The Mocoa deposit is located in the department of Putumayo 10km from the town of Mocoa. It was discovered in 1973 when the United Nations (UN) and the Colombian government, conducted a regional stream geochemical survey. Between 1978 and 1983, an exploration program was carried out that consisted of geological mapping, surface sampling, ground geophysics (IP, magnetics), 31 diamond drill holes totalling 18,321m, and metallurgical test work cumulating in a positive pre-feasibility study. B2Gold subsequently executed diamond drill programs in 2008 and 2012.
A pit-constrained resource at Mocoa contains 636 million tonnes of 0.45% copper equivalent at 0.25% cut-off containing 4.6 billion pounds of copper and 511 million pounds of molybdenum. Mocoa is open in both directions, along strike and at depth. Additional porphyry surface targets have been identified and are drill ready. Currently, the value is being unlocked with community engagement and drill permitting.
