Visible gold with intersection of 7.2m at 258g/t gold underpins further exploration success at São Domingos.
Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to announce highly encouraging exploration drilling results from the Toucano trend at its São Domingos project, as well as very encouraging results from its regional geochemical survey also at São Domingos.

Highlights
- Visible gold was identified in hole 21-SD-010 which returned a number of intersections including 7.15 metres at 258.24 grammes per tonne (“g/t”) of gold.
- Drilling on the Toucano trend at São Domingos has intersected three mineralised structures, all hosted within a mineralised alteration zone with a true width of 50 metres.
- Mineralisation is confirmed along at least a 400 metre strike length and remains open at depth and along strike.
- Significant new results received include.
- 21-SD-010 – 7.40m @ 1.95/t Au from 141.00m, including 1.90m @ 5.12g/t Au
- 21-SD-010 – 7.00m @ 9.68g/t Au from 151.55m, including 1.40m @ 26.24g/t Au
- 21-SD-010 – 7.15m @ 258.24g/t Au from 172.85m, including 3.55m @ 519.45g/t Au
- 21-SD-005 – 0.80m @ 89.03g/t Au from 140.00m
- 21-SD-005 – 4.70m @ 1.42g/t Au from 76.00m
- 21-SD-003 – 0.50m @ 6.22g/t Au from 42.00m
- 21-SD-003 – 1.80m @ 3.77/t Au from 67.25m
- A Soil Sample geochemical survey, undertaken in the eastern area of the São Domingos tenement that runs into the western part of the Sao Chico Mining License, has defined multiple areas of anomalous gold in soils. These gold in soil anomalies are coincidental with and supported by other multi-element anomalies.
Mike Hodgson, CEO of Serabi, commented:
“These are an excellent set of further results and follow up on the maiden press release for exploration at São Domingos issued on 22 January 2021. Holes 21-SD-003 and 21-SD-010, together with the previously reported hole 21-SD-001, have all been drilled on the same drill cross section and the collective results are building a very encouraging picture. We have identified multiple high-grade veins, of which at least 3 are significant, in a 50 metre wide, sub-vertical, mineralised alteration zone. Hole 010 is the current highlight, where a drilled width totalling 70 metres of alteration was cut, within which multiple high-grade intersections including 9.68 g/t Au over 7.0 metres, 26.24 g/t Au over 1.40 metres and 258.24 g/t Au over 7.15 metres including 519.45 g/t Au over 3.55 metres were recorded. Visible gold was recorded in this last intersection (see Figure 1).
“With holes 21-SD-005 and 21-SD-002, drilled on the next step out section, 200 metres to the north east along strike, returning further encouraging intersections including gold grades of up to 89 g/t, we are very encouraged with how Toucano is evolving. The plan is to complete the drilling along section 1 (see Figure 2) over the Toucano pit area to establish the full strike width of the mineralised zone, before moving along strike to the north east and south west, and repeating the drilling on a series of parallel sections. With artisanal activity and initial drilling already in place, we have a potential strike of 600 metres, and the plan is to replicate the drill coverage undertaken on the central section over that entire strike length.

DRILLING RESULTS
Drilling in the São Domingos prospect has focussed on the Toucano trend, with assay results received from 10 of the holes completed. The Toucano trend is defined by a broad 50 metre true width hydrothermal alteration zone with anomalous gold mineralisation in which Serabi geologists have interpreted a series of quartz veined fault structures containing higher grade zones.

| 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. The majority of the assay results reported within this release 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. | |||||||||||
SOIL GEOCHEMICAL SAMPLING
Geochemical data from soil sampling in the Fofoca area was integrated with historical data from the São Domingos area, and delineated multiple areas of anomalous gold in soils, supported by multi-element anomalism.
Three significant targets have evolved from this new soil geochemistry data and integration exercise.
- The three-kilometre-long gold in soil “Pedro Trend” is interpreted as a strike extension of the Fofoca mineralisation in the adjacent tenement and is supported by a copper/arsenic/antimony anomalism. Multiple gold in soil anomalies nearby with similar orientations, suggest parallel mineralised structures.
- The one-kilometre-long gold in soil “Messias Trend” is interpreted as a strike extension to the high-grade Messias garimpo in the south east of the São Domingos area and is supported by copper/molybdenum/bismuth/antimony anomalism.
- A 1 kilometre by 1.5-kilometre gold in soil anomaly of more than 30ppb, occurs two kilometres directly west of the Cicada target. This new target contains a strong copper/molybdenum/gold/tungsten core, with distal gold/antimony/tellurium/bismuth, a geochemical signature characteristic of oxidised Intrusion Related Gold Systems. The absence of artisanal mining over the target suggests a disseminated style of mineralisation and this intrusive centre may be interpreted as a potential source for mineralisation at the nearby Abelha, Besouro and Cicada targets.
