Further encouraging results confirm the prospectivity of the São Domingos Project

Serabi Gold plc (AIM:SRB, TSX: SBI), the Brazilian-focused gold mining and development company, is pleased to update the market on exploration sampling and ongoing drilling from the São Domingos project where surface sampling and mapping has highlighted the potential of the Atacadão trend and early exploration drilling has confirmed the density and tenor of gold bearing structures. The Atacadão trend lies two kilometres to the south of the Toucano trend.

Highlights

  • Surface sampling totalling 69 rock chip samples with an average grade of 8.33g/t Au over an area of 1.5km x 1.5km and a maximum result of 204.77g/t Au, reflects the prospectivity of the area.
  • Significantly, 36% of samples returned over 3g/t Au with an average of grade of 22.5g/t Au.
  • Mapping has outlined a broad east-west corridor of parallel gold bearing structures transected by a NE-SW mineralised structure. Historic artisanal hard-rock shafts, located at the intersection of these structural orientations, have returned grades of up to 40.59g/t Au.
  • Drilling commenced in July on the Atacadão trend following up on the detailed mapping and rock chip sampling of this prospective trend. A north-south drill traverse, designed to cover the structural intersection has returned early positive results on multiple narrow vein sets grading up to 6.19g/t Au.
  • Separately, the Company has commissioned a regional airborne geophysics survey on São Domingos Project which is expected to be completed by the end of October 2021.

Mike Hodgson, CEO of Serabi, commented:

“These initial results of the surface sampling from the Atacadão trend are very encouraging. The distribution and grade of the rock chip samples demonstrates the strength and scale of the mineralised system. The objective of the drilling is to provide us with a better understanding on the geological controls on gold deposition and, while this is still at an early stage and on the periphery of the trend, the initial results are very promising. We look forward to updating the market with further results over the coming weeks.

“The Atacadão trend is the second prospect in the São Domingos project area to be drill tested. It lies two kilometres to the south of the Toucano trend where the Company has already identified a 50 metres wide alteration zone over a potential strike length of at least 600 metres containing multiple high-grade intercepts. The Company is proving up additional prospects at São Domingos for future drill-testing.

“Elsewhere, Serabi is drilling at the São Chico mine, five kilometres to the east of Atacadão, and now has two drill rigs testing the southern extensions of the Palito orebody. We look forward to updating the market with further result from each of these campaigns.”

Atacadão

Atacadão is one of multiple prospects in the São Domingos project acquired by Serabi in 2020. Since its acquisition, Serabi has been evaluating the potential of the project to host economic resources that could provide additional production ounces to the nearby Sao Chico mine.

Serabi geologists are assessing a series of target areas identified through geological, geophysical and geochemical methods, including Toucano, Maria Dio, Atacadão, Messias and Pedro trends. Additionally, new multi-element geochemical targets continue to be developed through ongoing regional exploration works.

The Atacadão prospect is currently undergoing part of the regional prospect assessment with first pass drilling to determine its economic potential.

Commissioning of Airborne Geophysical Survey

Serabi has also commissioned a fixed wing airborne magnetic and radiometric survey to cover the recently acquired São Domingos project. The survey will be completed by the end of the 2021 dry season and will complement the existing magnetic survey coverage Serabi has undertaken on the exploration tenement package.

Exploration Results

Atacadão was initially tested in 2006 by the previous permit holders completing eleven drill holes along an 800 metre strike. This drilling intersected several narrow, but high-grade intersections within the trend. Although Serabi has not verified nor validated the results reported, drill intersected grades up to 59.97g/t were reported.

More recently Serabi geologists have undertaken a comprehensive field mapping and sampling exercise over a 1.5km x 1.5km area at the Atacadão prospect. As part of this activity, a total of 69 rock chip samples were collected from artisanal workings, geological exposures and field sites.

These rock chip samples returned a maximum of 204.77g/t Au (RKSR000684) and an average of 8.33g/t Au. Significantly, 36% of samples returned over 3g/t Au with an average of grade of 22.5g/t Au.

The field mapping defined a 300 metre wide east-west corridor of stacked parallel gold bearing structures which has been cut by a strongly mineralised structure trending north east to south west. Historic activity undertaken by artisanal miners has included the development of a series of hard-rock shafts which have returned grades up to 40.59g/t Au at the intersection of these structural orientations.

Serabi has now commenced a “top-to-tail” drill traverse across the Atacadão trend to provide a baseline geological context to the trend initially targeting the structural intersections which are interpreted to control or focus the mineralisation. The drill traverse will comprise approximately 11 drill holes and complete a section of approximately 600 metres across the trend.

Results have been received for the first two holes of this traverse. Drill holes 21-AT001, 21-AT-002 and 21-AT-003 were completed on the northern end of the traverse. The holes were completed from the same drill location at different azimuths to test the two dominant vein orientations. These three holes are located in the hangingwall of the interpreted structural intersection.

Results of the first three holes are shown below, indicating the existence of multiple mineralised vein-sets within the hanging wall of the structural intersection target.

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.

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. These forward-looking statements are not based on historical facts but rather on the Directors’ current expectations and assumptions regarding the Company’s future growth, results of operations, performance, future capital and other expenditures (including the amount, nature and sources of funding thereof), competitive advantages, business prospects and opportunities. Such forward looking statements reflect the Directors’ current beliefs and assumptions and are based on information currently available to the Directors. A number of factors could cause actual results to differ materially from the results discussed in the forward-looking statements including risks associated with vulnerability to general economic and business conditions, competition, environmental and other regulatory changes, actions by governmental authorities, the availability of capital markets, reliance on key personnel, uninsured and underinsured losses and other factors, many of which are beyond the control of the Company. Although any forward-looking statements contained in this announcement are based upon what the Directors believe to be reasonable assumptions, the Company cannot assure investors that actual results will be consistent with such forward looking statements.
