Sao Chico upside enhanced with completion of Induced Polarization Survey
Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to announce the completion of terrestrial induced polarisation (“IP”) geophysical survey covering the strike extent of the Sao Chico structural corridor with a number of significant chargeability anomalies identified.

Highlights
Encouraging results from IP survey, identifying a number of anomalies to the south, east and west of the Sao Chico deposit.The Cinderella Anomaly, a chargeability and conductive high over seven kilometres long, trending north east to south west is coincident with a strong magnetic anomaly as well as sporadic electromagnetic anomalies. This triumvirate of geophysical signatures makes this a compelling target.A two kilometre long, east-northeast to west-southwest trending, robust chargeability anomaly, coincident with a subtle magnetic high, situated only two kilometres west of the Sao Chico.An elongate chargeability anomaly lying on the western edge of the survey area.A cluster of chargeability anomalies located in the northwest of the survey area and lying within the Sao Chico strike corridor.A chargeability/conductivity anomaly on the flanks of the Cinderella Anomaly, also hosted within a magnetic high. Extensive surface geochemistry programme to be undertaken to identify and refine drilling targets for 2019.Mike Hodgson, CEO of Serabi, commented:
“As the images demonstrate, the results from this survey have been excellent, and better than we would have expected at the outset. The survey has shown abundant, high quality chargeability anomalies to the south, east and west of the Sao Chico Deposit.
“As I noted following our news release of 20 November 2018, the multiple anomalies that the airborne survey has generated are very exciting, but I feel that this cluster of IP anomalies all located in our exploration tenements, and all within seven kilometres of the Sao Chico deposit, is very significant. I have always considered that Sao Chico had very good potential and these results open up the possibility for the discovery of a number of new orebodies which, though needing further evaluation, could provide rapid and significant resource growth.
“The Cinderella Shear is a very prominent anomaly that we first reported in our news release of 20 September 2018 when we reported the first results from this IP survey. It has also been highlighted in the results obtained from the airborne survey and we have also now extended its strike in this second part of the IP survey. A coincidental linear anomaly which now extends for seven kilometres and where there has been historical artisanal mining activity around the areas that drain from the anomaly, make it an extremely significant anomaly.
“In addition, we have the excellent A, B and C anomalies along strike and to the west of the Sao Chico orebody, which have excellent chargeability properties indicative of sulphide mineralisation. We hope that, following further evaluation, these will evolve to be gold hosting bodies much like the adjacent Sao Chico orebody.
“This survey has provided us with some real potential. The next steps will be an extensive surface geochemistry programme, which we anticipate will further refine the anomalies and provide better target drilling definition for programmes to be undertaken later during 2019.”

Key to zones marked on images
FEATURE A - A two kilometre long, east-northeast to west-southwest trending, robust chargeability anomaly coincident with a subtle magnetic high, situated only two kilometres west of the Sao Chico mine and one kilometre west of the recently reported high grade intersections from West Vein drilling (see news release of 20 September 2018). This anomalous area lies within the Sao Chico structural corridor at the intersection of several interpreted fault sets, similar to the setting of the current Sao Chico operations.
FEATURE B - An elongate chargeability anomaly, parallel to Feature A and lying on the western edge of the survey area.
FEATURE C - A cluster of chargeability anomalies located in the northwest of the survey area and lying within the Sao Chico strike corridor.
FEATURE D - A chargeability/conductivity anomaly on the flanks of the Cinderella Anomaly, also hosted within a magnetic high.

Figure 4: Calculated Vertical Magnetic Gradient Image of the IP survey area. This image displays as red highs areas where the magnetic signature changes abruptly. Interpreted as changes in lithology or faults, the image highlights a number of NE-SW and WNW-ESE lineaments (structures) which are coincident with the IP conductivity highs in the figures above. This provides greater confidence for the targets within the chargeability and conductivity highs lying within structures.

Results
Geomag S/A Prospecções Geofísicas were contracted by Serabi to complete the data acquisition over approximately four months between 28 June 2018 and 12 November 2018 employing a mixed dipole/dipole configuration. The IP survey covered a 10 kilometre strike, capturing the structural trend which hosts the Sao Chico ore body and numerous historical artisanal gold occurrences. The purpose of the survey was to delineate both electrically resistive/conductive and chargeable features, which would indicate quartz veins and sulphide bearing mineralisation.
The survey totalled 107 line kilometres, with survey lines (traverses) spaced 200 metres apart. This survey now complements the 30 line kilometre IP survey that was completed in 2016.
Raw data files and inversions were provided by Geomag to Serabi Gold and data processing was completed by Mr David McInnes, an independent consulting geophysicist, at Montana GIS.
The surveyed area provides a comprehensive electrical resistivity and chargeability map of the Sao Chico district and, together with the detail airborne electromagnetic and magnetic surveying recently completed and reported in the Company’s news release of 20 November 2018, provides an excellent foundation for the Company’s exploration activities in 2019.
Currently Serabi is undertaking further evaluation of the data in conjunction with its consultant independent geophysicist, in addition to follow-up structural interpretation, ground inspection, geochemical and geological sampling of the anomalous areas derived from this survey.
