 Final Exploration Results for Coringa ahead of Preliminary Economic Assessment  

Serabi Gold (AIM:SRB, TSX:SBI), the Brazilian focused gold mining and development company, is pleased to announce some additional drilling results from the conclusion of the surface drilling programme that was conducted at its wholly-owned Coringa gold project located in Para state.

Coringa Drilling Highlights

  • Hole COR0381 - intersected 2.65m @ 8.51 g/t gold (inc. 1.40m @ 15.82 g/t gold)
  • Hole COR0383 - intersected 1.15m @ 9.69 g/t gold (inc. 0.6m @ 17.74 g/t gold)
  • Hole COR0380 - intersected 0.75m @  7.61 g/t gold
  • Hole COR0374 - intersected 0.80m @  0.44 g/t gold
  • Hole COR0377 - intersected 0.70m @  0.39 g/t gold

CEO Mike Hodgson commented:

These are the final results from the Coringa 2018-2019 drill campaign, the initial results of which underpinned the NI 43-101 compliant geological resource update, details of which were issued on 4 March 2019.  That update resulted in a 37% increase in the total geological resource, so I am very pleased with the results of these final holes, which were not fully included in that updated geological resource and should contribute to a further increase in the total geological resource. This drilling campaign, which began in the fourth quarter of 2018, has increased the Meio resource significantly, extending the payable zone by some 575m of strike length to the south.  The last holes drilled, COR0381 and COR0383 were drilled into this payable southern extension, with both intersecting excellent grades over mineable widths.  COR0383 is especially pleasing as it is close the southern limit of the new payable zone, and the results suggest there is even more potential to the south.   

“From our experience at Palito and Sao Chico, we know that infill drilling on these veins from surface is impractical and that the best understanding is obtained from underground development and underground drilling.  With the GUIA trial mining license (“GUIA”) in place, we are just awaiting final blasting permits, and once these are obtained, intend to commence an exploratory ramp into the Serra zone at Coringa, providing us with bulk sample data and better understanding to the orebody geometry.

“Whilst a new Preliminary Economic Assessment (“PEA”) is well underway, it is clear the Meio vein is shaping up to be a very significant orebody that has now been traced for a strike length of well over 1.3 kilometres. These additional drilling results are being incorporated into a further revision of the geological resource, which in turn will be incorporated into the PEA on the Coringa Project, results of which are expected to be disclosed before the end of July 2019.”  

Drilling Results

The assay results for the six holes in this release were not included in the NI 43-101 compliant geological resource estimation published on March 4 2019.  These six results represent the final 2 holes (COR0382 and COR0383) of the drill programme, together with the assays results from the independent laboratory (SGS Geosol, Belo Horizonte) for four holes where the previous disclosure was only of assays results generated by the Company’s own laboratory. 

Hole COR0383 targeted the Meio #2 vein and intersected 1.15m @ 9.69g/t Au (including 0.6m @ 17.74m) from 134.2 metres down hole depth. This intercept was a significant ‘step out’ hole, increasing the total drilled strike of the Meio #2 vein to 1,300 metres. 

External laboratory analyses have now been received from SGS Geosol (“SGS”) for drill holes COR0374, COR0377, COR0380 and COR0381. Whilst these drill holes were used to assist the geological interpretation of the Meio vein, the internally generated assay data was excluded from the previous resource estimation. 

The final assay results from the four previously disclosed drill holes together with the assay results from the final two drill holes are listed below:

Reported intercepts calculated based on a minimum weighted average grade of 0.3g/t Au using a 0.5g/t Au weighted average lower cut and a maximum internal waste interval of 1.2m based on SGS reported analyses.

These drill holes formed part of step out drill programme along the strike projection of the structures focussed on testing the strike or plunge projections of a number of the key lode structures which commenced in mid-2018.

The Company has also undertaken a re-logging and re-sampling programme that was completed on historic Coringa drill holes in the first half of 2019.  A total of 179 early Coringa drill holes were reassessed. Re-sampling was completed on 43 of the 179 drill holes honouring geological contacts and quartz vein structures. A total of 92 core samples were analysed and significant grade increases reported in many mineralised intersections, as a consequence of the exclusion of the dilution effects of unmineralised host wall rocks that the previous owners had included within the sampled intervals.  These improved intercepts are now being used in a further revision of the geological resource estimate and will be incorporated in the PEA the initial result of which are due to be issued before the end of July 2019.
