The Pribbenow mine is located approximately 12 kilometres southeast of the town of La Loma and 17 kilometres east of the village of La Jagua de Ibirico. Pribbenow is a surface mine that uses a combination of dragline and truck-and-shovel mining methods working in slightly dipping seams. In 2013, a barge ferrying coal at Puerto Drummond overturned and sunk. The incident resulted in the Colombian government suspending Drummond's export license for nearly a month and implementing a new regulation requiring direct ship loading as at 1 January 2014. Production at Pribbenow was set to steadily decline towards the end of the decade before new reserves were discovered in the south of the tenement. This not only extends the asset life but also allows Drummond to postpone Similoa Rincon Hondo's startup. Pribbenow's main product is an unwashed low-sulphur, low-ash bituminous coal destined for the export thermal coal market.
