Gran Colombia Gold Corp. [CGM-TSX; TPRFF-OTC] has reported assay results from the ongoing 2017 diamond infill drilling program at its Providencia underground gold mine at its 100%-owned Segovia Operations 130 km northeast of Medellin, Colombia.
Infill drilling at Providencia was aimed to further delineate one of the main high-grade orebodies on which sparse previous surface drilling had intersected high gold grades. Multiple high gold grades generated from 19 drill holes (1,119 metres) drilled from underground in the 2017 drilling program were intersected on the main vein system with maximum grades of 649.1 g/t gold over 0.39 metres and 249.3g/t silver over 0.95 metres.
Serafino Iacono, Executive Co-Chairman of Gran Colombia, said, “We are pleased to report that the assay results returned from the ongoing Providencia infill drilling program represent some of the highest grades seen at Providencia so far, which further increases our confidence in the potential for adding new resources to the mine and extending its mine life. The underground mine at Providencia is one of the highest-grade mines in Colombia and it continues to contribute to our production growth and free cash flow generation from our Segovia Operations.”
Drilling results from the Providencia Mine confirm the previously modelled high-grade nature, strong down-plunge continuity of gold mineralization and the thickness of one of the main orebodies currently in production on Level 14. This orebody remains open at depth and company geologists believe it offers the potential for additional resource growth.
The high-grade gold mineralized intercepts associated to this main orebody confirm the higher grade mineralization at depth, which could have a positive impact on the increase of the mining production at Providencia. The Providencia drill program continues to increase the confidence in the geological model of the orebodies through increased drill density.
Highlights also included 67.39 g/t gold over 2.74 metres 54.40 g/t over 4.40 metres and 53.60 g/t over 5.60 metres. Refer to company press release for complete assays.
