Exploration Update

Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to announce first exploration drilling results at the recently acquired Sao Domingos project (see news release issued 19 October 2020) and continued success with ore body extension drilling at the Sao Chico deposit.

Sao Domingos

  • Following encouraging regional reconnaissance work within the Sao Domingos property, the Company elected to focus on the 600 metre long, high-grade gold prospect, Toucano, located eight kilometres west of the Company’s Sao Chico operation.  The first three diamond drill holes have been completed and the following strong set of intersections recorded:  
  • 5.00m @ 24.09g/t Au including 1.5m @ 67.69g/t (Hole 20-SD-003)
  • 0.55m @ 11.3g/t Au (Hole 20-SD-001)
  • 1.4m @ 5.01g/t Au (Hole 20-SD-002)
  • The exploration drillholes have been supplemented by the first partial surface channel samples including:
    • 2.9m @ 5.99g/t Au (CHRLR-001)
    • 5.0m @ 7.11g/t Au (CHTOU-002)
    • 1.0m @ 5.84g/t Au (CHSCO-003)
    • 4.0m @ 1.05g/t Au (CHSCO-005)
    • 8.0m @ 3.02g/t Au (CHSCO-012)


  • Thirteen in-situ surface rock chip samples were also taken over the Toucano zone and returned promising results including gold values of 2.36g/t to 513.01g/t gold, averaging 95g/t gold.

Sao Chico

  • Surface and underground exploration diamond drill holes have targeted a new ore zone, the Julia Vein, which lies to the north of the main orebody currently being mined.  Significant intersections include:
    • 0.55m @ 12.79g/t Au (Hole 20-SC-177)
    • 1.50m @ 7.23g/t Au (Hole 20-SC-179)
    • 0.40m @ 7.45g/t Au (Hole 20-SC-183)
    • 0.65m @ 12.31g/t Au (Hole 20-SC-187)
    • 1.85m @ 8.62g/t Au (Hole 20-SCUD-370)
    • 5.90m @ 60.09g/t Au (Hole 20-SCUD-377)
    • 1.92m @ 38.89g/t Au (Hole 20-SCUD-381)
    • 4.20m @ 27.12g/t Au (Hole 20-SCUD-386)

Mike Hodgson, CEO of Serabi, commented:

“The pandemic interrupted our exploration activities in 2020, but by November we had drill rigs back on site, at Sao Chico and Sao Domingos.  Sao Domingos has been a property that we have wanted to acquire for considerable time, so we wasted little time getting exploration up and running there.  The Toucano prospect at Sao Domingos is a walk up and drill target.  We only secured access in late November and have worked as quickly as possible to complete some initial drilling.  To obtain such encouraging results so quickly into the programme is really pleasing and supports our initial hopes for this area.  The Toucano prospect has had three artisanal open pits, each of which have been mining a south west to north east trending mineralised zone, which at surface is 20 metres wide.  The mineralised zone has been traced over 600 metres, and we are investigating this mineralisation at depth.  All three holes intersected payable grades, and the stand-out intersection of 24.09 g/t gold over five metres width at a vertical depth of 70 metres is very encouraging. 

“In parallel to the drilling we are undertaking multiple trenching and rock chip programmes to test the surface grades, and although this sampling is far from complete, the initial showings are also very exciting. 

“Drilling at Toucano has restarted following the Christmas break and we will continue to test with drilling the near surface potential along the entire 600 metres zone, as well as infill the channel and rock chip sampling programmes on surface, to build up a good three-dimensional understanding of the prospect. 

“In addition to Toucano, Sao Domingos hosts many prospects where the artisanal miners have successfully mined oxide ore and we have started an initial reconnaissance programme of rock chip sampling over the property.  The results have been equally encouraging and we will be following up on the best of these in the coming months. 

“At Sao Chico, we have also enjoyed a successful restart to the exploration programme, focused on the western extension of the Sao Chico orebody and in particular a new zone discovered to the north of the main orebody being mined, called Julia.   The Julia Zone was identified when the mine initially opened in 2015, but only in the central part of the mine, and at that time, did not yield particularly encouraging results.  As a consequence, the mine development continued to focus on the Main Zone.  It is only now while we have been investigating the main orebody to the west and beyond the current mine limits, that we have intersected the Julia Zone, but this time demonstrating mineable widths and grades.  To date approximately 30 holes have been drilled from both surface and underground, with some results still pending, and the drill programme is on-going.   Results so far have been very positive.  Eight of the holes drilled have recorded significant grades ranging from 7.23 g/t gold up to over 60 g/t gold over mineable widths. This recent success highlights the possibility that the Julia Zone is a parallel zone to the main orebody and potentially extending along the current 600 metre strike length of the Main Zone of the Sao Chico ore body and could well extend to the east as well.  This opens up the potential to develop the mine northwards.  As further results from the Sao Chico programme are generated, we will continue to provide updates.

CIM means the Canadian Institute of Mining, Metallurgy and Petroleum.
chalcopyrite” is a sulphide of copper and iron.
Cu means copper.
cut-off grade the lowest grade of mineralised material that qualifies as ore in a given deposit; rock of the lowest assay included in an ore estimate.
deposit is a mineralised body which has been physically delineated by sufficient drilling, trenching, and/or underground work, and found to contain a sufficient average grade of metal or metals to warrant further exploration and/or development expenditures; such a deposit does not qualify as a commercially mineable ore body or as containing ore reserves, until final legal, technical, and economic factors have been resolved.
electromagnetics is a geophysical technique tool measuring the magnetic field generated by subjecting the sub-surface to electrical currents.
“garimpo” is a local artisanal mining operation
garimpeiro is a local artisanal miner.
geochemical refers to geological information using measurements derived from chemical analysis.
geophysical refers to geological information using measurements derived from the use of magnetic and electrical readings.

Geophysical methods include seismic, magnetic, gravity, induced polarisation and other techniques; geophysical surveys can be undertaken from the ground or from the air.
gossan is an iron-bearing weathered product that overlies a sulphide deposit.

mineralised refers to rock which contains minerals e.g. iron, copper, gold.
mt means million tonnes.

Assay Results
The assay results reported in the table within this release 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. Based on the results of this work, the Company’s management are satisfied that the Company’s own facility shows good correlation with independent laboratory facilities. 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 but only use assay results reported by an appropriately certificated laboratory.

Qualified Persons Statement
The scientific and technical information contained within this announcement has been reviewed and approved by Michael Hodgson, a Director of the Company. Mr Hodgson is an Economic Geologist by training with over 26 years’ experience in the mining industry. He holds a BSc (Hons) Geology, University of London, a MSc Mining Geology, University of Leicester and is a Fellow of the Institute of Materials, Minerals and Mining and a Chartered Engineer of the Engineering Council of UK, recognising him as both a Qualified Person for the purposes of Canadian National Instrument 43-101 and by the AIM Guidance Note on Mining and Oil & Gas Companies dated June 2009.

Forward Looking Statements
Certain statements in this announcement are, or may be deemed to be, forward looking statements. Forward looking statements are identified by their use of terms and phrases such as ‘‘believe’’, ‘‘could’’, “should” ‘‘envisage’’, ‘‘estimate’’, ‘‘intend’’, ‘‘may’’, ‘‘plan’’, ‘‘will’’ or the negative of those, variations or comparable expressions, including references to assumptions.
