GOLD: Construction update for Continental’s Buritica project



COLUMBIA – Toronto-based Continental Gold says its Buritica gold project in Antioquia is on schedule. The first gold pour will take place in the first half of 2020, followed by a six-month ramp-up period.

The company reports that construction is 44% complete, and underground development is also 44% complete. So far 6,274 metres have been finished ahead of schedule. Detailed engineering is 93% done. The processing plant earthworks are 76% complete with mechanical installation to begin in early 2019. The powerline is being installed for completion in early Q3 2019.

Buritica has been a very small, 30-t/d mine operated by Continental for over 20 years. The mine is being transformed into a high grade underground gold mine for a capex of $500 million (give or take $25 million). The initial mining rate will be 2,100 t/d, but that will ramp up to 3,000 t/d by year three. Gold recovery will be achieved by crushing, SAG milling in closed circuit with a pebble crusher and ball mill. Both the SAG and ball mill discharge will feed a gravity circuit. The gravity tails will be cycloned and the underflow leached in agitated tanks. Leached slurry will be thickened, and sent to a Merrill Crowe circuit to recover the gold.

Continental is working on an updated mineral resource estimate due in Q1 2019. An updated mine plan with follow shortly after.
