaking strike extension exploration of the Main Vein.

In 2019 and 2020 surface drilling campaigns conducted on the Highway Zone of the Main Vein intersected the structure shallowly to the east. A significant intercept of

0.38m @ 25.36g/t Au

was returned from drill hole 19-SC-139.

In 2021, following an exercise of data re-modelling and structural interpretation, the Gabi structure was recognised as being a significantly strike extensive structure (more than 700 metres) containing two possible mineralised shoots. Underground drilling, targeting the eastern shoot, has recently been completed. Seven holes were undertaken with significant intercepts including

0.55m @ 18.24g/t Au

(21-SCUD-544) and 0.61m @ 1.45g/t Au (21-SCUD-542). Two holes still have assay results pending.

The eastern mineralised shoot on the Gabi Vein appears to represent a narrow sub vertical zone of mineralisation extending over 200 metres vertically and approximately 100 metres along strike.

The western mineralised shoot is indicated by drill holes 11-SC-021 and 13-SC-049 but is yet to be targeted.

Lagoa Intermediate

Lagoa Intermediate is a chargeable induced polarization anomaly defined in 2018 and located approximately 100 metres north of the Main Vein and adjacent to the decline ramp.

Initially tested in 2018 by a single drill hole 18-SC-115, three zones of veining and alteration were intersected returning grades up to 1.28g/t Au.

Recently drill hole 21-SC-214 scissoring the previous hole intersected

1.95m @ 3.63g/t Au

from 123.05m including

0.70m @ 8.88g/t Au

from 124.30m and 0.5m @ 1.15g/t Au from 126.65m.

This drilling further validates the mineral potential in the Lagao Intermediate anomaly in juxtaposition to the mine infrastructure. Further drilling will be undertaken to improve the definition of this anomaly in the coming months.

Significant intercepts reported from the Sao Chico brownfields exploration are summarised in the table below.

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 Serabi´s on-site lab reported analyses. The assay results reported above are those provided by the Company’s own on-site laboratory facilities at Palito and have not 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.
