Significant increase in strike extensions with multiple high grade intersections into the Serra, Meio and Galena veins at Coringa
Serabi Gold Plc (AIM: SRB, TSX: SBI), the Brazilian focused gold mining and development company, is pleased to announce that exploration drilling conducted on its wholly-owned Coringa gold project has returned multiple high grade gold intersections on the Serra, Meio and Galena ore zones of the deposit.

Recent drilling targeting both strike and plunge extensions along these three main zones has demonstrated a series of high grade intersections significantly extending the previously modelled zones. A total of approximately 5,000 metres has been drilled to date.
Highlights
- Strike of the Meio #2 vein extended for a further 480 metres to the south increasing the total drilled strike of the Meio #2 vein to almost 1,200 metres.
- Depth extension of Meio #4 vein increased by approximately 200 metres along a 400 metre strike zone to the north.
- Galena vein strike extension increased by 100 metres to the south.
- Mineralisation in the Serra vein for a further 150 metres down dip and 140 metres along strike to the north.
Significant new intersections returned include;
- Galena - 2.0m @ 25.02g/t Au from 141.50m (COR0367) including 1.0m @ 48.18g/t Au
- Serra – 4.0m @ 3.36g/t Au from 354.0m (COR0370) including 1.28m @7.45g/t Au.
- Meio #2 – 0.35m @ 15.57g/t Au (COR0372) from 197.05m
- Meio #2 – 1.30m @ 32.04g/t Au (COR0373) from 144.75m including 0.5m @ 79.47g/t Au
- Meio # 4 – 0.60m @ 4.65g/t Au (COR0378) from 210.70m
- Meio #4 – 0.75m @ 7.82g/t Au (COR0380) from 174.8m
- Meio #4 - 1.40m @ 14.69 g/t Au (COR0381) from 275.0m including 0.70 m @ 19.88 g/t Au
The holes formed part of step out drill programme which commenced in October 2018 and has focused on strike and depth extensions upon the ore zones.
CEO Mike Hodgson commented: “We are very happy with the exploration drilling results to date as they demonstrate significant depth and strike extensions to the main veins at Coringa. We are already well advanced with the preparation of an updated geological resource estimate and I believe that these results will translate into significant resource growth. The updated resource estimation which is planned for release before the end of the first quarter, will be followed by a Preliminary Economic Assessment (PEA) the results of which, I hope, can be published before the end of the second quarter.
“As well as the ongoing drilling, we are continuing preparations to go underground at Coringa, which has principally involved some site clearance as we develop the portal. We have the Trial Mining License (GUIA) which permits underground development, and we hope to be underground and into the first ore during the second quarter. This will provide invaluable understanding of the ore body geometry which, given the nature of narrow, vertically dipping orebodies, can be difficult to understand from drill hole data alone.”

Drill Results
The Galena vein was targeted with four holes completed along the strike of the vein targeting the down plunge position of the defined mineralisation. The program successfully intersected high grade mineralisation over mineable widths and with hole COR0367 extended the known mineralisation for a further 100 metres to the south of the previously known limit.
Similarly, a series of four holes have been completed on the Serra vein set. Drill hole COR0370 targeted the down dip and northern strike extension of the modelled ore zones and successfully in intersected a four metre drilled width of veining and alteration which has extended the mineralisation for a further 150 metres down dip and 140 metres along strike to the north from the previous drill intersections of the Serra mineralisation.
A series of nine drill holes have to date been completed along the Meio vein set, targeting the Meio #2 (“M2”) and Meio #4 (“M4”) veins. The Meio #1 (“M1”) vein is the most strike extensive and drilled vein defined to date with numerous intersections along a total strike length of 1,500 metres. The M2 vein which lies parallel to M1 had previously, however, only been defined along a total strike length of 700 metres. The M4 vein is considered to be a southern extension of the M1 vein in a structurally off set position and past drilling had defined the mineralisation over a 900 metre strike length.
Drill holes COR0372 and COR0373 targeted the southern strike extension of the M2 vein, successfully intersecting the structure and significantly extending the strike of the M2 vein for a further 480 metres to the south making the drilled strike of the M2 vein to almost 1,200 metres and it remains open along the southern strike.
Drill holes COR0378, COR0380 & COR0381 targeted, over a strike extent of 400 metres, the northern dip extension of M4 vein at depth. This drilling has successfully extended the vein for approximately 200 metres deeper than previously known along this 400 metre strike.
The drill program is continuing at Coringa with further strike extension positions targeting the southern strike of the Meio vein set and the Galena vein.
